Abstract

It is essential to achieve the optimum stretch for the 100% cotton woven compression bandage (WCB), particularly when producing short-stretch bandage (SSB). Since the SSB achieves a high level of working pressure (dynamic or walking) and a low level of resting pressure (supine or sleeping), this study evaluated the effect of ply twist on yarns extension that are being used as warp yarns in WCB. The proposed study investigated the commercial yarns available in the bandage market in addition to yarns spun at a wider range of ply twist. Moreover, the study analysed the influence of yarn material and bandaging technique on corresponding pressure at the ankle and mid-calf positions. Results revealed that the optimum twist for plied yarn should be at least 1800 turns per meter to produce highly extensible WCB. The experimental results of the uniaxial stress test concluded that the elasticity of 100% cotton short-stretch bandage followed the exponential behaviour whereas the cotton-polyamide-polyurethane long-stretch bandage behaved in a linear function due to the higher level of elastic recovery gained by polyurethane (Elastane) filament.

摘要

为 100% 棉机织压缩绷带 (WCB) 实现最佳拉伸至关重要，特别是在生产短弹力绷带 (SSB) 时。由于 SSB 实现了高水平的工作压力（动态或行走）和低水平的静息压力（仰卧或睡眠），本研究评估了合股捻度对 WCB 中用作经纱的纱线延伸的影响。拟议的研究调查了绷带市场上可用的商业纱线，以及以更广泛的合股捻度纺制的纱线。此外，该研究分析了纱线材料和包扎技术对脚踝和小腿中部相应压力的影响。结果表明，合股纱的最佳捻度应至少为每米 1800 转，以生产高延展性 WCB。
