ABSTRACT:
A shaped polyolefin structure, such as a polyolefin fiber or a nonwoven web containing polyolefin fibers, is rendered hydrophilic by contacting the structure with a gaseous mixture of chlorine, sulfur dioxide, and oxygen or carbon monoxide or a mixture thereof, in the presence of a free radical-producing means. Such treatment results in the formation of hydrogen sulfato groups at the structure surface. Preferably, the hydrogen sulfato groups are converted to ammonium sulfato groups by subsequent treatment with ammonia or a sufficiently basic amine.
