摘　　要：针对超细纤维合成革强力低、易变形、变形后回复性差等问题,以海岛纤维为研究对象,分别采用氢氧化钠和盐酸溶液对碱溶性涤纶/锦纶6(COPET/PA6)海岛纤维进行碱减量处理和酸减量处理,得到PA6岛组分与藕状中空COPET海组分。分析了各组分的拉伸性能、松弛性能和蠕变性能,并对其黏弹性进行指数拟合,探讨各组分与海岛纤维拉伸性能之间的关系。结果表明:COPET/PA6海岛纤维的强伸性能和变化趋势基本与PA6岛组分的相一致,并符合混合律;COPET海组分的抗松弛蠕变性能较好,而PA6岛组分的较差,并直接影响到COPET/PA6海岛纤维的抗松弛性能和抗蠕变性能。In order to solve the problems of low strength,easy deformation and poor recovery after deformation of the superfine fiber synthetic leather,taking the sea island fiber as the research object,the alkali-soluble polyester/polyamide 6(COPET/PA6)sea island fiber was treated with NaOH and HCl solution to obtain the PA6 island component and lotus-shaped hollow-core COPET sea component.Tensile properties,relaxation properties and creep properties of COPET/PA6 sea island fibers,PA6 island components and COPET sea components were measured and analyzed.The viscoelasticity was fitted exponentially.The relationship of tensile properties between components and sea island fiber was discussed.It is concluded that the tensile properties and the change trend of COPET/PA6 sea island fibers are substantially consistent with those of PA6 island and accord with the mixing law.The COPET sea component possesses good anti-relaxation creep properties,while those of the PA6 island components are poor,which directly affect the relaxation resistance and creep resistance of the COPET/PA6 sea island fiber.
