Description

DETAILED DESCRIPTION OF THE INVENTION The present invention utilizes two types of fibers with different shrinkage properties - Shawei fibers - to obtain long piloerection, and to make the tips of the long fiber anchors more dramatic, giving a tactile feel. The present invention relates to a method for preparing comfortable artificial fur.

Natural JI at once! IIl is made of thin, dammed fluff for the purpose of heat retention, and thick fluff that is used to visualize the fluff. Various methods have been proposed for producing artificial fur similar to natural fur.

In particular, two or more types of polyester fibers having different solubility in Alka IIK are used, and the tips of the piles are immersed in Alka II water solution to be hydrolyzed, resulting in long and short piles. There is a method of thinning the tip of the pile (No. 48-4110 of the 1980s), and the scissors method produces artificial fur that resembles natural fur K11, but
In terms of texture, flexibility, and appearance, it is not comparable to Tenzetsumo*, and
With this method, it is difficult to immerse the product in alkaline water, making mass production difficult.

On the other hand, it has also been proposed to obtain a suede phase by composing the nape fibers with a complex acid and peeling and dividing the tips or removing the components to form a thin iron complex. (Japanese Unexamined Patent Publication No. 1488-1488). However, when using such a night fiber, a composite fiber made of a polymer of 211 or more is used, which has the disadvantage that the process becomes complicated and the cost increases.

The present inventors used the difference in the port dissolution rate of the solvent or the difference in the hydrolysis rate of the hydrolyzing agent for the positive ester synthetic fiber as a method to overcome the above problems. We have proposed a method for producing artificial fur that is composed of hair-like fibers and short fluff-like fibers and has a standing fluff with a segmented tip.

(Japanese Patent Laid-open No. 5111-31073) However, in this method, the tip of the short fluff loom is dissolved or hydrolyzed, so the tip of the nap is easily worn out and the nap density of the fluff-like nap is insufficient. There was a case.

In addition, in order to treat the R drawing of the raised fabric with a solvent or a hydrolyzing agent and to dissolve or decompose it, it is necessary to increase the purity of the solvent or hydrolyzing agent, and there was an interlayer in the production technology drawing. .

As a result of intensive studies to solve these problems, the authors of this project have developed a combination of a polyester-based synthetic fiber with a special firm shape and a synthetic fiber with greater shrinkage than the polyester-based synthetic fiber. A raised fabric is made and then shrinkage is applied.
a) After that, the tip of the fiber with a special cross-section is divided and
It is thinned and further dyed according to the required #C.
The kite content, flexibility, and appearance are natural fur K11 WLA
The present invention was achieved by discovering that artificial fur can be obtained.

Specifically, the present invention is directed to one or more polyester-based synthetic fibers having a transverse shape with fins, and synthetic fibers with large needles that are smaller in fineness than the polyester-based fibers and have shrinkage properties. A napped fabric containing this as napped fibers is prepared, and then a shrinkage treatment is performed to shrink the highly contractile Shai fibers.Then, a hydrolysis treatment with an alkali is applied to obtain the general polyester synthetic fibers. There is currently a method for manufacturing artificial fur, which is characterized by dividing the tip of the fiber into a plurality of fibers at the constriction of the fur.

The present invention will be explained in detail below.

In the present invention, it is necessary to use synthetic fibers having a cross-sectional shape having one or more constrictions as the napped fibers. Examples of the cross-sectional shapes are shown in Figures A to G in Figure 1. All of them are obtained by spinning with a specially shaped spinneret. The shape of is shown in FIG. 8 M~Ga1C.

The cross-sectional shape shown in the 1st IHC, which has a shape of 5 to 0, is because the raised fibers are elongated in the polyrasher processing process of the raised blanket JllIII manufacturing process, resulting in a raised texture that is more similar to natural fur. ,preferable.

The desirable range of the thickness of the fine raised hair is sdl to 5oda. Additionally, the ribbed woolen fabric must be covered with polyester synthetic fibers. As the positive ester, a polyester having an ethylene terephthalate unit as a main repeating unit is preferable, and among them polyester ethylene terephthalate is preferable for Il#. Copolymerized polyethylene/terephthalate with ethylene glycol etc. is good.

