Abstract
Surface active agents are obtained by reacting, in water as solvent and under normal pressure, cresol, formaldehyde, sodium sulfite, and 2-hydroxynaphthalene. The surface active agents exhibit excellent high dispersing power upon finely grinding with disperse dyes and in use at high temperatures whereby they are effective in giving level dyeing to polyester fibers in high temperature dyeing processes and give little or no cellulose staining in dyeing a polyester/cellulose blended yarn or fabric by the thermosol process.
