Abstract

Titanium dioxide (TiO 2) has been found feasible to improve wrinkle resistant property of cotton fiber. In this study, the performance of TiO 2 wrinkle resistant treatment was further enhanced by plasma pre-treatment compared with the conventional wet treatment. Different plasma pre-treatment process parameters (treatment speed, i.e. treatment time; oxygen flow rate; and jet-to-substrate distance) were used for determining the optimum conditions (of plasma pre-treatment) for the subsequent wrinkle resistant treatment with TiO 2. The optimum conditions for plasma pre-treatment of cotton fabrics before TiO 2 treatment were obtained through the orthogonal array testing strategy (OATS): 10mm/s treatment speed, 0.3L/min oxygen flow rate and 6mm jet-to-substrate distance. This was found to be the most effective combination of plasma pre-treatment conditions for improving wrinkle resistant property of cotton fiber. After plasma, if the cotton fiber was treated with 0.1% TiO 2, the wrinkle resistant property was further enhanced. Based on the OATS analysis, not only the optimum conditions for plasma pre-treatment could be obtained, but the level of relative importance of the three process parameters could also be obtained.
