Description

Long pile warp knitted fabric {LONG PILE-WARP KNITTED FABRIC}

The present invention relates to a long pile warp knitted fabric, and more specifically, to a long pile warp knitted fabric which can be formed to be very long in length and that the pile does not fall out.

Typically, the length of the pile is increased by the weft or the hair, and the fabric that has formed hair on the surface of the fabric has been mainly applied as a material for toys. The long pile is pulled and blown in the air by slight pulling or friction. Messy hair and hair on the hands and hands of children playing with these toys are causing children's health, especially respiratory diseases.

In addition, in the case of warp knitted fabric, the file is not pulled out or pulled out, but the length of the file is limited. That is, until now, the pile of the warp knitted fabric has the best length of 5-6 mm, and more than that was impossible in the knitting process. Therefore, it was not enough to achieve various desired effects, so it was not used very much when requesting a very long file.

Therefore, the present inventors have long been engaged in the manufacture of warp knitted fabrics, and if the length of the pile can be extended, the touch can be improved, and the appearance of the knitted fabric can be changed in various ways, thus improving the quality of the product and also for the garment. In addition, the research has been conducted to increase the length of piles in warp knitted fabrics based on the fact that they can be applied to bedding and toys such as blankets and bed sheets.

As a result, the length of the long pile can be changed from a minimum of 7 mm to a maximum of 12 mm using a pile bar, and the unique diameter of the pile standing upright without lying down from the bottom of the total length of the pile. He developed a knitted fabric and filed it with Utility Model Registration No. 99-8357.

Since the product according to the application was shipped on the market, the hairs did not fall out above all, which was sensationally popular in toys, but there was a tendency to expand and contract the width of the fabric. Was exposed.

Therefore, the present inventors have continued to spur further development in order to solve the problems in the above-mentioned filings to improve the technology development, there is no elongation in the width direction as well as in the lengthwise direction as in the above-mentioned fidelity excellent product stability Long pile warp knitted fabric was developed.

That is, by adjusting the speed of the guide bar of the three-bar tricot warp knitting machine and the rotating gear that operates it, the knitting amount of the front bar (L3) can be freely adjusted, which makes the length much longer than the conventional pile. At the same time, the file is not pulled out or pulled out, and because of its excellent form stability, the product manufactured by using it can greatly improve the quality. When used as a material for children's toys such as women's outerwear and toys, hair is pulled out. Since it does not harm the health of the child because it does not get into the clothing or enters the mouth of the child, a very beneficial file is intended to provide a fairly long warp knitted fabric.

The long pile warp knitted fabric according to the present invention is a three-bar tricot warp knitting machine, wherein the back bar is knitted into a tissue of 1-0 / 2-3 and a middle bar of 1-2 / 1-0. It is installed so that the upper end of the guide hole of the front bar descends to the knitting needle ring, and the number of gear teeth of the yarn feeding device of the front bar is changed to adjust the knitting feed amount so that the front bar L3 is 20 stitches or more. It can be jumped and changed freely from 15-16 / 1-0 to 23-24 / 1-0 to form a pile up to at least 10 mm long, and its shape stability is not extended in the width and length direction. It is characterized by excellent.

In addition, this chapter file is crimped and the end of the file can be deformed to create various patterns.

The yarns used in the present invention may be suitably used as yarns made of various fibers such as synthetic fibers, natural fibers or blended fibers thereof, depending on the requirements of the final manufactured article, and the same type of yarns may be used for each bar. Or another kind of yarn may be used, mainly polyester fiber is used.

The long pile warp knitted fabric according to the present invention is all three bars full threaded.

The long pile warp knitted fabric of the present invention is composed of a basic bar by a back bar and a middle bar, and the total length of the pile depends on the floating length of the front bar.

That is, the upper end of the guide hole of the front bar is lowered to the knitting needle ring, and the knitting amount is adjusted to 20 stitches or more, that is, knitting structure 23-24 by adjusting the knitting amount according to the change of the number of teeth of the intermediate gear of the yarn feeder. Up to / 1-0 can also be jumped freely, allowing pile lengths of at least 10 mm.

Hereinafter, the present invention will be described with reference to the accompanying drawings, as illustrated in FIG. 1, the back bar 1 of 1-1 / 2-3 tissue (L1) and the middle bar 1-2 / 1-0 (L2) of the present invention. The basic tissue is organized by the reciprocating operation of the pile, and the pile is cut by the front bar (L3) jumped to the 18-19 / 1-0 tissue and then cut to form a dough formed with the pile. The knitted fabric is then completed by subsequent finishing such as heat treatment, dyeing, raising, cutting, polishing, heat treatment, and the like. Thus, the finished warp knitted fabric forms a pile having a length corresponding to 1/2 of the floating length by the front bar L3.

Therefore, in the case of the warp knitted fabric according to the present invention shown in Figs. 1 and 2 knitted with a tricot warp knitting machine of 28G / G, the length of the pile is approximately 0.9 mm between the knitting and the knitting, so that the front bar L3 is 19-20 / 1-0

Pile length (ℓ) = 0.9 mm × 20 ÷ 2

= 9 mm.

The pile length L can be lengthened up to about 12 mm by changing the structure of the front bar L3 as needed.

In the conventional case, the lowermost position at the time of the lowering of the guide 1 'is as shown in Fig. 4, so that the distance d' between the guide hole 3 'and the knitting needle 2' ring portion 4 'is large. Although it was not possible to walk the knitting yarn at 2 ', in the present invention, by adjusting the number of teeth of the intermediate gear, the upper end of the guide hole 3 as shown in FIG. Can be lowered so that the distance d between the guide hole 3 and the knitting needle 2 and the hook portion 4 is small, so that the knitting yarn can be supplied to the hook portion 4 of the knitting needle 2 in a sufficient amount. The above jumping becomes possible.

In order to more easily understand the features of the present invention, the present invention will be described with reference to the following examples, but the present application is not limited thereto and the scope of utility model registration claims accompanied by those skilled in the art and It is obvious that modifications and variations are possible within the spirit and scope.
