| titleOfInvention | Preparation method of complex leather dye |
| abstract | The invention provides a preparation method of complex leather dye, belonging to the technical field of leather dye. The preparation method solves the problem that the solubility of the leather dye declines due to a salting-out effect of anhydrous sodium sulphate when existing leather dye is commercialized, and the problems, such as uneven dye and low dye-uptake, frequently arise when leather is dyed. The preparation method of the complex leather dye comprises the following steps of: a, mixing the original dye with water, and fully stirring to dissolve the mixture to form a dye water solution; b, adding a commercialized adjuvant into the dye water solution obtained in the step a to perform a reaction; c, dry at a preserved temperature to obtain the complex leather dye. According to the preparation method provided by the invention, the complex leather dye has the advantages of excellent solubility, high affinity to leather, excellent leveling property, high dye-uptake and the like during dyeing, so that the complex leather dye is very suitable for leather dyeing. |
