Accelerating Mechanism of OHDAB on Silk with Reactive Dye
Abstract:
OHDAB (Octyl Hexyl Dimethyl Ammonium Bromide) is an efficient accelerant for reactive dyes on dyeing silk. The accelerating mechanism of OHDAB was studied in this paper. The results showed that OHDAB could make dye molecules assembled and the particle size of dye aggregate increased with the increase of OHDAB concentration. OHDAB could neutralize the negative charge of silk; even the zeta potential of silk could become positive with the increase of OHDAB concentration.
