Definitions

• the present invention is directed to cut resistant gloves. More particularly, the present invention is directed to cut resistant gloves having a plaited construction.
• the present invention is directed to the second type of glove construction, i.e., plaited glove construction.
• Plaited gloves have been available to the market for many years. Their use has increased as manufacturers have been able to combine different components to get desired characteristics. For example, by utilizing a composite yarn on the outside and a stretchable yarn on the inside, manufacturers have been able to achieve good cut resistance in a stretchable and comfortable glove.
• a composite yarn is a core wrapped with various component yarns or several component yarns knit together, or several yarns that have been combined prior to being knit into a glove.
• Gloves have also been made with a non-elastic filament on the inside and stretchable elastic on the outside. This construction has been used to allow a darker color outside to hide dirt and to keep the clear or white filament on the inside.
• High tensile strength filament yarns tend to be white, cream or natural colored. If these yarns are made in a color, the process typically weakens the yarn. Adding dye to the liquid formula prior to extrusion may decrease the strength of the filament.
• the surface must be etched in order for the dye crystals to adhere to the filament. This etching weakens the yarn as well. Consequently, most plaited gloves involving filament yams utilize the dark colored plaiting yarn on the outside construction to hide the dirt.
• Cut resistant gloves are typically made, partially, with cut resistant filaments. All such gloves use an elastic fiber of one of various types to enable adequate stretching. Some glove fibers are plied in a method of stretching elastic fiber or fibers and then wrapping a cut-resistant filament around the elastic fiber or fibers, and adding a cross-wrap of, for example, nylon, to counter the torque.
• plaiting Another method of making a cut resistant glove made from a filament elastic is called plaiting (sometimes spelled "plating.”), as discussed above.
• plaiting it is not the yarn design that makes the glove elastic, but the knitting process.
• plaiting essentially, two gloves are knit together simultaneously. This allows for the outer surface of the glove to be made from one material and the inside to be of another. Plaiting became popular because one side of a glove could be made from an elastic material and the other side made from a cut resistant filament.
• One advantage of this design is that, on the filament side, pure filament could be used and the fibers of the filament could be parallel.
• Many gloves are made today with this construction, however, all such gloves have the filament on the inside and the elasticized nylon on the outside.
• U.S. Patent No. 7,669,442 is directed to a glove comprising three different types of yarns. These yarns include a cut resistant composite yarn, a companion yarn, and a liner yarn that are co-knit together with the lining yarn plated to the interior of the glove. The lining contacts the skin and separates the cut resistant yarn from the skin. The stated purpose is to prevent skin irritation from abraded fiberglass or other cut resistant fiber from contacting the skin.
• Zhu utilizes a core having at least two different core yarns and at least one wrapping yarn that is helically wrapped around the two combined core yarns.
• the companion yarn that is wrapped around the core yarns provides additional protection from irritation to the user by the cut resistant composite yarn and provides lubricity to the yarn bundle knitted in the glove.
• a cut resistant glove wherein the glove has an inner surface and an outer surface and wherein the inner surface is adapted for contacting a hand of a user, and the outer surface is visible while the user is wearing the glove.
• the glove includes a two layer knit fabric of a plaited construction including a first layer on the inner surface and a second layer on the outer surface.
• the outer surface is constructed from non-stretchable, cut resistant yarn, wherein the yarn has filaments that are generally parallel to one another and the inner surface is constructed from a stretchable, elastic yarn.
• the stretchable, elastic yarn may be of a color that contrasts with the a color of the non- stretchable, cut resistant yarn such that the elastic yarn becomes more visible during wear of the non-stretchable, cut resistant outer surface of the glove.
• the filaments of the non-stretchable, cut resistant yarn may include a dulling agent.
• FIG. 1 is a bottom view of a cut resistant glove having a plaited construction in accordance with a preferred embodiment of the present invention
• FIG. 2 is a front view of a portion of a plaited fabric as knitted in the cut resistant glove, having a plaited construction of FIG. 1 ;
• FIG. 3 is a cross-sectional view of the cut resistant glove having a plaited construction of FIG. 1, taken substantially along lines ⁇ - - ⁇ of FIG. 1.
• the present invention is directed to plaited gloves knit with non-stretchable filament yarn on the outside.
• the present invention utilizes the rolling action of the parallel filaments as its key component for cut resistance and wear. Wear becomes a necessary part of hand protection because as a glove surface wears down, its cut resistance is severely diminished.
• the non-elastic yarn By placing the non-elastic yarn on the outside of the glove, the most abrasion resistant component (the filament) is on the outside. Additionally, when the filament fibers of the cut resistant yarn are parallel to each other, they can roll on each other for increased cut resistance. An added benefit is that the parallel filaments are less likely to trap dirt and can be cleaned more easily in a laundering process. Non-elastic filament also increases the puncture resistance.
• the safety glove industry has always been concerned with wear factor of cut resistant gloves as safety personnel know that as a glove surface wears down, the cut resistance is diminished.
• a contrasting colored stretchable elastic on the inside of the glove, the user will be able to clearly see when the outside filament is wearing down and becoming less safe as the contrasting colored stretchable elastic begins to show through.
• a high- visibility nylon may be used on the inside of the glove in, for example, orange, yellow, lime green, or red, such that the user will be able to see the wear of the glove and know when it is no longer safe to wear.
• This has been a major issue with gloves in that the user does not easily know when the gloves are worn thin enough to become a hazard. It is of particular importance with plaited gloves, since they typically are thicker than standard elastic filament yarn gloves.
• the cut resistant yarn is pure filament, with fibers running parallel, and is non- stretchable in its yarn form.
• This yarn provides the highest tensile strength and the most abrasion resistance of any yarn construction.
• the resulting glove construction will have both stretch and loft. The stretch will come from the inside plaiting yarn and the loft will come from the double layer construction of the plaiting process.
• cut resistant yarn has filaments that also include a dulling agent in its construction, then all six of the industry's recognized components would be part of the glove of the present invention. Filament yarns with a dulling component added are available.
• the non- stretchable filament is knit loosely so that the stretchable yarn can pull it in.
• the stretchable yarn stretches and the filament moves to its original looser knit state in order to create a "give" in the fabric.
• the most abrasion resistant yarn i.e., the cut resistant filament, is on the outside for wear.
