ABSTRACT
A study was done on the changes of extra long staple (ELS) cotton fiber properties at the four main stages along the spinning production line. It was found that changes in some properties were significantly related to the initial magnitudes of the properties. Thus, in the opening and blending process, relatively more damage was done to the longer and stronger cotton samples. Also, the carding, combing and drawing processes made relatively more improvement in the shorter and weaker cotton samples.
