ACACIA ARABICA (BROWN)
Vachellia nilotica (commonly known as gum arabic tree, babul, thorn mimosa, Egyptian acacia or thorny acacia) is a tree in the family Fabaceae. It is native to Africa, the Middle East and the Indian subcontinent. It is widely distributed throughout arid and semi-arid zones of the world. Acacia arabica has been proved as effective medicine in treatment of malaria; sore throat (aerial part) and toothache (bark) 3-8 have tested the anti-fertility activity of A. arabica pods and nuts. The methanolic extracts of A. arabica pods have been claimed against HIV-PR.
An average 15-year-old plantation yields about 12.5 tons of bark. About 22,000 tons of babool barks are produced annually valued at Rs 55 million. The bark of babul tree contains tannin and gallic acid and therefore, tree is planted for its bark. It has great medicinal value with antioxidant activity. The bark of Acacia has been traditionally used to produce gum Arabic. Although this is mainly used as a thickener and stabilizer in the food industry, it is also a fast dye on cotton. It is extracted from the dry powdered bark in alkaline solution and produces a range of shades from brown to grey, depending on the metal mordant used.
We employ the Arabica bark powder to produce beautiful light to dark brown and grey shades on cotton, wool, silk and all natural textile substrates by standardized dyeing process using different combination of natural mordants on fibers, fabric and garments with excellent fastness properties.
