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 application relates to the field of textile materials, and specifically 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 includes the following preparation steps: S1, polyester fabric treatment; S2, filling modified polyester fabric; S3, coating modification liquid preparation; S4, coating polyester fabric preparation. In this application, the polyester surface is first etched to form a large number of dispersed micropores on the surface of the etched polyester fabric, and then the flame retardant sol solution is loaded on the surface of the fiber, and after crystallization treatment, it is modified by coating. The liquid fills and coats the pores and inner walls of the micropores, and densifies the structural properties of the polyester fabric fiber, thereby further improving the tear resistance mechanical strength of the polyester fabric.

Description

technical field [0001] The present application relates to the field of textile materials, and more particularly, to a preparation method of a tear-resistant and flame-retardant polyester fabric. Background technique [0002] Polyester is the most used fiber in synthetic fibers. Polyester has excellent characteristics such as high strength, large modulus, excellent physical and chemical stability, etc., and has been widely used in outdoor products, architectural decorations, military industry, automotive interiors and other fields, such as jackets, tents, wallpapers, 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 in these fields, polyester textiles must be modified. Make it flame retardant and water repellent. After the polyester fabric is finished with high temperature flame retardant, the flame retarda...
