Non-aqueous Wool Fiber Dyeing Process using Reverse Micellar Approach
In textile industry, reactive dyeing using nanoscaled dye carrier in nonaqueous solvent mostly is well dispersibility, low viscosity and high diffusion into wool fabric matrix properties can result in shorter dyeing periods in comparison with the conventional water dyeing process.
The working temperature of nonaqueous dyeing is 88°C, which is 10 degrees lower than in conventional water-dyeing process in terms of energy saving aspect. The obtained color strength in terms of K/S sum value is better than that in conventional aqueous dyeing. Dyeability of wool fibre with reactive dye from the reverse micellar solution was improved without incorporation of textile auxillaries such as electrolytes and chemicals like acetic acid or sodium bicarbonate for pH adjustment.
