Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a raised product having an animal hair-like texture. Regarding the product.

(Conventional technology) Natural fur such as mink, fox, chinchilla, noodle fur, beaver, etc. is extremely flexible, has a pleasant texture and a complex raised structure, and is rich in luster and elasticity, making it an expensive clothing material and high-end fashion material. It holds an unwavering position as

Conventionally, various methods have been proposed for artificially imparting soft, slimy properties similar to natural animal hair to synthetic fibers.

For example, Japanese Patent Publications No. 48-17514, Japanese Patent Publications No. 51-2555, and Japanese Patent Publications No. 51-2556 disclose that synthetic fibers are treated with a treatment agent mainly composed of silicone resin to improve their durability and flexibility. Publication, JP-A-52-7722
9, JP 60-54484, JP 58
It is described in JP-A-144179, JP-A-57-199878, JP-A-55-122022, and the like.

These technologies have significantly improved the ability to create animal hair-like fleas compared to conventional ones.

However, these proposed methods are still unsatisfactory and have a number of drawbacks as follows.

b) The coefficient of friction of synthetic fibers treated with silicone-based treatment agents is much lower than that of untreated fibers, and although they are more flexible, they are not as effective as natural animal hair.

In either case, products whose texture has been improved by using silicone or a combination of silicone and polyurethane have a wax-like, slimy texture that is unique to silicone, and the slimy texture that is unique to natural animal hair. It lacks sex and luxury.

c) The effectiveness decreases due to dyeing or washing. When a hardening agent is added to improve durability, the treatment liquid becomes unstable, and problems such as adhesion between fibers and rough hardness tend to occur.

The inventors of the present invention have conducted extensive research in order to improve the conventional drawbacks and obtain a product that has a texture that closely resembles natural animal hair. The present invention was completed by successfully obtaining a durable product.

(Problems to be Solved by the Invention) The first object of the present invention is to provide a durable napped product that has a soft and excellent texture that closely resembles natural animal hair. Furthermore, it is an object of the present invention to provide a raised product that can be easily manufactured from ultra-high-grade fashion materials on an industrial scale.

(Means for Solving the Problems) The present invention provides at least the following substances A and B to a fabric made of synthetic fibers having a nap of 5 mm or more.
This relates to a raised product having an animal hair-like texture in which both substances are mixed and adhered at a ratio of 1 to 2/8 (weight ratio) and 0.1 to 7 weight (to fiber).

A: Polyorganosiloxane containing at least two phosphate groups in one molecule; B: Polyorganosiloxane containing at least two amino groups in one molecule.

The polyorganosiloxane containing a phosphoric acid ester group, which is the substance (A) applied in the present invention, has a main chain molecular acid of usually 500 or more, preferably 1000 or more, and usually has a carbon number of 1 to 20 carbon atoms. It is substituted with hydrogen groups, preferably mainly with methyl groups.

Further, the phosphoric acid ester group is bonded to the silicon atom through at least a carbon atom, and is represented by, for example, the one represented by the IF formula (1).

[R1: hydrocarbon chain, R2, R3: H or alkyl group, allyl group] The polyorganosiloxane containing a phosphate group applied to the present invention may also contain a 18iOH group or an alkoxy group as a reactive group. Included.

- The amino group-containing polyorganosiloxane of the sword material (B) has a main chain molecular weight of usually 500 or more, preferably 1
000 or more and is preferably substituted with a hydrocarbon group having 1 to 20 carbon atoms, preferably mainly a methyl group. The terminal amino group may be bonded to a silicon atom through at least a carbon atom, and the hydrogen atom may be substituted with an alkyl group, as represented by the following formula.

(R4, R5: hydrocarbon chain, R6, R7: H or alkyl group, n: 0 or 1) This polyorganosiloxane containing a terminal amino group also includes those containing a -5iOH group or an alkoxy group as a reactive group.

