Description

Technical Field

[0001] Embodiments of the present disclosure relate generally to personal protective equipment, and more particularly, to thin coated support gloves with improved abrasion resistance, cut resistance, and methods of making the same. Background Art

[0002] Gloves are commonly used in many industries, such as construction, industrial and medical, as well as in the home, to protect the user's hands from abrasion, impact and physical injury. Support gloves are gloves with a fabric lining that is at least partially coated with a coating, such as a polymer coating. Support gloves combine durability with relative comfort.

[0003] Many such gloves include a polymer material as a coating, such as synthetic or natural latex or other elastomers, such as nitrile rubber and polychloroprene rubber. Some gloves have a foamed polymer coating to impart flexibility and other comfort-related properties. However, there continues to be a need for thin, flexible gloves that have increased cut resistance, either alone or in combination with abrasion resistance, particularly when a foamed coating is included, to minimize cracking during use and particularly during extended use, while maintaining flexibility and comfort.

[0004] Some manufactured gloves include a fabric lining that includes metal fibers or metal yarns. However, the inclusion of metal fibers or yarns in the fabric lining problematically reduces the flexibility of the glove and the adhesion resistance of the coating material applied to the fabric lining. Poor adhesion of the coating to the fabric lining reduces the overall durability of the glove, reducing cut resistance and abrasion resistance. In order to obtain strong adhesion, the properties of the polymer coating must be balanced with the properties of the knitted lining. Due to the smaller diameter of finer yarns and the smaller needles used therewith, the interstices of the knitted fabric may become too dense, thereby limiting the penetration of the polymer coating, resulting in poor adhesion. Conversely, if the interstices are too open, which is also possible when knitting small diameter yarns with larger needles, the polymer coating will completely penetrate the article, limiting flexibility and causing uncomfortable bleed-through for the user.

[0005] Therefore, there remains a need for a glove formed with a thin coated fabric liner that is abrasion and cut resistant, and a method of producing such a durable glove. Summary of the invention

[0006] Abrasion and cut resistant coatings and coated gloves and methods for making abrasion and cut resistant foamed or non-foamed coatings and coated gloves are more fully disclosed in the present invention, substantially as shown in and / or described in conjunction with at least one of the accompanying drawings herein. Various advantages and features of the present invention will be more fully understood through the following description and the accompanying drawings.

[0007] Provided herein are methods and apparatus for thin coated support gloves. In some embodiments, a thin coated support glove comprises: a thin knitted liner, the thin knitted liner comprising a plurality of finger components, a thumb component, a back of hand component, and a palm component, wherein the thin knitted liner comprises a covering yarn, the covering yarn comprising a tungsten core having a diameter of about 25-35 microns (e.g., about 28-about 32 microns), a polyamide wound yarn disposed on the tungsten core, and a high performance polyethylene wound yarn disposed on the polyamide wound yarn, wherein the covering yarn is 350 denier or less; a second yarn, wherein the second yarn is a blended yarn having a denier of 115 denier or less; and a thin polymer coating adhered to the thin knitted liner.

[0008] In an embodiment, the knit is a single knit. In an embodiment, the smooth side of the knit is toward the user's hand (inside). In an embodiment, the single knit is a plain knit, French terry, jersey fleece, mandarin duck, etc. In general, the various descriptions of the properties of the glove are independent of the cuff area. For example, the knitting style may be different. For example, where the body of the glove is a single knit, the cuff may, for example, be double knit, or knitted in a different style.

[0009] In some embodiments, a method for making a thin coated support glove is provided, the method comprising: trimming a 21 to 28 gauge knitted fabric liner (typically 21 to 23 gauge, such as 21 gauge (i.e., 21 needles per inch)) on a hand former; applying an aqueous coagulant solution to the 21 gauge knitted liner; dipping the 21 gauge knitted liner into a polymer emulsion, wherein the polymer emulsion is about 60 to about 100 parts per hundred (PHR) nitrile-butadiene (NBR) polymer formulation, forming a polymer coating on the knitted liner; and curing the polymer coating to form a thin coated support glove, wherein the 21 gauge knitted liner includes a plurality of finger components, a thumb component, a back of hand component, and a palm component, wherein the 21 gauge knitted liner comprises a covered yarn, wherein the covered yarn comprises a tungsten core having a diameter of about 25-35 microns, a polyamide wrapped yarn disposed on the tungsten core, and a high performance polyethylene wrapped yarn disposed on the polyamide wrapped yarn, wherein the covered yarn is 350 denier or less. In an embodiment, the aqueous coagulant solution comprises less than 40 wt % of a weak acid.

