Abstract
Provided among other things is a cut-resistant article comprising: a cut-resistant synthetic fabric; and adherent to the fabric a layer of polyurethane polymer in which is dispersed mineral fibers of hardness about 4 Mohs or higher and having L/D ratio between about 8 and about 16, wherein the article has a cut resistance by ISO 13997:1999 of 2 or higher.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A cut-resistant article comprising:
a fabric; and adherent to the fabric a layer of polyurethane polymer in which is dispersed mineral fibers of hardness about 4 Mohs or higher and having L/D ratio between about 8 and about 16, wherein the article has a cut resistance by EN388 of 2 or higher.
2 . The cut-resistant article of claim 1 , wherein the particles have average D mass weighted from about 5 to about 23 micron.
3 . The cut-resistant article of claim 2 , wherein the particles have average L mass weighted from about 100 to about 210 micron.
4 . The cut-resistant article of claim 2 , wherein the particles have average L mass weighted from about 100 to about 170 micron.
5 . The cut-resistant article of claim 2 , wherein the particles have hardness of about 5 Mohs or higher.
6 . The cut-resistant article of claim 1 , wherein the particles have hardness of about 5 Mohs or higher.
7 . The cut-resistant article of claim 1 , wherein the fabric is a cut-resistant synthetic fabric.
8 . A cut-resistant article comprising:
a cut-resistant synthetic fabric that is a 70% or more polyamide; and adherent to the fabric a layer of polyurethane polymer comprising about 5% or more polyurethane and about 60% or more nitrile in which is dispersed mineral fibers of hardness about 4 Mohs or higher and having L/D ratio between about 8 and about 27, wherein the article has a cut resistance by EN388 of 2 or higher, and wherein the polymer is adhered to the fabric by coagulation-mediated dip coating onto the fabric, and subsequent curing.
9 . The cut-resistant article of claim 8 , wherein the particles have average D mass weighted from about 5 to about 23 micron.
10 . The cut-resistant article of claim 9 , wherein the particles have average L mass weighted from about 100 to about 210 micron.
11 . The cut-resistant article of claim 9 , wherein the particles have average L mass weighted from about 100 to about 170 micron.
12 . The cut-resistant article of claim 9 , wherein the particles have hardness of about 5 Mohs or higher.
13 . The cut-resistant article of claim 8 , wherein the particles have hardness of about 5 Mohs or higher.
14 . A method of forming a cut-resistant article comprising:
applying a coagulant to a fabric; coagulating on the fabric a layer of polyurethane polymer in which is dispersed mineral fibers of hardness about 4 Mohs or higher and having L/D ratio between about 8 and about 27; curing the coagulated polymer; and obtaining the article, which has a cut resistance by EN388 of 2 or higher.
15 . The method of claim 14 , wherein the particles have average D mass weighted from about 5 to about 23 micron.
16 . The method of claim 14 , wherein the particles have average L mass weighted from about 100 to about 210 micron.
17 . The method of claim 16 , wherein the particles have hardness of about 5 Mohs or higher.
18 . The method of claim 14 , wherein the fabric is a cut-resistant synthetic fabric.
19 . A cut-resistant article comprising:
a fabric; and adherent to the fabric a layer of polyurethane polymer in which is dispersed mineral fibers of hardness about 4 Mohs or higher and having L/D ratio between about 8 and about 27, wherein the article has a cut resistance by EN388 of 2 or higher, wherein the article has one or more features indicative of layer of polymer being applied by a process wherein coagulant is applied to the cut-resistant synthetic fabric to coagulate a coagulation-sensitive dispersion of polymer to form the layer of polymer.
20 . The cut-resistant article of claim 19 , wherein the particles have average D mass weighted from about 5 to about 23 micron.Join the waitlist — get patent alerts
