WO 2013/123038 PCT/US2013/025922 SEAMLESS RIDGE REINFORCED GLOVE BACKGROUND Field of the invention [0001] Embodiments of the present invention generally relate to gloves and, more particularly, to a seamless glove comprising reinforced ridges for external force, impact, and vibration dissipation and abrasion- and cut-resistance. Methods of making the glove are disclosed. Description of the Related Art [0003] Gloves are used in many industries and households to protect the hands of users. Many gloves are designed with specific applications in mind. For example, gloves may be specified for comfort, flexibility, dexterity as well as for high impact, shock absorption, durability, abrasion, and cut-resistance. However, many of such gloves are difficult to manufacture and require additional materials and manufacturing processes. Also, gloves cannot typically offer a balance of the foregoing properties. Therefore, there is a need in the art for a seamless, impact dampening, and/or cut-resistant glove having excellent grip properties that is flexible, comfortable, and easy to manufacture. SUMMARY OF THE INVENTION [0004] Seamless knitted gloves that includes at least one knitted ridge, substantially as shown in and/or described in connection with at least one of the figures, as set forth more completely in the claims, are disclosed. Methods for forming gloves are also disclosed. Various advantages, aspects, and novel features of the present disclosure, as well as details of an exemplary embodiment thereof, will be more fully understood from the following description and drawings. BRIEF DESCRIPTION OF THE DRAWINGS [0005] So that the manner in which the above recited features of the present invention can be understood in detail, a more particular description of the invention, 1 WO 2013/123038 PCT/US2013/025922 briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings. It is to be noted, however, that the drawings illustrate only some embodiments of this invention and are not to be considered limiting of its scope, for the invention admits to other equally effective embodiments.

A liner may be knitted by conventional knitting process and comprise various yarns, deniers, and gauges. A knitted glove comprises a main yarn and optionally a second ridge yarn knitted therewith. The ridge yarn may comprise polyester, nylon, SPANDEX@, LYCRATM, NOMEX@, TWARON@, KEVLAR@, DYNEEMA®, SPECTRA@, steel wire, natural rubber, fiberglass, carbon, shear thickening fluids, and the like or any blend of the fibers and materials. Gloves in accordance with embodiments of the invention may be knitted using automatic seamless glove knitting machines, such as, but not limited to, NSFG, SFG-1, and SWG by Shima Seiki Mfg., Ltd. [0017] Figure 1 depicts the palm side of a liner according to embodiments of the invention. Liner 100 comprises thumb 102, index finger 104, middle finger 106, ring finger 108, and pinky finger 110, upper palm 112, lower palm 114, and cuff 116. Liner 100 may comprise several ridges 101 on lower palm 114, upper palm 112, or fingers 104, 106, 108, 110, and thumb 102. Liner 100 may comprise several different designs for glove size, the amount and placement of ridges, and/or ridge dimensions. Ridges 101 are chosen for selective reinforcement in various areas of liner 100 and may be defined by their height H as projecting from the surface of liner 100, width W, and spacing S between ridges. [0018] In FIG. 1, for example and not by limitation, upper palm 112 has four sets of ridges 101 and index finger 104 has seven sets of ridges 101. In some embodiments, the height of ridges 101 on the fingers may range from essentially flush (such as 0.1mm) with the surface of the main yarn of the liner 100 to 1mm in height. Spacing S may be approximately as little as 0.2 mm to 2mm and Width W may be approximately 3mm. Upper palm 112 of glove 100 may comprise ridges 3mm in width W, 2mm in spacing S, and height H between 0-1mm. Ridges 101 are typically disposed perpendicular to the longitudinal axis of the liner for increasing the 3 WO 2013/123038 PCT/US2013/025922 grip properties of the glove, particularly on the palm side of the liner. Alternatively, ridges 101 may be disposed differently, such as parallel to the longitudinal axis, for other applications. In some embodiments of the present invention, some regions of the glove have ridges disposed both parallel and perpendicular to the longitudinal axis of the glove. [0019] Gloves in accordance with embodiments of the invention may further comprise indicia of the properties of the glove, based on the amount, and/or dimensions, of the ridges. For example, gloves may be indicated for certain duties, which can be characterized as light, medium, or heavy duty. A glove of the foregoing design will have maximum flexibility and very good grip, abrasion, durability, and impact resistance properties and could be