Abstract
In a press fabric for a pulp machine having a multilayer structure, which fabric is woven using, as a warp, a monofilament as a warp and, as wefts, a yarn obtained by bundling raw yarns of a small diameter and forming a fine water sucking space therebetween and a monofilament, at least an upper surface side weft and a lower surface side weft are arranged vertically as the wefts; the yarns forming a fine water-sucking space and monofilament are used as wefts constituting the lower side layer; they are arranged at a ratio of 2:2 or 1:2; and two monofilaments are arranged adjacent to each other as the lower surface side wefts, whereby the press fabric can maintain its dewatering channel for discharging water to the back surface side from the initial stage to the final stage of use.
Claims8
A press fabric for a pulp machine having a multilayer structure obtained by weaving warps, each of which is selected from a group consisting of a monofilament, monofilament twisted yarn and a twisted yarn having a monofilament as a core, with as wefts, yarns obtained by bundling raw yarns of a small diameter and forming a fine water-sucking space therebetween and monofilaments,
- wherein at least upper surface side wefts and lower surface side wefts are arranged vertically as the wefts;
- one of the weft yarns forming a fine water-sucking space or two of the weft yarns forming a fine water-sucking space which are adjacent to each other, and two of the monofilaments which are adjacent to each other, are alternatively arranged as the lower surface side wefts.
