Description

Technical Field

[0001] This invention relates to a clothing material and garments comprising said clothing material, such as gloves. This invention also relates to a method of manufacturing said clothing material. Background Technology

[0002] Single-use clothing materials, such as gloves, are very common in a variety of medical and non-medical applications, such as scientific laboratories, food preparation, or cleaning work.

[0003] These gloves are typically made of a single-layer polymer material, such as latex, nitrile butadiene rubber (NBR), polyvinyl chloride (PVC), or neoprene, which provides a degree of protection for the user's hands against certain chemical and biological agents. Single-use disposable gloves offer the user excellent dexterity, enabling them to perform tasks accurately while being protected by the gloves.

[0004] However, the protection provided by single-use disposable gloves is far from optimal in many situations. In particular, single-use disposable gloves have poor mechanical strength. Specifically, they exhibit poor tear resistance, cut resistance, and abrasion resistance. Once torn, cut, or abraded, any chemical or biological protection provided by single-use disposable gloves will be lost.

[0005] Furthermore, the low mechanical strength of single-use disposable gloves means they can only be used reliably once. Their durability is insufficient for multiple uses and / or washing. The polymer materials used in single-use disposable gloves are non-biodegradable. Therefore, single-use disposable gloves typically require landfill disposal.

[0006] Single-use gloves are manufactured on ambidextrous hand molds and are not specifically designed for use on either the left or right hand. This can result in poor glove fit and noticeable wrinkles, reducing the user's dexterity and potentially causing the gloves to get caught on machinery, posing a risk to the user.

[0007] While gloves in the past could combine high mechanical strength and washability, these properties traditionally required thicker glove materials, which significantly compromised the user's dexterity and comfort.

[0008] This invention is designed based on the above considerations. Summary of the Invention

[0009] According to a first aspect, the present invention provides a garment material comprising: a first layer, wherein the first layer is a molded polymer; a second layer, wherein the second layer is a molded polymer disposed at one or more locations on the first layer, the second layer having the shape of the first layer at the one or more locations; and a textile layer; wherein the second layer is located between the first layer and the textile layer; wherein the second layer includes a lining embedded in the molded polymer of the second layer. The lining is made of yarn and has gaps passing through it. The yarn of the lining has a unit length weight of 10 to 60 denier; and the lining has a weight of 5 to 35 g / m² in the garment material or in areas of the garment material. 2 Weight per unit area.

[0010] The clothing material of this invention can be recycled through multiple washes, which significantly reduces the amount of clothing (e.g., gloves) that needs to be disposed of, thus reducing the environmental impact of traditional clothing.

[0011] While gloves typically reduce a wearer's dexterity to some extent, it is preferable to minimize the impact of gloves on the wearer's dexterity and comfort. The garment material exhibits excellent dexterity properties.

[0012] Gloves made from the aforementioned garment material can be molded to precisely fit each of the wearer's hands, resulting in a more snug fit compared to ambidextrous gloves that fit either hand. This reduces wrinkles during use, increasing user comfort and dexterity compared to similar but ambidextrous gloves. Furthermore, using anatomically designed gloves reduces the risk of the glove getting stuck in machinery, thereby lowering the risk of hand injury during use.

[0013] Preferably, the thickness of the clothing material is 0.1 mm to 1.0 mm, for example 0.3 mm to 0.7 mm, which helps to improve the user's dexterity.

[0014] The garment material also exhibits significantly better physical properties than disposable gloves in at least three different aspects. For example, gloves made from the garment material of the present invention have been found to have: - 6% more cut-resistant than traditional single-use disposable gloves. -63% to 2800% greater abrasion resistance than traditional single-use disposable gloves, and -600% to 1700% more tear-resistant than traditional single-use disposable gloves.

[0015] The clothing materials for which protection is sought also exhibit beneficial chemical resistance to sodium hydroxide, hydrogen fluoride, and isooctane. The clothing materials provide the highest level of protection against sodium hydroxide and isooctane.

[0016] Of particular surprise, in some cases, gloves made from the clothing material claimed in this invention have shown to offer better dexterity than bare hands.

[0017] In all tests conducted, these gloves significantly improved finger and hand dexterity compared to conventional chemical-resistant gloves disclosed in WO 2019 / 229427 A1.

[0018] It is known that clothing materials and gloves possess some of the aforementioned desired properties, but known clothing materials do not exhibit all of these properties, or their performance does not reach the desired level, particularly in terms of the dexterity and comfort expected by the user.

[0019] Garments that include linings embedded in polymer materials are called supportive garments. It was previously thought that using supportive gloves always significantly affected dexterity compared to unlined, unsupportive gloves.

[0020] However, the inventors of this case were surprised to find that in clothing materials (such as gloves) that can be recycled multiple times through washing, they can improve cut resistance, abrasion resistance and tear resistance while maintaining excellent dexterity.

[0021] According to a second aspect, the present invention provides a garment comprising the clothing material of the first aspect. The garment may be an overcoat (e.g., a raincoat), apron, hood, boots, shoes, socks, work clothes, waders, trousers, or gloves.

[0022] Preferably, the garment is a glove. Preferably, the garment is a glove, wherein the lining has a density of 5 to 35 g / m² in the palm and / or finger area of ​​the glove. 2 Weight per unit area.

[0023] When the garment is a glove, preferably, the thickness of the garment material in the palm and / or finger area of ​​the glove is 0.1 mm to 1.0 mm, for example 0.3 mm to 0.7 mm, which is beneficial to improving the user's dexterity.

[0024] WO 2019 / 229427 A1 discloses gloves made of natural rubber (NR) or nitrile rubber (NBR) having a lining comprising “41% 100D Dyneema® (UHMWPE), 22% 50D glass fiber yarn and 37% nylon 6 yarn”, wherein the lining has a density of 117 g / m² in the palm area. 2(11.7 mg / cm) 2 The unit area weight of the gloves, and the gloves described herein have three coatings comprising natural rubber in the first layer. WO 2019 / 229427 A1 does not disclose a lining of yarn having a unit length weight of 10 to 60 denier, and having a weight of 5 to 35 g / m² in the garment material or in areas of the garment material. 2 Weight per unit area.

[0025] Compared to conventional gloves (such as those disclosed in WO 2019 / 229427 A1), the gloves of the present invention offer significant and surprising benefits in reducing the glove’s impact on the user’s dexterity and comfort, while maintaining key properties such as chemical resistance and mechanical resistance.

