Effect of Winding Tension Parameters and Rewinding Passages at Winding on Cotton Yarn Properties

In present study, the trials were undertaken on winding machine to study the effect of winding tension process variables on yarn properties. The winding tension was varied at 3 levels and five yarn counts were selected: two medium counts (30s and 36s) and three coarse counts (20’s, 24’s, and 26’s). In all, 15 trials were conducted. The yarn samples were assessed for important yarn properties, such as imperfections, classimat faults, RKm and hairiness, Elongation, IPI, Package density and optimizing tension parameters of individual count for obtaining quality yarn.

Introduction
Yarn tension control is a vital parameter for quality and efficiency in textile processes. It determines the build and structure of the package, and it has a significant influence on productivity of various processes such as winding, twisting and cabling, and in subsequent processes such as weaving and knitting [1]. However, a great majority of yarns are tensioned by primitive means (textile parameters), resulting in loss of production and inferior quality. The ideal solution for most processes is the ability to set the yarn tension to a desired level and to be assured that it does not change over time at any yarn position. However, this ideal is rarely achieved. In Most cases, it almost becomes a game of trying to find out how much tension variations a process can tolerate and then adjusting the process speed accordingly. With precise tension control, many processes can run at least 30% faster and have the added benefit of quality improvement at the same time [2][3][4][5][6].

Material and Method
In order to study effect of the winding tension variations on yarn count at winding machine and the effect of number of winding passages on yarn parameter, Five different yarn counts were selected on winding machine [5][6][7][8][9].

Results and Discussion
From Figure 1 it can be observed that the overall yarn quality in terms of imperfections, and hairiness were not improved significantly with lower breaks at winding. The yarns (20's) made from 100% cotton showed particular trend, improvement found in RKm, Elongation, total IPI value. It has been observed that at 650cn tension level RKm, elongation, winding cuts founds to be improved. This is due to the better control on winding tensions. From the results, it can be inferred that the improvement is more distinct at winding tension 650cn which gives improvement in yarn properties of 20's count.
From Figure 2 it is clear that at, rewinding the overall yarn quality in terms of imperfections, and hairiness not improved significantly with lower breaks at winding. The yarns (20's) made from 100% cotton shows particular trend, at rewinding and improvement found in, Elongation, total IPI value. It has been observed that tension level elongation was at 650cn, with an improvement in winding cuts significantly. This is due to the better yarn control on rewinding tensions. From the results, it can be inferred that, the improvement is more distinct in at rewinding tension 650cn, which gives improvement in yarn properties of 20's count. By this the total cuts /100 km found to be decreased at rewinding when compared to winding.

Conclusion
Reference to Figures 1-6, Present investigations summarized that, As increase the tension level at winding machine on 20 S , 24 S , 26 S , 30 S , 36 S count RKm, Elongation not improved significantly but Total IPI value and winding cuts found improved significantly. For coarser and medium finer count, among the three tension levels, lower tension contribute towards optimum Rkm value and improvement in winding cuts.
At Rewinding for all the counts, number winding cuts were reduced, because in winding all the objectionable fault were removed in previous winding passage and As decreases the tension level at winding machine for all five counts the unevenness, RKm, elongation were not improved significantly but total IPI and winding cuts/100km reduced at lower tension levels at rewinding stage.
