Definitions

  • a fTORA/E Vs MACHINE FELT COMPRISING WOVEN FABRIC HAVING FIBROUS BATT NEEDLED THERETO BACKGROUND OF THE INVENTION This invention relates to paper machine felts comprising a base fabric having batts needled to one or both sides.
  • the machine felt may be used in the paper, cellulose and asbestos-cement industries.
  • Needled felts for the paper, cellulose and asbestoscement industries are presently manufactured by necdling one or more fibrous batts to a woven base fabric.
  • the base fabric consists of spun threads made of wool 'and/or synthetic staple fibres or multifilaments.
  • width shrinkage may amount to 35 percent.
  • One consequence of this width shrinkage is that the base fabric and therewith the entire machine felt becomes denser and more compact.
  • the service life of a machine felt in the pressing zone of a paper machine is normally limited by the gradual decrease in its permeability due to clogging. This reduction in permeability gives so called crushing of the paper web during its passage through the press nip and results in a replacement of the machine felt.
  • Base fabric yarns made from wool and/or synthetic staple fibres or multifilaments may treated with a resin, thus achieving a stiffening or reinforcing effect.
  • this process does not yield expected advantages, since the stiffness or rigidity substantially disappears during needling and subsequent processing.
  • the present invention aims to reduce to a minimum the above-discussed defects by providing machine felts having a base fabric with transverse yarns entirely or partially of plastic monofilaments having a thickness of preferably 0.2 0.6 mm.
  • this invention provides a machine felt comprising a base fabric having a batt needled to one or both of its sides, the base fabric having longitudinal yarns spun of wool and/or synthetic staple fibres or multifilaments and transverse yarns made entirely or partially of plastic monofilaments. Because the monofilaments are not compressed in the longitudinal direction and the needled-on batt prevents the monofilamerits from forming curved elements or eyelets, machine felts can be manufactured without substantial width shrinkage. For purposes of comparison, the total width shrinkage calculated from the differance between the original width of the base fabric and the final felt width, is, when using normal base fabrics, approximately 35 percent and, when using base fabrics according to the present invention only approximately 10 percent.
  • FIG. 1 is a perspective view of a portion ofa machine felt according to the invention during manufacture
  • FIG. 2 is a cross-section through the said machine felt at a later stage of its manufacture
  • FIG. 3 is a perspective view of a portion of one type of a base fabric.
  • the machine felt shown in FIG. 1 consists of a base fabric 1 having longitudinal yarns 2 (with respect to machine direction of the machine felt) and transverse yarns 3.
  • the yarns 2 are made from spun filaments of wool and/or staple fibres or multifilaments, and the yarns 3 consist entirely or partially of monofilaments.
  • the base fabric 1 has been shown exposed on the lefthand side of FIG. 1 to clearly show the relative positions of yarns 2 and 3.
  • the batt 4 on one side has been partially needled down onto the base fabric and, at the right-hand portion, the batt has been completely needled to the base fabric.
  • a batt 5 is attached to the opposite side of the base fabric.
  • the fibres of this batt 5 are caused, in the same manner, to penetrate partially into and through the base fabric 1 and the already attached batt 4.
  • the yarns 3 may be polyamide monofilaments having 8-10 filaments per cm. and a yarn diameter of for example 0.3 mm.
  • the monofilaments may vary in thickness from 0.2 mm to 0.6 mm.
  • the base fabric is composed of longitudinal yarns 2 and transverse yarns 3.
  • the yarns 3 consist of cores of monofilaments 3 around which are wound yarns 3". These yarns 3" may be spun of wool and/or synthetic staple fibres or multifilaments.
  • a shape-retaining machine felt which undergoes reduced width-shrinkage during its manufacture, for use in dewatering presses and other operations in which water penetrates the felt and is carried away, comprismg:
