摘要： Provided is a multifunctional viscose fiber comprising viscose fibers, graphene and nanosilver, wherein the nanosilver is loaded on the graphene in situ. Provided is a method for preparing multifunctional viscose fibers including: a) dispersing graphene in an aqueous solution to obtain a graphene dispersion solution, b) dissolving a silver salt into the graphene dispersion solution, and adding a reducing agent to perform a reduction reaction to obtain a nanosilver-loaded graphene dispersion solution, and c) uniformly mixing the nanosilver-loaded graphene dispersion solution with a viscose solution, and performing spinning to obtain the multifunctional viscose fibers. Experimental results show that as compared to viscose fibers with no nanosilver-loaded graphene added, the multifunctional viscose fibers have a far infrared temperature increase performance increased by not less than 100%, an ultraviolet protecting coefficient increased by not less than 70%, and an antibacterial activity reaching 99.9% and increased by not less than 100%.

摘要： The present invention provides fiber materials, knits and textiles, nonwoven fabrics, miscellaneous daily goods or foam materials having an improved dyeability, bio-compatibility, anti-microbial activity, good bio-degradative property, and being effective for deodorizing uses, growth enhancing uses for plants and medical uses, and having anti-microbial effect produced from the chitin-chitosan viscose which is produced by a xanthogenation reaction of alkaline chitin-chitosan having a different DAC ratio through a pre- and post-immersion steps in an NaOH solution, or from a viscose in which chitin-chitosan and cellulose are solubilized. In the process for producing chitin-chitosan/cellulose fibers, films or foam materials from the chitin-chitosan/cellulose viscose, chitin-chitosan in which DAC ratio and degree of polymerization are adjusted is formed through an improved pre-immersion step in which the chitin material is immersed in a NaOH solution of high concentration at high temperature and through an improved post-immersion step in which the temperature is decreased. The chitin-chitosan/cellulose viscose is produced by a xanthogenation reaction with CS.sub.2 and by dissolving in crushed ice. The viscose obtained or a viscose in which chitin-chitosan and cellulose are solubilized in a desired ratio is used for producing fibers or films, and the viscose in which a foaming agent is added is used for producing foam materials. Span-lace process nonwoven fabrics can be also produced from these viscose.
