负氧离子聚酯纤维的研制及性能

研究了一种制备负氧离子聚酯纤维的方法,将聚酯切片结晶、干燥、粉碎后加入经表面改性的负氧离子粉体和分散剂,经过熔融挤出、造粒,制备了负氧离子母粒;用此母粒作为皮层,普通PET作为芯层,通过复合纺丝制备皮芯型复合纤维。通过测试表明:加入4%负氧离子粉体的母粒具有良好的可纺性,采用该母粒制备的皮芯型聚酯复合纤维具有良好的服用性能和释放负氧离子的能力。

Preparation and property of anionic polyester fiber

A preparation method of anionic polyester fiber was researched.Polyester chips were crystallized,dried up,and grinded into powder,and then mixed with dispersant and anionic powder whose surface has been modified.The mixed powder was extruded and chipped,thus obtained the anionic polyester chips which were used as sheath,and ordinary PET as core,sheath-core bi-composite fibers were made.It indicated by testing that the chips containing 4 percent anionic powder have excellent spinnability.This sheath-core bi-composite fiber has good serviceability and capacity of releasing anion.
