Description

TECHNICAL FIELD The present invention relates to a novel napped product and a method for producing the same.
More specifically, the present invention relates to a napped product having a stabbing / fluff two-layer structure, which is flexible and excellent in water repellency and stain resistance, and a method for producing the napped product.

Natural fur such as mink, fox, chinchilla has a complicated napped structure, is extremely soft and has a pleasant touch and repellent property, and is in a position as an expensive clothing material or a high-class fashion material.

[Problems to be Solved by Prior Art and Invention]

Heretofore, various methods have been proposed for imparting soft, slimy, antifouling properties and water repellency like natural fur using synthetic fibers.

For example, as an invention for improving the flexibility and the water repellency by adding a treatment agent containing a silicone resin as a main component to synthetic fibers or napped cloth, Japanese Patent Publication Nos. 48-17514, 51-2555 and 51555 -2556, JP-A-52-77229,
JP-B-51-37996, JP-B-61-9432, JP-A-57-199873, JP-B-60-54434 and the like. These technologies have made great progress by becoming animal hair-like compared to conventional ones, but they are still unsatisfactory compared to natural fur, and have a waxy slimy feeling peculiar to silicone, and further durable. It lacks water repellency and has the drawback of being extremely susceptible to stains.

On the other hand, as a durable water-repellent and antifouling treatment, see, for example,
55-76167 discloses a method of treating with a hydroxyl group- or carboxyl group-containing unsaturated monomer and a cross-linking agent after adding a fluorine-based water repellent treatment agent. JP-A-55-84477 discloses a fluorine resin and an epoxy compound. Have been proposed. However, although these methods improve both water repellency and durability, they have the drawback that they have a rough feel and are rough and hard, and are incomparable with natural fur.

As a method of improving this feeling of roughness and imparting flexibility and water repellency, for example, JP-A-54-55697 and JP-A-57-1.
Japanese Patent Publication No. 54466 and Japanese Examined Patent Publication No. 61-468 propose a method of treating by using a fluorine compound and a silicon compound in combination. Although such a method has a considerably improved softness, it is unsatisfactory as compared with natural fur, and particularly has a drawback that it lacks repulsion and has insufficient antifouling property.

In summary, (1) The one treated with a silicone treatment agent has a soft and repulsive property and a feel like animal hair, but has the disadvantage that it has a waxy slimy feel and is easily soiled. Have.

(2) Those treated with a fluorine-containing treatment agent have excellent water repellency and antifouling properties, but have the drawbacks of poor flexibility and repulsion, a dry feeling, and a rough texture.

(3) The one treated in combination with the silicon-based treatment agent and the fluorine-based treatment agent is halfway in that the characteristics and drawbacks of the above (1) and (2) are halved, and is more water repellent than natural fur. It has the drawback of insufficient stain resistance, flexibility, repulsion, and texture.

A first object of the present invention is to provide at least two naps in the longitudinal direction.
It is intended to provide a new napped product having a three-dimensional structure coated with different kinds of resins. A second object is to provide a napped product which has a texture and repulsion similar to those of natural fur and is durable and has excellent stain resistance and water repellency. A third object is to provide a method capable of industrially easily producing such a napped product.

[Means for solving problems]

The inventors of the present invention have made intensive studies to improve the above-mentioned problems of the prior art and obtain a napped product having a texture more closely resembling that of natural fur. As a result, a napped fabric consisting essentially of a stabbed / fluff two-layer structure. In the above, the silicone resin is attached to the lower layer portion (the lower layer portion of the fluff and the fluff layer) corresponding to the fluff length in the longitudinal direction of the napped fiber to impart flexibility, repulsion and a feeling of raised fluff to the upper layer portion ( A fluoric resin is attached as a main component to the upper part of the fluff above the fluff to eliminate the waxy slimy feeling, and to impart antifouling property and water repellency, thereby providing properties remarkably similar to natural fur. It has been found that a napped product with can be obtained and has reached the present invention.

That is, the present invention provides a napped fabric having a napped structure having at least two layers of napped-like napped hair having a napped length of 7 mm or more and fluff-like napped hair having a napped hair length of 3 mm or more, and the napped hair having a napped longitudinal direction. The napped product is characterized in that a silicon-based resin is attached to the lower layer portion corresponding to the fluff length and the fluorine-based resin is attached to the upper layer portion as a main component.

