Industrial fabric with silicone-coated surface suitable for use in papermaking machines

摘要

An industrial fabric comprising a base substrate and a coating of silicone resin adhered only to raised surfaces or in discrete discontinuous locations so to increase the sheet guiding and sheet restraint capacity of said fabric whilst maintaining desired fabric air permeability is disclosed. These industrial fabrics have an improved sheet restraint and wear resistance along with acceptable permeability. The improvement is effected by coating only the high spots of the fabric with silicone material. The coating methods used in this invention may include kiss roll coating, gravure roll coating, rotogravure printing, rotary screen coating, screen-printing and/or flexography. The improvement is also applicable to corrugator fabrics.
