Effect of Strand spacing of SIRO Compact yarn on fabric properties

Textile Technology

Over the past 25 years the traditional twisting or folding operation has undergone considerable change and development. One technique still employing the ring spindle is that of stage twisting. This method is unusual in that, unlike many other developments, the main object has been to improve yarn quality rather than the more common aim of reducing costs.However, ordinarily the standards must be first spun and then two folded involves additional process cost. Therefore, the spinners have long demanded spinning and twisting in a single operation. The “SIRO SPINNING TECHNOLOGY” process offers the solution. In this project work an attempt is made to study the effect of strand spacing of SIRO yarn produced by using compact spinning system. Yarn was produced by 5 different strand spacing length with two different suction pressures. Various properties of these yarns were studied. The trials have been conducted by optimizing the distance between the two roving strands & varying the negative pressure applied in the suction zone. Finally the results has been optimized to find the in what parameter the Quality results of the eli twist yarn will perform better. In the second part based on the optimized results of yarn, the fabric has been produced with different combination and the properties of fabric have been studied. Based on the results obtained the best combination of yarn parameter has been found. For optimization of results the statistical tools and regression analysis were used
