Abstract

Cotton fabric was treated with aqueous solutions of tetramethylammonium hydroxide (TMAH) and sodium hydroxide of various concentrations. The sorption of both chemicals, the specific weight of the fabric, the cellulose I - cellulose II transition, the BET surface area, the iodine sorption capacity, and the water retention value were measured and compared. Although less TMAH was adsorbed by cellulose than NaOH, the TMAH proved to be a more effective swelling agent for cellulose. The difference between their swelling effect starts to be significant at a concentration of about 2 mol • dm-3.
