Journal Textile Coloration and Finishing Year / Vol., Issue, Month 2014 / V.26,no.2,Jun Title The Physical Property of PET Coolness Knitted Fabric for High Emotional Garment Authors Hyun Ah Kim1, Ji Yoon Woo* and Seung Jin Kim Institution/Affiliations 1Korea Research Institute for Fashion Industry, Yeungnam University Pages/Total page pp.114 ~ 123 / 10 Language Korean Abstract This research investigated the physical properties of PET coolness filaments and their knitted fabrics including dyeing characteristics of these knitted fabrics according to the different dyeing time and temperature. The coolness filament(S) with non-circular cross-section and hydrophilic property was spun and another commercialized coolness(A) and regular(R) PET filaments were prepared for comparing coolness and another physical properties. Qmax of coolness knitted fabric made with S filament was higher than that of R-PET filament, and the maximum value of Qmax of S knitted fabric was shown at the dyeing conditions of temperature, 110℃ with 30 min. or 40min. It was shown that hand of S knitted fabric was a little harsh comparing to A and regular knit specimens, but shape retention and wearing performance of garment made with S knit specimen were estimated as good owing to high bending and shear rigidity. K/S of S knitted fabric was higher than those of regular PET and A knit specimens. Dyeing fastness of coolness knitted fabric showed between 4th and 5th grade.
