Dyeing property of kaolin-modified polyester fibers

In order to improve the dyeing property of polyester fibers,kaolin has been used for their modification and some dyeing properties of kaolin-modified polyester fibers were discussed,including the influence of dyeing temperature on the exhaustion,uptake rate of various dyes when rising temperature and built-up property of disperse dyes with different structures.The results indicate that kaolin-improved polyester fibers show good dyeability at low temperature as at 100~110℃,and its dyeing transition temperature is lower than that of ordinary polyester fibers,so at the beginning the dyeing temperature should be mild.The built-up property of disperse dyes with heterocyclic structures are not good on kaolin-improved polyester fibers,which is different from the ordinary polyester fibers.
