Description

【００６９】
化１は、アクリロニトリルと他のモノマーとの重合によって形成された主鎖４２，４３を有しており、これら主鎖どうしが、橋かけＡ及びＢによって架橋結合されている。橋かけＡは、ニトリル基がヒドラジン処理によって架橋結合された部分である。また橋かけＢは、カルボキシル基に変換された一部が、多価金属Ｍの硝酸塩等によって金属塩とされた部分である。
【００７０】
前記架橋型アクリレート樹脂は、多価金属Ｍを含有するため、大気中の水分や汗などの水分が前記アクリル繊維に吸収されると、前記水分は、多価金属イオンに強く引き寄せられ、いわゆる水和の現象が起る。この水和によりエネルギーが放出され、熱が発せられるため保温効果が高くなる。
【００７１】
また上記の架橋型アクリレート樹脂は、温度が２０℃、相対湿度が６５％の環境下で、２０％以上の水分率を得ることが可能である。この保湿性によっても肌に暖かみを感じやすくなる。
【００７２】
さらに、不快な刺激臭を有するガスが発生したときに、上記架橋型アクリレートのｐＨ調整による脱臭作用によって、前記ガスがショーツの外部に漏れ出すことを適切に抑制する機能を有しているため、生理時の気になる臭いの発生も低減することができる。
【００７３】
また、前記保温機能を有する素材を含む織布で、前記つま先部５Ａ，５Ａやかかと部５Ｂ，５Ｂを形成してもよい。
【００７４】

BACKGROUND OF THE INVENTION
  The present invention includes a panty part that is in close contact with the body,Leg andHas a foot partUsed as pantyhose or tightsThe present invention relates to an exterior body, and more particularly, to an exterior body suitable for being used simultaneously with wearing of a body fluid absorbent article such as a sanitary napkin.
[0002]
[Prior art]
When wearing a bodily fluid absorbent article such as a sanitary napkin, the crotch has a waterproof function and a large clamping force to the body in order to keep the bodily fluid absorbent article in close contact with the crotch of the body It is practiced to wear sanitary shorts. In general, pantyhose may be worn together with the sanitary shorts, and a girdle may be worn to adjust the body shape.
[0003]
However, the sanitary shorts have a large tightening force to the body in order to prevent displacement of the body fluid absorbent article from the crotch part, and have a waterproof function, so that the air permeability is inferior. Therefore, there is a feeling of pressure on the lower abdomen and the buttocks when the sanitary shorts are worn, and the free movement of the body may be hindered. Moreover, when the sanitary napkin, pantyhose and girdle are worn in layers, a feeling of pressure is further generated and air permeability is impaired.
[0004]
Therefore, in Japanese Utility Model Laid-Open No. 3-128606, the support for the abdomen and buttocks is given by devising the knitting structure of the panty part of the panty king, and the body fluid absorbent article is attached to the crotch part by this support force. It is disclosed that it can be held.
[0005]
[Problems to be solved by the invention]
However, in the pantyhose disclosed in the above publication, the panty part can tightly adhere to the abdomen and buttocks of the body, but does not emphasize the function of pressing the body fluid absorbent article attached to the crotch part against the crotch part of the body. There is a possibility that the displacement of the bodily fluid absorbent article from the crotch portion cannot be reliably prevented.
[0006]
In addition, since the panty part strongly tightens the abdomen and buttocks, the wearer tends to feel a sense of pressure, and there is also anxiety of poor blood circulation due to the pressure.
[0007]
  The present invention solves the above-described conventional problems, and the panty unitIt has leg and foot parts and is used as pantyhose or tightsThe body fluid-absorbing article can be closely attached to the crotch portion, and as a result, shorts with a small pressing force can be worn on the inside, or wearing of shorts can be made unnecessary, increasing the degree of freedom of movement of the body. It aims at providing the exterior body suitable for wearing of the body fluid absorptive article which can be performed.
