Fabric and method for manufacturing the same

Abstract

Provided is a fabric that has excellent stain resistance and excellent flame retardancy and that is less likely to generate water spots and is less likely to cause pieces thereof to attach to each other, and a method of manufacturing the fabric. The fabric according to the present invention is a polyester fabric impregnated with a fluorinated water-and-oil repellent agent and includes a coating layer on one surface thereof, the coating layer containing a fluorinated water-and-oil repellent agent, an organic phosphorus flame retardant having a solubility in water at 20° C. of 4% or less, and an acrylic resin having a glass-transition temperature of −43° C. to −20° C.

What is claimed is: 
     
         1 . A fabric being a polyester fabric impregnated with a fluorinated water-and-oil repellent agent, the fabric comprising a coating layer on one surface thereof,
 the coating layer containing a fluorinated water-and-oil repellent agent, an organic phosphorus flame retardant having a solubility in water at 20° C. of 4% or less, and an acrylic resin having a glass-transition temperature of −43° C. to −20° C.   
     
     
         2 . The fabric according to  claim 1 , wherein the coating layer is formed on a rear surface of the fabric. 
     
     
         3 . The fabric according to  claim 1 , wherein the coating layer further contains thermally expandable microcapsules that project from a surface of the coating layer to form projections and recesses. 
     
     
         4 . The fabric according to  claim 1 , wherein an amount, per unit area of the fabric, of the coating layer is 70 g/m 2  or less. 
     
     
         5 . A method of manufacturing a fabric, the method comprising the steps of:
 (a) immersing a polyester fabric in a treatment liquid containing a fluorinated water-and-oil repellent agent to make the fabric contain the treatment liquid, and then drying the fabric;   (b) subjecting the fabric to hot water cleaning at a temperature of 65 to 90° C. or reduction cleaning; and   (c) coating one surface of the fabric with a coating composition containing a fluorinated water-and-oil repellent agent, an organic phosphorus flame retardant having a solubility in water at 20° C. of 4% or less, and an acrylic resin having a glass-transition temperature of −43° C. to −20° C., to form a coating layer.   
     
     
         6 . The method according to  claim 5 , wherein the coating composition used in the step (C) further contains thermally expandable microcapsules, and
 the method comprises, after the step (C), a step of expanding the thermally expandable microcapsules contained in the composition by a heat treatment to project the thermally expandable microcapsules from a surface of the coating layer.   
     
     
         7 . The fabric according to  claim 2 , wherein the coating layer further contains thermally expandable microcapsules that project from a surface of the coating layer to form projections and recesses. 
     
     
         8 . The fabric according to  claim 2 , wherein an amount, per unit area of the fabric, of the coating layer is 70 g/m 2  or less. 
     
     
         9 . The fabric according to  claim 3 , wherein an amount, per unit area of the fabric, of the coating layer is 70 g/m 2  or less. 
     
     
         10 . The fabric according to  claim 7 , wherein an amount, per unit area of the fabric, of the coating layer is 70 g/m 2  or less.
