摘要：

为准确检测织造载荷作用前后浆纱的毛羽及有效表征浆纱的抗起毛性能,提出一种基于毛羽量图像检测的浆纱抗起毛性能评价方法。对纯棉14.5 tex的原纱和3种不同上浆率的浆纱,在JN-01浆纱耐磨性能测试仪上模拟织造载荷,并进行不同载荷次数的摩擦起毛实验。起毛后的纱线经图像采集、纱线主干分割、毛羽分割和主摩擦区间定位等处理后,提取纱线的毛羽量指标;同时,构建浆纱毛羽量与织造载荷作用次数的对数函数模型,并基于此模型提出评价浆纱抗起毛性能的综合指标纱线起毛指数。结果表明,所提出的方法可以准确检测纱线的毛羽量,同时纱线起毛指数能有效表征在织造载荷下经纱的抗起毛性能。

Abstract:

In order to evaluate accurately the hairiness of sized yarns before and after weaving and characterize effectively the anti-pilling performance of sizing, an evaluation method of anti-pilling performance of sized yarns based on image detection of hairiness was proposed. Cotton raw yarns of 14.5 tex and sized yarn with three types of sizing add-ons were studied to simulate weaving load on JN-01 sizing abrasion resistance tester, and abrasion resistance experiments were carried out. Based on image acquisition, yarn evenness segmentation, hairiness segmentation and main abrasion zone positioning, the hairiness index was extracted. The logarithmic function model of sizing hairiness and weaving load was established, and the comprehensive yarn pilling index is constructed based on this model. The results show that the proposed image method can accurately identify the yarn hairiness, and the yarn pilling index can effectively characterize the anti-pilling performance of the sized yarns under various weaving loads.

Key words: sized yarn, weaving load, regenerated hairiness, image detection, hairiness detection, pilling index, anti-pilling performance
