| titleOfInvention | Cation dyeing auxiliary of linen reactive dye, preparation method and application of cation dyeing auxiliary |
| abstract | The invention discloses a preparation method of a cation dyeing auxiliary of a linen reactive dye, and application thereof and relates to a preparation method of a dyeing auxiliary of the linen reactive dye, and application of the dyeing auxiliary. According to the cation dyeing auxiliary of the linen reactive dye, the preparation method and the application of the cation dyeing auxiliary, the problems of low dyeing rate and low fixation rate of the conventional linen reactive dye in a dyeing process are solved, and furthermore, the problems that a large amount of dyes retained in a dyeing solution are wasted, the dyeing cost is greatly increased and the environment is polluted because of the use of an accelerating agent NaCl and low dyeing rate and low fixation rate of the dye in a dyeing process are solved. A structural form of the cation dyeing auxiliary of the linen reactive dye is shown in the description. The preparation method comprises the following steps of preparing N-acetylation-degrading chitosan and a hydroxymethyl dimethylamine hydrochloride solution, then mixing and stirring the N-acetylation-degrading chitosan and the hydroxymethyl dimethylamine hydrochloride solution to react, adding methyl iodide and performing suction filtration and extraction to obtain the cation dyeing auxiliary. The cation dyeing auxiliary can be used as an accelerating and fixing agent used in a linen dyeing process. |
