Description

TECHNICAL FIELD The present invention relates to a textile product for an ostomy appliance and an ostomy appliance. More specifically, it relates to a textile product for an ostomy appliance and an ostomy appliance for constructing the ostomy appliance.

Occasionally, a stoma, such as an artificial anus or an artificial bladder, is created in the body due to a disease or the like. Since the stoma cannot control the excretion of wastes by itself, the stoma holder generally lives with an ostomy appliance equipped with a bag (ostomy pouch) for storing the wastes. As a result, stoma holders can collect waste products at any time, which greatly contributes to improving the lives of stoma holders.

On the other hand, it is said that users of ostomy appliances often have a psychological burden because they feel uneasy that the odor of stored waste will leak from the ostomy pouch and cause discomfort to people around them. In fact, a research report (Grant-in-Aid for Scientific Research Project No. 26560073) shows that stoma exhaust gas contains four times the concentration of hydrogen sulfide compared to the stool odor of healthy subjects, and when onions are eaten, the concentration increases eight times. research report) is known. For this reason, there is a strong demand for a technique for effectively suppressing leakage of odors from the ostomy appliance. As such a technique, the technique disclosed in Patent Document 1 below is known.

JP-A-01-299551 International Publication No. 2015/194334 Pamphlet

The waste excreted from the stoma includes not only solid matter (excretion) and liquid matter (excretion, exudate, secretion, etc.), but also gas (excretion gas). Then, it becomes necessary to release the gas to the outside of the ostomy pouch so that the ostomy pouch is not inflated by the gas.
In this regard, the ostomy pouch of US Pat. No. 5,900,003 is made of EBA (ethylene butyl acrylate) and has an intermediate wall 30 with about 248,000 puncture holes per square meter. This intermediate wall 30 prevents contact between the filter and liquid or solid waste, thereby maintaining filter performance.

However, if the degree of blockage of the intermediate wall 30 is increased to prevent contact between the filter and the waste matter, the air permeability will naturally decrease accordingly, making it difficult for the gas in the ostomy pouch to escape to the outside. On the other hand, if the degree of blockage of the intermediate wall 30 is weakened, there is a conflicting problem that liquid and solid wastes in the ostomy pouch are likely to come into contact with the filter.
In this regard, there is a problem that ostomy pouches with filters that are actually on the market are not sufficiently degassed, and the pouches continue to swell. For this reason, the user has no choice but to open the exhaust port several times a day to "bleed" without going through the filter, and the odor at that time poses a problem. That is, even if a filter is provided to prevent the pouch from being excessively inflated by the gas stored in the ostomy pouch, the structure must be such that liquid does not leak when the pouch is pressed during normal use. From the balance of , it is considered that there also exists a problem that the air permeability of the filter cannot be sufficiently increased.

Furthermore, the filter can be clogged by contact with the liquid or solid waste material stored in the ostomy pouch, and the filter performance can be reduced, especially waste material from the stoma contains a large amount of oil and fat. has been found to be a problem. For example, in an ileostomy constructed by guiding the ileum to the body surface, bile acid absorption at the terminal ileum may be insufficient, resulting in a large amount of fat-soluble bile acid being contained in waste products. In addition, lipid malabsorption in the ileum is likely to occur, and waste products may contain a large amount of lipid. It has been found that there is a problem that when the oil and fat contained in the waste comes into contact with the filter, the filter performance is particularly greatly reduced. In this regard, the technique of Patent Document 1 uses a carbon-impregnated open-cell polyurethane foam as a filter medium. Since the deodorizing mechanism of carbon (activated carbon, etc.) is physical adsorption to pores, there is a problem that the deodorizing ability is greatly reduced due to contact with fats and oils as described above.

In addition, although the technique disclosed in the above Patent Document 2 is disclosed as a deodorant mask by the present inventor, the focus is on the fact that it can be used for stoma appliances, the problem of contact with oils and fats, and further, No study has been made on a configuration capable of maintaining the deodorant performance even when in contact with fats and oils.

[1] Textile product for ostomy appliance The textile product for ostomy appliance (1) of the present invention is for constituting an ostomy appliance,
A fiber assembly (11), a deodorant (12) attached to fibers (111) constituting the fiber assembly (11), and a binder resin (13) attaching the deodorant (12) to the fibers. ) and
Furthermore, among these, the deodorant (12) contains an inorganic deodorant containing a metal element,
The binder resin (13) contains a polymer having a solubility parameter (SP value) of 10.0 or more (see FIG. 1).

