ARTICLE ANNOTATION

quote
This article analyzes the quality indicators of cotton fiber and their direct impact on the spinning process in yarn production. In particular, it highlights the practical significance of using the modern HVI (High Volume Instrument) system to assess fiber quality and the Spinning Consistency Index (SCI). SCI is a comprehensive indicator that includes key physical and color characteristics such as micronaire, fiber length, strength, uniformity, reflectance (Rd), and yellowness (+b). The article demonstrates the role of the SCI value in forming fiber lots and in daily production planning. Analytical results are presented based on fiber batches prepared for CCM 30, KCD 30, and OE 30 yarn types. For each yarn type, the quality of the fiber lots based on SCI and the physical-mechanical properties of the produced yarns, including the IPI (Index of Imperfections), were analyzed. The results show that yarns produced from fibers with a high SCI value exhibit better overall quality characteristics.
