Description

[Detailed Description of the Invention] The present invention relates to a new type of coal-like warp knitted fabric with excellent elasticity.

Conventionally, call-top fabrics have been manufactured using a loom, by forming a base fabric, floating pile threads on its surface to form a base fabric, and then cutting the napped threads.

However, this conventional method has the disadvantage of extremely low efficiency and poor productivity, and also lacks versatility as a clothing material since it essentially has no elasticity.

In recent years, in order to improve productivity, it has been proposed to use a warp knitting machine to produce coiled fabrics, but as shown in Japanese Patent Application Laid-open No. 49-14771, the manufacturing principle is different from the conventional manufacturing method using a loom. It is similar to knitting an arbitrary base fabric, and knitting the knitted fabric portion floating on the base fabric,
This knitted fabric portion is cut to create a raised shape.

According to this method, productivity can be improved by using a warp knitting machine, but in order to fix the cutting position of the pipe system, it is necessary that the base fabric does not expand or contract in the weft direction. Therefore, the obtained coal top knitted fabric has significantly reduced elasticity, and does not take full advantage of the benefits of using a warp knitting machine.

This invention was completed as a result of various researches to eliminate the drawbacks of the conventional method. By using a double-layered warp knitted fabric that adopts a special knitting method, it not only improves productivity but also improves the quality of knitted fabric. This is a completely new type of call fabric that takes full advantage of its characteristic elasticity.

The gist of the present invention is a double structure knitted by a warp knitting machine with a double needle bed, and in which the width of the underlap is changed for each course or every few courses to change the length of the connecting yarn. This is a coal-like warp knitted fabric with excellent elasticity, in which the spaced parts of the warp knitted fabric are center-cut, and the cut connecting yarns have a striped pipe shape.

Hereinafter, the present invention will be explained in more detail with reference to the drawings.

FIG. 1 is a sectional view illustrating a double structure warp knitted fabric used in the present invention, and FIG. 2 is a sectional view illustrating a sectional view after center cutting.

In the present invention, as shown in Fig. 1, the base fabrics 1 and 1' are knitted using a warp knitting machine with a double needle bed, and the width of the underlap is changed for each course or every few courses. Connecting yarns 2.2' of different lengths are connected between the base fabrics 1 and 1' by changing the length of the connecting yarns.

By connecting and knitting with 2''... to create a double structure warp knitted fabric, and then center cutting 3 at the interval a, the disconnected yarns form striped raised piles as shown in Figure 2. Two pieces of coal-heavy warp knitted fabric exhibiting forms 4 and 4' are formed.

Here, if the feeding of the connecting yarn to the knitting needles is paused every few courses, a course portion with no raised naps is formed, and a weft-direction coal texture knitted fabric is obtained. if,
A yarn part without napped hair is formed in the wale direction, a coal tone is obtained in the warp direction, and furthermore, in combination with the above-mentioned suspension of yarn feeding, a checkered pattern can be obtained.

Furthermore, the spacing between stripes (the spacing between ridges) can be freely changed by combining pattern links.

In this way, according to the present invention, since the special double structure warp knitted fabric is center-cut, the elasticity of the base fabric is not restricted as in the past, so the warp knitted fabric is Coal textured fabric with excellent elasticity can be obtained by taking advantage of these characteristics.

Also, by changing the amplitude of the underlap, various pipe lengths can be obtained, and by changing the yarn feeding of the connecting yarn, various coil tensions can be obtained.

According to the present invention, the length direction (
Since it is obtained by creating ridges in the warp direction (longitudinal direction) and knitting by changing the width of the underlap for each course or several courses, it is possible to manufacture the ridge pitch within a wide range of sizes. It is.

It is especially effective when creating small pitched ridges.

Currently, a pitch of 1 mm is also possible. However, if the manufacturing method is as disclosed in Japanese Patent Publication No. 47-10626, it is thought that the pitch of the ridges can only be large from the perspective of the knife moving mechanism (device), and it is difficult to obtain a ridge pitch of about 1 mm. seems to be close to impossible.

In other words, it is thought that only the ridge effect of a large pattern can be expressed.

The pitch of the ridges obtained by the present invention can be varied over a wide range of sizes.

In this invention, the materials used for the pile system and base fabric are not restricted in any way, and any of artificial fibers, natural fibers, and mixed fibers thereof can be used, and the shape can be filament yarn or false-twisted yarn. It doesn't matter if it's yarn or spun yarn.

The knitted fabric obtained by the present invention is ideal for clothing, interior decoration, and chair upholstery.

In particular, conventional knitted fabrics for clothing have a problem of not fitting the body shape due to extremely low elongation, but the fabric of the present invention has a good appearance and feel without reducing the functionality of the knitted fabric. It is a knitted fabric.
