In addition, the present invention is applied to a human body joint part, and stretching by means of the lugs can be achieved during movement of the human body joint without hindering the joint movement, so that any puncture-resistant material having no elasticity or very limited elasticity can be used at a position having a high flexibility requirement for human body movement.

Description

A stab-resistant fabric structure and stab-resistant gloves that combine comfort and stab resistance Technical Field

[0001] This invention relates to a stab-resistant fabric structure that combines comfort and stab resistance, and also to stab-resistant gloves made using the stab-resistant fabric structure. Background Technology

[0002] For protective equipment such as stab-resistant gloves and vests, the ability to prevent punctures by sharp objects is crucial. Existing stab-resistant materials used in protective equipment often have very limited elasticity. This is because excessive elasticity causes the pores in the material to deform and expand, allowing sharp objects such as needles to easily penetrate. However, applying stab-resistant materials with very limited elasticity to human joints hinders joint movement, thereby reducing joint flexibility and significantly decreasing human comfort.

[0003] The stab-resistant fabric structure used in existing protective equipment consists of an inner layer, a stab-resistant layer, and an outer layer sewn together along their edges. When joints move, they will inevitably pull on the stab-resistant layer, and the stab-resistant layer, due to its limited elasticity, will hinder the pulling, thus restricting the movement of the joints.

[0004] To address the aforementioned issues, existing methods involve sewing the outer and inner layers together and then reducing the size of the intermediate puncture-resistant layer, sandwiching it between the outer and inner layers. Since there is no fixing between the puncture-resistant layer and either the outer or inner layer, it can slide between the two layers, thus not hindering joint movement and improving comfort. However, this method has the following drawbacks:

[0005] (1) The puncture-resistant layer may slide during use, which may pose a risk to its protective performance.

[0006] (2) The puncture-resistant layer may curl, which may pose a risk to the protective performance and reduce human comfort. Summary of the Invention

[0007] The first objective of this invention is to provide a puncture-resistant fabric structure that is simple in structure, low in cost, and improves the flexibility of human joint movements and thus enhances human comfort while having good puncture resistance.

[0008] The first objective of this invention is achieved through the following technical measures: a stab-resistant fabric structure that combines comfort and stab resistance, comprising an inner layer, an outer layer, and a stab-resistant layer between the two, wherein the edges of the inner layer and the outer layer are connected together, characterized in that the stab-resistant layer comprises a body and a plurality of lugs disposed on at least a portion of the edge of the body, the portion being referred to as a connecting area, wherein the lugs are fixed together with the connecting portions of the inner layer and the outer layer, and the edge of the body located in the connecting area is not connected to the inner layer and the outer layer.

[0009] The stab-resistant layer of this invention is locally fixed by connecting the inner and outer layers with lugs. During use, the stab-resistant layer remains in a predetermined position without slipping, preventing it from rolling inward and ensuring reliable needle-proof protection. Furthermore, when applied to human joints, the lugs allow for stretching without hindering joint movement. Therefore, any inelastic or very inelastic stab-resistant material can be used in areas requiring high flexibility, such as the back of the hand and knuckles of gloves, and the elbow joint of stab-resistant vests, meeting the requirements for joint flexibility, including flexion. For example, in the production of 360-degree all-around cut and stab-resistant gloves, it is necessary to use non-elastic or very elastic stab-resistant materials on the entire palm and back of the hand. In addition, when the present invention is applied to protective equipment, two pieces of stab-resistant fabric are sewn together. Since the stab-resistant layer of each piece of stab-resistant fabric is sewn together with the inner and outer layers through lugs, the main body of the stab-resistant layers of the two pieces of stab-resistant fabric are spliced ​​together. Compared with the existing stab-resistant fabrics where the inner layer, stab-resistant layer and outer layer are sewn together along the three edges, the present invention reduces the thickness after the two pieces of stab-resistant fabric are spliced ​​together, thus improving comfort.

[0010] When two identical stab-resistant fabric structures are joined and sewn together, the two stab-resistant fabric structures are connected in the connection area by sewing the inner layer, outer layer and lug together. In the connection area, the body edge of the stab-resistant layer is not connected to the inner and outer layers. Outside the connection area, all the body edges of the stab-resistant layer are sewn together to the inner and outer layers, or part of the body edges are sewn together to the inner and outer layers, or the body edges are not sewn together to the inner and outer layers.

[0011] The puncture-resistant layer of the present invention consists of two or more layers, with the lugs of each puncture-resistant layer overlapping or staggered.

[0012] The present invention provides at least one first functional layer between the stab-resistant layer and the outer layer, wherein the edge of the first functional layer is fixed together with the connection part of the outer layer and the inner layer, as well as the connection part of the outer layer, the inner layer and the stab-resistant layer lug.

[0013] The present invention provides at least one second functional layer between the puncture-resistant layer and the inner layer, and the edge of the second functional layer is fixed together with the connection parts of the outer layer, the inner layer, the edge of the first functional layer, the outer layer, the inner layer, the puncture-resistant layer lug, and the edge of the first functional layer.

[0014] The present invention provides at least one second functional layer between the stab-resistant layer and the inner layer. The second functional layer includes a body and a plurality of lugs on the edge of the body. The lugs of the second functional layer are fixed together with the connecting parts of the inner layer, the outer layer, and the edge of the first functional layer. The lugs of the second functional layer overlap or are offset from the lugs of the stab-resistant layer. There is no connection between the body of the second functional layer and the inner layer, the outer layer, the lugs of the stab-resistant layer, and the edge of the first functional layer.

