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.展开更多

The structural characterization of prepared blend film was implemented by scanning electron microscopy（SEM） and Fourier transform infrared spectroscopy（FT-IR）, and the optimum ratio was determined by comparing fracture elongation, moisture absorption and moisture retention. The results indicate that the two polysaccharide molecules, sodium alginate and KGM, in the blend membrane have a good compatibility. The surface of blend film is smooth and uniform. The addition of KGM can significantly improve the moisture absorption and moisture retention performance of sodium alginate film, and its mechanical performance is also improved to some extent. The ratio of sodium alginate and KGM is 3.2∶1.5.展开更多
