Importance of fiber length and maturity in short staple spinning
General - Technology of Short-staple Spinning : "Technology of Short-staple Spinning" deals with the basics, and therefore generally valid, technological relationships in short-staple spinning. The following chapters will be organized according to machines or machine groups. Generally valid basic principles will thus be kept separate from ongoing developments in machine design and construction.
Introduction to Spinning : The annual world fiber consumption in 2004 amounted to approx. 70 mio tons (synthetics: 38 mio tons, cotton: 22 mio tons, cellulose fiber: 2.5 mio tons and others: 7.5 mio tons).While about one third of the man-made fibers is processed as endless filament, still two thirds come in staple fiber form. The larger part of staple fiber, approx. 33 mio tons are processed in short staple spinning. This part of the spinning industry therefore is of great significance in the world of textile production. It is correspondingly important that adequate trained management personnel is available, with the necessary technical and technological knowledge. While technical knowledge relates more to machines, technological aspects are concerned with processing. Technological knowledge is the summarized expression of the basic principles involved in conversion of raw material to semi-finished or fully finished products – separated from the actual or currently realizable possibilities for putting these principles into effect. In relation to spinning, technology is concerned with the study of the production of a yarn. In this context the word “spinning” refers to the conversion of a large quantity of individual unordered fibers of relatively short length into a linear, ordered product of very great length by using suitable machines and devices. In processing natural fibers, the same basic operations are always involved. It is the aim of this volume to provide an introduction to the technology of...