[0010] In an embodiment, the polymer emulsion is about 70 to about 100 parts, or about 80 to about 100 parts, or about 90 to about 100 parts, or about 100 parts NBR. The second polymer can be, for example, natural rubber, synthetic polyisoprene, styrene-butadiene, carboxylated or non-carboxylated 10 acrylonitrile-butadiene, polychloroprene, polyacrylic acid, butyl rubber or water-based polyurethane (polyester-based or polyether-based) or a combination thereof.

[0011] In some embodiments, a thin coated support glove comprises: a 21-gauge knit liner comprising a plurality of finger components, a thumb component, a back of hand component, and a palm component, wherein the 21-gauge knit liner comprises a cover yarn comprising a tungsten core having a diameter of about 25-35 microns, a polyamide wrapped yarn disposed on the tungsten core, and a high performance polyethylene wrapped yarn disposed on the polyamide wrapped yarn, wherein the cover yarn is 350 denier or less; a second yarn of 115 denier or less, the second yarn comprising nylon and spandex; and a thin polymer coating adhered to the 21-gauge knit liner.

[0029] Figure 2 A diagram of a second covered yarn 200 according to an embodiment of the present disclosure is shown. In an embodiment, the second covered yarn 200 includes a core yarn 202 and a blended yarn 204 covering the core yarn 202. In at least one embodiment according to the present disclosure, the core yarn 202 is an elastic yarn, such as an elastic yarn and / or a polyester yarn, such as Or spandex. The core yarn 202 may be, for example, 20-80, 40-70, such as a yarn of 70 denier. In addition, in at least one embodiment according to the present disclosure, the blended yarn 204 is a nylon or polyamide yarn, such as nylon 6 or nylon 6,6 yarn (also expressed as nylon 66). In at least one embodiment according to the present disclosure, the blended yarn 204 is a yarn of about 30 to about 50 deniers, such as a yarn of 40 deniers. In some embodiments, the total denier of the second covered yarn 200 in some embodiments may be about 115 deniers. In an embodiment, the second covered yarn 200 includes a blended yarn 204 and a core yarn 202, wherein the blended yarn 204 includes or is composed of a polyamide yarn of about 40 deniers or less (e.g., about 30 to about 45 deniers or 50 deniers), and the core yarn 202 includes or is composed of a polyether-polyurea copolymer yarn of about 70 deniers or less (e.g., about 60 to about 70 deniers). In some embodiments, the second yarn is about 115 denier or less, or between about 105 denier and about 115 denier. In an embodiment, the second yarn has a total denier suitable for use in a 21 gauge needle.

[0030] Embodiments according to the present disclosure also include yarns, wherein the second coated yarn may further include polyester yarns, filaments, staple fibers, etc. Embodiments according to the present disclosure also include yarns, such as high performance polyethylene (HPPE) or ultra-high molecular weight polyethylene (UHMWPE) yarns, filaments, staple fibers, etc. Embodiments according to the present disclosure also include para-aramid and / or meta-aramid yarns, fibers and / or filaments. Any yarn considered herein may include glass fibers, steel yarns, ceramic fibers, and other fibers and filaments known to those skilled in the art.

[0031] In some embodiments, the first covered yarn 100 and / or the second covered yarn 200 has a thickness suitable for knitting using a 21 gauge needle. In an embodiment, the first covered yarn and the second covered yarn individually or in combination have a thickness suitable for insertion into and use in a knitting machine.

