Currently, synthetic dyes are widely used to colour textile materials. However, safer and more sustainable bio-based alternatives currently being explored. In this context, by-products wastes from agricultural value chains have been investigated as potential sources of natural dyes. Nutshell promising because they abundant, contain interesting dye molecules such quinones easier handle their low...

Dyeing properties of different fabric species were investigated using leaf extract Juglans regia L. For this purpose, the cotton and wool fabrics dyed brown napthaquinon colorant extracted from walnut leaves by pre-mordanting, meta-mordanting post-mordanting methods in presence copper sulfate (CuSO4.5H2O), ferrous (FeSO4.7H2O) alum (AIK(SO4)2.12H2O) at medium pH. Color codes determined with Pan...

Reducing pollution in various industries such as textile is very important. In this paper, two parallel methods were used to reduce of the process and application dye. The first approach was selection plant-based dyes (Madder with botanical name Rubia tinctorum Reseda odorata) a tannin-based mordant (pomegranate peel Punica granatum). second extraction dyeing ultrasound media. efficiency madder...
