## Abstract

A fabric coated with functional silicone rubber, the fabric being configured such that a coating layer may not be easily separated from the fabric and may be used to form a power line or a signal line. The fabric includes: a woven fabric made by weaving and including uniform pores therein; and a coating layer formed by coating a surface of the woven fabric with liquid silicone rubber in which electrically conductive particles larger than the pores of the woven fabric are dispersed and mixed, wherein the liquid silicone rubber permeates into the pores of the woven fabric by the weight thereof and is cured such that the silicone rubber is anchored to the woven fabric, and an electrically conductive layer having electrical conductivity is formed as the electrically conductive particles are caught on the surface of the woven fabric and increase in density at the surface of the woven fabric.

## Claims

### Claim 1

A fabric coated with functional silicone rubber, the fabric comprising:
a woven fabric made by weaving and comprising uniform pores therein; and
a coating layer formed by coating a surface of the woven fabric with liquid silicone rubber in which electrically conductive particles larger than the pores of the woven fabric are dispersed and mixed,
wherein the liquid silicone rubber permeates into the pores of the woven fabric by the weight thereof and is cured such that the silicone rubber is anchored and coupled to the woven fabric, and
an electrically conductive layer having electrical conductivity is formed as the electrically conductive particles are caught on the pores of the woven fabric at an interface with the woven fabric and increase in density at the interface.

### Claim 2 (depends on 1)

The fabric coated with functional silicone rubber of claim 1, wherein the coating layer is formed by dispersing and mixing electrically conductive wires together with the electrically conductive particles in the liquid silicone rubber and curing the liquid silicone rubber.

### Claim 3 (depends on 2)

The fabric coated with functional silicone rubber of claim 2, wherein the electrically conductive wires have elasticity and restoring force in a length direction thereof and are irregularly tangled with each other in the silicone rubber.

### Claim 4 (depends on 2)

The fabric coated with functional silicone rubber of claim 2, wherein the electrically conductive wires comprise an electrically conductive fiber and electrically conductive fine metal wires and have a spring shape having gaps between turns, a zigzag shape, or a hook shape.

### Claim 5 (depends on 4)

The fabric coated with functional silicone rubber of claim 4, wherein the electrically conductive wires have a single fiber, wool, or mesh structure.

### Claim 6 (depends on 1)

The fabric coated with functional silicone rubber of claim 1, wherein as the electrically conductive particles move downward in the coating layer, the electrically conductive particles gradually decrease in density in a direction from the interface with the woven fabric toward a surface of the coating layer such that the surface of the coating layer has no or low electrical conductivity.

### Claim 7 (depends on 1)

The fabric coated with functional silicone rubber of claim 1, wherein the electrically conductive particles have uniform density as a whole up to a surface of the coating layer in a thickness direction of the coating layer except for the electrically conductive layer such that the surface of the coating layer has electrical conductivity.

### Claim 8 (depends on 7)

The fabric coated with functional silicone rubber of claim 7, wherein an electrically conductive electrode is formed by coating the surface of the coating layer with electrically conductive liquid silicone rubber in which carbon powder is dispersed and mixed, and curing the electrically conductive liquid silicone rubber.

### Claim 9

A functional garment comprising a garment fabric, an adhesive pattern for making contact with the skin of a person being attached to an inner side of the garment fabric,
wherein the fabric comprises: a woven fabric made by weaving and comprising uniform pores therein; and a coating layer formed by coating a surface of the woven fabric with liquid silicone rubber in which electrically conductive particles and electrically conductive wires larger than the pores of the woven fabric are dispersed and mixed,
wherein the liquid silicone rubber permeates into the pores of the woven fabric by the weight thereof and is cured such that the silicone rubber is anchored and coupled to the woven fabric,
wherein the electrically conductive wires have elasticity and restoring force in a length direction thereof and are irregularly tangled in the silicone rubber.
