Abstract

This study examined the water and moisture vapor permeabilities and the heat retention rate related to the wear comfort of the woven fabrics made from different types of composite yarn, the sheath/core composite yarn structure and non-circular cross-section of the constituent filaments (Coolmax^®) in the core region played a very important role with high fabric porosity by including a capillary absorption in the wicking property. The fabric structures with high porosity composed of Coolmax^® sheath/core yarns, and spun yarns with non-circular cross-sectional fibers (Coolmax^®) affected strongly the fast drying rate due to moisture vapor diffusion of composite yarn fabrics. The moisture vapor permeability of the composite yarn fabrics was highly dependent on the porosity in the sheath/core yarn structures, In addition, the heat retention rate of the composite yarn fabric was strongly influenced by the high porosity due to the sheath/core and bulky staple yarn structures as well as the low thermal conductivity of the constituent fibers.

摘要

本研究考察了与由不同类型复合纱线制成的机织物的穿着舒适性、皮/芯复合纱线结构和组成长丝的非圆形横截面相关的水和湿气渗透率和保温率。 Coolmax ^® ) 在芯部区域发挥了非常重要的作用，通过在芯吸性能中包含毛细管吸收，具有高织物孔隙率。具有高孔隙率的织物结构由 Coolmax ^®皮/芯纱和具有非圆形横截面纤维的短纤纱 (Coolmax ^®) 由于复合纱线织物的湿气扩散，对快干速率影响很大。复合纱线织物的透湿气性高度依赖于皮/芯纱线结构的孔隙率，此外，由于皮/芯和膨松的高孔隙率，复合纱线织物的保温率受到强烈影响。短纱线结构以及组成纤维的低热导率。
