Abstract

Fabric surface hairiness has a decisive effect on the fabric processing performance and the resultant garment quality. In practice, current testing of fabric hairiness still cannot be conducted like the routine testing of yarn hairiness. With the aim of conducting fabric hairiness testing routinely, a novel method of testing woven fabric belt hairiness was proposed in this study, using a yarn hairiness meter. For practical experiments, a woven fabric sample was firstly slit and then the slit sections were connected as a continuous belt. A belt support and some belt guides were applied to guarantee the continuous feeding of the belt into a yarn hairiness detector zone, where the belt surfaces were vertical to the laser emissioner and the hairiness detector surfaces. Consequently, hairiness of both surfaces of the belt was projected and fully mapped on the detector surface. Experimental results showed that the fabric belt hairiness was successfully tested in terms of the hairiness length, number and distributions; fabric belts with different hairiness levels before and after hair-cutting could be effectively identified. In particular, the representative true hairiness of the woven fabric belt could be calculated by subtracting the tested hairiness value of 3 mm wide belt to that of 2 mm wide belt. Comparative analysis indicated that our method was more suitable for routine testing of woven fabric hairiness than other current methods.

摘要

织物表面毛羽对织物加工性能和最终成衣质量具有决定性影响。在实践中，目前的织物毛羽检测还不能像纱线毛羽的常规检测那样进行。为了定期进行织物毛羽检测，本研究提出了一种使用纱线毛羽计检测机织物带毛羽的新方法。在实际实验中，首先将机织物样品切开，然后将切开的部分连接成一条连续带。皮带支架和一些皮带导向器用于保证皮带连续送入纱线毛羽检测器区域，皮带表面垂直于激光发射器和毛羽检测器表面。最后，带的两个表面的毛羽被投影并完全映射在探测器表面上。实验结果表明，织物带毛羽在毛羽长度、数量和分布等方面的测试成功；可以有效识别剪毛前后不同毛羽级别的织物带。特别是机织带的代表性真毛羽数减去测试的毛羽数为3即可。 毫米宽的皮带到 2 毫米宽的皮带。对比分析表明，与现有的其他方法相比，我们的方法更适合于机织物毛羽的常规检测。
