REPRESENTATION OF MINIMUM AMOUNT OF BICHROMATE IN WOOL DYEING WITH MORDANT DYESTUFFS

Modified Bentonite with Different Surfactant and Used as a Mordant in Wool Natural Dyeing

Application of Silver Nanoparticles as Metal Mordant and Antibacterial Agent in Wool Natural Dyeing Process

Dyeing of Indian wool with reactive dyes

Wool fibres have been chemically modified by reduction I chlorination under acidic pH Ipre-swelling in conc. formic acid prior to their dyeing with indigenous reactive dyes of different molecular configurations to enhance the reactive dye uptake on wool fibre substrate. The pretreatment processes are inexpensive, less harmful and less time consuming as against the use of imported special wool r...

Lipid Role in Wool Dyeing

The textile industry uses different fibers obtained from various animals, of which the wool from domesticated sheep Ovis aries is commercially the most important. Dyeing is one of the most important finishing procedures of wool processing. It almost invariably involves absorption of water-soluble colorants from aqueous solutions by the fibers. Diffusion is the process by which the colorant mole...

Extraction of Carthamin from Carthamus Tinctorus and Investigating Its Dyeing of Wool Using Potassium DI-Chromate Mordant

Carthamin, the natural dye of carthamus tinctorius (Golrang) was separated by soxhlet extraction and further purified in good yields. Its mordant dyeing of wool, using potassium dichromate as mordant, showed a high washing fastness (above 4). Mordanting by "sweet chrome", "sour chrome", and "reduced chrome" proved that last one to be superior.
