摘要： The invention describes a new synthetic fiber material of polyhydroxyether, as well as a melt-spinning method for its production. The new material can be used, in particular, for stabilization of the reinforcement fibers of high-performance fiber composite materials before they are embedded in the matrix material. During this usage, the polyhydroxyether fiber material dissolves at a temperature above its glass transition temperature entirely in the matrix material, so that the reinforcement fibers can be arranged largely free of kinking. In addition, it forms cross-links with the matrix material to form a homogeneous matrix and thus does not constitute a disruptive third phase in the composite material. The compatibility of the matrix and reinforcement fiber is also improved. It was possible to improve the bending strength of test slabs by 12% as compared to that of reference slabs with polyester filament.

摘要： 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.
