Abstract:
An adhesive cable winding tape with anti-noise properties, comprising:a tape-like textile support (1); and a pressure sensitive adhesive coating (2) applied to one side of the tape-like textile support, the adhesive coating consisting essentially of synthetic rubber adhesive having a surface density of 130 g/m2; the tape-like textile support consisting essentially of a needle punched nonwoven which is fabricated of a first fiber material consisting essentially of polypropylene fibers and a second fiber material consisting essentially of polyethylene terephthalate fibers, and which has a basis weight of 100 g/m2; in which said first fiber material and second fiber material are bonded to each other on another side of the tape-like textile support opposite the adhesive coating by melting at a predetermined temperature; said two fiber materials having different melting points, whereby the melting point of said first fiber material is not less than 150Â° C. and lower than said predetermined temperature, and the melting point of said second fiber material is higher than 200Â° C. and higher than said predetermined temperature; and wherein the polypropylene fibers and the polyethylene terephthalate fibers each have a thickness of essentially 4.4 dtex and a length of essentially 60 mm, whereby the adhesive tape can be wound onto itself without use of release sheets or release coatings and unwound easily ready for use without tearing of the fibers.
