Factors influencing the enzymatic desizing of woven cotton and polyester/cotton fabric have been examined using a medium‐temperature‐stable enzyme or one with high thermal stability. The effect of variation in time, temperature and concentration on degree of desizing, fabric absorbency before bleaching, whiteness and degree of desizing after bleaching were assessed by regression analysis on the results of statistically designed experiments. The dominant factors were temperature and time, while variation in concentration often had no significant effect. The results show that more than brief treatment with a high‐temperature enzyme has a negative influence on final whiteness. The polyester/cotton fabric, sized with a mixture of starch and poly(vinyl alcohol), was poorly desized by the medium‐temperature enzyme, but after bleaching desizing was adequate. Improved correlations for absorbency were obtained using a logarithmic absorbency index.
