The Interaction between Reactive Dye and Octyl Trimethyl Ammonium Chloride
Abstract:
Octyl trimethyl ammonium chloride (OTMAC) is a very efficient accelerant for reactive dyes on dyeing silk. In order to understand the accelerating mechanism, the interaction between dye molecules and OTMAC molecule was studied in this paper. The results showed that the DTMAC made the dye molecules assembled and the particle size of dye assemblages could reach to more than 500nm. The assembling of dye molecules leads to increase of the maximum absorption wavelength of dye. The higher the temperature is, the weaker the interaction between dye molecule and accelerant.
