New Technique to Produce a Cotton/Polyester Blend Yarn with Improved Strength

This paper describes a newly developed, relatively simple but effective technique of producing a novel pseudo-composite cotton-rich staple blend yarn with improved tensile properties. The spacing between cotton and polyester rovings drafted simultaneously on a ring-spinning frame affects yarn structure, resulting in significantly stronger yarns than those produced by drafting the same two rovings together. The new composite or combination yarns may be useful in developing relatively stronger cotton-rich materials suitable for a variety of finishes and end uses.
