Eco-friendly processing using enzymes has been focused in textile industry in order to reduce environmental pollutions. This paper was suggested to hydrolyze non-cellulose, such as fats and waxes in cotton fabrics by lipase treatment. Enzymatic treatment conditions were controlled according to pH, temperature, enzyme concentration, and treatment time. The physical properties of the lipase-treated cotton fabrics were evaluated by measuring weight loss, moisture regain and dyeing properties. The surface morphology of lipase-treated cotton fabrics were observed by SEM. As a result, the optimum conditions for the lipase treatment were at pH 4.2, temperature 50$^{\circ}C$, concentration 50%, and treatment time 90 minutes. Calcium chloride and Triton X-100 were effective auxiliaries in lipase treatment.
