Journal Textile Coloration and Finishing Year / Vol., Issue, Month 2022 / V.34,no.3,Sept Title Dyeing Properties of Functional PET Double Knit Fabric Authors Bum Hoon Lee Institution/Affiliations Shinhan University Pages/Total page pp.146 ~ 156 / 11 Language Korean Abstract In this study, the dyeing properties of double knit fabric composed of PET/PTT bi-component fiber and quick dry fiber were examined with disperse dyes. In addition, the shrinkage characteristics were investigated during the dyeing process. The K/S values and shrinkage rate of PET/PTT bi-component fiber were higher than those of PET/co-PET bi-component fiber and quick dry fiber. In the dye bath, dye migration of exhausted on PET/PTT bi-component fiber to quick dry fiber was found at high dyeing temperature. It was not found that there was a significant difference in K/S value on dyeing temperature between 115℃ and 130℃. But the slight color difference of two sides of a double knit fabric was found.
