Description

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 and no ground see-through feeling.

[0002]

2. Description of the Related Art Conventionally, rayon and cotton cut pile fabrics, especially velvet fabrics, are used as high-grade fabrics because they have long hair and uniform hair direction and an elegant silhouette. However, they have the drawbacks of pile cracking (a phenomenon in which the pile collapses and the ground structure can be seen through), and the weight is large and heavy.

In order to improve such a defect, for example, Japanese Patent Laid-Open No. 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. There is disclosed a cut pile fabric in which the raised pile pile is randomized to prevent pile breakage.

However, the woven fabric described in the publication has a nap length of 5 mm or more, and when a napped woven fabric such as so-called chiffon velvet whose nap is less than 5 mm is obtained, the ground structure is seen through. I have a problem.

[0005]

SUMMARY OF THE INVENTION The object of the present invention is to solve the above-mentioned problems of the prior art, prevent the ground fabric from seeping through in a napped woven fabric with a short bristle, and have a natural appearance that has never been seen before. In addition, it is to provide a cut pile fabric having a light and soft surface touch, moderate tension, and waist.

[0006]

Means for Solving the Problems As a result of intensive studies to solve the above problems, the present inventors constructed a ground fabric of a pile woven fabric with a strongly twisted yarn, and randomized the napped pile by utilizing the untwisting torque. It was found that, when it was made to stand, a woven fabric having a short nap length and having no crack through the pile could be obtained.

Thus, according to the present invention, in a cut pile fabric in which the fibers constituting the pile portion have a single fiber fineness of less than 0.5 denier and a pile length of less than 5 mm, the ground structure of the fabric has a single fiber fineness of A cut pile woven fabric is provided which is composed of a strongly twisted yarn of a multifilament yarn having a denier of 1.0 denier or more, and the cut pile naps are randomly arranged.

The present invention will be described in detail below. In the cut pile fabric of the present invention, ultrafine fibers having a single fiber fineness of less than 0.5 denier are used in the pile portion. When the single fiber fineness is more than 0.5 denier, a light and soft texture cannot be obtained. A particularly preferable range of single fiber fineness is 0.
It is 1 to 0.3 denier.

As the polymer forming the ultrafine fibers,
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 dyeing property improving agent, a stabilizer, a plasticizer, a matting agent,
Lubricants, and modifiers and additives such as flame retardants may 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 known methods such as direct spinning method, superdraw method, physical and chemical division such as sea-island type composite fiber or separation-division type composite fiber. Any method can be adopted.

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

That is, if the above fibers are used, it is possible to significantly increase the density of the napped portion after alkali-melting, and it is possible to make the ground see-through of the woven fabric less noticeable.

Further, it is necessary that the ground structure is composed of a strong twist yarn of a multifilament yarn having a single fiber fineness of 1.0 denier or more. When the monofilament fineness is less than 1.0 denier, the obtained fabric has insufficient tension and elasticity.
A particularly preferable single fiber fineness range is 1.0 to 2.0 denier.

The number of twists of the multifilament yarn may be such that the untwisting torque is sufficiently exhibited and the napped piles are 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 is not sufficiently expressed, and it becomes difficult to randomly arrange the napped piles, and the tension and waist of the woven fabric are insufficient. On the other hand, when the number of twists is too large, the texture of the woven fabric becomes coarse and hard. The preferred twist number range is 1500 to 4000 T / m.
Is.

The multifilament yarn may be twisted and set to improve handleability during weaving. However, since it is necessary to develop the untwisting torque in the heating step such as scouring, dyeing or final setting after weaving, it is preferable to carry out the twist setting as low as possible.

The cut pile fabric of the present invention is obtained by using a double loom, connecting two upper and lower ground fabrics with pile warps arranged in the middle, and then cutting the middle pile yarn.

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

In the weaving of the above-mentioned woven fabric, natural fibers such as cotton, regenerated fibers such as rayon, and other synthetic fibers may be woven within a range not impairing the object of the present invention.

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

At this time, when sea-island type composite fibers or peel-off split type composite fibers are used for the pile warp and they are melted or split into ultrafine fibers, the melting and splitting may be carried out 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 melting with caustic soda at the time of relaxation treatment is preferable because no special device is required. .

When relaxing or dyeing,
It is preferable to use a device having a strong rubbing action on the cloth, such as a jet dyeing machine.

In the cut pile fabric thus obtained, the napped pile portions are randomly arranged 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 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 are randomly arranged.

[0027]

As described above, the woven fabric in which the pile pile portions are evenly arranged, particularly the woven fabric having a pile length of less than 5 mm, has the ground texture visible through it.

On the other hand, in the cut pile woven fabric of the present invention, the multifilament yarn constituting the ground structure is a strong twisted yarn, and a large untwisting torque is produced by scouring, dyeing or heating in the final setting step. The tissue dances, and by this action, the napped piles connected to the ground tissue exhibit a random array state.

Therefore, a cut pile woven fabric which does not show through due to cracking of the pile can be obtained despite the short nap length.

Further, since the cut pile fabric of the present invention has ultrafine fibers arranged in the pile portion, it has a light surface touch and is soft, while the ground structure is made of strong twisted yarn, so that the fabric is appropriately stretched and stretched. I also have.

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

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