Here are the key properties of KGS metallized fabrics in some more detail:

  • Excellent dimensional stability
    The galvanic nickel layer solidly fixes warp and weave of the fabric
  • High abrasion resistance
    Not only for printing with abrasive inks, e.g. ceramic inks, but also during the cleaning process, no formation of ghost pictures
  • Easy lift-off from the printing stock
  • Antistatic
    Important in the textile industry and for the printing of plastics, including CDs. Static charges can create problems when polyester screens are used.
  • Electrically heatable up to 80°C
    For the decoration of high quality hollow glass, thermoplastic inks are used which have to be heated during the printing process. KGS mesh is very suitable for this technology because it is not only heatable but also >
  • More elastic and far less fragile than stainless steel mesh
    For example, KGS metallized fabrics are much less prone to kinking and follow the curvature of a hollow glass with little risk of damage which leads to >
  • Enhanced service life of the screens
    Depending upon the application
  • Since the base material for KGS metallized fabrics are high modulus/low elongation polyester fibre, usual stretching and processing parameters can be used to a large extent.
  • A side benefit
    Visual inspection for cleanliness is very easy since finger prints show up quite clearly on the surface. This is not the case with polyester mesh