As used herein, the term "stoma" includes the meaning of an excretory pore formed by guiding the digestive tract or urinary tract to the outside of the body. These stomas are usually created in the abdominal wall of the body. Therefore, in the present invention, a stoma includes a gastrointestinal stoma formed by guiding the gastrointestinal tract to the outside of the body and a urinary tract stoma (urostoma) formed by guiding the urinary tract to the outside of the body. Furthermore, the gastrointestinal stoma mentioned above includes an ileostoma formed by guiding the ileum to the outside of the body and a colostoma (colostoma) formed by guiding the large intestine to the outside of the body. In addition, the above-mentioned urinary stoma includes an ileal conduit, a ureteral skin fistula, a renal fistula, a bladder fistula, and the like. The ostomy appliance includes all appliances having an opening for receiving the stoma described above.

As described above, the fiber product for an ostomy appliance uses an inorganic deodorant as a deodorant, and has a polymer having an SP value of 10.0 or more (hereinafter also simply referred to as "hydrophilic polymer"). ) is used as a binder resin. Therefore, it can exhibit particularly excellent deodorizing performance as a textile product for stoma appliance. In particular, it has excellent deodorizing properties in the presence of oil (oil and lipophilic components). Also, in the aqueous system as well, it is excellent in that it can form an effective deodorizing field for sulfur-based components that are water-soluble among odorous components.

Specifically, for example, compared to the waste products (stool, urine, etc.) of non-stoma patients, the waste products discharged from stoma patients into the ostomy pouch contain more oil and lipophilic components (such as bile acids). tend to be Therefore, when a conventional textile product is used as a ventilation filter for an ostomy pouch, the oil easily adheres to the textile product due to contact with the oil, which may impede breathability. In addition, in textile products containing activated carbon, which has been widely used as an adsorbent, the activated carbon has the property of easily adsorbing oil, so the activated carbon may be saturated and clogged with oil early after use.
In this regard, the textile product for an ostomy appliance of the present invention can exhibit excellent deodorizing performance even in the environment described above. This is probably because the inorganic deodorant is included as a deodorant, and the deodorant is attached to the fiber by a hydrophilic polymer, so that the above-mentioned oil content does not inhibit deodorization. . Furthermore, since the deodorant and the binder resin have a high affinity for the deodorant and the binder resin, the deodorant can be firmly attached and fixed to the fibers with a smaller amount of the binder resin in the textile product for the ostomy appliance, so the deodorant can be used effectively. It is considered that

(1) Fiber assembly The "fiber assembly" is a fiber assembly in which a plurality of fibers are entangled with each other, and has the function of maintaining the deodorant on the fibers while ensuring air permeability. As the fiber assembly, for example, nonwoven fabric, woven fabric, knitted fabric, and the like can be used. These may use only 1 type and may use 2 or more types together. Among these, nonwoven fabrics are preferable from the viewpoints of easy setting of a desired thickness, easy control of air permeability, and low manufacturing cost.

Moreover, the kind of nonwoven fabric is not limited, and the nonwoven fabric obtained by any manufacturing method may be used. For example, (1) a nonwoven fabric obtained by melt spinning, (2) a nonwoven fabric obtained by a physical entangling method, (3) a nonwoven fabric obtained by a heat fusion method, (4) entangled using an adhesive A nonwoven fabric etc. are mentioned. Among them, examples of the nonwoven fabric (1) include spunbond nonwoven fabrics and meltblown nonwoven fabrics. Nonwoven fabrics of (2) include air-entangled nonwoven fabrics, hydroentangled nonwoven fabrics (spunlace), needle-punched nonwoven fabrics, and the like. Nonwoven fabrics of (3) include thermal bonded nonwoven fabrics and embossed nonwoven fabrics. Nonwoven fabrics of (4) include various chemical bond nonwoven fabrics. These may use only 1 type and may use 2 or more types together. Among these, spunbonded nonwoven fabrics, spunlaced nonwoven fabrics, needle punched nonwoven fabrics, thermal bonded nonwoven fabrics, and the like are preferred from the viewpoint of retention of the deodorant, air permeability, and the like.

