Benefits of Compact Ring Spun Yarn in Other Spun Yarns

BACKGROUND In 1991, textile researchers at Universities in Eastern Europe introduced a change in the traditional manufacture of ring-spun yarn. Condensation of the roving web prior to entering the spinning triangle produced a less hairy…

Warp Sizing – An Industry Problem!

BACKGROUND Formaldehyde modified resins were introduced to the apparel market in the 1950’s. These finishes imparted a no-wrinkle character to cotton fabric and promised relief from the tedious job of ironing apparel. Preliminary marketing…

Improving Warp Yarn at the Size Box

Physical properties of warp yarn are improved by incorporating oligomer resin into the yarn interior at the size box. These improvements yield benefits at each step of the fabric formation process from size box to the woven greige fabric.…

A New Perspective to Improve Warp Sizing

Higher quality yarn improves the weaving process. Introduction of very small non-film forming resin particles in conventional size formulations modify and provide improved fiber cohesion in the warp yarn bundle. This transient effect…

Nanotechnology Benefits in Fabric Formation

Nanometer (Nm) resins have been shown to modify fiber behavior in existing textile yarn. Incorporation of nanometer (Nm) resins in conventional warp size formulations improve weaving performance, improve fabric quality and reduce cost.
