Interpretive Summary: Cotton is the main raw material used in the textile industry. It represents about 40% of the total amount of processed fibers in the world. Cotton can be characterized by a large number of quality parameters and its origin. The basic cotton fiber parameters of length, maturity, strength and elongation, depend on the genectic makeup of the variety, the growing region, i.e., soil and weather/environmental conditions, irrigated or not irrigated conditions, harvesting, and ginning. Saw ginning can cause more fiber damage than roller ginning.

Technical Abstract: The main systems in the world for measuring basic cotton fiber quality parameters are described in this chapter. Definitions, working principles as well as the fiber parameters, which a given system can measure are presented. The measurement systems described in the chapters are, HVI, AFIS, Uster IntelliGin, Quickspinn, IsoTester, Premier Art, ITRU UAK-1, the Cotton Classyfying System and Favimat-Robot by Textechno, the CottonscanTM Instrument and SiroMat by CSIRO, and the Cotton Classifying System of the US Department of Agriculture. Also discussed are forecasted future trends in cotton quality evaluation and methods for calculating so called fiber quality index.
