Environmentally friendly polymeric textile coating

Abstract

A composition comprises a polyvinylchloride homopolymer, a biodegradable plasticizer and either a swelling agent or a carbohydrate coupled to the polyvinylchloride homopolymer or a combination thereof. The composition may further comprise a blowing agent. A coated fabric comprises a textile substrate and a biodegradable coating at least partially coating the textile substrate, wherein the biodegradable coating degrades at least 60% after 28 days under the ASTM D584 standard. A method of making a biodegradable coating comprises providing a polymer and blending a biodegradable plasticizer with the polymer to form a blend. A method of making a coated textile comprises providing a textile and a composition comprising a polymer, a biodegradable plasticizer, and at least one other component; applying the composition to the textile; and curing the composition, thereby making a coated textile.

1 . A method of making a biodegradable coating for textile products comprising:
 providing a polyvinylchloride homopolymer;   blending a biodegradable plasticizer with the polyvinylchloride homopolymer to form a blend;   adding at least two other components to the blend from the group consisting of: a swelling agent, a blowing agent, and a carbohydrate;   wherein the biodegradable coating degrades at least 60% after 28 days under the ASTM D584 standard.   
     
     
         2 . The method of  claim 1  further comprising adding a catalyst to the blend. 
     
     
         3 . The method of  claim 1  further comprising adding a non-biodegradable plasticizer to the blend. 
     
     
         4 . The method of  claim 1  wherein one of the at least two components added to the blend is a carbohydrate, the method further comprising coupling the carbohydrate to the polyvinylchloride homopolymer. 
     
     
         5 . A method of making a biodegradable coating comprising:
 providing a polyvinylchloride homopolymer; and   blending a biodegradable plasticizer with the polyvinylchloride homopolymer to form a blend.   
     
     
         6 . The method of  claim 5  further comprising adding a blowing agent to the blend. 
     
     
         7 . The method of  claim 5  further comprising mechanically frothing the blend. 
     
     
         8 . The method of  claim 5  further comprising adding a swelling agent to the blend. 
     
     
         9 . The method of  claim 5  further comprising coupling a carbohydrate to the polyvinylchloride homopolymer. 
     
     
         10 . The method of  claim 8  further comprising coupling a carbohydrate to the polyvinylchloride homopolymer. 
     
     
         11 . The method of  claim 8  further comprising adding a blowing agent to the blend. 
     
     
         12 . The method of  claim 9  further comprising adding a blowing agent to the blend. 
     
     
         13 . The method of  claim 10  further comprising adding a blowing agent to the blend. 
     
     
         14 . The method of  claim 8  further comprising adding expandable or hollow microspheres. 
     
     
         15 . The method of  claim 9  further comprising adding expandable microspheres or hollow microspheres. 
     
     
         16 . A method of making a coated textile comprising:
 providing a textile having a plurality of fibers;   providing a composition comprising a polymer, a biodegradable plasticizer, and at least one other component;   applying the composition to the textile so that the composition at least partially coats some of the plurality of fibers of the textile such that the composition is either at least partially absorbed into the fibers or at least partially adhered onto the surface of the fibers; and   curing the composition, thereby making a coated textile.   
     
     
         17 . The method of  claim 16  wherein the at least one other component is selected from the group consisting of: a swelling agent, a blowing agent, and a carbohydrate. 
     
     
         18 . The method of  claim 16  wherein the polymer comprises polyvinylchloride homopolymer. 
     
     
         19 . The method of  claim 16  wherein the coated textile has a coefficient of friction of at least about 0.7. 
     
     
         20 . The method of  claim 16  further comprising metering the amount of the composition on the textile such that the thickness of the composition coating the textile ranges from about 20 mils to about 100 mils;
 wherein the polymer comprises polyvinylchloride homopolymer and the at least one other component is selected from the group consisting of: a swelling agent, a blowing agent, and a carbohydrate.
