Seed cotton was harvested both wet and dry from the same field and subjected to different drying treatments. The goal was to determine the quality effect of using high drying temperatures on both wet (18% moisture) and dry (6% moisture) cotton fiber. As was expected, high drying temperatures on already dry cotton damaged fiber length and strength but resulted in better trash removal during cleaning. However, high temperatures correctly used did not damage the length and strength of wet cotton fiber when compared to an already dry control that received no drying. The effects of drying damage carried into spinning, with the overdried fiber producing weaker and less uniform yarn.
