Fabric and usage thereof

Abstract

The invention provides straight-filled fabric and usage thereof. The fabric is down-proof, good in air permeability, and environmentally friendly, and can reduce a barre problem. The fabric is formed by weaving of multiple sets of warp yarn and multiple sets of weft yarn, and is characterized by comprising a surface layer, an inner layer and a plurality of filling cavities, wherein the filling cavities are arranged between the surface layer and the inner layer at intervals side by side, the multiple sets of warp yarn and the multiple sets of weft yarn at least comprises filament yarn and staple yarn, and covering coefficients of the surface layer and the inner layer are both greater 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 which is anti-drilling, has good air permeability, is environmentally friendly, and can alleviate the problem of rungs, 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 is not good, one is the water vapor in t...

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
