Definitions

  • the present invention relates to composite sheeting, and more especially to fabrics suitable for use in the manufacture of printers' blankets and to blankets incorporating such fabrics.
  • Conventional offset printing blankets are composite materials composed of layers of woven fabric and rubber, presenting a smooth rubberised surface to receive the ink to be transferred.
  • the woven fabric is usually composed of combed cotton in warp and weft, but may have high modulus spun rayon in either warp or weft.
  • the main requirements for such a fabric are that it should have a high modulus in the warp direction (to prevent stretching of the blanket on the printing machine), be smooth and without slubs or knots, be stable under vulcanizing conditions (when this is utilized) and afford adequate adhesion to the rubber layers.
  • the blanket should also be sufficiently flexible to pass round rollers in the printing machine, and afford adequate cushioning for printing.
  • the present invention seeks to provide a novel smooth-surfaced fabric of improved properties and an improved printers' blanket incorporating the fabric.
  • the fabric according to the invention comprises a rigid warp knitted base fabric composed of relatively fine yarns of continuous man-made filaments, closely spaced and relatively coarse inlaid warp yarns and relatively coarse weft insertion yarns, the inlaid and insertion yarns being also composed of man-made fibres and extending through the knitted structure without interlacing with one another, one face of the fabric being substantially constituted by the inlaid warp yarns.
  • the fabric according to the invention has several advantages over the conventional fabric, because, apart from the basic knitted structure of fine yarn, the relatively coarse load-carrying warp and weft yarns do not interlace and lie completely flat, and there is no crimp in the warp and weft such as is imposed by a woven structure of similar strength. In consequence, the fabric has a higher modulus than a woven structure.
  • Preferred fabrics employ continuous filament yarns for both the inlaid warp and inserted weft. Moreover, for use in printers' blankets, it is preferred that the inserted weft yarns should be bulked or textured, and preferably also closely spaced.
  • the preferred yarns for the warp knitted base fabric are 33 dtex 6F polyester filament yarns. These fine yarns, preferably having a count in the range 33-110 dtex, contribute little to the load-carrying properties of the fabric or to the surface, but confer two-dimensional rigidity on the inlaid and inserted, but not interlaced, structure of the warp and weft.
  • the preferred inlaid warp yarns are 550 dtex 96F polyester. These yarns are relatively coarse, for example in the range 110 - 1100 dtex but are smooth and untextured.
  • the inlaid warp yarns are disposed in pairs, with only one wale of the knitted base between each pair. Being closely spaced in the fabric, and held rigidly in position by the knitted base, the inlaid warps provide a substantially continuous, smooth surface on one face of the fabric
  • the weft insertion yarns are preferably textured or bulked yarns, more especially having a count in the range 120 - 1220 dtex.
  • suitable yarns are air-textured nylon or polyester yarns, which may be analogous to 'Tsslanized' yarns although much heavier than the yarns usually textured by that process.
  • Alternative yarns suitable for this purpose are torque-textured polyester yarns.
  • the bulked or textured weft yarns afford the desired cushioning and also offer a greater adhesion key to the layer of rubber or other elastomer in the manufacture of printers' blankets.
  • the fabric is prepared as necessary to receive one or more elastomeric coatings and is then coated and, if appropriate, vulcanized, for which purposes conventional techniques may be employed.
  • the blanket may include more than one layer of fabric, of which not all need be fabrics according to this invention. However, in any layer of fabric according to this invention the warp face should be directed towards the face of the blanket.
  • the fabric After being knitted, the fabric may be stretched in the warp direction and heat set in this condition to adjust the modulus as desired, followed by calendering to assist in closing gaps in the fabric structure and to increase the smoothness of the fabric surface.
  • a key coat for example an isocyanate coat
  • is to be applied to enhance adhesion between the fabric and the elastomeric layer this is conveniently coated after the calendering operation.
  • a rubber-receptive yarn may be used, for example in the warp, with a resorcinol/formal- dehyde latex adhesive dip treatment or other adhesive system known in the art.
  • the elastomers that may be used in conjunction with the fabric of this invention in the fabrication of printers' blankets include:
  • Printers' blankets according to the invention are thinner and lighter than conventional blankets of comparable strength without any sacrifice of performance. They are also cheaper. Because of their reduced thickness, they are able to pass round smaller rollers without buckling at the inside surface and are therefore more adaptable in their application.
  • A is the warp knitting yarn
  • B and C are the smooth, untextured warp inlay yarns
  • D is the bulked or textured weft insertion yarn.
  • the preferred yarn parameters are identified above.
  • the threading of the machine is as follows:
  • the fabric structure described is outstandingly well adapted for use in composite sheeting such as printers' blankets, the structure is believed to be novel in its own right and,with the substitution of yarns of different characteristics (for example extensible yarns), can be used to provide smooth-faced fabrics for a variety of different end uses.
