Existing materials used for athleisure are composite knitted fabrics using polyester yarn and PU yarn, which has problems due to a chronic lack of color fastness and contamination by dyes even when PU laminating is applied, making it difficult to apply various colors. There is a quality problem in which deformation of the product occurs due to lack of durability. In this study, CDP yarn(75de/72f) and PU yarn(40de) were selected to commercialize the circular knitting for athleisure using CDP yarn in order to solve the problems that occur in the dyeing and laminating process when using polyester materials. CDP yarns were used to knit into single(CP75-S) and double( CP75-D) knit and single knit were found to be suitable as athleisure fabrics. After pretreatment and treatment under various conditions, the stainability of CDP circular knitting was examined. After pretreatment and dyeing process under various conditions, the property of scouring and dyeability of CP75-S were evaluated.
