    摘要: V-ribbed belts are formed by thermoplastic shaping and contain ribs that run at least on a first side in a longitudinal direction of the V-ribbed belt. The first side contains a layer composed of a textile warp-knit fabric made up of two different yarns. The warp-knit fabric is constructed from a first yarn composed of filaments with a module of more than 5N/1000 dtex, and a second yarn composed of filaments with a module of less than 2 cN/1000 dtex, both based on 5% extension. The first and second yarns form a coherent network and the yarns do not twine around one another. V-ribbed belts can be formed using an elastic warp-knit fabric, whose extension is based on the construction of the knitted fabrics. The belts maintain better noise reduction both in the new state and after a relatively long service life.

    摘要: A flexurally elastic drive belt (1) has a cover layer (2), a reinforcement layer (3) formed of individual cords (4) and a substructure (5). The substructure can include ribs (6) and grooves (7). The drive belt is further provided with a textile overlay on the working side (8) thereof that is susceptible to wear. The textile overlay (10; section B of FIG. 1) of the drive belt (1) combines a very durable resistance to wear and a noise attenuation especially for wet noises. This is achieved in that the overlay has, in a state in advance of fabrication and vulcanization, an elongation at tear of at least 30% in the longitudinal direction and of at least 100% in the transverse direction and is made of a textile material including staple fibers in a proportion in terms of quantity of at least 30% by weight.
