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. Warp sizing technology has been in a period of stagnation following the introduction of synthetic polymers into size formulations nearly 60 years ago. As noted in the following “Warp Sizing: A Brief History”, abrasion-resistant surface barriers may have reached optimum performance in sizing.
