| Abstract: | Lignin is excellent filler in polyurethane synthetic leather, which gives the special physical properties and processing performance to polyurethane （PU） synthetic leather, and reduces costs. Different lignin screen tailings have a certain impact to the viscosity of lignin/PU blending and the peel strength of PU synthetic leather. The effect of lignin screen tailings on the viscosity and the peel strength of PU synthetic leather were studied. The ideal amount of screen tailings was 5.5%-6.5% （mass fraction） for the lignin/PU blending. |
