Abstract
A protective garment 10, such as a glove, arm guard or the like of wire 24 and fiber strands 26, 28, 30 and an elastomeric coating 16. The preferred garment is knitted from yarn 12 having a core 22 of one or more wire strands 24 and a fiber strand 26, and two wrappings of fiber strands 28, 30, preferably polyester. The knitted garment is coated, preferably by dipping in nitrile rubber, and the coating is cured in place. The garment is highly cut-resistant, nonabsorbent, highly slip-resistant, liquid in weight and flexible.
Claims30
A protective glove comprised of a cover having wire strands, and a fabric liner, and a continuous coating of elastomeric material permeating the cover and adhering the liner and cover together, the improvement wherein the cover is knit from yarn comprised of a core having 2 to 6 strands of stainless steel wire and a parallel synthetic polymer fiber strand having a denier ob 800 to 1500, the overall diameter of the wire strands being no greater than 0.020 inch, and strands, all of which are nonaramid fiber, having a denier of 210 to 630, wrapped about the core in opposite directions one on top of the other, the total diameter of the yarn being no greater than 0.050 inch.
A protective glove of knitted yarn covered with a coating of elastomeric material cured in place and having a fabric liner bonded in place with the coating, the improvement wherein said yarn has a core comprised of four strands of stainless steel wire about 0.003 inch in diameter and a parallel strand of synthetic polymer fiber having a denier of 800 to 1500, the overall diameter of said core wire being no greater than 0.020 inch and said yarn has wrapping strands, all of which are nonaramid fiber having a denier of 210 to 630 wrapped about the core in opposite directions one on top of the other, at least the outer strand of which is polyester, the total diameter of the yarn being no greater than about 0.050 inch, said glove being highly cut-resistant, nonabsorbent to dirt, fat, blood and the like, with high slip resistance and good feel to the wearer, and light in weight, stretchable and flexible.
A protective garment, shaped to cover the extremity of a limb, comprised of a cover having wire strands, a fabric liner, and a continuous coating of elastomeric material permeating the cover and adhering the liner and cover together, the improvement wherein the cover is knit from yarn comprised of a core having 2 to 6 strands of stainless steel wire and a parallel synthetic polymer fiber strand having a denier of 800 to 1500, the overall diameter of the wire strands being no greater than 0.020 inch, and strands, all of which are nonaramid fiber, having a denier of 210 to 630, wrapped about the core in opposite directions one on top of the other, the total diameter of the yarn being no greater than 0.050 inch.
A flexible protective garment, shaped to cover the extremity of a limb, comprised of a fabric liner, a cover having wire strands over the liner, and a coating of elastomeric material permeating the cover and adhering the liner and cover together, the improvement wherein the cover is a garment shell knit from yarn comprised of a core having at least one strand of stainless steel wire 0.001 to 0.01 inch in diameter and a synthetic polymer fiber strand, and strands, all of which are nonaramid fiber, wrapped about the core in opposite directions one on top of the other.
A protective glove comprised of an inner glove-shaped fabric, a metal-wire-containing over-lay on the fabric and an elastomeric coating covering the overlay and bonding it to the fabric, the improvement wherein the overlay is knitted of yarn having a core of at least one wire strand and one fiber strand;
- and wrappings, all of which are nonaramid fiber, about the core, one on top of the other, the outer of which adheres strongly to the coating;
- said glove being flexible and highly cut resistant.
A protective material comprising:
- a base layer of textile material;
- an intermediate layer of relatively cut-resistant, fiber material formed from intermeshing strands, defining pores therebetween,
- an outer layer of solid, elastomeric material which retards penetration by liquid;
- said pores in said intermediate layer being sufficiently large to permit the passage therethrough of said elastomeric material when the latter is in a liquid state;
- said base layer being sufficiently non-porous to prevent the passage entirely therethrough of said elastomeric material when the latter is in a liquid state;
- said solid, elastomeric material extending through said intermediate layer, filling the pores in said intermediate layer and substantially totally encapsulating the strands of said intermediate layer;
- the bond between the base layer and the intermediate layer consisting essentially of said elastomeric material.
A method for producing an article composed of protective material comprising a base layer of textile material, an intermediate layer of relatively cut-resistant fiber material and an outer layer of solid, elastomeric material which retards penetration by liquid, said method comprising the steps of:
- providing said base layer in the form of textile material which is sufficiently nonporous to prevent the passage entirely therethrough of said elastomeric material when the latter is in a liquid state and which will bond to the elastomeric material;
- conforming said base layer to a predetermined shape dictated by the shape of said article;
- providing said intermediate layer in a form having intermeshing strands defining pores therebetween sufficiently large to permit the passage therethrough of said elastomeric material when the latter is in a liquid state;
- mounting said intermediate layer exteriorly to said base layer to conform the shape of said intermediate layer to the shape of the underlying base layer;
- providing said elastomeric material in a liquid state;
- dipping the base layer and mounted intermediate layer into said elastomeric material;
- said dipping step comprising flowing said liquid elastomeric material through said pores in said intermediate layer to cover said base layer, fill said pores and substantially totally encapsulate said strands with said elastomeric material;
- solidifying the liquid, elastomeric material and bonding it to said base layer while the elastomeric material covers the base layer, fills the pores in said intermediate layer and substantially totally encapsulates the strands in the intermediate layer;
- the bonding between said intermediate layer and said base layer consisting essentially of said elastomeric material.
