Abstract

See full text

A nonwoven web material including fibers formed of a polyolefin and a polyester is disclosed. The fibers may include fine fibers produced by, for example, a meltblowing process. The polyolefin may be polypropylene and the polyester may be polylactic acid. The polylactic acid may be obtained and included by recycling scrap nonwoven material containing a polylactic acid component, hydrolyzing the polylactic acid component to reduce its viscosity, blending the hydrolyzed polylactic acid with a polyolefin resin, and melt-spinning the blended material to form fibers. A related process is disclosed.
