Method for producing a reinforced polyester non-woven material

Abstract

A method for producing a reinforced polyester non-woven material suitable for use as a roofing material, comprising: forming a mixture comprising glass fibers and a liquid binder; applying the mixture to a polyester non-woven material; and curing the liquid binder to form a layer comprising glass fibers that is attached to the polyester non-woven material.

1 . A method for producing a reinforced polyester non-woven material suitable for use as a roofing material, comprising:
 forming a mixture comprising glass fibers and a liquid binder;   applying the mixture to a polyester non-woven material; and   curing the liquid binder to form a layer comprising glass fibers that is attached to the polyester non-woven material.   
   
   
       2 . The method of  claim 1 , wherein the mixture comprises the glass fibers dispersed in the liquid binder. 
   
   
       3 . The method of  claim 1 , wherein the mixture is applied to the polyester non-woven material such that a majority of the glass fibers are oriented in the plane of the polyester non-woven material. 
   
   
       4 . The method of  claim 1 , wherein the glass fibers are randomly oriented in the plane of the polyester non-woven material. 
   
   
       5 . The method of  claim 1 , wherein the polyester non-woven material has an elongated shape. 
   
   
       6 . The method of  claim 1 , further comprising conveying the polyester non-woven material, wherein the mixture is applied to the material while the material is being conveyed. 
   
   
       7 . The method of  claim 6 , wherein a suction apparatus is arranged underneath the polyester non-woven material to draw at least a part of the liquid binder into the polyester non-woven material. 
   
   
       8 . The method of  claim 1 , wherein the step of applying the mixture to the polyester non-woven material comprises conveying the polyester non-woven material through a receptacle containing the mixture. 
   
   
       9 . The method of  claim 8 , wherein the mixture is applied to the polyester non-woven material by partially or entirely immersing the polyester non-woven material into the mixture. 
   
   
       10 . The method of  claim 1 , wherein the binder comprises an acrylate, styrenebutadien, latex or mixtures thereof. 
   
   
       11 . The method of  claim 1 , further comprising curing the binder after the mixture is applied to the polyester non-woven material. 
   
   
       12 . The method of  claim 1 , wherein the glass fibers have an average diameter of from about 10 to about 20 microns. 
   
   
       13 . The method of  claim 1 , wherein the glass fibers are present in an amount of from about 10 to about 100 grams/m 2 , based on the surface area of the reinforced material. 
   
   
       14 . The method of  claim 1 , wherein the binder is present in an amount of from about 15 to about 40 grams/m 2 , based on the surface area of the reinforced material. 
   
   
       15 . A roofing material formed by the method according to  claim 1 .