The fibers constituting the fiber assembly are not limited, and examples thereof include organic fibers (resin fibers, vegetable fibers, etc.), inorganic fibers (glass fibers, carbon fibers, metal fibers, etc.), composite fibers thereof, and the like. Among these, organic fibers are preferred.
Among organic fibers, resin fibers are preferred. The resin constituting the resin fiber is not limited, but examples thereof include polyester, polyethylene, polypropylene, polyvinyl chloride, polyacrylic acid, polyamide, polyvinyl alcohol, polyurethane, polyvinyl ester, polymethacrylate, and rayon. These may use only 1 type and may use 2 or more types together. Among these, polyester, polyethylene, polypropylene and rayon are preferred, and polyester, polyethylene and polypropylene are more preferred.

Hydrophilic resin fibers can be used as the fibers constituting the fiber assembly. Examples of hydrophilic resin fibers include resin fibers containing polyvinyl alcohol, and resin fibers containing hydrophilic polymers into which hydrophilic groups (polar groups such as OH groups) are introduced by modification or the like. These may use only 1 type and may use 2 or more types together. More specifically, a hydrophilic polymer having a solubility parameter (SP value) of 10.0 or more is included as a resin component of fibers contained in the fiber assembly. A fiber assembly containing such hydrophilic resin fibers may become wet due to contact with water contained in the waste material stored in the ostomy pouch. In this regard, hydrogen sulfide, which is one of the components with the strongest odor in waste products, has excellent solubility in water. For this reason, hydrogen sulfide is dissolved in water adhering to the hydrophilic resin fibers, captured, and then brought into contact with a deodorant to deodorize.

When the fiber assembly contains hydrophilic resin fibers, the SP value of the resin component constituting the hydrophilic resin fibers is measured or calculated in the same manner as in the case of the binder resin described later. Furthermore, the SP value (SP ₁ ) of the resin component composing the hydrophilic resin fiber and the SP value (SP ₂ ) of the resin component composing the binder resin may be the same or different. If different, the closer values are preferred. Specifically, 0≦|SP ₁ −SP ₂ |≦2 is preferred, 0≦|SP ₁ −SP ₂ |≦1 is more preferred, and 0≦|SP ₁ −SP ₂ |<1 is particularly preferred.

In the case where two or more different resin fibers are included as described above, a high-melting-point resin fiber made of a resin with a relatively high melting point and a low-melting-point resin fiber made of a resin with a relatively low melting point are used. A combined fiber aggregate can be used. That is, for example, a fiber aggregate having polyester resin fibers as high-melting resin fibers and polyolefin resin fibers as low-melting resin fibers can be mentioned. In such a fiber assembly, when the fiber assembly is welded to another component, it can be welded using only the low melting point resin fibers. In this case, when the total of the high melting point resin fiber and the low melting point resin fiber is 100% by mass, the low melting point resin fiber can be, for example, 10 to 80% by mass, and further 20 to 70% by mass. can do.

Also, the resin fiber may contain no additive, but may contain an additive. Examples of additives include antioxidants, plasticizers, antistatic agents, antibacterial agents, antifungal agents, reinforcing agents, stabilizers, and the like. These may use only 1 type and may use 2 or more types together.
Furthermore, the average fiber diameter of the fibers constituting the fiber assembly is not limited, but can be, for example, 5 to 30 μm, preferably 10 to 25 μm. The average fiber diameter is calculated by calculating the average value A ₁ (average of 3 locations) of actually measured fiber diameters measured using an optical microscope at 3 different locations of fibers (usually, single fibers) constituting the fiber assembly, Let it be the further average A ₂ of A ₁ for 50 randomly selected fibers (50 average).

(2) Deodorant The "deodorant" is a component having a deodorizing property, and is a solid adhered to the fibers constituting the fiber assembly via the binder resin. The deodorant used in the present invention is an inorganic deodorant containing a metal element, and is preferably a component capable of adsorbing and/or decomposing odorous components by chemical action to eliminate or reduce odor. In addition, among stoma odors, sulfur-based components (sulfur-based gas) containing sulfur elements tend to give off particularly strong odors. Therefore, the deodorant contained in the textile product for an ostomy appliance of the present invention preferably has an excellent deodorant effect on sulfur-based components (eg, hydrogen sulfide and thiol compounds).

