Abstract:

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. treatment,and then we made moisture wicking finishing. The results show that the surface cracks of the modified fibers bu 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 peoperty 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 whole, the flame retardancy is improved. 

Key words: meta aramid, moisture absorption and sweat transport finishing, acidic potassium permanganate, plasma, comfortability, flame retardancy
