Improved Cotton Fiber Quality and Improved Spinning Technology-A Profitable Marriage. Part I. Progress in Rotor Spinning and Progress in the Quality Profile of U.S. Upland Cotton. Part II. The Contributions of Improved Cotton Quality and Those of Rotor

Chris Faerber, Helmut Deussen


Part 1

From the improvements in major fiber properties from 1982 to 1992 a projection is made to further possible progress by 2002. These three fiber profiles are spun into yarns of different counts and the results compared.

Progress in rotor spinning between 1982 and 1992 is described and further likely improvements projected into 2002. The three stages of spinbox development are used to spin the above three cotton fiber quality profiles.

Part II

The spinning results of three fiber profiles on three rotor spinbox stages (= nine conditions) are explained. Spinning performance and yarn quality are related to cost-per-pound figures and profit margins.

The information will isolate the contributions of improved fiber quality on the one hand, and the contributions of spinning technology research on the other. In addition, it is attempted to show the monetary benefit of higher fiber quality levels to the cotton grower by means of a valuation model.
