Carded Spinning of Sticky Cotton. Part I: Stickiness Effects on Productivity

Abstract

Ever since cotton stickiness first appeared, spinners have been reporting the disturbances it causes in the spinning process. Despite this, few quantitative studies have evaluated the detrimental effects caused by stickiness. This initial section, Part I, presents the results of an experimental study to evaluate the effects of stickiness on efficiency and breakage in industrial-scale spinning. The relationships between cotton stickiness, breakage, and efficiency are discussed for the card, drawing frame, roving frame, ring spinning frame, and rotor spinning frame. Different methods are used to measure stickiness and select that which most accurately predicts stickiness-induced effects: sugar content determined by HPLC (high performance liquid chromatography), number of sticky points determined by an scr thermodetector, and number and size of sticky points measured by H2SD (high speed stickiness detector). The roving frame is the most sensitive to stickiness and the H2SD appears to be the most accurate predictor of stickiness-induced effects during spinning.