The degree of polyester should be selected appropriately depending on the type of polyester, the shape of the desired fiber, etc., but in the case of polyethylene derephthalate,
Intrinsic viscosity measured with a 0-ri-phenol solution of 'o
! ] is suitable.

On the other hand, as another component, it is necessary to use Shai fiber, which has a smaller fineness and greater shrinkage than the fiber having a cross-sectional shape with a constriction.

Threatening fibers with high shrinkage include: ■Heat-shrinkable fiber ■Shrinkable fibers created by crimped ILK is exemplified.

In the case of (2), the polymers obtained by selecting polyT- or by heating the thermal shoe after IIA include polyester, polyamide, polyamide, polyvinyl chloride, etc. is used.

In particular, polyester is effective, 4IK-806
A polyester having a Me group (M. is a metal element) is preferable from the viewpoint of the Kite Kai 1 color effect.

Polyethylene terephthalate combined with neopentyl glycol is also effective.

0 is conjiegut, false twist, air jet.

Obtained by methods such as scraping.

The higher the degree of shrinkage, the better, but it is better than a fiber with a cross-sectional shape with a constricted part! The preferable range of the fineness of the woven fiber, which preferably has a 0-80% large woven fiber, is 411 to 1.a, and the slenderness % is particularly αS to sd.
l is Arashiko. ■ and ■ are even more effective when used in a subcommittee.

In order to make a raised fabric using the 8 types of threat fibers explained above, there are 1 methods: a method of flocking woven fabrics, non-woven fabrics, etc. with woven fabrics, a method of making pile fabrics, a sliver compacting machine, etc. There are methods to obtain pile fabric such as knitting by knitting with a knife, and using a knife to cut the pile warp system in which the threads of two pieces of woven fabric are raised and lowered on a double loom and connected.

The raised fabric thus obtained needs to be brushed and sheared once, and then subjected to a shrinking process to make it into a highly shrinkable composite fabric. As the treatment method, dry heat treatment, steam treatment, hot water treatment, etc. are applied.

As a result, a raised fabric with two layers, long and short, is obtained.

The raising degree of the raised fabric is game~IS, Ol
)・Book/d, the hair length is 1@-10m. Next, both the napped surfaces are treated with a decomposing agent for the polyester fiber IIAK to decompose the constricted part of the polyester fiber with a 41-lateral Wll-shaped shape, and a plurality of tips of the raised fiber are separated. Divided into books.

Examples of decomposing agents for polyester fibers include IJium hydroxide, potassium hydroxide, and soda carbonate. The usage concentration of these decomposers K Gt
There is no limitation to 41, and the seed koji of Shai Sen which is applicable *i

In this case, if quaternary ammonium salts such as lauryldimethylbenzylammonium chloride and cetyldimethylbenzylammonium chloride are added or used in combination,
This is desirable because it accelerates the hydrolysis of polyester fines.

Raised fabric I! As a method of treating the surface with a decomposing agent, a method of immersing the raised surface in a hydrolyzing agent port liquid may be used, but in this method, (1) the liquid bath scatters during treatment, making it unsafe for fish; Yes, and difficult to handle.

(2) A1 solution after being immersed in a liquid bath for a certain period of time.

In order to discuss disassembly processing, we have no choice but to use batch processing, and the processing efficiency is #! Deteriorate.

(2) It is relatively difficult to control the length and shortness of the seven degrees on the divided side of Toruiku, and the length of Tatetsurin.

(4) Maki-kin, otto to 1ie- carried out on a scale of 1 mulberry
1 length 30~+! It is a technical Km@ to apply a uniform alkali II & luck to a 9m pile fabric while keeping the pile tip immersed in the alkaline water solution for a long time.

