Title: Shoe pad assembly

Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to a shoe pad assembly. More particularly, the present invention relates to a shoe pad assembly which is used as an insole. 
     A conventional shoe pad is made in one piece. In general, the conventional shoe pad has poor air permeable effect and poor water absorbing effect. 
     SUMMARY OF THE INVENTION 
     An object of the present invention is to provide a shoe pad assembly which has a polyethylene terephthalate non-woven fabric layer to absorb water effectively. 
     Another object of the present invention is to provide a shoe pad assembly which has a gauze dipping in a solution containing activated carbon, alum, resin and ceramic powders producing far-infrared in order to form two web-shaped films on the gauze to become an air permeable layer. 
     Accordingly, a shoe pad assembly comprises a first layer, a second layer, a third layer, and an elastic base layer. The third layer is disposed on the elastic base layer. The second layer is disposed on the third layer. The first layer is disposed on the second layer. The first layer is an air permeable fabric. The second layer has two web-shaped films and a gauze disposed between the web-shaped films. The third layer is a water absorbing polyethylene terephthalate non-woven fabric layer.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to FIGS. 1 to  3 , a shoe pad assembly  1  comprises a first layer  11 , a second layer  12 , a third layer  13 , and an elastic base layer  14 . 
     The third layer  13  is disposed on the elastic base layer  14 . 
     The second layer  12  is disposed on the third layer  13 . 
     The first layer  11  is disposed on the second layer  12 . 
     The first layer  11  is an air permeable fabric. 
     The second layer  12  has a gauze  122  dipping in a solution containing activated carbon, alum, resin and ceramic powders producing far-infrared in order to form two web-shaped (non-woven) films  121  on the gauze  122  to become an air permeable layer. 
     The third layer  13  is a water absorbing polyethylene terephthalate (PET) non-woven fabric layer. 
     When the gauze  122  is dipped in a solution containing activated carbon, alum, resin and ceramic powders, the activated carbon, alum, resin and ceramic powders are adhered on the gauze  122 . After the gauze  122 , the activated carbon, the alum, the resin and the ceramic powders are dried, two web-shaped (non-woven) films  121  are formed on the gauze  122  so that the gauze  122  and the web-shaped (non-woven) films  121  become an air permeable layer. 
     The first layer  11 , the second layer  12 , the third layer  13 , and the elastic base layer  14  are preheated in a mold and impacted in the mold to form a product. 
     The present invention is not limited to the above embodiment but various modification thereof may be made. Furthermore, various changes in form and detail may be made without departing from the scope of the present invention.
