cationic dyed polyester
Jun 10, 2022
Cationic yarn belongs to modified polyester, chemical name: polybutylene terephthalate (elastic polyester), abbreviation: PBT, which is also represented by Cd in the factory. Because ordinary polyester (polyethylene terephthalate) has the disadvantages of low moisture absorption, poor dyeing performance, easy accumulation of static electricity, easy fuzzing, etc., it is usually modified with sulfonate as modifier into modified polyester that can be dyed with cationic dyes, or cationic activator is added before spinning or during spinning to prepare modified polyester. Such yarn is called cationic yarn, which does not need to be dyed at high temperature like ordinary polyester, It can be dyed at room temperature.
