Description

Partial stretchable conductive planar body {ELECTRIC CONDUCTION PLANAR ELEMENT WITH PARTIAL ELASTICITY}

The present invention relates to a partially stretched conductive planar body, and more particularly, a portion that requires elasticity in constructing a planar body on which a power supply line, an electric signal transmission line, and a conductive line serving as a heating line are arranged. The part formed by the structure and unnecessary elasticity relates to a part stretched conductive planar body which is formed to have a non-stretched structure.

In general, fabrics such as knitted fabrics and woven fabrics (hereinafter referred to as woven fabrics) used in the manufacture of bed covers, curtains, and clothes, are manufactured by natural or artificial fiber yarns. Each of them has its own properties and properties such as heat retention, water absorption, elasticity, and so on.

In addition, as the industrial society is advanced and advanced, modern people are demanding a woven fabric having a new function in addition to the warmth that can prevent the cold, the elasticity that ensures sufficient activity, and the absorbency that can absorb sweat as in the past. .

For example, the electric current can be supplied, so that various electronic devices can be installed and used conveniently, and require a woven fabric that performs heating or cooling by itself. This, because the woven fabric is light and thin, but can be used regardless of season bed, intelligent clothing, and the like.

Accordingly, in the field of textiles, various efforts and R & D activities have been carried out to satisfy these social needs and lead the future field of textiles. As a representative research achievement, a planar heating element composed of carbon fiber yarns has been developed.

Thus, the planar heating element woven by carbon fiber yarns can be applied to articles requiring heat action because it generates heat during power supply. It can not be applied to materials, garments that require elasticity and activity, and if continuous frictional force is applied during use, fine tissues of carbon fiber yarn are released and damaged or minute electric spark is generated, so sufficient durability and safety can be secured. Could not.

The planar heating element produced by has the limitation that it can not perform this function at all. As an alternative to this problem, a method of sewing a conductive wire such as copper wire separately to a garment may be proposed, but since copper wire has no elasticity at all, the activity and wearing comfort as clothing are poor, and the conductive wire and operation installed inside the garment during washing It is very inconvenient to use because it must remove the button.

The conductive wire 33 is disposed on the first non-stretch planar body 31, and the specific arrangement is selected from the forms (weaving method, embroidery method) mentioned in the first embodiment.

The elastic connecting member 34 is formed on both sides of the first non-stretch planar body 31 and is connected to the second non-stretch planar body 32 and is formed of an elastic structure or material which is stretched when the external force is applied. In addition, the stretchable connection member 34 may be provided with various stretchable members that are stretched when the external force is applied, such as a rubber band, and are retracted when the external force is released. An elastic band-shaped woven fabric in which the tip portion is fixed to the first non-stretched spherical body 31 and the rear end portion is fixed to the second non-stretched spherical body 32, and the elastic polymer yarn is supplied as a part of the weft yarn and the warp yarn together with the fiber yarn. Weaving is applied.

The first non-stretch planar body 31 may be sewn onto the second non-stretch planar body 32 and fixedly coupled thereto, but in the present embodiment, the first non-stretch planar body 31 and the second non-stretch planar body 31 may be fixedly coupled. Detachment means (37) consisting of female and male velcro fasteners (371,372) is provided between the planar bodies (32) so that they can be attached to and detached from each other as necessary. At this time, the detachable means 37 may be installed by applying a zipper or one-touch button.
