## Abstract

A textile fabric includes a textile fabric layer, a transparent film layer provided on the textile fabric layer, and a surface layer disposed on the transparent film layer. The transparent film layer has a two-layer structure including a first film layer having a first polyetherester-based copolymer and a second film layer having a second polyetherester-based copolymer disposed on the first film layer. The second film layer is provided on the textile fabric layer. A method of manufacturing the fabric includes preparing the textile fabric layer, forming the transparent film layer on the fabric layer, and laminating the textile fabric and transparent film layers through heat treatment.

## Claims

### Claim 1

A textile fabric comprising:
a textile fabric layer; and
a transparent film layer disposed on the textile fabric layer,
wherein the transparent film layer comprises a first film layer having a first polyetherester-based copolymer and a second film layer having a second polyetherester-based copolymer,
wherein the second film layer is disposed on the textile fabric layer, and
wherein a melting point of the second film layer is lower than a melting point of the first film layer.

### Claim 2 (depends on 1)

The textile fabric of claim 1, further comprising a surface layer disposed on the first film layer, the surface layer including a polymer resin.

### Claim 3 (depends on 2)

The textile fabric of claim 2, wherein the polymer resin comprises polyurethane.

### Claim 4 (depends on 2)

The textile fabric of claim 2, wherein the surface layer has a thickness in a range of 0.005 millimeters (mm) to 0.02 mm.

### Claim 5 (depends on 1)

The textile fabric of claim 1, wherein the first film layer has a thickness in a range of 5 micrometers (μm) to 50 μm.

### Claim 6 (depends on 1)

The textile fabric of claim 1, wherein the second film layer has a thickness in a range of 50 μm to 100 μm.

### Claim 7 (depends on 1)

The textile fabric of claim 1, wherein the transparent film layer has a thickness in a range of 55 μm to 150 μm.

### Claim 8 (depends on 1)

The textile fabric of claim 1, wherein the first polyetherester-based copolymer has a melting point (Tm) in a range of 150° C. to 190° C., a hardness in a range of 20D to 30D (SHORE D hardness tester), and a melt index (MI) in a range of 10 to 50 grams per 10 minutes (g/10 min) (220° C./2.16 kilograms (kg)).

### Claim 9 (depends on 1)

The textile fabric of claim 1, wherein the second polyetherester-based copolymer has a melting point (Tm) in a range of 100° C. to 160° C., a hardness in a range of 15D to 25D (SHORE D hardness tester), and a melt index (MI) in a range of 10 to 40 g/10 min (230° C./2.16 kg).
