Abstract
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.
