This project work aimed to investigate the interactive effects of carded roving parameters (i.e., roving hank and twist) and break draft of ring frame on the quality of compact yarn such as evenness, strength and hairiness. However, in this work, compact spun yarns produced from carded roving hanks of 0.70Ne and 0.90Ne while the roving twist per meter inserted at two levels (i.e., 40 and 45) for each of hank. Moreover, the break draft values of ring frame kept at three levels (i.e., 1.15, 1.25 and 1.35) for each type of roving. However, 100% cotton compact yarns of 24Ne and 32Ne produced for this experimental investigation. However, results showed that yarn unevenness (U%) and imperfection index (IPI) values of compact yarn decreased for the finer roving hank (0.90Ne) irrespective of yarn fineness. It was also noticed that low twisted roving improved yarn evenness during coarser yarn (i.e., 24Ne) production. Regarding the count strength product (CSP) value, increasing levels of roving twist deteriorated the CSP results in general. Trend of CSP results also revealed that finer roving produced higher levels of CSP results for comparatively finer yarn production. As far as yarn hairiness is concerned, it was observed that finer roving (0.90Ne) having higher levels of twist reduced yarn hairiness irrespective of yarn fineness without any exception. Finally, it can be said that this study will help the researchers for comprehending the influences of the process parameters during the production of compact yarn from carded roving.
