PVC/CPVC发用纤维加工性能及使用性能
Processing performance and using performance of PVC/CPVC wig
摘要
Abstract
Polyvinyl chloride(PVC)/chlorinated polyvinyl chloride(CPVC)fiber using ether extraction of small molecular plasticizers was prepared by melt-spinning technique.The rheological properties,thermal stability and flame retardancy of PVC/CPVC blends with different types and content of heat stabilizers were characterized.The heat shrinkage performances of fibers before and after treated with diethyl ether were analyzed.The results showed that PVC/CPVC blend is pseudoplastic fluid and non-Newtonian index is less than 1. The melt apparent viscosity of PVC/CPVC blends decreased with the increasing of shearing rate and extensional rate. The compatibility of PVC and CPVC is excellent,and the flame retardancy of PVC/CPVC fibers is improved by CPVC.The processing stability of the blends was better when the amounts of Ca/Zn thermal stabilizer and organotin T-580 were 1.2% and 2.4%,respectively.The thermal stability of the fiber was better when the amount of organotin T-580 was 2.4%.After treated by diethyl ether, the thermal shrinkage property of the fiber was reduced,but the performance was improved.关键词
