초록

Cotton fabric md nylon fabric were chosen as base fabric specimens for dyeing using Japanese pagoda tree colorants through chitosan, treatment. With the chitosan treatment, the dye-uptake of the treated fabric increased. This treatment is also expected to be effective in terms of environment-friendliness. The effect of the dyeing methods, mordanting or non-mordanting, and chitosan treatment on the dye-uptake and air permeability of the treated fabrics was investigated. In case of cotton fabric, Al mordanted dyeing resulted in higher dye-uptake through the chitosan treatment. Therefore, the chitosan treatment is effective in this case. Japanese pagoda tree seems to have direct affinity for nylon fabric without the mordanting treatment. In case of cotton fabric, it seems that the cellulose molecules, colorants, and the chitosan make a complex, thereby reducing the air permeability. In case of nylon fabric, due to the fact the Japanese pagoda tree colorant molecules form direct physical bonding with the nylon molecules, it seems that there is not much of air permeability reduction.
