Moderate Moisture Storage Effects on Strength, Color, Stickiness, and Carbohydrate Content of Raw Cotton

Donald E. Brushwood


Honeydew contaminated cottons were specially treated to reduce sticki-ness. Sticky cottons were stored at moisture levels of 10 and 14.5 percent for 1, 5, 10, and 20 days at room temperature. Reducing sugars, thermodetector stickiness, and individual sugar contents, as determined by High Performance Liquid Chromatography (HPLC) were conducted to determine effectiveness of these treatments. Fiber quality measurements in the form of fiber strength and colorimeter reflectance and yellowness were also determined for each treatment. Minor reductions in stickiness were achieved at 14.5% moisture levels and longer storage times. However, fiber strength, yellowness, and reflectance was adversely affected. The 10 percent treatment up to 20 days had no effect on cotton stickiness, strength or color.
