Increased tear strength nonwoven fabric and process for its manufacture

摘要

A spun-bonded nonwoven composite web has randomly laid continuous matrix filaments (average linear density per filament less than 25 denier) and one or more continuous reinforcement filament (average linear density per filament which exceeds 20 denier and exceeds the average linear density per filament of said matrix filaments by at least 10 denier). The continuous matrix filaments are at least partially bonded together to form the web. The one or more continuous reinforcement filament is enmeshed in the web without substantially bonding to other filaments in the web, so as to exhibit pulled fiber behavior when the web is born.
