A study on the interdependence of fabric pore size and its mechanical and comfort properties

ABSTRACT

The study was conducted to investigate the effect of cotton woven fabric pore size on its mechanical and comfort properties. Using 20/1 Ne cotton yarn, 10 fabrics with varying pore size were produced in plain weave for this study. In order to get variable pore sizes, the thread density was changed along warp and weft direction, keeping the linear density of yarn as constant. It was observed that with increase in pore size, air permeability as well as moisture management increased but the thermal resistance decreased. In general, the comfort properties of cotton fabrics were improved with a higher pore size but for applications requiring heat retention, the fabrics having smaller pore sizes must be preferred. It was further observed that the mechanical properties of cotton fabrics do not depend directly on the pore size, rather they depend on the number of threads, in a particular direction. The number of threads may be controlled to get desired pore size and ultimately the desired properties.

摘要

研究了棉纤维织物孔径对织物力学性能和舒适性能的影响。本研究采用20/1的NE棉纱线，在平纹织物中织造出10种孔径不同的织物。为了获得不同的孔径，纱线的密度沿经纬方向变化，保持纱线的线密度不变。结果表明，随着孔径的增加，透气性和水分管理增加，但热阻减小。一般来说，棉织物的舒适性能得到改善，孔径更大，但对于需要保暖的应用，织物必须具有较小的孔径。进一步观察到，棉织物的机械性能不直接取决于孔径，而是取决于螺纹的数量，在特定的方向上。可以控制螺纹的数量以获得所需的孔径并最终达到所需的性能。
