Abstract
Cationic dye is a special dye for acrylics, but it is very difficult in dyeing through the core. In practice, the price of a special leveling agent for acrylic fiber is high, and uniform staining is poor. By mixing a number of organic solvents in the dye bath, we can improve the structure of fibers and their deep-dyeing. We used n-propanol, isopropanol and benzyl alcohol as organic solvents, by adjusting the pH value and the appropriate temperature, and with special depth and leveling agent for dyeing soaping fastness contrast, to find economically viable process conditions.