[0026] Without hindsight, WO 2019 / 229427 A1 did not provide the necessary hints to the technicians that they could achieve this optimal combination of dexterity, chemical resistance, and mechanical resistance by using lighter materials for the lining, especially when the lining has a lower yarn weight and a lower knit density.

[0027] According to a third aspect, the present invention provides a method for manufacturing a garment material, the method comprising: providing a first layer, the first layer being a molding polymer; applying a lining to the first layer, wherein the lining is formed of yarn and has gaps passing through the lining; applying a fluid polymer material to the lining such that the fluid polymer material permeates through the gaps in the lining; curing the fluid polymer material to form a second layer comprising the lining embedded in a solid polymer material; and applying fibers to form a textile layer. The yarns of the lining have a length-to-weight ratio of 10 to 60 denier, and the lining has a density of 5 to 35 g / m² in or in areas of the garment material. 2 The weight per unit area. The clothing materials of the first aspect and / or the clothing of the second aspect can be obtained by the methods of the third aspect (e.g., already obtained).

[0028] It should be understood that embodiments disclosed with respect to one aspect of the invention are equally applicable to other aspects of the invention, unless they are incompatible. Detailed Implementation

[0029] The garment material can be formed into a liquid-impermeable and chemically resistant glove to protect the wearer's hands. Preferably, the garment material forms at least a portion (e.g., 50% or more, or all, of the glove's finger and / or palm areas) of the glove.

[0030] It should be understood that the clothing material, garment, or part of the garment is flexible. The clothing material of the present invention is suitable for producing a range of garments. Garments including the clothing material can be outerwear (e.g., raincoats), aprons, boots, shoes, socks, work clothes, waders, trousers, and / or gloves.

[0031] The thickness of the clothing material is preferably 1.0 mm or less, for example 0.8 mm or less, or 0.7 mm or less, particularly 0.6 mm or less, for example 0.5 mm. The thickness of the clothing material can be 0.1 mm or greater, for example 0.3 mm or greater, or 0.4 mm or greater, for example 0.5 mm. The thickness of the clothing material can be from 0.1 mm to 1.0 mm, preferably from 0.3 mm to 0.7 mm, or from 0.4 mm to 0.6 mm.

[0032] The total thickness of the first layer can be 0.6 mm or less, for example, 0.4 mm or less, and the thickness of the second layer can be 0.6 mm or less, for example, 0.4 mm or less. The total thickness of the first layer can be from 0.001 mm to 0.6 mm, for example, 0.01 mm to 0.3 mm, and the thickness of the second layer can be from 0.001 mm to 0.6 mm, for example, 0.01 mm to 0.3 mm.

[0033] In this embodiment, the garment is seamless, meaning it is made from a single piece of garment material, rather than from two or more pieces of garment material joined together (e.g., by stitching). Seamless garments can be achieved by manufacturing the garment on a mold that has a shape corresponding to the garment.

[0034] First layer The first layer corresponds to the outermost layer of the garment when in use. The first layer of the garment material and / or garment may have an outer surface (i.e., a surface that does not contact the second layer), wherein part or all of the outer surface has a texture (e.g., uneven or rough, rather than smooth).

[0035] The first layer may comprise a single layer of polymer material. The first layer may comprise two or more polymer material sublayers (or coatings). Preferably, the first layer comprises one to three polymer material sublayers. Most preferably, the first layer comprises two polymer material sublayers.

[0036] The ability to vary the number of sublayers in a first layer with multiple sublayers can offer benefits in terms of altering the thickness of the resulting garment material and, consequently, its resistance to chemical agents and / or physical effects. For gloves, it may be useful to use a thicker material (more sublayers) from the fingers to the wrist and a thinner material (fewer sublayers) at the cuffs to provide greater mechanical strength in these areas that typically experience more physical action. Multiple sublayers are useful because they allow for the use of a variety of different polymer materials in the first layer. For example, it may be necessary for the outermost coating to have different properties (chemical resistance, color, etc.) than the inner coatings.

[0037] It should be understood that both the first layer and the resulting garment material are typically flexible. The flexibility of the garment material is desirable to ensure comfort and allow the wearer freedom of movement. Using fewer polymer sublayers can reduce the thickness of the first layer, thereby minimizing the adverse effects on the wearer's dexterity caused by the garment (e.g., gloves).

[0038] The first layer of molding polymer can have the shape of a complete garment, such as gloves, socks, shoes, or boots, or the molding polymer can have the shape of a portion of such garment. If a sheet of garment material is required, the first layer of molding polymer can be a polymer sheet. Preferably, the first layer is molded into a glove (i.e., a hand shape).

[0039] A variety of polymer materials are suitable for the first layer. The polymer for the first layer can be a polymer or mixture of polymers selected from the following list: acrylic latex, NBR, nitrile latex, natural latex, polyvinyl chloride (PVC), polyvinyl acetate (PVA), chloroprene rubber (polychloroprene), PU latex, butyl rubber (a copolymer of isobutylene and isoprene, also known as IIR), polyisobutylene (also known as “PIB” or polyisobutylene rubber), polyvinyl alcohol, and fluoropolymer elastomers (including elastomers sold under the VITON® brand).

[0040] The first layer may contain polymers or mixtures of polymers selected from the list of acrylic latex, nitrile latex, natural latex, chloroprene rubber, and butyl rubber.

[0041] The first layer preferably comprises two sublayers (e.g., consisting of two sublayers or substantially consisting of two sublayers), wherein each sublayer comprises a mixture of latex selected from acrylic latex, nitrile latex and natural latex (e.g., consisting of or substantially consisting of said mixture).

[0042] The total thickness of the first layer (i.e., including any sublayers) can be 0.6 mm or less, or 0.4 mm or less, preferably 0.3 mm or less, such as 0.2 mm or less, or 0.19 mm or less. The total thickness of the first layer can be 0.001 mm or more, or 0.01 mm or more, such as 0.05 mm or more, such as 0.07 mm or more, or 0.08 mm or more. The total thickness of the first layer can be from 0.001 mm to 0.6 mm, such as 0.01 mm to 0.3 mm, such as 0.07 mm to 0.2 mm. The first layer is flexible.

[0043] Second floor The second layer is supported on the first layer. The second layer covers part or all of the first layer, and when the second layer covers the first layer, the second layer has a shape corresponding to the first layer.

