Claim 3

The nonwoven fabric-like laminate of claim 1 wherein the nonwoven web has a basis weight of about 0.3-about 0.7 oz./yd.2, the thermoplastic polymer is polypropylene, and the filaments have a denier of about 0.8-about 2.5.

Claim 4

The nonwoven fabric-like laminate of claim 1 comprising outer plies of cellulose wadding and, as an inner ply, the single ply nonwoven web.

Claim 5

The nonwoven fabric-like laminate of claim 3 wherein the continuous filament web is bonded by the application of heat and pressure at intermittent areas occupying about 5-50% of the web area and in a density of about 50-3200 per square inch.

Claim 6

The nonwoven fabric-like laminate of claim 4 wherein the thermoplastic polymer is polypropylene.

Claim 7

The nonwoven fabric-like laminate of claim 3 wherein the nonwoven web has a basis weight of about 0.3-about 0.7 oz./yd.2, the thermoplastic polymer is polypropylene, and the filaments have a denier of about 0.8-about 2.5.

Claim 8

A nonwoven fabric-like laminate comprising, in combination, a. a low basis weight, single ply nonwoven web of subsTantially continuous and randomly deposited, molecularly oriented filaments of a hydrophobic thermoplastic polymer selected from polyolefins, polyurethanes, polyvinyls, polyamides and polyesters, said web prepared by continuous polymer extrusion through a spinneret and filament deposition on a supporting surface and having a basis weight of up to 0.7 oz./yd.2 with the filaments thereof having a denier of about 0.5-about 6, b. a web of cellulose wadding having a basis weight of about 0.3-about 0.7 oz./yd.2 disposed in laminar relationship with respect to the single ply web (a), and c. patterned areas of a plastisol adhesive disposed between said webs which penetrate into said cellulose wadding web at spaced open areas occupying less than about 25% surface area in a manner so as to provide delamination resistance in combination with fabric-like flexibility, said nonwoven web and cellulose wadding web combining to provide a material with desirable isotropic strength characteristics, fabric-like opaqueness, absorbency, and a natural fabric feel.

Claim 9

A nonwoven fabric-like laminate comprising, in combination, a. a low basis weight, single ply nonwoven web of subsTantially continuous and randomly deposited, molecularly oriented filaments of a hydrophobic thermoplastic polymer selected from polyolefins, polyurethanes, polyvinyls, polyamides and polyesters, said web prepared by continuous polymer extrusion through a spinneret and filament deposition on a supporting surface and having a basis weight of up to 0.7 oz./yd.2 with the filaments thereof having a denier of about 0.5-about 6, b. a web of cellulose wadding having a basis weight of about 0.3-about 0.7 oz./yd.2 disposed in laminar relationship with respect to the single ply web (a), and c. patterned areas of a plastisol adhesive disposed between said webs which penetrate into said cellulose wadding web at spaced open areas occupying less than about 25% surface area in a manner so as to provide delamination resistance in combination with fabric-like flexibility, said nonwoven web and cellulose wadding web combining to provide a material with desirable isotropic strength characteristics, fabric-like opaqueness, absorbency, and a natural fabric feel.

Claim 10

The nonwoven fabric-like laminate of claim 7 wherein the continuous filament web is bonded by the application of heat and pressure at intermittent areas occupying about 5-50% of the web area and in a density of about 50-3200 per square inch.

Claim 11

The nonwoven fabric-like laminate of claim 8 wherein the nonwoven web has a basis weight of about 0.3-about 0.7 oz./yd.2, thermoplastic polymer is polypropylene, and the filaments have a denier of about 0.8-about 2.5.

Claim 12

The nonwoven fabric-like laminate of claim 8 comprising outer plies of cellulose wadding and, as an inner ply, the single ply nonwoven web.

Claim 13

The nonwoven fabric-like laminate of claim 10 wherein the spaced open areas of plastisol adhesive occupy less than about 15% surface area.
