DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cut pile woven fabric, and more particularly to a cut pile woven fabric having a short nap length but no sense of ground penetration.

[0002]

2. Description of the Related Art Conventionally, rayon or cotton cutpile fabrics, especially velvet fabrics, have long silhouettes, have a uniform hair direction and have an elegant silhouette, and are therefore used as high-quality fabrics. However, it has the drawbacks that pile cracking (a phenomenon in which the pile collapses and the ground structure can be seen through) occurs and the basis weight is large and heavy.

In order to improve such disadvantages, for example, Japanese Patent Application Laid-Open No. Sho 62-191543 discloses that a woven structure is specified by using ultrafine fibers having a single fiber fineness of less than 1 denier, particularly less than 0.5 denier, for a pile yarn. A cut pile woven fabric in which the piles are randomized to prevent pile cracking is disclosed.

[0004] However, the woven fabric described in this publication has a nap length of 5 mm or more, and when trying to obtain a nap fabric such as a so-called chiffon velvet with a nap length of less than 5 mm, the ground tissue is seen through. There is a problem that.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems of the prior art, to prevent the ground tissue from being seen through a nap fabric having a short bristle foot, and to have a natural appearance that has never been seen before. Another object of the present invention is to provide a cut pile fabric having a light and soft surface touch, a moderate tension, and a waist.

[0006]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies to solve the above-mentioned problems, and as a result, the ground structure of the pile fabric is composed of strong twisted yarns, and the unraveling torque is used to randomize the napped pile. It was clarified that a woven fabric without pile ground was obtained even though the nap length was short.

Thus, according to the present invention, in a cut pile woven fabric having a single fiber fineness of less than 0.5 denier and a pile length of less than 5 mm, the ground structure of the woven fabric has a single fiber fineness of less than 0.5 denier. The present invention provides a cut pile woven fabric, which is made of a strong twisted multifilament yarn having a denier of 1.0 denier or more, and in which cut pile nap portions exhibit a random arrangement.

Hereinafter, the present invention will be described in detail. In the cut pile woven fabric of the present invention, ultrafine fibers having a single fiber fineness of less than 0.5 denier are used for the pile portion. When the single fiber fineness exceeds 0.5 denier, a light and soft feeling cannot be obtained. A particularly preferred range of single fiber fineness is 0.1.
It is 1 to 0.3 denier.

The polymer forming the ultrafine fibers includes:
There is no particular limitation as long as it is a polymer capable of forming ultrafine fibers, and examples thereof include polyethylene terephthalate, polybutylene terephthalate, nylon 6 and nylon 66.

In such a polymer, a dye improver, a stabilizer, a plasticizer, a matting agent,
Modifiers and additives such as lubricants and flame retardants can also be included.

As a method for obtaining an ultrafine fiber having a single fiber fineness of less than 0.5 denier, there are known methods such as direct spinning, superdraw, physical and chemical splitting such as sea-island type composite fiber or peelable split type composite fiber. Any method can be adopted.

Particularly preferred is a fiber obtained by splitting a hollow multilayered composite fiber composed of polyester and polyamide with alkali.

That is, the use of the above-mentioned fibers makes it possible to significantly increase the density of the nap portion after the alkali splitting, thereby making it possible to make the woven fabric less visible.

[0014] The ground structure must be composed of a multifilament yarn having a single fiber fineness of 1.0 denier or more. If the monofilament fineness is less than 1.0 denier, the resulting fabric has insufficient tension and waist.
A particularly preferred range of single fiber fineness is 1.0 to 2.0 denier.

[0015] The number of twists of the multifilament yarn may be such that the untwisting torque can be sufficiently exhibited and the piles can be randomly arranged, and may be appropriately adjusted according to the total denier of the multifilament yarn. .

If the number of twists is too small, the untwisting torque will be insufficiently developed, and it will be difficult not only to arrange the piles at random, but also the tension and waist of the fabric will be insufficient. On the other hand, if the number of twists is too large, the texture of the fabric becomes coarse and hard. The preferred range of the twist number is 1500 to 4000 T / m.
It is.

The above-mentioned multifilament yarn may be subjected to a twisting set in order to improve handleability during weaving. However, after weaving, it is necessary that the untwisting torque be developed in a heating step such as scouring, dyeing, or final setting. Therefore, it is preferable that the twist setting be performed at a temperature as low as possible.

The cut pile fabric of the present invention can be obtained by using a double loom, connecting the upper and lower ground structures with a pile warp set in the middle, and then cutting the middle pile yarn.

