Abstract
Flexible coated bundles of fibers are provided that are both encapsulated and impregnated with a coating of one or more independently partially crosslinkable polyurethane. The fibers in the bundle can have a first chemical treatment or size and the bundle of these fibers is treated to have the coating of the polyurethane. The coating impregnates the bundle so that a majority of the fibers have a substantial portion of their surfaces covered with the coating. The independently partially crosslinkable polyurethane is selected from polyurethane polymers that are solvent-soluble, dispersible or emulsifiable that produce a thermoplastic elastomeric film. The partial crosslinkability is from one or more of the following types of crosslinking: self-crosslinkable, internally crosslinkable and/or in-situ crosslinkable. Additional components other than external crosslinking agents can also be present in the coating composition.
