A CRITICAL ASSESSMENT OF RECENT PROGRESS IN THE TECHNOLOGY OF COTTON SPINNING

In this paper, a description is given of the machinery developments which, in the post-war years, have led to higher drafts, larger packages and higher machine speeds. The importance of fibre arrangement and sliver regularity is examined, and the effect on subsequent processing in carded and combed qualities and also in sliver-to-yarn spinning is discussed. Comments are made on modern developments in ring spinning whereby higher speeds are attainable. A typical existing post-war installation is compared with a plant which would be recommended at the present time; attention is drawn to the importance of distinguishing between maximum and optimum package size. An outline is given of the possible future trends in machinery development.
