Patent ID: 8241743

Claim:
A nonwoven web having a machine direction and a cross direction, said nonwoven web comprising: (a) non-thermoplastic fibers comprising from about 20% to about 80% by weight of the nonwoven web of man-made fibers and from about 20% to about 80% by weight of the nonwoven web of pulp fibers, wherein at least about 20% by weight of said man-made fibers have a fiber length of at least about 18 mm; (b) a plurality of discrete compressed sites, each compressed site having selective breaking or weakening of fibers along edges of the compressed sites, the compressed sites are: i. less than about 2.5 square millimeters in area; and ii. separated by an edge to edge distance of no more than about 10 millimeters from the nearest adjacent discrete compressed site; (c) lines of weakness; and (d) discrete uncompressed regions, wherein said discrete uncompressed regions have an elongation at maximum force in the machine direction and an elongation at maximum force in the cross direction; wherein said (b) plurality of discrete compressed sites form said (c) lines of weakness and said (c) lines of weakness are arranged to substantially bound and define said (d) discrete uncompressed regions, such that when said web is subjected to a force less than the maximum force of said (d) discrete uncompressed regions in at least one of said machine direction or said cross direction, said web at least partially fails in tension along said (c) lines of weakness when the nonwoven web is flushed into a plumbing system.