When the silicone-based material fAL (B) mentioned above is used individually, it undergoes a self-crosslinking reaction by drying or heat treatment, forming an elastic resin film, which is more elastic than ordinary polyorganosiloxane oils. A product with an animal hair-like texture that is repellent and durable can be obtained. However, according to the results of studies conducted by the present inventors, the elasticity, repellency, and texture are insufficient compared to natural animal hair. That is, substance (B) has an excessively strong waxy slimy feel peculiar to silicone. In addition, substance +A) does not have a wax-like slimy feeling, but has a slight squeak and lacks the sliminess similar to natural animal hair. Fourth, they all have insufficient elasticity and repulsion, and also have the disadvantage of gradually falling off in terms of durability.

Surprisingly, the present inventors discovered that by combining silicon-based materials (N and (Bl), which were insufficient when used alone, and by mixing both materials in a certain ratio, a synergistic effect was exerted. It was found that the disadvantages of each were covered and the durability was significantly improved.The reason for this is not clear, but the phosphorus contained in each of the substances A and B attached, adsorbed or chemically bonded to the nap fabric was found to be It is presumed that this is because the acid ester component and some of the 7-mino groups form an ionic bond or a phosphoric acid amide bond, resulting in a crosslinked form and polymerization.

In the present invention, the blending ratio of silicone-based substances A and B is, as a solid content, A/B = 9/1 to 2/8 (weight ratio), preferably 8/2 to 3/7, more preferably 7/3 to It is 4/6. If it is out of these ranges, the effects of the combined use, ie, the effects of improving animal hair-like texture, repellency, and durability, will not be sufficiently exhibited.

The amount of the treatment agent attached to at least the napped fibers of the napped fabric is 0.1 to 7% by weight, preferably 0.15 to 7% by weight.
It is 5% by weight. If it is less than 0.1% by weight, a slimy texture similar to animal hair cannot be obtained, and if it exceeds 7% by weight, not only the improvement effect will be saturated, but also disadvantages such as adhesion between fibers may occur. Undesirable.

Even if a small amount of other silicone substances, polyurethane, antistatic agents, etc. are mixed in the raised fabric, there is no problem as long as the requirements of the present invention are satisfied. For example, other silicone materials include epoxy group-containing polyorganosiloxanes and hydrogen polyorganosiloxanes, which may be preferred as they further improve elasticity, repulsion, and durability depending on selection. However, if the amount is too large, the effects of the present invention are often inhibited, and the amount of adhesion is preferably 8% by weight or less, preferably 2% by weight or less.

The raised synthetic fibers of the present invention are not particularly limited, and include polyamide fibers such as nylon 6.66 and copolymers mainly composed of these, polyethylene terephthalate,
Examples include polyester fibers such as polybutylene terephthalate and copolymers mainly composed of these, acrylic fibers, modacrylic fibers, polyolefin fibers, and vinyl fibers. Among these, polyester fiber is the most suitable material because it can be hydrolyzed with an alkali treatment agent and can be easily processed to make the napped tip thinner.

These synthetic fibers may contain a small amount of various conventionally known additives, such as titanium oxide, silicon oxide, and inert fine particles such as recombinants.

The napped product of the present invention has a napped part consisting of synthetic fibers of at least 5 mm. When the nap length is less than 5 mm1, the nap is difficult to fall down and stands upright, so the texture becomes rough and hard and the effect of the present invention is not exhibited. The nap length is 5 mm or more, preferably 10 mm or more, more preferably 15 mm or more,
This produces a remarkable effect. The piloerection length in this case refers to the maximum piloerection length (in the case of random hair transplantation, the mean value). For example, when it consists of a zigzag-like nape and a fluff-style piloe that is shorter than that piloe, it refers to the longest zigzag-style nape length.

The raised fabric used in the present invention may be produced by the usual sliver knitting method, raising method, electrostatic flocking method, or knitting or weaving method using a pile knitting loom, but is not limited to these methods, and may be used depending on the purpose and application. (These methods can be selected as appropriate. However, among these methods, pile face stitching and weaving methods are suitable for the present invention because they can provide a product with a planned design and can achieve high-density flocking, resulting in a high M product. be.

