Interpretive Summary: THE OVERALL AIM OF THIS ARTICLE WAS TO SUMMARIZE THE PROPERTIES OF COTTON TRASH AT EIGHT CLEANING POINTS ON A CARD WITHIN A MULTI-BALE LAYDOWN. THE USDA COTTON QUALITY RESEARCH STATION OFTEN COLLABORATES WITH LOCAL TEXTILE INDUSTRIES TO UNRAVEL THE PROCESSING PROBLEMS. TESTING METHODS AND IMPROVEMENTS IN CURRENT TRASH MEASUREMENT TECHNIQUES ARE EXPECTED TO 1.) TO BETTER UNDERSTAND AND IMPROVE CARDING, 2.) TO INCREASE PROCESSING EFFICIENCY, AND 3.)TO ASSESS THE IMPACT OF COTTON TRASH ON CARDING.

Technical Abstract: TRASH REMOVAL IS REQUIRED DURING PROCESSING FOR IMPROVED TEXTILE-PROCESSING EFFICIENCY. COTTON TRASH HAS OFTEN BEEN A LEADING CAUSE OF ENDS-DOWN DURING SPINNING. TRASH ARISES FROM VARIOUS PLANT SOURCES AND FIELD CONTAMINATION. TO COMBAT TRASH AND EFFICIENCY PROBLEMS TEXTILE MILLS OFTEN SPECIFY COTTON BALES, WHICH THEY ACQUIRE, SHOULD HAVE A LEAF CLASSIFICATION NO HIGHER THAN 3 FOR PROCESSING ON THEIR AIRJET OR VORTEX SPINNING SYSTEMS. IN PROCESSING, THE CARD IS AN EXCELLENT LOCATION TO OPTIMIZE COTTON CLEANING DUE TO THIN WEBS OF COTTON FIBERS. THIS STUDY INVOLVED A MILL RUNNING A 40 BALE LAYDOWN FROM WHICH SAMPLES WERE TAKEN AT EIGHT SEPARATE CLEANING POINTS ON A CARD ON THE SAME CLEANING LINE RUNNING A (50/50) COTTON/POLYESTER BLEND. THIS RESEARCH EVALUATED SEVERAL MEASUREMENT TECHNIQUES TO CHARACTERIZE TRASH PARTICLES AT NUMEROUS CLEANING POINTS ON FIVE DIFFERENT MODERN CARDS. THIS STUDY COMPARED THE TYPE, SIZE, AND DISTRIBUTION OF PARTICLES AT EIGHT CLEANING POINTS. FURTHER WORK IS NEEDED TO DETERMINE THE EFFECT OF COTTON TRASH REMOVAL AT THESE EIGHT CLEANING POINTS ON HIGH SPEED TEXTILE SPINNING.
