Prioritizing the quality parameters of cotton carded knit yarn by varying tensions of the bottom aprons of the ring frame

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