considered for light duty for many applications. Nonetheless, in some embodiments, the design can be varied for more demanding applications. For example, the heights of ridges 101 in upper palm area may be between 2-8mm. Also, as shown in FIG. 2, knuckle area 120 and backhand area 118 may optionally comprise ridges 101. Figure 3 depicts a cross section taken along line 3-3 of the liner shown in FIG. 2, further displaying the width W, spacing S, and height H of ridges 101 disposed on top of main yarn 119. As discussed below, ridges 101 need not traverse a lateral circumference of liner 100 and instead include discontinuous ridges as is discussed below. Liner 100 may optionally comprise a cuff 116 having a size-adjustment, for example, by hook-and loop fasteners, such as a VELCRO® attachment. [0020] Ridges 101 comprise a yarn having a different size and/or stretchability than the main yarn. For example, and not limitation, for a light duty glove, ridges 101 comprise a textured nylon yarn. Embodiments of the invention also comprise where the main yarn and ridge yarn are different colors. For medium and heavy duty gloves, ridges 101 may comprise a SPANDEX@ or LYCRATM yarn core, which is wrapped with a nylon yarn, though design choices and selection are not limited thereto. [0021] Ridges 101 may be formed in several ways. One manner in which ridges may be formed is by the needle of the machine knitting over one part of the ridge 4 WO 2013/123038 PCT/US2013/025922 several times, building up a higher ridge with each pass. This can be accomplished by a model SWG machine. Another way in which ridges 101 can be formed is by changing the main yarn to the ridge yarn while varying stitch dimensions, for example, yarn tension. The tension of the yarn may be varied by adjusting the tension of the yarn between a pinch roller and a knitting head by computer control of a knitting machine, as is disclosed in commonly-assigned US Patent Application No. 11/444,806, which is herein incorporated by reference in its entirety. Stitch dimensions can also be controlled by varying the depth of penetration of the knitting needle into the knitted liner formed by the main yarn and by casting off or picking up additional stitches in a course. Ridges 101 may also be formed by variable plaiting the ridge yarn on top of the main yarn while varying tension of the ridge yarn. Ridges of this design may be formed with the SFG- and NSFG model machines. Substituting or plaiting one course at a certain tension forms a certain ridge height. Knitting two or more courses, such as three, four, five, etc., courses, provides a wider ridge as well as a greater height. Ridges formed in accordance with this embodiment of the invention allow both continuous ridges as well as discontinuous ridges, as is discussed below. Liners knitted in accordance with embodiments of the invention may optionally comprise polymeric material coatings as is discussed below. [0022] Figure 4 depicts the palm side of a liner according to embodiments of the invention. Liner 200 is shown in FIG. 4. Liner 200 may comprise ridges 101 on cuff 116, upper palm 112, back hand area 118, and on fingers 104, 106, 108, and 110. As shown, index finger 104 comprises seven sets of ridges 101, middle finger 106 comprises four sets of ridges 101, ring finger 108 comprises three sets of ridges 101, and pinky finger comprises one set of ridges 101. The crotches made between the palm 112 and index finger 104, middle finger 106, and ring finger 108 may optionally comprise a ridge 117. Ridge 117 may be only on palm side 112 and/or, alternately, on the back hand. Upper palm 112 includes four sets of ridges 101. In some embodiments, the height H of ridges 101 on the fingers may range from 0.5 to 1 mm. [0023] Figure 5 depicts the back side of the liner of FIG. 4, according to embodiments of the invention. Embodiments of the present invention may comprise 5 WO 2013/123038 PCT/US2013/025922 ridges 117 traversing the entire circumference of any region of liner 200. As is discussed below, ridges 117 need not traverse the entire circumference of any liner disclosed herein. Also, in some embodiments, spacing S may be approximately 2mm and Width W may be approximately 3mm. Upper palm 112 of liner 200 may comprise ridges 3mm in width W, 2mm in spacing S, and height H between 1-2mm. Cuff 116, which has twenty ridges 101, may have a height H of 1 mm, a spacing S of 2mm, and a width W of 3mm. The amount of ridges 101 may be varied to any practical number for a glove. Moreover, the size dimensions of ridges 101 may likewise be varied. Gloves of this design, which might be termed as having medium duty properties, have more ridges 101 having higher and wider dimensions, present a glove having superior gripability and impact resistance as compared with glove of FIGS. 1-3. Glove 200 may optionally comprise a cuff 116 having a