Description

Golden Denim Fabric {Corduroy Fabric}

The present invention relates to a fabric formed by crocheting yarns through knitting needles (knitting needles), and in particular, manufactured by circular knitting machines (hereinafter referred to as circular knitting machines). Relates to a goldenden fabric.

Corduroy fabrics are thick and have certain heat retention properties, making them suitable for the manufacture of upholstery in autumn and winter overcoats, outer layers of shoes and hats, pleats, curtains, and surface fabrics of sofas. The goldenden fabric has many forms. Depending on the size of dividing the pile, it can be divided into extra fine strips, fine strips, intermediate strips, coarse strips, and broad strips. Other forms are possible, such as having coarse strips, optionally containing fine strips, having no piles cut at portions of the strips, or having piles cut by the bias method for the selective height formation of the strips. . Generally, goldenden fabrics are made by weaving medium size yarns. The ground fabric may be selected from plain weave, twill weave, modified weave plain fabric, and the like. Conventional goldenden fabrics were made by shuttle weaving. The fabric was either manually woven using a pair of warp and two pairs of wefts or made through a semi-automatic machine. 1A and 1B, there is disclosed a conventional V-shaped goldenden fabric made by shuttle weaving with a P-shaped cut yarn. Raw fabrics are produced by weaving and weaving one set of wefts (or original wefts 11 and 12) and warp yarns 21 and 22 on piles, or another set of wefts (or pile wefts 911 and 912) and warp yarns. (21, 22) were produced by a method of weaving to form a weft yarn (971, 972) that is constantly floating. The floating wefts 971 and 972 are cut into V-shaped piles 921 and 922. The pile wefts 911 and 912 are then cut and the V-shaped piles 921 and 922 are sent over the V-shaped. Thus, the fabric surface is formed with a plurality of longitudinal pile strips 2912, which have a cut surface like a ramp wick to form a goldenden fabric.

The fabric shown in FIG. 1A then employs a 1: 2 plain weave ground. The ground fabrics are formed by weaving two pile wefts 911 and 912 in succession per ground weft 11, and the warp yarns 21 and 22 and the ground wefts 11 and 12 are woven to form the ground fabric. The pile wefts 911 and 912 will have a constant length (generally between 5 and 6 warp lengths) to float along the fabric surface. According to FIG. 1B, after the pile wefts 911, 912 are cut, the piles 921, 922 are formed in a V-shape, and the ground fabrics (warp 21, 22 and weft 11, 12) Formed). Since the V-shaped piles 921, 922 are tied to the ground fabric in some orthogonal weave spots formed by the wefts 21, 22, the V-shaped piles 921, 922 are easily attached. It is released. Thus, this weaving method is commonly used for golden strip fabrics of broad strips with high fabric density. It is usually woven manually or by a semi-automatic machine. Thus, the production efficiency is further lowered.

Figure 2 shows another form of a conventional goldenden fabric having a W-shaped pile structure. This also uses a 1: 2 plain weave ground. Furthermore, one warp 13 and two successive pile warps 23 and 24 are woven, and the warp yarns 23, 24, 25 and 26 are woven with ground wefts 13 and 14 so that the pile fabric It has a constant size (typically about 4-5 wefts) suspended on the fabric surface. After being cut, the pile fabric is fixed by the ground fabric (formed by warp 23, 24, 25, 26 and ground weft 13, 14) to form W-shaped piles 981, 982. do. W-shaped piles 981 and 982 and warp yarns are woven to have a large number of orthogonal spots, which are more tightly bound than V-shaped piles. Therefore, it is suitable for the production of medium strip or fine strip goldenden fabric. However, the W-shaped piles 981 and 982 manufactured according to the conventional shuttle weaving still have a problem that can be solved, and thus the production efficiency cannot be obtained to a desired level.

In summary, conventional goldenden fabrics of W-shaped or V-shaped fabricated according to the shuttle weaving method have the following problems left unsolved:

1. Files can be easily unpacked;

2. The production efficiency is too low.

Therefore, the main object of the present invention is to solve the problems of the conventional goldenden fabric as described above, to provide a method that can secure the file more securely, and can be manufactured with high production efficiency.

