摘要:

EKS纤维是一种具有显著吸湿发热性能的亚丙烯酸盐系纤维。对比了EKS纤维和腈纶纤维的表面形态,测试与分析了两种纤维的力学性能、摩擦性能、比电阻、卷曲性能、吸放湿性能及吸湿发热性能。结果表明,相比于腈纶纤维,EKS纤维横截面为圆形,纵向结构粗糙,具有断裂强度、摩擦系数、比电阻和卷曲率小,线密度、断裂伸长率和回潮率大等特点。EKS纤维的吸、放湿速率随时间呈指数形式衰减,纤维的初始吸、放湿速率分别为0.39% min-1、8.94% min-1,达到吸、放湿平衡所用时间比腈纶纤维长。EKS纤维具有较好的吸湿发热性,吸湿发热最高升温值为8.2 ℃,比腈纶纤维高4.7 ℃。

Abstract:

EKS fiber is a subacrylate fiber with significant hygroscopic-heating properties. In this study, the surface morphologies of EKS and acrylic fibers were compared, and their mechanical properties, friction properties, specific resistance, curling properties, moisture absorption and liberation properties, and hygroscopic-heating properties were tested and analyzed. The results showed that compared with the acrylic fiber, the EKS fiber featured a circular cross section and rough longitudinal structure as well as low breaking strength, friction coefficient, specific resistance and curl rate; moreover, it featured a high linear density, elongation at break, and moisture recovery rate. With the initial absorption rate and liberation rate being 0.39% min-1 and 8.94% min-1, respectively, the moisture absorption and liberation rates of the EKS fiber decreased exponentially with time, and the time required to achieve the absorption and liberation balance was longer than that for the acrylic fiber. The EKS fiber exhibited good hygroscopic-heating properties with a maximum hygroscopic-heating value of 8.2 ℃, which was 4.7 ℃ higher than that for the acrylic fiber.

Key words: EKS fiber, acrylic fiber, morphological structure, performance testing, hygroscopic-heating, moisture absorption and liberation properties
