Preparation and properties of PET/CGP blend fiber

Bai Ling (China Textile Academy, Beijing 100025)  
Easy-to-dye polyester(CGP) chip and PET chip were blended at a certain ratio prior to granulating and spinning to produce 150 dtex/36 f PET/CGP blend fiber. The dyeing behavior and mechanical properties of the blend fiber were analyzed. The results showed that the dyeing behavior of PET/CGP blend fiber can be improved considerably at atmospheric boiling dyeing conditions as compared with PET fiber. The dye up-take of the fiber was increased greatly, but the mechanical properties were decreased slightly while raising CGP content. The dye up-take could be 92. 73% and 70. 41% for Disperse Blue 2BLN and Disperse Yellow SE- 4GL, respectively, when the CGP content was 50% by mass fraction.
