Effect of different softeners and sanforising treatment on pilling performance of polyester/viscose blended fabrics

An 80:20 polyester/viscose blended woven fabric was subjected to different softening and sanforising treatments. The effect of different softeners and sanforising treatments on the pilling propensity of the fabric was investigated. It was found that, while some types of softeners had no effect on pilling, the others may result in extreme deterioration of the pilling performance of polyester/viscose blended fabrics. It was further found that, in all cases, sanforising after softening adversely affects the fabric pilling performance.