There are five points of interest. In order to solve this problem, it is preferable to adopt a method in which the decomposing agent is dissolved in #1 in the viscous binding material and applied as a viscous treatment agent. The viscosity of this viscosity treatment agent is 1. It is necessary to stay within the range of o o o to 15,600 centihoise. Viscosity is 1.
It needs to be within OOO centipoise. If the viscosity is less than 1,000 centipoise, the fluidity of the treatment agent will be too high, causing pilsing! If! The treatment agent that has adhered to IiK flows down to the root of the raised hair, and the treatment liquid evenly covers the edge of the raised hair from the tip to the root, and the entire delicate raised hair is uniformly coated. It is not possible to disassemble it and divide the tip into smaller parts.

Moreover, if it exceeds Is, 01) O centipoise, it becomes difficult to handle and it becomes difficult to apply the treatment agent uniformly to the nap surface. 411#c preferable range is λ00G
~KameOO Centipoise.

To adjust the viscosity of the viscosity agent, wheat starch rice bran, tracanth gum, sodium alginate, -1 cast bean gum,
Methyl cellulose, carboxymethyl cellulose, 7
Cacrystal Gum.

Natural thickeners such as polyvinyl alcohol, polyvinyl acetate, polyacrylic soda, and semi-synthetic thickeners.

An acid-containing thickening agent may be added.

As a method for applying the adhesive layering agent to the nape surface, a knife coating method, a Klavier coating method, a flat screen method, a two-tally screen method, etc. can be used.

Due to the viscosity of the viscous l&layer agent that imparts napped barley, a large amount of the viscous treatment agent adheres to the tip of the napped edge due to its viscosity.
A large amount of one agent and one decomposer adheres 8, and the tip is divided into thin pieces.

Hair standing! The raised fabric with the viscous treatment agent adhered to its surface is left in the device as it is, and the raised edges are dissolved.

It may be decomposed, and if necessary, it may be heated and heated to promote the dissolving action.Heating!
If the process is carried out with 100% or more, the time required for the koji layer can be shortened and the process can be linked, so this is a preferred mode for industrial implementation. As a way to get rid of stomach heat.

The following methods can be mentioned.

(1) Dry heat method: A method of heating in a dry heat atmosphere of 130 to 200'O for 30 seconds to 20 minutes.

(Steaming method: A method of heating in a saturated steam atmosphere of 100-130°0 for 5 to 40 minutes.

(9. Superheated evaporation method: A method of heating in a superheated steam atmosphere of 130 to 200°C for 5 to 30 minutes.

Among them, (2) steaming method is particularly suitable for the present invention. When a viscous treatment agent is used, there is no multiplier effect on the liquid bath, and a fine continuous air layer is created, allowing for the length and width of the nape edge and division of the tip.

Not only does it have the advantage of making it easier to control the degree of thinning, but the hair length after treatment is thicker than when immersed in a solution, and the appearance is similar to that of natural fur. It becomes a state of piloerection similar to .

The raised fabric thus obtained is dyed or printed according to a conventional method. In this case, if polyester fiber with high shrinkage is used, only the general embroidery can be dyed with cationic dye, which is effective in diversifying the colors.

Coating the surface of the long and short nape edges thus obtained with a silicone polymer is an extremely effective means for bringing the texture closer to that of natural fur. In order to form a silicon-1 composite film, (1) a combination of polyepoxide and amino-shixane, (2) a mixture of epoxysiloxane and boria-Z, and a mixture of epoxysiloxane and amino-shixane. Hardware (4) The fibers may be treated with epoxy sheexane and 7-minosilane metal, etc., and the silicone polymer may be hardened on the surface of the fabric. After rinsing, if necessary, the vehicle is processed with urethane ** Go ^ etc. to make artificial fur.

The nappy fabric thus obtained has a long and thick stinging acid component whose tip is divided into fine pieces and has a pointed tip.
It is composed of long and short raised edges IIK consisting of short and thin fluff components made of shrinkable fibers, and is flexible and does not feel stiff when it comes in contact with the skin, and has a texture and appearance similar to that of natural fur E1.
It is similar to M, and can be widely used for the outer lining and for the fur of the ring.

In addition, according to the method of the present invention, compared to the conventional machine, the density of the fluff component is higher, the base fabric is thinner, and the abrasion resistance and fibril resistance are excellent, and the tip of the hair acid content is divided. It is also easy to manufacture and has high 4-hour stability in terms of production technology.
