Spinning Performance and Yarn Properties of Cotton-Polyester Blends

Abstract

Cottons from the California, Memphis, New Mexico, and West Texas growth areas were blended with polyester staple to determine the effects of different cottons on the spinning performance and yarn quality of several blend levels. Combed 60's and carded 20's yarns were produced. For the combed study 65% cotton 35% polyester, 50% cotton—50% poly cster, and 35% cotton—65% polyester blends were processed. For the carded phase 100% cotton, 75% cotton—25% polyester, and 50% cotton—50% polyester blends were processed. The New Mexico cotton produced the best results in the combed phase. The California cotton produced better results than the Memphis cotton except for the 35% cotton— 65% polyester blend. A 1-in. West Texas cotton, a 29/32-in. West Texas cotton, a 1.50-in. polyester staple, and a 1.25-in. polyester staple were used i the carded study. The longer cotton produced the better results. The number of ends down decreased with the increased presence and length of the polyester staple. The longer polyester produced a superior yarn quality for the 50% cotton 50% polyester blend, but not for the 75% cotton 25% polyester blend.
