Method for manufacturing fabric

1. A method for manufacturing a fabric comprising the steps of:

(a) immersing a polyester fabric in a treatment liquid containing a first fluorine-based water-and-oil repellent agent to incorporate the treatment liquid thereinto, followed by drying the fabric;

(b) coating one surface of the fabric with a coating composition containing a second fluorine-based water-and-oil repellent agent and a flame retardant; and

(c) cleaning the fabric having the coating layer formed thereon with hot water of 65° C. to 90° C.

2. The method according to claim 1 , wherein the one surface of the fabric is a rear surface of the fabric.

3. The method according to claim 1 , wherein the coating of the step (b) is carried out so that

the second fluorine-based water-and-oil repellent agent content of the coating layer, per unit area of fabric, is in the range of 0.5 g/m 2 to 4.0 g/m 2 , and

the flame retardant content of the coating layer, per unit area of fabric, is in the range of 25 g/m 2 to 60 g/m 2 .

4. The method according to claim 1 , wherein the coating composition comprises a binder selected from an acrylic resin, a urethane resin, and a polyester resin, and coating of step (b) is carried out so that the binder content of the coating layer, per unit area of fabric, is in the range of 15 g/m 2 to 35 g/m 2 .

5. The method according to claim 1 , wherein the flame retardant is a phosphorus flame retardant having a solubility to water at 20° C. of 4.0% or less.

6. The method according to claim 1 , comprising a step of cleaning the fabric after the step (a) and before the step (b).

7. The method according to claim 1 , further comprising a step of bonding a foam sheet to the one surface of the fabric after the step (c).
