Footwear and Production Method Thereof

Abstract

A method of producing a foamed footwear includes the steps of wearing around a footwear last with an inner covering housing, coating a first partition layer made of mixed rubber material on an outer surface of the inner covering housing, covering on a foaming raw material and an outer decorating fabric, attaching to the bottom side of the footwear last with a footwear sole, attaching to an outer surface of the outer decorating fabric with necessary reinforcing elements and necessary decorating elements, and heating in a vulcanization reactor. The foaming raw material undergoes a foaming reaction process, so that the footwear sole, the necessary reinforcing elements, and the necessary decorating element undergo a vulcanizing reaction process to enhance rubber properties thereof. Both of the inner surface and outer surface of the footwear has an aesthetic appearance. The production efficiency is increased and unnecessary waste of raw material is avoid.

What is claimed is: 
     
         1 . A method of producing a footwear, comprising the steps of:
 (a) wearing around a footwear last with a stocking-shape inner covering housing made of inner lining fabric, in such a manner that said inner covering housing is fittingly attached to an outer surface of said footwear last;   (b) coating a first partition layer, made of mixed rubber material, on an outer surface of said inner covering housing;   (c) covering and attaching at least a foaming raw material, which have not been undergone a foaming process, to an outer surface and a bottom surface of said inner covering housing, wherein said first partition layer has a predetermined hardness and impermeability in comparison with said foaming raw material to be attached to said inner covering housing;   (d) covering and attaching at least an outer decorating fabric to an outer surface of said foaming raw material, wherein a bottom surface of said foaming raw material is not attached with said outer decorating fabric, wherein an inner surface of said outer decorating fabric is pre-coated with a second partition layer, made of mixed material containing rubber ingredient, wherein said second partition layer has a predetermined hardness and impermeability in comparison with said foaming raw material;   (e) attaching a footwear sole, one or more necessary reinforcing elements, and one or more necessary decorating elements, which are made of mixed material containing rubber ingredient before vulcanization reaction, to an outer surface of said outer decorative fabric to form a semi-finished footwear to form a semi-finished footwear; and   (f) undergoing said semi-finished footwear a foaming and vulcanizing reaction to enhance rubber properties of wherein said footwear sole, said necessary reinforcing elements, and said necessary decorating elements, wherein a foaming and expanding of said foaming material is restricted between said first partition layer on said outer surface of said inner covering housing and said second partition layer on said inner surface of said outer decorating fabric, and also is restricted between said footwear sole and said first partition layer on said outer surface of said inner covering housing, wherein said foaming raw material, said footwear sole, said necessary reinforcing elements, said necessary decorating elements, said inner covering housing, and said outer decorating fabric are integrated and fused with each other to produce a foamed footwear.   
     
     
         2 . The method, as recited in  claim 1 , wherein said first partition layer is pre-coated on said outer surface of said inner covering housing before said inner covering housing is worn around said footwear last. 
     
     
         3 . The method, as recited in  claim 1 , wherein said first partition layer is coated on a lateral side of a flat inner covering fabric, and then said flat inner covering fabric is sewed to form said stocking-shape inner covering housing, wherein said first partition layer is provided on said outer surface of said inner covering housing. 
     
     
         4 . The method, as recited in  claim 1 , wherein said outer decorating fabric is plastic fabric. 
     
     
         5 . The method, as recited in  claim 1 , wherein said outer decorating fabric is rubber fabric. 
     
     
         6 . The method, as recited in  claim 1 , wherein said outer decorating fabric is PU fabric. 
     
     
         7 . The method, as recited in  claim 1 , wherein said outer decorating fabric is natural leather without a second partition layer provided on an inner surface thereof. 
     
     
         8 . The method, as recited in  claim 1 , wherein said outer decorating fabric is artificial leather without a second partition layer provided on an inner surface thereof. 
     
     
         9 . The method, as recited in  claim 1 , wherein said outer decorating fabric is rubber leather without a second partition layer provided on an inner surface thereof. 
     
     
         10 . The method, as recited in  claim 2 , wherein said inner covering housing has a stretching ability, wherein said first partition layer also has a stretching flexibility and is stretched and shrunk together with said inner covering housing. 
     
     
         11 . The method, as recited in  claim 3 , wherein said inner covering housing has a stretching ability, wherein said first partition layer also has a stretching flexibility and is stretched and shrunk together with said inner covering housing. 
     
     
         12 . A footwear, comprising a footwear body and a footwear sole, wherein from outside to inside, said footwear body comprises at least a reinforcing element, at least a decorating element, at least an outer decorating fabric layer, a second partition layer, a foam layer, an inner covering housing, and a first partition layer, wherein said reinforcing element and said decorating element are bonded to an outer side of said outer decorating fabric layer, said second partition layer is provided on an inner surface of said outer decorating fabric layer, and said first partition layer is provide on an outer surface of said inner covering housing, wherein said footwear sole is provided at a bottom side of said footwear, wherein another foaming layer is formed between said footwear sole and said first partition layer on said outer surface of said inner covering housing. 
     
     
         13 . The footwear, as recited in  claim 12 , wherein said outer decorating fabric is plastic fabric. 
     
     
         14 . The footwear, as recited in  claim 12 , wherein said outer decorating fabric is rubber fabric. 
     
     
         15 . The footwear, as recited in  claim 12 , wherein said outer decorating fabric is PU fabric. 
     
     
         16 . The footwear, as recited in  claim 12 , wherein said outer decorating fabric is natural leather. 
     
     
         17 . The footwear, as recited in  claim 12 , wherein said outer decorating fabric is artificial leather.
