Dyeing of woollen and polyamide fabrics by beetroot waste from cannery

Popis výsledku v původním jazyce

This work deals with the textile dyeing use of coloured waste that arises in the canneries during the processing of beetroot. The conditions for the optimal extraction of beetroot dyes (betalains) were investigated. Treated and untreated by mordant alumwoollen and polyamide fabrics were dyed with extract in various acidic environments. It was found that the yellow betaxanthins and red betacyanins show a different affinity for these textile materials, which resulted in an entirely different colouring ofboth fabrics and this it is discussed. This effect can be used e.g. for streaked blended fabrics or colour patterning of binary knitted fabrics. The dyed fabrics were also tested for light fastness, wash fastness and health safety (pH and metal contentin the leachates from the fabrics) in accordance with Decree No. 84/2001 Coll., concerning requirements for clothing and products for children.