In this case, the distance between the two ground tissues is adjusted so that the length of the pile is 5 mm or less. If the length of the nap pile exceeds 5 mm, the desired woven fabric as described above cannot be obtained.

In weaving the above-mentioned woven fabric, natural fibers such as cotton, regenerated fibers such as rayon, and other synthetic fibers may be mixed and woven without impairing the object of the present invention.

Next, the above woven fabric is scoured according to a conventional method,
Stained after relaxing.

At this time, when sea-island type composite fibers or peelable split type composite fibers are used for the pile warp and dissolved or split into ultrafine fibers, the dissolution or splitting may be performed simultaneously in the above process. .

For example, when a hollow multi-layer laminated composite fiber composed of polyester and polyamide is used, a method of using a combination of caustic soda and cracking in relaxing treatment is preferable because no special apparatus is required. .

In the relaxation treatment and dyeing,
It is preferable to use a device having a strong kneading action on the cloth, such as a liquid jet dyeing machine.

In the cut pile fabric thus obtained, the pile pile portions exhibit a random arrangement state due to the untwisting torque of the fibers constituting the ground structure.

The cut pile fabric of the present invention may be subjected to various finishing processes. In particular, when the water repellent treatment is performed, a remarkable effect is exhibited in combination with the surface morphology of the woven fabric in which the napped pile portions made of ultrafine fibers exhibit a random arrangement state.

[0027]

As described above, the ground structure of a woven fabric having a uniform pile arrangement, particularly a woven fabric having a pile length of less than 5 mm, can be seen through.

On the other hand, in the cut pile woven fabric of the present invention, the multifilament yarn constituting the ground structure is a strongly twisted yarn, and a large untwisting torque is developed by heating in the scouring, dyeing, or final setting process. The tissue dances, and this action causes the piles connected to the ground tissue to assume a random arrangement.

Therefore, a cut pile woven fabric having no ground penetration due to pile cracking can be obtained despite the short nap length.

Further, the cut pile woven fabric of the present invention has a very fine touch in the pile portion, so that the surface touch is light and soft. Also have.

Further, since the cut pile fabric of the present invention has short naps randomly arranged, a large amount of air is contained in the nap fibers on the woven fabric surface, and is excellent in water repellency and heat retention.

Hereinafter, the present invention will be described more specifically with reference to examples.

[0033]

Example 1 Using a double velvet loom, a double pile fabric having a warp pile structure was woven using the following components, and the pile portion was cut with a knife to obtain a cut pile fabric.

(Warp of ground texture) A double yarn of polyethylene terephthalate of 50 denier / 24 filaments was used. The twist number of the twin yarn is 2000 T / m for the lower twist and 20 for the upper twist.
It was 00 T / m.

(Weft of ground texture) 2000 T / 50 denier / 24 filament polyethylene terephthalate
m, and a multifilament yarn set by twisting at 90 ° C. for 20 minutes was used.

After the above woven fabric is spread and scoured, it is subjected to a liquid jet dyeing machine (Circular RA type, manufactured by Hisaka Seisakusho) for 12 minutes.
Relaxed at 0 ° C. for 30 minutes. At this time, 10g
/ L of caustic soda was added, and the hollow multi-layer laminated multifilament was melted to make the single fiber fineness of the pile portion 0.2 denier.

Next, the above woven fabric was pre-set, dyed and final-set according to a conventional method, immersed in a 5% aqueous solution of Asahigard AG-710 (solid content 18%) manufactured by Meisei Chemical Co., Ltd., and squeezed with a mangle. Drying and heat treatment were performed.

The density of the cut pile fabric obtained is 30
The length of the napped pile was 0 mm / inch, weft 112 / inch, and the length of the pile was 0.8 mm from the ground structure.

The woven fabric has a unique appearance in which raised piles are randomly arranged without the ground structure being transparent due to pile cracking, and has a light and soft surface touch, as well as moderate tension and waist. It was a classy one.

The woven fabric had very good water repellency.

[0042]

[Comparative Example 1] In Example 1, the number of twists of the warp and the weft of the ground structure (in the case of a twin yarn, both the upper and lower twists) was 800 T /
Except having set it as m, it carried out similarly to Example 1.

The obtained woven fabric had little disturbance of the pile, and the ground structure was visible, and the woven fabric had insufficient tension and waist. Further, the water repellency was inferior to that of the woven fabric of Example 1.

[0044]

According to the present invention, a cut pile fabric having a light and soft surface touch, a moderate tension, and a waist can be obtained without the ground structure being transparent due to pile cracking despite the short nap length. It can be suitably used for general clothing such as blousons, windbreakers, coats, pants and skirts, as well as for interior use.