size-adjustment, for example, by hook-and-loop fasteners or other fasteners. [0024] Figure 6 depicts the palm side of a liner according to embodiments of the invention. Liner 300 is shown in FIGS. 6-7. Liner 300 may comprise ridges 101 on cuff 116, and on fingers 104, 106, 108, and 110 and thumb 102. As shown, each of thumb 102, index finger 104, middle finger 106, ring finger 108, and pinky finger 110 comprises three sets of ridges 101. Thumb 102 further comprises a discontinuous ridge 105 on the palm side of liner 300 (as shown in FIG. 8 below), while having additional ridges 101 on fingers 104, 106, and 108. Cuff 116, which has ten sets of ridges 101, may have a height H of 1mm, a spacing S of 2mm, and a width W of 3mm. As discussed above, the amount of ridges 101 may be varied to any reasonable number on any finger, thumb, upper or lower palm, cuff, backhand area, or knuckle. As discussed above, the dimensions of ridges 101 may likewise be varied. Gloves of this design, which have more ridges 101 having higher and wider dimensions present a heavy-duty glove having superior gripability, cut-, and impact resistance as compared with either liner 100 of FIGS. 1-3 or glove 200 of FIGS. 4-5. [0025] Figure 8 depicts the left side view of FIG. 6, according to embodiments of the invention. Many of ridges 101 on lower palm 114 (as shown in FIGS. 6-7 as above), upper palm 112 and knuckle area 120 (as shown in FIG. 7) do not traverse the full circumference of liner 300, such as discontinuous ridges 105. Discontinuous 6 WO 2013/123038 PCT/US2013/025922 ridges according to embodiments of the invention of this design offer greater flexibility while nonetheless providing abrasion- and cut-resistance in specified areas of the gloves. In other words, ridges 101 may be present, optionally, only on the palm side or knuckle side of the glove, terminating without making a ring around the entire glove. Because of this feature, glove 300 has additional flexibility and comfort as well as cut resistance, abrasion resistance, and the like. Moreover, discontinuous ridges may also be on fingers 104, 106, 108, and 110 as well as thumb 102 in any embodiment of the present invention. Other ridge designs are possible within the scope of embodiments of the invention, such as those disclosed in commonly assigned US Patent Appl. No. 29/443,107, filed January 14, 2013, which is hereby incorporated by reference in its entirety. [0026] Figure 9 depicts a back hand view of dipped glove according to embodiments of the invention. Any knitted liner having ridges 101 may be coated with a polymeric material. For example, a latex coating may comprise a natural rubber latex, such as guayule or polyisoprene, synthetic latexes, such as synthetic polyisoprene, carboxylated acrylonitrile butadiene, non-carboxylated acrylonitrile butadiene, butyl latex, polychloroprene, nitriles, polyurethane, styrene-butadiene, acrylonitrile-butadiene, and the like, or blends thereof. The coating on liners 100, 200, 300 can comprise a palm dip, knuckle dip, finger dip, three-quarters dip, full dip, and the like as needed for specific applications using the dip processes as described in commonly assigned US Patent Appl. Publ. No. 2009/0211305, which is incorporated herein by reference in its entirety. Liners may be dipped or sprayed with a coagulant. The coagulant causes the polymeric coating to set on the fabric of the liner, preventing strikethrough of the coating. In FIG. 9, glove 400 comprises a polymeric coating dip 130. As shown, the back hand side of fingers and thumb, and back hand 118 are only partially covered with coating dip 130, and ridges 101 are similarly partially covered. [0027] Figure 10 depicts a palm side view of a dipped glove according to embodiments of the invention. In Fig. 10, glove 400 comprises a palm dip, in which the coating dip 130 completely covers the palm and the ridges 101 disposed thereon (not shown). Also, gloves in accordance with embodiments of the invention may 7 WO 2013/123038 PCT/US2013/025922 further comprise coatings that are foamed or unfoamed. Additionally, coatings may be built up in layers or in varying thickness. The layers may comprise the same or different polymeric materials. Additionally, the coatings may further comprise textured surfaces (not shown). [0028] All ranges recited herein include ranges therebetween, and can be inclusive or exclusive of the endpoints. Optional included ranges can be from integer values therebetween, at the order of magnitude recited or the next smaller order of magnitude. For example, if the lower range value is 0.1, optional included endpoints can be 0.2, 0.3, 0.4 . . . 1.1, 1.2, and the like, as well as 1, 2, 3 and the like; if the higher range is 8, optional included endpoints can be 7, 6, and the like, as well as 7.9, 7.8, and the like. [0029] While the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow. 8
