Highly abrasionproof strip for armouring cable harnesses in motorcars
View Patent ↗The invention relates to a highly abrasionproof and sound-absorbing strip for armoring cable harnesses, especially in motorcars, said strip consisting of a backing comprising a first covering layer A that is joined to a second layer C over the entire surface of the covering layer A in a fixed manner. According to the invention, the covering layer A consists of suede, a non-woven fabric, a woven fabric or a knitted fabric, especially a PET filament fabric or a polyamide fabric, and the layer C consisting of a porous flat structure such as a textile having an open, but stable, three-dimensional structure, a foam or an expanded film.
1. An abrasion-resistant and noise-suppressing tape for bandaging cable harnesses, the tape comprising a backing with a first outer layer A having a first side, wherein the first side of the first outer layer A is connected to a separate layer C over an entire area of the first side of the first outer layer A, wherein the separate layer C is connected on an open side to a second outer layer B over an entire area of a first side of the second outer layer B, wherein mechanical bond formation connects, without adhesive, the first outer layer A and the separate layer C and connects, without adhesive, the second outer layer B and the separate layer C to form the backing, wherein
the first outer layer A is composed of a velour, scrim, woven fabric or formed-loop knit,
the second outer layer B is composed of a velour, scrim, woven fabric or formed-loop knit,
the separate layer C is composed of a textile having an open but stable three-dimensional structure, and
the separate layer C is a spacer knit, a loop product, a three-dimensional nonwoven structure or a warp knit and the separate layer C has a basis weight of 100 to 500 g/m 2 and a density of 100 to 600 g/dm 3 .
2. The abrasion-resistant and noise-suppressing tape according to claim 1 , which exhibits an abrasion resistance of the backing (measured in accordance with ISO 6722, section 9.3, “Scrape abrasion resistance”) of at least 150% of the sum of the abrasion resistances of the individual first outer layer A, the second outer layer B and the separate layer C.
3. The abrasion-resistant and noise-suppressing tape according to claim 1 , wherein the separate layer C has a thickness of 0.2 to 3 mm.
4. The abrasion-resistant and noise-suppressing tape according to claim 1 , wherein the first outer layer A, the second outer layer B, and the separate layer C comprise wear-resistant polymers.
5. The abrasion-resistant and noise-suppressing tape according to claim 1 , wherein a second side of the second outer layer B is coated with a self-adhesive layer, wherein the second side of the second outer layer B is located opposite to the first side of the second outer layer B and the separate layer C.
6. The abrasion-resistant and noise-suppressing tape according to claim 1 , wherein the mechanical bond formation comprises an interlooping, a stitching, a needling, a hydroentangling, an overstitching or an intermeshing.
7. The abrasion-resistant and noise-suppressing tape according to claim 1 , wherein the mechanical bond formation comprises the separate layer C intermeshed with the first outer layer A and the separate layer C intermeshed with the second outer layer B.
8. A method of wrapping an elongate product comprising guiding the abrasion-resistant and noise-suppressing tape according to claim 1 in a helical spiral around the elongate product.
9. A method of wrapping an elongate product comprising sheathing the elongate product with the abrasion-resistant and noise-suppressing tape according to claim 1 in its axial direction.
10. An elongate product wrapped with the abrasion-resistant and noise-suppressing tape according to claim 1 .
11. A vehicle comprising the elongate product according to claim 10 .
