抗静电涤纶长丝的开发

Development of Antistatic PET Filaments

采用自制抗静电剂PR-86与PET 共混高速纺丝,成功地进行了抗静电涤纶POY、DTY 丝的工业化开发。PET 纤维的晶型和结晶度几乎不变,结晶粒子变小,为纤维力学性能的改善提供了基础。从100%抗静电涤纶的介电性能以及纤维静电衰减历程的考察,进一步证实了前报提出的纤维内部极化、放电的新型抗静电机理。

Using blend spinning of with PET antistatic agent PR-86 prepared by the authors the industrial devclopment of antistatic polyester POY and DTY are carried out successfully.Thecrystal configuration and crystalline grade of PET fibre do not change almost,and the crystalgrain size changes so small that it provids base for improving mechanical property of the fibre.According to dielectric property and static voltage attenuation process of antistatic polyesterfibre,the ncw antistatic mechanism of polarization and discharge within the fibre is verifiedfurther.
