Abstract

Elastic fibers are described that comprise (i) a polyolefin polymer, e.g., a homogeneously branched, preferably substantially linear, ethylene polymer, and (ii) a photoinitiator, e.g., an aromatic ketone, in an amount sufficient to effect at least a partial cross-linking of the polymer when the fiber is exposed to sufficient UV-radiation to activate the photoinitiator. Articles, e.g., fabrics, comprising fibers of this invention, either alone or in combination with one or more other fibers, e.g., cellulose, nylon, etc., exhibit good heat resistance and elasticity at elevated temperatures.
