Abstract

The invention discloses an antiflaming blended fabric. The antiflaming blended fabric is obtained through padding of a gray fabric in antiflaming treating liquid; the gray fabric is obtained through blending weaving of following raw materials, wherein the raw materials comprise, by weight, 36-40 parts of chinlon fibers, 12-16 parts of polytetrafluoroethylene fibers, 6-8 parts of polybenzimidazole fibers and 3-7 parts of coconut fibers. The antiflaming blended fabric is obtained through padding of the gray fabric in the antiflaming treating liquid and has good antiflaming performance; the antiflaming treating liquid takes 2,4-diamido-6-(3,3,3-tribromo propyl)-1,3,5-triazine and decabromodiphenyl ether which cooperate with each other as an antiflaming agent, the antiflaming performance of the antiflaming treatment liquid is improved, sulfated castor oil improves the permeability, and the performance of attachment of the antiflaming treating liquid to the gray fabric is improved; by adding bisphenol A unsaturated polyester, the attachment force of the antiflaming agent is further improved.

Description

technical field [0001] The invention relates to a fabric, in particular to a flame-retardant blended fabric and a preparation method thereof. Background technique [0002] According to statistics, the number of fire deaths in China reaches thousands of people every year, and fires caused by textiles account for about half, with a direct economic loss of 500 million yuan. Among them, bedding, furniture decoration cloth and clothing are the main causes of fire, especially in building and residential fires, and the proportion of textile fire spread is even greater. Textiles and clothing are in direct contact with human beings. Once they burn, they may cause partial skin burns and suffer pain. In addition, the harmful gases produced by the burning of textiles are also harmful to human life, such as carbon monoxide, carbon dioxide, hydrogen cyanide, nitrogen oxides, ammonia and aldehyde gases, etc., which will cause suffocation or poisoning to death. Existing fabrics are flame r...
