Abstract - In the complex landscape of yarn manufacturing,
handling and raw material cost saving- there has been a lot of works on this sector. But still there is a lot of opportunities to make the best use of machinery settings such as roller settings, this type of research focuses on how the settings of the rollers in a spinning machine can influence the properties and quality of the yarn produced.
the roller gauge setting of a ring frame machine emerges as an important determinant influencing the quality and attributes of the final yarn product. This research explores the complex relationship between the roller gauge setting and Yarn properties, namely Imperfection Index (IPI), Uniformity, Hairiness, Count Strength Product (CSP), and Coefficient of Variation in mass (CVm%). Thus, the study measures how the changes in roller gauge of ring spun yarn machine affects the quality of end yarn. Understanding the effects of roller gauge settings is vital for optimizing the ring spinning process in textile manufacturing. The research employs a systematic approach, conducting experiments with varying roller gauge settings on a ring frame. The study unfolds through a systematic exploration of three distinct yarn counts-20 Ne, 26 Ne, and 40 Ne-under the wider and closer roller gauge setting. Employing modern testing methodologies, the study relied on the High Volume Instrument (HVI), Automated Fibre Information System (AFIS) and Evenness Tester to meticulously analyze and quantify the quality during the process and final yarn properties. The experimental results offer in depth insights into the complex relationship between roller gauge settings and yarn quality, presenting a comprehensive understanding of the dynamics at play. This research contributes substantively to the optimization of yarn manufacturing processes by providing empirical evidence on the direct influence of roller gauge settings on critical yarn attributes.
Begum et al. [1] explores the relationship- between card cylinder speed and roller gauge settings during the breaker drawing stage and its consequential impact on the evenness and imperfections of combed yarn. The methodology, key findings, and implications of this research offer valuable insights into the initial stages of yarn formation. Cui et al. [2] reports a systematic study on the SDS (Soft Drafting System), a modified drafting system based on the ring spinning frame, aimed at enhancing yarn quality. The research, divided into two parts, compared the SDS with the conventional drafting system for spinning different yarn types and explored the impact of key process parameters using Response Surface Methodology. The study revealed significant improvements in yarn evenness and a reduction in imperfections, with statistically significant parameters, but without notable interactions, and it identified optimal conditions for achieving high-quality yarn production. Hossain et al. [3] utilizing Uster testing to evaluate yarn quality before the knitting and weaving processes can effectively mitigate problems associated with defective fabric production and suboptimal dyeing, leading to reduced production hurdles and a decreased likelihood of customer rejection. An experiment examining 40Ne, 50Ne, and 60Ne ring-spun yarns, which consisted of a 35% cotton and 65% polyester blend and were produced through the same fiber and sliver blending process, demonstrated that increasing yarn fineness corresponded to higher unevenness and coefficient of mass variation. Conversely, yarn hairiness decreased with the finer yarn types following a sequence of 40Ne > 50Ne > 60Ne.