[0044] The second layer can be formed by applying a fluid polymer material to the liner to penetrate the gaps in the liner. The fluid polymer material can then be cured to form the second layer, in which the liner is embedded in the solid polymer material. It should be understood that the resulting solid polymer material (and the second layer) is flexible, not rigid.

[0045] The fluid polymer material covers part or all of the first layer and necessarily conforms to the shape of part or all of the first layer. Therefore, the first and second layers are aligned. In one embodiment, the fluid polymer material of the second layer covers the entire first layer.

[0046] It should be understood that sufficient fluid polymer material must be applied to completely cover and coat the lining. If the lining is absorbent, it can be "soaked" in the fluid polymer material. Therefore, the minimum thickness of the second layer should be comparable to the thickness of the lining. Alternatively, an excess of fluid polymer material may be applied, making the second layer thicker than the lining.

[0047] The thickness of the second layer can be 100% or greater, or 120% or greater, such as 150% or greater, or 180% or greater, such as 200% or greater. The thickness of the second layer can also be 400% or less, such as 300% or less, or 200% or less, such as 150% or less, or 130% or less. The thickness of the second layer can also be between 100% and 400% of the lining thickness, such as 100% to 200%, or 100% to 150%. While a thick coating can be applied to the lining, this increases the overall thickness of the garment material and thus reduces the flexibility of the garment material and the dexterity of the gloves made from said material.

[0048] The thickness of the second layer (which includes the lining) can be 0.6 mm or less, 0.6 mm or less, or 0.4 mm or less, preferably 0.3 mm or less, for example 0.27 mm or less, or 0.25 mm or less. The thickness of the second layer can be 0.001 mm or more, or 0.01 mm or more, for example 0.05 mm or more, for example 0.10 mm or more, or 0.15 mm or more, for example 0.18 mm or more, or 0.20 mm or more. The thickness of the second layer can be from 0.001 mm to 0.6 mm, for example 0.01 mm to 0.3 mm, for example 0.15 mm to 0.27 mm.

[0049] The polymer in the second layer can be a polymer or mixture of polymers selected from the list of the following: acrylic latex, nitrile rubber (NBR), nitrile latex, natural latex, polyvinyl chloride (PVC), polyvinyl acetate (PVA), chloroprene rubber (polychloroprene), PU latex, butyl rubber (a copolymer of isobutylene and isoprene, also known as IIR), polyisobutylene (also known as “PIB” or polyisobutylene rubber), polyvinyl alcohol, and fluoropolymer elastomers (including elastomers sold under the VITON® brand).

[0050] The polymer in the second layer can be a polymer or a mixture of polymers selected from the list of acrylic latex, NBR, nitrile latex, natural latex, chloroprene rubber and / or butyl rubber.

[0051] The polymer in the second layer can be a polymer or a mixture of polymers selected from the list of acrylic latex, NBR and acrylic latex.

[0052] Fluid polymer materials can be applied by impregnation, i.e., immersing (or submerging) a first layer with a lining into a container (e.g., a bathtub or tank) containing the fluid polymer material, such as a solution or suspension of the polymer material, optionally with other components.

[0053] Fluid polymer materials can be applied directly to the liner (i.e., without first applying a coagulant to the liner). In conventional methods, coagulants are often used to help the fluid polymer material solidify on the substrate. However, using a coagulant on the liner can hinder the penetration of the fluid polymer material (which is essentially an adhesive coating) into the liner.

[0054] Preferably, excess polymer in the second layer is allowed to drain from the mold. Preferably, the mold is rotated during and / or after the draining step to ensure uniform polymer distribution.

[0055] In the context of this invention, the coagulant is an aqueous or alcoholic solution of an electrolyte. Suitable electrolytes include formic acid, acetic acid, calcium chloride, calcium nitrate, zinc chloride, or mixtures of two or more of these. Methanol is typically used to provide the alcoholic solution, but other alcohols are also suitable, such as isopropanol and ethanol. The coagulant can have an electrolyte concentration (strength) of 5% to 15% by weight.

[0056] Fluid polymer materials can be cured by solidifying them. A coagulant can be applied to the fluid polymer material to cure it, thereby forming a second layer. The coagulant can be applied to the second layer and then dried (e.g., by applying heat and optionally rotating).

[0057] Fluid polymer materials can be cured by applying heat. Curing can include curing fluid polymer materials, for example, by applying heat.

[0058] Fluid polymer materials can be plastisols. Plastisols are suspensions of plastic particles (e.g., PVC particles) in a liquid plasticizer. When heated (e.g., to about 177°C), the particles and plasticizer dissolve in each other. Upon cooling (e.g., to below 60°C), a flexible, permanently plasticized solid product is obtained.

[0059] Heat can be applied in an oven, which may be equipped with one or more fans that distribute the heat evenly throughout the oven. Heating can also be achieved by directing hot air onto a second layer.

[0060] The viscosity of fluid polymer materials can be adjusted to ensure their penetration into the lining gaps. For example, the viscosity can be reduced compared to conventional support gloves.

[0061] Viscosity can be measured using an RVDV-E Brookfield Viscometer with rotor #1, and the rotation speed (e.g., 2 RPM) and measurement temperature (e.g., 30 to 32°C) should be noted.

[0062] When using an RVDV-E type Brinell viscometer, rotor No. 1, 2 RPM speed, and 30-32℃, the viscosity of the fluid polymer material can be no greater than 10 Pa·s (= 10 Ns / m). 2 = 100 poise), not greater than 5 Pa·s or not greater than 2 Pa·s.

[0063] When using an RVDV-E type Brinell viscometer, rotor No. 1, 2 RPM speed, and 30-32℃, the viscosity of the fluid polymer material can be 1 to 2 Pa·s.

[0064] lining The lining is made of yarn defined according to denier (D). Denier is the weight of 9,000 meters of yarn, expressed in grams. A lower denier corresponds to a lighter yarn per unit length.

[0065] Specifically, the lining yarn has a weight per unit length of 10 to 60 denier. The yarn can have a weight per unit length of 10 to 55 denier, preferably 10 to 50 denier, or 10 to 45 denier, such as 10 to 42 denier, or 10 to 40 denier. The yarn can have a weight per unit length of 15 to 60 denier, such as 20 to 60 denier, preferably 25 to 60 denier, or 30 to 60 denier, such as 35 to 60 denier, or 38 to 60 denier. The weight per unit length of the yarn can be 25 to 50 denier, such as 35 to 45 denier, or 38 to 42 denier.

