Agro-waste and easily renewable plants as sources for natural silk dyes

In this paper, the possibility of using wastes and readily renewable vegetable raw materials as a source of natural dyes for silk is examined. The following plants were used: camomile flowers, onion skins, walnut and ash bark. Considering they are dyes from the group of mordant dyes, potassium aluminium sulphate dodecahydrate, copper(II) sulphate pentahydrate, iron(II) sulphate heptahydrate are used as mordant. Silk was chosen as the material because of the tradition in Croatia and the attempt to revitalize cultivation. Results of this research are presented through the analysis of CIELAB colour values based on spectrophotometric measurement. The final colour map was used to colouring silk scarves inspired by circles in grain. Bio-wastes have the attention of researchers as a source of natural textile dyes due to their ecological background, abundance and availability at minimal costs.
