A detailed study of the quality and quantity of fine dust and trash removed from cotton fibers by the SRRC Tuft-to-Yarn system in its various stages of processing is presented. Collection of fine dust and trash was accomplished by isokinetic sampling from the respective pneumatic systems of the mini-condensers and OE spinners. An impaction-type precutter permitted classifying dust particles from the sampled air into two fractions, one greater than 15 μm aerodynamic diameter and the other less. Three grades of cotton, SM, SLM, and SGO, were used in the study which also included a determination of the cleaning efficiency of each of the processing stages, based on trash content and amounts removed as measured by the Shirley analyzer. A comparison is made between the proportion of fine dust removed by the system and the residues of dust/trash found in conventional OE spinner rotors.
