Processing sticky cotton: Implications of trehalulose in residue build-up

Research output: Contribution to specialist publicationArticle

Abstract

Cotton stickiness, caused by excess sugars on the lint from the plant or insects, is a very serious problem for cotton growers, cotton ginners and yarn spinners. During processing sticky cottons contaminate machinery in varying degrees. Causes of stickiness are explained and the incidence of trehalulose. Several authorities are quoted on the relationship of stickiness caused by honeydew and humidity levels. The testing procedure used 12 contaminated commercial bales and five non-sticky bales, and the testing equipment and methods are listed. Spinning trials in both ring and rotor spinning are conducted on 17 mixes of sticky and non-sticky cotton with further details supplied. Analysis of sugar content in spinning dust employed the Elitex BD200M rotor spinning machine dust accumulations from 20 rotors after a four-hour run. Water adsorption is discussed. The Differential Scanning Calorimetry (DSC) technique is examined and DSC profiles recorded. Trehalulose content has the tendency to increase in the residues collected on the equipment while the other sugars have not.
