Abstract
Abstract An embossed nonwoven fabric having a textured character and fabriclike qualities of softness and hand and suitable for wiping surfaces having aqueous and/or oleaginous liquids and/or more viscous semisolids thereon comprising a web containing at least one layer of overlapping, intersecting fibers, a pattern of intermittantly spaced, embossed, compacted or densified fibrous areas lying in the planes of both surfaces of said web of overlapping, intersection fibers, and a pattern of unembossed, uncompacted fibrous portions lying between said planes and connecting said embossed, compacted fibrous areas.

Claim 10
Dependent Claim
86 words
An embossed nonwoven fabric having a textured character and fabriclike qualities of softness and hand and suitable for wiping surfaces having aqueous or oleaginous liquids or more viscous semisolids thereon comprising a carded fibrous web containing at least one layer of overlapping, intersecting fibers, a pattern of intermittently spaced, embossed compacted fibrous areas lying in the planes of both surfaces of said web of overlapping, intersecting fibers, and a pattern of unembossed, uncompacted fibrous portions lying between said planes and connecting said embossed, compacted fibrous areas.
Claim 11
Dependent Claim
88 words
An embossed nonwoven fabric having a textured character and fabriclike qualities of softness and hand and suitable for wiping surfaces having aqueous or oleaginous liquids or more viscous semisolids thereon comprising a fibrous web containing at least one layer of overlapping, intersecting fibers, a pattern of intermittently spaced, embossed compacted fibrous areas lying in the planes of both surfaces of said web of overlapping, intersecting fibers, and a pattern of Unembossed, uncompacted fibrous portions lying between said planes and slantingly and angularly connecting said embossed, compacted fibrous areas.
Claim 12
Dependent Claim
101 words
An embossed nonwoven fabric having a textured character and fabriclike qualities of softness and hand and suitable for wiping surfaces having aqueous or oleaginous liquids or more viscous semisolids thereon comprising a fibrous web containing at least one layer of overlapping, intersecting fibers, a pattern of intermittently spaced, embossed compacted fibrous areas lying in the planes of both surfaces of said web of overlapping, intersecting fibers, said planes being substantially parallel but offset with respect to each other, and a pattern of unembossed, uncompacted fibrous portions lying between said substantially parallel but offset planes and connecting said embossed, compacted fibrous areas.
Claim 13
Dependent Claim
122 words
An embossed nonwoven fabric having a textured character and fabriclike qualities of softness and hand and suitable for wiping surfaces having aqueous or oleaginous liquids or more viscous semisolids thereon comprising a fibrous web containing at least one layer of overlapping, intersecting fibers, said layer being so embossed that a portion of one surface thereof lies in one plane and a portion of its other surface lies in a substantially parallel but offset plane with respect to the first plane, a pattern of intermittently spaced, embossed compacted fibrous areas lying in the planes of both surfaces of said web of overlapping, intersecting fibers, and a pattern of unembossed, uncompacted fibrous portions lying between said planes and connecting said embossed, compacted fibrous areas.
