Method of making a moisture-permeable and waterproof shoe

Abstract

A method of making a moisture-permeable and waterproof shoe includes: forming a vamp and a bottom liner from a fabric laminate and connecting the vamp and the bottom liner to form a semi-finished shoe with seams; disposing a shoe last in a foot-receiving space provided in the semi-finished shoe; coating an outer surface of the semi-finished shoe with a resin material and curing the resin material to form a moisture-permeable and waterproof resin layer on the outer surface of the semi-finished shoe and to cover the seams; attaching a shoe sole to the bottom liner; and removing the shoe last from the receiving space.

What is claimed is: 
     
         1 . A method of making a moisture-permeable and waterproof shoe, comprising:
 forming a vamp and a bottom liner from a fabric laminate and connecting the vamp and the bottom liner to form a semi-finished shoe with seams;   disposing a shoe last in a foot-receiving space provided in the semi-finished shoe;   coating an outer surface of the semi-finished shoe with a resin material and curing the resin material to form a moisture-permeable and waterproof resin layer on the outer surface of the semi-finished shoe and to cover the seams;   attaching a shoe sole to the bottom liner; and   removing the shoe last from the receiving space.   
     
     
         2 . The method of  claim 1 , wherein prior to curing of the resin material, the shoe last is rotated to evenly distribute the resin material on the outer surface of the semi-finished shoe. 
     
     
         3 . The method of  claim 1 , wherein coating the outer surface of the semi-finished shoe with the resin material is performed by immersing the semi-finished shoe together with the shoe last in a resin material bath. 
     
     
         4 . The method of  claim 1 , wherein the fabric laminate includes an outer fabric layer and an inner fabric layer connected to the outer fabric layer. 
     
     
         5 . The method of  claim 4 , wherein the fabric laminate further includes a foam layer interposed between the outer fabric layer and the inner fabric layer. 
     
     
         6 . The method of  claim 4 , wherein an outer surface of the outer fabric layer is patterned. 
     
     
         7 . The method of  claim 4 , wherein an outer surface of the outer fabric layer is embossed. 
     
     
         8 . The method of  claim 1 , wherein the resin layer has a water resistance greater than 2000 mm as measured by the method in accordance with JIS L-1092B. 
     
     
         9 . The method of  claim 1 , wherein the resin layer has a moisture permeability greater than 2000 g/m 2 /24 hr as measured by the method in accordance with JIS L-1099B1. 
     
     
         10 . The method of  claim 1 , wherein the resin material is made from polyurethane resin. 
     
     
         11 . The method of  claim 1 , wherein the resin layer has an outer surface that is opposite to the outer fabric layer and that exhibits a glossy appearance. 
     
     
         12 . The method of  claim 1 , wherein the resin layer has an outer surface that is opposite to the outer fabric layer and that exhibits a matte appearance.
