Fireproof zipper is a kind of zipper that can slow down, terminate or prevent flaming combustion. There are two kinds of zippers: 1. Adding a certain proportion of flame retardant material into polyester pulp; adding flame retardant material into flame retardant zipper has the advantages of low cost and low price. The disadvantages are that the performance (flame retardant index, flame retardant cycle and zipper softness) will decline; 2. Directly use materials with flame retardant effect, such as aramid fiber or carbon fiber and triquartz fiber, and use PPS material ribbon and suture for monofilament. The performance index of self flame retardant materials will be relatively stable, the flame retardant index will be relatively high, and the flame retardant cycle will be equal to the product life cycle. Its disadvantages: high price and cost, yarn strength will be relatively low. 3. The head and teeth of metal zipper can be sealed with flame retardant paint to achieve flame retardant effect; plastic steel glue meter adopts high temperature resistant glue meter.
