ABSTRACT:
A method is provided giving a bundle of glass fiber strands improved integrity. A plurality of glass fiber strands are contacted with a fine, particlized, thermoplastic material in an amount up to about 0.5% by weight of the dried combined plurality of glass fiber strands in a forced gas chamber. The plurality of glass fiber strands containing the thermoplastic material is heated so that the thermoplastic material is softened on the plurality of strands thereby holding the strands together in such a manner that the plurality of strands can be processed without separating, but when the plurality of strands are chopped or woven the strands separate.
