摘要
将回收的聚酯织物造粒增黏改性后,经熔融纺丝制得阻燃聚酯纤维,并将其用于针刺阻燃地毯的生产。对织物再生聚酯颗粒的相对分子质量和熔融流动性能进行测试,对常规涤纶短纤、织物再生聚酯短纤的物理性能、大分子结构、结晶度和取向度进行分析,对织物再生聚酯针刺地毯的耐磨性和阻燃性进行研究。结果表明:织物再生聚酯颗粒的相对分子质量较大且分布较宽,其熔体属于典型的假塑性非牛顿流体;织物再生聚酯短纤的细度、断裂伸长率要高于常规涤纶短纤,但其取向度和断裂强度明显较低;织物再生阻燃聚酯短纤生产的针刺地毯耐磨性良好,阻燃性能优良,满足国标规定的B1(B-S1,t1)级要求。
The recycled polyester fabrics which were transformed into particles and modified by increasing the viscosity were made into flame-retardant polyester fibers by melt spinning.The freshly prepared fibers were used to produce needle-punched flame retardant carpets.The molecular weight and melt flow properties of recycled fabric polyester particles were tested.The physical properties,macromolecule structure,crystallinity and degree of orientation of ordinary polyester fibers and recycled fabric polyester fibers were analyzed.The abrasion resistance and flame retardancy of recycled fabric polyester needlepunched carpets were studied.The results show that recycled polyester particles have higher molecular weight and wide distribution.The melt of particles has the characteristics of typical pseudoplastic nonNewtonian fluid.Compared with ordinary polyester fibers,the fineness and breaking elongation of recycled polyester fibers are bigger,but the breaking strength and orientation degree are lower.The needle-punched carpets produced by recycled and anti-flaming polyester fibers have excellent abrasionresistant property and flame-retardant property.The carpets can reach the level of B1(B-S1,t1)stipulated by the national standard.