[0032] Figure 3A diagram of a thin knitted liner 300 according to an embodiment of the present disclosure is shown. In an embodiment, the thin knitted liner 300 includes a thumb 302, an index finger 304, a middle finger 306, a ring finger 308, a little finger 310, a knuckle area 312, and optionally, a cuff area 314 and / or a hem 316. The thin knitted liner 300 also includes an opening 318 for a wearer to put on the thin knitted liner 300 or for placing the thin knitted liner on a former for subsequent coating, as described herein. It should be understood that the thin knitted liner 300 may also include a palm area not shown in this view. In an embodiment, the thin knitted liner 300 is knitted using a knitting machine. The thin knitted liner 300 is knitted using, for example, the first covered yarn 100 or the second covered yarn 200 as described above in an amount sufficient to form the thin knitted liner 300. In some embodiments, the first covered yarn 100 and the second covered yarn 200 can be combined in a plating technique to form a fabric, such as a knitted liner 300 according to the present disclosure. For example, the first covered yarn 100 and the second covered yarn 200 can be fed to the knitting machine simultaneously, so that the first covered yarn 100 is placed below the second covered yarn 200, and / or so that each yarn can be wound to a specific side of the fabric. In an embodiment, the first covered yarn 100 forms a layer of material adjacent to or below a layer of the second covered yarn 200. In an embodiment, a coating can be applied to a layer of the second covered yarn 200 in a fabric (e.g., a knitted liner 300), or to a layer of the first covered yarn 100. As further described below, embodiments according to the present disclosure also include a coating for forming a support glove.

[0033] Figure 4 A diagram of a thin knitted liner 300 having a thin coating 450 disposed on the thin knitted liner 300 is shown, forming a thin support glove 400, according to an embodiment of the present disclosure. In an embodiment, the thin support glove 400 includes a coated thumb 402, a coated index finger 404, a coated middle finger 406, a coated ring finger 408, a coated pinky 410, a coated knuckle area, an uncoated cuff area 314, and / or optionally a rolled edge 316. Alternatively or additionally, the thin coating 450 is indicated by a darker shaded area, noting that the texture of the thin knitted liner 300 can still be seen below the thin coating 450. The cross-sectional thickness of the coated area of ​​the thin lightweight support glove 400 is typically in the range of 0.80 mm to 1.20 mm, or approximately within the range of 0.9 mm. Table 2 below shows additional cross-sectional thicknesses of gloves of the present disclosure. The thin support glove 400 also includes an opening 318 for the wearer to wear the thin support glove 400.

[0034] It should be understood that the thin knitted liner 300 also includes a coated palm area, which is not shown in this view. Embodiments according to the present disclosure also include a coating for forming a support glove, wherein a three-quarter immersed support glove covers the upper back of the hand area 420 with a thin coating 450. It should also be understood that other types of immersion known to those skilled in the art are also within the scope of the presently disclosed embodiments of the thin coated support glove. For example, embodiments optionally include a knuckle-immersed support glove (where the upper back of the hand area 420 will not be coated), a full-immersion support glove, a palm-immersed support glove, etc.

[0035] The inventors unexpectedly overcame the problems associated with previous methods of coating thin linings containing metallic materials with thin coatings. Thus, optionally, a 21-gauge knitted lining comprising one or more thin coated yarns as described herein, including coated yarns having a tungsten core, can be coated with an aqueous polymer emulsion (e.g., aqueous polyurethane) and / or a blend of aqueous polyurethane with other aqueous emulsions. For example, a blend of a nitrile-butadiene (NBR) emulsion with an aqueous polyurethane emulsion. In addition, a 21-gauge knitted lining can be coated with aqueous NBR or NBR blends. The inventors unexpectedly produced a thin knitted lining 300 in which a thin coating 450, even more particularly with respect to disposing a thin aqueous polymer coating, is disposed on the thin knitted lining 300, thereby producing a thinly coated support glove that is thin, flexible, durable, and optionally breathable.

[0036] According to an embodiment of the present disclosure, the thin support glove 400 includes a thin coating 450, wherein EN388 (2016) level 4 wear (>8000 cycles) is achieved despite being thin. Alternatively, in some embodiments, the thin coating 450 is unfoamed but maintains breathability and wear resistance. Without being bound by theory, it is believed that the thin knitted liner 300 and the thin coating 450 are each integrally formed inside each other when forming the thin coated support glove 400, and because the yarn is penetrated by the thin coating 450 without an uncomfortable amount of strikethrough. This integration allows, for example, the formation of a "channel", thereby providing breathability. In addition, the excellent adhesion of the yarn and the thin coating provides high wear, despite the thin coated support glove being thin and containing metal. In this article, integrally formed means that the yarn of the thin knitted liner 300 is penetrated by the thin coating 450 to the extent that disassembly is impossible without destroying one or more of the thin knitted liner 300 or the thin coating 450.

