초록

This study has examined the removal of mixed soil of protein and fat by protease. Cotton and PET fabrics were soiled by spotting of hemoglobin and triolein, respectively. The soiling order and soil concentration were changed in this procedure. The soiled fabrics were aged at 130℃ for 20 minutes. Protease was added in the alcohol ethoxylate(AE) detergent solution. The removal effciency was evaluated by analysis of protein and/or fat on the fabrics before and after washing, respectively. The detergency of PET fabrics was higher than that of cotton fabrics. The removal efficiency of hemoglobin was improved by protease from cotton and PET fabrics. Especially the removal efficiency of hemoglobin was remarkably improved from cotton fabrics. With the increase of hemoglobin and triolein (1:1) mixed soil, the removal of mixed soil was increased in proportion to mixed soil content up to a certain point. but it began to decrease above the point from cotton fabrics, while it was generally increased from PET fabrics. The detergency of total mixed soil from cotton fabrics was higher in case of soiling order with triolein after hemoglobin than in case of soiling order with triolein before hemoglobin. But the soiling order was not greatly effected in the detergency of total mixed soil from PET fabrics.
