Liquid proof gloves having impact protection
A liquid proof glove having impact protection comprises an outer glove portion comprising an outer fabric layer having an inner surface and an outer surface, a polymeric coating adhered to the outer surface of the outer fabric layer, and at least one protective structure adhered to at least one of the polymeric coating or outer fabric layer, or both. The glove further comprises an inner glove portion comprising an inner fabric layer having an outer surface and an inner surface and a liquid proof barrier layer adhered to the outer surface of the inner fabric layer. The liquid proof barrier layer is adhered to the inner surface of the outer fabric layer to join the inner glove portion to the outer glove portion.
1. A supported glove comprising:
an outer glove portion comprising an outer fabric layer having an inner surface and an outer surface, a polymeric coating adhered to the outer surface of the outer fabric layer, and at least one protective structure adhered to at least one of the polymeric coating or outer fabric layer, or both; and
an inner glove portion comprising an inner fabric layer having an outer surface and an inner surface and a liquid proof, non-breathable barrier layer, comprised of at least one of thermoplastic urethane (TPU) or polyurethane (PU) having thermal adhesive on opposite sides of the liquid proof barrier layer, adhered to the outer surface of the inner fabric layer, wherein the liquid proof barrier layer is impermeable to liquids, and
wherein the liquid proof barrier layer is adhered to the inner surface of the outer fabric layer to join the inner glove portion to the outer glove portion.
2. The supported glove of claim 1 , wherein the inner fabric layer consists essentially of cotton.
3. The supported glove of claim 1 , wherein the polymeric coating has a rough surface texture.
4. The supported glove of claim 1 , wherein the polymeric coating comprises a first nitrile material, and wherein the polymeric coating covers a surface of a palm of the glove.
5. The supported glove of claim 1 , wherein a surface of a palm provides at least one of CE EN388:2016 level 4 puncture resistance, CE EN388:2016 level 4 abrasion resistance or NSI/ISEA105:2016: level A6 cut resistance.
6. The supported glove of claim 1 , wherein the at least one protective structure has a thickness between about 2 mm to about 5 mm above metacarpal bones, a thickness of about 6 mm above knuckles, fingers and thumb, and a softness of about 30 duro shore A to about 40 duro shore A.
7. The supported glove of claim 6 , wherein the at least one protective structure is flexible and includes regions which have less or no material.
8. The supported glove of claim 1 , wherein the outer fabric layer comprises:
a high performance poly ethylene (HPPE); and at least one of
glass fiber over the entire hand to impart cut resistance, or
a conductive material in at least a region corresponding to tips of at least one of the fingers or the thumb.
9. The supported glove of claim 1 , wherein the at least one outer protective structure extends on a dorsal side of the glove and extends along a thumb pocket or finger pocket of the glove, wherein the thumb or finger pocket extends longitudinally from a proximal end to a distal end along a longitudinal axis and each outer protective structure has a first portion and a second portion located proximally with respect to the first portion, the first portion having a width measured transverse to the longitudinal axis that is greater than a width of the second portion, and wherein the first portion covers the distal end of the thumb pocket or the finger pocket.
10. The supported glove of claim 9 , wherein the second portion extends from the first portion.
11. The supported glove of claim 1 , wherein the at least one protective structure is flexible and has at least one groove extending longitudinally and in a transverse direction.
12. A method of fabricating a glove, the method comprising:
providing an outer glove portion, the outer glove portion comprising an outer fabric layer having an inner surface and an outer surface, a polymeric coating adhered to the outer surface of the outer fabric layer, and at least one protective structure adhered to at least one of the polymeric coating or outer fabric layer, or both;
providing an inner glove portion, the inner glove portion comprising an inner fabric layer having an outer surface and an inner surface, and a liquid proof barrier layer, comprised of at least one of thermoplastic urethane (TPU) or polyurethane (PU) having thermal adhesive on opposite sides of the liquid proof barrier layer, in contact with the outer surface of the inner fabric layer
placing the liquid proof barrier layer of the inner glove portion in contact with the inner surface of the outer glove portion; and
heating the outer glove portion and the inner glove portion to heat and melt the thermal adhesive and bond the inner glove portion to the outer glove portion to form the glove and render the liquid proof barrier layer non-breathable.
13. The method of claim 12 , wherein the outer fabric layer of the outer glove portion is bonded to a first side of the liquid proof barrier, and wherein the inner fabric layer of the inner glove portion is bonded to a second side of the liquid proof barrier, the second side opposite the first side.
14. The method of claim 12 , further comprising placing the inner glove portion and the outer glove portion over a former comprising heating elements, wherein, the heating is provided via the heating elements.
15. The method of claim 14 , wherein the outer glove portion is placed on the former in a reversed configuration, the at least one protective structure in direct contact with the former, wherein the liquid proof barrier layer is placed over the reversed outer glove portion, and wherein the inner fabric layer is placed over the liquid proof barrier layer.
16. The method of claim 14 , wherein the inner fabric layer is placed on the former with the inner surface of the inner fabric layer in direct contact with the former, wherein the liquid proof barrier is placed over and in contact with the outer surface of the inner fabric layer, and wherein the outer glove portion is placed over the liquid proof barrier layer with the inner surface of the outer fabric layer in direct contact with the liquid proof barrier layer.
17. The method of claim 12 , wherein the inner fabric layer consists essentially of cotton, the outer fabric layer comprises a high performance poly ethylene (HPPE), optionally, glass fiber over the entire hand to impart cut resistance, and optionally, a conductive material in a region corresponding to tips of at least one of the fingers or the thumb, and wherein the liquid proof barrier layer comprises thermoplastic urethane (TPU).
18. The supported glove of claim 12 , wherein the at least one outer protective structure extends on a dorsal side of the glove and extends along a thumb pocket or finger pocket of the glove, wherein the thumb or finger pocket extends longitudinally from a proximal end to a distal end along a longitudinal axis and each outer protective structure has a first portion and a second portion located proximally with respect to the first portion, the first portion having a width measured transverse to the longitudinal axis that is greater than a width of the second portion, and wherein the first portion covers the distal end of the thumb pocket or the finger pocket.
19. The supported glove of claim 12 , wherein the at least one protective structure is flexible and has at least one groove extending longitudinally and in a transverse direction.
