Description
The present invention relates to a yarn for shielding electromagnetic waves capable of shielding electromagnetic waves.
The rapid development of information communication technologies render electronic machines occupy many spaces around us. Electronic components used in those electronic machines generate high frequency electromagnetic waves, which cause electromagnetic disturbance, electromagnetic interference, electromagnetic noise and the like.
Recent researches have found out that the electromagnetic waves have a considerably bad effect on human bodies as well as the peripheral devices. Consequently, controversy exists over harmfulness of electromagnetic waves.
Furthermore, the development of the information communication technologies makes mobile phones ubiquitous, accordingly, such electronic machines are used close to human bodies. Such environment further raises the interest in the electromagnetic waves.
Therefore, it is one object of the present invention to provide a yarn capable of shielding electromagnetic waves in a different form from the related art.
It is another object of the present invention to provide an electromagnetic wave shielding yarn which can be more easily weaved.
To achieve those objects of the present invention, there is provided an electromagnetic wave shielding yarn including a wick, a conductor and a coating unit. The conductor may be configured to be wound on the wick. At least part of the conductor may be made of a conductive material for shielding electromagnetic waves. The coating unit may wrap up the coating unit so as to coat the conductor.
In one aspect of the present invention, the conductor may be made of a filament of a conductive fiber. The conductive fiber may include a carbon fiber.
In another aspect of the present invention, the wick may be made of a flexible fiber. At least one of the wick and the coating unit may be made of a natural fiber or a synthetic fiber.
The present invention can implement an electromagnetic wave shielding yarn capable of being weaved so as to be a yarn of electromagnetic wave shielding fabrics by virtue of a wick and a coating unit. Also, the present invention can implement an electromagnetic shielding yarn which is flexible by virtue of the wick and configured such that a conductor can be protected by the coating unit.
Also, according to the present invention, the selection of diameters of the wick and the coating unit may allow the electromagnetic wave shielding performance of the electromagnetic wave shielding yarn.
FIG. 1 is an overview of an electromagnetic wave shielding yarn in accordance with one embodiment of the present invention; and
FIGS. 2 and 3 are overviews showing embodiments of fabrics which are produced by weaving the electromagnetic wave shielding yarns of FIG. 1.
Description will now be given in detail of a yarn for shielding electromagnetic waves according to the present invention, with reference to the accompanying drawings. This specification employs like/similar reference numerals for like/similar components irrespective of different embodiments, so they all will be understood by the first description. The expression in the singular form in this specification will cover the expression in the plural form unless otherwise indicated obviously from the context.
FIG. 1 is an overview of an electromagnetic wave shielding yarn 100 in accordance with one embodiment of the present invention.
As shown in FIG. 1, the electromagnetic wave shielding yarn 100 may include a wick 110, a conductor 120 and a coating unit 130.
The wick 110 may be disposed to serve as a core of the electromagnetic wave shielding yarn 100. The wick 110 may be made of a flexible fiber. Accordingly, even if an external force is applied to the electromagnetic wave shielding yarn 100, the electromagnetic wave shielding yarn 100 can be expanded and contracted up to a range near an expansion and contraction range of the wick 110.
The wick 110 may be made of a natural fiber or a synthetic fiber. For example, examples of the natural fiber may include cotton, wool, linen, silk and the like, and examples of the synthetic fiber may include nylon, polyester, acryl and the like.
The conductor 120 may be formed to be wound on at least part of the wick 110.
As shown in the drawing, the conductor 120 may be wound on the wick 110 at a constant interval, as similar to a screw thread formed on a bolt.
At least part of the conductor 120 may be formed of a conductive material, so as to shield electromagnetic waves. The phrase ‘shielding electromagnetic waves’ expressed in the specification of the present invention may all cover reflecting or absorbing electromagnetic waves.
The conductor 120 may be made of a filament of a conductive fiber. The conductive fiber may include a carbon fiber, for example.
The conductor 120 may be formed as a piece of string so as to wrap up the wick 110, which facilitates the expansion and contraction of the electromagnetic wave shielding yarn 100.
The coating unit 130 may be coated on the conductor 120 to protect the conductor 120.
Referring to the drawing, the coating unit 130 may cover the conductor 120 in an opposite direction to the direction that the conductor 120 wraps up the wick 110. Here, the present invention may not be limited to these directions. For example, the coating unit 130 may cover the conduct 120 in the same direction as the direction of the conductor 120 wrapping up the wick 110.
The coating unit 130 may cover not only the wick 110 but also the conductor 120, thereby preventing external exposure of the wick 110 and the conductor 120.
The coating unit 130 may be made of a natural fiber or a synthetic fiber. For example, examples of the natural fiber may include cotton, wool, linen, silk and the like, and examples of the synthetic fiber may include nylon, polyester, acryl and the like. Hence, the coating unit 130 can be dyed, which allows the electromagnetic wave shielding yarn 100 to have a color desired by a designer. The coating unit 130 may be made of the same fiber as the wick 110.
By virtue of the coating unit 130 covering the conductor 120, the core yarn 100 can have improved intensity and provide good tactile impression upon being weaved into fabrics. Also, it is enabled to adjust a diameter of the coating unit 130, accordingly, the designer can adjust periodic patterns of the weaved fabrics (see FIGS. 2 and 3).
FIGS. 2 and 3 are overviews showing embodiments of fabrics which are produced by weaving the electromagnetic wave shielding yarns of FIG. 1.
Referring to FIGS. 2 and 3, the electromagnetic wave shielding yarns 110 are used as yarns for fabrics 200 and 300.
Referring to FIG. 2, the fabric 200 may be produced by weaving three pieces of electromagnetic wave shielding yarns 100 with a stagger angle of 60° therebetween. Referring to FIG. 3, the fabric 300 may be produced by weaving the electromagnetic wave shielding yarns 100 to intersect with each other.
Interval and/or density of warp and weft of each fabric 200 and 300 may be adjusted as a designer selects a diameter d1 of the wick 110 and a diameter d3 of the coating unit 130 (see FIG. 1).
The adjustability of the interval and/or density of the fabrics 200 and 300 allows adjustment of electromagnetic wave absorption for each frequency. Consequently, the electromagnetic wave shielding yarn according to the present invention may be used as a yarn of a frequency selective filter. The frequency selective filter indicates a filter which selectively reflects or transmits and absorbs electromagnetic waves depending on a frequency band, and be used in an antenna.
The electromagnetic wave shielding yarn may not be limited to the construction and method illustrated in the foregoing embodiments. Many variations can be embodied by selective combination of all or part of the embodiments.
The electromagnetic wave shielding yarn may be industrially applicable.
