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.

Description

BACKGROUND OF THE DISCLOSUREField of the Disclosure[0001]The present invention relates to a functional fabric and a method of manufacturing the fabric. More specifically, the present invention relates to a fabric that has stain resistance and flame retardancy and that is less likely to generate water spots and cause pieces thereof to attach to each other, and a method of manufacturing the fabric.Description of the Related Art[0002]A fabric used for interior of, for example, cars, ships, and airplanes (for example, a fabric used for a seat of vehicles such as a car and for trim members such as a door lining) is required to have flame retardancy as well as high stain resistance because it is difficult to wash or clean such a fabric.[0003]Known as a stain resistant treatment is water-and-oil repellent coating on a surface of a fabric, and known as a flame retardant treatment is flame retardant coating on a rear surface of a fabric.[0004]JP-A-2017-196831 discloses a fabric at least to a...

AI Technical Summary

Benefits of technology

[0006]An object of the present invention is to solve the above problems and to provide 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.

[0009]Coating a fabric with a coating composition containing a flame retardant is capable of imparting flame retardant performance to the fabric, whereas the fabric is likely to generate a problem that the fabric is easily discolored by, for example, hot water or water spilled thereon and the fabric does not return to the original color even when dried (that is, the fabric is likely to generate water spots). In the present invention, however, an organic phosphorus flame retardant having a low solubility in water is used as the flame retardant to be capable of providing a fabric less likely to generate water spots.

[0010]Coating a fabric with a coating composition containing a water-and-oil repellent agent does not allow the coating composition to sufficiently infiltrate the fabric, causing a tendency to increase the thickness of a coating layer on a surface of the fabric. Therefore, when 10 to 20 pieces of the fabric are stacked and cut, the pieces of the fabric are attached to each other to be likely to generate a problem of having trouble peeling the pieces of the fabric after cutting. In the present invention, however, an acrylic resin having a glass-transition temperature of −43° C. to −20° C. is used as the binder resin to be capable of providing a fabric less likely to generate attachment between pieces of the fabric even at the time of processing the stacked pieces of the fabric.

[0011]Further, the coating layer preferably contains thermally expandable microcapsules that project from a surface of the coating layer to form projections and recesses (concavoconvex shape). Formation of the projections and recesses on the surface of the coating layer of the fabric reduces contact area between pieces of the fabric even when a plurality of pieces of the fabric are stacked, so that the pieces of the fabric are more easily separated from each other.

[0013]With the amount of the coating layer set at 70 g / m2 or less, the attachment property between pieces of the fabric is reduced to allow the pieces to be more easily separated from each other.

[0020]According to the present invention, it is possible to provide a fabric that has high flame retardancy and stain resistance and that is less likely to generate water spots and cause pieces thereof to attach to each other, and a method of manufacturing the fabric.

Problems solved by technology

Coating a fabric with a coating composition containing a flame retardant is capable of imparting flame retardant performance to the fabric, whereas the fabric is likely to generate a problem that the fabric is easily discolored by, for example, hot water or water spilled thereon and the fabric does not return to the original color even when dried (that is, the fabric is likely to generate water spots).
