A study of one-bath alkali-amine hydrolysis and silk-fibroin finishing of polyester microfiber crepe fabric

In this study, the synergistic aminolysis (sodium hydroxide and ethylene diamine in one bath) mechanism of polyethylene terephthalate (PET) microfiber crepe fabric was preliminarily investigated. The results showed that not only active groups (i.e., -NHR, -COOH, and -OH) but also considerable cracks and craters were introduced onto PET fibers, which provided locations for a subsequent crosslinking reaction and mechanical attachment and so facilitated the silk-fibroin finishing.
