Abstract

The invention discloses a preparation method of an adsorption type biological enzyme soaping agent for reactive dyes, belonging to the technical field of preparation of printing and dyeing auxiliary agents. The preparation method comprises the following steps of firstly, culturing and fermenting white-rot fungi by using a homemade fermentation medium, centrifuging the prepared fermented liquid to obtain crude enzyme liquid, and then preparing alkaline laccase by taking the crude enzyme liquid as a raw material; preparing a wool keratin solution by taking wool as a raw material, modifying the prepared wool keratin solution, then mixing the modified solution with the alkaline laccase, Tween-80 / liquid paraffin, and the like, and carrying out centrifugal separation; after that, collecting precipitate, and washing the precipitate with acetone and isopropyl alcohol; finally, drying to obtain the adsorption type biological enzyme soaping agent for the reactive dyes. The soaping agent prepared by the method has a better soaping effect and a better anti-staining effect, thus enabling the color fastness to soaping and fastness to rubbing of fabrics subjected to soaping to reach three-level or above; furthermore, the soaping agent provided by the invention does not generate foam in a soaping process, so that the washing times of the fabrics can be reduced, and the energy consumption is greatly reduced.

Description

technical field [0001] The invention discloses a preparation method of an adsorption-type biological enzyme soaping agent for reactive dyes, and belongs to the technical field of preparation of printing and dyeing auxiliaries. Background technique [0002] There are unfixed or hydrolyzed dyes (often called floating colors), size and chemical auxiliaries on the surface of the fabric after dyeing or printing. If these dyes, sizing agents and chemical auxiliaries are not removed, the color fastness and vividness of the fabric will be affected, so the dyed fabric must be soaped, and as a post-processing aid in the printing and dyeing process, soaping Agents play an important role in the soaping process. [0003] In the soaping process, the soaping agent reacts chemically with the dye to wash away the reactive dye that is not firmly combined with the fiber and remove the printing paste, and at the same time prevent the removed dye from sticking to the cloth surface, so as to imp...