[0008]
[Means for Solving the Problems]
  The present invention provides a panty unit and the panty unitFromA pair of extending leg portions and, A foot part continuous to the lower end of the leg part;And the panty part has an elastic contraction force to adhere to the bodyUsed as pantyhose or tightsIn the exterior body
  The panty portion includes a back body, a front body, a waistline opening formed in the back body and an upper portion of the front body, and a crotch portion positioned between the back body and the front body.And
  The crotch part is provided with a crotch fabric having a liquid blocking function, and is used as an attachment part for a body fluid absorbent article,
  At least one extending in the height direction through the center of the back bodyHas elastic contraction forceA rear lifting member, and at least two members having a predetermined interval in the crotch width direction at the crotch portion and extending from the crotch portion toward the front bodyHas elastic contraction forceA forward lifting member is provided.
[0010]
When the exterior body of the present invention is worn, the bodily fluid absorbent article installed in the crotch is brought into close contact with the crotch part by the rear lifting member and the front lifting member provided in the panty part, and the body fluid absorbent article installed in the crotch part Can be prevented from being displaced. Therefore, it is not necessary to use shorts with excessive tightening force, or wearing of shorts can be made unnecessary, the feeling of pressure on the body is reduced, and the degree of freedom of the body is increased. Further, the air permeability can be ensured and the stuffiness is less likely to occur.
[0011]
In addition, it is preferable that the front lifting member is disposed so that the interval gradually increases from the crotch portion toward the front body.
[0012]
In the case where the front lifting member is provided, the body fluid absorbent article is pressed against the crotch portion of the body by at least two front lifting members at the crotch portion. Moreover, since the space | interval of a front lifting member is spreading gradually in the front body, the applied pressure to a lower abdominal part of a body will disperse | distribute, and it will become difficult to produce a feeling of pressure. Moreover, when the front lifting member whose interval is gradually widened is located in the front body, the feeling of wearing in the lower abdomen is improved.
[0013]
  For example, the rear lifting member and the front lifting member are composed of separate members, and the end of each lifting member isSaidThe rear lifting member and the front lifting member may be gathered at a lower position of the back body, and the rear lifting member and the front lifting member may be configured by the same member that continues from the back body, the crotch portion, and the front body. It may be.
[0014]
As described above, when the rear lifting member and the front lifting member are formed as separate members or the same member and exhibit a continuous lifting force from the back body through the crotch to the front body, the body fluid absorbent article can be reliably supported. .
[0015]
  MoreFurther, in the panty portion, when the elastic contraction force is compared between the portion where the rear lifting member and the front lifting member are provided and the portion adjacent to each lifting member and where the lifting member is not provided In addition, it is preferable that the elastic contraction force of the portion where each lifting member is provided is larger.
[0016]
With this configuration, when the panty part is stretched in the height direction and worn, the lifting force due to the extension of the lifting member and the rear lifting member is greater than the pressure applied by the extension of the panty part, and the crotch part It becomes possible to reliably support the body fluid absorbent article to be attached.
[0017]
  AlsoIt is preferable that at least a part of the exterior body is provided with a region having a higher heat retention function than other regions.
[0018]
For example, this region can be configured as a region in which a part of the panty part or the foot part is provided with a bulky cloth by pile processing or raising.
[0019]
By providing a region with a greater heat retention function than other regions, the heat retention effect can be enhanced to improve blood circulation by suppressing coldness of the lower abdomen, lower back or legs, and relieve lower abdominal pain and lower back pain during menstruation it can.
[0020]
Further, at least a part of the region may be formed of a cross-linked acrylate resin to which a polyvalent metal salt that generates heat by heat of hydration is added. In this case, the cross-linked acrylate resin has a moisture content of 20% or more in an environment where the temperature is 20 ° C. and the relative humidity is 65%.
[0021]
When the resin is provided, when moisture such as sweat from the body is absorbed, the charge of these polyvalent metal ions causes H₂So-called hydration in which O is strongly attracted occurs, a large amount of energy is released and heat is generated, and a heat retaining effect can be produced.
[0022]
  Also, the aboveCrotch fabricon the insideIs for wearing the body fluid absorbent articleAn attachment cloth is provided, and the attachment cloth may be configured such that a front end portion and a rear end portion are joined to the crotch fabric, and both side edges are not joined to the crotch fabric.
