Anthocyanins and Betalains – Colours from Wastes: Are They Suitable for Textile Dyeing?

Popis výsledku v původním jazyce

The indisputable advantage of colour agricultural wastes such as moldings, pomace or pulp extracted by pressure from blue grapevine, red beetroot, cherries, berries etc. is their easy seasonal availability, low cost, concentrations in greater volume of material in one place and the relatively high content of coloured substances. These are wastes that often have no other destiny than to be recycled back to the soil as a source of nutrients. Nevertheless, this is quite controversial due to the presence of pesticides, metals and acidic phenol compounds that are not easily processable by soil bacteria. This leads to the gradual acidification, salinisation and growing of soil toxicity and ultimately to lower yields, which need to be tackled chemically again - this is just a vicious cycle with an expanding spiral of ecological consequences. If we consider textile dyeing with waste products containing anthocyanins and betalains, it is necessary to keep in mind what type of agriculture the waste originates from, and then to consider for what purpose these colourful fabrics may serve. The current book is the THIRD in a series of manuscripts under “PROGRESS IN FIBROUS MATERIAL SCIENCE”. These books are collection of chapters dealing with state of the art technologies and the science of polymeric materials in specific.
