Benefits of technology

The patent text is about a new type of yarn used in electrical components, which is softer and more flexible than traditional yarns. This yarn can be formed by a multifilament yarn, which can be used as a core in the component. The use of a multifilament yarn core can provide improved restorative properties and reduced stiffness compared to a monofilament yarn, even if it has poorer compression hardness. This makes the yarn useful for reducing small gaps and minimizing the weight of electrical components, especially for mobile applications such as electric vehicles or photovoltaic systems.

Problems solved by technology

However, the spacer yarns are not provided with a continuous sheath, which would lead to substantial stiffening.

Embodiment Construction

[0042]FIG. 1 shows a spacer fabric in the form of a knitted spacer fabric with two cloth layers 1 and first and second spacer yarns 2a and 2b that extend transversely between the planes of and connect the layers 1. FIG. 1 and the detail view of FIG. 2 show that the spacer yarns 2a and 2b are configured differently. The first spacer yarns 2a each have a core 3 formed by a multifilament yarn and a helical wrapping 4 around the core 3. The wrapping 4 is made of metal or has at least one metallic layer.

[0043]It can already be seen from the detailed view of FIG. 2 that, if desired, good electrical conduction can also be achieved by the metallic wrapping 4 transversely, in the direction of thickness, the other spacer yarns 2b are formed of polymeric monofilaments.

[0044]The different spacer yarns 2a and 2b extend similarly between the two cloth layers 1 and also are of a similar thickness. While the metal-wrapped first spacer yarns 2a ensure good conduction of heat and electricity, the sec...

Abstract

A spacer fabric has two transversely spaced cloth layers. First spacer yarns bridge and transversely connect the cloth layers and are each formed by a core yarn and a helical wrapping made of metal or having a metallic layer. Second spacer yarns also bridge and transversely connect the cloth layers but are of different construction from the first yarns.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a spacer fabric. More particularly this invention concerns a knitted spacer fabric and a use thereof.BACKGROUND OF THE INVENTION[0002]A typical spacer fabric comprises two usually substantially flat or planar cloth layers and spacer yarns that transversely bridge and interconnect the cloth layers. Some of the spacer yarns and optionally even all of the spacer yarns having a core made of a yarn and a spiral wrapping.[0003]Spacer fabrics and, in particular, knitted spacer fabrics are characterized by a light, air-permeable structure, with spacer fabrics generally having an elasticity in the transverse direction of their thickness as a result of spacer yarns that run between the two cloth layers. By virtue of these properties, knitted spacer fabrics are often provided as a soft, elastic layer that enables air circulation in mattresses, upholstered furniture, garments, or shoes. A conventional knitted spacer fabric is known fr...