[0037] According to an embodiment of the present disclosure, at least one thin coating 450 is prepared using a chemical formula that does not contain dimethylformamide (DMF) as described in Table 1. The polymer emulsion can have a low viscosity, and as an example and not limitation, the viscosity range is 300-2000 centipoise. In some embodiments, the polymer emulsion uses a very low viscosity polymer formulation, but still has a high total solid content, such as 35-45%. In some embodiments, the polymer emulsion may include a commonly used stabilizer, including but not limited to potassium hydroxide, ammonia, aluminum sulfate, sulfonates, and other stabilizers known to those skilled in the art. The polymer emulsion may include other commonly used components, such as surfactants, antimicrobial agents, fillers / additives, etc. The amounts of the components in Table 1 are expressed as parts by weight of dry rubber (PHR) known to those skilled in the art. (All amounts and ranges may be approximately this amount, from about to about.) It is not necessary to include all the ingredients shown in Table 1, for example, waxes, pigments, and thickeners may not be present in some embodiments.

[0038]

[0039] The polymer emulsions shown in Table 1 above include unexpectedly low viscosities while having very high total solids contents (TSC), allowing the thin coating to penetrate the fibers that make up the yarn while still inhibiting print-through, i.e., where the polymer emulsion penetrates far enough into the thickness of the liner to contact the skin when the glove is worn. At least one exemplary embodiment according to the present disclosure includes a formulation that unexpectedly has a TSC of 35 to 45% and a viscosity of 300-2000 centipoise. In addition, at least one embodiment according to the present disclosure includes a thin coating 450 that is treated with a weak acid coagulant such as acetic acid, formic acid, tricarboxylic acid and other weak acids or any mixture of these weak acids so that the interior molecules of the coating form additional crosslinks. The thin coating 450 can then be treated with a strong coagulant to more completely gel and crosslink the outer molecules, producing a fully hardened thin coating 450 that is the opposite of surface hardening (a coating in which only the outer surface of the coating is completely crosslinked), i.e., gelled or crosslinked throughout the thickness of the polymer layer. Techniques for producing a through-hardened thin coating 450 are disclosed in commonly assigned U.S. Publication No. 2014-0000006, entitled “Abrasion and Cut Resistant Coating and Coated Glove,” the entire contents of which are incorporated herein by reference.

[0040] Referring to Table 1, in some embodiments, ammonia may be present in an amount of about 0.1 to about 0.3 PHR or about 0.2 PHR. In some embodiments, a curing agent such as zinc oxide may be present in an amount of about 2.5 PHR to about 4.5 PHR, such as about 3.00 PHR. In some embodiments, waxes and / or lubricants may be present in an amount of about 0.2 PHR to about 2.5 PHR or about 0.8 PHR. In some embodiments, a pigment may be present in an amount of about 1.0 PHR to about 3.0 PHR, such as 1.2 PHR. In some embodiments, a thickener may be present in an amount of about 0.01 PHR to about 0.2 PHR or about 0.1. In an embodiment, the polymer emulsion may include a total solids content of 35-45% by weight of the total composition.

[0041] In addition, at least one embodiment according to the present disclosure includes a thin coating 450 treated with a salt treatment. Optionally, the thin coating 450 may be treated with a salt bath before or after the curing step, the salt bath containing salt particles, such as sodium chloride salt particles. In addition to being embedded in the thin coating 450 (wherein a multi-faceted texture is imparted, providing enhanced gripping properties), the salt particles also provide additional strength, i.e., wear resistance, to the thin coating 450. The technology of treating the thin coating 450 with a salt bath treatment is disclosed in commonly assigned U.S. Patents No. 7,378,043, No. 7,771,644, No. 7,814,570, and No. 8,522,363, and the above-mentioned disclosed technology is incorporated herein by reference in its entirety.

