Dyeing Accelerant Octyl Hexyl Dimethyl Ammonium Bromide on Silk with Reactive dyes

摘要

In order to increase the fixation rate of reactive dye on silk, and decrease the dosage of accelerant, Octyl hexyl dimethyl ammonium bromide was synthesized and used as an new accelerant for reactive dyes to dye silk. The results showed that only little Octyl hexyl dimethyl ammonium bromide as accelerant, the dye up-take rates and fixation rates of reactive dyes was very high. The dosage of Octyl hexyl dimethyl ammonium bromide was 10 times less than sodium sulfate. And the color fastness of dyed silk was very high. The dyed silk with Octyl hexyl dimethyl ammonium bromide as accelerant could be cleanly washed by anion surfactant. These showed Octyl hexyl dimethyl ammonium bromide had promising application prospect.
