A kind of high-density waterproof fabric and its processing method

Abstract

The invention discloses a high-density waterproof shell fabric and a processing method thereof. The high-density waterproof shell fabric comprises a grid layer and a base cloth layer, wherein waterproof coating layers and wear-resistant coating layers are sequentially arranged on the surfaces of the grid layer and the base cloth layer; the base cloth layer is produced from first polyester low stretch yarns and second polyester low stretch yarns in a proportion of 3 to 1 through warp knitting, the monofilament section of each first polyester low stretch yarn is quadrangular star-shaped, the transverse density of the base cloth layer is 25 cycles per centimeter, and the longitudinal density of the base cloth layer is 30 cycles per centimeter; and glass fiber yarns are arranged in warp knitting cycles of the base cloth layer and penetrate through the warp knitting circles and forming holes in an up-down interlacing manner. By utilizing the first polyester low stretch yarn with the quadrangular star-shaped monofilament section, the warp knitting density and mechanical property of the base cloth layer can be effectively improved; and by virtue of the cooperation of the first polyester low stretch yarns, the second polyester low stretch yarns and the glass fiber yarns, the adsorption effect of a coating layer can be improved, and the shell fabric has the advantages of good stabilityand long service life.

Description

technical field [0001] The invention relates to the technical field of textile fabrics, in particular to a high-density waterproof fabric and a processing method thereof. Background technique [0002] With the development of science and technology, people's demand for fabrics is also increasing, and the fabrics used to make canopies, raincoats or tents need to have extremely high waterproof and wear-resistant properties. However, most of the existing fabrics realize the waterproof performance of the fabric by adding a waterproof agent to the common fabric, and the waterproof coating will gradually wear and drop along with the use of the fabric, thereby reducing the waterproof stability of the fabric; and now In order to improve the comfort and breathability of the fabric, some waterproof fabrics often reduce the strength and light resistance of the fabric to a certain extent, resulting in deformation or yarn loss of the fabric due to external pull or long-term sun exposure d...

Problems solved by technology

However, most of the existing fabrics realize the waterproof performance of the fabric by adding a waterproof agent to the common fabric, and the waterproof coating will gradually wear and drop along with the use of the fabric, thereby reducing the waterproof stability of the fabric; and now In order to improve the comfort and breathability of the fabric, some waterproof fabrics often reduce the strength and light resistance of the fabric to a certain extent, resulting in deformation or yarn loss of the fabric due to external pull or long-term sun exposure during use. The phenomenon of weakening of linear performance reduces the service life of fabrics

Therefore, the existing waterproof fabric has the problems of poor stability and short service life.
