Disfigure-resistant plastic-string mat

Abstract

A disfigure-resistant plastic-string mat includes a scraping layer and a lattice-shaped layer fused under the scraping layer. The scraping layer is made of plastic elastic strings formed randomly and irregularly into piled up countless rings interlocking an intercrossing with one another to define countless gaps. The lattice-shaped net layer is woven of fiber of high strength and fused with the scraping layer by means of immersion in plastic solution homogeneous with the scraping layer under high temperature, and firmly combined with the scraping layer after cooled so that the scraping layer may not easily shrink or lengthen, constricted by the lattice-shaped net layer.

What is claimed is:  
     
         1 . A disfigure-resistant plastic-string mat comprising: 
 A scraping layer made of countess number of plastic elastic strings formed to pile up randomly and irregularly as countless rings interlocking and intercrossing with one another, said strings forming countless gaps among them; and,    A lattice-shaped net layer weaved with fiber of high strength and low tensibility and fused under said scraping layer, said lattice-shaped net layer fused with said scraping layer by means of immersing in plastic solution homogeneous with said scraping layer under high temperature, said lattice-shaped layer firmly combined with said scraping layer after cooled in wake of said immersion.    
     
     
         2 . The disfigure-resistant plastic-string mat as claimed in  claim 1 , wherein said fiber is PET of low tensibility.  
     
     
         3 . The disfigure-resistant plastic-string mat as claimed in  claim 1 , wherein said lattice-shaped net layer has counter tensibility in the scope of 500-10,000 N/m.  
     
     
         4 . The disfigure-resistant plastic-string mat as claimed in  claim 1 , wherein a cushion layer is further added under said lattice-shaped layer.
