Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pile fabric, and more particularly to a method for producing a pile fabric having a loop made of filament yarn.

[0002]

2. Description of the Related Art Generally, a pile fabric is obtained by weaving a weft yarn around a ground warp to weave a pile ground structure, and driving the pile warp yarn into the pile fabric to weave a looper on one or both sides of the pile ground structure. To manufacture pile fabric, a towel loom with a special wefting device is usually used, and the ground warp and the pile warp are formed into separate beams, and the ground warp is woven normally and the pile warp is loosely woven. For weaving, a certain number of wefts are woven at a distance corresponding to the length of one wanna from the weft, and then a large number of wefts are struck strongly and a group of wefts are struck simultaneously to the weft. At this time, the pile warp that has been gently braked is struck forward due to friction with the weft to form a loop.

Conventionally, pile fabrics have generally been woven using cotton spun yarns for pile warps, ground warps and wefts, and it is extremely difficult to weave pile fabrics using filament yarns for pile warps. there were. That is, when a filament yarn is used for the pile warp, sufficient wetting force cannot be obtained between the pile warp and the weft, and the weft that holds down the pile yarn during beating to obtain the kanna is This is because the slip and pile warp cannot be struck forward by a predetermined length, so that a looper having a stable size cannot be formed.

Therefore, in order to generate a large frictional force between the pile warp and the weft, a method of twisting the pile warp or the weft and weaving can be considered. However, sufficient frictional force cannot be obtained by this method. On the contrary, there is a problem that the fabric may be warped or caught.

[0005]

DISCLOSURE OF THE INVENTION The inventors of the present invention have made earnest studies in view of the above problems, and as a result, by twisting a spun yarn into a filament yarn, a sufficient frictional force can be obtained between the pile warp yarn and the weft yarn. The present invention has been completed in view of the above circumstances, and an object of the present invention is to provide a method for stably manufacturing a pile fabric having a looper made of filament yarn.

[0006]

According to the method of the present invention for achieving the above object, a pile fabric comprising ground warp yarns and weft yarns is knitted with pile warp yarns to form a kanna, and a pile fabric is woven. As a warp, a plied yarn obtained by twisting a spun yarn into a filament yarn is used.

As the filament yarn used in the present invention,
For example, polyester fibers, nylon fibers, acrylic fibers, vinylon fibers, aramid fibers, glass fibers, carbon fibers, etc. can be mentioned, but not limited to these. Also, the count of the filament yarn is not particularly limited.

In the present invention, the spun yarn to be twisted with the filament yarn may be, for example, cotton yarn, rayon yarn, hemp yarn, etc., but is not particularly limited thereto. The effect can be obtained even if the number of spun yarns to be twisted and twisted is one, but a plurality of spun yarns are preferable because the effect is large. Further, the yarn count of the spun yarn is preferably thinner than the filament yarn to be twisted.

In the present invention, the number of twists of the plied yarn composed of the filament yarn and the spun yarn is not particularly limited, but is preferably 50 to 1000 turns / m. If the number of twists is small, sufficient frictional force cannot be obtained, and conversely, if the number of twists is too large, partial untwisting of the yarn or twisting of the fabric becomes noticeable, and it tends to be difficult to obtain a uniform fabric. .

The weft yarn used in the present invention is preferably composed only of spun yarn, but may be a spun yarn and a filament yarn which are twisted together. Further, the ground warp yarn in the present invention may be a filament yarn alone, a spun yarn alone, or a ply-twisted yarn obtained by plying both of them.

[0011]

The pile warp of the present invention is composed of a plied yarn obtained by plying at least one spun yarn on a filament yarn.
Since the spun yarns have a strong physical frictional force, a sufficient frictional force can be obtained between the pile warp and the weft. Therefore, when the weft yarn is strongly beaten, the pile warp yarns are struck forward without slipping against the weft yarns, and a clean looper similar to a normal pile fabric is formed.

By applying the method of the present invention, it is possible to obtain a woven fabric having a special function of being stretched to a predetermined length when pulled with a large force. That is, in the method of the present invention, a pile fabric woven using spun yarn having a relatively small tensile strength as the ground warp and using high-strength filament yarn as the pile warp has a force higher than the breaking strength of the ground warp in the warp direction. When pulled, the ground warp breaks and stretches in the warp direction. At that time, Nana made of pile warp gradually dissolves,
Pile fabrics are stretchable until the pile warp yarns are in tension.

【Example】

Example 1 1000 denier aramid fiber (trade name: Kevlar 2)

Comparative Example 1 A pile fabric was woven in the same manner as in Example 1 except that the same aramid fiber as that used in Example 1 was used as the ground warp without twisting. The pile fabric obtained had a pile magnification of at most about 3 times, and the formed looper was also non-uniform.
