Sericin Grafting onto Cashmere Fiber and Its Properties Investigation
Cashmere fiber is pretreated with oxygen low temperature plasma to increase the content of polar groups (-OH, -COOH) on the surface. Then by using aziridine crosslinker and polycarbodiimide crosslinker, the sericin with health-care function is grafted onto the surface of the pretreated cashmere fibe...

| 总结: | Cashmere fiber is pretreated with oxygen low temperature plasma to increase the content of polar groups (-OH, -COOH) on the surface. Then by using aziridine crosslinker and polycarbodiimide crosslinker, the sericin with health-care function is grafted onto the surface of the pretreated cashmere fiber. Plasma treatment is optimized after the assessing of methylene blue staining and fiber tensile strength. The grafting rate of sericin indicates that both aziridine and polycarbodiimide crosslinker could play a bridging role. Compared with untreated fiber, oxygen plasma treatment can improve the grafting rate significantly. The chemical changes and morphological structures of the fiber surface are analyzed by infrared spectroscopy and scanning electron microscope. After modification, cashmere exhibited good antibacterial and antioxidant properties. In addition, the fiber still has excellent dyeability while its crimp property and whiteness are slightly reduced. |
