Title:
製紙機械用プレスフェルト、および前記フェルトの製造方法ならびに製造装置
Document Type and Number:
Japanese Patent JP4939399
Kind Code:
B2
Abstract:
The invention relates to a press felt for use in the press section of a paper machine. Said felt comprises a nonwoven layer lying on one of its surfaces, the surface of said layer being connected and fixed to the felt by a thermoplastic binding material. According to the invention, the surface of the nonwoven layer is smoothed by the application of pressure from a smooth surface during the cooling of said layer surface from a temperature in excess of the melting temperature of the thermoplastic binding material to a temperature below the melting temperature. To manufacture the press felt, an untreated press felt, which contains the nonwoven layer and the thermoplastic binding agent is first produced, the thermoplastic binding agent being distributed in the nonwoven layer in the form of thermoplastic adhesive fibres and/or a thermoplastic adhesive component of bicomponent fibres. The desired press felt is produced from the untreated press felt by means of the aformentioned temperature and pressure treatment using a smooth surface, thus enabling the press felt to be simultaneously thermofixed.