Further, in the method of the present invention, a silicon treatment agent is applied to a napped fabric having a napped structure of at least two layers of napped naps having a napped length of 7 mm or more and fluff napped hairs having a napped length of 3 mm or more. A method for producing a napped product, which comprises a first step of applying a centrifugal force after squeezing and a second step of applying a fluorine-based treatment agent to the upper layer portion of the prickly nap.

The napped fabric according to the present invention is a multi-layer napped structure including at least prickly napped fibers and fluff napped fibers, and has a specific nap length. That is, the stabbing hair length is 7 mm or more,
It consists of fluffy napped fibers that are 3 mm or more shorter than the napped length.
Stinging-like short hairs with a short hair length of less than 7 mm have insufficient coverage and poor texture because the napped hair is less likely to fall over and stands upright. Even if the napped hair is laid down at an appropriate angle, the effect of the present invention is not sufficiently exerted. In order to fully exert the effect of the present invention, the napped hair length is 7 mm or more, preferably 10 mm or more, more preferably 15 mm or more. The length of fluffy napped hair needs to be shorter than the length of stabbed napped hair by 3 mm or more, preferably 5 mm or more, more preferably 7 mm or more. When the difference in nap length is small as less than 3 mm, the effect of the present invention is sufficient because the adhesion layer of the fluorine-based resin attached to the fluff part above the fluff length (hereinafter also referred to as the upper layer part) is short as described below. I can't demonstrate. If the fluff length is too short, heat retention and elasticity are inferior, and as will be described later, it is not preferable because troubles in the manufacturing process, such as the silicon-based treating agent easily spattering and disappearing due to the action of centrifugal force, are not preferable. .
From this point of view, the length of fluffy nap is 4 mm or more, preferably 5 mm or more, more preferably 6 mm or more.

The napped fabric according to the present invention refers to a multi-layer napped structure comprising at least a napped nap group and a fluff nap group.
The fluff groups of fluff may be homogeneous, or a plurality of fluff fibers having different thickness, cross-sectional shape, nap length, nap density, fiber material, crimped state, etc. may be mixed. Good.

The base material, which is the fiber base material of the napped cloth according to the present invention, is natural fiber such as wool, silk, hemp, cotton, regenerated fiber such as rayon, cupra, suf, acetate, polyamide, polyester, polyetherester, polyacrylonitrile. Any of synthetic fibers such as polyolefin, vinyl-based polymer, polyurethane, etc. may be used. Among them, synthetic fibers that are easily processed, particularly polyester-based fibers are preferably used.

Further, the napped cloth may be in any form such as woven fabric, knitted fabric, non-woven fabric, resin-processed fabric, electrostatic flocking. Even in the manufacturing method of napped cloth, ordinary sliver knit method, raised method,
There are electrostatic flocking methods, knitting methods using a pile knitting machine, and weaving methods, but the methods are not limited to these methods, and can be appropriately selected depending on the purpose and application. Above all, the pile knitting and weaving methods are suitable for the present invention because a high-quality napped product can be obtained such that a design property can be intentionally imparted to the product and high-density flocking can be performed. In order to form a napped structure of a plurality of layers as in the present application, for example, a method of knitting and knitting by mixing and weaving stab-like short fibers and fluff-like short fibers whose both ends are sharpened into a pile system before being made into a pile knitted fabric in advance. Alternatively, a method in which a fluff-like long fiber and a fluff-like long fiber are combined, a pile fabric is knitted and woven, and then long hair / short hair is made and a tip is made thin by a chemical agent, for example, the present inventors have published a Japanese patent publication 59. It can be carried out by the method disclosed in Japanese Patent Publication No. 45788.

The napped product of the present invention is a napped fabric having a stabbed / fluff multilayer structure, and the lower layer part corresponding to the fluff length of the nap in the longitudinal direction of the nap has a silicon-based resin attached thereto, and the fluff is above the fluff. The pricked part has a three-dimensional structure to which a fluorine resin is attached as a main component.

The feature of the present invention is that different resins are attached in the length direction of the naps in this way, and therefore, a synergistic effect is exerted and the drawbacks are complemented. That is, the lower layer mainly composed of fluffy napped hair is rich in flexibility, repulsion and slipperiness between fibers, and the upper layer of stabbed napped hair has no waxy slimy feel and is water repellent and stain resistant. It is composed of abundant materials, and the texture and characteristics of a napped product cannot be obtained at all when they are adhered individually or in a mixed state.

