a process for producing a cloth-like nonwoven web from thermoplastic polymer fibers; fiber adapted to produce wefts; nonwoven web and process for improving the thermal aging stability of a nonwoven web made of polymeric fibers.

摘要

Extruded fibers and nonwoven webs made from the fibers are disclosed having improved cloth-like properties and an improved aesthetic appearance. The fibers used to form the webs are made from a thermoplastic polymer containing titanium dioxide and at least one mineral filler such as kaolin or calcium carbonate. In particular, the fillers are added in the amount so that the fillers become encapsulated within the polymeric material.