[0066] Linings are defined based on their weight per unit area in the garment material or its area. Specifically, linings have a weight of 5 to 35 g / m² in the garment material or its area. 2 (50 to 350 g / m 2 The weight per unit area of ​​the lining. The lining may have 10 g / m² in the garment material or its area. 2 Or larger, preferably 15 g / m 2 Or even higher, for example, 18 g / m 2 Or larger, or 19 g / m 2 Or larger, or 20 g / m 2 Or a greater weight per unit area. Linings can have 30 g / m² in the garment material or in areas thereof. 2 Or smaller, preferably 27 g / m 2 Or even smaller, for example, 24 g / m 2 Or smaller, or 23 g / m 2 Or smaller, or 22 g / m 2 Or even smaller weight per unit area. Linings can have 15 to 27 g / m² in the garment material or its area. 2 For example, 18 to 24 g / m 2 or 20 to 22 g / m 2 Weight per unit area.

[0067] The lining yarn can have a unit length weight of 25 to 50 denier, wherein the lining has a weight of 15 to 27 g / m² in the garment material or its area. 2 The weight per unit area. For example, the yarn for the lining can have a weight per unit length of 38 to 42 denier, wherein the lining has 20 to 22 g / m² in the garment material or its area. 2 Weight per unit area.

[0068] When the garment is a glove, the lining may have a density of 5 to 35 g / m² in the palm and / or finger areas. 2 (50 to 350 g / m 2 The weight per unit area of ​​the lining of the glove can be 10 g / m². 2 Or larger, preferably 15 g / m 2 Or even higher, for example, 18 g / m 2 Or larger, or 19 g / m 2 Or larger, or 20 g / m 2 Or even greater weight per unit area. The palm and / or finger area of ​​the lining in the glove can have 30 g / m². 2 Or smaller, preferably 27 g / m 2 Or even smaller, for example, 24g / m 2 Or smaller, or 23 g / m 2 Or smaller, or 22 g / m 2 Or even smaller weight per unit area. The palm and / or finger area of ​​the lining in the glove can have 15 to 27 g / m². 2 For example, 18 to 24 g / m 2 or 20 to 22 g / m 2 Weight per unit area.

[0069] The liner can be similar to that used in conventional support gloves, but is significantly lighter. Surprisingly, the present invention can use a significantly lighter liner and achieve the benefits of enhanced cut resistance, tear resistance, and abrasion resistance, while maintaining dexterity similar to that of conventional single-use disposable gloves. This specific combination of benefits achieved by the present invention has not been previously realized.

[0070] The total weight of the lining in garments (such as gloves) made of clothing materials can be 1.0 g or more, or 1.5 g or more, for example 2.0 g or more, for example 2.5 g or more, or 2.8 g or more, for example 3.0 g or more. The total weight of the lining in garments made of clothing materials can be 6.5 g or less, for example 6.0 g or less, or 5.5 g or less, for example 5.0 g or less, for example 4.5 g or less, or 4.0 g or less, for example 3.5 g or less. The total weight of the lining in garments made of clothing materials can be from 1.0 g to 6.5 g, for example 2.0 g to 4.5 g, for example 2.5 g to 4.0 g, or 3.0 g to 3.5 g.

[0071] When the garment is gloves, the lining can have a density of 10 g / m² in the cuff area. 2Or even higher, for example, 15 g / m 2 Or larger, or 20 g / m 2 Or even higher, for example, 25 g / m 2 Or larger, or 30 g / m 2 Or even higher, for example, 33 g / m 2 Or even greater weight per unit area. The lining can have 60 g / m² in the cuff area. 2 Or even smaller, for example, 50 g / m 2 Or smaller, or 45 g / m 2 Or even smaller, for example, 40 g / m 2 Or smaller, or 37 g / m 2 Or even smaller, for example, 35 g / m 2 Or even less weight per unit area. The lining can have 10 to 60 g / m² in the cuff area. 2 For example, 20 to 50 g / m 2 or 30 to 37 g / m 2 Weight per unit area.

[0072] A liner is applied to a first layer, which is a molded polymer. When the liner is applied, the first layer is solid (not fluid) to facilitate the "dressing" of the liner. In an embodiment, the first layer is obtained by completely drying the polymer material.

[0073] The lining can be formed by knitting, weaving, or some other known processes. The lining has gaps running through it and can be thought of as a mesh. It should be understood that the lining will take the shape of the first layer.

[0074] Preferably, the lining is a knitted lining. The gauge of the knitting machine corresponds to the number of needles per inch (2.54 cm) of the knitting machine. The higher the gauge, the lower the density of the lining. The lining can be formed using a knitting machine with a gauge of 19 or greater, such as 20 or greater, for example, 21. The gauge of the knitting machine can be 25 or smaller, such as 23 or smaller, or 22 or smaller. The gauge of the knitting machine can be 19 to 25, preferably 20 to 23, or 20 to 22, and most preferably 21.

[0075] The rows of knitted material correspond to the (horizontal) loop rows produced by all adjacent needles during the same knitting cycle. In the palm and / or cuff areas, the number of rows per inch can be 20 or greater, e.g., 25 or greater, or 30 or greater, e.g., 35 or greater, or 40 or greater, e.g., 43 or greater. Preferably, the number of rows per inch in the palm area is 43 or greater. Preferably, the number of rows per inch in the cuff area is 40 or greater. In the palm and / or cuff areas, the number of rows per inch can be 70 or less, e.g., 65 or less, or 60 or less, e.g., 55 or less, or 50 or less, e.g., 47 or less, or 44 or less. In the palm and / or cuff areas, the number of rows per inch can be 20 to 70, e.g., 35 to 55, or 40 to 50.

[0076] The warp rows of a knitted material correspond to the (vertical) loop rows made by equivalent needles in a continuous knitting cycle. In the palm and / or cuff areas, the number of warp rows per inch can be 10 or greater, such as 15 or greater, or 18 or greater, or 20 or greater, such as 21 or greater. In the palm and / or cuff areas, the number of warp rows per inch can be 40 or less, such as 35 or less, or 30 or less, such as 25 or less, or 24 or less. In the palm and / or cuff areas, the number of warp rows per inch can be 10 to 40, such as 15 to 30, or 18 to 25.