1 and 2 are schematic cross-sectional views of pile fabrics showing specific examples of the product of the present invention. In the figure, (1) is thick, long, relatively small number of finely tipped fluffs, (2) is thin, short, relatively large number of crimped fluffs, and (3) is stylus fiber. And a fluff fiber are bundled, and (4) and (5) are ground yarns. Fig. 1 shows an example of napped hair in which the fluff and fluff co-hair lengths are relatively balanced. (A) is the lower layer portion of the napped fiber corresponding to the fluffy napped hair length, and (B) is the upper layer portion of the napped fiber. , (C) are boundaries between upper and lower layers. Fig. 2 shows an example of napped hair in which napped lengths of stabbing and fluff are distributed. The lower layer part (A) of the napped fiber is the distance from the average napped length of the fluff to the base cloth, and the boundary layer (C) is the width. Is a wide example. Therefore, in the boundary layer (C), the silicon resin and the fluorine resin are mixed. The boundary layer (C) is 0.1 to 5 mm, although it varies depending on the napped morphology, treatment conditions, etc., and is in the range of 1 to 3 mm in most cases.

In the napped product of the present invention, the silicone resin is attached to the lower layer portion (A) of the napped fiber, and the fluorine resin as the main component is attached to the upper layer portion (B). Examples of the silicone resin in the present invention include, but are not limited to, dimethylpolysiloxane, dimethylhydrogenpolysiloxysan, epoxy-modified silicone, amino-modified silicone, phosphoric acid-modified silicone, and carboxylic acid-modified silicone. However, the main component was selected from at least one of epoxy-modified silicon, amino-modified silicon, and phosphoric acid-modified silicon as a material having excellent durability and exhibiting a significant synergistic effect with the fluorine-based resin. Modified silicone is preferred. As the modified silicon, aminosiloxane, epoxysiloxane, and phosphoric acid ester siloxane having the following repeating units are preferable.

However, R is a lower alkyl or aryl group, A is an alkylene group having 2 to 5 carbon atoms, an arylene group having 6 to 10 carbon atoms or an arylene group having a substituent, (R 'is hydrogen, a lower alkyl or aryl group, R "is a lower alkyl or aryl group.) When X is -NH-R', R'and A are more than one aromatic ring or a direct bond. Polyorganosiloxane containing at least two of these epoxy groups, amino groups and phosphoric acid ester groups in one molecule is preferably used for the modified silicone.

The silicone resin adheres to the lower layer of the napped fibers, and the amount of adhesion is preferably 0.1 to 10% (based on the weight of the fiber), more preferably 0.2 to 8%, most preferably 0.3 to 5%. If the adhesion amount is less than 0.1%, no remarkable effect is observed. On the contrary, if it exceeds 10%, the effect is saturated, and on the contrary, the resin may drop off due to adhesion between fibers or friction, which is not preferable.

Examples of the fluorine-based resin in the present invention include polymers of vinyl-based compounds containing at least the compound represented by the following general formula (III).

(In the above formula, R is hydrogen or an alkyl group having 1 to 4 carbon atoms, Y
Is a group containing an alkylene group having 1 to 6 carbon atoms, and n is 1 to
Represents an integer of 30. ) Polymers composed of these fluorine compounds are known, and those commercially available from many manufacturers can be used.

In the present invention, the fluorinated resin is adhered to the upper layer portion of the napped fiber, but the adhesion amount is preferably 0.1 to 10% (based on the weight of the fiber), more preferably 0.2 to 8%, and 0.3 to 5%.
Is most preferred. If the adhered amount is less than 0.1%, no remarkable water repellency and antifouling effect is observed. On the other hand, if the amount of adhesion exceeds 10%, the water repellency and antifouling effect will be saturated, and conversely, the resin will fall off due to adhesion between fibers or friction, or the rough texture will be greatly impaired. This may cause spots, which is not preferable. As a resin other than the fluorine-based resin, a small amount of the above-mentioned silicon-based resin may be mixed in the upper layer portion of the napped fiber. However, the fluorine-based resin must account for at least 50%, preferably 60% or more, based on the total weight of the resin deposited on the upper layers of the napped fibers. If the adherence ratio of the fluorine-based resin is less than 50%, the antifouling property is deteriorated, which is not preferable. The boundary layer (C) between the upper layer portion (B) and the lower layer portion (A) of the napped fiber is not limited to this, and the ratio of fluorine resin: silicon resin is 100: 0 to 0: 100.
May be distributed in. The boundary layer (C) is within several mm at most, though it varies depending on the napped structure and substantially corresponds to the boundary line, so that the layer does not inhibit the effect of the present invention.

