ADHESIVE TAPE FOR WRAPPING CABLES

Abstract

The invention relates to an adhesive tape, in particular wrapping tape, for sheathing automotive cables, having a textile support and at least one adhesive coating layer applied to one side or both sides of the textile support, and the textile support being manufactured entirely or partially from bio-based polymer fibers and/or polymer yarns, characterized in that the textile support is constituted of multi-weft yarns and/or multi-warp yarns.

Claims

1. An adhesive tape for wrapping cables in automobiles, the tape comprising: a textile substrate band made entirely or partially of bio-based polymer fibers and/or polymer filaments and composed of multicomponent weft yarns and/or multicomponent warp yarns; and an adhesive coating covering one or both faces of the textile substrate band.

2. The adhesive tape according to claim 1, wherein the textile substrate band consists of monocomponent warp filaments and multicomponent weft yarns.

3. The adhesive tape according to claim 1, wherein the monocomponent warp filaments have a filament thickness of at least 100 dtex.

4. The adhesive tape according to claim 1, wherein the multicomponent weft yarns each have a filament thickness of at least 100 dtex.

5. The adhesive tape according to claim 1, wherein the multicomponent warp yarns and/or the multicomponent weft yarns consist of filaments on a biopolyamide or bio-polyester base.

6. The adhesive tape according to claim 5, wherein monomers of the biopolyamide are completely or partially made from castor oil.

7. The adhesive tape according to claim 1, wherein 10 to 80 weft yarns/cm are provided in the textile substrate band.

8. The adhesive tape according to claim 1, wherein 10 to 50 warp yarns/cm are provided in the textile substrate band.

9. The adhesive tape according to claim 1, wherein the multicomponent weft yarns are at least double weft yarns.

10. The adhesive tape according to claim 1, wherein the weight per unit area of the textile substrate band is between 50 g/m.sup.2 and 500 g/m.sup.2.

11. The adhesive tape according to claim 1, wherein the textile substrate band is formed in only one layer.

12. The adhesive tape according to claim 1, wherein a material thickness of the textile substrate band is less than 0.8 mm.

13. The adhesive tape according to claim 1, wherein the adhesive coating has a rate per unit area of the band from 20 g/m.sup.2 to 200 g/m.sup.2.

14. The adhesive tape according to characterized claim 1 wherein the adhesive of the adhesive layer is a synthetic-rubber adhesive, a hot-melt adhesive, an acrylate-based adhesive, or an adhesive based on silicone, polyethylene, polyether and/or polyolefin.

15. The adhesive tape according to claim 1, wherein the adhesive coating is applied to the substrate over its entire surface or in strips.

Description

[0027] The invention is described in more detail below with reference to a drawing showing only one embodiment. Therein:

[0028] FIG. 1 is a top view of the textile substrate band of the adhesive tape according to the invention and

[0029] FIG. 2 is a schematic section through the adhesive tape according to the invention.

[0030] The drawing shows show an adhesive tape for wrapping cables in automobiles. In fact, the adhesive tape is normally used in a limiting manner by being be wound around a cable bundle or a cable set in a spiral or helical movement. For this purpose, the adhesive tape has, in its basic construction, a textile substrate band 1 and an adhesive coating 2 on only one face thereof. According to the embodiment, the adhesive coating 2 is applied over one entire face of the textile substrate band 1.

[0031] The plan view in FIG. 1 shows that the textile substrate band 1 is composed of warp yarns 1a and weft yarns 1b that according to the embodiment are woven together in a plain weave. A further special feature is that the textile substrate band 1 is composed of monocomponent warp filaments 1a and double weft yarns 1b.

[0032] This means that the weft yarns or double weft yarns 1b are in each case two individual weft yarns that are shot into a shed of the warp yarns 1a in the course of weaving. As a result, the adhesive tape made in this way has a high abrasion resistance on the one hand and, on the other hand, manual tearability in the transverse direction or parallel to the double weft yarns 1b.

[0033] According to the embodiment, the monocomponent warp filaments 1a and the double weft yarns 1b each consist of filaments on a biopolyamide or bio-polyester base. In the context of the embodiment, 10 to 50 monocomponent warp filaments 1a per centimeter are used in the textile substrate band 1. The number of double weft yarns in the textile substrate band 1 is between 5 and 40 double weft yarns 1b per centimeter.