[0077] The yarn is preferably a multi-ply yarn, such as a two-ply to a six-ply yarn. Most preferably, the yarn is a two-ply yarn. Each filament may contain two or more filaments, such as four or more filaments, preferably eight or more filaments, such as ten or more, or eleven or more, and most preferably twelve filaments. Each filament may contain 20 or fewer filaments, such as fifteen or fewer, or thirteen or fewer. Each filament may contain 2 to 20 filaments, such as eight to 15 filaments. The yarn may contain two to four plies, particularly two plies, wherein each ply contains two or more filaments, such as four or more filaments, preferably eight or more filaments, such as ten or more, or eleven or more, and most preferably twelve filaments. The yarn may contain a total of two or more filaments, such as six or more, or ten or more, or fourteen or more, preferably eighteen or more, such as twenty or more, or twenty-two or more, or twenty-three or more, most preferably twenty-four filaments. The yarn may contain 40 or fewer filaments.

[0078] The lining is formed of yarn and can be made of a variety of yarn materials, such as one or a mixture of two or more of the following: cotton, nylon (polyamide), elastic fibers (also known as Spandex™ or Lycra™), polyester (including CoolMax™), aramid (including Technora® and para-aramid, such as Kevlar® and Twaron®), polyethylene (including ultra-high molecular weight polyethylene available under the trade names Dyneema® and Spectra®), glass fiber, acrylic, carbon (conductive) fiber, copper (conductive) fiber, thunderon™ conductive fiber (copper sulfide chemically bonded to acrylic and nylon fibers), high-strength liquid crystal polyester (including multifilament yarns spun from liquid crystal polymers available under the trade name Vectran™), and polyolefin fibers (including Viafil®). Preferably, the yarn is nylon, such as nylon 6 (polycaprolactam).

[0079] Clothing (such as gloves) may be expected to be cut- and tear-resistant to protect the wearer. When cut resistance is required, supportive gloves can be manufactured with a lining made of special cut-resistant yarn. However, such cut-resistant yarns are expensive compared to nylon and cotton yarns. Furthermore, in some cases, they may still be difficult to withstand chemical corrosion.

[0080] Protective gloves may be expected to be cut- and tear-resistant, liquid-impermeable, and chemically resistant to protect the wearer's hands. However, it is also desirable for such gloves to be lightweight and flexible so as not to impede the wearer's dexterity, and to have an outer surface that provides good grip between the glove and the object being handled. A comfortable glove is also desirable, so that the wearer is less inclined to remove it in hazardous environments, for example, by improving its sweat-wicking or absorbent properties.

[0081] The lining may include cut-resistant fibers. In the context of this invention, a "cut-resistant lining" is a lining formed of yarns containing cut-resistant fibers. When a cut-resistant lining is used, the resulting garment material has greater cut resistance than a garment material with, for example, the same weight per unit area lining but without cut-resistant fibers.

[0082] Suitable cut-resistant fibers include one or more of aramid (including para-aramid), ultra-high molecular weight polyethylene (UHMWPE, such as Dyneema®), high-strength polypropylene, high-strength polyvinyl alcohol, high-strength liquid crystal polyester, and glass fiber. In embodiments, the lining comprises ultra-high molecular weight polyethylene and / or glass fiber. The lining may comprise cut-resistant fibers and conventional fibers. The yarn may comprise (i) at least one of aramid, UHMWPE, glass fiber, carbon fiber, copper fiber, and high-strength liquid crystal polyester and / or (ii) at least one of cotton, nylon, elastic fiber, polyester, and acrylic. The yarn may comprise 30% by weight or more, for example 50% by weight or more, or 60% by weight or more of fiber (i), and 70% by weight or less, for example 50% by weight or less, or 30% by weight or less of fiber (ii). The yarn may comprise UHMWPE and nylon.

[0083] It should be understood that linings are typically stretched on the first layer (which can be mounted on a mold). Therefore, an unstretched lining, such as a knitted lining, will have a greater weight per unit area than a stretched lining. Stretched linings provide a more open construction, meaning the gaps in the substrate are enlarged.

[0084] Linings can be in the form of sheets. In this case, garments or garment parts are produced by further processing the garment material sheet, for example, by cutting pieces from the garment material sheet and then using said pieces to manufacture the garment. Linings can also be in the form of a part of a garment, such as a pocket on an overcoat or a finger cot on a glove.

[0085] The lining is preferably in the form of a complete garment, such as gloves, boots, shoes, or socks. This means that the garment can be obtained directly, rather than having to piece together pieces of lining or garment material. Such garments can be seamless.

[0086] The method of the present invention provides a garment material in which a lining is embedded in a polymer, i.e., the lining is completely coated or encapsulated by a solid polymer material. This is achieved by applying (“dressing”) the lining to a first layer, coating the lining with a fluid polymer material, and then applying a textile layer. The inventors have determined that “clamping” the lining within the garment material provides improved properties.

[0087] It is believed that fluid polymer materials clog the gaps in the knitted yarns, thus "locking" the lining in place. Therefore, fluid polymer materials can be considered "adhesive" compounds. This strengthens the garment material to provide strength and cut resistance. This reinforcement can be provided while maintaining flexibility.

[0088] In conventional support gloves, the liner is first fitted onto a mold, and the subsequent coating only partially penetrates the liner; the liner is coated with polymer material only on one side, and therefore is not “embedded” as defined in the context of this invention.

[0089] Because the lining is worn in close contact with the skin, it is desirable to minimize the amount that permeates into the gaps. Therefore, if the polymer material soaks through the lining, it means direct contact between the polymer and the skin. This can lead to irritation and sweat buildup near the skin, and in particular, some wearers may be allergic to PU.

[0090] Specifically, it should be understood that this invention differs from the disclosure of WO2010 / 022024. In WO2010 / 022024, the knitted lining is integrally bonded to the latex shell to provide a rough outer texture with excellent grip properties. The lining is not "embedded" within the material as in this invention. Furthermore, if an electrostatic flocking coating is applied to the gloves of WO2010 / 022024, it is applied to the skin-contact surface of the garment (not the outer surface providing grip).

[0092] Third layer and subsequent layers Preferably, the clothing material consists essentially of a first layer, a second layer, and a textile layer, or consists of a first layer, a second layer, and a textile layer. Preferably, the clothing material does not contain any other polymer layers or any other layers besides the first layer, the second layer, and the textile layer.

