EFFECT OF COTTON VARIETY AND THEIR FIBER PARAMETERS ON MILL PERFORMANCE AND PRODUCT QUALITY

Patricia Bel, Jacques Hebert, George Ruppenicker, and H.B. Cooper

ABSTRACT

Four varieties of cotton were grown in the same irrigated field in the San Joaquin Valley of California and ginned in the same manner to eliminate variations that environmental, agronomic, and ginning conditions may cause. Mill opening was the same for all cottons, and both single and tandem carding were included on the study. Two of the cottons were Acalas, EA-C30 and EA-C32. The other varieties were a Deltapine (DP-90) and a Stoneville (ST-825). These four varieties gave us a wide range of fiber properties. Yams and fabrics were made from each variety. Ends down tests were also run. Tandem carding was superior to single carding in yam and fabric qualities, except that it caused increased neps as seen in the dyed fabrics. The thicker cell wall caused less neps in the finished fabrics. The Acalas produced the best yams and fabrics with exception of neps for EA-C32. The EA-C30 (with the thicker cell wall) was far superior to the other cottons with respect to fabric neps.
