Abstract

A digital garment and a fabrication method thereof are provided. The digital garment is fabricated using a knitting technique. The digital garment comprises a plurality of knitting yarns forming loops at regular intervals and interwoven through the loops, and one or more conductive digital yarns tied to the loops of the knitting yarns to form high-speed information communication circuits. The knitting yarns and the digital yarns are knitted together into a garment. During knitting, the digital yarns are used to form high-speed information communication circuits in a rapid and economical manner.

Claims

1. A digital garment comprising

a plurality of knitting yarns forming loops at regular intervals and interwoven through the loops, and

one or more digital yarns woven with the knitting yarns and through which a current flows,

wherein the knitting yarns and the digital yarns are knitted together into a garment.

2. The digital garment of claim 1, wherein the digital yarns are woven in the horizontal or vertical direction with respect to the loops of the knitting yarns.

3. The digital garment of claim 1, wherein the digital yarns form loops at regular intervals and the loops of the digital yarns are tied to the loops of the knitting yarns.

4. The digital garment of claim 1, wherein the digital yarns form loops at regular intervals and the loops of the digital yarns are tied to loops of other digital yarns.

5. The digital garment of claim 1, wherein the digital yarns are knitted in a wave-like pattern with the knitting yarns or another digital yarn.

6. The digital garment of claim 1, wherein the knitting yarns and the digital yarns are knitted into a mesh stitch, a cable stitch, a rib stitch, a plain stitch or a combination thereof.

7. The digital garment of claim 1, wherein the digital garment comprises a body portion and arm portions disposed opposite to each other at both sides of the body portion, the body portion and the arm portions being integrally knitted without any seams, and the digital yarns being woven with the knitting yarns from one of the arm portions to the other arm portion via the body portion.

8. The digital garment of claim 7, wherein the digital yarns are knitted with the knitting yarns in the horizontal or vertical direction with respect to the body portion.

9. The digital garment of claim 1, wherein a device selected from soft touch pads, electric screens, sensors, wireless communication modules, computing devices and electric modules is electrically connected to each end of the digital yarns.

10. The digital garment of claim 1, wherein the knitting yarns are single-ply yarns or multiple-ply yarns.

11. The digital garment of claim 1, wherein each of the digital yarns includes at least one metal line positioned at the center of the cross section thereof to provide a communication path, and a coating layer surrounding the metal line to shield electromagnetic waves.

12. A method for fabricating a digital garment, the method comprising:

selecting a particular garment design from a plurality of predetermined garment designs;

selecting a particular circuit design from a plurality of predetermined circuit designs;

knitting a plurality of knitting yarns so as to conform to the selected garment design and knitting one or more digital yarns to form circuits corresponding to the selected circuit design between the knitting yarns;

stitching the knitted fabric to fabricate a garment; and

electrically connecting electronic devices to the circuits of the digital yarns in the garment.

13. The method of claim 12, wherein in the garment design selection step, a coat garment design is selected in which a body portion and arm portions are disposed opposite to each other at both sides of the body portion;

and in the knitting step, the knitting yarns and the digital yarns are knitted without any seams between the body portion and the arm portions, and the digital yarns are integrally knitted from one of the arm portions to the other arm.

14. The method of claim 12, wherein the garment design selection step, the circuit design selection step and the knitting step are carried out using a knitting machine, the knitting machine comprising an input unit for selecting a garment design, a circuit design and a knitting program, a control unit for loading the garment design, the circuit design and the knitting program from a memory in response to input signals of the input unit to process the loaded data, an actuator mechanically operating in response to control signals of the control unit, and a cam operated by the actuator.

15. The method of claim 12, wherein in the knitting step, the circuits are formed by knitting the digital yarns in the horizontal or vertical direction with respect to the garment.
