Problems solved by technology

[0003] In view of the above-mentioned related technologies, the inventor believes that after finishing the textile fabric, the strong tearing strength will change significantly, which directly determines the durability of the fabric, so after flame-retardant finishing or modification of polyester fiber or polyester fabric , the tear strength of polyester fabrics will be damaged to varying degrees, resulting in a significant decline in the mechanical properties of flame-retardant polyester fabrics, affecting their service life and scope of application

Abstract

The invention relates to the field of textile materials, and particularly discloses a preparation method of a tear-resistant and flame-retardant polyester fabric. The preparation method of the tear-resistant and flame-retardant polyester fabric comprises the following preparation steps of S1, treating a polyester fabric; S2, filling a modified polyester fabric; S3, preparing a coating modification solution; and S4, preparing a coated polyester fabric. According to the method, the polyester surface is subjected to etching treatment, a large number of dispersed micropores are formed in the surface of the polyester fabric subjected to etching treatment, then a flame-retardant sol solution is loaded to the fiber surface, and after crystallization treatment, the pores and inner walls of the micropores are filled and coated with the coating modification solution, so that the structural performance of polyester fabric fiber is compacted, and the tear-resistant mechanical strength of the polyester fabric is further improved.

Description

technical field [0001] The application relates to the field of textile materials, more specifically, it relates to a preparation method of a tear-resistant flame-retardant polyester fabric. Background technique [0002] Polyester is the most used fiber among synthetic fibers. Polyester has excellent characteristics such as high strength, high modulus, and excellent physical and chemical stability. It has been widely used in outdoor products, architectural decorations, military industry, and automotive interiors, such as jackets, tents, wallpaper, and military rucksacks. However, polyester is a combustible fiber, and its limiting oxygen index (LOI) is about 21%. A single functional textile can no longer meet people's needs. In order to better apply polyester textiles to these fields, polyester textiles must be modified. Make it flame retardant and water repellent. After the polyester fabric is flame-retardant finished at high temperature, the flame-retardant finishing agent...
