Optimum Drafting Conditions Of Polyester And Viscose Blend Yarns

Comfort aspects of finished polyester-cotton and polyester-viscose ring and MJS yarn fabrics

The influence of different experimental conditions on the thermal comfort behavior of polyester-viscose and polyester-cotton ring and MJS yarn fabrics has been studied. The results show that the yarn structure and the fibre cross-sectional shape have a large influence on improving the thermal comfort of woven fabrics. The fabrics made from MJS yarns perform better than those of the ring yarn fa...

Effects of Changes in Front Drafting Rollers Geometry on the Properties of Ring Spun Yarns

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 roller with a curvature of 5 to 7 mm. For the to...

solvent texturing of polyester yarns using trichloroacetic acid/methylene chloride

the effects of trichloroacetic acid/methylene chloride (tcac/mc) on the mechanical properties and solvent texturing of polyester yarns are studied. the treatments are carried out in unstrained and strained states at different concentrations of tcac for various treatment times. breaking load and elongation-at-break of treated yarns have been recorded. treatments of polyester yarns with tcac/mc i...
