| 摘要 |
<p>This invention consists of a method to produce a composite wet-press papermakers felt by which one side of a textile base fabric can be given a uniform, smooth coating of polymeric resin particles fused together to provide a porous, elastic surface. Its distinguishing feature is the application to the textile base fabric of a homogeneous foam, composed of resin particles, a binder material, and a solvent, in a uniformly thick coating. The textile base fabric is then subjected to heat, which evaporates the solvent and fuses the resin particles to each other and to the fabric base.</p> |
