Abstract
There is disclosed a net finishing process and composition for treating a net, such as a fishing net formed of synthetic material, to form a flexible film thereon. The net finishing composition is comprised of a low molecular weight, high acetate content, vinyl chloride-vinyl acetate copolymer resin, a monomeric plasticizer and a polymeric plasticizer dissolved in a solvent system.
Claims14
A concentrate solution for preparing a net finishing solution for treating a net substrate to improve the physical properties thereof which comprises:
- a solution of a low molecular weight, high acetate content, vinyl chloride-vinyl acetate copolymer;
- a monomeric plasticizer and a polymeric plasticizer in a solvent system, said copolymer having a molecular weight of from 20,000 to 65,000 and having an acetate content of from about 10 to about 20 percent by weight, said monomeric and polymeric plasticizers being present in an amount of from about 40 to 60 parts per 100 parts of said copolymer, the ratio of said monomeric plasticizer to said polymeric plasticizer being in the range of from 1:1 to 3:1, said solvent system being present in an amount to effect a solids content of said concentrate solution of between about 45 to 55 percent by weight.
A net finishing solution for treating a net substrate formed of a synthetic material to improve the physical properties thereof which comprises:
- a low molecular weight, high acetate content, vinyl chloride-vinyl acetate copolymer;
- a monomeric plasticizer and a polymeric plasticizer in a solvent system, said copolymer having a molecular weight of from 20,000 to 65,000 and having an acetate content of from about 10 to about 20 percent by weight, said monomeric and polymeric plasticizers being present in an amount of from about 40 to 60 parts per 100 parts of said copolymer, the ratio of said monomeric plasticizer to said polymeric plasticizer being in the range of from 1:1 to 3:1, said solvent system being present in an amount to provide a solids content of from 20 to about 40 percent by weight of the net finishing solution.
A process for treating a net substrate formed of a synthetic material to improve the physical properties thereof, which comprises:
- (a) coating said net substrate with a net finishing solution comprised of a low molecular weight, high acetate content vinyl chloride-vinyl acetate copolymer, a monomeric plasticizer and a polymeric plasticizer in a solvent system, said copolymer having a molecular weight of from 20,000 to 65,000 and having an acetate content of from about 10 to about 20 percent by weight, said monomeric and polymeric plasticizers being present in an amount of from about 40 to 60 parts per 100 parts of said copolymer, the ratio of said monomeric plasticizer to said polymeric plasticizer being in range of from 1:1 to 3:1, said solvent system including ketones and being present in an amount to result in a solids content of from 20 to 40 percent by weight of said net finishing solutions;
- and
- (b) drying said coated net substrate.