 Next, the manufacturing method of the present invention will be described.

The principle of the method for obtaining a napped product in which different resins are adhered to the upper layer portion and the lower layer portion in the napped fiber longitudinal direction of the napped fiber of the present invention is as follows: thick, small surface area and coarse napped hair with a napped density,
Utilizing the difference in liquid retaining ability between thinly crimped fluff with a large surface area and dense nap density, centrifugal force acts to cause a difference in adhesion of the treatment liquid to the fluff layer and the upper layer of the prickle And a second step in which different treatment liquids are applied to the upper layer portion of the bristles. As the processing method of the first step,
The inventors of the present invention have disclosed Japanese Patent Publication No. 59-45788, Japanese Patent Publication No. 59-43580.
The method using the centrifugal processing machine presented in the publication is extremely suitable, but the method is not limited to this. The processing method in the second step may be any of the method using the centrifugal processing machine, the spray method for applying mist-like droplets, the method for applying in the form of foam, the applying method such as a printing machine, etc. Good. Furthermore, the inventors of the present invention set out the first step and the second step.
Alternatively, the centrifugal processing machine as presented in Japanese Patent Publication No. 40951 can be used. Also, a method of performing the first and second steps in reverse can be adopted in some cases. That is, the manufacturing method of the present invention includes all methods that utilize centrifugal force in at least one of the first and second steps. Above all, a method of applying a centrifugal force in the first step and then treating the upper layer portion of the napped fibers with a different treatment agent in the second step is preferably used.

FIG. 3 is a schematic view of a centrifugal processing machine suitable for the method for producing a napped product of the present invention. In the figure, (6) is the rotation axis,
(7) A rotating body (inner cylinder) that rotates together with the rotating shaft, (8)
Is a napped fabric attached to the rotating body, (9) is a processing liquid having a liquid surface formed by centrifugal force, and (10) is a container (outer cylinder) for containing the processing liquid rotating with the rotating body. For example, the treatment liquid (9) is a silicone treatment liquid, and the liquid is discharged to the root of the napped hair (or the position where the base cloth is immersed) while rotating, and then the liquid is drained to sufficiently retain the fluff layer, but the sting layer scatters. After applying a centrifugal force, the liquid is drained and then heated from the outside of the container (10) to form a resin coating on the lower layer of the napped fibers. Next, a fluorinated treatment agent liquid having a slightly increased viscosity is supplied and applied to the upper layer portion of the napped fibers, then the liquid is drained, followed by drying and heat treatment.

As another example, the container of (10) is separated from the rotating shaft by a clutch to form a non-rotating body, and the silicon treatment liquid (9) is attached to the rotating body (7) in the container (10). )
Is put into a position where one end of the fabric is completely immersed, and then the rotator (7) is rotated at a low speed to immerse the whole napped fabric (8) and then discharged. Next, increase the rotation speed of the rotating body (7), for example, apply a centrifugal force of 30 G to the naps for 3 minutes, stop the rotation, take out the napped cloth, and dry it at 80 ° C for 1 hour.
It is treated at 160 ° C. for 5 minutes to form a resin film. Then, the fluorine-based treatment liquid is sprayed onto the upper layer portion of the naps from an angle of 45 °, dried and heat-treated.

The treatment liquid may be a drainage system or an aqueous emulsion, and can be appropriately selected.

