Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pile composition, and more particularly, to a pile composition of synthetic fibers consisting of cutting hair, intermediate hair and cotton wool.
The present invention relates to a pile composition that is suitable for interiors, clothing, toys, and faux fur, in which intermediate hairs and / or cotton hairs are made of acrylic fiber, and from which pile products having excellent bulkiness, waist, and whiteness can be obtained.

[0002]

2. Description of the Related Art A synthetic fiber pile composition most suitable for interiors, clothing, toys, and fake fur consists of cutting hair, intermediate hair, and cotton wool, and has excellent characteristics in terms of texture, appearance, and function. For example, a pile composition for a toy is composed of cutting hairs, intermediate hairs and cotton wool, and the above-mentioned intermediate hairs and cotton wools support the hairs and maintain a napped state. Conventionally, various researches have been conducted on pile products.

[0003] Conventionally, artificial fur using synthetic fibers has been manufactured as a substitute for natural fur, and pile fabric is often used as such artificial fur because its structure resembles fur. For the pile portion of the pile fabric, cutting fibers, intermediate hairs and wool fibers of synthetic fibers are used. For example, Japanese Patent Application Laid-Open No. 2-139476 describes a method of bonding in a brush shape. It is very difficult to bond a plurality of single fibers including an insulated hair fiber with an adhesive and to reproduce the uniform texture. Also, it is difficult to uniformly treat the difference in feel due to the constituent denier and the mixing ratio of the cutting hair fibers with an adhesive, and is extremely inferior to natural fur.

[0004] JP-A-60-209048 discloses a fiber-
A pile composition using shrink fibers having a coefficient of static friction between fibers of 0.230 or less is described. The down hair part uses shrinkable fibers and the guard hair part uses non-shrinkable fibers, but it is a completely different product group.
Significantly inferior waist and whiteness.

[0005] However, the pile composition using the conventional modacrylic synthetic fiber has good physical properties and texture unique to the polymer, but has drawbacks in the characteristics of the pile composition such as bulkiness, waist and whiteness. is there. In particular, pile compositions for interiors and toys have the disadvantage that the bulkiness and waistiness are important and the pile is likely to sleep or fall during use.

[0006]

SUMMARY OF THE INVENTION Accordingly, the present invention has been intensively studied to solve the above-mentioned drawbacks of the pile composition. As a result, when acrylic fibers are used for the intermediate hair and / or the wool, bulkiness, waist feeling, It has finally been found that a pile composition having an excellent whiteness and a product having an excellent texture can be obtained, and the present invention has been completed.

[0007]

That is, the pile composition according to the present invention relates to a pile composition of synthetic fibers consisting of cutting hairs, intermediate hairs and cotton wool, wherein the intermediate hairs and / or cotton hairs are made of acrylic fibers. This is a characteristic feature. According to the second aspect of the present invention, in the configuration of the first aspect of the invention, the fiber cross-sectional shape of the intermediate fiber and / or the cotton fiber is changed to a circular shape, a kidney shape, an elliptical cocoon shape, and a flat shape. And a pile composition.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The pile composition of the present invention is composed of cutting hair, intermediate hair and cotton wool, and the intermediate hair and / or cotton hair is an acrylic fiber.

Examples of the synthetic fibers of the intermediate hairs and / or cotton wool include modacrylic, polyester fibers and vinyl chloride fibers, but they must be acrylic fibers. Intermediate hairs and cotton wool support the cutting hair and maintain the napped state, but modacrylic fiber, vinyl chloride fiber, polyester fiber, etc. have a higher fiber specific gravity than acrylic fiber, so their bulkiness is remarkably inferior, and vinyl chloride fiber modacrylic The fibers are inferior in waist feeling due to lack of whiteness. Polyester fibers have a serious disadvantage in insufficient pile elongation. Therefore, when these fibers are used for the intermediate hair and / or the fluff, the pile will fall or fall during use, and the feeling will deteriorate due to insufficient bulkiness. In particular, pile compositions for interiors and toys are important in bulkiness, waist feeling, and whiteness, and fibers that easily fall or fall during use have a further reduced texture.

In the present invention, among these acrylic fibers, those having a circular, kidney-shaped, elliptical, cocoon-shaped or flat-shaped fiber cross section are preferred. Further, if the whiteness is insufficient, a dyeing process for improving the whiteness is required, and the price of the product is increased, thereby losing the sales competition. The acrylic fiber used in the present invention has a low specific gravity, is inexpensive to dye, which is indispensable for a pile composition, is easy, and has good pile elongation, fastness in dyeing, high bulkiness, whiteness, good waist feeling, and has good intermediate hair and / or cotton hair. When used, pile products can be easily obtained at low cost.

In the present invention, among these acrylic fibers, those having a circular, kidney, elliptical, cocoon-shaped, or flattened fiber cross-sectional shape are preferred. Acrylic fibers having a circular, kidney-shaped, elliptical, cocoon-shaped, or flat-shaped fiber cross section are easy and easy to produce raw cotton, and good in pile processing such as fiber entanglement, card spinning, and sliver knitting. Special fiber cross-sections that are not flat have many restrictions on raw cotton production conditions, are unsuitable for low-cost production, have a large loss in the pile processing step, and have a poor product feel.

In the present invention, among these acrylic fibers, a flat type is more preferable, and the flat type is easily applied to a polisher in one direction, so that the crimp is easily elongated, and the hair has good softness and softness. The animal hair texture of the product is very good.

The above-mentioned pile composition is composed of cutting hairs, intermediate hairs and cotton wool, and has excellent characteristics in texture, appearance and function. For example, a pile composition for a toy is composed of about 30-70% insert hair, about 30-10% intermediate hair, and about 40-20% cotton. If the ratio of the cutting hair is less than 30%, the effect of the cutting hair is small,
If it exceeds 0%, the effect of the intermediate hair and the cotton hair is small. The pile composition having no intermediate hairs and the pile composition having less than 20% or more than 40% cotton are insufficient in bulkiness and waist feeling, and are not suitable for interiors, clothing, toys, fake fur and the like.

As described above, according to the present invention, when acrylic fibers are used for the intermediate hair and / or the wool, a pile composition excellent in bulkiness, waist feeling and whiteness, and a product having an excellent texture can be obtained. Next, the single fiber fineness of the intermediate hair and the cotton wool used in the present invention is in the range of 1.0 to 20 denier, more preferably 2 to 15 denier. If the fineness is thinner than 1.0 denier or thicker than 20 denier, the sliver making property in the carding process is reduced, and the texture is hardly a practical product.

The acrylic fiber used in the present invention is 85
A fiber containing acrylonitrile by weight or more.

The modacrylic fiber used in the present invention is a fiber having less than 85% of acrylonitrile.

The above-mentioned pile composition is a general pile product in which a pile fabric is made with a sliver knitting machine using acrylic fiber and moda acrylic fiber, and a paste is applied to the back surface of the pile fabric and dried. It may be made of a woven or knitted fabric using the obtained yarn. 10% ~ 35% at 130 ℃ x 5 minutes dry heat temperature
A pile composition using about 10 to 40% of shrinkable shrinkable cotton may be used.
