Abstract

The invention discloses a dyeing method for silk fabric and wool fabric by using trichoderma viride spore powder. In particular, the dyeing method comprises the following steps: 1) preparing a culture medium; 2) preparing a spore suspension liquid; 3) preparing a dyeing liquid; 4) dyeing the fabric. According to the dyeing method, uranidin produced by trichoderma viride is utilized for the first time to dye the fabric, and the application range of trichoderma viride is broadened; naturally existing trichoderma viride is utilized to serve as a direct source of dye, and not only has the advantages of being non-toxic, harmless, pollution-free, biodegradable, high in environmental compatibility, and the like, but also overcomes the common problem of relatively poor color fastness of natural dye. The invention further explores an optimal dyeing process of the trichoderma viride spore powder, and the optimal dyeing process has the advantages of being low in equipment requirement, mild in condition, simple and convenient, and the like, and is suitable for large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing and finishing, and relates to a fabric dyeing method, in particular to a green trichoderma spore powder dyeing method for silk fabrics and wool fabrics. Background technique [0002] Natural dyes are derived from animals, plants, minerals and microorganisms with no (or minimal) chemical processing. Compared with synthetic dyes, natural dyes are non-allergic and carcinogenic to the skin, and have better biodegradability and environmental friendliness. As the demand for dyeing textiles with natural dyes gradually increases in the market, the application of microbial dyes in the textile field has also attracted the attention of scholars (see Farzaneh Alihosseini, Kou-San Ju, Jozsef Lango, Biotechnol. Prog. , 2008, 24:742-747 and F.A. Nagia, R.S.R. EL-Mohamedy, Dyes and Pigments , 2007, 75:550-555). At present, the most widely studied and applied microbial pigments are red pigments (such ...
