Fabric bearing design and process for producing same

Abstract

Provided is a fabric having a novel design in which an uneven-surface design is partially formed by embossing. A polyurethane resin is applied to the surface of the fabric having, on the surface, a low fineness portion and a high fineness portion having a higher single fiber fineness than that of the low fineness portion, the fabric is dried; and embossing is performed on the surface of the fabric. By performing the embossing, while an uneven-surface design is not imparted to the high fineness portion by the embossing and a non-uneven-surface design portion 3 is formed, the uneven-surface design is imparted to the low fineness portion by the embossing and an uneven-surface design portion 2 is formed.

1 . A process for producing a fabric bearing a design partially having an uneven-surface design by embossing, the process comprising:
 applying a polyurethane resin to a surface of a fabric having, on the surface, a low fineness portion and a high fineness portion having a higher single fiber fineness than that of the low fineness portion;   drying the fabric; and   performing embossing on the surface of the fabric.   
     
     
         2 . The process for producing a fabric bearing a design according to  claim 1 ,
 wherein, by performing the embossing, while the uneven-surface design is not imparted to the high fineness portion by the embossing and a non-uneven-surface design portion is formed, the uneven-surface design is imparted to the low fineness portion by the embossing and an uneven-surface design portion is formed.   
     
     
         3 . The process for producing a fabric bearing a design according to  claim 1 ,
 wherein the low fineness portion includes threads having a single fiber fineness of 1.5 dtex or lower, and   the high fineness portion includes threads having a single fiber fineness of higher than 1.5 dtex.   
     
     
         4 . The process for producing a fabric bearing a design according to  claim 1 ,
 wherein the polyurethane resin is applied so that, in the low fineness portion, a permeation thickness of the polyurethane resin is 40 to 400 μm, a filling ratio of the polyurethane resin is 10% to 55%, and a filling ratio of fibers is 45% to 80%.   
     
     
         5 . The process for producing a fabric bearing a design according to  claim 1 ,
 wherein the polyurethane resin is applied so that a void ratio in the high fineness portion is 10% or higher and is higher than a void ratio in the low fineness portion.   
     
     
         6 . The process for producing a fabric bearing a design according to  claim 1 ,
 wherein the polyurethane resin is applied so that the polyurethane resin permeates between the fibers at least in a surface portion of the fabric and the surface of the fabric is formed by the polyurethane resin and the fibers.   
     
     
         7 . A fabric bearing a design comprising:
 a polyurethane resin which is present on a surface portion of the fabric; and   an uneven-surface design portion and a non-uneven-surface design portion on the surface portion,   wherein the uneven-surface design portion is constituted by threads having a lower single fiber fineness than that of the non-uneven-surface design portion, and an uneven-surface design is imparted to a surface of the uneven-surface design portion by embossing, and   the non-uneven-surface design portion is constituted by threads having a higher single fiber fineness than that of the uneven-surface design portion, and the uneven-surface design is not imparted to a surface of the non-uneven-surface design portion by the embossing.   
     
     
         8 . The fabric bearing a design according to  claim 7 ,
 wherein adjacent fibers in the uneven-surface design portion are fixed together more firmly than in the non-uneven-surface design portion by the polyurethane resin such that the uneven-surface design is imparted to the uneven-surface design portion by the embossing.   
     
     
         9 . The fabric bearing a design according to  claim 7 ,
 wherein the uneven-surface design portion includes threads having a single fiber fineness of 1.5 dtex or lower, and   the non-uneven-surface design portion includes threads having a single fiber fineness of higher than 1.5 dtex.   
     
     
         10 . The fabric bearing a design according to  claim 7 ,
 wherein, in the uneven-surface design portion, a permeation thickness of the polyurethane resin is 40 to 400 μm, a filling ratio of the polyurethane resin is 10% to 55%, and a filling ratio of the fibers is 45% to 80%.   
     
     
         11 . The fabric bearing a design according to  claim 7 ,
 wherein a void ratio in the non-uneven-surface design portion is 10% or higher and is higher than a void ratio in the uneven-surface design portion.   
     
     
         12 . The fabric bearing a design according to  claim 7 ,
 wherein the polyurethane resin permeates between the fibers at least in a surface portion of the fabric and a surface of the fabric is formed by the polyurethane resin and the fibers.   
     
     
         13 . The fabric bearing a design according to  claim 7 ,
 wherein a sum of outer circumferential lengths of fiber cross-sections in the uneven-surface design portion is 1500 μm or more per unit area 10,000 μm 2 .
