Method for Coating Hydrophobic Polymer Fibers with Poly (Vinyl alcohol)

摘要

Which includes: (a) provide Hydrophobic Polymer Fibers.Preferred polyolefin fibers such as polypropylene and polyethylene Fibers; (b) a Poly (Vinyl alcohol) dissolved in water at a temperature of around 60 degrees to obtain a Solution DAnd poly (Vinyl alcohol), soluble in water, with a degree of hydrolysis of at least 98% and a Molecular Weight of at least 10 000,Which corresponds to a degree of polymerization of 200; and (c) to treat Hydrophobic Polymer Fibers with Poly (Vinyl alcohol) Solution under conditions sufficient to deposit Poly (Lcohol Vinyl) on the surface of Fibers