The structure and type of the inorganic deodorant containing a metal element are not limited, but the inorganic deodorant is an inorganic compound having a deodorizing effect, or an inorganic compound having a deodorizing effect as a main component. is preferred.
Examples of the inorganic compound include oxides (including composite oxides with other oxides), hydroxides, inorganic acid salts (phosphates, silicates, sulfates, carbonates, etc.). These may use only 1 type and may use 2 or more types together.
Metal elements contained in inorganic deodorants include Cu, Zn, Zr, Ti, Ni, Co, Fe, Mn, Ag, W, Se, Al, Mg, Ca, Sr, Ba, and the like. . These may use only 1 type and may use 2 or more types together. Among these, Cu, Zn and Zr are preferable, and Cu and Zn are particularly preferable, from the viewpoint of deodorizing action against stoma odor. These inorganic deodorants containing Cu and/or Zn can exert an excellent deodorizing action against the sulfur-based components (sulfur-based gas) described above. In particular, it is excellent in that it can efficiently and irreversibly deodorize the sulfur-based gas through a chemical reaction with the sulfur-based gas.

Specifically, oxides include CuO SiO ₂ composite oxide, ZnO SiO ₂ composite oxide, copper oxide, zinc oxide, zinc aluminum oxide, zinc silicate, zinc aluminum silicate, zinc layered aluminosilicate, Titanium oxide, aluminum oxide, magnesium oxide, calcium oxide, strontium oxide, barium oxide, zirconium oxide, tungsten oxide, cerium oxide, lithium oxide, sodium oxide, potassium oxide, zeolite (synthetic zeolite, mineral-derived zeolite), white clay, etc. be done. These may use only 1 type and may use 2 or more types together. Moreover, in order to function more effectively as a deodorant, various treatments (for example, activation treatment) may be applied (for example, activated clay, activated alumina, activated zinc oxide, etc.). Among these, _CuO.SiO2 composite oxides and/or _ZnO.SiO2 composite oxides are preferred. Among these, the CuO.SiO ₂ composite oxide can be said to be, for example, a support in which copper oxide is supported on silica gel. Also, the ZnO·SiO ₂ composite oxide can be said to be, for example, a support in which zinc oxide is supported on silica gel.

Inorganic salts include phosphates such as ZrCu(PO ₄ ) ₂ ·H ₂ O (copper zirconium phosphate hydrate). The above copper-zirconium phosphate hydrate can be obtained, for example, by reacting layered zirconium phosphate Zr(HPO ₄ ) _{2.H 2} O with a divalent copper salt. The substance may contain impurities such as raw materials or parts thereof.
Additionally, inorganic salts include sulfate salts such as copper sulfate and zinc sulfate. These may use only 1 type and may use 2 or more types together. In addition, these sulfate compounds can be used in combination with silica gel composed of inorganic compounds (such as SiO ₂ ) that do not contain metal elements as deodorants that are more effective against stoma odors.

The shape of the inorganic deodorant containing a metal element is not limited, and various shapes are possible. For example, it can be granular, lumpy, acicular, or the like. In addition, it can be used as a porous form (activation) of primary particles, secondary particles (granulated particles, aggregated particles) obtained by aggregating primary particles, and the like. These may use only 1 type and may use 2 or more types together.
The size of the particles constituting the inorganic deodorant containing a metal element is also not limited, but for example, the volume-based median diameter can be 0.05 to 100 μm, preferably 0.1 to 50 μm. It is preferably from 0.2 to 30 μm. To exhibit an excellent deodorizing action by exposing the deodorant particles from within the binder resin without excessively covering the particles constituting the deodorant with the binder resin, by having a moderately large particle size. can be done. From such a point of view, for example, an inorganic deodorant made of a silicate is more likely to have a larger diameter than an inorganic deodorant made of a phosphate, so an inorganic deodorant with a large particle size is used. From the viewpoint of utilization, an inorganic deodorant made of silicate can be selected.
On the other hand, when large particles exceeding 100 μm are used, the surface area per unit mass of the exposed particles becomes small, which tends to make it difficult for the deodorant to act efficiently. The above median diameter is measured with a laser diffraction particle size distribution analyzer.

Furthermore, since the inorganic deodorant containing a metal element can exert an excellent deodorizing effect as the contact efficiency with the odor component is high, the ratio of the particles constituting the inorganic deodorant containing a metal element The surface area is preferably 5-800 m ² /g, more preferably 10-600 m ² /g. The specific surface area is measured by the BET method calculated from the nitrogen adsorption amount.

