Definitions
- the present invention relates to a fabric formed by crocheting yarns through knitting needles and particularly to a corduroy fabric fabricated by a circular knitting machine.
- Corduroy fabrics generally have a greater thickness and a desirable warm-keeping characteristic, thus are suitable for making autumn and winter overcoats, and ornamental articles such as outer layers of shoes and hats, draperies, curtains, surface fabrics of sofas, and the like.
- corduroy fabrics There are many types of corduroy fabrics. Depending on the size of pile strips, they can be divided into extra fine strip, fine strip, medium strip, coarse strip, and broad strip. Other types also are available, such as with coarse strips and fine strips spaced alternatively, without cutting piles on a portion of the strips, or having the piles cut in a bias manner to form alternative heights on the strips, or the like.
- the corduroy fabric is formed by weaving medium yarns.
- the ground fabric can adopt plain weave, twill weave, altered weft plain weave or the like.
- the conventional corduroy fabric is fabricated by shuttle weaving.
- the fabric consists of one set of warp yarns and two sets of weft yarns woven manually or through semi-automatic machines.
- the float wefts 971 and 972 are cut to form V-shaped piles 921 and 922. Then the pile wefts 911 and 912 are cut and the V-shaped piles 921 and 922 direct upwards in V-shape. Hence the fabric surface forms a plurality of longitudinal pile strips 2912 which have a cross section like lamp wicks to become a corduroy fabric.
- the fabric shown in FIG. 1A adopts a 1:2 plain weaving ground.
- the ground fabric is formed by weaving consecutively two pile wefts 911 and 912 for every woven ground weft 11, and the warp yarns 21 and 22, and the ground wefts 11 and 12 are woven to form the ground fabric so that the pile wefts 911 and 912 have a regular length (generally at a length of 5-6 warp yarns) floating on the fabric surface.
- the piles 921 and 922 are formed in a V-shape and fastened by the ground fabric (formed by the warp yarns 21, 22, and weft yarns 11 and 12).
- V-shaped piles 921 and 922 are fastened to the ground fabric at a few cross weaving spots formed by the warp yarns 21 and 22, the V-shaped piles 921 and 922 are easily loosened off.
- a weaving method is generally adoptable to a broad strip corduroy fabric with a high weft density. Ii usually is woven manually or through semi-automatic machines. As a result, production efficiency is lower.
- FIG. 2 for another type of conventional corduroy fabric with a W-shaped pile structure. It also adopts a 1:2 plain weaving ground. It has a ground fabric formed by weaving one weft yarn 13 and two consecutive pile wefts 23 and 24 (no mark in the drawing), and weaving warp yarns 23, 24, 25 and 26 and ground wefts 13 and 14 so that the pile weft has a regular length (generally at a length of 4-5 warp yarns) floating on the fabric surface. After cut, the pile wefts form W-shaped piles 981 and 982 clipped by the ground fabric (formed by the warp yarns 23, 24, 25 and 26, and the ground wefts 13 and 14).
- the W-shaped piles 981 and 982 and the warp yarns are woven with a greater number of crossed spots, thus can form a more secured fastening than the V-shaped piles. It generally is suitable for fabricating medium strip or fine strip corduroy fabrics. But fabricated by the conventional shuttle weaving, the resulting W-shaped piles 981 and 982 still could loosen off, and production efficiency still is not desirable.
- the primary object of the present invention is to solve the aforesaid problems by providing a corduroy fabric that has piles fastened more securely and can be fabricated at a higher production efficiency.
- the corduroy fabric according to the invention is fabricated through a circular knitting machine.
- Its structure includes a plurality of transverse weft yarn sets consisting of at least three yarns.
- Each of the transverse weft yarn sets includes a plurality of pile yarn warp loops consisting of at least two yarns in which at least one yarn in the pile yarn warp loops has at least one pile end, and a plurality of binding yarn warp loops consisting of at least two yarns.
