Abstract:

Based on the recent researches of microorganisms pigments in dyeing and finishing, the different properties and formations of water/lipid-soluble pigments, two methods of dyeing were introduced. The study and development status of fungus and bacteria (Chromobacterium violaceum, Vibrio, Aspergillus. etc.) which have been or might be used in dyeing were discussed, including the cultivate progress, fermentation condition, dyeing process and the properties of the dyed fabrics. Results indicated that microorganisms pigments were widely used due to their better biodegradability, well-developed cultivation technology and higher yield. The fabrics could obtain great color and some main color fastness could satisfy the requirement of wearability. Some fabrics were endowed with antibacterial properties. However, as natural pigments, some problems of microorganisms pigments such as light fastness, color spectrum also needed to be solved.

Key words: fungi, bacteria, microorganism pigments, natural pigments, dyeing, fermentation
