摘要：

普通聚酯纤维吸湿性差，易产生静电现象，染色需要在高温高压条件下进行，为改善聚酯纤维的综合服用舒适性，在聚酯中引入聚乙二醇柔性链段、季戊四醇、二氧化钛经共聚制备得到多组分改性共聚酯。对纤维形态结构调控，制备得到截面十字异形仿棉纤维。对仿棉共聚酯纤维的吸湿、抗静电性及染色性进行了测试表征。结果表明共聚酯具有良好的成纤性、力学性能，制备出的短纤维在标准温湿度环境下的回潮率为0.93%，5次洗涤后的比电阻为4.23×108Ω.cm，对气态水分具有快吸速干的特点，可以实现常压沸染。

Abstract:

The application of polyester fiber in the field of clothing is restricted because of its disadvantage such as low moisture absorption, easy accumulation of electrostatic charge, dying under high temperature and pressure. In order to improve the comfort of PET fibers, cotton-like PET fibers were prepared via purified terephthalic acid direct esterification with the incorporation of pentaerythritol at the first esterification stage and polyethylene glycol and titanium dioxide at the second esterification stage. The cross section of cotton-like PET fibers was designated to cross shaped structure during melting spinning process. The moisture absorption process, antistatic property and dyeing behavior were investigated. The results showed that the prepared cotton-like PET fibers had better moisture absorption behavior (0.93% measured at the condition of 20℃，65%)and antistatic property(4.23×108Ω.cm after 5 washes) compared with the unmodified ones. Besides that the cotton-like PET fibers had the characteristic of atmospheric boiling dyeing.

Key words: cotton-like PET, moisture absorption, antistatic property, boiling dying
