Dyeing of natural Rhubarb dyes on cationised cotton fabric
The natural vegetable dyes have the characteristics of non-toxicity, harmlessness and non-pollution. Natural cellulose fiber fabrics dyed with natural vegetable dyes not only have more added value but also have realized natural clothing. This is a good research on ecological and green textiles with the requirements of textile green consumerism of people in the new century. The quaternary ammonium salt cationic reagent which is stable, small, single has been synthesized successfully in laboratory. The ion property of cotton fibers is turned from negative group to positive group by the modification of this reagent. The dyeing performance of cationised cotton fabrics dyed with natural Rhubarb dyes has been improved a lot as compared with the original cotton fabrics. The dry and wet rubbing fastness and washing fastness are good. Binding states of cationised cotton fabrics with Rhubarb dyes have been studied in this paper, So we can infer that the mechanism of Rhubarb dyes on cationised cotton fabrics is belongs to the mechanism of electric absorption, which is according to the characteristic equation curve of Langmiur.
