Preparation,Structure and Performances of Cross-Linked Regenerated Cellulose Fibers

Cross-linked regenerated cellulose fibers(CRCFs) were prepared by wet spinning firstly and then treated by high temperature curing. Cellulose dissolved in ionic liquid together with wrinkle proofing agent and cross-linking agent was employed as spinning solution. The properties and structure of CRCFs were investigated. Fourier transform infrared(FT-IR) spectroscopy and X-ray diffraction(XRD) analysis show that CRCFs were prepared successfully and the crystal form of the fibers remained the same before and after cross-linking. The results indicate that CRCFs prepared in this study possess more excellent wrinkle recovery ability and wash durability than those treated by finishing process.