[0042] Figure 5A method 500 for making a thin coated support glove according to an embodiment of the present disclosure is shown. The method 500 starts at step 502 and proceeds to step 504, in which a liner such as a No. 21 knit liner as described herein is trimmed onto a former such as a hand-formed former. In step 506, the former such as a hand-formed former with a No. 21 knit liner disposed thereon is immersed in a coagulant such as a coagulant solution and removed. In some embodiments, the coagulant solution comprises a weak acid such as acetic acid at a water concentration of less than 40%. In an embodiment, the weak acid at the water concentration may further comprise a surfactant. In some embodiments, the thin knitted liner with the coagulant solution contacts a polymer emulsion, wherein it destabilizes the polymer emulsion and gels the emulsion. Without being bound by theory, it is believed that the weak acid coagulant allows the thin coating to penetrate, fully harden, and adhere to the thin knitted liner of the present disclosure. In addition, optionally, the coagulant solution disposed on the thin knitted liner can be heated to dry the coagulant solution. In addition, optionally, the 21-gauge knitted liner of the present disclosure is first provided with a wetting agent before being immersed in the coagulant solution. In some embodiments, the liner of the present disclosure can be covered using the method described in International Patent Publication No. WO 2018 / 145145 entitled "Thin Coated Supported Glove" by Fernando et al. (incorporated herein by reference in its entirety).

[0043] In step 508, the former (e.g., a hand-formed former) having a No. 21 knit liner trimmed thereon is then dipped into a polymer emulsion (e.g., a polymer emulsion produced by the formulation described in Table 1). The polymer emulsions in Table 1 typically have very low viscosities, e.g., 300-2000 centipoise. The polymer emulsion and the yarn that penetrates the knit liner also unexpectedly do not penetrate the entire thickness of the knit liner through the interstices, thereby producing a thin coating that adheres well to the knit liner without causing print-through, which may be uncomfortable for the wearer of the support glove. The hand-formed former may be dipped and removed as described above in a palm dip, three-quarter dip, full dip, etc., to form a polymer coating on the No. 21 thin knit liner. In step 510, the former (e.g., a hand-formed former) with the thin knit liner and the polymer coating is then transported to a curing oven and cured at a temperature of 90-130 degrees Celsius for 30 to 70 minutes.

[0044] At step 512, the thin support glove is peeled off the hand former and the method 500 ends. Other steps may be included in the method 500. For example, a washing step in hot water may be performed before the curing step or after the curing step. In addition, a salt treatment and / or a weak acid treatment as described above may be used. Typically, the salt treatment is performed before the curing step. In addition, typically, a weak acid treatment may be performed before and / or after the curing step.

[0045] In an embodiment, at the yarn intersection, when a yarn of a preselected denier is used, the knitted lining may have a thickness of about 0.5 mm to 0.8 mm. Table 2 below shows additional knitted lining thicknesses suitable for use according to the present disclosure. In addition, at the yarn intersection, when a 350 denier yarn is used, the knitted lining may have a thickness of about 0.6 mm. Wherein a 21-gauge knitted lining is coated with a polymer emulsion to form a coating, the coating thickness may be close to the thickness of the thin knitted lining, and the lightweight thin support glove may have a final thickness in the range of, for example, 0.80 mm to 1.2 mm. Table 2 below shows the additional thickness of a glove according to the present disclosure. Similarly, the total weight of a lightweight thin support glove including a 21-gauge knitted lining and a thin polymer coating may be lighter than a similar glove having EN388 (2016) level 4 wear. Alternatively or additionally, embodiments of the present disclosure include support gloves in which a coating (e.g., a full coating, a 3 / 4 coating, a palm coating, or a knuckle coating), such as thin coating 450, is a continuous coating. For example, thin coating 450 covers a thin knitted liner, such as thin knitted liner 300, without gaps.

[0046] In embodiments, the thickness of the glove can be varied to obtain a predetermined level of cut resistance. For example, a thin coated support glove of the present disclosure can be formed, wherein the glove has a thickness of about 0.7 to about 0.9 mm (e.g., about 0.75 to about 0.85 mm, or about 0.8 mm) and a cut resistance of A5 (according to ANSI / ISEA 105 (2016 Edition)), a thickness of about 0.8 to about 1.0 mm (e.g., about 0.85 mm to about 0.95 mm, or about 0.9 mm) and a cut resistance of A5, or a thickness of about 1.0 to about 1.2 mm (e.g., about 1.05 mm to about 1.15 mm, or about 1.1 mm) and a cut resistance of A7. In embodiments, the thickness of the yarn and / or the thickness of the coating can be varied to provide a glove of a predetermined thickness. Table 2 below shows the additional cut resistance of the glove / liner thickness according to the present disclosure. The gloves of the present invention can generally have a cut resistance of A5, A6 or A7.

