Definitions
- the invention relates to an adhesive tape which consists of a tape-shaped carrier based on a Kunitviieses or Muttikunitvlieses, which is either provided on its underside with an adhesive coating or on both sides with an adhesive coating.
- Adhesive tapes of this type are known.
- the band-shaped carrier is designed as a woven fabric or as a sewing nonwoven, fabric tapes having been on the market for a long time and tapes with a sewing nonwoven carrier are described in DE-GM 94 01 037.
- Pressure-sensitive PSA coatings are preferably used as the adhesive coating.
- Adhesive tapes with a fabric backing meet high technical requirements, but are complex to produce, expensive and tend to penetrate the adhesive.
- Adhesive tapes with a non-woven backing have a simple structure, but they show considerable disadvantages in practical use, such as inadequate recycling properties and problems due to the heterogeneous non-woven structure with reinforcing parallel seams.
- the present invention has for its object to improve an adhesive tape so that the disadvantages of the prior art do not occur or at least not to the extent.
- a fleece of the type Kunitviies or multikunit fleece is used as the carrier.
- a Kunitviies is characterized in that it results from the processing of a longitudinally oriented nonwoven fabric to a Flachengebi.de, which has loops on one side and mesh webs on the other side or poly fiber folds, but has neither threads nor prefabricated fabrics.
- Such a fleece has been produced for example on sewing-knitting machines of the "Kunitviies" type from Malimo for a long time and can be obtained from the companies Cottano GmbH and Techtex GmbH, among others.
- Another characteristic feature of this fleece is that it can absorb high tensile forces in the longitudinal direction as a longitudinal fiber fleece.
- a multikunit fleece is characterized in that the fleece is consolidated on both the top and the bottom by needles being pierced on both sides.
- polyester, polypropylene or cotton fibers are provided as starting materials for the carrier.
- the present invention is not limited to the materials mentioned, but a large number of other fibers can be used to produce the nonwoven.
- an additional coating of the second carrier side with acrylate lacquer may be sufficient, or a combination of foam and lacquer may be necessary.
- the lacquer or foam and lacquer are applied to the top of the carrier, which is characterized in that it is the smoother of the two sides of the fleece.
- the carrier is preferably coated by the method described below. If a coating of the carrier with foam and varnish is provided, an acrylic dispersion is first foamed onto the carrier material using the doctor blade method. The resulting intermediate product is then calendered in order to achieve a densification and crosslinking of the foam layer before a lacquer layer made of acrylate lacquer is also applied over the foam layer by the doctor blade method.
- the adhesive side of the carrier can be coated in a conventional manner, in particular with a self-adhesive coating.
- Conventional coating with a coating bar and solvent masses is advantageous, but it is better to do this in a contactless or almost contactless manner using screen printing technology (cf. DE - PS 3.346.100), a full-surface or segment-like adhesive coating being conceivable.
- screen printing technology cf. DE - PS 3.346.100
- a full-surface or segment-like adhesive coating being conceivable.
- reference is expressly made to this patent DE-PS 3,346,100 in particular to the viscosity and type of adhesive, to the sieves used, web speeds and other measures.
- the coating by means of roller slot nozzle application in particular for hot-melt adhesive, can also be used.
- a natural rubber / resin is applied to a Kunitviies carrier with a basis weight of 100 g / m 2 , which can be obtained from Techtex GmbH, using a doctor blade method at a web speed of 50 m / min and a temperature of 60 ° C as an adhesive / Gasoline adhesive applied. Drying in the slopes is also carried out at a temperature of 60 ° C.
- An acrylate dispersion (water content: 50% by weight) is first foamed onto the uncoated backing fleece side in a streak dryer in a line using the doctor blade method, the doctor blade taking up a position of 25 ° to the zenith of the coating lower roller.
- the preliminary product is pre-dried at an average temperature of 120 ° C and then calendered in-line at a temperature of 150 ° C to 180 ° C and a pressure of 10 tons.
- the back of the foam-coated carrier is also coated in a stenter dryer at a web speed of 50 m / min, with ten grams of halogen-free acrylate coating (Primal 225 from Rohm and Haas) being coated per square meter.
- the paint layer dries at 160 ° C in the stenter dryer, which also causes the foam to condense. If only one layer of paint or no coating is desired, the corresponding steps in the manufacturing process are omitted.