Although the amount of the inorganic deodorant (inorganic deodorant containing a metal element) contained in the present textile product for ostomy appliance is not limited, it is preferably 1 g/m ² or more, and 3 g/m ² or more. It is more preferably 5 g/m ^{2 or more, and particularly preferably 5 g/m 2} or more. On the other hand, the upper limit of the amount of the inorganic deodorant (inorganic deodorant containing a metal element) contained in the present textile product for ostomy appliance is not limited, but is usually 30 g/m ² (that is, 30 g/m ^{2 )} . below).
In addition, when the total amount of fiber aggregates constituting the present textile product for an ostomy appliance (the state in which the inorganic deodorant containing a metal element is not adhered) is 100 parts by mass, the inorganic deodorant containing a metal element The amount of the deodorant is preferably 1 to 60 parts by mass, more preferably 2 to 50 parts by mass, and particularly preferably 5 to 40 parts by mass.

In addition, as a deodorant constituting the fiber product for an ostomy appliance of the present invention, a deodorant other than the inorganic deodorant containing a metal element as described above is contained together with the inorganic deodorant containing a metal element. be able to. That is, other deodorants include inorganic deodorants that do not contain metal elements, organic deodorants (organic acids, organic acid salts, and other compounds), and natural deodorants (plants, minerals, etc.). deodorants derived from natural products) and the like. These may use only 1 type and may use 2 or more types together.
Activated carbon, which does not contain metal elements, has poor deodorizing action (action to decompose odorous components), and can physically adsorb not only odorous components but also many components such as dissolved components in solvents. can be re-released reversibly. In addition, since it has the property of easily adsorbing oil, it is not suitable as a deodorant in the present invention. However, activated carbon that has a deodorant action by being imparted with a metal element can be used as an inorganic deodorant containing a metal element in the present invention. That is, activated carbon to which a metal element is added to chemically decompose odorous components is included in inorganic deodorants containing a metal element.

More specifically, examples of the inorganic deodorants containing no metal element include carbon-based deodorants (activated carbon, graphite), silica gel (silica gel consisting essentially of silicon oxide), and the like. These may use only 1 type and may use 2 or more types together.

Incidentally, the SP value will be described later.

Examples of such hydrophilic polymers include polyester, polyvinyl alcohol, acetalized polyvinyl alcohol, polyvinyl butyral, polyvinyl ether, polyvinyl acetate, hydrophilic acrylic polymer, polyamide, alkyl cellulose (methyl cellulose, ethyl cellulose, etc.). , polyacrylamide, and polyurethane.

Moreover, the polyester skeleton constituting the hydrophilic polyester may be either an aromatic skeleton or an aliphatic skeleton. That is, it may be an aromatic polyester (aromatic hydrophilic polyester) or an aliphatic polyester (aliphatic hydrophilic polyester). These may use only 1 type and may use 2 or more types together. In addition, aromatic polyesters include polyesters consisting only of aromatic structural units, aromatic structural units (structural units derived from aromatic monomers, hereinafter the same) and aliphatic structural units (aliphatic monomer-derived structural units (the same shall apply hereinafter), and the ratio of aromatic structural units is higher than that of aliphatic structural units.

In the present invention, the SP value is described in "Polymer Handbook Second Edition" [H. Burrell: (1975)], pages IV-337 to IV-359.
That is, when the hydrophilic polymer is a homopolymer, its SP value is calculated by the following formula (1) based on the molecular attraction constant G of the constituent units constituting the homopolymer.
SP=dΣG/M (1)
(In formula (1), "d" is the density of the homopolymer (g/l), "ΣG" is the sum of the molecular attractive force constants in the molecule of the structural unit, and "M" is the structural unit. is the molecular weight (g/mol) of
On the other hand, when the hydrophilic polymer is a copolymer, the SP value is obtained by calculating the SP value of each homopolymer of each structural unit that constitutes the copolymer according to the following formula (1). It is calculated by adding together the SP values multiplied by the mole fraction of each structural unit. That is, for example, in the case of a copolymer having a structural unit A at a molar fraction of X _A % and a structural unit B at a molar fraction of X _B %, it is calculated by the following formulas (2) to (4).
SP=SP _A ×(X _A /100)+SP _B ×(X _B /100) (2)
SP _A =d _A ΣG _A /M _A (3)
SP _B =d _B ΣG _B / _MB (4)
(In the formulas (2) to (4), “d _A ” is the density (g/l) of the homopolymer consisting of the structural unit A, and “ΣG _A ” is the molecular attraction force in the molecule of the structural unit A. is the sum of constants, “M _A ” is the molecular weight (g/mol) of the structural unit A, “d _B ” is the density (g/l) of a homopolymer consisting of the structural unit B, and “ _ΣGB ” is the sum of the molecular attractive constants in the molecule of the structural unit B, and “M _B ” is the molecular weight (g/mol) of the structural unit B).

