At least two layers of MD threads (32, 33, 43, 44, 48, 50) are provided which are stacked one over the other in pairs and form product contact MD threads (32, 43, 50) and non-product contact MD threads (33, 44, 48). At least the material of each product contact MD thread (32, 43, 50) facing the product side (PS) forms a contact angle, measured according to the Wilhelmy plate method, of at least 80°, preferably at least 90°, more preferably at least 100°. In order to prevent the adhesion of threads to the fabric (30, 40, 45) and in order to reduce the air permeability, the fabric has a single layer of CMD threads (31, 41, 42, 52), and the cross-section of each product contact MD thread (32, 43, 50) has at least two regions, a first region of which is formed of the first material and a second region of which is formed of the second material. A substantial proportion, preferably a predominant proportion, of a tensile force acting on each product contact MD thread (32, 43, 50) can be transmitted from the second region, and the cross-section of the product contact MD threads (32, 43, 50) have a second region in the form of a core (61) and a first region in the form of a casing (62) which surrounds the core (61). The product MD threads (32, 43, 50) are preferably coextruded or are extruded in two successive steps. The MD threads (32, 33, 43, 44, 48, 50) have a flattened cross-section, preferably a rectangular cross-section, wherein a ratio of a height of the cross-section to a width of the cross-section preferably ranges from 1:1.2 to 1:10, preferably from 1:1.5 to 1:4. The invention further relates to a method for producing a nonwoven and to the use of an industrial fabric (30, 40, 45).