[0093] Clothing materials may include additional layers (i.e., third and subsequent layers) comprising polymeric material. These additional layers may be applied to the second layer in the form of a fluid polymeric material, and the fluid polymeric material may be cured to form the third (or subsequent) layer. This can be repeated to construct a desired number of additional layers. For example, the method may additionally include applying a fluid polymeric material to the third layer and curing the fluid polymeric material to form a fourth layer. Typically, the method may include applying a fluid polymeric material to the nth layer and curing the fluid polymeric material to form a (n+1)th layer, where n is equal to or greater than 2. Clothing materials and / or garments may include a (n+1)th layer, which is a molded polymer disposed at one or more locations on the nth layer, the (n+1)th layer exhibiting the shape of the nth layer at said one or more locations, where n is equal to or greater than 2, such as 2, 3, or 4.

[0094] The fluid polymer material may be the same as or different from the polymer material used in the first and / or second layers. The third (and subsequent) layers may be constructed in a conventional manner by immersion / soaking in a bath containing a solution or suspension of polymer material. The third or subsequent layer may be a molded polymer disposed at one or more locations on the second layer, wherein the third or subsequent layer takes on the shape of the second layer at said one or more locations.

[0095] The third or subsequent layers may comprise a foamed polymer material, for example, as described in WO2005 / 088005. The foamed fluid polymer material may be applied to the nth layer, and the fluid foamed polymer material may be cured to form the (n+1)th layer, where n is equal to or greater than 2. The outer layers of the foamed polymer material may be removed, thereby giving the surface of the polymer material an open, porous structure.

[0096] The third layer (and subsequent layers) can be constructed using a coagulant. The coagulant is an aqueous or alcoholic solution of an electrolyte that can be applied prior to the fluid polymer material. Suitable electrolytes include formic acid, acetic acid, calcium chloride, calcium nitrate, zinc chloride, or mixtures of two or more of these. Methanol is typically used to provide the alcoholic solution, but other alcohols are also suitable, such as isopropanol and ethanol. In the examples, the coagulant has an electrolyte concentration (strength) of 5% to 15% by weight.

[0097] In one embodiment, the method further includes applying a coagulant to a second (or subsequent) layer, for example, by immersion in a coagulant. The third (and subsequent) layer may be constructed using a plastisol.

[0098] Textile layer The textile layer is a skin-contact layer that makes the material more comfortable for the user or wearer. The textile layer is preferably the outermost layer of the clothing material. The textile layer can be disposed on a third or subsequent layer. Preferably, the textile layer is disposed on a second layer. The textile layer can be disposed at one or more locations on the underlying (e.g., second, third, or subsequent) layers, and at said one or more locations, it takes the shape of the underlying layer.

[0099] In the case of gloves, the textile layer typically forms the inner surface of the glove. The use of fibers is particularly useful in the final layer to be applied to the mold, as it can provide the feel of a textile lining. Such a layer is comfortable against the skin and can be considered a skin-comfort layer.

[0100] The textile layer can be a woven or nonwoven material, such as a fabric. The textile layer preferably includes or is composed of flocking, and the textile layer can be referred to as a flocked lining. The textile layer can be formed by applying fibers (e.g., flocking) to a second layer. Alternatively, in the presence of a third (or subsequent) layer, the textile layer can be formed by applying fibers (e.g., flocking) to a third or subsequent layer.

[0101] The fibers can be selected from the list of the following: cotton, rayon, aramid, polyamide (e.g., nylon), polyester, carbon, glass, polyacrylonitrile, polypropylene, and combinations thereof. Preferably, the fibers comprise or consist of cotton or nylon fleece.

[0102] The bulk density of the fiber (e.g., nylon fleece) can be 200 g / l or less, for example, 150 g / l or less, such as 120 g / l or less. The bulk density can be 50 g / l or greater, for example, 50 g / l to 200 g / l. The fiber (e.g., nylon fleece) can have a fiber length of 1.0 mm or less, for example, 0.7 mm or less. The fiber length can be 0.1 mm or greater, or 0.3 mm or greater, for example, 0.1 mm to 1.0 mm, or 0.3 mm to 0.7 mm. The fiber can have a unit length weight of 0.1 to 10 denier, for example, 0.1 to 5 denier, or 0.1 to 2.0 denier. The fiber can have a unit length weight of 0.5 to 10 denier, for example, 1.0 to 10 denier, preferably 0.2 to 10 denier. The unit length weight of the fiber can be 0.5 to 5 denier, for example, 1.0 to 2.0 denier.

[0103] The fibers can be applied in the form of woven or nonwoven materials, such as fabrics. The fibers are preferably applied by flocking. Flocking is the process of depositing numerous small fiber particles (called flock) onto a surface. Preferably, flocking is applied by electrostatic flocking, whereby a high-voltage electric field is used to attract the flock to the surface of the glove. Typically, the flock is given a negative charge while the substrate is grounded. Flocking can also be achieved by blowing air.

[0104] In one embodiment, a fluid polymer material having fibers suspended therein is applied, and the fluid polymer material is cured to form a textile layer having fibers therein. Therefore, the textile layer can be a molded polymer having fibers therein. Thus, clothing can include a textile layer as an inner layer, which is a molded polymer having fibers (e.g., nylon fleece) therein.

[0105] In one embodiment, the fluid polymer material comprises 5% or more, or 10% or more, or 15% or more, such as 20% or more fibers (e.g., nylon fleece) on a dry weight basis.

[0106] mold Clothing materials can be made by a method that includes providing a first layer, which is a molded polymer assembled (e.g., mounted) on a mold.

[0107] Preferably, the mold is in the shape of a person's right or left hand. Glove production can utilize one or more right-hand-shaped molds and one or more left-hand-shaped molds. Therefore, the mold and the resulting glove can be anatomically designed hand molds. Producing gloves molded to fit each of the wearer's hands (rather than ambidextrous gloves) allows for a closer fit to the wearer's hand. This reduces the amount of wrinkles the glove has on the wearer's hand, increasing comfort and dexterity compared to similar but ambidextrous gloves. Using anatomically designed gloves reduces the risk of the glove getting stuck in the machine, thus reducing the risk of hand injury to the wearer during use.

[0108] Those skilled in the art will understand that the first layer can be prepared by curing a fluid polymer material into a given shape, for example, by using a mold. The mold can be made of metal, ceramic (e.g., porcelain), glass fiber, and / or plastic.

[0109] The fluid polymer material can be additionally applied to the mold, and the fluid polymer material can solidify to form a molded polymer. A coagulant (as defined above) can be applied to the mold prior to the fluid polymer material. The coagulant helps the fluid polymer material solidify on the mold.

