Abstract

An adhesive tape particularly for wrapping cables comprises a textile carrier and a pressure-sensitive adhesive applied on at least one side of the carrier, where starting materials used for the textile carrier comprise fibres of recycled polyethylene terephthalate, where the fraction of the fibres is at least 50 wt % and where the fibres are staple fibres or continuous filaments or are processed to form yarns.

First claim

1 . An adhesive tape comprising a textile carrier and a pressure-sensitive adhesive applied on at least one side of the carrier, where starting materials used for the textile carrier comprise fibres of recycled polyethylene terephthalate, where a fraction of the fibres is at least 50 wt % and where the fibres are staple fibres or continuous filaments or are processed to form yarns.

2 . Adhesive tape according to claim 1 ,
wherein the fraction of the fibres in the textile carrier is more than 50 wt %, preferably 70 wt % or more, more preferably 90 wt % or more, more preferably 100 wt %.

3 . Adhesive tape according to claim 1 ,
wherein the fraction of the fibres in the textile carrier is 100 wt %.

4 . Adhesive tape according to claim 1 ,
wherein the carrier is a textile carrier, preferably a nonwoven material or a woven fabric, more particularly a polyethylene terephthalate nonwoven.

5 . Adhesive tape according to claim 1 ,
wherein the textile carrier material comprises stitchbonded fabrics, these being textile sheetlike structures which are produced by looping of incorporated knitting threads into a sheetlike base material, and preferably stitchbonded nonwovens, these being textile sheetlike structures with fibre nonwoven as base material which are consolidated by looping of incorporated knitting threads, or by overstitching with additional stitching yarn.

6 . Adhesive tape according to claim 1 ,
wherein the textile carrier material comprises knit-bonded nonwovens, these being textile sheetlike structures which are produced, without using threads, by formation of fibre loops from primary fibre nonwoven, and preferably stitchbonded nonwovens, these being textile sheetlike structures with fibre nonwoven as base material which are consolidated by looping of incorporated knitting threads.

7 . Adhesive tape according to claim 1 ,
wherein the textile carrier material comprises stitchbonded nonwovens in the form of Maliwatts, preferably having a basis weight of 50 to 200 g/m 2 more particularly 65 to 190 g/m 2 , having a linear fibre density of 2 to 5 denier, a fibre length of 30 to 90 mm and/or a stitching thread count of 15 to 25 threads/25 mm.

8 . Adhesive tape according to claim 1 ,
wherein the carrier is woven fabric and more preferably is constructed as follows:
a thread count in a warp is 10 to 60/cm
a thread count in a weft is 10 to 40/cm
warp threads possess a yarn weight of between 40 and 400 dtex, more particularly between 44 and 330 dtex, very preferably of 167 dtex
weft threads possess a yarn weight of between 40 and 660 dtex, more particularly between 44 and 400 dtex, very preferably of 167 dtex.

9 . Adhesive tape according to claim 1 ,
which has an adhesive coatweight, based on an area of the carrier, is between 40 and 160 g/m 2 , preferably between 50 and 100 g/m 2 , more preferably between 50 and 90 g/m 2 .

10 . Adhesive tape according to claim 1 ,
wherein the adhesive comprises a self-adhesive coating, preferably based on natural rubber and/or synthetic rubber, acrylate or silicone, preferably natural and/or synthetic rubber.

11 . A method of jacketing an elongate item comprising guiding an adhesive tape according to claim 1 in a helical line around the elongate item.

12 . A method for jacketing an elongate item comprising enveloping the elongate item in an axial direction by an adhesive tape according to claim 1 .

13 . An elongate item jacketed with an adhesive tape according to claim 1 .

14 . A vehicle comprising a jacketed elongate item according to claim 13 .
