Abstract: The influence of mercerization under different conditions on the tensile properties of cottons bas been investigated and the conditions for imparting maximum strength have been identified. In general, mercerization in two stages rather than one (30 % followed by 10 % caustic soda solution) has been found to give the most satisfactory results. The extent of improvement in bundle strength for different cottons ranged from 49 to 104 % for fibres and from 15 to 43 % for yarns. The breaking elongation was, however, reduced by 24-63 % for fibres and by 46-63 % for yarns. Fibres and yarns which were suitably mercerized and dried after cross linking possessed a strength almost equal to that of the unresinated samples. The development of a machine for continuous mercerization of single yarn on the basis of these observations bas been attempted.
