Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for knitting double-sided pile knitted fabrics, which can be knitted efficiently at high speed using a meridian machine without providing a pin bar, and is a high-grade fabric with a constant and uniform pile tone. It allows items to be organized.

The double-sided pile green area has a velvety appearance, is thick and soft, and has excellent heat retention, so it can be used as a towel,
It is suitable as fabric for nightwear, baby clothes, etc. Conventionally, when knitting a double-sided pile knitting structure using a warp knitting machine, a method has been used in which pin bars are installed before and after the needle row, and therefore members such as levers and cams for operating the pin bars must also be installed. In addition, the knitting mechanism is more complicated than that of a non-pile structure, so it is necessary to knit at a lower rotation speed of the machine, resulting in very poor knitting efficiency and low productivity. Moreover, the pile of the structure is difficult to align, and therefore, it is difficult to knit double-sided pile line fabric suitable for fabrics for towels, nightwear, baby clothes, etc. using a warp knitting machine.

The present invention has been made in view of the above points, and by devising the knitting structure, it is possible to knit a high quality double-sided pile knitted fabric with an ordinary warp knitting machine without using a pin bar, and the pile knitting structure is improved. The method of knitting the double-sided pile knitted fabric of the present invention, which has solved the difficulty, is explained using the example shown in the figure below. Among them, the thread 3 of the chain knitting coin and the thread 2 of the inserted thread coin form a base fabric, and the thread 3 is thrown to every other needle to knit a chain green, and the chain stitch part The three wales W, W, W are connected and knitted with the insertion yarn 2 while changing the insertion direction of each course to form a base fabric.

The back twill yarn 1 crosses the two wales W, W of the base fabric, moves alternately to the left and right, is thrown over every needle other than the base fabric knitting needles, and is underwrapped at the right and left edges, The central part between the wales W and W is knitted in an overlapping manner, and the right hem, left hem, and center part all lack loops, so they are knitted without forming a stitch. The excess thread in the underlapping part of the left handshake will loosen toward the center, and the overlap part in the center will wrap around the needle and then come off, leaving the excess slack thread in the form of a pile. Therefore, the back yarn 1 is caught on both the left and right wales W, W, and is pressed down by the base fabric from the front, and the excess yarn comes out to the back side, forming a pile 1'. On the other hand, the front thread 4 is connected to the chain stitch part of the wale W by overlapping, and in the next course, as shown in Fig. 1, it is transferred across the two wales W, W of the base fabric, and the back thread 1 is thrown The knitting process is repeated by overlapping the passed needle, and then returning to the original chain stitch part of the wale W in the next course, and the thread 4 that crosses the two wales W is held in the chain stitch part. In addition to being organized without being
The overlap part is wound around the needle in the same manner as the back yarn 1, and then removed to form a front pile 4' whose both sides are connected to the chain stitch part. In this way, yarn 1 is underlapping at the left and right bent portions with respect to the needles that are not involved in knitting the base fabric, in other words, it is moved one stitch laterally from the needles that are involved in knitting the base fabric. underlap at the same position.

This has the effect of lengthening the legs of the pile 1' due to the yarns 1 of the back muscle. To explain this with reference to FIG. 1, the back yarn 1 underlaps the NI, which is one of the needles not involved in knitting the base fabric, to form a bent portion la. After needle NI goes down, the needle next to the left N
As a result, the surplus yarn portion lb between the two adjacent needles N1 and N2 is mixed and transferred to the central overlap portion lc of the yarn 1. .

Similarly, in the left bent portion ld, the surplus portion of the thread moves to the central overlap portion lc. In this way, the legs of the pile 1' by the threads 1 are formed long. Also,
As for the back yarn 1, active feeding is finally carried out, but in that case, in order to form a sufficiently large back, it is normal that a larger amount of yarn is supplied than necessary; In many cases, the pile yarn becomes loose between the wales and the pile does not come out completely. However, according to the present invention, by underwrapping the yarn 1 with the needle NI that is not involved in the knitting of the base fabric and is one stitch laterally than the yarn that is involved in the knitting of the base fabric, tension is applied to the yarn 1 and the pile becomes beautiful. It can be sent to Further, in this invention, a pile 1' of the back yarn 1 is formed between each two adjacent wales, and a pile 4' of the front yarn 4 is formed on the wale.

As a result, as clearly shown in Figure 2, piles 1' and 4' are alternately formed with the base fabric in between, and as a result, the resulting knitted fabric has a unique texture. give. In addition, in the case of knitting the front yarn 4 as described above,
The front pile 4' can be formed longer than the back pile 1', but in addition, the front yarn 4 can be knitted by overlapping the adjacent needles without crossing the wale W of the base fabric, as shown in Fig. 3. In this case, the front pile 4' can be formed shorter than the back pile 1'.

Like this. Front piles of various lengths can be knitted by changing the needles through which the front pile yarn 4 is thrown. Next, to specifically explain an example of knitting the double-sided pile knitted fabric of the present invention according to the organization chart shown in FIG. cotton thread with a Nm count of 28/1 for the front thread 4, and a cotton thread with a Nm count of 28/1 for the chain rope thread 3 and the insertion thread 2.

In this case, the front pile should be shorter than the back pile,
Needless to say, it will become a thing. In the above-mentioned embodiment, a three-tempo chain arrangement was shown, but it goes without saying that the same pile striped structure as described above can be knitted even if the slack chain is omitted.

In addition, in the entrusted example, a total of four yarns are used: chain stitch yarn 3 and insertion yarn 2 for forming the base fabric, back yarn 1 for forming the back pile, and front yarn 4 for forming the front pile. Although we have described the case of knitting the double-sided pile knitted fabric of the present invention, for example, it is also possible to use two back yarns and two front yarns to form piles, or to use other inserted yarns (pattern yarns, etc.). ), it goes without saying that it is possible to knit a double-sided pile line fabric similar to the one described above, and in that case, it would be knitted using a meridian machine with five or more stripes.

The knitting method of the double-sided pile knitted fabric of the present invention has the above-described structure, and is knitted using a warp knitting machine with at least four warp threads, and the base fabric is formed with the threads of the chain stitch and the threads of the inserted thread, and the back Since the back pile and the front pile are formed using the yarns of the yarn and the yarn of the front muscle, respectively, there is no need for any special equipment such as a pin bar for pile formation, a lever or a cam for operating the pin bar, and it can be done with ordinary knitting movements. Pile knitting can be performed without reducing the rotational speed of the machine, resulting in a significant improvement in productivity, and it is possible to produce double-sided pile knitted fabrics with no stretch at low cost.

In addition, the pile of the knitted fabric obtained by the knitting method of the present invention is knitted by moving the yarn of the back cloth alternately on the left and right across the two wales of the base fabric and throwing it over needles other than the base fabric knitting needles, The excess thread in between is used as a back pile, while the front thread is connected to the chain stitch part by overlapping, and in the next course, it is wrapped around needles other than the base fabric knitting needles to form the back pile. Since the front pile is formed by repeating knitting that returns to , it is possible to obtain a high-quality double-sided pile knitted fabric with a constant and uniform pile tone. In addition to making it possible to produce fabrics such as nightwear and baby 8 grade fabrics, when knitting the front pile, you can create various lengths by simply changing the needle that wraps the front yarn.

This method has the advantage of being able to form pile knitted piles and easily obtaining pile knitted fabrics suitable for the intended use. Therefore, according to the present invention, it is an epoch-making invention that can efficiently knit at high speed with a warp knitting machine without using any special equipment, and can provide a high-quality double-sided pile knitted fabric at low cost.
