Abstract
Method for modifying the surface properties of synthetic polymer fibers by coating the fibers with ultrathin organic monolayer films according to the Langmuir-Blodgett coating technique. The inventive method substantially reduces the amount of coating necessary to modify the surface properties of such fibers compared to conventional finishing techniques.

A method for modifying an uncoated synthetic polymer fiber comprising applying a Langmuir-Blodgett film coating consisting of a water-insoluble amphiphilic polymer, said water-insoluble polymer selected from the group consisting of poly(2-oxazolines) and poly(N-acylethyleneimines), to an uncoated synthetic polymer fiber by passing said fiber through a water-insoluble Langmuir-Blodgett film material that is positioned on a surface of water such that a monomolecular layer film coating of said Langmuir-Blodgett film material is deposited on a surface of said fiber by said passing step.
