FLUFFY Polyester Yarn

The difference in neps in the Afis with and without top comb; the feeding method of different combers; suitable for the drop of fiber length (Ln of lap) Cotton scale and suitable doffing rate; sliver and roving strength; draw speed; roving roller gauge, etc. Check the company's Loepfe Mill Master ESY version of the alarm yarn chart (see Figure 12). 20 After solving the problems identified by the spring-loaded spring-free spinning one by one, a significant effect was achieved (see Fig..2. And the company will comprehensively promote the quality backtracking management system in other branches. After comparing 96 grains, the histogram comparison of electric yarn clearing defects is shown in Figure 26. Fig.2

. Figure 14 Insufficient FLUFFY Polyester Yarn of the elastic jaws in the front zone checks and rectifies the discovered problems one by one.3 Case 3: Solving the problem of high 140% neps in JC140S yarn Combed cotton 140-inch compact spinning produced by an enterprise, customer feedback 140% of the neps is too high, which affects the quality of the cloth. 17

Fluctuation curve of production efficiency Through analysis of the quality data of electric clearing, it is found that the yarn body is abnormal and there are many coarse details, especially the dense cutting defects at C1, C2, B1 and B2 (see Figure 18). Figure 12: The alarm yarn chart of Loepfe Mill Master ESY version checks the operating status and spinning process of the spinning equipment, and finds that there are mainly two problems: (1) The air supply pressure of the pneumatic cradle is unreasonable,

the standard pressure is 170cN, individual machines The measured pressure of the cradle reached 250cN (see Figure 13), which caused the abnormality of the sliver and neps data. Figure 25 JC140S yarn defect classification chart (after rectification) Through the comparison of data before and after rectification, we can see that after the reorganization of the combing equipment and the optimization and adjustment of the process, all indicators of yarn formation have improved significantly, including 140% of the neps data. Figure 21 Winding efficiency data after rectification 5.
