Journal Textile Coloration and Finishing Year / Vol., Issue, Month 2019 / V.31,no.4,Dec Title A Study on the Physical Properties of Double Raschel Pile Fabric according to Heat Treatment Authors Eun Jong Son*, Hong Won Park1 and Young Gu Hwang2 Institution/Affiliations Bucheon University, 1Korea High Tech Textile Research Institute, 2Duck San Enterprise Pages/Total page pp.288 ~ 297 / 10 Language Korean Abstract The specimens were heat treated at 180℃, 190℃, 200℃, 210℃ and 220℃ to observe the change of the physical properties of the double raschel pile fabric. The density, tensile strength, weight, elongation, dyeing characteristics, fabric surface morphology and cross sectional shape were observed by heat treatment temperature. Compared with untreated samples, weight, density and tensile strength were increased with increasing heat treatment temperature. No increase was observed at 220℃. In the case of elongation, it increased to 190℃ but thereafter it could not be observed. In the case of uprightness of brushed hair, it was observed that the gap between the yarns was narrowed and the density was increased and the straightness of the yarn and pile yarn was improved by widening the heat treatment temperature. As a result, it was observed that the uprightness was remarkably improved and the bulky properties was increased. It was also observed that the increase of the dyeability was observed with increasing the heat treatment temperature.
