Thermal comfort properties of modified yarn path in cotton fabrics

395-401Effect of the modified yarn path in ring spinning on the thermal comfort behavior of the cotton woven fabric has been investigated. The modified ring yarn is produced by changing the path of the yarn in the ring spinning process. The finding shows that it has a clear impact on the fabric geometrical properties and thermal comfort properties when path of the yarn is changed in ring spinning as left and right diagonal path. It is also observed that the air permeability of the fabric decreases with the right diagonal yarn path and thermal resistance of the fabric increases with the right diagonal yarn path. The fabric woven from the left diagonal yarn path shows higher water vapour permeability

Effect of diagonal path on the physical properties of compact and conventional ring yarn

Effect of diagonal path on the physical properties of compact and conventional ring yarns has been investigated. The compact and conventional ring yarns have been spun using three completely different paths in the ring frame, like normal path, right diagonal path and left diagonal path. The yarn spun by the left diagonal path has an additional advantage over the other two paths for both conventional ring yarn and compact yarn in terms of yarn hairiness, yarn evenness, tenacity, elongation and breaking force

Effect of plasma treatment on polyester knitted fabrics: Part II — Moisture management properties

This study focuses on the moisture management properties of plasma-treated polyester knitted fabrics (spun, continuous filament, micro denier and hollow fibre). The effect of different loop lengths and the impact of oxygen plasma treatment on the moisture management properties of the fabric has also been studied. The moisture management properties are better for the plasma-treated fabric and also for the fabric having highest loop length. The moisture management properties of the fabric have been improved with the oxygen plasma treatment.

Effect of Modified Yarn Path on Ring Spinning on the Moisture Management Properties of the Cotton Fabrics

This study discusses the effect of modified yarn path in ring spinning such as straight path, left diagonal path and right diagonal path on moisture management properties of the cotton fabric like wetting time, absorption time, spreading area, spreading speed, accumulative one way transport index and overall moisture management capability. The results show that the fabric made with right diagonal yarn path exhibits better overall performance of the moisture management properties of the cotton fabric

Effect of Modified Yarn Path Ring Spinning on Thermal Comfort Properties of Cotton Fabrics after Plasma Treatment

The influence of air, oxygen and argon plasma treatment on the thermal comfort behavior of cotton woven fabric which is spun from modified yarn path in ring spinning has been investigated in this study. The cotton fabric samples were undergone different plasma treatment namely air, argon and oxygen. The fabric air permeability has tend to be decreased with the plasma treatment and the oxygen plasma-treated fabric has least air permeability. The untreated fabric shows higher air permeability followed by left diagonal yarn path, straight path and right diagonal yarn path. It was also observed thermal resistance and water vapor permeability of the fabric has increased with the plasma treatment and the oxygen plasma-treated fabric has higher thermal resistance and water vapor permeability. The untreated fabric shows lower thermal resistance and water vapor permeability followed by left diagonal yarn path, straight path and right diagonal yarn path

Effect of Weave Parameters on the Tear Strength of Woven Fabrics

The fabric tear strength is an important parameter in textile material, ever since it is close to relate to the service of the fabric. Tear strength of the fabrics depends on the flexibility of the yarn in fabric structure. In this research, the tear strength of 11 cotton woven fabrics is analyzed based on the weave parameters such as crossing over firmness factor (CFF), Floating Yarn Factor (FYF), Fabric Firmness Factor (FFF) and weave factor (P1)

Effect of Modified Yarn Path on Ring Spinning on the Physical Properties of Cotton Fabrics

This study analyses the influence of modified yarn path on ring spinning like straight path, left diagonal path, and right diagonal path on the physical properties of the cotton fabrics like tensile strength, tear strength, and drape performance. The results show that the fabrics made with the left diagonal yarn path gives a better overall performance of the physical properties of the cotton fabrics followed by straight path and right diagonal yarn path

Effect of yarn twist on mechanical properties of glass fibre reinforced composite rods

343-346Effect of twist of glass yarns on the tensile, flexural and interfacial shear properties of composites has been studied. The glass fibre reinforced composite rods have been prepared by hand pultrusion technique with various twist levels. It is found that with the increase in twist level in yarns, the tensile, flexural and interfacial shear strength properties of the composites increase upto 0.25 TPI, 1.0 TPI and 0.75 TPI respectively, followed by decrease in the properties of the composites
