Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
189 words
A method of simultaneously strengthening and decorating a low integrity dry-formed nonwoven fibrous web, said method comprising the steps of: a. forming spaced-apart densified regions in the web to strengthen the web by embossing a front surface of the web with spaced-apart raised surfaces of an embossing roll, the densified regions being able to transmit a treating fluid completely through the thickness of the web from a rear surface of the web to the front surface thereof, and simultaneous with the embossing; b. applying a treating fluid that includes a coloring agent to the rear surface of the web from a treating fluid conveying surface that is free of raised, spaced-apart web embossing areas for causing the fluid to be transmitted completely through the thickness of the web from the rear surface to the front surface thereof in substantially only the densified regions to thereby impart a valley print decorative effect in the front surface, the treating fluid conveying surface being disposed opposite the raised surfaces on the embossing roll and constituting a backing surface for the web during the step of forming the densified regions in said web.
Claim 2
Independent Claim

A method of simultaneously strengthening and decorating a low integrity dry-formed nonwoven fibrous web, said method comprising the steps of: a. forming spaced-apart densified regions in the web to strengthen the web by embossing a front surface of the web with spaced-apart raised surfaces of an embossing roll, the densified regions being able to transmit a treating fluid completely through the thickness of the web from a rear surface of the web to the front surface thereof, and simultaneous with the embossing; b. applying a treating fluid that includes a coloring agent to the rear surface of the web from a treating fluid conveying surface that is free of raised, spaced-apart web embossing areas for causing the fluid to be transmitted completely through the thickness of the web from the rear surface to the front surface thereof in substantially only the densified regions to thereby impart a valley print decorative effect in the front surface, the treating fluid conveying surface being disposed opposite the raised surfaces on the embossing roll and constituting a backing surface for the web during the step of forming the densified regions in said web.
Claim 3
Dependent Claim
13 words
The method according to claim 1, wherein the treating fluid includes a binder.
Claim 4
Dependent Claim
12 words
The dry-formed fibrous web made according to the method of claim 1.
Claim 5
Dependent Claim
47 words
The method according to claim 1, wherein the treating fluid conveying surface comprises the peripheral surface of a gravure roll, the gravure roll surface having a uniform distribution of fluid receiving cells therein for applying the treating fluid substantially uniformly over the rear surface of the web.
Claim 6
Dependent Claim
12 words
The dry-formed fibrous web made according to the method of claim 4.
Claim 7
Dependent Claim
64 words
The method according to claim 1, wherein the treating fluid includes a binder and the densified regions are distributed along the planar extent of the web and spaced-apart less than the average fiber length of the fibers forming the web so that fibers in the front surface of the web are bonded together to enhance the strength and abrasion resistance of the front surface.
Claim 8
Dependent Claim
12 words
The dry-formed fibrous web made according to the method of claim 6.
Claim 9
Dependent Claim
44 words
The method according to claim 1, wherein the treating fluid conveying surface comprises the peripheral surface of a gravure roll, the gravure roll surface including closely spaced fluid-receiving cells arranged in a pattern corresponding to a pattern of raised surfaces on the embossing roll.
Claim 10
Dependent Claim
13 words
The method according to claim 8, wherein the treating fluid includes a binder.
