In this month, the production management personnel of our enterprise have a comprehensive understanding of the quality requirements of downstream customers for yarn, and do quality management work from the perspective of downstream customers to achieve twice the effect with half the effort. This is a brief analysis of the ten common quality problems of downstream customers complaining about spinning mills.

1 High warping breakage rate

2 Holes in the cloth

There are many problems with warping breakage, and it is necessary to focus on improving the strength of the yarn, reducing the uneven strength, and eliminating the poor forming and twisting of the package; Control of the coarse and thin defects of the cloth: long and coarse, long and thin, to focus on pre-spinning; short and coarse, short and thin, to focus on after-spinning; Do not overly pursue the CVm as the goal, the yarn evenness and quality consistency should be good; Yarn transportation causes wear, it is necessary to do a good job in protection and responsibility assessment to reduce unnecessary quality complaints; The removal of foreign fibers must use foreign fiber removal machines and electrical removal functions, and do a good job of anti-foreign fiber management.

When spinning enterprises encounter downstream customer complaints about quality problems, do not just talk about things, should do inferences, dig deep into the deep-seated causes of customer feedback quality problems, and take customer complaints as an opportunity for quality improvement, because customer complaints provide us with a clearer quality management direction and goals.
