초록

Cotton fabric was deed with a reactive dye in water/dichloromethane two-phase immiscible solvent media. In order to minimize dye loss due to its hydrolysis, the reactive dyeing was carried out in dichloromethane containing a small amount of water. With only 2ml of water in 23m1 of dichloromethane, 1.0g of cotton fabric could be dyed perfectly. The uptake ratio was increased greatly, compared with that of normal reactive dyeing in a waters medium. It would seem that the one of hydrophobic solvents, dichloromethane, can assist the eden dyeing as it disperses a small amount of dye-dissolved water phase and conveys this water phase to the fabric entirely and uniformly.
