Heat Induced Changes in Cotton Fiber and Spun Yarns

Donald E. Brushwood


 
ABSTRACT

Heat is often applied to seed cotton in gins to enhance removal of foreign matter by lowering the lint moisture content. The drying process can be detrimental to fiber properties if the drying temperature is too high or if the fiber moisture content gets too low. Recent research has shown that drying temperatures and times well within the ranges used in some modern gins produce undesirable changes in cotton fibers and yarns. Raw cotton fiber tenacity and length properties decreased and short fibers increased as temperature and heating time increased. Yarn uniformity was adversely affected by heating especially at high temperatures.
