The Accelerating Mechanism of Octyl Hexyl Dimethyl Ammonium Bromide

Abstract:

As a small molecule and cationic accelerating agent, octyl hexyl dimethyl ammonium bromide (OHDMAB) is a very effective accelerator in dyeing silk with reactive dyes. In this paper the accelerant mechanism of OHDMAB was studied. The results showed that OHDMAB can promote the aggregating of dye molecules in aqueous solution efficiently. With the change of the temperature, the concentration of accelerating agent, the aggregation of dye molecules varies to some extent. As a result, the maximum absorption wavelength of dye, the particle size of dye in aqueous solution, and the surface potential are changing regularly. OHDMAB can make the surface voltage of silk positive easily, this maybe the most important factor of the mechanism of the OHDMAB accelerant.
