Description

Cordoned corduroy

Field of the Invention

The present invention relates to a fabric made by weaving threads, using needles of fabric point and, in particular, to a cordon cordon manufactured by a machine for circular knitted fabrics.

Background of the present invention

The cordoned corduroy fabrics present, of a general mode, superior thickness and a characteristic of heat conservation, desirable, and therefore are suitable for production of coats for autumn and winter, and about ornamental items such as the outer layers of shoes and hats, draperies, curtains, sofa cover fabrics, and the like There are many types of corduroy fabrics. Depending on the size of the hair straps, they can be divided into extra thin strip, thin strip, medium strip, thick strip and wide strip. Be it also has other types, such as with thick strips and thin strips separated alternately, without cutting the hairs in a part of the strips, or that present the hairs cut in a way biased in order to make alternative heights in the strips, or Similar. In general, corduroy corduroy fabric is made by weaving medium threads. The base fabric can adopt a plain fabric, a twill weave, an altered weft plain weave, or Similar.

Conventional cordon corduroy fabric is manufactures using a fabric with shuttle. The fabric is made up of a warp thread set and two weft thread sets tissues manually or through semi-automatic machines. Be refers to figures 1A and 1B for a corduroy cordon fabric Conventional V-shaped made by shuttle fabric with V-shaped hair strands. Includes a fabric of base formed by weaving a set of weft threads (or called base wefts 11 and 12) and warp threads 21 and 22 to fix the hairs, and another set of weft threads (or so-called wefts of hair 911 and 912) and the warp threads 21 and 22 fabrics for make regular floating frames 971 and 972. The frames Floating 971 and 972 are cut to make V-shaped hairs 921 and 922. Next, the hair wefts 911 and 912 are cut and V-shaped hairs 921 and 922 are directed upward in shape of V. Therefore, the surface of the fabric forms a plurality of 2912 longitudinal hair strips that have a section transverse like that of braided wicks of lamps for Become a corduroy cordon fabric.

The fabric shown in Figure 1A adopts a 1: 2 plain weave base. The base fabric is made by weaving consecutively two wefts of hair 911 and 912 for each weft of woven base 11, and warp threads 21 and 22, and wefts of base 11 and 12 are woven to make the base fabric such that hair wefts 911 and 912 have a regular length (generally at a length of 5-6 threads of warp) floating on the surface of the fabric. It makes reference to figure 1B, after having cut the hair wefts 911 and 912, the hairs 921 and 922 are formed in a V-shape and fixed by the base fabric (formed by warp threads 21, 22, and weft threads 11 and 12). Since the hairs fit of V 921 and 922 are fixed to the base fabric at a few points of crossed fabric formed by warp threads 21 and 22, the V-shaped hairs 921 and 922 are easily released. Thus, said tissue procedure can be adopted in a general way for a wide-corded corduroy corduroy with a high density of plot. It is usually woven manually or by machines semi-automatic As a result, the performance of the Production is less.

Reference is made to Figure 2 for another type of conventional cordoned corduroy fabric with a hair structure in the form of W. Said type also adopts a plain tissue base 1: 2 It comprises a base fabric formed by weaving a weft thread 13 and two consecutive 23 and 24 hair wefts (no mark on the drawing), and weaving warp threads 23, 24, 25 and 26 and some base wefts 13 and 14 such that the hair weft present a regular length (usually at a length of 4-5 warp threads) floating on the surface of the cloth After cutting, the hair wefts form hairs in W shape 981 and 982 trimmed by the base fabric (formed by the warp threads 23, 24, 25 and 26, and the base wefts 13 and 14). W-shaped hair 981 and 982 and warp threads are weave with a higher number of cross stitches, and therefore They can make a more secure fixation than V-shaped hairs. In general, it is suitable for manufacturing corduroy fabrics embossed with medium or thin strip. However, manufactured by conventional shuttle fabric, the W-shaped hairs 981 and 982 could still be released, and production performance It is not yet intended.

In short, corduroy fabrics Conventional manufactured by shuttle fabric, either with V-shaped and W-shaped hair, still suffer from some common problems pending resolution, in particular:

one.

the hairs are easily released; Y

2.

he Production yield is too low.

