Textile fabric and application thereof

Abstract

The invention provides a direct filling type textile fabric and application of the textile fabric, and the textile fabric is good in downproofness and air permeability, is environment-friendly, and reduces the problems of unevenness, wrinkles, filling bars and the like. The textile fabric is woven from a plurality of warps and a plurality of groups of wefts, and is characterized by comprising a surface layer part, a plurality of filling cavities, and long filament yarns and staple fiber yarns in a plurality of warps and various groups of wefts, wherein the surface layer part is provided with a plurality of layers, the layers are respectively a surface layer, at least one middle layer and a lining layer sequentially arranged from outside to inside; the filling cavity is formed in a way that the surface layer and the lining layer are bound with the middle layers alternately, and at least part of the filling cavity is located between the surface layer and the middle layers or between the middle layers and the lining layer, the various groups of wefts respectively correspond to the surface layer, the middle layers and the lining layer one by one, the various groups of wefts are respectively used for weaving wefts of the corresponding surface layer, the lining layer and the middle layers, each warp shuttles from outside to inside and is used for weaving wraps of the surface layer, the lining layer and the middle layers, as well as filament yarn and staple fibre yarn in warps and groups of wefts, and the coverage coefficient of the textile fabric is more than or equal to 1600.

Description

technical field [0001] The invention relates to a fabric and its application, in particular to a direct-filling fabric that is anti-drilling, has good air permeability, is environmentally friendly, and can reduce appearance problems such as unevenness, wrinkles, and crosspieces, and its application. Background technique [0002] Because of its lightness and warmth, down is filled into fabrics to make down products such as home textiles or clothes, which has become a mass consumer product. And because there is a gap between the yarns of the fabric, when the distance of the gap exceeds the diameter of the down, the down will drill out of the fabric from these gaps, so-called downhole phenomenon occurs, which affects the thermal effect, and Affects the appearance, so for down products, anti-drilling down is an important indicator to measure whether its quality is up to standard. At the same time, air permeability is also an important indicator, because when the air permeability...

Problems solved by technology

In the Chinese invention patent of a breathable and fleece-proof fine denier fabric production process (CN102828372B), filaments are combined with a certain process to achieve both breathability and fleece resistance. The process adopted is complicated, difficult to control, and time-consuming laborious and costly

In addition, artificial filaments often have to be treated with reduced fiber opening or benzyl alcohol fiber opening to meet a certain amount of cashmere resistance. However, due to equipment limitations, the fiber opening effect is unstable, so it is easy to cause unstable fabric quality, and artificial filaments The chemical fiber feel of the fabric is heavy, and it is easy to make noise, which affects the wearing comfort

[0006] Moreover, when all filament yarns are used, for direct-filling fabrics, the position of the warp yarns will change between different layers during weaving, which will lead to unstable changes in the displacement of the cloth fell, resulting in large fluctuations in the warp yarn tension , so it will lead to uneven density near the interval between the layers or the surface layer or the inner layer corresponding to the interval, so that crosspieces will appear and affect the appearance of the fabric

[0007] Although the spun yarn made of short fibers has good air permeability, on the one hand, due to the current technical limitations, it is necessary to use organic solvents for coating, lamination, and film treatment to meet the purpose of anti-drilling down, so that the air permeability is low. It is relatively small, and increases the preparation process and cost, and the organic solvents used are easy to volatilize, which will be absorbed by the human body and damage health, and will cause environmental pollution when discharged into the environment, which is not conducive to environmental protection; on the other hand, all of them are made of spun yarn. The obtained fabric has low tear strength and poor durability, and the stability of the fabric's anti-drilling property cannot be guaranteed

[0008] In addition, at present, there are multiple layers of direct-fill fabrics between the surface layer and the inner layer. Since the surface layer warp yarn, the middle layer warp yarn and the inner layer warp yarn are independent weaving systems, the tension of the warp yarn is not easy to control, and the density of the middle layer is higher than that of the outer layer. If the density and the density of the inner layer are too small, the middle yarn will be loose during weaving, which will easily lead to unclear openings and difficult weaving. Moreover, after dyeing, the shrinkage difference between the middle layer and the outer layer and inner layer will easily cause unevenness on the surface of the fabric. Defects such as wrinkles
