以戊二醛为增强改性剂，利用湿法纺丝制备含有预埋增强剂的南极磷虾蛋白/海藻(AKP/SA)初生纤维，通过初生纤维纺丝线在线热交联技术实现热交联反应从而制得高强度南极磷虾蛋白/海藻(HAKP/SA)复合纤维。利用旋转黏度计确定了增强交联反应的热交联温度，研究了交联度对复合纤维微观结构以及吸湿性能的影响，测试了增强后复合纤维力学性能和结晶性能的变化。结果表明：80℃时戊二醛能有效发生热交联反应；AKP/SA复合纤维具有较好的吸湿性能，吸湿率为7.3%，随着交联度的提高，复合纤维的吸湿性能降低，吸湿平衡时间缩短；HAKP/SA复合纤维仍以非晶形态存在，表面存在不均匀的沟槽结构；力学性能测试表明增强后的纤维断裂强度提高了13%。
Act glutaraldehyde as enhance modifier to prepare primitive Antarctic krill protein/sodium alginate (AKP/SA)primary fibers using wet spinning process,and the high strength Antarctic krill protein/algae (HAKP/SA)composite fibers were fabricated via online thermal crosslinking technology realizing thermal crosslinking reac-tion through primary fiber spinning line.Thermal crosslinking temperature was defined by Rotational viscometer. The effects of crosslinking degree on microstructure and moisture absorption performance of composite fiber were studied,and the variations of mechanical properties and crystallization properties of composite fiber after reinforce-ment were tested.The results show that glutaraldehyde can perform effective thermal crosslinking reaction when temperature is 80 ℃.AKP/SA composite fiber has good moisture absorption performance,moisture absorption rate of 7.3%,the moisture absorption performance of composite fiber decreases and moisture balance time shortens with the increase of crosslinking degree.HAKP/SA composite fiber still exists in amorphous form.Surface of composite fiber shows uniform groove microstructure.Mechanics performance test shows that the fiber breaking strength after reinforcement increases by 1 3%.
