림프부종 치료기능 압박 소매용 Double Covered Yarn 제조 기술에 관한 연구

초록

This study aimed to develop a double-covered yarn (DCY) for compressed sleeves used to treat lymphedema that may occur after surgery in breast cancer patients. To improve pressure sensation, instead of using the existing nylon 66 and spandex combination, the DCY covering manufacturing process was improved by using new spandex and nylon 6 in the fiber combination. In addition, to determine the effect of the manufacturing parameters of DCY, which is a compression yarn, the behavior of changes in tensile stress and tensile strain according to the DCY manufacturing parameters and the side image of DCY by SEM were investigated. As a result, when the draft ratio of the spandex fiber used as the core yarn of DCY increased, the elongation area of DCY that could be stretched at low stress decreased. Under the same draft ratio condition, changing the fineness of the second covering yarn or spandex fiber had little effect on the mechanical properties of DCY. In addition, it was confirmed that the effect of the fineness and draft ratio of the spandex fiber and the fineness of the second covering yarn on the tensile stress and tensile strain of DCY was not very significant. Furthermore, it was found that the fineness of the spandex fiber and the second covering yarn were affected more than the draft ratio of the spandex fiber.