The napped product of the present invention may have a napped form (it is not particularly limited to this). For example, it may have a single napped length, or it may have a mixture of different napped lengths. Even if the napped fibers have the same t & degree, those with different finenesses may be mixed.That is, the present invention includes those made only of prickly WMk fibers and those made only of fluffy napped fibers. However, if you want a texture similar to natural fur, especially mink, it is preferable to use a fabric with a multilayered structure in which the raised structure consists essentially of prickly fibers and downy fibers. Hair - the tip of the piloerection fiber,
Those that are differentiated are preferred because they exhibit more of the effects of the present invention.

In order to create this 4j multi-layered raised structure, for example, in advance,
Before rubbing the pinon knitted fabric, pile yarn (Kol1ij) A method of knitting and weaving by blending and blending prickly-like long fibers and fluff-like short fibers, or knitting and weaving of prickly-like long fibers and fluff-like short fibers. After doubling the fibers and knitting and weaving the pile height, the present inventors have disclosed a method of applying a cross-linking agent ζ to make the hair longer/shorter or to make the tip thinner. This can be done by the method disclosed.

In the case of a multi-layer structure, the single yarn fineness of the bristle-like fiber is preferably 10 d to 100 d, more preferably 15 to 80 d.
0d, which is suitable for the present invention.

If the fineness is less than 10d, the effect as stinging hair is poor,
On the other hand, if it exceeds 100d, it indicates an axis direction that is too thick and coarse. The bristle-like fibers may be crimped, but they may not be smooth, shiny,
In terms of appearance, a straight-shaped one is often preferable. Further, the cross section of the fibers may be round, but from the viewpoints of covering properties, appropriate rigidity, adhesion of processing agents, apparent thickness, etc., irregular cross sections are preferable. Irregular cross-sections, etc., make the present invention suitable.

The fluff-like fiber preferably has a single yarn fineness of 0.1 to 5 d.

More preferably, those having 1 to 3 d are suitable for the present invention. Those with a fineness of less than 0.1 d tend to lack bulk and resilience. On the other hand, when the rutting degree is 5d, the soft feel of the fluffy texture tends to be lost and it tends to become rough and hard. The fluff-like fibers may be substantially straight, but may have repellency, bulk,
Since undesirable phenomena such as loss of heat retention and base fabric covering properties may occur, there is a suitable range for the crimp strength of 3. For example, the number of turns (the number of ridges under 1 mfld of tension) is usually 2 to 80 g/25 mm, preferably 3 to 80 g/25 mm.
20pcs/25mm Rf+ elongation rate is 80% or less,
Preferably 20% or less, especially 3 to 15% is suitable for the present invention.

Here, the crimp/stretch rate is determined by the formula (II, 20°b, where l: sample length (cm) at load 2mf/d) l: load 5
Sample length (cm) 2 minutes after applying 0 mf/d If the sample is yarn for pile (continuous filament),
A bundle of approximately 1,000 denier and 80 cm in length was processed in water at 20'C for 20 minutes without any load, and then heated at 20'C.
After air drying for 24 hours in 65% REI air, 2011g1 was measured and the average value was determined.

If the sample is short fluff cut from a nap product, use the longest possible fluff (for example, sample length of about 5 to 50 mm), make a bundle of about 50 denier, measure it 20 times, and find the average value.

In the napped product of the present invention, the base fabric may be any fabric such as knitted fabric, woven fabric, non-woven fabric, etc., and is not limited to it, but is preferably a knitted fabric or woven fabric. Adopted. The fibers used for the base fabric include synthetic fibers, semi-synthetic fibers, natural fibers, etc., but any leaf material may be used. However, if properties such as heat resistance, flame retardance, and chemical resistance are required, for example, polyester-based
Thermoplastic synthetic fibers such as aromatic polyamide fibers and flame-retardant acrylic fibers are suitable. The fiber used for the ground yarn may be a stable spun yarn or a multifilament yarn, and may be selected depending on the intended use.

