Flame-resisting yarn/fabric/clothes

Abstract

The invention provides flame-resisting yarn / fabric / clothes. The flame-resisting yarn / fabric / clothes comprise, by mass proportion, with the sum of mass of three fibers as the standard, the three fibers which are 20-80% of modified polyacrylonitrile, 10-50% of cellulose and 1-50% of polyimide. Vertical burning testing is performed on flame resistance of the flame-resisting yarn / fabric / clothes according to GB / T 5455-2014, and the measured damaged length is smaller than 150 mm, or smaller than 100 mm, or smaller than 50 mm. The damaged length is reduced to a varying degree, and thus different flame resistance requirements are met.

Description

technical field [0001] The invention relates to the fields of chemical industry, textile and labor protection, in particular to a yarn / fabric / garment suitable for providing flame retardancy. Background technique [0002] In the prior art, modified polyacrylonitrile fibers, cellulose fibers, and polyimide fibers have very different physical and chemical properties, and their manufacturers are also very different. It is difficult to fully understand and master their properties for proper mixing and processing. There are modacrylonitrile / lyocell (a type of cellulose fiber) / aramid products on the US market; his company has patents on modacrylic fiber / cotton / aramid, but it doesn't actually quantify the production. Modified polyacrylonitrile produces flame-retardant gas when burning, which can block oxygen, make the mixture flame-retardant as a whole, and generate a certain amount of acid steam at the same time. Because the acid resistance of aramid is not strong, the burning dama...
