Abstract

Abstract of the Invention A strong, absorbent, abrasion-resis-tant, bonded nonwoven fabric compri-sing a fibrous layer of: (1) from 0% by weight to about 75% by weight of textile length staple fibers; and (2) from 100% by weight to about 25%
by weight of short fibers having a length less than the textile length staple fibers, the fibrous layer being bonded by: (1) primary, intermit-tently-spaced print pattern binder sites extending substantially from one surface of the fibrous layer to the other surface of the fibrous layer; and (2) secondary, intermit-tently-spaced, print pattern binder sites positioned predominantly on the surface of the fibrous layer and located thereon between the intermittently-spaced binder sites of the primary print pattern binder.

Claims (11)

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:-
1. A strong, absorbent, abrasion-resistant, bonded nonwoven fabric comprising a fibrous layer containing staple length textile fibers and short fibers having less than textile staple length wherein the staple length fibers comprise up to 75% by weight of the fiber weight of the fibrous layer and the balance of the fiber weight in said layer is provided by the less than textile staple length fibers said fibrous layer being bonded by: (1) primary, intermittently-spaced, print pattern binder sites extending substantially from one surface of said fibrous layer to the other surface of said fibrous layer, said primary binder sites being spaced apart a distance less than the average length of staple length textile fibers but greater than the average length of short textile fibers, and (2) secondary, intermittently-spaced print pattern binder sites positioned predominantly on the surface of said fibrous layer and located between the intermittently-spaced binder sites of primary print pattern binder.
2. A strong, absorbent, abrasion-resistant, bonded non-woven fabric as defined in claim 1 wherein the add-on of the primary binder is in the range of from about 6 by weight to about 30% by weight on a dry weight basis, based on the dry weight of the bonded nonwoven fabric.
3. A strong, absorbent, abrasion-resistant, bonded non-woven fabric as defined in claim l wherein the add-on of the secondary binder for each surface bonded thereby is in the range of from about 2 by weight to about 10% by weight on a dry weight basis, based on the dry weight of the bonded non-woven fabric.
4. A strong, absorbent, abrasion resistant, bonded non-woven fabric as defined in claim 1 wherein the short fibers are wood pump fibers.
5. A strong, absorbent, abrasion resistant, bonded non-woven fabric as defined in claim 1 wherein the short fibers are cotton linters.
6. A strong, absorbent, abrasion-resistant bonded non-woven fabric as defined in claim 1 wherein the textile length staple fibers are nylon fibers.
7. A strong, absorbent, abrasion-resistant bonded non-woven fabric as defined in claim 1 wherein the textile length staple fibers are polyester fibers.
8. A strong, absorbent, abrasion-resistant bonded non-woven fabric as defined in claim 1 wherein the textile length staple fibers are rayon.
9. A method of making a strong, absorbent, abrasion-resistant, bonded nonwoven fabric comprising: forming a fibrous layer from staple length textile fibers and short fibers having less than textile staple length to provide a fibrous layer wherein the staple length fibers comprise up to 75% by weight of the fiber weight of the fibrous layer and the balance of fiber weight in said layer is provided by the less than tex-tile staple length fibers, and bonding said fibrous layer with (1) primary, intermittently-spaced, print pattern binder sites extending substantially from one surface of said fibrous layer to the other surface of said fibrous layer, said primary binder sites being spaced apart a distance less than the aver-age length of staple length textile fibers but greater than the average length of short textile fibers; and (2) secondary, intermittently-spaced, print pattern binder sites positioned predominantly on the surface of said fibrous layer and located between the intermittently-spaced binder sites of said primary print pattern binder.
10, A method of making a strong, absorbent, abrasion-resistant, bonded nonwoven fabric as defined in claim 9 wherein the application of the primary bonding and the two secondary bondings takes place in three separate steps.
11. A method of making a strong, absorbent, abrasion-resistant, bonded nonwoven fabric as defined in claim 9 wherein the application of the primary bonding and one secondary bonding takes place on one surface of said bonded nonwoven fabric in one step and the application of the second secondary bonding takes place on the other surface of said bonded nonwoven fabric in a second step.