As depicted in the drawings, the set 3 of transverse weft thread comprises three threads 31, 32 and 33, and is ornamented with hooks separately by means of needles a circular knitting machine to make a plurality of hair thread warp loops 4312 and 5312, and a plurality of ligature yarn warp loops 4323 and 5323. In a zone 9 of longitudinal warp loop hair, a loop of hair yarn warp 4312 and another yarn warp loop of hair 5312 comprise two threads 31 and 32. The two threads 31 and 32 of the 4312 hair yarn warp loop are obtained by two hooks of a needle, while the two threads 31 and 32 of the 5312 hair yarn warp loop are obtained by two crochet hooks The thread 31 has a hair end 311. The warp loops of ligature thread 4323 and 5323 they also comprise two threads 32 and 33 respectively arranged in the left side of the hair thread warp loop 4312 and in the right side of another 5312 hair yarn warp loop. two threads 32 and 33 of the ligature thread warp loop 4323 se obtained by means of two hooks of a needle different from that of the warp loops of hair thread 4312 and 5312. And the two threads 32 and 33 of another 5323 ligature thread warp loop are obtained using two hooks of a needle different from those mentioned previously. The warp loops of ligature thread 4323 and 5323 comprise a common thread 33, winding the warp loops of hair thread 4312 and 5312 to make a ligation thread 333 crossed with its own hair end 311.

Another set 6 of transverse weft thread It also comprises three threads 61, 62 and 63 and is decorated with hooks separately by means of a knitting machine needles circular point to make a plurality of loops of hair warp 4612 and 5612, and yarn warp loops Ligation 4623 and 5623. As discussed above, in the same zone 9 of longitudinal warp loop hair mentioned formerly, a 4612 hair yarn warp loop and another 5612 hair yarn warp loop feature two strands 61 and 62. The two threads 61 and 62 of the 4612 hair thread warp loop are obtained by means of two hooks that feed under the set 6 of transverse weft thread through the same needle that forms the knitting yarn warp point 4312 mentioned above, while the two threads 61 and 62 of another warp loop of 5612 hair yarn are obtained using two crochet hooks that feed under the set 6 of transverse weft thread through the same needle that forms another loop of hair thread warp 5312 previously mentioned. The thread 61 also comprises an end of hair 611. The warp loops of ligature thread 4623 and 5623 they also comprise two wires 62 and 63 respectively arranged in the left side of the 4612 hair yarn warp loop and in the right side of another 5612 hair yarn warp loop. two threads 62 and 63 of the warp knitting yarn point 4623 se obtained by means of two hooks that feed under the set 6 of transverse weft thread through the same needle that forms the ligature thread warp loop 4323 mentioned previously. And the two threads 62 and 63 of another warp loop of ligation thread 5623 are obtained using two crochet hooks feed under set 6 of transverse weft thread to through the same needle that forms the thread warp loop of ligature 5323 mentioned above. The warp loops of ligature thread 4623 and 5623 comprise a common thread 63, winding  the warp loops of hair thread 4612 and 5612 to perform a 633 ligature thread crossed with its own 611 hair end.

It should be noted that the two threads 61 and 62 of the 4612 hair yarn warp loop are obtained through the same needle that forms the 4312 hair yarn warp loop, which receives wire that feeds while traveling to an outlet thread of set 6 of transverse weft thread and ornaments with hooks twice, and then the needle releases the threads 31 and 32 of the hair thread warp loop 4312 from a hoop loose thread. Therefore, wires 61 and 62 of the loop of 4612 hair thread warp pass through threads 31 and 32 of the 4312 hair yarn warp loop to perform a style of consecutive cross tissue. And the two wires 61 and 62 of the loop of 5612 hair thread warp are obtained by the same needle that forms the 5312 hair yarn warp loop, which receives thread feed while moving to a thread outlet of the set 6 of transverse weft thread and ornaments with two hooks times, then the needle releases the threads 31 and 32 of the loop of warp of hair thread 5312 from a loose thread ring. Therefore, threads 61 and 62 of the yarn warp loop of 5612 hair pass through threads 31 and 32 of the warp loop of hair thread 5312 to perform a cross weave style consecutive. In this way, the needles move continuously to the next thread exit to feed the threads and ornament hook the threads separately. As a result, it proceeds to make a consecutive cross weave to make a plurality of zones 9 of longitudinal warp hair to obtain the cordon corduroy fabric of the present invention.

Compared to conventional techniques, The present invention provides the following advantages:

one.

He end of the hair warp loop yarn fabric hair corduroy corduroy of the present invention is linked by the thread ligature of the warp loop of ligature thread, therefore the problem of hair loss that occurs with the conventional corduroy corduroy fabric.

2.

The corduroy corduroy fabric of the present invention is manufactured by a circular knitting machine, bringing the speed of production is superior and production yield is higher than with the conventional shuttle fabric.

