Abstract
Abstract A method of making a low cost, nonwoven reinforced fabric laminate comprising two layers of lightly entangled fibers having binder at the jet surface thereof, and having a reinforcing layer therebetween, comprising superimposing the two fibrous layers and the scrim with the non-binder side of the fibrous layers next to the scrim and securing the reinforcing layer to each of the fibrous layers.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
184 words
A method of making a low cost, nonwoven, reinforced fabric laminate having excellent abrasion resistance, dimensional stability and absorbenty comprising the steps of: (a) lightly entangling a web of fibers utilizing high speed essentially columnar jets of fluid to form a first fibrous layer having a jet side and another side; (b) applying binder to the jet side of the first fibrous layer to surface bond the jet side only predominantly on the surface thereof; (c) superimposing a reinforcing layer upon the other side of said first fibrous layer; (d) lightly entangling a web of fibers utilizing high speed essentially columnar jets of fluid to form a second fibrous layer having a jet side and another side; (e) applying binder to the jet side of a second fibrous layer to surface bond the jet side only predominantly on the surface thereof; (f) superimposing said second fibrous layer upon said first fibrous layer and reinforcing layer, with the other side of said second fibrous layer next adjacent the reinforcing layer; and (g) securing said reinforcing layer to each of said first and second fibrous layers.
Claim 2
Independent Claim
184 words
A method of making a low cost, nonwoven, reinforced fabric laminate having excellent abrasion resistance, dimensional stability and absorbenty comprising the steps of: (a) lightly entangling a web of fibers utilizing high speed essentially columnar jets of fluid to form a first fibrous layer having a jet side and another side; (b) applying binder to the jet side of the first fibrous layer to surface bond the jet side only predominantly on the surface thereof; (c) superimposing a reinforcing layer upon the other side of said first fibrous layer; (d) lightly entangling a web of fibers utilizing high speed essentially columnar jets of fluid to form a second fibrous layer having a jet side and another side; (e) applying binder to the jet side of a second fibrous layer to surface bond the jet side only predominantly on the surface thereof; (f) superimposing said second fibrous layer upon said first fibrous layer and reinforcing layer, with the other side of said second fibrous layer next adjacent the reinforcing layer; and (g) securing said reinforcing layer to each of said first and second fibrous layers.
Claim 3
Dependent Claim
16 words
The method of claim 1 wherein said fibers comprise both absorbent fibers and high strength fibers.
Claim 4
Dependent Claim
26 words
The method of claim 1 further comprising the step of drying the binder prior to superimposing the first and second fibrous layer and the reinforcing layer.
Claim 5
Dependent Claim
26 words
The method of claim 1 wherein said reinforcing layer is thermoplastic and is secured to said first and second fibrous layers by the use of heat.
Claim 6
Dependent Claim
12 words
The method of claim 1 wherein said reinforcing layer comprises a scrim.
Claim 7
Dependent Claim
30 words
The method of claim 2 wherein said absorbent fibers are cotton and/or rayon, andsaid high strength fibers are selected from the group consisting of polyester, polyolefin, acrylic or nylon fibers.
Claim 8
Independent Claim
140 words
A method of making a low cost, nonwoven, reinforced fabric laminate having excellent abrasion resistance, dimensional stability and absorbency comprising the steps of: lightly entangling two separate webs of fibers utilizing high speed essentially columnar jets of fluid to form first and second separate fibrous layers, each having a jet side and a belt side, superimposing said first and second fibrous layers and a reinforcing layer with the belt side of the first and second fibrous layers next adjacent the reinforcing layer, and then, in either order, securing the reinforcing layer to the first and second fibrous layers, and applying binder to the jet side of the first and second fibrous layers now forming the outer surface of the fabric laminate to surface bond the jet sides only of said fibrous layers predominantly on the surface of said jet sides.
Claim 9
Independent Claim
140 words
A method of making a low cost, nonwoven, reinforced fabric laminate having excellent abrasion resistance, dimensional stability and absorbency comprising the steps of: lightly entangling two separate webs of fibers utilizing high speed essentially columnar jets of fluid to form first and second separate fibrous layers, each having a jet side and a belt side, superimposing said first and second fibrous layers and a reinforcing layer with the belt side of the first and second fibrous layers next adjacent the reinforcing layer, and then, in either order, securing the reinforcing layer to the first and second fibrous layers, and applying binder to the jet side of the first and second fibrous layers now forming the outer surface of the fabric laminate to surface bond the jet sides only of said fibrous layers predominantly on the surface of said jet sides.
Claim 10
Dependent Claim
19 words
A nonwoven reinforced wipe having excellent abrasion resistance and absorbency made by the method of claims 1 or 7.
