It would be desirable to improve the dimensional stability of drying screens for a drying section of a paper machine. This invention relates to porous paper machine clothing (1, 11, 21) for dewatering a paper web in a paper ma-chine, comprising a filament lay-up made of at least one layer (2, 12, 22) of longitudinal filaments (3, 13, 23) and at least one layer (4, 14, 24) of transverse fila-ments (5, 6, 7; 15; 25) which cross the longitudinal filaments (3, 13, 23), wherein the longitudinal and transverse filaments (3, 13, 23; 5, 6, 7; 15; 25) are single-component filaments, which is characterised in that the longitudinal and transverse filaments (3, 13, 23; 5, 6, 7; 15; 25) are fused at crossing points (8, 16, 27) to each other and/or to parts (17, 18, 19) joining them as a result of heating to the melting temperature which is restricted to said crossing points (8, 16, 27). The invention further relates to a, method of producing porous paper machine clothing such as this.
