Adhesive tape for wrapping cables
An adhesive tape for bundling cables is made by first making a velour substrate band entirely or partially of bio-based polymer fibers and/or bio-based polymer filament and having a front face from which projects a dense array of loops and a back face. Then an adhesive coating is applied to a back face of the substrate band to make therefrom an adhesive tape meeting abrasion class C of LV 312. This adhesive tape is used by being wound around a plurality of motor-vehicle cables with the adhesive engaging the cables and the front face and loops turned away from the cables.
1. A method comprising the steps of:
making a velour substrate band entirely or partially of bio-based polymer fibers and/or bio-based polymer filament and having a front face from which projects a dense array of loops and a back face;
applying an adhesive coating to a back face of the substrate band to make therefrom an adhesive tape meeting abrasion class C of LV 312; and
winding the adhesive tape around a plurality of motor-vehicle cables with the adhesive engaging the cables and the front face and loops turned away from the cables.
2. The method according to claim 1 , further comprising the step of:
forming the velour substrate band has with outwardly facing velour loops with a loop length from 0.5 mm to 5 mm.
3. The method according to claim 1 , further comprising the step of:
imparting to the velour substrate band has a mesh density of more than 5000 per dm 2 .
4. The method according to claim 1 , wherein the velour substrate band is produced by knitting and formed with outwardly directed velour loops in the form of a n surface-bonded outer layer.
5. The method according to claim 1 , wherein the velour substrate band is made from filaments based on biopolyamide or bio-polyester.
6. The method according to claim 5 , wherein monomers of the biopolyamide consist entirely or partially of castor oil.
7. The method according to claim 1 , wherein the substrate band is formed as a laminate and also has a film layer.
8. The method according to claim 7 , wherein the film layer is between the velour substrate band and the adhesive coating.
9. The method according to claim 7 , wherein the film layer is a bio-based polymer film.
10. The method according to claim 9 , wherein the film layer is a biopolyester film.
11. The method according to claim 1 , wherein the substrate band is formed to have has a basis weight of 20 g/m 2 to 500 g/m 2 .
12. The method according to claim 1 , wherein the substrate band has a material thickness of 0.5 mm to 3 mm.
13. The method according to claim 1 , wherein the adhesive coating has an application weight from 20 g/m 2 to 200 g/m 2 .
14. The method according to claim 1 , wherein the adhesive used is a synthetic rubber adhesive, a hot-melt adhesive, an acrylate-based adhesive, or a silicone-, polyurethane-, polyether- and/or polyolefin-based adhesive.
15. The method according to claim 1 , wherein the adhesive coating is applied to the substrate band over the entire back face or in strips.
