Structure and Properties Evaluation of Modified Silk/Tencel Blended Yarn
Modified silk is a kind of silk in which sericin is fixed on the surface of silk fibroin.In this pa-per,modified silk/tencel blended yarn was taken as the research object,its morphological structure,hairiness,stem,hydrophilicity and mechanical properties were tested and evaluated,and the properties differences of yarns with different blending ratios and linear densities were compared and analyzed.The results showed that with the increase of the proportion of modified silk,the modified silk was transferred to the surface of the yarn,the ununi-formity of the yarn was 12%～16%,the harmful hair of the yarn was less than 16 pieces/m,the other four kinds of yarns except pure silk yarn were hydrophilic,the yarn strength was 170cN/tex～310cN/tex,the pure silk yarns had the lowest strength,and the yarn had lower bending stiffness.The research could provide reference for the application of modified silk in clothing fabrics.
