涤纶高收缩ATY的生产技术浅析

ANALYSIS ON THE PRODUCTION TECHNOLOGY OF PET HIGH-SHRINKAGE ATY

介绍了采用ELtex-AT-HS空气变形机,利用物理改性方法生产涤纶高收缩ATY的技术特点,认为用常规纺POY生产高收缩ATY,必须选用较低的变形温度和定型温度及其它适宜的变形工艺以加强对高收缩ATY的沸水收缩率和结构稳定性的控制。

Choosing routin POY as material and using physical modifing method, the production technology of PET high - shrinkage ATY on ELtex-AT-HS air-textured machine is introduced. The result shows that lower temperature of texturing and setting and other proper texturing processes should be choosen to strengthen the control of shrinkage in boiling water and structure stability of high-shrinkage ATY.
