牛仔织物性能检测摘要随着科技的进步和纺织行业的发展,合身舒适、伸展自如的弹力织物已经应用到服装的各个领域,尤其是弹力牛仔织物的市场需求很大。本文设计并织制一系列不同纬密的的弹力牛仔面料,通过对其力学性能和保形性能的检测及分析,研究牛仔织物中纬密与纬向力学性能、保形性能之间的关系。关键字：牛仔织物；性能；棉双丝弹力包芯纱；纬密abstract: With the progress of science and technology and the development of textile industry, elastic fabrics with comfortable fit and easy extension have been applied to various fields of clothing, especially elastic jeans, which have a great market demand. In this paper, a series of elastic denim fabrics with different weft densities are designed and woven. The relationship between weft densities, weft mechanical properties and shape retention of denim fabrics is studied by testing and analyzing their mechanical properties and shape retention properties.Key words: denim fabric; performance; cotton twin-filament elastic core-spun yarn; weft density目录引言：..............................................................3一、研究背景及意义..................................................3二、牛仔织物性能实验................................................42.1 实验材料........................................................42.2 试样准备....................................................42.3 织物性能测试.................................................52.3.1 织物的纬向拉伸性能.....................................52.3.2 织物纬向弹性试验.......................................52.3.3 织物折皱回复性实验.....................................52.3.4 织物的纬向刚度和柔度试验...............................5三、牛仔织物的性能考核指标..........................................63.1 外观缺陷.....................................................63.2 染色牢度.....................................................63.3 成品的宽度和表面密度.................................