The above-described hydrophilic polymer (polymer having an SP value of 10 or more) has a larger SP value than conventionally used binder resins such as aqueous acrylic emulsions. preferred.
Moreover, when the hydrophilic polyester and polyvinyl alcohol described above are compared, it is more preferable to include the hydrophilic polyester as the binder resin. Polyvinyl alcohol is often more water-soluble than hydrophilic polyester. This is because the water-soluble binder resin tends to swell when it comes into contact with water, and may cause clogging.

For this reason, the textile product for an ostomy appliance was immersed in water at a temperature of 25°C for 60 minutes, pulled out of the water, and then dried without heating _. W ₁ after immersion and drying) is preferably 30% or less (W ₀ −W ₁ /W ₀ ≦0.3). This mass reduction ratio is more preferably 25% or less, and particularly preferably 20% or less.

The amount of the binder resin contained in the present textile product for an ostomy appliance is not limited, but the binder resin is preferably 10 to 200 parts by mass, more preferably 30 to 100 parts by mass, based on 100 parts by mass of the deodorant as a whole. , 40 to 60 parts by mass is more preferable. This ratio is particularly preferable when the total amount of the binder resin is a hydrophilic polymer and the total amount of the deodorant is an inorganic deodorant containing a metal element.

Although the air permeability of the present textile product for an ostomy appliance is not limited, for example, the air permeability measured by the Frazier method of JIS L1096:2010 is preferably 40 to 400 cm ³ /(cm ² ·s), more preferably 60 to 350 cm ^{3 .} /(cm ² ·s) is more preferable, and 100 to 300 cm ³ /(cm ² ·s) is even more preferable. Within this range, a sufficient deodorant effect can be exhibited without interfering with gas flow inside and outside the ostomy pouch.
The basis weight of the textile product for ostomy appliance is not limited, but is preferably 15 to 100 g/m ² , more preferably 20 to 90 g/m ² , still more preferably 30 to 80 g/m ² . Within this range, sufficient air permeability and deodorizing effect can be obtained as a textile product for stoma appliance.

The textile product for an ostomy appliance of the present invention may consist of only one layer, or may consist of two or more layers. When it consists of two or more layers, for example, other fiber assembly layers, film layers, pressure-sensitive adhesive layers, etc. can be used. These may use only 1 type and may use 2 or more types together.
That is, for example, the following (1) to (5) are exemplified as multi-layered textile products for ostomy appliances.
(1) A textile product for an ostomy appliance consisting only of layer _S1 (layer _S1 is a fiber assembly in which a deodorant is adhered to constituent fibers via a binder resin, see FIG. 1).
(2) A fiber product for an ostomy appliance in which Layer _S1 and Layer _S2 are laminated (Layer _S2 is a deodorant other than an inorganic deodorant containing a metal element in constituent fibers via a binder resin. The fiber assembly, layer S ₁ and layer S ₂ , may be laminated with or without being entangled, see Fig. 2a).
(3) A textile product for an ostomy appliance in which layer _S1 and layer _S3 are laminated (layer _S3 is a film layer, for example a waterproof layer, see Fig. 2a).
(4) A textile product for an ostomy appliance in which layer _S1 and layer _S4 are laminated (layer _S4 is a film layer, for example, when layer _S4 is a waterproof layer, see Fig. 2a).
(5) A textile product for an ostomy appliance in which layer _S1 , layer _S4 , and layer _S5 are laminated in this order (layer _S4 is a film layer, for example, layer _S4 is a waterproof layer, layer _S5 is the adhesive layer, see Figure 2b).

