Analyzing the properties of Siro dual core-spun yarns produced with a modified roller for industrial application

Integrating synthetic fibers into yarn manufacturing has revolutionized the development of stretchable fabrics, which have become essential in the textile industry. This research explores the development of Siro-spun dual-core yarns with elastane and PBT (polybutylene terephthalate) as core materials, alongside cotton as the sheath material, using a modified W-grooved roller system. The study aims to evaluate the impact of core material feeding techniques on the properties of the produced yarns. Five different samples were created using several feeding techniques, and their properties were investigated using standard testing methods and statistical tools such as MANOVA. The MOORA (Multi-Objective Optimization by Ratio Analysis) method was also employed to rank the yarn samples based on their overall criteria across multiple quality performances. The results revealed that yarns produced using the modified W-grooved roller exhibited superior mechanical (elongation and strength) and quality properties (hairiness, unevenness, and imperfections) compared to those produced using traditional methods. This comparative study demonstrates the potential of the modified W-grooved roller to optimize yarn performance, offering innovative solutions for stretchable yarn production and meeting the growing demands of the textile market.
