PROCESSO DE MODIFICACAO DE UM TECIDO PARA MAQUINA DE FABRICAR PAPEL; TECIDO MODIFICADO; E TECIDO PARA FABRICACAO DE PAPEL

摘要

This invention is directed to press fabrics having improved water removal capability. More particularly, this invention is directed to the improvement of the water removal capability of press fabrics by applying hydrophobic and/or hydrophilic coatings. Even more particularly, this invention is directed to a method of modifying a fabric for a papermaking machine which comprises the steps of: (a) applying a hydrophilic or hydrophobic coating to the surface of a fabric to form a layer thereon; (b) drying said coating to form a layer; (c) applying to said dried layer a hydrophobic coating if a hydrophilic coating was used in step (a) or a hydrophilic coating if a hydrophobic coating was used in step (a); (d) drying said coating applied in step (c) to form a second layer; (e) repeating steps (a) to (d) as necessary; and (f) curing the thus modified fabric. a
