Abstract:

A kind of regenerated protein fiber is introduced, and a series of experiments are carried out for the preliminary analysis of its microstructure, morphology, mechanical properties and heat resistance. The results indicate that theregenerated protein fiber has the fiber fineness dispersion of 22.64% and common length specifications of 38 mm and 51 mm; the fiber has a round cross section with micropore in the middle and grooves and fine particles in the longitudinal direction; the fiber has average breaking strength of 3.77cN, breaking elongation of 16.89% and modulus of 15.84cN/dtex ; the fiber has moisture regain of 18.16%, the degree of crystallization of 21.68%, degree of orientation of 71.2% and frictional coefficients of fiber-to-fiber of 0.433; and the temperature should be lower than 110 ℃ in the application process.
