粘胶基和维纶基大豆蛋白纤维理化性能对比研究

Soybean protein/viscose fiber and soybean protein/PVA fiber are both protein fibers. However, the physical and chemical properties of soybean protein/viscose fiber are different from those of soybean protein/PVA fiber due to the difference of their matrix. Soybean protein/PVA fiber has been on the market for a long time and its properties are well known, while the performances of soybean protein/viscose fiber are rarely been know for it’s a new kind of textile fiber recently exploited by Weifang Helon Co., Ltd. The structure and properties of both fibers were investigated for comparison. The results showed that the longitudinal shape of soybean protein/PVA fiber is similar to that of soybean protein/viscose fiber, while the section shape differs a lot. Both soybean protein/viscose fiber and soybean protein/PVA fiber has fine tensile and absorption properties, good friction properties and chemical stability, excellent heat-resistant and lightfast properties.
