Abstract

The invention relates to a spinning process technology, in particular to a spinning technology for phosphorus-containing flame-retardant copolyester barium sulfate nano-composite material (NPFRP) fiber. The process comprises the following steps: 1) slicing and drying; 2) melting and extruding; 3) filtering melts ; 4) spinning; 5) cooling and moulding; 6) oiling; 7) winding at a high speed; 8) performing POY bobbin processing; 9) balancing; 10) drawing for increasing elasticity; and 11) inspecting DTY finished products. The temperature for slicing and drying is higher than the crystallization temperature of 8 to 12 DEG C. The spinning temperature is lower than the spinning temperature of 22 to 28 DEG C for ordinary PET fiber. The application experiment of NPFRP slices in the invention indicates that under reasonable condition of spinning process, the spinnability of the slices is good, winding and moulding is good, the DTY processing effect is good, and requirements on garment purpose and home textile can be reached. After the fiber is woven into suspenders, oxygen index can reach 30.5, which satisfies the national flame-retardant standard, that is, LOI is equal to or greater than 28.

Description

technical field [0001] The invention relates to a spinning technology, in particular to a spinning technology of phosphorus-containing flame-retardant copolyester nanocomposite fiber. Background technique [0002] Since the industrialization of polyester (PET) fiber in the early 1950s, it has been favored by people in the spinning industry and consumers for its excellent properties such as high modulus, resilience, light resistance, abrasion resistance, and heat resistance. Welcome, the application field is expanding continuously, and the demand is gradually increasing. In the early 1970s, polyester fiber had already replaced polyamide fiber as the synthetic fiber with the largest output. Polyester fiber is a kind of melting and combustible fiber. If it can be made flame-retardant and made into flame-retardant fiber, then its processed fabrics, especially decorative materials and bedding whose consumption continues to increase, can effectively prevent Fire accidents or red...
