Abstract

Cotton is a cool, soft, comfortable and is the principal clothing fiber of the world. Cloths made of this fiber absorb and release perspiration quickly, thus allowing the cloth to “breath.” The advantages of polyester over cotton fibers are its strength, brightness, easy-care, low price, consistency in quality and availability. But it has low moisture regain (0.4%) as compared to cotton (8%). There is no perfect fiber that contains all the qualities of cotton and polyester mentioned above. In this context, blending is the technique to combine fibers which emphasizes the good qualities and minimizes poor qualities of the fibers. In blends of polyester/cotton, the fibers provide crease recovery, dimensional stability, tensile strength, abrasion resistance, moisture absorption, drape ability, etc. Different blend ratios of P/C have been considered for experiment, i.e., 100% cotton, CVC (60% cotton, 40% polyester) and PC (50% cotton and 50% polyester). In this work, we studied the yarn characteristics with several P/C blend ratios of 30/s Ne. Here, the properties of blended ring spun yarns are compared with the same of 100% cotton yarn and the results are discussed in terms of the following quality parameters: Mass irregularity (CV% and U%), Thick, Thin & Naps (IPI: Imperfection Index), CSP, single yarn strength and Hairiness.
