一种多功能超吸水海藻纤维的制备
摘要：
本发明公开一种超吸水海藻纤维的制备方法及所制得的多功能超吸水海藻纤维。该方法包括以下步骤：制备3-氯-2-羟丙基三甲基氯化铵，在将其配制成质量分数为50%的溶液，备用；将海藻酸钠溶于质量分数为5%的氢氧化钠水溶液中，制成海藻酸钠溶液；制备氯化钙凝固液；再通过改性修饰的方法，在海藻酸钠分子链上引入季铵化基团，最后湿法纺丝，得到多功能超吸水海藻初成纤维，再经过牵伸、水洗、卷绕、干燥和上油，进一步得到多功能超吸水海藻纤维。多功能超吸水海藻纤维与传统海藻纤维相比，具有良好的抑菌性、优异的吸水性，其吸水倍率是传统海藻纤维的2-3倍。
摘要（英）：

The invention discloses a multifunctional super-water-absorption alginate fiber preparation method and prepared multifunctional super-water-absorption alginate fiber. The method includes the following steps that 3-chlorine-2-hydroxypropyl trimethyl ammonium chloride is prepared into a solution with the mass fraction being 50% for use; sodium alginate tech grade is dissolved into a sodium hydroxide aqueous solution with the mass fraction being 5%, and an odium alginate tech grade solution is obtained; calcium chloride solidification liquid is prepared; through a modification and embellishment method, a quaternization group is introduced into a sodium alginate tech grade molecular chain, next wet spinning is conducted, and primary multifunctional super-water-absorption alginate fiber is obtained; next drafting, rinsing, winding, drying and oiling are conducted on the primary multifunctional super-water-absorption alginate fiber, and the multifunctional super-water-absorption alginate fiber is obtained. Compared with traditional multifunctional super-water-absorption alginate fiber, the multifunctional super-water-absorption alginate fiber has good antibacterial activity and excellent hydroscopicity, and the water absorbent rate of the super-water-absorption alginate fiber is 2 to 3 times that of the traditional super-water-absorption alginate fiber.
