Background technology
Metal fibre, especially wire are known as the element of conduction strand.For example, the conduction strand is used as Thermal Cutoffs in US5927060, perhaps for example is used for eliminating the electrostatic charge that woven textile products accumulates described in the US3288175.
Known conductive elastic composite yarn from WO2004/097089.The document (preamble of first claim is based on it) has been described electrically conductive elastic composite yarn, this strand comprises at least one elastomeric element with ratio N, this ratio N is the tensile elongation Ld of elastomeric element and the ratio of relaxed length Lr, and in the scope of 1-8.This strand can comprise the wire around the elastomeric element of being wrapped in more than.Wire has the length of the tensile elongation that equals elastomeric element at least.Strand has such advantage, and promptly when strand was subjected to elongating, wire was not subjected to tensile stress.
Yet this strand has some shortcomings.Because the wire in every linear meter strand of strand has very long length, wire is not easy to contact with the outer surface of elastomeric element very much.Thus, wire is not in tension force following time at elastomeric element has the freedom that moves at random around elastomeric element.When this strand was used to textile fabrics is provided, some wire rings can be stretched out from textile fabrics easily owing to random deformation wiry.When textile fabrics was stretched repeatedly, such phenomenon appearred usually.
Freely-movable wiry also can make the electrical property of strand produce some less variations, because behind each stretching textile fabrics, in strand, between the adjacent ring of same silk or be used for forming the contact point that occurs varying number between several silks of same strand.
The situation that wire may be not contact with following elastomeric element also may cause more frequent silk disrumpent feelings, perhaps may disturb the production of the woven textile products of wherein using strand, perhaps may be because the use that wire stretches out the surface disturbance textile fabrics of textile fabrics.
The situation that wire contacts with following elastomeric element can greatly increase the so-called flex life of electrically conductive elastic composite yarn.
