摘　　要：为拓展天然颜料在海藻纤维原液着色领域的应用,以乌贼墨黑色素(ME)为着色剂,采用海藻酸钠(SA)稀溶液作为研磨助剂和分散剂,制备了乌贼墨海藻酸钠(ME-SA)纺丝液,并制得有色海藻纤维。借助红外光谱仪、流变仪和透射电子显微镜对纺丝液的性能进行表征,利用扫描电子显微镜观察制得纤维的形貌,并测试了纤维的紫外线屏蔽性能。结果表明:ME与海藻酸钠具有良好的相容性,研磨和稀海藻酸钠的助研避免了ME纳米颗粒的团聚现象,实现了ME的稳定分散;海藻纤维的形貌未受ME的影响,ME添加量为3%的着色海藻纤维对紫外光的平均屏蔽效果达75%以上,对高能量的短波紫外线的屏蔽效果可以达到85%。In order to expand the use of natural pigments in the dope-dyed alginate fiber,dope dyeing spinning solution and alginate fiber were prepared using sepia melanin(ME)as colorant and sodium alginate(SA)dilute solution organic grind auxiliary agent and dispersant.The performance of the spinning fluid was characterized by the infrared spectrometer,the rheometer and the transmission electron microscope.The mography of the fibers was observed by scanning electron microscope,and the ultraviolet shielding properties of the fibers was measured.The results show that ME and the sodium alginate have good compatibility.The agglomeration of ME nanoparticles is eliminated by grinding and diluting sodium alginate,achieving the stable dispersion of ME.The morphology of alginate fibers is not affected by ME.The dope-dyed alginate fiber containing 3%ME achieves more than 75%average ultraviolet light shielding,and the shielding of high-energy short-wave ultraviolet light reaches 85%.
