Fabric with pore size gradient. US Patent () describes weft double-knit fabric formed from two different polyester yarns. A micro fibre ( to denier fibres) and a non-micro fibre (two denier fibres) yarn are knitted into an irregular pique knit which is a modification of the basic pique stitch. Woven fabrics are subjected to a combination of in-plane extension/tension, shear, compression, bending in a perpendicular plane and out-of-plane buckling deformations. 10 The tensile properties of woven fabrics depend on the yarn and the fabric structure, that is the yarn twist, yarn strength, weave, crimp and cover. The degree of yarn twist Cited by: 4.

The data also show that, in those instances where a property is texturing-temperature-dependent for more than one feeder yarn, the magnitude of the dependence (i.e., the slope of the property versus texturing temperature curve) is similar for all feeder yarns affected. Therefore, these feeder yarns tend to have equal sensitivity to changes in.
The study has used modified cellulosic yarn Cotton, Tencel, Excel and Modal spun yarns were used as raw material. The weft yarn are used of Tencel, Excel and Modal for all spun yarns was same i.e. 40 S Ne ( Tex) in the weft and cotton 60 S Ne ( Tex) in the warp were chosen for the construction shown in table no. 1.

Yarn properties affecting comfort of the fabric Yarn size: The most common yarns are based on the length of the fibers within them and the appearance and alignment of the fibers, These fibers are either short, long. Spun yarn: made by twisting or bonding staple fibres together to make a.
The quality of hosiery yarn has to be considered with due weight-age to the fluidity of knitted structures and their influence on knit fabrics quality. The crucial yarn properties to be thought-about would be twisted in yarn for shortest doable gauge length, among variation of friction in yarn, yarn irregularity, torsional rigidity and flexural.

JUTE • 2ply • S Twist • Jute is also called "the golden fiber" for . G.K. Tyagi, in Advances in Yarn Spinning Technology, Tensile properties. Breaking strength and elongation are two prime quality attributes of any spun yarn. The strength and elongation of a yarn are important to the processability of the yarn in the downstream processing and operational life of the substrate made with the yarn. An attempt has been made to establish a relationship between morphology and properties of these yarns. High tenacity (HT) polyester yarn has the highest birefringence, amorphous orientation, and long period but is relatively less crystalline. High shrinkage characteristic of HT polyester yarn can be accounted for its higher amorphous orientation.
