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...

abstract in this research we have considered the effect of using natural pigment like (beta vulgaris) and (rubia tinctorum) and compound of these two pigments on white angel fish (pterophyllum scalare).. this consideration on 76 white angel fish with average weight of 1.12±0.5gr in 5 treatments including 5 and 10gr madder in kg food, 5 and 10gr red beet per kg food and combined treatment(5gr ma...

This study aims to extend color shade range of Rubia tinctorum L. (Dyer’s madder) natural dye on wool textiles via binary combination Al, Sn, Cr, Fe, Cu, Ni, Co, Zn mordants. Wool yarns were premordanted, dyed with 75.0%owf madder dye, and characterized for their strength, colorimetric parameters, fastness. Nature single metal cations substantially affected shades, fastness properties due diffe...
