Abstract
Butane-tetra-carboxylic acid (BTCA) and sodium hypophosphite (SHP) were added into cellulose spinning solution. The cross-linked regenerated cellulose fibers were prepared by spinning the solution into a coagulation bath of distilled water and then cured at high temperature. The optimum conditions were obtained according to the single factor experiments. The properties and structure of the fibers were investigated. FTIR and XRD show that the cross-linked fibers were prepared successfully and the crystal form of the fibers remain the same before and after cross-linked. The results indicate that the regenerated cellulose fibers prepared in this study possess more excellent wrinkle recovery ability and wash durability than those treated by finishing process.
