The development of aramid flame retardant fabric

We select and use the aramid fabrics, flame retardant viscose fiber, the comprehensive features of the aramid fiber, flame retardant viscose blended (aromatic/viscose 65/35, 50/50), weaving and dyeing finishing technology research, established from raw material to the spinning, weaving, bleaching, and a series of soft finishing production technology, and through one of the key technology research, developed a durable flame retardant properties of aramid fiber series products, has obtained the good effect. Most of domestic flame retardant textiles for pure polyester or cotton finishing products, widespread feel hard, defects such as low strength, meet the fire melt dripping, set the durability, serviceability, and comprehensive performance in one of the most dependent on imports of high-grade durable flame retardant textiles. In order to develop high quality flame retardant products in domestic and alternative imports,

Raw materials and product performance:

1. Raw material performance

Flame retardant viscose is a kind of cellulose fiber containing silicate. With cellulose as the main body, is formed within the macromolecular silicate molecular network and a large number of chemical combined water. Its physical and mechanical properties and is similar to ordinary viscose fiber, not only the wet absorption gas easy dyeing, and acid and alkali resistant bug eat by moth; Compared with other flame retardant fiber, low cost, no pollution, can be processed into a variety of textiles. And through natural biodegradable become mixed soil organic and inorganic. Under the condition of burning carbonization into non-toxic SIO2. Fiber performance indicators such as table 1. Aramid (NOMEX) as part of the aromatic polyamide fiber, for benzol m-phenylene diamine two between fibers. Excellent heat resistant performance; Good flame retardant performance and chemical resistance; Has a good mechanical performance, high fracture strength, elongation, soft, high temperature softening, not melting, carbide, only when burning smoke concentration is low, and low calorific value, washing, after repeated washing flame retardant performance is good, have better dimension stability and serviceability.

2. Product performance

Products with soft handle, good volume resistance, drapability, wet absorption capability and high strength, wear resistance, good smooth finish and color fastness, as well as in case of fire don't melt drip excellent features, such as carbide to satisfy the requirement of the flame retardant fabric clothing, middle and high quality.
