WIPO Patent Application WO/2004/074570
Kind Code:
A1
Abstract:
A method of preventing the raveling of the surface of a paper body in a paper making step, particularly in a press part and a dry part, of a paper machine, and a mold releasing agent used for the method and capable of effectively preventing the raveling of the surface of the paper body, the method wherein the mold releasing agent is provided to the member of the paper machine in direct contact with the paper body in the press part and/or the dry part of the paper machine to prevent the raveling of the surface of the paper body when the paper body is separated from that member to lower a surface strength. The method is also applicable to a wire part. Since the suitable mold releasing agent is provided to the member in direct contact with the paper body in the press part and the dry part of the paper machine, the raveling of the surface of the paper body can be prevented to prevent the lowering of the surface strength of the paper body.
