ABSTRACT

This study investigated the physical properties of warm up yarns and their knitted fabrics including the dye affinity and color fastness to washing of these knitted fabrics according to the various dyeing times and temperatures on dyeing process. The results were summarized as follows. The tenacity of Nylon/PP warm-up yarn was 4g/d and breaking strain was 4.5%. The wet and dry thermal shrinkages were higher than those of PET warm-up yarn. The maximum heat flow rate(Qmax) of Nylon/PP warm-up knitted fabric was lower than that of PET warm-up knitted fabric and heat keeping rate(a) of Nylon/PP warm-up knitted fabric was higher as 47% than that of PET warm-up knitted fabric. It was shown that the shape retention and wearing comfort of Nylon/PP warm-up knitted fabric were better than those of PET warm-up knitted fabric. The dye-affinity(K/S) of Nylon/PP warm-up knitted fabric showed maximum value at the dyeing condition of 40minute or 50minute dyeing time with 80℃ dyeing temperature, but PET warm-up knitted fabric showed maximum value at the 30minute or 40minute with 110℃ dyeing temperature. Finally, the color fastness to washing of Nylon/PP warm-up knitted fabric showed good value as between 4 and 5 grade.