[0023]
If comprised in this way, by attaching a bodily fluid absorbent article to the said mounting | wearing cloth, the wearing of another short can be made unnecessary and the stuffiness by layering can be prevented.
[0025]
DETAILED DESCRIPTION OF THE INVENTION

Therefore, the gathering portion 23 has an arrangement structure in which the two front lifting members 21 and 22 are substantially branched from the rear lifting member 20.
[0037]
Both the rear lifting member 20 and the front lifting members 21 and 22 have elastic contraction force. Further, in this embodiment, the rear lifting member 20 and the front lifting members 21 and 22 are disposed substantially continuously from the back body 3B through the crotch 3C toward the front body 3A. Therefore, the contraction force exerted by the lifting member acts continuously from the back body of the panty part to the front body through the crotch part 3C, and the body fluid absorbent article can be reliably supported.
[0038]
The front lifting members 21 and 22 are arranged so that the interval gradually increases from the crotch 3C to the front body 3A starting from the gathering portion 23. In the crotch portion 3C, the front lifting members 21 and 22 are positioned with a gap L2 in the crotch width direction at a center line OO that is bisected in the front-rear direction. It is at a position separated by L1 rearward from the center line OO.
[0039]
The front lifting members 21 and 22 located in the crotch portion 3C exhibit a function of elastically pressing a sanitary napkin that is a body fluid absorbent article installed in the crotch portion. Since the dimension is 60 to 100 mm or less, the interval L2 is preferably shorter than the width of the sanitary napkin. Therefore, L2 needs to be 100 mm or less, preferably 60 mm or less. Moreover, since the crotch width of a crotch part of an adult woman is 20-40 mm, the more preferable range of said L2 is 20-40 mm.
[0040]
In order to set the distance L2 between the front lifting member 21 and the front lifting member 22 within the range of 20 to 40 mm at the center O of the crotch portion 3C, the gathering portion 23 and the center line OO The distance L1 is preferably in the range of 20 to 50 mm.
[0041]
Note that the terminal 20a of the front lifting member 20 and the terminals 21a and 22a of the rear lifting members 21 and 22 do not necessarily have to be continuous at the gathering portion 23, and the terminal 20a and the terminals 21a and 22a are You may leave | separate in the downward position of the back body 3B, or the back position of the crotch part 3C. Further, the terminal 20 b of the rear lifting member 20 and the terminals 21 b and 22 b of the front lifting members 21 and 22 may be located away from the waistband portion 2.
[0042]
The material constituting the pantyhose 1 is a combination of elastic yarn and nylon yarn, and the pantyhose 1 has elastic elasticity as a whole. The waist covering fabrics 10A and 10B of the panty part 3 are woven fabrics knitted by a single covered yarn. The single covered yarn is made of nylon yarn (24 pieces) around spandex (fineness 44 dtex) which is a polyurethane elastic yarn. And a fineness of 77 dtex) is wound in a single layer.
[0043]
The leg portion 4 is a woven fabric knitted by a double covered yarn, and the double covered yarn is made of nylon yarn (made of five filaments, fineness of 11 dtex) and nylon yarn around a spandex (fineness of 22 dtex). One of the five filaments (fineness is 16.5 dtex) is wound in a double direction while changing the direction so that the other is the upper twist and the other is the upper twist.
[0044]
The toe portion 5A and the heel portion 5B are made of a woven fabric knitted in mesh with a thread formed by wrapping a nylon thread (consisting of 17 filaments and a fineness of 55 dtex) around a spandex (fineness of 22 dtex). Thus, it is reinforced more than the other portions of the leg portion 4 and the foot portion 5.
[0045]
However, each material which comprises the pantyhose 1, the leg part 4, the toe part 5A, and the heel part 5B demonstrated above is not limited to these, It can also comprise with another suitable material.
[0046]
It is preferable that the rear lifting member 20 and the front lifting members 21 and 22 have an elastic contraction force. By having the elastic contraction force, the support force of the sanitary napkin is easily exhibited. For the rear lifting member 20 and the front lifting members 21 and 22, for example, bands formed of polyurethane, natural rubber, or synthetic rubber are preferably used.