In order to achieve the object of the goldenden fabric according to the present invention as described above, the present invention is prepared using a circular knitting machine. The structure of the goldenden fabric according to the invention comprises a plurality of transverse wefts consisting of at least three yarns. Each transverse weft consists of a plurality of yarn yarn warp loops and at least two yarns consisting of at least two yarns of at least one yarn in pile yarn warp loops having at least one pile end Binding yarn warp loops.

At least one conventional yarn is wound around a selected number of pile yarn warp loops to produce binding yarns woven to have pile ends in a staggered manner. Binding yarn warp loops of orthogonal wefts set with pile yarn warp loops further comprise binding yarn warp loops and pile yarn warp loops of longitudinal and neighboring transverse weft yarns to form a plurality of longitudinal warp loop pile regions. Then weave.

Further objects and advantages of the invention will become more apparent with reference to the following detailed description of the invention and the accompanying drawings, which are described in detail below.

Goldenden fabrics made according to the present invention can securely secure piles and can be produced with high production efficiency.

In addition, the two yarns 32 and 33 of the other binding yarn warp loops 5323 are obtained by two kinds of crocheting with one needle different from the one described above. The pile yarn warp loops 4312 and 5312 are wound to form binding yarns 333 orthogonal to their own pile ends 311, while the pile yarn warp loops 4312 and 5312 are common yarns 33. Will have

The other transverse weft set 6 includes three yarns 61, 62, 63, forming a plurality of pile yarn warp loops 4612, 5612 and a plurality of binding yarn warp loops 4462, 5623. In order to do this, the needles of the circular knitting machines are each crocheted. As described above, the longitudinal warp loop pile region 9 is described above, with one pile yarn warp loop 4612 and the other pile yarn warp loop 5612 being two yarns 61, 62). The two yarns 61, 62 of the pile yarn warp loop 4612 are fed under the set of transverse weft yarns 6 using the same needle to form the pile yarn warp stitch 4312 as described above. Obtained by two kinds of crocheting, the two yarns 61, 62 of the other pile yarn warp loops 5612 use the same needle to form the other pile yarn warp loops 5312 as described above.

The pile yarn warp loops 4603 and 5623 are wound to form binding yarns 633 orthogonal to their own pile ends 611, while the pile yarn warp loops 4612 and 5612 are common yarn 63. Will have

Since the two yarns 61 and 62 of the pile yarn warp loops 4612 are obtained from the same needle forming the pile yarn warp loops 4312, a set of transverse weft yarn sets 6 are supplied with the yarns. After moving to the yarn exit to perform two crochet needles, the needle is released from the yarns 31, 32 of the pile yarn warp loop 4312 from the yarn escape ring. Accordingly, the yarns 61 and 62 of the pile yarn warp loops 4612 pass through the yarns 31 and 32 of the pile yarn warp loops 4312 to form a continuously orthogonal woven form. The yarns 61 and 62 of the pile yarn warp loops 4612 are obtained by the same needle that forms the pile yarn warp loops 5312, so that the yarns of the transverse weft yarn set 6 are fed After moving to the yarn exit to perform two crochet needles, the needle is released from the yarns 31, 32 of the pile yarn warp loop 5312 from the yarn escape ring. Accordingly, the yarns 61 and 62 of the pile yarn warp loops 5612 pass through the yarns 31 and 32 of the pile yarn warp loops 5312 to form a continuous orthogonal woven form. Thus, the needles are continuously moved toward the next yarn exit to feed the yarn or to each of the crochet yarns. As a result, continuous orthogonal weaving proceeds to form a plurality of longitudinal fabric pile regions 9, forming a goldenden fabric according to the invention.

This invention has the following advantages over the prior art:

1. Since the pile ends of the pile yarn warp loops of the golden yarn fabric of the present invention are tied by the binding yarns of the binding yarn warp loops, there is no problem of unwinding the piles generated in the conventional goldenden fabric.

2. Since the goldenden fabric of the present invention is manufactured by using a circular knitting machine, the production speed is high and the production efficiency is higher than that of the conventional shuttle weaving method.