The textile product for an ostomy appliance of the present invention only needs to have the above structure, and its manufacturing method is not limited. It can be obtained by applying (padding, dipping, coating, spraying, printing, etc.) a working fluid containing a resin and then drying it.
Among these methods, the padding method and the immersion method can more uniformly fix the deodorant to the surface of the base fabric than the other methods. As a result, the deodorant is more exposed to the air layer surface, and it is possible to obtain a textile product for an ostomy appliance that can exhibit more excellent deodorant performance. Examples of the padding method include a pad dry method and a pad steam method.

Additives other than the deodorant and the binder resin may be added to the working liquid. Additives include dispersants, antifoaming agents, viscosity modifiers, surfactants, pigments, dyes, fragrances, antibacterial agents, antiviral agents, antiallergen agents, and the like.
When two or more different deodorants are used in combination, a plurality of individually prepared working liquids can be used for the spreading process, if necessary.

The fiber assembly on which the working liquid has been spread can be dried by heating (for the purpose of removing the medium contained in the working liquid, etc.), if necessary. In this case, it is preferable to heat in the range of 110°C to 150°C. Within this range, the peculiar odor caused by heating can be suppressed. This temperature is more preferably in the range of 120°C to 140°C, and particularly preferably in the range of 123°C to 138°C in consideration of productivity. Furthermore, the drying time is not limited, but can be 2 to 10 minutes, preferably 2 to 5 minutes.

[2] Use of textile product for ostomy appliance The textile product for ostomy appliance of the present invention can be used as a part constituting an ostomy appliance. Although specific applications are not limited, for example, it can be used as a deodorizing filter for an ostomy pouch that constitutes an ostomy appliance. Further, the textile product for ostomy appliance of the present invention can be used as a deodorizing sheet for ostomy pouches constituting ostomy appliance. In this case, the deodorizing sheet for ostomy pouch can be a sheet that covers at least part of the outside of the ostomy appliance.
These configurations are detailed in the description of the ostomy appliance below.

[3] Ostomy appliance (1)
The ostomy appliance 2 (see FIGS. 3 to 8) of the present invention includes a body-side side wall 22a having an opening 221 for receiving the stoma, and an outer side wall 22b opposed to the body-side side wall 22a. It has a pouch 21 .
At least one side wall 22 of the side wall 22a on the side of the body and the side wall 22b on the outside has a vent hole 23 for releasing the gas inside the ostomy pouch 21 to the outside, and at least one of the inside and the outside of the vent hole 23. and a ventilation filter 24 disposed on one side. This ventilation filter 24 contains the textile product 1 for an ostomy appliance of the present invention.

As described above, wastes are stored in the ostomy pouch, and since these wastes contain gas containing odorous components, the ostomy pouch is filled with gas and swells during use. . When the ostomy pouch swells, it tends to come off from the body, and when viewed from the outside of the clothes, the site where the ostomy pouch is worn may appear swollen. However, the conventional ventilation filter is blocked in a short period of time due to contact with the oil in the waste matter, and eventually a separate discharge port (reference numeral 29 in FIGS. 3 to 8) is opened to discharge the filled gas. There is a problem that I have no choice but to do it. Furthermore, there is a problem that deodorization cannot be performed in such an exhaust form.

In this regard, as described above, in the fiber product 1 for an ostomy appliance of the present invention, an inorganic deodorant containing a metal element (deodorant 12) is added to the fibers constituting the fiber assembly that is the support. A hydrophilic polymer is attached as a binder resin. Therefore, particularly excellent deodorant performance can be exhibited in stoma applications. In particular, it is excellent in deodorizing properties in the presence of oil (oil and lipophilic components), and can exhibit excellent deodorizing properties also in aqueous systems. That is, it is possible to prevent the deodorant from being coated with oil, which may be contained in a large amount in the waste matter stored in the ostomy pouch, and to prevent the fiber assembly from being clogged with oil. Furthermore, since the sulfur-based component, which emits a particularly strong odor, exhibits water solubility, it is possible to provide a hydrophilic reaction field that facilitates the reaction of this sulfur-based component with the deodorant. Therefore, by using the textile product 1 for an ostomy appliance of the present invention as the ventilation filter 24 of the ostomy appliance 2, excellent deodorizing properties can be exhibited while maintaining ventilation even in the presence of oil.