[0047]
However, the rear lifting member 20 and the front lifting members 21 and 22 may be formed of a member having little elastic contraction force or a member having no elastic contraction force. In this case, the rear lifting member 20 and the front lifting members 21 and 22 have a length slightly shorter than the height when worn on the body. When the panty part 3 is attached to the body and the panty part is stretched in the body height direction, the rear lifting member 20 and the front lifting members 21 and 22 are in close contact with the buttocks, the abdomen, and the crotch part, and against sanitary napkins and the like Can demonstrate support.
[0048]
The rear lifting member 20 and the front lifting members 21 and 22 are preferably sewn to the inner surface of the panty portion 3. When stitched to the inner surface, a support force can be applied to the sanitary napkin more strongly than when stitched to the outer surface. Moreover, it can prevent that the shape of each said lifting member 20, 21 and 22 appears on the surface of the clothes worn on the outer surface of the said pantyhose 1, and can obtain a beautiful external appearance at the time of wear. However, in the present invention, the rear lifting member 20 and the front lifting members 21 and 22 may be sewn to the outer surface of the panty portion 3.
[0049]
The rear lifting member 20 and the front lifting members 21 and 22 preferably have a width of 5 to 20 mm. If the width dimension is less than 5 mm, the applied pressure of the front lifting members 21 and 22 is likely to act locally on the crotch portion to cause a feeling of pressure. In addition, the position of the front lifting members 21 and 22 relative to the crotch part becomes difficult to stabilize, and there is a possibility that the position where the support force acts on the sanitary napkin becomes unstable. The front lifting members 21 and 22 preferably have a function of pressing the central portion of the sanitary napkin against the crotch portion and deforming the central portion of the sanitary napkin into a convex shape so as to face the vaginal opening. When the width dimension of the members 21 and 22 is larger than 20 mm, it becomes difficult to exhibit the function.
[0050]
Since the rear lifting member 20 and the front lifting members 21 and 22 are bands having a flat cross section, a stable support force can be given to the sanitary napkin. However, the lifting members 20 and 21 and 22 may have a circular cross-sectional shape, and as shown in FIG. 4, the lifting members 20 and 21 and 22 are formed by zigzag zigzag stitching. It may be. In the case of the zigzag stitch, it is preferable that the distance W1 between the vertices in the width direction of the zigzag shape is 5 mm to 20 mm.
[0051]
The elastic contraction force in the direction in which the lifting members extend in the portions where the lifting members 20 and 21 and 22 are provided is the waist backing fabrics 10A and 10B in the portions where the lifting members are not provided. It is larger than the elastic contraction force in the height direction. For example, when the panty portion 3 is stretched in the body height direction at a stretch rate of 50%, the elastic contraction force F1 in the direction in which each lifting member extends in the portion where the lifting members 20 and 21, 22 are provided. F2 becomes larger than the elastic contraction force in the body height direction of the waist-supporting fabrics 10A and 10B at the portions where the lifting members are not provided.
[0052]
The elastic contraction force is measured as follows. A material in which a lifting member is sewn to the waist-supporting fabrics 10A and 10B is cut into a size of 150 mm in length and 25 mm in width. Both ends of the measurement sample in the vertical direction are held on the chuck of a Tensilon tester, the initial chuck distance is 100 mm, a tensile test is performed at a pulling speed of 100 mm / min, and the measurement sample is 1.5 times in the vertical direction. The load when stretched is taken as the measured value of the elastic contraction force F1, F2 of the portion where the lifting members 20, 21, 22 are provided. Further, a sample of the same size as that described above was formed using the waist-supporting fabric 10A or 10B as a vertical direction, and the values measured with a Tensilon tester were similarly used to determine the height-direction of the waist-supporting fabric 10A, 10B. The elastic contraction force.
