A method for Coating of a Hydrophobic Polymer Fibers with Poly (Vinyl alcohol) and coated Fibers composed of a Hydrophobic Polymer, they understand the method.

摘要

A method of coating of a Hydrophobic Polymer Fibers with Poly (Vinyl alcohol), whose method involves providing polu00edmerohidrofobico Fibres,Prepare a solution of Poly (Vinyl alcohol) in waterAnd try polu00edmerohid rofobico Fibers with the solution of Poly (alcoholvinu00edlico) under conditions sufficient to deposit the Poly (Vinyl alcohol) on the surfaces of the Fibers.In some embodiments, the polymer is fibrasde Hydrophobic polyolefin Fibers. For example, the polyolefin Fibres are Fibres of polypropylene or polyethylene.The COP (Vinyl alcohol) is the one which is generally referred to as Poly (Vinyl alcohol) soluble in hot water.Such material is altamentehidrolizado, has a degree of hydrolysis of around 98%. The Molecular Weight of Poly (Vinyl alcohol) will typically of around 10.000, which corresponds approximately to a degree of polymerization of 200.This Invention also provides a method for coating a depolu00edmero Hydrophobic Fibers with Poly (Vinyl alcohol).The Method involves providing Hydrophobic Polymer Fibers.Dissolve Poly (Vinyl alcohol) or at a temperature of at least ededor ALR 60 * c to obtain a solution of Poly (Vinyl alcohol)And Treating the polymer Fibers hidrofobicocon solution of Poly (Vinyl alcohol) under conditions sufficient to deposit the Poly (Vinyl alcohol) on the surfaces of the Fibers.Hydrophobic Polymer Fibers can be lasfibras polyolefin such as polyethylene or polypropylene Fibers.
