文摘

A hydrophilic PET fabric was prepared by a facile aminolysis method about the gradual concentration of ethylenediamine. Dilute ethylenediamine gradually became concentrated enough to aminate the PET fabric during the curing process. The reactive NH2 groups were introduced on PET fibers by dilute ethylenediamine gradually concentrating aminolysis method. The hydrophilicity of aminated PET fabric was improved greatly. The mechanical properties of aminated PET fabric were kept well.