[2] Evaluation of textile products for ostomy appliance (1) Ordinary sensory test The test ostomy appliance 2 (Embodiment 2, FIGS. 6 to 6) was closed with one piece of the textile product for the ostomy appliance (which functions as the ventilation filter 24) of Examples 1 to 9 and Comparative Examples 1 to 4 cut to 40 mm. 8) was prepared.
Next, 500 mL of a test gas of hydrogen sulfide, methyl mercaptan, or ammonia having an odor intensity of 5 was injected into the ostomy pouch 21 of the ostomy appliance 2 . Furthermore, the ostomy pouch 21 (inner bag) filled with the test gas was enclosed in a 10 L polyethylene bag (outer bag) inflated with dry air. Then, one hour after this encapsulation, after confirming that the test gas had escaped from the ostomy pouch 21 (the side walls 22a and 22b were in close contact with each other), the gas inside the polyethylene bag was smelled for six months. A human test subject was allowed to sniff, and the odor intensity was determined according to the following criteria. Then, the odor intensity of the six people was averaged and shown in Tables 1 to 3 as the odor intensity of the normal sensory test. The smaller the odor intensity value, the higher the deodorizing effect. The concentration of the odor intensity 5 described above is 8 ppm by volume for hydrogen sulfide, 0.2 ppm by volume for methyl mercaptan, and 40 ppm by volume for ammonia.
Odor intensity 0: Odorless.

Odor intensity 5: Strong odor.

(2) Oil resistance sensory test Each of the textile products for stoma appliances of Examples 1 to 9 and Comparative Examples 1 to 4 was immersed in 100 mL of commercially available adjusted milk (milk fat content of 3.5% or more) for 1 hour. After rinsing with exchanged water (100 mL) three times, the odor intensity was determined in the same manner as in (1) above, except that the oil-adsorbed textile for ostomy appliance obtained by drying at 60°C for 30 minutes was used. did Then, similarly, the odor intensity of the six persons was averaged and shown in Tables 1 to 3 as the odor intensity of the oil resistance sensory test. The smaller the odor intensity value, the higher the deodorizing effect.

From the results in Table 1, it was found that when the binder resin contained a polymer with an SP value of 10 or more, even in an environment in contact with oil, the same excellent deodorizing effect as in an environment without contact with oil was achieved. It can be seen that That is, it can be seen that excellent oil resistance can be exhibited.
Specifically, Examples 1 to 3 using a polymer with an SP value of 10.6 to 12.6 as the binder resin and a polymer with an SP value of 8.4 to 9.3 as the binder resin Compared with Comparative Examples 1 and 2 used, there is almost no difference in the results of the normal sensory test (deodorization in an environment where oil is not present), while the oil resistance sensory test (deodorization in an environment where oil is present). was greatly reduced in Comparative Examples 1 and 2, in which a polymer having an SP value of 8.4 to 9.3 was used as the binder resin.

In this regard, when comparing Example 1 and Example 2, it can be seen that when a polymer having an equivalent SP value is used as the binder resin, equivalent results are obtained in the oil resistance sensory test. In addition, when comparing Examples 1 to 3, it can be seen that Example 3, which uses PVA exhibiting water solubility, is slightly inferior to Examples 1 and 2 in the normal sensory test, but is superior in the oil resistance sensory test. I understand. It is considered that this is because the deodorant is more covered with the binder resin in Example 3 than in Examples 1 and 2.

From the results in Table 2, it can be seen that inorganic deodorants containing metal elements can be used in various combinations. On the other hand, when activated carbon, which is an inorganic deodorant containing no metal element, is used, the SP value of the binder resin exerts a stronger effect, and the properties of the activated carbon itself are greatly affected, resulting in a sufficient deodorant effect. It turns out that it is not. Moreover, it can be seen that the results of the oil resistance sensory test are significantly inferior to those of each example.
Furthermore, from the results in Table 3, it can be seen that the spread amount of the inorganic deodorant containing a metal element can be used in a wide range of 3.0 to 12.0 g/m ² . Similarly, it can be seen that the spreading amount of the binder resin can be used in a wide range of 3.0 to 12.0 g/m ² . If the spread amount of the inorganic deodorant containing a metal element exceeds 12.0 g/m ² , the inorganic deodorant may come off. Similarly, even if the spread amount of the binder resin is less than 3.0 g/m ² , the inorganic deodorant may come off.

It should be noted that the present invention is not limited to the specific examples described above, and various modifications can be made within the scope of the present invention according to the purpose and application.
