| titleOfInvention | Cationic Dyeable Polyester Fiber and Preparing Method Thereof |
| abstract | A type of cationic dyeable polyester fiber and preparing method thereof are disclosed. The preparing method is to manufacture a fiber from a cationic modified polyester through a fully drawn yarn (FDY) process, wherein the cationic modified polyester is composed of terephthalic acid segments, ethylene glycol segments, sodium salt of diethylene ester of 5-sulfoisophthalic acid segments and tert-butyl branched diol segments and a molecular formula of tert-butyl branched diol is as following: n n n n n n n n n n The cationic modified polyester is further dispersed with a high temperature calcined solid heteropolyacid. A final fiber has a dye uptake of 87.8-92.2% and a K/S value of 23.27-25.67 when dyed at 120° C., as well as an intrinsic viscosity drop of 13-17% when stored at 25° C. and R.H. 65% for 60 months. |