It is desirable to perform a heat treatment (curing) in order to firmly adhere the silicon-based and fluorine-based resin coating to the fiber surface, but the present invention is not particularly limited to such treatment. When the curing temperature is usually 100 ° C. or lower, long-term treatment may be required, resulting in lack of productivity, or insufficient resin film forming property, resulting in resin dropout or unfavorable results. . Further, if it exceeds 230 ° C, the napped fabric may be damaged, or may cause color burning or shrinkage or fusion, so a more preferable curing temperature is 100 to 230 ° C, and particularly 130 to 200 ° C is most preferable. . The curing time is the curing temperature,
Although it depends on the catalyst and the like, it may be any time as long as the resin film is sufficiently formed. Usually, if it is 10 seconds or more, a sufficiently strong resin film is formed. Even if the treatment is carried out for a too long time, not only the resin film forming property is saturated, but also problems such as inferior productivity and energy cost may occur. Therefore, a suitable treatment time is 10 seconds to 30 minutes, more preferably 1 to 20 minutes.

The napped product of the present invention is not particularly limited with respect to the density of the napped fiber, but in order to further exert the characteristic effects of the present invention such as feeling, repulsion and durability, the napped density is
3,000-100,000 lines / cm ² is preferable, 5,000-30,000 lines / cm
² is more preferable. Piloerection density of sting is preferably 50 to 5,000 present / cm ^2, more preferably from 100 to 1,000 present / cm ^2, also nap density of the fluff is preferably 1,000 to 50,000 present / cm ^2, 5,000 to
The product of 30,000 fibers / cm ² is particularly preferably used because it gives a product having a texture, luster, a feeling of softness, resilience, elasticity and durability that is very similar to natural fur.

The single yarn fineness of the prickly fiber suitable for the napped product of the present invention is 10
-100d is preferable, 15-80d is more preferable, and it is suitable for the present invention. If the fineness is less than 10d, the effect of stinging is poor, and conversely, if the fineness is 100d or more, it is too thick and coarse and hard. The stabbed fibers may be crimped, but slip,
In terms of gloss and appearance, it is often preferable to use a substantially straight product. The cross section of the stinging fiber may be a round cross section, but a modified cross section is preferable in terms of covering property, appropriate rigidity, adhesion of treatment agent, apparent thickness, etc. A flat modified cross section or the like is particularly suitable.

The fluffy fiber preferably has a single yarn fineness of 0.1 to 4d, and 1 to 3d.
More preferred are those suitable for the present invention. Fineness 0.1d
If the amount is less than 1, the bulkiness and repulsion are poor, which is not preferable. On the other hand, if the fineness exceeds 4d, the soft feeling as a fluffy texture is lost and coarse hardness is not preferable. The fluffy fibers may be substantially straight, but are crimped in order to impart resilience, bulkiness, heat retention, covering property of the base cloth, etc. and to make it easy to take in the silicone-based treating agent. Is often preferred. If the crimp is too strong, unfavorable phenomena such as yarn entanglement and poor openability may occur. Therefore, the crimp strength is in a suitable range. For example, the number of crimps (the number of peaks under a tension of 1 mg / d) is 2 to 30 pcs / 25 mm, more preferably 3 to 20 pcs / 25 mm, and the crimp elongation rate is 30%.
Below, more preferably 20% or less, especially 3 to 15% is suitable for the present invention.

Here, the crimp elongation rate is determined by the formula (I) and is 20 ° C and 65%.
Measure at RH room temperature.

However, l ₀ : sample length when load is 2 mg / d (cm) l: sample length after 2 minutes when load is 50 mg / d (cm) When the sample is pile yarn (continuous filament), approx. 1000 denier, 30 cm long bundle, 100 with no load
Measure 20 times in water at ℃ for 20 minutes and air-dry at 20 ℃, 65% RH for 24 hours, and obtain the average value. If the sample is a short fluff cut from a napped product, it should be as long as possible (for example, a sample length of 5 to 50 mm)
Using, to make a bundle of about 50 denier, measure 20 times and obtain the average value.

In the napped product of the present invention, the base fabric may be any of knitted fabric, woven fabric, non-woven fabric, etc., but is not limited thereto.
A knitted fabric or a woven fabric is preferable for producing a high-density, high-quality napped product. Examples of fibers used for the base cloth include synthetic fibers, semi-synthetic fibers, and natural fibers, but any material may be used. However, when properties such as heat resistance, flame retardancy and chemical resistance are required, thermoplastic synthetic fibers such as polyester fibers, aromatic polyamide fibers, flame retardant acrylic fibers are suitable. The fibers used for the ground yarn may be spun yarn made of staple or multifilament yarn, and may be selected according to the intended use.

