The use of the high speed stickiness detector on a large range of cotton coming from different countries

For some years now, all those involved in the cotton industry, from grower to spinner, have become increasingly concerned by the stickiness encountered during cotton-to-yarn processing, and have attempted to find a remedy. It was at the beginning of the 1980s that certain spinners noted that the spinning process was substantially disrupted by sticky cottons. This stickiness can be caused by physiological sugars produced by the plant or by entomological sugars produced by insects. Numerous detection methods have been developed to measure stickiness and reduce is effects. The CIRAD technology laoratory has developed two thermomechanical methods for this detection: the SCT thermodetector and the high-speed H2SD. Both systems are presented here and have been used to measure cottons from various origins.