[0047] As mentioned above, the size of the knitting needles used is generally selected based on the denier of the yarn used. Although a larger size needle can be used to knit a yarn of smaller denier (i.e., a yarn of smaller diameter), this combination results in excessive gaps (i.e., spaces) between the rows of yarns in a thin knitted liner that are larger than the desired gaps. When the appropriate needle size is selected, the gap spacing is generally in the range of one to three times the yarn diameter used to knit the liner. In addition, when the liner is placed on the former, the difference between the yarn diameter and the space changes, so that due to the stretching of the thin knitted liner, the gap diameter can be three times larger than the yarn diameter.

[0048] As described above, coating a knitted liner can be challenging. A 21 gauge knitted liner made from a coated double-ply yarn (e.g., the first coated yarn and the second coated yarn described herein) can be about 0.5 to 0.6 mm thick. Coating a 21 gauge knitted liner with a polymer emulsion to form a coating can result in a glove thickness of about 0.80 mm to 0.90 mm. A glove having a 21 gauge knitted liner coated with, for example, a nitrile-butadiene (NBR) emulsion or an NBR blend of the emulsion has integrally formed permeability and can have a thickness that is almost equal to the thickness of the knitted cloth liner, which is approximately 0.50 to 0.6 mm. In at least one embodiment according to the present disclosure, the emulsion penetrates between about 40-75% of the thickness of the knitted liner. In at least one embodiment according to the present disclosure, the emulsion penetrates less than about 60% of the thickness of the knitted liner, in some embodiments, less than about 50% of the thickness of the thin knitted liner, and in some embodiments, less than about 40% of the thickness of the thin knitted liner.

[0049] In one or more embodiments according to the present disclosure, the polymer emulsion is coated on selected portions of the glove, which generally include the palm and finger (particularly palm side) areas of the glove, while the liner is not coated with the polymer emulsion on the back of the hand, where the breathability is further improved. However, due to the breathability of some thin knitted liner and thin coating embodiments, the full-immersion style remains an unexpected advancement in the art. In addition, in embodiments according to the present disclosure, the polymer emulsion includes natural rubber, synthetic polyisoprene, styrene-butadiene, carboxylated or non-carboxylated acrylonitrile-butadiene, highly carboxylated acrylonitrile-butadiene (e.g., greater than 35% carboxylation), chloroprene, polyacrylic acid, butyl rubber or water-based polyurethane (polyester-based or polyether-based) or a combination thereof.

[0050] In at least one embodiment according to the present disclosure, a dispersed bubble foamed polymer coating, such as a thin coating, in the range of 5-60% by volume is used to form closed cells or open cells with interconnected pores in the polymer layer. The closed cells provide a highly flexible, soft and spongy liquid-proof polymer coating and provide good dry and wet grip. Closed cells are generally associated with air content in the range of 5 to 15% by volume. Interconnected open cells are generally present in the range of 15-50% air volume and provide breathability of the glove through the foamed polymer layer.

[0051] Due to the smaller diameter of the yarn that can form the thin knitted liner, the distance between the fibers decreases rapidly, thereby forming a pinch area in the knitted liner, and when the polymer emulsion enters this area, the gelling action of the coagulant applied to the liner substantially blocks the entry of the polymer emulsion, wherein the polymer emulsion is substantially prevented from penetrating through the gaps into the thickness of the thin knitted liner. This penetration and gelling action are a function of the viscosity of the polymer emulsion and the depth to which the former with the coagulant coated liner is pressed into the polymer emulsion. The higher the hydrostatic pressure, i.e., the deeper the penetration, the deeper the polymer emulsion penetrates into the thin knitted liner. Therefore, among the controllable process variables for controlling the penetration of the polymer emulsion into the thin knitted liner are 1) control of the viscosity of the polymer emulsion and 2) the immersion depth of the former for knitted liner finishing. Compared to a size 18 glove, the thin, lightweight support glove described herein is approximately 30% less in weight and thickness and has more than 3 times better flexibility.

[0052] Flexibility can be measured on a cut-away coated portion of the glove by the Gurley Stiffness Test using a Gurley Model 4171S. The test specimen is taken from the palm area and the dimensions of the specimen are 50.8 mm (2 inches) x 25.4 mm (1 inch) to give a deflection between 1 and 7 on the scale of the Gurley flexure / stiffness tester. The rectangular specimen is clamped in the center with 6.4 mm (0.25 inches) held in the jaws without being stretched in the specimen grip.
