What is flame retardant non-woven fabric?
The main component of polyester flame retardant non-woven fabric is polyester, and viscose fiber is a chemical fiber, which is the polymerization product of terephthalic acid or diethyl terephthalate and ethylene glycol. The characteristics are: high strength, good elasticity, good heat resistance, smooth surface, good wear resistance, good light resistance, corrosion resistance and poor dyeability. Its flame retardant mechanism is mainly to add flame retardants. Flame retardant is a material additive, which is generally used in polyester plastics, textiles, etc. When added to polyester, it can achieve the purpose of flame retardant by increasing the ignition point of the material or hindering the flame retardant. burning of materials. The aim is to improve the fire safety of the material.
Type
There are many types of flame retardants, including halogen-based flame retardants, organic phosphorus-based and phosphorus-halogen-based flame retardants, intumescent flame retardants and inorganic flame retardants. At present, brominated flame retardants are the most used halogen flame retardants.
Polypropylene fibers are synthetic fibers made from propylene. Features: high strength, good dry and wet strength, wear resistance, corrosion resistance. Viscose fiber belongs to regenerated cellulose fiber, which has the characteristics of good hygroscopicity, lower breaking strength than cotton, environmental protection, non-toxicity, and higher price than other fibers.
