The study investigated and analyzed the contamination of the fabric surface due to cotton waste yarn woven into the weft. The impact of cotton waste proportion and cleaning methods on open-end rotor yarn quality, using blends from 100 to 0% cotton waste mixed with virgin cotton fibers were investigated. The study proves that cotton waste can be effectively incorporated into yarn production without significantly compromising fabric properties, supporting the sustainable use of recycled fibers. The innovative cleaning channel W increases fiber yield but also raises contamination levels, leading to a higher number of detected impurities on the fabric surface. The classification method for dust and trash particles significantly affects the contamination evaluation, though contamination trends remain consistent. The classification of dust and trash particles by the maximal Ferret's diameter is preferred based on the obtained outputs from the realized experiment. Additionally, while the size of dust particles decreases as the cotton waste proportion decreases, trash particle size is unaffected by the cleaning channel or waste ratio in the weft yarn. In the case of the binary portion, contaminant levels decrease as cotton waste content in weft yarns is reduced, with the lowest found in cleaning channel A, followed by C and W. Surprisingly, dust and trash particles contribute to the binary portion equally. It leads to the recommendation connected with optimizing fabric quality, the final treatment should focus mainly on eliminating the visual impact of larger contaminants. The reason is that smaller particles can be mostly removed during pretreatment because they are not firmly fixed in a woven structure. The results also highlight the link between fabric contamination and potential health risks from respirable dust particles in the workplace, underscoring the need for effective control during processing to protect workers and ensure stable production not only in weaving but also in the following processes.
该研究调查并分析了因废棉纱织入纬纱而导致的织物表面污染情况。研究了废棉比例和清洁方法对转杯纺纱质量的影响，使用了100%至0%的废棉与原棉纤维混合的混纺物。该研究证明，废棉可以有效地融入纱线生产，而不会显著损害织物性能，支持了回收纤维的可持续利用。创新的清洁通道W提高了纤维产量，但也提高了污染水平，导致织物表面检测到的杂质数量增加。灰尘和杂质颗粒的分类方法对污染评估有显著影响，尽管污染趋势保持一致。根据实验结果，基于最大费雷特直径对灰尘和杂质颗粒进行分类是首选。此外，虽然灰尘颗粒的尺寸随着废棉比例的降低而减小，但杂质颗粒的尺寸不受清洁通道或纬纱中废棉比例的影响。在二元部分的情况下，随着纬纱中废棉含量的减少，污染物水平降低，在清洁通道A中发现的污染物水平最低，其次是C和W。令人惊讶的是，灰尘和杂质颗粒对二元部分的贡献相同。这导致了与优化织物质量相关的建议，最终处理应主要侧重于消除较大污染物的视觉影响。原因是较小的颗粒在预处理过程中大多可以被去除，因为它们没有牢固地固定在织物结构中。结果还突出了织物污染与工作场所可吸入灰尘颗粒潜在健康风险之间的联系，强调了在加工过程中进行有效控制的必要性，以保护工人并确保不仅在织造过程中而且在后续过程中的稳定生产。
