Determining Stickiness in Cotton using Contest-S Instrument

Stickiness is a serious global problem. Stickiness contaminated cotton can impede ginning, spinning and all subsequences textile processes. Contest-S is a thermo-detector method determining stickiness, mainly for raw cotton and for sliver if needed. In this study; 18 cotton samples were originated from different textile factories. All cotton samples classified using Contest-S for stickiness grade into very low, low, moderate, high and extremely very high spinning risk probability stickiness for all studied samples. Sample of E/018 had the highest stickiness grade and showed very high spinning risk probability (283.67). Meanwhile both of Egyptian cotton Giza 95 and Giza 98 had not risk probability, hence stickiness grade mean results were 16 and 24, respectively compared to the other rest 16 cotton samples which varied from no, low, medium, high and very high spinning risk probability. In general; well-implemented integrated for both of pest insecticides and all agricultural practical plant management plans are the main defenses against stickiness problem.
