N2 - In this study, Tencel staple fibers and PET low melting point fibers (LMPET) were blended to prepare composite nonwovens, with change of blending ratio of Tencel/LMPET, hot-baking time and temperature. By measurement of mechanical properties, the optimal parameters were found to become dressing covering material after analysis of experimental data, with adjustment of strength, breathability and flexibility of nonwovens. During membrane preparation, 3 % chitosan solution was exposed to UV ray for 1, 3, 5 minutes, and then manufactured into membrane by Freeze Dryer, in order to explore broken bond whether happened on chitosan structure and to further manage chitosan membrane degradation rate. With analysis of UV irradiation time influencing on membrane releasing, membrane at the same size was immersed in PBS for degradation test. According to mechanical and degradation results, it is showed that, 100 % Tencel nonwovens had better breathability and strength than that mixed with 30 % LMPET, and membrane had the most stable degradation rate after 5 min irradiation of chitosan solution. Finally, using most stable chitosan and Tencel nonwovens, Tencel/ Chitosan composite dressing fabric was compounded by coating.
