Investigation of Thermo-Physiological Comfort and Mechanical Properties of Fine Cotton Fabrics for Ladies’ Summer Apparel

ABSTRACT

Fine cotton fabrics such as “Lawns” for ladies’ apparel are extremely popular in the subcontinent and all those parts of the world where summers are scorching and the subsequent rainy seasons quite hot and humid. The required fabrics should neither be too thin to be weak nor too thick to be uncomfortable. The main objective of this study was to investigate thermo-physiological comfort and mechanical properties of cotton fabrics ranging from approx. 50 to 80 g/m² areal densities (GSM) using 80, 70, 60, and 50 Ne yarn counts and to determine optimum fabric parameters for good fabric comfort and strength. Fabric of a specific areal density could be developed either by using coarser yarn counts with lower number of ends and picks per inch or by using finer yarn counts with higher number of ends and picks per inch. Results show that fabric of a specific areal density produced from coarser yarns with lower number of ends and picks results in better fabric air permeability and better tear strength, as compared to that made from finer yarns with higher number of ends and picks per inch. However, fabric thermal and water vapor resistance are not significantly affected by either approach used for the range of fabrics produced in this study. Based on response surface optimization, the optimum fabric parameters were found to be 60 Ne warp count, 50 Ne weft count, 90 ends/inch and 50 picks/inch for simultaneously achieving good fabric air permeability and strength properties.

摘要

精致的棉织品，如女装用的“草坪”，在次大陆和世界上所有那些夏天炎热，随后的雨季湿热的地方都非常流行.所需的织物既不能太薄，也不能太薄，使人不舒服.本研究旨在探讨棉织物的热生理舒适性及力学性能.50至80g/m2的面积密度（GSM），使用80、70、60和50ne纱线计数，并确定最佳织物参数，以获得良好的织物舒适性和强度.具有特定区域密度的织物可以通过使用较粗的纱线支数（每英寸的纱线支数和纬纱根数较低）或使用较细的纱线支数（每英寸的纱线支数和纬纱根数较高）来开发.结果表明，与每英寸纱线和纬纱根数和纬纱根数较高的细纱相比，粗纱和纬纱生产的比表面积密度更大的织物，具有更好的透气性和撕裂强度.然而，织物的耐热性和耐水蒸气性不受本研究所用织物系列的任何一种方法的显著影响.基于响应面优化，织物的最佳参数为60ne经纱数、50ne纬纱数、90头/英寸和50纬/英寸，以同时获得良好的织物透气性和强度性能.
