Functional Finishing of Viscose Fiber

The aim of this work is to improve the smoothness of the fiber surfaces and improving the fire resistance and antibacterial effect of viscose fiber with antibacterial, flame retardant and protein finishing agent. The viscose fiber had a higher LOI value after flame retardant treatment than the original fiber samples. This demonstrates that flame resistance is improved by using a flame retardant finishing on viscose fiber. The adequacy of the microstructure was researched utilizing electron magnifying scanning (SEM). The antimicrobial properties of the fibre in the coating plate are superior to the phenomenon of chitosan viscose fibers, and the microstructure of the fibrous film under electrical microscope is considered to have a porous cavity structure of the nanofibrillary membrane obtained by the liquid spun. The large specific surface area and a higher type of curling increases the contact area of chitosan and bacteria and can be bonded or adsorbed into the nano-fiber surface, thereby converting the amino group in chitosan into ammonium root ions. More contact bacteria to inhibit bacterial growth. Protein content of cellulose fibers were measured before dyeing and after dyeing, found that the protein content of the cellulose fibers were increased 4% after dyeing & washing. The SEM images showed that longitudinal surfaces of the chitosan viscose fiber, silkworm chrysalis protein viscose fiber, and protein viscose fiber were smooth more than the common viscose fiber and having grooves of different shades.
