“…The evenness of the yarn is assessed using quality metrics such unevenness (U%), coefficient of variation of mass (CVm%), thick place, thin place, neps, and hairiness [ 20 ]. Unevenness is a unit of weight or irregularity variation per unit length.…”

In recent years, the spinning or yarn manufacturing sector has seen remarkable technological advancements, emphasizing high-quality yarn production, especially for cotton combed ring spun yarns. In the case of better quality ring spun combed yarn, each part of the ring frame is significant. To fulfil this issue, this study focuses on understanding the impact of the drafting roller hardness on cotton-combed ring-spun yarn quality. It delves into how ten top and bottom roller hardness combinations influence yarn quality parameters. The cotton combed yarns underwent rigorous testing after spinning on ring frames with varying drafting roller hardness. Key quality parameters studied included yarn Imperfection Index (IPI), Unevenness (Ue%), Hairiness (Hi), Elongation at break (Eb%), and Count Strength Product (CSP), and Tenacity (Te). The primary insight was that extreme roller hardness adversely affects all parameters except Elongation at the break value obtained for the shore hardness value of 80/83. Yarns produced using medium-hardness rollers showcased fewer imperfections due to more consistent fibre flow and minimized drafting slippages, resulting in an even twist. These findings are pivotal for the yarn manufacturing industry, hinting at potential refinements in production methods. The usage of the Fuzzy DEMATEL (Decision-Making Trial and Evaluation Laboratory) methodology also determined that Te CSP) and IPI values significantly influence the combed yarn quality when adjusting roller hardness, whereas Hi is the least influential. Therefore, this study offers twofold insights: determining the optimal roller hardness and identifying the most affected quality parameters.

“…Another reason for that might be that a larger spacer size increases the chance of exerting more even drafting, causing more fault-free yarn. Moreover, larger spacer size increases the number of thick and thin places and neps because of the smooth gripping of fibres and uniform drafting [59]. However, overly increasing it negatively affects the fibre's movement, which may lead to uncontrolled movements [58].…”

Spinning represents the foundational step in textile manufacturing, with yarn quality significantly influencing subsequent processes. Consequently, enhancing yarn quality remains a primary concern for spinners. Of various spinning techniques, ring spinning stands out for its blend of productivity and quality. The final ring yarn is produced by the ring frame, a machine encompassing multiple functional zones. A pivotal component within this frame is the spacer between the top and bottom aprons in the drafting zone. It modulates drafting pressure and fibre movement, directly affecting yarn quality. This research explored the impact of spacer size on yarn quality by employing seven distinct spacer sizes to produce 20 Ne cotton combed yarn. Results indicated that smaller spacer sizes often yielded inferior yarn quality. As the size increased, quality improved; however, after reaching an optimal size, further enlargement led to a decline in five key quality metrics: CVm (%), IPI, Hairiness, Tenacity, and Elongation %. This fluctuation can be attributed to changes in fibre movement and drafting pressure in the drafting zone. The study employed Interpretive Structural Modelling (ISM), a methodology grounded in expert opinions, to rank these quality parameters in importance. Through ISM calculations, yarn tenacity emerged as the most crucial quality parameter, aligning with its significance in producing woven fabrics. Furthermore, a Cronbach's Alpha score of 0.66 underscores the robust internal consistency and interrelation attesting to the study's reliability.
