摘要
将经质量分数为3％的钛酸酯偶联剂表面修饰过的电气石粉体加入到聚酯(PET)中共混造粒后母粒法纺丝,制备PET负离子纤维。研究了电气石粉体含量对切片热力学性质、纤维结晶性能和力学性能以及负离子性能的影响。结果表明:随着电气石粉体含量的增加,纺丝温度适当降低,纤维结晶度降低,力学性能略有下降,质量分数为2％和4％粉体的纤维的负离子释放分别达到460个／cm3和480个／cm3。
The tourmaline powder was surface modified with 3% titanate by mass fraction and blended with polyester prior to granulating and spinning into negative ion PET fiber via masterbatch method. The effects of tourmaline powder content on the thermomechanical properties of the chips, crystallization behavior and mechanical properties of the fiber and negative ion properties were studied. The results showed that the crystallization behavior of the fiber was decreased and the mechanical properties was also decreased slightly while increasing tourmaline powder content and appropriately decreasing spinning temperature. The releasable negative ion numbers were up to 460 and 480 per cubic centimeter when the mass fractions of the powder were 2% and 4% , respectively.