[0110] The molding polymer can be removed from the mold before the liner is applied. However, it is preferable that the molding polymer remains on the mold while the liner is applied. In this way, the mold can support the molding polymer, even if it is very thin. The molding polymer with the liner applied to it can remain on the mold while the fluid polymer material is applied and solidifies.

[0111] Clothing material (or garment or garment part) can be removed from a mold. After the clothing material is made, it is usually peeled (removed) from the mold. When the clothing material is removed from the mold, it can be turned over so that the first layer becomes the outer surface.

[0112] The surface of the mold will be reflected in the surface of the first layer. Therefore, if the mold has a smooth outer surface, the fluid polymer material in contact with said smooth surface will solidify to form a first layer with a smooth surface. Similarly, if the mold has a textured or “rough” surface, the first layer will also have a textured surface. Having a range of textures in clothing can be beneficial. For example, a mold with a gritty surface can be used to provide clothing materials with good grip properties. In one embodiment, the clothing is a glove, wherein the glove has a palm and fingers, and the outer surface has a texture (e.g., gritty) at the palm and / or one or more fingers.

[0113] Therefore, this invention allows the surface of the first layer to be customized according to the desired application. In conventional support gloves, the lining is applied to a mold, so the mold does not impart significant texture to the resulting garment.

[0114] Some or all of the outer surface of the mold may have a texture (e.g., uneven or rough). In an embodiment, the mold has the shape of a glove, wherein the glove has a palm and fingers, and the outer surface has a texture (e.g., gravelly) at the palm and / or at one or more fingers.

[0115] The mold can have the shape of a complete garment, such as a glove (hand shape), sock, or boot (foot shape), or the mold can have the shape of a portion of a garment. If a sheet of garment material is required, a mold with a flat surface can be used. The mold can have the shape of a complete garment (e.g., a glove), and the method may include the additional step of removing the garment from the mold by turning it inside out.

[0116] Detailed description of the attached figures Embodiments of the invention will now be described by way of example with reference to the accompanying drawings, wherein: Figure 1 These are three photos of hands covered by chemically resistant gloves using existing technology; Figure 2 These are two photos comparing single-use disposable gloves; Figure 3 These are two photographs of the gloves of the present invention; and Figure 4 It is a cross-sectional view depicting the layers in clothing materials.

[0117] The attached diagram Figure 1 Three images are shown of a hand covered by a prior art chemically resistant glove 10.

[0118] The left-hand image shows a hand covered by glove 10, in a relaxed, open position. The finger area 12, palm area 14, and cuff area 16 are clearly distinguishable. The thickness of the garment material in palm area 14 is 1.1 mm. The left-hand image shows that due to the lack of flexibility in the garment material, wide wavy patterns form where the material wrinkles.

[0119] The central image shows a hand wearing gloves 10, with five fingers (including the thumb) in a pinched position. The broad wavy folds on the palm area 14 are intensified by the contraction of the palm, and the broad wavy folds are visible in the clothing material covering the thumb.

[0120] The right-hand image shows a hand wearing glove 10, clenched into a fist. Due to the wide, wavy wrinkles caused by the lack of flexibility in the material, the user must exert considerable force to clench the hand into a fist when wearing glove 10. Because of the lack of flexibility in the clothing material, very few wrinkles are visible on the outer surface of glove 10 in this image.

[0121] The study found that gloves 10 significantly reduced the wearer's dexterity and comfort.

[0122] The attached diagram Figure 2 The back (palm side) and front (palm side) of a single-use disposable glove 20 (Ansell Microflex) are shown in comparison (left image).

[0123] The image shows a hand covered by glove 20, in a relaxed, open position. The finger area 22, palm area 24, and cuff area 26 are clearly distinguishable.

[0124] like Figure 2 As shown, the single-use disposable glove 20 produces obvious wrinkles on the wearer's hands, which reduces the wearer's dexterity and comfort.

[0125] The attached diagram Figure 3 The back (palm side) (left hand image) and front (palm side) (right hand image) of the glove 30 of the present invention are shown, the glove being... Figure 2 The gloves shown are the same size and are worn on the same wearer's hands.

[0126] The image shows a hand covered by glove 30, in a relaxed, open position. The finger area 32, palm area 34, and cuff area 36 are clearly distinguishable.

[0127] The thickness of the clothing material in the palm area 34 is 0.5 mm. Compared with the comparative glove 20, the glove 30 of the present invention is more adaptable to changes in the shape of the wearer's hand.

[0128] The gloves 30 of the present invention do not wrinkle on the wearer's hands.

[0129] The glove 30 of the present invention does not significantly reduce the wearer’s dexterity and provides a significantly higher level of dexterity and comfort compared to comparative gloves 10 and 20.

[0130] Example Clothing material manufacturing In the first step, dies are mounted in rows on bars called "flight bars." In this example, each die has the shape of a complete garment, in this case, a glove. The dies can be made of, for example, metal, ceramic, fiberglass, or plastic. The gloves are schematically drawn (as mittens), but will actually have the shape of a hand. The light bars move linearly from one processing station to another at a set speed. Of course, the set speed of the light bars can be varied, and there can be several light bars, each at a different stage of the process.

[0131] A coagulant is applied to the mold. This is done by immersing the mold in a bath or tank containing the coagulant, but it can also be done by spraying the coagulant onto the mold. The coagulant is an aqueous or alcoholic solution of an electrolyte. Calcium nitrate is used as the electrolyte in this example. The mold is then removed from the bath / tank and may be heated to evaporate any excess coagulant, followed by cooling to allow the coagulant to dry.

[0132] The first polymer material is applied to a mold by immersion in a bath or tank containing the first polymer material. In this example, the first polymer material comprises a synthetic latex. The mold is then removed and can be rotated to drain and evaporate excess first polymer material. This step forms the first sublayer of the first layer.

[0133] The coagulant is applied to the mold again in essentially the same manner as described above. The coagulant is an aqueous or alcoholic solution of an electrolyte. Calcium nitrate is used as the electrolyte in this example. The mold is then removed from the bath / tank and may be heated to evaporate any excess coagulant, followed by cooling to allow the coagulant to dry.

[0134] The second polymer material is applied to a mold by immersion in a bathtub or tank containing the second polymer material. In this example, the second polymer material comprises a synthetic latex. The mold is then removed and can be rotated to drain and evaporate excess second polymer material. This step forms the second sublayer of the first layer. In this example, the first layer is now complete. The total thickness of the first layer (including both the first and second polymer materials) is 0.08–0.19 mm.

