ABSTRACT

This study examined the pretreatment effect, appropriate dyeing conditions, color fastness and functionality ofcotton fabrics dyed with Zizania latifolia Turcz. Dye uptake was substantially increased by pretreatment and chitosanpretreatment was much more effective than tannic acid pretreatment. Optimal dyeing conditions were colorant concentrationof 100%, dyeing temperature of 100℃, dyeing time of 80 minutes and dyebath pH of 5.5. Color fastness of chitosanpretreatment and dyed cotton to washing, rubbing, perspiration and light was 4, 5, 3-4(acidic), 3(alkaline) and 3 respectively. Color fastness of tannic acid pretreatment and dyed cotton to washing, rubbing, perspiration and light was 4, 5, 3-4(acidic),4-5(alkaline) and 4 respectively. Deodorization rates of ammonia(NH3) were 99.9% in both cases. UV protection rate were98.3% of UV-A and 98.5% of UV-B in case of chitosan pretreatment. UV protection rate were 98.2% of UV-A and 98.5%of UV-B in case of tannic acid pretreatment. UV protection factor(UPF) was 50+ in both cases. Reduction rate of Staphyloccusaureus were 99.9% in both cases. Therefore Zizania latifolia Turcz. could be used a new functional colorant.
