Abstract

The invention relates to an orange lyocell fabric prepared by dyeing a monascus fermentation extract and a preparation method of the orange lyocell fabric. The preparation method comprises the following steps of fermenting monascus, culturing and purifying to obtain monascus orange pigment; and preparing a phenol oxidase solution and a cellulase solution, preparing a dyeing solution from the monascus orange pigment, the phenol oxidase solution, the cellulase solution, a H2O2 solution and the like, putting manganese dioxide, a lyocell fabric and the dyeing solution into a dyeing machine for dyeing, carrying out enzyme deactivation on the dyed lyocell fabric, washing with tap water, and drying to obtain the orange lyocell fabric. According to the invention, cellulose and the monascus orange pigment are respectively activated by selecting cellulase and polyphenol oxidase, so that a graft polymerization reaction of the cellulose and the monascus orange pigment is realized. The dyeing conditions are mild, and the pollution to the environment is small; and the dyed orange lyocell fabric has a relatively high K / S value, and the soaping fastness and the dry rubbing fastness are relatively high in grade.

Description

technical field [0001] The invention belongs to the technical field of fabric preparation, and in particular relates to an orange lyocell fabric dyed by fermented monascus fungus extract and a preparation method thereof. Background technique [0002] Natural pigments are food pigments obtained from natural resources; pigments mainly extracted from animal and plant tissues and microorganisms (cultivation), of which vegetable colorants account for the majority. Natural pigments derived from roots, stems, leaves, flowers, fruits, animals, microorganisms, etc. of natural plants, in terms of the amount added, the proportion of food coloring in food is very small. The development and application of natural pigments has become a topic of general concern to scientific and technological workers in various industries. People try to obtain natural pigments from various animal and plant resources, and at the same time explore their physiological activities to alleviate and solve variou...