[0135] The second sub-layer of latex is impregnated by immersing the mold in hot water. The mold is then dried.

[0136] The lightweight knitted lining is dressed onto a mold that has already been coated with the first layer. The lining is made of 40-denier nylon 6 white yarn, consisting of two strands, each with 12 filaments, and knitted on a No. 21 knitting machine. The lining has a unit area weight of 20-22 g / m² in the palm area. 2 The weight per unit area in the cuff area is 33-35 g / m². 2 In conventional processes, the liner is directly fitted onto the mold. However, in this invention, the liner is fitted onto the first layer of polymer coating.

[0137] The mold supporting the lining is immersed in a bathtub / trough containing a third polymer material, and then removed to drain excess polymer material. The lining is coated with the third polymer material, which seals the gaps in the lining and thus embeds the inner lining. The third polymer material comprises a mixture of NBR, neoprene rubber, and acrylic latex, which can be considered an adhesive compound. The third polymer material and the lining define the second layer. The total thickness of the second layer (including the lining embedded in the third polymer material) is 0.20–0.25 mm.

[0138] The mold now supports the liner sandwiched between the first and second layers. The mold is drained and rotated to remove excess third polymer material.

[0139] Nylon flocking was applied to the mold using electrostatic coating. The flocking linear density was 1.53 denier, and the fiber length was 0.5 mm. The flocking was fixed, and the second polymer material was dried and cured using standard procedures. The gloves were peeled off the mold, then washed and dried.

[0140] The attached diagram Figure 4A cross-sectional view depicting layers in garment material 40 forming gloves manufactured by the above-described process is shown. Garment material 40 has an outer layer 42 of synthetic latex. The outer surface of layer 42 also has a texture due to the texture on the mold. The garment material also has a second latex layer 44 in direct contact with the outer layer 42. Layers 42 and 44 constitute the first layer of the garment material of the present invention. A lining 48 is embedded in an adhesive compound 46. The lining 48 constitutes the second layer of the garment material of the present invention, and it is in direct contact with layer 44 of the first layer of the garment material of the present invention. A flocking coating 410 corresponds to the textile layer of the garment material of the present invention and is in direct contact with the second layer of the garment material of the present invention.

[0141] Dexterity performance - pin diameter The dexterity achievable when wearing the gloves of this invention is determined according to Clause 5.2 of ISO 21420:2020. The minimum pin diameter detected through the gloves is the optimal value (5 mm) achievable under the testing apparatus, thus the gloves achieve the maximum dexterity level (level 5).

[0142] The dexterity of the wearer when wearing gloves made of the clothing material of the present invention was compared with the dexterity of the same wearer when wearing (i) comparative chemical-resistant gloves and (ii) comparative single-use disposable NBR gloves. Under the above tests, the comparative gloves also achieved a level 5 dexterity. Compared with the requirements of the clothing material of the present invention, the lining of the comparative chemical-resistant gloves has heavier yarns and a greater weight per unit area.

[0143] The gloves of this invention provide the wearer with a significantly higher level of dexterity than comparative chemical-resistant gloves.

[0144] The level of dexterity achieved with the gloves of this invention is similar to that achieved with conventional single-use disposable gloves.

[0145] Dexterity Performance - O'Connor Finger Dexterity Test O'Connor finger dexterity tests were performed on bare hands (control), the gloves of the present invention (MaxiDex Elite), and comparative chemical-resistant gloves (MaxiChem, as disclosed in WO 2019 / 229427 A1). Gloves in sizes 8, 9, and 10 were used, and both the left and right hands were examined separately. The O'Connor finger dexterity device (Lafayette Instrument Company, model 32021) was used according to the following procedure: 1) Before testing, place the nail board in front of the operator and sit comfortably in a chair.

[0146] 2) Pick up three pins at a time and fill the holes, placing the three pins in each hole as quickly as possible with only one hand.

[0147] 3) Starting from the corner furthest from the dominant hand, fill each row completely before moving to the next row, without skipping any.

[0148] 4) Record the time spent filling the first fifty holes and the last fifty holes respectively.

[0149] 5) Calculate the raw score using the following formula:

[0150] The reduction in dexterity was calculated as a percentage relative to the bare hand. These results are shown in the table below.

[0151]

[0152] According to the test, the dexterity reduction percentage of the comparison glove was as high as 69.0%. However, according to the test, the maximum dexterity reduction percentage of the glove of the present invention was only 28.2%.

[0153] This demonstrates that, compared to the comparative chemical-resistant gloves disclosed in WO 2019 / 229427 A1, the gloves of the present invention provide significantly better finger dexterity.

[0154] Dexterity Performance - Purdue Pegboard Test The experiment compared bare hands (control), the gloves of the present invention (MaxiDex Elite), and comparative chemical-resistant gloves (MaxiChem, as disclosed in WO 2019 / 229427 A1). Purdue Nailboard Test. Use size 8, 9, and 10 gloves and test the left and right hands separately. Purdue Nailboard (Lafield Instruments Model 32020) Use according to the following procedure: 1) Before testing, place the nail board in front of the operator and sit comfortably in a chair.

[0155] 2) In the first sub-test, the subject first used the preferred hand, then the non-preferred hand, and finally both hands to place the pin in the hole as far as possible within a 30-second time period, and the value was recorded.

[0156] 3) In the fourth subtest, the subject used both hands alternately to construct an “assembly” (pin + washer + collar + washer) over a 60-second period and recorded the values.

[0157] The reduction in dexterity was calculated as a percentage relative to the bare hand. These results are shown in the table below.

[0158]

[0159] This demonstrates that, compared to the comparative chemical-resistant gloves disclosed in WO 2019 / 229427 A1, the gloves of the present invention provide significantly better finger and hand dexterity.

[0160] Dexterity performance - Groove nail plate test O'Connor finger dexterity tests were performed on bare hands (control), the gloves of the present invention (MaxiDex Elite), and comparative chemical resistance gloves (MaxiChem, as disclosed in WO 2019 / 229427 A1). Gloves in sizes 8, 9, and 10 were used, and both the left and right hands were examined separately. A grooved pegboard (Lafield Instruments model 32025) was used according to the following procedure: 1) Before testing, place the nail board in front of the operator and sit comfortably in a chair.

[0161] 2) Fill the rows by using studs without skipping holes, first test the dominant hand, and start filling the holes from the farthest side.

[0162] 3) Measure the time taken to complete the task.
