Abstract
Abstract A soft, absorbent nonwoven material useful as an all purpose wipe is disclosed. The material includes a three dimensional web of an open array of long fibers, a minor fraction of which have Z-direction orientation and regenerated cellulose fragments. The regenerated cellulose fragments are randomly dispersed throughout the web of fibers with the concentration of regenerated cellulose being greatest on and adjacent to the web surfaces and diminishing toward the web mid section. The fragments are adhered to the long fibers and, in combination with the Z-direction oriented fibers, unite the web into a coherent material.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
107 words
A soft, absorbent nonwoven material consisting essentially of a three dimensional web of an open array of long textile fibers, a fraction of which have substantial Z-direction orientation relative to the generally planar outer web surfaces and, based on the weight of the web, 10-50% regenerated cellulose, said regenerated cellulose being present as fragments randomly dispersed throughout the web with the concentration of regenerated cellulose being greatest on and adjacent to said outer web surfaces and of diminished concentration toward the web mid section, said fragments being adhered to said long fibers to, in combination with the Z-direction oriented fibers, unite the web into a coherent material.
Claim 2
Dependent Claim
107 words
A soft, absorbent nonwoven material consisting essentially of a three dimensional web of an open array of long textile fibers, a fraction of which have substantial Z-direction orientation relative to the generally planar outer web surfaces and, based on the weight of the web, 10-50% regenerated cellulose, said regenerated cellulose being present as fragments randomly dispersed throughout the web with the concentration of regenerated cellulose being greatest on and adjacent to said outer web surfaces and of diminished concentration toward the web mid section, said fragments being adhered to said long fibers to, in combination with the Z-direction oriented fibers, unite the web into a coherent material.
Claim 3
Dependent Claim
20 words
The material of claim 1 wherein the three dimensional web is an air laid web of substantially randomly deposited fibers.
Claim 4
Dependent Claim
13 words
The material of claim 2 wherein the air laid web is lightly pre-bonded.
Claim 5
Dependent Claim
12 words
The material of claim 2 wherein the air laid web is needled.
Claim 6
Dependent Claim
16 words
The material of claim 2 containing, based on the weight of the web, 25-40% regenerated cellulose.
Claim 7
Dependent Claim
20 words
The material of claim 5 wherein the air laid web has a basis weight of about 60-100 g./yd. 2 .
Claim 8
Dependent Claim
13 words
The material of claim 6 wherein the air laid web is lightly pre-bonded.