In the napped product of the present invention, the back side of the base fabric on which the napped hair is flocked does not need to be coated with anything, but it is better to apply (backing) a known polymeric elastic material to prevent the napped hair from falling out. It's good to be able to do it. The backing agent may contain pigments, dyes,
Alternatively, it may be useful to mix carbon powder, carbon fiber, etc. depending on the application.

The napped product of the present invention is made by adhering silicone substances A and B to a napped fabric, but the method and step of applying them are not limited, and various conventional methods can be employed. The step of applying it may be before or after dyeing, or may be applied to pile yarn. For example, as a method of giving
A method of dipping the raised fabric in a treatment bath and squeezing it with a mangle, or a method of spraying and adhering it in the form of droplets with a sprayer, a foam processing method of foaming the treatment liquid and adhering it in the form of foam, a pad method,
Alternatively, there is a centrifugal processing method disclosed in Japanese Patent Publication No. 59-45788 in which a centrifugal force is applied to bring the napped fibers into contact with a treatment liquid while standing them up, and the method may be selected depending on the necessity. These treatment liquids may be nonaqueous or aqueous emulsions, but aqueous solutions are preferably used from the viewpoint of ease of handling and safety.

Although it is desirable to carry out a heat treatment (curing) in order to firmly adhere the silicon substances A and B to the fiber surface, the present invention is not particularly limited to such treatment (curing).

Normally, if the curing temperature is less than 100°C, long-term processing 1 is required, resulting in a lack of productivity, or the resin film formation is insufficient, which may cause the resin to fall off or cause undesirable problems. . Also, if the temperature exceeds 230°C,
If the raised fabric is damaged, discolored, curled or melted,
Therefore, a suitable curing temperature is preferably 100 to 280°C and 30 to 200°C.

The curing time may vary depending on the curing temperature, catalyst, etc. (although the curing time may vary, as long as it is enough to form a resin film), it is sufficient. If the curing time is 10 seconds or more, a sufficiently strong resin plate will be formed. If the curing time is too long, However, the resin film forming property is not only saturated, but also problems may occur such as poor productivity and energy costs.Therefore, the suitable treatment time is 10 seconds to 80 minutes, preferably 1 to 20 minutes. be.

The napped product of the present invention has a high napped fiber density and shape (although not limited to this). Usually a, ooo to 100,000 hairs/cm2, preferably 5,000 to 80,000 hairs/cm". In the case of a multilayer structure of stinging hair/fluff, the density of standing hairs is usually 50
~5,000 lines/cm2, preferably 100-1,00
0 pieces/cm2, fluff density ζ is usually 1,000 to 5
0.000 lines/cm2, preferably 5.000-80

On the other hand, molecular weight 17 containing 0.7% of TiO2 fine particles,
000 polyethylene terephthalate (hereinafter abbreviated as PET) was melt-spun, stretched 3.5 times, heat treated, and then mechanically wound into a single yarn of 8 inches with a denier of 1.5.
Bias-cut cotton (Sl) was spun to obtain a 60-strand twin yarn. This spun yarn is designated as Y2. This Y2 yarn was used as a ground yarn.

The warp of pile yarn FY1 and ground yarn Y2 are adjusted separately,
Using Y2 yarn for the weft, the pile length is 59 on a double pile loom.

