Natural dyes based on plants and mushroom for textiles

Use of natural compounds for textile dyeing

It’s a solution that soon will revolutionize the countrywide textile industry. CeNTI, in partnership with four other entities, has developed a new color palette for textile products based on natural dyes extracted from plants and mushrooms.

With this new, more ecological and sustainable color range, it will be possible not only to reduce the use of synthetic and auxiliaries’ dyeing textiles, but also, and mostly, to ensure the environmental and economic sustainability of this process.

The innovation factor

It is the result of a research that involved not only Tintex, the textile company that led the consortium, but also Ervital and Bioinvitro, companies specialized in plants and mushrooms, which provided the most promising species for further extraction of natural color.

The application of natural dyes in textiles and the color fastness tests were the areas assumed by CeNTI and CITEVE. For this purpose, were used eco-efficient processes with easy industrial implementation. Textiles dyed with natural compounds have shown good color fastness after exposure to sunlight and washing.

With this innovative and technically advanced solution, it will be possible for textile companies to respond to today's challenges, styles and consumption patterns, focused in healthier and eco-friendly products.

PICASSo, the name given to this research Project, will also allow companies to comply with current European legislation, which determines the use of more sustainable and harmless alternative compounds, on detriment of synthetic dyes, widely used in the sector.

Another one of the main advantages associated with the use of natural compounds in textile dyeing processes, and which the research has proven to be related to their intrinsic antimicrobial properties, is that are effectively transferred to textiles, which activity is proven after several cycles of washing.