Reference is made to Figure 4A for a partial schematic view of the knitted fabric structure of a cordon corduroy fabric of the present invention. It is the anterior fabric structure of the cordon corduroy fabric depicted in Figures 3A and 3B after being woven by the circular knitting machine. It should be noted that the zone 9 of longitudinal warp loop hair of each of the sets 3 and 6 of transverse weft yarn has a floating yarn 3111 and 6111. The warp loops of ligature yarn 4323, 5323, 4623 and 5623 they comprise a common thread 63 that coils the hair yarn warp loops 4312 and 4612, and 5312 and 5612 to make the binding threads 333 and 633. Since the crochet knitting needle foot to make the warp loops of hair thread 4312, 5312, 4612 and 5612 and the crochet knitting needle foot to make the warp stitches of ligature thread 4323, 5323, 4623 and 5623 move on different tracks of a cam, therefore , the needle cam of the hair yarn warp loops 4312, 5312, 4612 and 5612 can be designed in a regular cycle on a smooth track without crocheting the threads 33 and 63 to make the binding threads 333 and 633 And the needle cam of the yarn warp loops d The hair 4323, 5323, 4623 and 5623 can be designed in a regular cycle on a smooth track without crocheting the threads 31 and 61 to make the floating threads 3111 and 6111. The binding threads 333 and 633, and the floating threads 3111 and 6111, can be designed so that they cross each other, as shown in Figure 4B. After the floating threads 3111 and 6111 have been cut to make the hair ends 3111 and 611, they are also linked by
ligature threads 333 and 6333, and thus are more firmly fixed and less likely to be released.

Reference is made to Figures 5A and 5B for a partial schematic view of a second type of structure of cordon corduroy fabric of the present invention. Is substantially the same as that represented in figures 3A and 3B. The difference Main is as follows:

In the drawings, the fabric formed by two sets 3 and 6 of transverse weft thread is marked for explanation. The set 3 of transverse weft yarn comprises three threads 31, 32 and 33, and is crocheted separately by the needles of a circular knitting machine to make a plurality of hair yarn warp loops 9312 and a plurality of knitting yarn warp points 4323 and 5323. In a longitudinal warp loop hair zone 91, a 9312 hair yarn warp loop comprises two threads 31 and 32 formed by two hooks of a needle. A thread 31 has two hair ends 311. The warp loops of ligature thread 4323 and 5323 also comprise two threads 32 and 33 respectively arranged on the left and right sides of the hair thread warp loop 9312. The two threads 32 and 33 of the ligature yarn warp loop 4323 are obtained by two hooks of a different needle than the hair yarn warp loop 9312. The two yarns 32 and 33 of the ligature yarn warp point 5323 are obtained by two hooks of a needle different from those mentioned above. The warp loops of ligature thread 4323 and 5323 comprise a common thread 33, winding the loop
of warp of hair thread 9312 to make a ligation thread 333 crossed with the two ends of hair 311.

Another set 6 of transverse weft thread It also comprises three threads 61, 62 and 63, and is decorated with hooks separately by means of a knitting machine needles circular point to make a plurality of loops of 9612 hair yarn warp, and yarn warp loops ligature 4623 and 5623. Like those mentioned above, in a zone 91 of longitudinal warp loop hair, a loop of warp of hair thread 9612 comprises two threads 61 and 62. The two strands 61 and 62 of the hair yarn warp loop 9612 se obtained through two hooks that feed below the set 6 of transverse weft thread through the same needle that forms the 9312 hair yarn warp loop mentioned above. A thread 61 has two ends of hair 611. The loops of warp of ligature thread 4623 and 5623 also comprise two wires 62 and 63 respectively arranged on the left sides and right loop of hair warp loop 9612. The two threads 62 and 63 of the knitting yarn warp point 4623 are obtained by means of two hooks that feed below set 6 of transverse weft thread through the same point needle ligature thread warp 4323 mentioned above. Both yarns 62 and 63 of the warp knitting yarn point 5623 se obtained through two hooks that feed below the set 6 of transverse weft thread through the same loop needle of warp of ligature thread 5323 mentioned above. The two warp loops of ligature thread 4623 and 5623 comprise a common thread 63, winding the hair yarn warp loop 9612 to make a 633 ligature thread crossed with the two ends of hair 611.

It should be noted that the two threads 61 and 62 of the 9612 hair yarn warp loop are obtained by the same needle that forms the 9312 hair yarn warp loop, which receives thread by feeding a thread outlet of thread assembly 6 of transverse weft and ornaments with hooks twice, to then the needle releases the threads 31 and 32 from the point of 9312 hair yarn warp from a thread loose ring. For the  both threads 61 and 62 of the warp knitting yarn 9612 pass through threads 31 and 32 of the yarn warp loop 9312 hair for a consecutive cross weave style. In this way, the needles move continuously to the next thread outlet to feed the threads and ornament with hooks the threads. As a result, a cross weave is made consecutive to perform a plurality of areas 91 of hair from longitudinal warp to make the cordon corduroy fabric of the present invention

Reference is made to Figure 6 for a view. partial schematic of a third type of corduroy fabric structure of the present invention. Zone 9 Loop Hair Longitudinal warp is the same as shown in the figure 3B. Alterations can be seen in Figure 6.