Then, the inner liquid level flowed in to a point 11 rru'n from the base fabric, and the treatment liquid was treated for 7 minutes while keeping the internal temperature constant while heating with infrared rays in a non-contact system from the outside of the outer cylinder. The fluff (Yl) was melted and cut from the base fabric to a length of 11+ nm.Then, the treatment solution was discharged from the system, and a second treatment solution was heated at 98°C containing 0.8% of Chiocation G (Nicca Chemical Industry d).
115% Na0I (aqueous solution was intermittently injected, and the inner liquid level was 213 mm from the base fabric for 20 minutes, at 25 mm
It was treated sequentially for 5 minutes, 24 mm for 1 minute, and 28 dishes for 5 minutes. Then, the treatment solution was drained, and 0.0% acetic acid was added. Neutralize with IN aqueous solution, then wash with water and dehydrate to stop rotation.
The treated pile fabric CP2 was taken out. The treated pile fabric CP2 has a nap length of 11 mm and a nap length of 2.
6 mm, and the tip was tapered and sharpened over a length of B mm.

Next, a polyurethane yarn backing agent serving as a polymeric elastomer was adhered to the back surface of the base fabric in a solid content of 12% to fix the raised nap and the base fabric. This obtained raised fabric is referred to as CF2.

A water-based emulsion (using a nonylphenol emulsifier) of Tsugifune Kokakami treatment agent was diluted and mixed to prepare a water-based emulsion having the composition shown in Table 1, which was used as a treatment liquid.

After immersing the raised fabric CP8 in these treatment solutions,
It was squeezed with a mangle to a squeezing rate of 80%, dried at 80°C, and cured at 160°C for 5 minutes. Next, the cotton was passed through a cotton machine equipped with a needle iro with a needle diameter Q of 32 mm and a needle density of 20 mm to open the fluff 4 times, and then it was shaped using a shaping machine so that the fluff inclination angle was 500. A raised product ZP-Zr2 was obtained.

It was found that the compression recovery rate was higher and the dry cleaning resistance was also better than that of the material to which the material was applied.

Furthermore, it was evaluated using Texture Control II and showed almost no change even after dry cleaning, exhibiting a sliminess that closely resembles that of natural fur, and was excellent in texture.

Example 8 As in Examples 1 and 2, the aqueous emulsions of each yuzu treatment agent were diluted and mixed to prepare an aqueous emulsion having the composition shown in Table 2, and used as a treatment liquid. Napped fabric CP8 was immersed in these treatment solutions and treated in the same manner as in Examples 1 and 2 to produce a napped product ZP5.
~ZP14 was obtained.

As a control product, a napped product ZP1° was obtained by performing the same steps as in Examples 1 and 2 except for the treatment with the treatment solution.

Table 2 shows the results of measuring the friction coefficient, compression recovery rate, and texture of these napped products.

Table 2 As is clear from Table 2, Zr with an adhesion amount of less than 0.1%
2 (outside the invention) had insufficient feel and compression recovery, but those within the scope of the invention had excellent repulsion and feel. Also, the ratio of silicon material A/B outside the present invention is 2/8.
Anything less than that has poor compression recovery properties regardless of the amount of adhesion.
The texture was also undesirable as it had a strong wax-like slimy feel and remained on the hand even after being touched.

In addition, all zP8 napped products are dyed with a mixed dye solution of disperse dye Kayalon Polyester Dark Brown As-200 1.0% (Nippon Kayakushaso), cationic dye Kachilon Brown GO, 5%, and carrier 4800.5 f/II. ℃×5
After dyeing for 0 minutes, the cotton opening process described in Examples 1 and 2,
It was found that the shaped product had repellency and texture comparable to that of Zr8 before dyeing, and was found to be durable.

Example 4 The napped fabric CP of Example 1 was subjected to fluff cutting and pricking thinning treatment using a centrifugal processing machine with varying amounts of processing liquid to obtain napped fabrics CP4 to CP7 having different napped lengths. This napped fabric of CP~ was treated in the same manner as Zr2 according to Example 1 and subjected to finishing processing to obtain napped products ZP16-19. The texture of this napped product was evaluated by touch, and the results are shown in Table 3.

Table 3 As is clear from Table 3, when the nap length is too long as in Zr16, the texture is rough and hard and lacks elasticity, and the effects of the present invention cannot be exhibited. The product had good texture, elasticity, and repellency.
