Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
169 words
A nonwoven fabric comprising a substantially isotropic web comprising at least 70% rayon staple fibers characterized by said web having regions wherein the fibers of the web have been lightly entangled by the action of columnar jets of fluid, and said web containing a small amount of adhesive binder substantially uniformly distributed throughout said web, the amount of binder being sufficient to resist wet collapse of said web, and said fabric having an excellent balance of wiping properties, abrasion resistance, and softness; said fabric comprising two series of fibrous bands that are substantially perpendicular to each other, wherein each band in both series contains segments in which the individual fibers are all substantially parallel to each other, which segments alternate with regions in which the fibers have been randomly entangled, said regions occurring where an individual band of one series intersects an individual band of the other series, and wherein at regularly spaced intervals between the individual bands of both of said series there are openings in said fabric.
Claim 2
Dependent Claim
169 words
A nonwoven fabric comprising a substantially isotropic web comprising at least 70% rayon staple fibers characterized by said web having regions wherein the fibers of the web have been lightly entangled by the action of columnar jets of fluid, and said web containing a small amount of adhesive binder substantially uniformly distributed throughout said web, the amount of binder being sufficient to resist wet collapse of said web, and said fabric having an excellent balance of wiping properties, abrasion resistance, and softness; said fabric comprising two series of fibrous bands that are substantially perpendicular to each other, wherein each band in both series contains segments in which the individual fibers are all substantially parallel to each other, which segments alternate with regions in which the fibers have been randomly entangled, said regions occurring where an individual band of one series intersects an individual band of the other series, and wherein at regularly spaced intervals between the individual bands of both of said series there are openings in said fabric.
Claim 3
Dependent Claim
17 words
The nonwoven fabric of claim 1, having regions about the openings, wherein the fibers are knotted together.
Claim 4
Dependent Claim
194 words
A nonwoven fabric comprising a substantially isotropic web comprising at least 70% rayon staple fibers characterized by said web having regions wherein the fibers of the web have been lightly entangled by the action of columnar jets of fluid and said web containing a small amount of adhesive binder substantially uniformly distributed throughout said web, the amount of binder being sufficient to resist wet collapse of said web, and said fabric having an excellent balance of wiping properties, abrasion resistance, and softness; said fabric comprising a series of parallel fibrous bands interconnected by a series of generally parallel sepentine fibrous bands, each such serpentine band curving according to the mirror image of its next adjacent band, wherein each band of both series contains segments in which lengths of the individual fibers are disposed in a linear or a curvilinear unentangled manner, which segments alternate with regions in which the fibers have been randomly entangled, said regions occurring where an individual band of one series intersects an individual band of the other series and wherein at regularly spaced intervals between the individual bands of both of said series there are rounded openings in said fabric.
Claim 5
Dependent Claim
194 words
A nonwoven fabric comprising a substantially isotropic web comprising at least 70% rayon staple fibers characterized by said web having regions wherein the fibers of the web have been lightly entangled by the action of columnar jets of fluid and said web containing a small amount of adhesive binder substantially uniformly distributed throughout said web, the amount of binder being sufficient to resist wet collapse of said web, and said fabric having an excellent balance of wiping properties, abrasion resistance, and softness; said fabric comprising a series of parallel fibrous bands interconnected by a series of generally parallel sepentine fibrous bands, each such serpentine band curving according to the mirror image of its next adjacent band, wherein each band of both series contains segments in which lengths of the individual fibers are disposed in a linear or a curvilinear unentangled manner, which segments alternate with regions in which the fibers have been randomly entangled, said regions occurring where an individual band of one series intersects an individual band of the other series and wherein at regularly spaced intervals between the individual bands of both of said series there are rounded openings in said fabric.
Claim 6
Dependent Claim
28 words
The fabric of claim 1 wherein the binder content is within the range of from about 0.8 to 10 weight percent, based on weight of fibers plus binder.
Claim 7
Dependent Claim
13 words
The fabric of claim 3 wherein the binder is an acrylic latex polymer.
