Abstract (en)
[origin: EP1184511A2] Woven blanket has a woven structure (20) with warps (30) and wefts (40) along and across the running direction of the machine. The fibers are needled to give a felting effect, and at least part of the warps have a twisted structure. The papermaking blanket uses a twisted fiber structure with a circular cross section, using at least three monofilaments. The woven blanket is in at least two overlaid layers, or three layers, with fibers embedded between the upper and lower layers. The warps and wefts of at least one upper layer are bonded with the warps and wefts of at least one lower layer. The twisted filament structure is in a multiple twist or a mixed twist with a monofilament and twisted and/or multiple twisted and/or spun and/or braided multifilaments. The monofilament to give a twisted structure has a diameter of 0.1-0.9 mm, (preferably 0.1-0.5 mm, especially 0.1-0.3 mm). The twisted structure has an average outer diameter of 0.3-1.0 mm, (preferably 0.4-0.8 mm, especially 0.4-0.6 mm). The weft density is ≥ 130 wefts/10 cm, (preferably 130-200 wefts/10 cm, especially 140-180 wefts/10 cm).
