The influence of heat treatment on sorptional and mechanical properties of viscose: polypropylene (90:10) blend nonwoven fleeces has been studied. It is observed that the heat treatment improves mechanical properties (rupture resistance and tensile strength) and slightly decreases sorptional properties (degree of water retention and rate of water absorption) of cloths. The optimum heat-treatment temperature needed to obtain the highest breaking force and water absorption of nonwovens is found to be 165-170ºC. Microstructural analysis proves that the nonwovens have the point bonding form of web when heat treatment is performed at optimum temperature.
