Thermo-physiological Clothing Comfort of Wool-Cotton Khadi Union Fabrics

ABSTRACT

Khadi is a handspun and handloom woven textile fabric made up of natural textile fibers, predominantly cotton and wool. Khadi mainly intended for apparel purposes. Hence, the thermo-physiological properties of wool-cotton blended khadi fabric are crucial in studying fabric comfort. In this study, the 18 types of wool-cotton blended khadi fabrics are produced on a handloom by using wool-cotton blended yarn as warp; and woolen yarn comprised of three different mixes of Australian Merino (AM) wool and JK crossbred (JKC) as weft yarn. Two different weft yarns of 41.7 and 31.2 Tex were prepared using these mixes. The thermo-physiological properties of fabric viz. air permeability, water vapor transmission, and thermal resistance were studied. The air and water vapor permeability, and thermal resistance of wool-rich blended fabrics were found higher compared to cotton-rich blends. The air permeability is negatively influenced by the fabric cover factor. The coarser weft yarn gives higher air permeability while lower water vapor permeability. The thermal resistance is found to have a positive relationship with fabric cover factor. The wool content in yarn and weft yarn linear density largely influences the thermo-physiological comfort properties of the khadi fabric.

摘要

卡迪是一种由天然纺织纤维 (主要是棉和羊毛) 制成的手摇和手摇纺织面料. 卡迪主要用于服装用途. 因此, 毛棉混纺卡迪织物的热生理特性是研究织物舒适性的关键. 本研究以毛棉混纺纱为经纱, 在手摇织机上生产了18种毛棉混纺卡迪织物; 以及由三种不同的澳大利亚美利奴 (AM) 羊毛和JK杂交 (JKC) 混合而成的纬纱. 使用这些混合物制备了两种不同的41.7 Tex和31.2 Tex纬纱. 织物的热生理特性, 即. 研究了透气性, 水蒸气透过率和热阻. 与富棉混纺织物相比, 富毛混纺织物的透气性, 透湿性和耐热性更高. 透气性受到织物覆盖系数的负面影响. 较粗的纬纱具有较高的透气性, 而较低的水蒸气透气性. 热阻与织物覆盖系数呈正相关. 纱线中羊毛含量和纬纱线密度在很大程度上影响卡迪织物的热生理舒适性.