In the napped product of the present invention, a known polymer elastic material is applied (backing) to the back surface of the base fabric on which the napped hair is planted.
It is preferable to do so, because hair loss of the napped hair can be prevented. It is useful to mix a flame retardant, a pigment, a dye, carbon powder, carbon fiber or the like with the backing agent depending on the application.

〔The invention's effect〕

 Next, the effects of the present invention will be summarized.

(1) The texture is very similar to that of natural animal hair. That is, compared to a silicone resin and a fluorine resin individually adhered or mixed and adhered, a wax-like slimy feeling is less and an appropriate slimy feeling like natural animal hair is obtained.

(2) The upper layer of prickly hair, which is the guard hair of a napped product, is covered with a resin film that is highly antifouling and water-repellent, and the lower layer of napped is covered with a resin that is repellent and has a small inter-fiber friction coefficient. A synergistic effect due to the formation of resin coatings having different characteristics in the longitudinal direction and further characteristic effects can be exhibited.

(3) The durability is remarkably improved. Withstands processes such as dyeing, home laundry and dry cleaning.

The napped product of the present invention is superior to natural fur products, and includes cold-prevention clothing, clothing, fashion materials, interior materials,
It is extremely useful as a material for dolls and stuffed animals.

Next, this S ₁ was spun to obtain a 60th count twine. This spun yarn was designated as Y ₂ and used as the ground yarn.

After warping the pile yarn FY ₁ and the base yarn Y ₂ , respectively, using a double pile loom, weaving with a pile length of 60 mm, and then cutting the pile yarn with a cutter, a pile fabric CP ₁ with a pile length of 30 mm CP ₁
I got CP ₁ was a napped density of about 10,000 filaments / cm ² W type flocked cloth.

This CP ₁ was attached to the centrifugal processing machine disclosed in Japanese Examined Patent Publication No. 59-45788 and subjected to fluff cutting and stinging. That is, the pile cloth CP ₁ was attached to a cylinder (inner cylinder) having a diameter of 1 m and a width of 1.5 m (fixed with a surface fastener disclosed in Japanese Patent Publication No. 60-7749), the lid was tightened, and the rotation speed was 500 rpm (centrifugal force of about 140 G). In the state where the napped hair is raised by centrifugal force by rotating with a centrifugal force, a treatment liquid at a temperature of 98 ° C and a 15% NaOH aqueous solution is rotated at the same speed as the inner cylinder. Is supplied from the base cloth to a point of 11 mm, and is heated from the outside of the outer cylinder with infrared rays in a non-contact system for 7 minutes while keeping the inside temperature of the processing liquid constant, and the fluff (Y ₁ ) is 11 mm from the base cloth. It was dissolved (decomposed) and cut so that it became long. Then, the treatment solution is discharged to the outside of the system, and the second accelerator is used as a second accelerator, which is a decomposition accelerator, neokatin G.

Next, a polyurethane-based backing agent was applied onto the back surface of the base cloth of this cloth so that the solid content was 12%, and dried to fix the nap and the base cloth. This napped fabric thus obtained is designated as FP ₁ .

Next, the above napped fabric FP ₁ was attached to a centrifugal machine and slowly rotated at 8 rpm (under low centrifugal force that does not form a liquid surface), while the amino-modified silicon concentration was 1% (solid content) in the outer cylinder container.
The emulsion aqueous solution of ( ₁ ) was supplied to a position where the base fabric of the napped fabric FP ₁ was sufficiently immersed, and the whole napped fabric FP ₁ was immersed by rotating for 5 minutes, and then the treatment liquid was discharged out of the system. Then turn

Then, it was dried from the outer cylinder under the same rotation while being heated by an infrared heater while being heated, and after being cured at a temperature of 150 ° C. for 10 minutes, the rotation was stopped and the napped cloth was taken out. The primary treated napped fabric had a weight gain of 0.8%. In terms of the feel of the hand, the fluff portion showed a very soft texture with a slimy feel, but the prickly portion (the portion longer than the fluff length of the fluff) did not have the slimy feel peculiar to silicone.

Then, the primary treated napped fabric is hung, and a 1.0% emulsion aqueous solution of Asahi Guard AG700 is sprayed as a fluorine-based treating agent from an angle of 45 ° to the upper part of the napped nap (the part above the fluff length of fluff) to give a solid content. Spray uniformly to about 0.8% (weight of fiber against upper layer of stabbing hair), then 120 ° C after drying.
Was heat-treated for 10 minutes. This treated cloth was passed through a brushing machine three times to open the fluff, and then a pattern was applied between hot rollers so that the nap angle was about 45 ° to obtain artificial fur ZP ₁ .

