ABSTRACT

Demands for nylon suede as an artificial leather are increasing due to its functionality and aesthetics. To achieve high value added nylon suede based on green technology, this study was carried out in order to obtain useful data for the nylon suede fabrics with eco-friendly dyeing process by a pad-steam method instead of a dip dyeing process using sulphur black dye to reduce the industrial waste of water. The dyeability of the nylon suede was investigated according to reducing temperatures, dye concentrations, and reducing agent’s concentrations. Throughout the results of the CIE L*a*b* and Munsell values, the optimized dyeing conditions of the nylon suede using sulphur black dye are 70℃ of dyeing temperature, 30% o.w.f. of dye concentration, and 9g/ℓ of reduction agent concentration, respectively. Furthermore washing colorfastness, light colorfastness and perspiration colorfastness were achieved in the range of 4-5 grades.
