Abstract: In this article, by carrying out experiments, the ideal dosages of auxiliary agents, modifier and alkali and the proper modification time for cationic modification of cotton fiber were investigated, their influence on the modification effect was analyzed and rational modification process was worked out.Meanwhile, the process for spinning innovative cationic yarn by blending the cationic cotton respectively with polyester, wool and viscose fibers was also introduced.

Key words: cationic cotton; modification; blending
