Abstract
Processes used for the wet treatment of fiber were tested for washing cotton to prevent exposure to cotton dust. The processes included a batch process and three continuous processes that used wool scouring equipment, rayon rinse equipment, and shallow bed equipment. Finishes were applied to washed cotton and evaluated in carding and spinning tests. The results of the study suggested that card web neps were always higher in washed cotton than in unwashed cotton independent of the finish. Yarn from washed cotton was generally lower in strength than yarn from the unwashed cotton independent of the finish. The static bar was of considerable help in carding washed cotton at higher rates. The unwashed cotton controls tended to generate negative static readings, whereas the washed samples with finish applied tended to generate positive readings. Finish application and drying were very critical to good processing. Adding potassium salts to the finish bath eliminated the static problems during carding. No finish at any application level returned the washed cotton to its prewashed condition for efficiency of processing or for yarn quality.
