In order to determine the relationship between fiber properties of yarn quality in article, experiments were conducted using a passive method mathematical planning and regression equation was obtained for each optimal parameter. Based on experiments, it found that decrease micronaire, an increase tensile strength, length uniformity, leads specific strength yarn, coefficient variation number bre...

Regarding the importance of ring spinning method among spinning systems, great potentials exist for research about on the improvement of the quality and properties of ring spun yarn. This study aims to improve yarn quality by changing the shape and dimensions of spinning triangle through forming a groove in the middle zone of the front darfting &#10roller with a curvature of 5 to 7 mm. For the ...

Generally, ring spun yarns are manufactured from roving which is produced by frame. In this paper, an experiment has been done producing cotton yarn directly finisher drawn sliver eliminating the Total 3 types of with various linear density 8 Ne, 10 Ne & 12 were using a frame and without next step, physical mechanical properties those including unevenness, imperfections, hairiness tenacity inve...

Yarn quality is judged according to the achieved values of tested yarn properties that are selected in dependence on yarn utilization. Quality level of the yarns can be assessed using the USTER® STATISTICS [2]. This tool is composed of graphs enabling users to compare their measured results of yarn (sliver, roving, fiber) with the corresponding worldwide established fibrous product quality refe...

In this paper, the theory of the ballooning yarn has been adapted to the loop spinning process. The aim of a numerical simulation of high-speed winding process consists in establishing the shape of the curve of rotating yarn in the section between the gripping line of drafting motion rollers and the place where the yarn is wound upon a tube, and in determining the tensile force in the yarn in t...
