Kawabata Analysis of Cotton Denim Fabrics Treated with Industrial Washing Techniques

ABSTRACT

Garment washing of denim fabrics is essential for fading of color, aesthetic effects, vintage look and improvement in handle properties of resulting garments. Denim fabrics of two types, one standard fabric (non-stretch) and other with 2% elastane fiber (stretch), are washed with different industrial washing techniques on Tonello sampling machine. The objective evaluation of handle and mechanical properties of the washed samples are carried out on Kawabata evaluation system (KES-F). Five main characteristics of fabrics are evaluated on KES-F system. The mechanical properties like tensile energy, extensibility and compression energy have increased for both stretch and non-stretch fabrics, while bending stiffness and bending hysteresis have decreased for both types of washed fabrics. The geometrical surface roughness and coefficient of friction have slightly increased after employed washing techniques. The optical microscope is used to investigate the surface changes of the fabric after the employed washing techniques.

摘要

牛仔布织物的服装洗涤对于褪色、审美效果、复古外观和改善最终服装的手感性能至关重要. 在意大利Tonello采样机上, 采用不同的工业洗涤技术洗涤两种类型的牛仔布,一种是标准织物,（无拉伸）,另一种是含2%弹性纤维,（拉伸）. 在川端康成评估系统（KES-F）上对清洗后的样品进行了把手和机械性能的客观评估. 在KES-F系统上对织物的五个主要特性进行了评价. 拉伸织物和非拉伸织物的拉伸能、延展性和压缩能等力学性能都有所提高,而两种水洗织物的弯曲刚度和弯曲滞后性都有所降低. 采用清洗技术后,几何表面粗糙度和摩擦系数略有增加. 光学显微镜用于研究所用洗涤技术后织物的表面变化.
