Definitions

  • the invention relates to a method for producing a fabric web, especially for use as a screen printing form a non-metallic fabric with a cladding layer provided and then galvanically coated with a metal is coated.
  • the invention covers a tissue of its own crossing strands, especially a screen printing fabric, which after this process is made.
  • the screen printing process is - centuries after its first Application in China - since about the 19th century in Europe known; a fine-mesh textile or wire mesh is in stretched over a screen printing frame and in the non-image areas covered opaque.
  • manual cutting templates for example for inscriptions - are preferred photographically today manufactured direct or indirect stencils common; the choice of stencil type - for direct stencils with emulsion, with direct film and emulsion or with direct film and water - left to the screen printer.
  • a screen printing fabric is placed over one Print frame made of light metal, wood or the like. stretched and in its clamping position glued to the printing frame. A cleaning of the fabric allows the subsequent application of a light sensitive Emulsion, for example using a coating trough manually or mechanically with a coating machine. Because the coating is not exactly to the inside of the frame can be generated, the remaining area must be added sealed with a screen filler. Now the coated one Area by means of a copy template corresponding to the print image (Film) exposed. The unexposed areas of the printed image are washed out. After the template has dried, this is done Retouch and cover the edges with a screen filler.
  • plastic nets For certain areas of application, it is known for plastic nets by chemical treatment of the surface on it Settling palladium seeds and metallizing the filaments. These chemical treatment processes run over several Levels and are in their compositions and processes to that to coordinate the respective plastic material. Restrictions on The choice of materials are due to poor or unsuitable Materials specified. To the well-known expensive pretreatments can expensive chemical metal deposition processes connect; because of their insufficient conductivity the pretreated plastic fabric surface not directly with galvanic metal deposition.
  • US-A-1 934 643 from 1930 describes a fabric electrically conductive material, the surface of which with a non-metallic cover layer or a cover layer made of pure Metal or an alloy, especially with nickel or chrome, by spraying, plating or chemical or galvanic process.
  • US-A-4 042 466 is a method of making a for use as a screen printing stencil made of a textile fabric manufactured fabric web, the latter with a metallic cover layer is provided.
  • the Plastic threads with a thin layer of metal for example copper with a thickness of 1 to 2 ⁇ m as the conductive one Intermediate layer coated and on this a nickel layer of 25 ⁇ m galvanized.
  • DE 32 43 190 A1 also deals with one continuous process for making metallized Textile fabrics with an electrically conductive Metal layer coated and then galvanically reinforced become.
  • the first metal layer can be by means of a wet chemical, currentless processes or by vapor deposition be applied.
  • a metallized, textile is created Flat structures with textile properties as before. On Gluing the mesh crossing points is undesirable.
  • a plastic fabric is made from both fabric sides several times by steaming or by so-called sputtering - by sputtering - for electroplating prepared, i.e. with a metallic cladding layer Surface resistance from 0.2 ohm / 2 to 200 ohm / 2 and then galvanically coated.
  • All treatment materials are freely selectable according to the invention as well as the subsequent electroplating.
  • nickel is preferred above all because of its chemical resistance; others here advantageously
  • the materials used are gold, silver, copper, steel or a light metal - especially aluminum - alone or as an alloy.
  • the steaming, sputtering or spraying process is used performed on both sides and repeated several times.
  • layer thicknesses of about 5 to over 200 nanometers - especially above 50 nm.
  • the Cathode sputtering - i.e. the sputtering mentioned - or Plasma spraying in vacuum becomes electrical conductivity of the fabric.
  • the mechanical properties of the metallized fabric are mainly determined by galvanization; the Elongation becomes striking with increased strength of the fabric reduced as well - regardless of the type of starting tissue - The sliding resistance of the fabric is extraordinary elevated. Above all, the metallizing substances wear for strength at the weakening points of the fabric Plastic base materials and form a conductive Surface. This makes it possible to use expensive metallic fabrics through metallized plastic fabrics with similar Properties to replace.
  • the metallized plastic fabric according to the invention ensures minimal stretching with sufficient Basic strength and causes hardly measurable There are register differences on the template, regardless of the tension set.
  • the full-surface coating of the limited flexible metallized fabric causes a high, reproducible Stencil quality with excellent edge sharpness and more precise Color dosing.
  • a protective film, if applicable reduces mishandling, which is a loss of Can cause coating quality. Since the Coating is carried out on the endless fabric roll, there is no need for masking work, as is common today.
  • the invention is primarily used to produce a screen printing stencil, however, fabrics can also be used for other uses are treated in the manner described, in particular Filter fabric or surface elements for shielding in Field of electronics.
  • a fabric 10 for making screen printing stencils is produced from intersecting warp threads 12 and weft threads 14, 1 in a so-called plain weave, in the case of a repeat - one by a certain number of binding sites 16 defined repetition units - two warp threads each 12 and two wefts 14 belong.
  • These threads 12, 14 can consist of any plastic base material, such as made of polyamide (PA), polyethylene (PE), polyethylene terephthalate (PET) or the like more.
  • the plastic fabric 10 is a roll continuously Steaming process subjected to the maximum web length due to the highest possible winding diameter in the Evaporation system is determined.
  • Gold for example, Silver, copper, nickel, steel, aluminum or the like.
  • the evaporation or sputtering process is carried out on both sides and, if necessary, repeated several times for special requirements.
  • This dry coating process can also be in the area each bond 16 lead to material accumulations, of which one between the crossing threads 12, 14 is indicated at 20.
  • Plastic mesh can now be used for direct galvanic metal deposition be made. Again, like any metals can be used, such as Cu, Ni or the like ..
  • the galvanic metallization can be considered as continuous Process carried out with practically any roll length become and leads to a closed metal coating 22nd selectable layer thickness e - from preferably 2 ⁇ m to 20 ⁇ m and more - over the entire fabric 10; this Metal coating 22 ensures both high mechanical Stability, especially sliding resistance, as well as for one chemical resistance of the metallized tissue 10; whose As I said, strength becomes clearer Decrease in stretchability increased significantly.
