ABSTRACT:
Papermaking felt containing a hydrophilic urethane resin that can maintain functions such as water drainage, wet-paper smoothness, and wet-paper transportability by imparting a hydrophilic property to the papermaking felt thereby preventing the deposition and accumulation of adhesive contaminants without impairing the compression recoverability of the felt thus sustaining its antifouling capability.