[0053]
When the pantyhose 1 is used, a sanitary napkin is worn on the inner side of the crotch 3C of the shorts, and the pantyhose 1 is worn thereon. In the wearing state, the leg parts 4 and 4 have a slight elastic contraction force and are in close contact with the leg part of the body. In addition, the panty part 3 is in close contact with the abdomen and buttocks of the body, with the entire part extended in the width direction and the height direction. Due to the adhesive force of the panty part 4, a relatively weak pressing force acts on the abdomen and buttocks of the body, and the function of adjusting the body shape can be exhibited.
[0054]
When the panty part 4 is extended, the rear lifting member 20 exhibits an elastic contraction force F1 along the groove of the buttock in the back body 3B, and the two front lifting members 21 and 22 in the crotch part 3C and the front body 3A. However, it exerts elastic contraction forces F2 and F2 in the height direction. The elastic contraction forces F1 and F2 act so as to lift the crotch 3C, and in the crotch 3C, the two front lifting members 21 and 22 function to press the sanitary napkin at two locations against the crotch. . Therefore, the sanitary napkin is less likely to be displaced from the crotch portion, and it is easy to maintain a state of being in close contact with the vaginal opening.
[0055]
Moreover, when the width dimension of the said rear lifting member 20 and the front lifting members 21 and 22 exists in the range of 5-20 mm, it can prevent giving an excessive pressure to a wearer's lower abdominal part and a hip periphery.
[0056]
When the pantyhose 1 configured as described above is worn, the pantyhose 1 exhibits the support function of the sanitary napkin. Therefore, the shorts worn on the inner side may have a relatively weak pressure on the body. When the pantyhose 1 is worn repeatedly, it becomes difficult to inhibit the degree of freedom of movement of the body.
[0057]
The crotch portion 3C of the pantyhose 1 preferably has a liquid blocking function. When the liquid blocking function is provided, even when menstrual blood that has not been absorbed and held by the sanitary napkin flows from the shorts to the crotch portion 3C, the risk of soiling clothes and the like by menstrual blood is reduced. For example, the crotch fabric 13 forming the crotch portion 3C is configured by laminating a film having a moisture permeable function on a cloth formed by knitting polyester fibers.
[0058]
Further, a part of the panty part 3, the toe part 5A, 5A, the heel part 5B, 5B, or a part that abuts on the sole of the foot part 5 is formed of a cloth configured to be bulky by pile processing or raising process. Alternatively, the bulky cloth may be provided on the fabric constituting the panty portion 3. Since the bulky cloth can hold many air layers, the air layer warmed by the body temperature of the human body can be held on the bulky cloth. Therefore, by providing a bulky cloth, it is possible to enhance the heat retention effect and suppress the cooling of the lower abdomen, lower back, or feet to improve blood circulation and relieve lower abdominal pain and lower back pain during menstruation.
[0059]
Further, at least a part of the panty part 3 has a smaller heat consumption (kcal / m) than a material constituting the other part of the panty part 3 or another material constituting the leg part 4 or the foot part 5.²-A material having hr) may be used to enhance the heat retaining function. For example, you may form at least one part of the panty part 3 with the cloth | dough formed with the said raw material, or the cloth | dough which contains the said raw material in part. Or you may sew | sew the cloth | dough formed with the said raw material, or the cloth | dough which contains the said raw material in part on the inner side of the said waist | absorbing cloth 10A, 10B. The material having the heat retaining function is provided, for example, in a region below the broken lines 25 and 25 shown in FIG.
[0060]
When the material having a heat retaining function is used, the heat retaining effect can be enhanced, the lower abdomen and the lower back can be suppressed, and blood circulation can be improved. By improving blood circulation, it becomes possible to relieve lower abdominal pain and back pain, especially during menstruation.
[0061]
Examples of the material that consumes less heat include blended yarns in which cross-linked acrylate fibers and acrylic fibers are blended. As described above, at least a part of the panty portion 3 is formed of a fabric formed of the blended yarn or a fabric formed of the blended yarn and other fibers, or the fabric is superimposed on a fabric constituting the panty portion. Used.
[0062]
The blended yarn is composed of, for example, 30% by mass of the crosslinked acrylate fiber and 70% by mass of acrylic fiber, and the blended yarn has a fineness of 192 dtex.
