Comparative study on the quality parameters of ring and rotor spun yarn: A case study

This study presents a comparative analysis of the quality parameters of ring spun and rotor spun yarns, both produced from the same raw material, 100% Brazilian cotton fibers, and prepared into 20 Ne (carded) yarns. The yarns were produced using identical sliver preparation, with drawing before being fed into the ring spinning frame (through simplex) for ring spun yarn and directly into the rotor spinning frame for rotor spun yarn. Key yarn quality properties such as mass variation, imperfections, hairiness, and tensile properties (e.g., count strength product (CSP), breaking force, breaking length, tenacity, work of rupture, and breaking elongation) were compared between the two spinning systems. The findings indicate that ring spun yarn exhibited superior tensile properties including higher CSP, breaking force, and tenacity, while rotor spun yarn demonstrated better uniformity, lower imperfections, and reduced hairiness. The study provides valuable insights into the strengths and limitations of each yarn type and offers recommendations for selecting the appropriate yarn for specific textile applications based on the required properties for fabric performance.