Comparative Example 1 The napped fabric FP ₁ obtained in Example 1 was dipped in the amino-modified silicone treatment liquid used in Example 1 to give a solid content deposition amount.
Squeeze with mangle to 0.8% and dry at 150 ℃
Heat treated for 10 minutes. Then, cotton opening and patterning treatment were carried out in the same manner as in Example 1 to obtain artificial fur ZP ₂ .

Comparative Example 2 The napped fabric FP ₁ obtained in Example 1 was dipped in the aqueous solution of the fluorine-containing treatment agent used in the second step of Example 1, squeezed with a mangle to 0.8%, and then dried at 120 ° C. And heat treated for 5 minutes. Then, cotton opening and patterning were performed in the same manner as in Example 1 to obtain artificial fur ZP ₃ .

Comparative Example 3 The napped fabric FP ₁ obtained in Example 1 was mixed with the amino-modified silicone used in Example 1 in a 1: 2 mixed solution, and treated in the same manner as in Comparative Example 1, and artificial Got the fur ZP ₄ .

The performance evaluation of the artificial furs obtained in the above Example 1 and Comparative Examples 1 to 3 was measured, and the results are shown in Table 1.

The water repellency was based on JIS L1092-5.2 (spray test). Dry cleaning is JIS L1018-5 ・ 36 ・ 2 ・
According to the E-2 method. The stain test is performed according to JIS L1021-6.17, and the contamination is measured according to JIS L1021-6.17.2.
It was judged by the gray scale of (2).

Artificial fur treated with only the silicon-based treatment agent of Comparative Example 1
The texture of ZP ₂ was relatively good, but it was easy to get dirty and was hard to remove. The artificial fur ZP ₃ treated with only the fluorine-containing treatment agent of Comparative Example 2 had excellent antifouling properties, but had a strong feeling of creaking and was far from the feel of natural mink. Further, the combination of the silicon-based treatment agent and the fluorine-based treatment agent of Comparative Example 3 had insufficient texture and stain resistance, but the product ZP _{1 of the} present invention had a proper texture and stain resistance. Was also excellent.

Examples 2 to 4 When the napped fabric CP ₁ obtained in Example 1 was subjected to an alkaline processing by a centrifugal machine, the amount of the processing liquid was changed to change the fluff and napped hair lengths, give various napped treated fabric FP ₂ ~FP _6.

According to Example 1, the napped fabrics FP _{2 to} FP ₆ were treated with a silicon-based treatment agent for the lower layer portion (A) of the napped hair and a fluorine-based treatment agent for the napped upper layer portion (B) of the artificial fur. ZP _{5 to} ZP ₉ were obtained.

The napped product was tested for antifouling property, water repellency, and feel, and the results are shown in Table 2.

As is clear from Table 2, ZP _{9 with} a nap length of less than 7 mm has a markedly rough texture and lacks bulkiness, and ZP ₇ has a nap length difference of 3 mm between the fluff and fluff. Those with less than 5 were lacking in covering property of the stabbing hair, and thus were insufficient in antifouling property and feeling. On the other hand, the product of the present invention had a texture extremely similar to that of natural mink, and was excellent in water repellency and antifouling property.

With raised fabric FP ₁ obtained in Example 5-7 Example 1 is prepared analogously to Example 1, except changing the treatment agent deposition amount, the artificial fur ZP ₁₀ ~
I got ZP ₁₄ .

The characteristics of this napped product were evaluated and the results are shown in Table 3. In addition, the composition of resin attachment of the napped upper layer (B) is
Was measured by X-ray fluorescence and F was measured by a chemical analysis method.

As is clear from Table 3, ZP ₁₈ in which the resin adhered to the napped upper layer (B) is less than 50% fluorine-based has insufficient water repellency and antifouling property, and the fluorine-based ZP ₁₄ , which had a deposition amount of less than 0.1% even at a ratio of 50% or more, was also inferior in water repellency, antifouling property and feeling. On the other hand, the products of the present invention were all excellent in water repellency and antifouling property and had a texture similar to that of natural mink.