- Each binding yarn warp loop is located at two sides of a selected number of the pile yarn warp loops. At least one common yarn winds around the selected number of pile yarn warp loops to form a binding yarn woven with the pile end in a staggered fashion.
- the pile yarn warp loop and the binding yarn warp loop of the transverse weft yarn set further are woven consecutively with the pile yarn warp loop and the binding yarn warp loop of a longitudinal neighboring transverse weft yarn set to form a plurality of longitudinal warp loop pile zones.

Abstract
Description
- The present invention relates to a fabric formed by crocheting yarns through knitting needles and particularly to a corduroy fabric fabricated by a circular knitting machine.
- Corduroy fabrics generally have a greater thickness and a desirable warm-keeping characteristic, thus are suitable for making autumn and winter overcoats, and ornamental articles such as outer layers of shoes and hats, draperies, curtains, surface fabrics of sofas, and the like. There are many types of corduroy fabrics. Depending on the size of pile strips, they can be divided into extra fine strip, fine strip, medium strip, coarse strip, and broad strip. Other types also are available, such as with coarse strips and fine strips spaced alternatively, without cutting piles on a portion of the strips, or having the piles cut in a bias manner to form alternative heights on the strips, or the like. In general, the corduroy fabric is formed by weaving medium yarns. The ground fabric can adopt plain weave, twill weave, altered weft plain weave or the like.
- The conventional corduroy fabric is fabricated by shuttle weaving. The fabric consists of one set of warp yarns and two sets of weft yarns woven manually or through semi-automatic machines. Referring to
FIGS. 1A and1B for a conventional V-shaped corduroy fabric fabricated by shuttle weaving with the pile yarns cut in a V-shape. It has a ground fabric formed by weaving one set of weft yarns (or calledground wefts 11 and 12) andwarp yarns pile wefts 911 and 912) and thewarp yarns regular float wefts float wefts shaped piles pile wefts shaped piles longitudinal pile strips 2912 which have a cross section like lamp wicks to become a corduroy fabric. - The fabric shown in
FIG. 1A adopts a 1:2 plain weaving ground. The ground fabric is formed by weaving consecutively twopile wefts woven ground weft 11, and thewarp yarns FIG. 1B , after thepile wefts piles warp yarns yarns 11 and 12). As the V-shaped piles warp yarns piles - Refer to
FIG. 2 for another type of conventional corduroy fabric with a W-shaped pile structure. It also adopts a 1:2 plain weaving ground. It has a ground fabric formed by weaving oneweft yarn 13 and twoconsecutive pile wefts 23 and 24 (no mark in the drawing), and weavingwarp yarns ground wefts shaped piles warp yarns shaped piles shaped piles - In short, the conventional corduroy fabrics fabricated by shuttle weaving, either with V-shaped or W-shaped piles, still have common problems remained to be overcome, notably:
- 1. the piles easily loosen off; and
- 2. production efficiency is too low.
- Therefore the primary object of the present invention is to solve the aforesaid problems by providing a corduroy fabric that has piles fastened more securely and can be fabricated at a higher production efficiency.
- To achieve the foregoing object the corduroy fabric according to the invention is fabricated through a circular knitting machine. Its structure includes a plurality of transverse weft yarn sets consisting of at least three yarns. Each of the transverse weft yarn sets includes a plurality of pile yarn warp loops consisting of at least two yarns in which at least one yarn in the pile yarn warp loops has at least one pile end, and a plurality of binding yarn warp loops consisting of at least two yarns. Each binding yarn warp loop is located at two sides of a selected number of the pile yarn warp loops. At least one common yarn winds around the selected number of pile yarn warp loops to form a binding yarn woven with the pile end in a staggered fashion. The pile yarn warp loop and the binding yarn warp loop of the transverse weft yarn set further are woven consecutively with the pile yarn warp loop and the binding yarn warp loop of a longitudinal neighboring transverse weft yarn set to form a plurality of longitudinal warp loop pile zones.
- The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.
