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. Unfortunately, even today it is very difficult to precisely identify producer countries affected by this problem as stickiness is governed by several factors which induce annual and spatial variations that modify its intensity. Also, no official system is yet available to classify this criterion. Furthermore, as this phenomenon has already produced marked economic effects, information concerning the origins of contaminated cottons it not always made available.
