Abstract

The present application relates to a coated fabric and an air bag comprising the same.

Claims (33)

1 . A coated fabric comprising: a fibrous substrate (A), and a coating layer (B) formed on the fibrous substrate,

wherein the coating layer comprises a binder resin and a filler,

wherein the filler is dispersed in the coating layer,

wherein the filler comprises agglomerates of chopped ceramic fibers having a size in the range of 0.1 to 2.0 mm,

wherein a coating amount of the coating layer to one layer of the fibrous substrate is 50 gsm to 100 gsm, and

wherein the coated fabric has a weight of 280 g/m 2 to 350 g/m 2 .

2 . The coated fabric according to claim 1 , wherein:

the ceramic fiber comprises oxides, nitrides or carbides of at least one selected among Si, Al, Ti, Zr, Ca and Mg.

3 . The coated fabric according to claim 2 , wherein:

the ceramic fiber comprises oxides of at least one selected among Si, Al, Ti, Zr, Ca and Mg.

4 . The coated fabric according to claim 3 , wherein:

the ceramic fiber comprises SiO 2 , CaO and MgO.

5 . The coated fabric according to claim 4 , wherein:

the ceramic fiber contains 50 to 60% by weight of SiO 2 , 20 to 30% by weight of CaO, and 10 to 30% by weight of MgO.

6 . The coated fabric according to claim 1 , wherein:

the binder resin comprises at least one selected among a urethane resin and a silicone resin.

7 . The coated fabric according to claim 1 , wherein:

the coating layer contains the filler in an amount of 20% by weight or less, based on 100% by weight of the entire coating layer.

8 . The coated fabric according to claim 1 , wherein:

the fibrous substrate comprises at least one selected among a polyester fiber, an aramid fiber, a nylon fiber, a carbon fiber, a polyketone fiber, a cellulose fiber, a polyolefin fiber, and an acrylic fiber.

9 . The coated fabric according to claim 8 , wherein:

the fiber contained in the fibrous substrate has a fineness in the range of 450 to 1,100 dtex.

10 . The coated fabric according to claim 8 , wherein:

the fibrous substrate is a fabric comprising warp and weft threads, and

the warp and weft densities of the fabric are within the range of 20 to 55 th/inch, respectively.

11 . The coated fabric according to claim 1 , wherein:

the coated fabric has a thickness of 0.25 to 0.40 mm.

12 . A method for preparing a coated fabric comprising:

coating a coating composition comprising a binder resin and a filler onto a fibrous substrate and then curing the coated composition to form a coating layer,

wherein the filler comprises agglomerates of chopped ceramic fibers having a size in the range of 0.1 to 2.0 mm,

wherein a coating amount of the coating layer to one layer of the fibrous substrate is 50 gsm to 100 gsm, and

wherein the coated fabric has a weight of 280 g/m 2 to 350 g/m 2 .

13 . An air bag comprising the coated fabric according to claim 1 .
