스판덱스 코어 나일론 커버링 two way 복합사 직물의 전단특성
李春吉 慶一大學校 2002 論文集 Vol.18 No.-
The two way fabrics woven by spandex-core nylon-covering complex yarn play a decisive role in producing the high quality textile garments. The fabrics used in this experiments, woven by polyurethane 40 denier core filament and nylon 140 denier/ 48 filaments covering yarn, were wet and dry heat treated two way fabrics. We performed the experiments to know the influence of treatment time and temperature on the shear properties of the two way fabrics. In wet treatment, the samples were made by using the two way fabric at boiling temperature through the treatment time of 2, 4, 6, 8, 10 min. respectively. In dry treatment, the samples were made at the temperature of 100, 120, 140, 160℃ for 2, 6, 10, 20 min. respectively. The shear properties of the samples were evaluated by using Kawabata Hand Evaluation System. Through the experiments the following results were obtained. The shear stiffness of the wet treated samples increased according to the treatment time and the shear stiffness of the dry treated samples decreased at the treatment temperature of 160℃ according to the treatment time. The hysteresis of shear force at the shear angle φ=0.5° of the wet treated samples decreased and the hysteresis of shear force at the shear angle φ=0.5° of the dry treated samples decreased at the treatment temperature of 160℃ according to the treatment time. The hysteresis of shear force at the shear angle φ=5°of the wet treated samples had almost the same values but the hysteresis of shear force at the shear angle φ=5°of the dry treated samples decreased over the treatment temperature of 120℃ according to treatment time.

CDP사와 PU사를 사용한 고밀도 양방향 신축성 편물의 전처리 및 염색 특성에 관한 연구
조항성,우장창,이범수 한국염색가공학회 2022 韓國染色加工學會誌 Vol.34 No.4
Recently, consumer tastes of various classes at home and abroad prefer comfortable, unadorned, and simple clothing, and the athleisure trend, which can be used freely in daily life as well as exercise, has expanded to overall clothing products. 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.
