Based on the Friedel-Crafts alkylation reaction, epichlorohydrin is applied to decorate the meta aramid to enhance the comfort of the fabrics. It is obviously more perfect that the samples are treated with the hydrophilic soft finishing agent. In this paper, the effects of modification and finishing time on the structure and properties of meta aramid are studied. The results indicate that the surface roughness, polarity, active point, and wetting property of the modified fabrics are increased, and the loading rate and fastness of the finishing agent on the meta aramid are enhanced. After finishing, the wetting time and the time of water transfer from the surface to the bottom become shorter in the fabrics, and the water absorption rate becomes faster, the core absorption height rises by 60%, the bending stiffness lowers by 39%, the moisture permeability increases by 5.9%, the permeability decreases by 3.6%, and the friction electric voltage reduces by 78%, The longitudinal and weft secondary combustion time increase by 0.3 s and 0.2 s, the smoldering time increase by 0.3 s, and the improving rate of damage length are 5.4% and 7.6%, respectively.

芳纶的Friedel-Crafts烷基化改性和亲水性柔软整理

基于Friedel-Crafts烷基化反应,将环氧氯丙烷用于装饰间位芳纶,以提高织物的舒适度。显然,用亲水性柔软整理剂处理样品会更加完美。本文研究了改性和精制时间对间位芳纶结构和性能的影响。结果表明,改性织物的表面粗糙度,极性,活性点和润湿性均得到提高,并提高了间位芳纶上整理剂的负载率和牢度。整理后,织物的润湿时间和水分从表面到底部的转移时间变短,吸水率变快,纤芯吸收高度增加60%,弯曲刚度降低39%,
