  • Basic knit yarns were knitted, stitched to the unoccupied needles of the left side of the fabric forming the first needle bed by means of an elastic thread to form a float with mesh.
  • the elastic thread is thus knitted with a stitch on those needles that are right and / or left of a now empty needle, because previously suspended loop.

  • Knitted fabric would press. Rather, the knit stitches appear in these non-overhanging areas and form the fabric inside. A significant adhesive effect is not given in this area. The stitches, knitted with the elastic thread, step back, they pull into the fabric, the adhesive effect in this area inevitably decreases. This means that patterns can be redistributed in a pattern, and / or in blocks, in order to only partially infiltrate the "adhesive tape".

  • stitches 10 of the elastic thread which are knitted on the rear needle bed 1. That means that the knitted interior is much elastic
  • Thread material is given. Since the elastic thread, be it the silicone thread, be it the elastane thread, has a corresponding adhesive property and since the stitches 10 are highlighted or raised, this results in a corresponding adhesion area, which can be seen solely in the knitted longitudinal direction given rows of stitches of the 10 elastic thread 4 is formed. The adhesive properties are remarkably good because they are not affected by the crushed back stitches 8 of the non-adherent base stitch thread.
