Embodiment 1

[0185] Embodiment 1 (of the present invention)

[0186] Nylon 6,6 yarns (linear density 1100 decitex, and 140 filaments / yarn) from INVISTA were woven in a plain weave structure with a set of 13 warp yarns / cm and 12 weft yarns / cm, Produces a unit weight of 280g / m 2 . The obtained fabric exhibited an ultimate tensile strength of 680 N / cm, an elongation at break of 36% and a flexural stiffness of 0.044N. at 120g / m 2 Coating with an acrylate adhesive yielded tapes exhibiting LV312 wear class F on 5-mm and 10-mm mandrels.

Abstract

Highly abrasion-resistant tape, preferably for sheathing elongate material such as more particularly leads or cable looms, having a woven fabric backing, characterized in that the woven fabric is composed of a plastics material, the yarns used to form the fabric have a linear density of 280 to 1100 dtex, and each yarn is constructed from at least 90 single filaments.

Description

technical field [0001] The present invention relates to a highly wear-resistant belt, preferably for sheathing elongated materials, such as in particular leads or cable looms, comprising a backing and optionally and preferably A coating of pressure sensitive adhesive applied on at least one side of the backing.The invention also relates to the use of the tape and to cable harnesses wound with the tape of the invention. Background technique [0002] Many industries include bundling of multiple wires prior to installation or when already assembled in order to reduce the space taken up by the wire bundle and to obtain a protective function through bundling. Use film-backed tapes for some protection against fluid erosion; use hollow (airy) and bulky (bulky) tapes based on thick non-woven fabric or foam backing materials for insulating properties; when used with stable, Get protection against scratches and abrasions when wearing the backing material.
