Abstract
Abstract Woven, folded, reusable absorbent products such as diapers, panty pads, surgical dressings, general use sponges and pads, compresses, and the like, comprising a plurality of interior layers and outer layers, the interior layers comprising multiply, highly absorbent fabric layers, preferably of gauze, and the outer layers comprising single-ply, stronger, more abrasion resistant, longer-wearing, fabric layers, preferably of birdseye, all of the layers being integrally fabricated at the same time in a single weaving operation and subsequently folded, as desired or required. Methods of making such absorbent products are also involved.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
89 words
An integrally woven, folded, reusable absorbent product comprising a plurality of interior layers and outer layers, said interior layers comprising two-ply, highly absorbent fabric layers extending throughout the warpwise length of the product and said outer layers comprising single-ply, strong, abrasion resistant, long wearing fabric layers also extending throughout the warpwise extent of the product, each ply of said interior layers having substantially fewer warp yarns per inch than are present in said single ply and having half the number of filler picks per inch present in said single-ply.
Claim 2
Dependent Claim
89 words
An integrally woven, folded, reusable absorbent product comprising a plurality of interior layers and outer layers, said interior layers comprising two-ply, highly absorbent fabric layers extending throughout the warpwise length of the product and said outer layers comprising single-ply, strong, abrasion resistant, long wearing fabric layers also extending throughout the warpwise extent of the product, each ply of said interior layers having substantially fewer warp yarns per inch than are present in said single ply and having half the number of filler picks per inch present in said single-ply.
Claim 3
Dependent Claim
90 words
An integrally woven, folded, reusable absorbent product comprising a plurality of interior layers and outer layers, said interior layers comprising two-ply highly absorbent gauze fabric layers extending throughout the warpwise length of the product and said outer layers comprising single-ply, strong abrasion-resistant, long wearing birdseye fabric layers also extending throughout the warpwise extent of the product, each ply of said interior layers having substantially fewer warp yarns per inch than are present in said single ply and having half the number of filler picks per inch present in said single-ply.
Claim 4
Dependent Claim
90 words
An integrally woven, folded, reusable absorbent product comprising a plurality of interior layers and outer layers, said interior layers comprising two-ply highly absorbent gauze fabric layers extending throughout the warpwise length of the product and said outer layers comprising single-ply, strong abrasion-resistant, long wearing birdseye fabric layers also extending throughout the warpwise extent of the product, each ply of said interior layers having substantially fewer warp yarns per inch than are present in said single ply and having half the number of filler picks per inch present in said single-ply.
Claim 5
Dependent Claim
35 words
A woven, folded, reusable absorbent product as defined in Claim 2 wherein the product comprises a central panel and two side panels and the gauze fabric layers are located substantially completely within the central panel.
Claim 6
Dependent Claim
17 words
A woven, folded, reusable absorbent product as defined in Claim 2 wherein there are two gauze layers.
Claim 7
Dependent Claim
17 words
A woven, folded, reusable absorbent product as defined in Claim 2 wherein there are four gauze layers.
Claim 8
Dependent Claim
17 words
A woven, folded, reusable absorbent product as defined in Claim 2 wherein there are six gauze layers.
Claim 9
Independent Claim
115 words
A method of making folded, reusable absorbent products possessing excellent absorbency, along with excellent strength, excellent abrasion resistance, and long wearing properties which comprises: forming a continuous fabric in a single weaving operation in which the fabric has, in side-by-side relation, at least one single-ply section having from 80-140 warp ends per inch and at least one double-ply section having from 40-70 warp ends per inch, the two sections having a common filler of from 25-70 picks per inch; separating said fabric along its length into blanks for the product; and then folding said blanks in such a way that the product is formed wherein double-ply fabric is covered on opposite sides by single-ply fabric.
Claim 10
Independent Claim
115 words
A method of making folded, reusable absorbent products possessing excellent absorbency, along with excellent strength, excellent abrasion resistance, and long wearing properties which comprises: forming a continuous fabric in a single weaving operation in which the fabric has, in side-by-side relation, at least one single-ply section having from 80-140 warp ends per inch and at least one double-ply section having from 40-70 warp ends per inch, the two sections having a common filler of from 25-70 picks per inch; separating said fabric along its length into blanks for the product; and then folding said blanks in such a way that the product is formed wherein double-ply fabric is covered on opposite sides by single-ply fabric.
Claim 11
Dependent Claim
34 words
The method according to claim 7 wherein the ratio of the number of warp ends per inch in the single-ply section to the number of warp ends in the double-ply section is about eight-thirds.
Claim 12
Dependent Claim
26 words
The method according to claim 8 wherein the fabric is formed with three sections, a centrally extending single-ply section bounded on opposite sides by double-ply sections.
Claim 13
Dependent Claim
26 words
The method according to claim 8 whereiN the fabric is formed with three sections, a centrally extending double-ply section bounded on opposite sides by single-ply sections.
Claim 14
Dependent Claim
24 words
The method according to claim 8 wherein the fabric is provided along its length with transverse picking bars along which the blanks are separated.