[0063]
The resin forming the cross-linked acrylate fiber is acrylonitrile (CH₂= CH-CN) and a copolymer of methyl acrylate as a monomer. Other examples of the monomer include sulfonic acid-containing monomers such as vinyl halide, vinylidene halide, and p-styrene sulfonic acid, and salts thereof, carboxylic acid-containing monomers such as itaconic acid and salts thereof, acrylamide, styrene, and vinyl acetate. Etc. The resin forming the acrylic fiber forming the blended yarn is an addition polymer of acrylonitrile.
[0064]
The cross-linked acrylate fiber is made into a cross-linked type by hydrazine treatment of the acrylate and cross-linking nitrile groups (—CN). Hydrazine (NH₂-NH₂) Can be exemplified by hydrated hydrazine, hydrazine sulfate and the like.
[0065]
Further, a part of the nitrile group is a carboxyl group (—COOH), and the remaining nitrile group is an amide group (—CONH).₂This conversion treatment can be performed by inclusion of an aqueous base solution such as an alkali metal hydroxide or ammonia, or a strong acid. The crosslinked acrylate fiber has a pH adjusted to 4.0 to 7.0, and a part of the carboxyl group is selected from nitrates, hydrochlorides, and sulfates of polyvalent metals such as Ca, Mg, and Al. In addition, it is a metal salt to which one or more salts are added.
[0066]
The reason why the pH is adjusted to 4.0 to 7.0 is that a part of the carboxyl group is in a dissociated state, and the conversion into the metal salt is performed quickly and uniformly into the fiber.
[0067]
A chemical structure simply showing the cross-linked structure of the cross-linked acrylate resin is shown in Chemical Formula 1.
[0068]
[Chemical 1]

[0069]
Chemical formula 1 has main chains 42 and 43 formed by polymerization of acrylonitrile and other monomers, and these main chains are cross-linked by bridges A and B. The bridge A is a portion in which a nitrile group is cross-linked by hydrazine treatment. The bridge B is a portion in which a part converted to a carboxyl group is converted to a metal salt by a nitrate of the polyvalent metal M or the like.
[0070]
Since the cross-linked acrylate resin contains the polyvalent metal M, when moisture such as atmospheric moisture or sweat is absorbed by the acrylic fiber, the moisture is strongly attracted to the polyvalent metal ions, so-called water. A Japanese phenomenon occurs. Energy is released by this hydration and heat is generated, so that the heat retention effect is enhanced.
[0071]
Further, the above-mentioned cross-linked acrylate resin can obtain a moisture content of 20% or more in an environment where the temperature is 20 ° C. and the relative humidity is 65%. This moisturizing property also makes it easier to feel warmth on the skin.
[0072]
Furthermore, when a gas having an unpleasant pungent odor is generated, the deodorizing action by adjusting the pH of the crosslinked acrylate has a function of appropriately suppressing the gas from leaking out of the shorts. Occurrence of an annoying odor during menstruation can also be reduced.
[0073]
Moreover, you may form the said toe part 5A, 5A and the heel part 5B, 5B with the woven fabric containing the raw material which has the said heat retention function.
[0074]

Yes. In this example, since the elastic contraction forces F1 and F2 work only on the lower part of the waistbands 40A and 40B formed on the panty part 3, the feeling of pressure given to the wearer can be reduced. Further, since the waist bands 40A and 40B are in close contact with the vicinity of the position of the hipbone, the panty part 3 is unlikely to slide down even when the elastic contraction forces F1 and F2 are applied.
[0075]
Here, generally the length dimension of the vertical direction of a sanitary napkin is in the range of 160-400 mm. Therefore, the total length from the other terminal 20b of the rear lifting member 20 to the other terminal 21b or 22b of the front lifting member 21, 22 is preferably longer than 400 mm. When the length dimension is longer than 400 mm, the sanitary napkin is suitable for use at night or on days with a large amount of menstrual blood excretion, even when a sanitary napkin with a long longitudinal dimension is worn. It is possible to reliably support the vertical direction of the entire length.
