Description

The present invention relates to knit knitting with knitting hook with Ohari relates corduroy knitted particularly knit circular knitting machine.

Corduroy knitted fabric is thick and warm, and is suitable for fall and winter outerwear, shoes and hat fabrics, and decorative items such as curtains, curtains, and sofa fabrics. Corduroy is abundant in varieties and is usually divided into ultra-thin, thin, medium, thick and extra-thick depending on the thickness of the chenille yarn. Thick and thin are spaced, local stripes are not checkered stripes, or chenille yarn is cut off to create various varieties with high and low piles . The corduroy structure generally employs medium spun yarn, and the ground structure can be selected from plain weave, twill, warp knitted or the like depending on the characteristics of the variety.

The corduroy manufactured by the conventional loom method has one set of warp and two sets of wefts woven manually or semi-automatically. As shown in FIGS. 1A and 1B, an outline of a conventional loom V-shaped corduroy structure is shown. in schematic cut into V-shaped pile by figures and chenille, a set from the both figures the weft (also called Chiyoko 11, 12) and warp yarns 21 and 22 woven pile that can be knitted durable The fabric and a pair of wefts (also referred to as weft piles 911 and 912) and the warps 21 and 22 are woven together to form regular floating widths 971 and 972, and the floating widths 971 and 972 are cut and V-shaped. It can clearly be seen that they constitute the piles 921, 922 of the mold. When the velvet lengths 911 and 912 are cut to form the V-shaped piles 921 and 922, the knitted surface forms a plurality of vertical velvet lines 2912. Since such as the vertical velvet line of cross-section one by one apparently of 2912 wick (pile), the knitted fabric is said to corduroy.

As shown in FIG. 1A, a plain weave fabric is adopted at 1: 2, and every weft of a single ground 11 weaves two weft piles 911 and 912 in succession, and warps 21 and 22 and the ground 11 and 12 constitute the fabric, and the weft piles 911 and 912 are floated on the fabric with a regular length (generally, the position of 5 or 6 warps), and the weft pile after cutting as shown in FIG. 1B Reference numerals 911 and 912 form V-shaped piles 921 and 922 and are fixed with the fabric (warps 21 and 22 and the lateral sides 11 and 12) interposed therebetween. Fixing method of the V-shaped piles 921 and 922, since the intersection of the V-shaped piles 921 and 922 and the warp yarns 21 and 22 is small, V-shaped piles 921 and 922 is easy to fall off, thus generally transverse to the dense Applies only to very thick calls. Moreover, since these corduroy knitted fabrics are woven by hand or semi-automation, production efficiency is considerably low.

FIG. 2 shows a schematic diagram of a W-shaped pile structure of a conventional corduroy knitted fabric . This figure is also a production by a conventional loom method, adopting a plain weave of 1: 2 and weaving one side of the ground 13 in succession, two weft piles (not shown in the figure) The warp yarns 23, 24, 25, and 26 and the lateral sides 13 and 14 constitute the fabric, and the weft piles 911 and 912 have regular lengths (generally positions of four and five warps) on the fabric. floating weft pi le is W-shaped piles 981 and 982 next after the cutting, but fixed across the fabric (warp 23, 24, 25, 26 and Chiyoko 13,14), such W-shape pile 981, 982 Since there are many intersections between the warp and warp, it is stronger than the V-shaped pile . Generally, it is applied to medium and fine coles, but the W-shaped piles 981 and 982 manufactured by this conventional loom method are also hair. There is a situation that is missing, and the production efficiency depends Of course it is low.

When the above-mentioned conventional corduroy knitted fabrics manufactured by a loom are combined, there is an abrupt improvement in the same problem regardless of whether it is V-shaped or W-shaped.
1. There is a situation in which the pile is easy to fall off and remove hair.
2. The problem of low production efficiency.

Accordingly, a main object of the present invention is to solve the above-mentioned problems, and not only to knit a pile of knitted fabrics firmly, but also to increase the production efficiency of corduroy knitted fabrics .
