“…After that, we will provide our arguments based on our conclusions obtained. The size of the spacers in a ring-spinning machine directly impacts the amount of drafting pressure used on the fibres, affecting the fibre drafting zone in the double apron drafting system [19]. The drafting pressure could be increased using more extended spacer sizes, resulting in a firmer grip on the fibres and, https://doi.org/10.31881/TLR.2023.102 presumably, more uniform drafting [22].…”

“…Table 9 shows that with the increase of the spacer size up to 4, the value of the total hairiness reduces, but the oversize of the spacer increases the value of hairiness. For the larger size of the spacer, fibres are smoothly controlled at the drafting zone, which causes the condensation of the protruding short fibres to the main yarn body, causing less amount of hairiness [19]. Another problem with the smaller spacer size is that it increases the chance of fibre entanglement, causing more fibre loops, protruding fibres, and hairiness [62].…”

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.

The forces exerted on fibres during drafting in the drafting zone with the upper and bottom aprons of the Ring Frame significantly impact the yarn quality. Aprons are crucial in manipulating fibres by facilitating movement and directing them toward the primary drafting area. From these two aprons, the bottom apron's tension is changed by changing tension spring bar groove hole positions. There is no scope for changing such settings in the case of top aprons. This research aims to achieve high-quality cotton carded knit yarn by selecting an appropriate bottom apron tension due to the significant role in proper drafting and twist insertion at the time of the manufacturing process directly affecting produced yarn's strength, evenness, imperfections, and hairiness properties. To fulfil this requirement, six yarn samples are produced each time by using 5 different tensions of the bottom drafting aprons. The samples underwent quality parameter testing, including Unevenness (U)%, Coefficient of Variation (CV)%, Imperfection Index (IPI), Hairiness (H), and Count Strength Product (CSP). The findings indicated that increasing the tension of the bottom apron while maintaining positions 1, 2, and 3 reduces the occurrence of neps, variations in thickness and thinness, and imperfections. In contrast, CSP is increased due to elevated stress on the fibres. In general, maintaining an appropriate tension enhanced the quality of the yarn, and the best quality was obtained for position 3, considering all the quality variables. Moreover, by using Interpretive Structural Modelling (ISM) methodology, the pairwise relationship between the quality variables is shown. Finally, after calculation, those quality variables are arranged in three levels. According to this level, the quality parameters are ranked where the top is the highest. It is observed that Count Strength Product is at the highest level, which indicates that CSP should be given more priority. Moreover, the end use of this yarn is to produce knit items, and for the knitting yarn, CSP is one of the most influential quality variables.
