Study on structure and properties of soybean protein/viscose blend fiber
The structure and properties of the soybean protein/viscose blend fiber are analyzed. The crosssection of blend fiber is flat, dumbbell or waistcircle shape, and is core-skin structure. There are many small pores in the cross section. The longitudinal section is not smooth, and there are anomalistic grooves and island shaped cockling on the surface of the blend fiber. The strength and elongation of the fiber is less than that of the viscose fiber, and the mechanics properties are similar to those of the viscose fiber. The volume mass of the fiber is 1.48～1.50g/cm3, which is similar to viscose fiber. The moisture regain is 14.2%, which is just less than that of wool fiber but higher than that of viscose fiber. The logarithm of the mass specific resistance(1gpn) is 7.0, which is similar to that of viscose fiber and less than that of the soybean protein/PVA blend fiber, wool, vinylon, etc. The specific birefringence is 0.009, which is lower than that of viscose fiber and vinylon and similar to that of wool. The glass-transition temperature is 95.218℃ and there is no obvious stick point temperature to this fiber. The decomposition temperature is 306.551℃.The sunlight resistance of this fiber is good.
