A kind of preparation method of dyeing-free superfine fiber synthetic leather base with high color fastness |
| abstract |
The invention relates to a method for preparing a dye-free superfine fiber synthetic leather base with high color fastness. The preparation method comprises the steps of reducing the weight of the base cloth, impregnating the colored water-based polyurethane, coagulating the polyurethane, post-processing and the like. The prepared superfine fiber synthetic leather bass has full color and high color fastness, and no further dyeing is required. In the preparation process, the amount of dye used is small, the utilization rate of the dye is high, organic solvents such as toluene and dimethylformamide are not used, and the preparation method is an environment-friendly superfine fiber synthetic leather bass. |
