The results show that the speed of dyeing and the percentages of balance dyeing have a sharp increase after being treated. So the dyeing temperature and the dosage of acid can be reduced without damaging the bulk fiber structure.展开更多

Results of grafting experiments show that the grafting ratio on the surface of the fibers is low when the grafting polymer chain is not cross linked. Under scanning electron microscope (SEM), it is discovered that there is no different morphology between the raw fibers and their being coated with soybean lecithin. The composites exhibit a good stability of soybean lecithin layer, and better anti coagulant property than the sulfonated grafting fibers or raw fibers.展开更多

A nonlinear viscoelastic model has been proposed to describe the tensile behavior of soybean protein yarns. The model is composed of a Maxwell element, a linear spring and a nonlinear spring. The tensile properties of soybean protein yam are analyzed. The stress-strain curves of the yams are fitted. The average breaking tenacity and specific work of rupture are calculated using the average breaking strain. Comparisons indicate that theoretical predictions conform the experimental results very well.展开更多

文摘The soybean fiber was treated with low temperature plasma and the dyeing performance of the treated soybean fiber was also researched. The results show that the speed of dyeing and the percentages of balance dyeing have a sharp increase after being treated. So the dyeing temperature and the dosage of acid can be reduced without damaging the bulk fiber structure.
