The expediency of using Everlase in desorption of protein contaminants from cotton-polyester fabrics was established. The optimum treatment conditions were established (pH of the medium, temperature, incubation time) in which Everlase manifests the maximum catalytic activity. The physicochemical mechanism of action of Everlase in removing protein stains from the surface of fabrics was revealed. The effect of adding SF and inorganic salts to the solution containing Everlase enzyme was studied, and it was found that adding them increases the quality of removal of protein stains from the surface of the fabrics. Addition of 0.7% ASF, 0.5% Na(5)P(3)O(10) and CaCl(2) is most effective. An effective product for removing spots of protein origin while increasing the quality of dry cleaning of clothing and improving the environmental safety of the process and economy of resources was developed based on the experimental data.
