Embodiment 1

[0047] 1. Natural blue pigment dyes fabrics

[0048] 1. Medium

[0049] Activation medium: 20g soluble starch, 0.5g NaCl, KNO 3 1g, K 2 HPO 4 0.5g, FeSO 4 0.01g, MgSO 4 0.5g, 20g agar, make 1000ml with water, adjust the pH to 7.2~7.4.

[0050] Fermentation medium: 20g soluble starch, 0.5g NaCl, KNO 3 1g, K 2 HPO 4 0.5g, FeSO 4 0.01g, MgSO 4 0.5g, 20g agar, make 1000ml with water, adjust the pH to 7.2~7.4.

[0051] 2. Cultivation of actinomycetes

[0052] Configure the activation medium, pour the plate and test tube after sterilization, take the bacteria stored in the laboratory, streak, place in a constant temperature incubator, activate at 37°C for 4 days to obtain the activated bacteria. The strain adopts natural blue pigment-producing actinomycetes (Jx-blue1), specifically the Streptomyces lividans disclosed in the Chinese patent application with the application publication number CN103602615A (application number 201310562683.5), and the preservation number is CGMCC No.8083, ...

Abstract

The invention discloses an extraction method and dyeing method of natural blue pigment. The method includes the steps of: fermenting blue pigment with a strain to obtain fermentation broth, then extracting blue pigment to obtain blue pigment powder; making the blue pigment powder and water into a dye liquid, heating the dye liquid to 35-45DEG C, putting the fabric in the dye liquid for 10-20min, then adding sodium chloride and maintaining the state for 10-20min, then performing heating to 75-85DEG C from 0.5-5DEG C, adding soda ash, conducting heat preservation at 75-85DEG C for 30-60min, then performing cooling, and carrying out cold water washing and drying, thus finishing fabric dyeing. The blue pigment extracted by the method provided by the invention serves as a natural pigment produced by microbial fermentation, endows pure cotton fabrics with antibacterial properties while dyeing, is bright in color, and has good color fastness to rubbing. The dyeing method provided by the invention is easy to operate and implement, and is easy for industrial production, thus having broad application prospects.

Description

Technical field [0001] The invention relates to the field of natural blue pigment extraction and dyeing, in particular to an extraction method and dyeing method of natural blue pigment. Background technique [0002] In recent years, due to the impact of environmental and energy issues, people tend to pursue sustainable, environmentally friendly and beneficial methods for human health to prepare dyes. The development of natural dyes is the general trend in the development of applied dyes in the world. Natural dyes refer to dyes that are obtained from plants, animals or mineral resources with little or no chemical processing. Many natural dyes are safe and reliable, with natural hue and close to natural substances. Etc. [0003] With economic development and social progress, people’s requirements for a healthy life are gradually increasing, making the use of natural pigments instead of synthetic pigments has become the development trend of the food and cosmetics industries. Therefor...
