Problems solved by technology

In the process of producing solid enzyme preparations, a large amount of dust will be produced, which is easily inhaled by the human body, seriously affecting human health and causing great harm to the human body
Moreover, when the solid enzyme preparation produced is used to treat denim garments, it has low catalytic activity, serious re-staining phenomenon, slow blooming, and the added surfactant is not environmentally friendly, etc.

Abstract

The present invention belongs to a biologic enzyme complexes technical field, especially relates to a novel cellulase complexes and a preparation method thereof, including the following raw materials be weight percent: neutral cellulase 5%-30%, ammonium dibasic phosphate: 20%-40%, ammonium dihydrogen phosphate 5%-20%, fatty alcohol polyethenoxy ether 2%-15%, Na2SO4: 25%-50%, cornstarch :2%-15%, color paste: 0.1-0.2%. The invention replaces the traditional ellulase preparation, has a global performance, non dusting, a high catalytic activity, a rapid rocket, a very low back staining phenomenon, and is environmental protection, is used for indigo dye rinsing of bronchobuster clothing with a good rinsing effect, and the prepared bronchobuster clothing has a special reminiscence style.

Description

Technical field: [0001] The invention belongs to the technical field of biological enzyme preparations, in particular to a novel cellulase complex and a preparation method thereof. Background technique: [0002] With the development of biotechnology and the improvement of green textile processing requirements, cellulase has been widely used because it can effectively improve the performance of cellulose fibers and improve the wearability of cellulose fibers. At the same time, cellulase is a biological enzyme. Environmental pollution is small, which is conducive to environmental protection. [0003] But the application effect of pure cellulase is not ideal. When pure cellulase treats textiles alone, the catalytic effect is not significant, and it is greatly affected by pH value and temperature, and is also affected by fuel and additives in the treatment solution. In order to obtain an ideal cellulase preparation, it is necessary to combine a large number of chemical additiv...
