Abstract:

In order to achieve environmental pollution dyeing, microbial pigments used as textile dyestuff were summarized based on recent researches at home and abroad. The sources of microorganisms, pigment properties, especially dyeing properties and effects were introduced according to three primary colors (red, yellow and blue). The results showed that microbial pigments could dye textiles with relatively good effects, and some main color fastness could satisfy the requirement of wearability. However, poor sunlight fastness had become a burning problem. This paper pointed out that more work should be done on the culture medium’s deflationary force, high efficiency of pigment extraction and screening of high quality strains.

Key words: microbial pigment, textile, dyeing, natural dye
