Abstract
Abstract The present invention involves an aqueous surface treatment agent for polymer fibers on the basis of a resin preparation, characterized in that it contains 1-30 percent by weight of a polar phenoplast of the resol type 2-40 percent by weight of a copolymer, crosslinkable with resols, of a radical polymerizable, aromatic hydroxymethyl and/or methyl halogen compound and water to make 100 percent by weight, wherein, if desired, up to 5 percent by weight further adhesion promoters can be present. This invention also involves the use of the surface treatment agent for the modification of organic or inorganic polymer fibers, preferably polyamide or polyimide fibers, particularly aromatic polyimide fibers, and a process for the modification of polymer fibers.
