Abstract
The invention relates to a method for manufacturing polyurethane leather with an easily dyed surface. The dyed polyurethane leather is obtained by coating easily-dyed polyurethane resin as a synthetic leather surface coating material on the surface of synthetic leather base cloth with a surface finishing technology and then carrying out dyeing treatment. The easily-dyed polyurethane resin contains amino or carboxyl on a molecular chain. Because the easily-dyed polyurethane resin is used as the synthetic leather surface coating material, the dyeing can be carried out by using dye, and the dyed synthetic leather with color effect can be obtained after subjected to the dyeing treatment to ensure that the product has the characteristics of bright color, good coating ventilation, high surface color fastness and small color migration. Compared with the common synthetic leather dyeing, the invention has the advantages of less dye consumption, short dyeing time, capability of dyeing at a lower temperature, simpler dyeing process, lower cost and energy saving.
