EP0281526A1 - Textile product with the presence of wire made of electrically conductive material, having the function of discharging static electricity - Google Patents

Abstract

A textile product (1) has a wire of electrically conductive material in its structure, having the function of discharging static electricity; said textile product may comprise stitch ranks formed by electrically conductive material (3) intercalated with stitch ranks formed by threads of textile material.

Description

• The invention relates to a textile product having special characteristics which are very useful for particular applications.
• It is known that often, in many utilizations of fabrics, a phenomenon of presence of electrostatic charges in the fabric or, anyhow, in the product of textile material, takes place, which charges cause troublesome and sometimes also dangerous effects due to the discharge of this electricity onto the skin or, anyhow, onto bodies coming into contact with the electrostatically charged products. The present product is realized to avoid these drawbacks.
• Substantially, the structure of the textile product according to the invention has a wire of electrically conductive material, having the function of discharging and distributing static electricity.
• Such product may be knitted with stitch ranks formed by a wire of electrically conductive material, intercalated with stitch ranks formed by threads of textile materials.
• Said wire of electrically conductive material may be a thin copper wire.
• The product may have the knitted structure making up the base for the anchorage of a fleece for the manufacturing of blankets and other.
• The attached drawing very schematically shows in:
• Fig.1, a knitted textile structure with copper wires; and in
• Fig.2, a very schematic cross section.
• As can be seen by a visual examination of the sample and as shown in the drawing, the structure 1 - mostly made by knitting - has some ranks of yarn 3 of electrically conductive material and in particular of copper, these ranks being spaced apart by ranks made of normal textile material. This presence of thin leads ensures an effective discharge of static electricity, which can be easily discharged and anyway distributed uniformly on the product without concentration. In Fig.1 numeral 3A indicates a seam respectively a selvedge or other, realized with filiform conductive material, such as a copper wire, ensuring the electrical connection among the various ranks of electrically conductive material for the above purposes, when the continuity is not already ensured by the same continuous knitting carried out without cutting the wire of the electrically conductive material. For the sake of explanation the drawing shows an interlacing, that may anyhow vary.
• Obviously, the wire made of copper or similar material will be particularly thin and may advantageously be of the type of wire like those used for the formation of windings in electrical machines such as electrical motors and other.
• The structure of the fabric may be a basic structure for the formation of a fleece V, as shown in Fig.2, wherein the fibres are anchored to the fabric 1, 3 in a manner known per se, in order to form these fleece products. The material of the fleece V is not illustrated in Fig.1.
