ABSTRACT:
A method for improving the dyeing characteristics of textile materials containing polyolefin fibers is provided wherein the polyolefin fibers are coated with a coating composition consisting essentially of a film forming component containing at least one quaternary ammonium group. A preferred coating composition useful in the practice of the invention further includes a wetting agent and a minor effective amount of a fluorocarbon surfactant. Procedure for forming such coating compositions, application of same to polyolefin fibers, as well as dyeing of the coated polyolefin fibers is disclosed.
In one embodiment the film forming component is the reaction product of a chemical substance containing at least one quaternary ammonium group and at least two amino groups having active hydrogen and a polyepoxide having at least two 1,2-epoxy groups per molecule. A method for producing such a film forming component and application of same to a textile material containing polyolefin fibers is also set forth.
