Fabric having uneven-surface design, and method for producing same

Abstract

Provided is a fabric to which an uneven-surface design which is fine and has flexibility and wear resistance is imparted. The fabric has a polyurethane resin applied portion on at least a portion of a surface side of the fabric, and an uneven-surface design shaped on the polyurethane resin applied portion. The polyurethane resin applied portion is a region in which a polyurethane resin which is applied is present, and the polyurethane resin permeates between the fibers at least in a surface portion of the fabric such that a surface of the fabric is formed by the polyurethane resin and the fibers. In the polyurethane resin applied portion, an application depth of the polyurethane resin is 50 to 200 μm, a filling ratio of the polyurethane resin is 15% to 45%, and a filling ratio of the fibers of the fabric is 50% to 80%.

1 . A fabric comprising:
 a polyurethane resin applied portion on at least a portion of a surface side of the fabric constituted by fibers; and   an uneven-surface design shaped on the polyurethane resin applied portion,   wherein the polyurethane resin applied portion is a region in which a polyurethane resin which is applied is present, and the polyurethane resin permeates between the fibers at least in a surface portion of the fabric such that a surface of the fabric is formed by the polyurethane resin and the fibers, and   in the polyurethane resin applied portion, an application depth of the polyurethane resin is 50 to 200 μm, a filling ratio of the polyurethane resin is 15% to 45%, and a filling ratio of the fibers is 50% to 80%.   
     
     
         2 . The fabric according to  claim 1 ,
 wherein a void ratio in the polyurethane resin applied portion is 13% or less.   
     
     
         3 . The fabric according to  claim 1 ,
 wherein the sum of outer circumferential lengths of fiber cross-sections in the polyurethane resin applied portion is 1500 μm or more per unit area 10,000 μm 2 .   
     
     
         4 . The fabric according to  claim 1 ,
 wherein the number of fibers per 100 μm 2  of the cross-sectional area of the polyurethane resin in the polyurethane resin applied portion is 1.5 or more.   
     
     
         5 . The fabric according to  claim 1 ,
 wherein, in the polyurethane resin applied portion, the application depth of the polyurethane resin is 50 to 100 μm, the filling ratio of the polyurethane resin is 20% to 35%, and the filling ratio of the fibers is 55% to 75%.   
     
     
         6 . The fabric according to  claim 1 ,
 wherein a ratio of the application depth of the polyurethane resin to a thickness of the fabric having the uneven-surface design is 3% to 30%.   
     
     
         7 . The fabric according to  claim 1 ,
 wherein a width of a recess forming the uneven-surface design is 200 to 1500 μm and a maximum depth of the recess is 20 to 450 μm.   
     
     
         8 . A method for producing a fabric, the method being a method for producing the fabric according to  claim 1 , the method comprising:
 applying a polyurethane resin to at least a portion of a surface side of the fabric and thereafter shaping the uneven-surface design on a polyurethane resin applied portion by embossing.   
     
     
         9 . The method for producing a fabric according to  claim 8 ,
 wherein the fabric as an object to which the polyurethane resin is applied is a woven fabric, and   in the woven fabric, in a region to which the uneven-surface design is imparted, a total fineness per unit volume 1 mm 3  is 2500 to 5800 dtex.   
     
     
         10 . The method for producing a fabric according to  claim 8 ,
 wherein the fabric as an object to which the polyurethane resin is applied is a knitted fabric, and   in the knitted fabric, in a region to which the uneven-surface design is imparted, a total fineness per unit volume 1 mm 3  is 1000 to 5800 dtex.
