this is a report on a major segment of a long-range, highly complex study of the textile manufacturing process in relation to producers of raw cotton, to individuals and groups who handle and modify cotton at various points in its marketing sequence, and to consumers of finished cotton products. the objective of the long-range task is to construct a system of mathematical relationships (a model) which can provide guidance to the various groups working with cotton--from those engaged in the development of new varieties to the manufacturers of consumer goods. this guidance would provide estimates of relative use values of different qualities of raw cotton when each is available in a given supply, processed in an optimum manner, and utilized where it can make its maximum contribution to satisfy consumer demand. the unique approach to studying textile manufacturing in the broad sense, the methodology employed, and the basic data developed are considered important to the industry at this time
