EFFECT OF THREAD ON YARN QUALITY OFCOTTON/POLYESTER BLEND YARN
Abstract
The strength, unevenness, hairiness of the blended yarn are improved by increasing the ratio of polyester fiber [1-2]. Processes such as carding, cleaning and blending increase the number of neps in cotton yarn [3]. The strength, unevenness, hairiness of the blended yarn depends on the fiber properties, the ratio in the blend, the spindle speed of the spinning machine [4], the yarn count, the high roller pressure and the twist coefficient of the drafting pairs [5-6]. When spinning high quality yarns, the influence of the diameter of the draw rolls, the initial elongation and the twist coefficient imparted to the web on the tensile force in the draw zone has been studied [7-8]. The breakage of the fiber in the thread is determined by the core strength of the fiber and the correct distribution of the fibers along the length of the thread [9].
