Abstract

The invention relates to a flame-retardant polyamide fabric and a preparation method thereof. The fabric is characterized by being prepared by the following steps of firstly, reacting chloropropyl-POSS with acrylamide to prepare a POSS compound containing double bonds; carrying out a polymerization reaction on the POSS compound containing the double bonds, 2-acrylamide-2-methyl propanesulfonic acid, acrylic acid and sodium methallyl sulfonate to prepare modification liquid; and finally, modifying a polyamide fabric with the modification liquid to obtain the flame-retardant polyamide fabric. The initial limit oxygen index of the flame-retardant polyamide fabric prepared by the method reaches 35% or above, and belongs to the range of a nonflammable material; after 10 times of water washing, the limit oxygen index is not obviously reduced and still reaches 30% or above; and in addition, the flame retardance of the flame-retardant polyamide fabric prepared by the method exceeds that of a purchased flame-retardant polyamide fabric.

Description

technical field [0001] The invention belongs to the technical field of fabric preparation, and in particular relates to a flame-retardant nylon fabric and a preparation method thereof. Background technique [0002] With the continuous development of new textile materials and new technologies, the types of textiles are increasing day by day, and people's demand for functional textiles is also increasing. Flame-retardant textiles, as an umbrella to protect personal and property safety, have attracted more attention from people and achieved rapid development. . [0003] Nylon is a synthetic fiber that can be produced industrially. It has excellent physical properties and textile properties. It is resistant to wear, oil, low temperature, chemicals and deformation. It also has excellent tensile, impact and properties of flexural strength. In addition, nylon fiber is easy to dye, has high strength and good elasticity, so the fabrics made of it are widely used in production and l...
