ABSTRACT:
This invention relates to the irradiation of compositions comprising non-ethylenically unsaturated brominated and chlorinated aromatic polyester fibrous materials with low intensity ultraviolet light radiation for relatively brief periods of time under appropriate conditions to yield a product of enhanced solvent resistance. The irradiation of the halogenated polyesters (as defined) generates free radicals within the fibrous material which react to produce sufficient cross-linking to enhance solvent resistance without a significant detrimental change of other product properties.
