Problems solved by technology

[0006] The fact that the wire may not be in contact with the underlying elastic may also result in more frequent wire breakage, or may interfere with the production of textiles in which the strands are used, or may interfere with the use of the textile due to the wire sticking out of the surface of the textile

Embodiment Construction

[0046] figure 1 A strand 101 according to an example of the invention is schematically shown, comprising an elastic member 110 wound with metal wires, collectively indicated at 120 , twisted with each other. As an example, the elastic member 110 is a natural rubber wire and the wire 120 comprises 275 wires of stainless steel AISI316L with an equivalent diameter of 12 μm. These wires are twisted to each other at 100 turns per meter in the Z direction, and then wound around the elastic member 110 at 1100 turns per meter in the S direction.

[0047] The ratio N of the stretched length Ld to the relaxed length Lr of the elastic member was 1.4. For a relaxed length S of 100 mm of the strand 101 , the length of each wire is substantially equal, thus the same as the shortest length F of the wire. In this embodiment, F is 140mm.

[0048] The resistance of the strand 101 was 21 ohms / meter.

[0049] Alternatively, the wires 120 comprise 90 wires in alloy stainless steel AISI316L an...

Abstract

An electrically conductive elastic composite yarn comprises at least one elastic member having a ratio N being drafted length Ld over relaxed length Lr1 N being in the range of 1 to 10. The yarn further comprises more than one metal filament wrapped around the elastic member. The yarn is characterized in that each of the metal filaments is twisted with at least one other of the metal filaments.

Description

technical field [0001] The invention relates to a conductive elastic composite yarn and a textile product comprising the yarn. The invention also relates to the use of the textile product. Background technique [0002] Metal fibers, especially metal wires, are known as elements of electrically conductive strands. Conductive strands are used, for example, as thermal fuses in US5927060, or for dissipating static charges accumulated in textile fabrics, such as described in US3288175. [0003] Conductive elastic composite yarns are known from WO2004 / 097089. This document, on which the preamble of the first claim is based, describes an electrically conductive elastic composite strand comprising at least one elastic member having a ratio N of the stretched length Ld of the elastic member to the relaxed The ratio of length Lr, and in the range of 1-8. The strand may include more than one wire wrapped around the elastic. The wire has a length at least equal to the stretched len...
