Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textile products, and in particular to a cutting-free jacquard plush fabric and a preparation method thereof. BACKGROUND

[0002] With the development of society and the improvement of people's living standards, people's requirements for home textile products are also getting higher and higher. Plush products are always popular with the public due to their good warmth retention and fluffy hand feeling, low price and other characteristics, and are widely used in the field of blankets. With the development of society and electronic machinery, warp knitting machines have been widely used. People have higher requirements for the appearance of plush products, and no longer satisfy with ordinary appearance. Jacquard plush blankets have emerged as the times require.

[0003] At present, jacquard plush fabrics are used to make jacquard plush blankets. However, due to the weaving structure, the jacquard plush area on the jacquard plush fabric cannot fully cover the base fabric of the jacquard plush fabric, and the two sides of the base fabric of the jacquard plush fabric have extensive exposed areas. Especially in the case of large jacquard patterns, the problem of exposed base fabric on both sides is particularly obvious. In order to maintain the overall beauty of the jacquard plush blanket, the part of the jacquard plush fabric with exposed areas on both sides usually needs to be cut off by cutting. Due to the increase of the cutting production process, a large amount of raw materials are wasted and the production cost is increased. At the same time, the cutting of the jacquard plush fabric will damage the structure of the fabric edge, thereby causing the strength of the fabric edge to decrease and problems such as tearing and cracking to occur, affecting the quality of the jacquard plush fabric. Moreover, due to the damage of the fabric structure during the cutting process, the adhesion of the plush on the fabric edge decreases, causing the fabric to shed. The shed hair is easy to be inhaled into the body, thereby causing harm to the human body. SUMMARY

[0033] Compared with the prior art, the embodiments of the present application have the following advantages:

[0034] 1. The embodiments of the present application effectively fill the exposed areas on the first side and the second side of the base cloth by weaving the filling plush area on the first side and the second side of the base cloth of the jacquard plush fabric, so that when the jacquard plush fabric is used to make a jacquard plush blanket, there is no need to carry out the cutting process, solving the technical problem that in the prior art, because there are exposed areas on the two sides of the base cloth of the jacquard plush fabric, the part of the jacquard plush fabric with exposed areas on the two sides needs to be cut off, resulting in waste of a large amount of raw materials, increase of production cost, decrease of jacquard plush fabric quality and harm to human body.

[0035] 2. The embodiment of the present application solves the problem of the exposed bottom of the jacquard plush fabric by setting the filling plush area on the jacquard plush fabric.

[0080] In some embodiments, in the weaving process of S3, the weaving tension of the yarn on GB4 is consistent with the weaving tension of the yarn on GB3, which is tested by the warp yarn tension meter.

[0081] In summary, the application provides a cutting-free jacquard plush fabric and a preparation method thereof. The first side and the second side of the base fabric of the jacquard plush fabric are knitted with the filling plush area, which effectively fills the several exposed areas on the first side and the second side of the base fabric, so that when the jacquard plush fabric is used to make a jacquard plush blanket, there is no need to cut the edges of the jacquard plush fabric, solving the technical problem that in the prior art, because there are exposed areas on both sides of the base fabric of the jacquard plush fabric, the exposed area on both sides of the jacquard plush fabric needs to be cut off, resulting in waste of a large amount of raw materials, increase in production cost, decrease in quality of the jacquard plush fabric, and harm to the human body. At the same time, by providing the filling plush area on the jacquard plush fabric to solve the problem of exposed areas of the jacquard plush fabric, compared with the cutting in the prior art, not only the structure of the edge of the jacquard plush fabric is not damaged, but also the strength of the edge of the jacquard plush fabric is improved, so that the structure of the entire jacquard plush fabric is more stable, and the gray fabric of the jacquard plush fabric is less likely to have problems such as damage and breakage of the surface of the jacquard plush fabric caused by edge tearing during the subsequent finishing process. At the same time, the product made of the jacquard plush fabric has a longer service life during daily use. By setting the filling plush area to be knitted mainly in the plain weave, and the yarn feeding mode is preferably 1-in-1-out, so that when the filling plush area effectively fills the exposed area, the yarn consumption of the filling plush area is reduced, and the "edge filling points" formed by the plain weave of the filling plush area form a uniform and regular "dot matrix", so that the structure of the filling plush area is more uniform, avoiding the problem that the "edge filling points" on the filling plush area of the jacquard plush fabric are too concentrated, causing the two sides of the jacquard plush fabric to be too thick, thereby affecting the quality and appearance of the subsequent jacquard plush blanket. By using the same group of heads to feed the GB4 for knitting the filling plush area and the GB3 for knitting the jacquard plush area during the warping and weaving processes, and the GB3 and the GB4 always maintain the same horizontal movement rule, so that the normal starting efficiency of the warp knitting machine is not affected, and the production capacity of the jacquard plush fabric is not adversely affected. At the same time, since the GB4 and the GB3 share a group of heads, the technical problem that the yarn required for knitting the filling plush area is insufficient for warping is avoided.
