Performance detection of duppion silk floss fiber
摘要
Abstract
Main physical and mechanical performances and fiber morphology of doupion silk floss were studied in this paper. Properties of duppion silk floss fiber were compared against the properties of general cocoon silk floss and pupae shirt silk floss in the control group. Besides,the reason for good resilience of duppion silk floss was analyzed. Compressibility, resilience and tensile properties of doupion silk floss were tested. The results showed that the properties of doupion silk floss, including resilience rate 96%, compression rate 53%, average single breaking strength 4.43 cN and breaking elongation 25.42%,were much better than those of control group(general cocoon silk floss and pupae shirt silk floss),and the resilience rate of doupion silk floss met the requirement of national standard of high quality silk floss. Under the electron microscope, fiber diameter of doupion silk floss was thicker and the length was longer. Multiple crossings between the silk fibers were observed under the electron microscopy. The results showed that excellent properties of doupion silk floss were related to its structure.关键词
