520 $a The project is conducted with an aim to probe the possibility of producing low torque ring weaving yarns for industrial application by a torque reduction device attached on the conventional ring machine.
520 $a A study is conducted on the geometry of ring spinning triangle and its effect on the yarn torque. A modified energy approach is presented to study the distribution of fiber tension in the spinning triangle under the applied of yarn spinning tension. The shape of spinning triangle is represented by a shape parameter newly introduced in the analysis. The simulated results indicate that the distribution of fiber tension is influenced obviously by the shape of spinning triangle.
520 $a A system for investigation of the fiber configuration in staple yarns has been developed in this study. The main feature of the system is that it can capture and store consecutive images of single tracer fiber, thus the image acquisition becomes faster and more accurate. The investigation of yarn structures demonstrated that low torque ring yarn possesses ring like appearance, compact structure, wrapper fibers, some parts of fibers arranging in opposite direction to the yarn twist and higher rate of fiber migration.
520 $a Statistic models have been developed for the relationship between yarn properties and spinning parameters with the help of Fractional Factorial Methodology and Response Surface Methodology. The optimum spinning parameters are found, based on the developed models.
520 $a The properties of low torque ring yarn and the resultant fabric are comprehensively investigated. The test and analysis exhibit some exciting results of low torque ring yarn with great reduction of yarn snarling and yarn hairiness. The results also demonstrate that low torque ring yarn fabric exhibits improved denim fabric and twill fabric appearance, a fuller, thicker and more smooth hand.
520 $a The investigation of the effect of yarn torque on the surface smoothness of denim fabric was conducted theoretically and experimentally. The experimental study demonstrates that the appearance of the denim fabrics has been greatly improved by using the low torque ring yarns as weft yarns.
