In non-woven fabric, there is a flame retardant non-woven fabric, also known as flame retardant matte non-woven fabric, is a kind of fabric that does not need to be woven, by directional or random placed fibers after friction, holding or bonding, or a combination of these methods and each other made of thin, fiber net or mat. The product has the advantages of high strength, good elasticity, good heat resistance, smooth surface, corrosion resistance and so on. The main principle of flame retardant is to participate in flame retardant. Flame retardant non-woven fabrics can be divided into three categories according to raw materials: polyester flame retardant non-woven fabrics, polypropylene flame retardant non-woven fabrics and viscose flame retardant non-woven fabrics.
Flame retardant non-woven fabric heat resistance is better than polypropylene non-woven fabric, has obvious thermal shrinkage, according to the investigation, the latter when the temperature reaches 140℃ when there is a significant shrinkage, and flame retardant non-woven fabric temperature can reach 230℃ or so, has an obvious advantage.
Anti-aging cycle is also higher than polypropylene non-woven fabric, polyester as raw material, anti-moth, wear resistance, uv resistance, the above characteristics are high polypropylene non-woven fabric. Compared with polypropylene and other non-woven fabrics, it has no water absorption, water intolerance, strong air permeability and other excellent properties.
Flame retardant non-woven fabrics and polypropylene non-woven fabrics in addition to the advantages described above, the two in the selection of raw materials and applications also have this big difference, the production method is also different. But both have their own use characteristics and use areas.
