摘要
针对间位芳纶织物导湿排汗性能差而影响穿着舒适性的问题,采用酸性高锰酸钾和等离子体2种改性方法分别处理芳纶织物,并对改性后的织物进行导湿排汗整理。结果表明:酸性高锰酸钾改性后纤维表面裂痕较深且数量较多,质量损失较大;等离子体改性后表面含有更多的氧元素和极性基团,整理后其含量进一步提高,其中羟基含量增加最多;改性后断裂强力和断裂伸长率略有下降,整理后有所回升;整理后织物的回潮率增大,导湿性、透湿性、透气性及抗静电性均得到改善;改性后再整理织物的耐洗性明显好于未改性仅整理的织物;改性和整理均不会损害织物的阻燃性,阻燃性反而有所提高。
In order to improve the poor performance of moisture absorption and sweat transport affecting comfortability of meta-aramid fabrics,two methods of modification with acidic potassium permanganate and plasma were used,respectively,and after that moisture absorption and sweat transpont finishing were operated.The results show that the surface cracks of the modified fibers by acidic potassium permanganate are deeper and more,and the loss of weight is higher.The surface of the modified fibers by plasma contains more oxygen elements and polar groups.The content is further increased after finishing,and the largest increment occurs in hydroxyl.The strength and elongation at break decrease slightly after modification,and then increase slightly after finishing.The moisture regain increases,and the moisture conductivity,moisture permeability,air permeability and antistatic property are all improved after finishing.Washability of modified fabrics is obviously better than of unmodified fabrics.Modification and finishing don＇t damage the flame retardancy of fabrics.On the whole,the flame retardancy is improved.