[0015] The present invention provides at least one first functional layer between the stab-resistant layer and the outer layer. The first functional layer includes a body and a plurality of lugs provided on the edge of the body. The lugs of the first functional layer are fixed together with the connection parts of the inner layer and the outer layer. The lugs of the first functional layer overlap or are offset from the lugs of the stab-resistant layer. There is no connection between the body of the first functional layer and the lugs of the inner layer, the outer layer, and the stab-resistant layer.

[0016] The present invention provides at least one second functional layer between the puncture-resistant layer and the inner layer, and the edge of the second functional layer is fixed together with the connection part of the outer layer and the inner layer.

[0017] The present invention provides at least one second functional layer between the stab-resistant layer and the inner layer. The second functional layer includes a body and a plurality of lugs on the edge of the body. The lugs of the second functional layer are fixed together with the connecting parts of the inner layer and the outer layer. The lugs of the second functional layer overlap or are offset from the lugs of the stab-resistant layer and the lugs of the first functional layer. There is no connection between the body of the second functional layer and the inner layer, the outer layer, the lugs of the stab-resistant layer, and the lugs of the first functional layer.

[0018] The layers of this invention are connected by sewing, specifically using a computerized pattern sewing machine. The presser foot of the machine is a hollow circle with a diameter of 2.5–3 mm, and the needle is positioned at the center of the circle. The distance between the edge of each layer and the seam is 2–2.5 mm. When the distance is 3–3.5 mm, it ensures that the stitching is not exposed when the piece is turned inside out. If the distance exceeds 3.5 mm, the excess material after turning inside out will cause the material to feel rough and uncomfortable to the touch.

[0019] The length of the lug described in this invention is 4-5 mm, and the width is 5-10 mm.

[0020] The body and the lugs described in this invention are integrally made of the same puncture-resistant material.

[0021] The stab-resistant layer of the present invention uses a stab-resistant material with a Young's modulus of 5 to 1000 MPa.

[0022] A second objective of the present invention is to provide a stab-resistant glove made using the above-described stab-resistant fabric structure.

[0023] The second objective of this invention is achieved through the following technical measures: a stab-resistant glove made using the above-mentioned stab-resistant fabric structure, comprising a back of the hand and a palm, wherein the front part of the back of the hand and the palm is a finger part and the back part is a palm part, and the rear end of the palm part is a wrist part, characterized in that both the back of the hand and the palm are made of the stab-resistant fabric structure, and the finger parts and palm parts of the back of the hand and the palm are respectively joined together at the edge position and sewn together to obtain the stab-resistant glove.

[0024] The present invention adds a fingertip extension surface between the back of the hand and the fingers on the palm side. The fingertip extension surface adopts the puncture-resistant fabric structure. The front and rear edges of the fingertip extension surface are sewn together with the edges of the fingers on the back of the hand and the palm side, respectively. One end of the fingertip extension surface extends from the inside of the index finger to the inside of the little finger and to the other end.

[0025] The present invention features a fingertip extension surface, which provides greater space for finger movement. Furthermore, since the anti-puncture layer is connected to the inner and outer layers through lugs, the anti-puncture layer body of the fingertip extension surface can be combined with the anti-puncture layer body of the back and palm of the hand, so that the two anti-puncture layers do not overlap, reducing the thickness after being flipped over and improving comfort. Moreover, the fingertip extension surface can cover the fingertip, reducing the risk to the protective performance.

[0026] The wrist portion of the back and palm sides of the hand described in this invention uses a wrist extension surface, which adopts the puncture-resistant fabric structure. The front edge of the wrist extension surface is sewn together with the rear edge of the palm portion of the back and palm sides of the hand.

[0027] In this invention, the edges of two puncture-resistant fabric structures are sewn together, and the lugs located at the sewn edges of the two puncture-resistant fabric structures are staggered.

[0028] Compared with the prior art, the present invention has the following significant effects:

[0029] (1) The anti-stab layer of the present invention is locally fixed by connecting the lugs and the inner and outer layers. When in use, the anti-stab layer can be in a predetermined position without sliding, and it also prevents the anti-stab layer from rolling inward, which can ensure the reliability of anti-needle puncture. At the same time, the present invention is applied to the joint area of ​​the human body. When the human joint moves, it can be stretched by the lugs without hindering the joint movement. Therefore, any anti-stab material with no elasticity or very limited elasticity can be used in positions where the human body's movement flexibility is required, such as the back of the hand and finger joints of gloves and the elbow joint of anti-stab vests, which can meet the requirements of joint bending and other flexibility.

[0030] (2) When the present invention is applied to protective equipment, two pieces of stab-proof fabric are sewn together. Since the stab-proof layer of each piece of stab-proof fabric is sewn together with the inner and outer layers through the lugs, the stab-proof layers of the two pieces of stab-proof fabric are joined together. Compared with the existing stab-proof fabric where the inner layer, stab-proof layer and outer layer are sewn together along the edges of the three, the present invention reduces the thickness after the two pieces of stab-proof fabric are joined together, thus improving comfort.

[0031] (3) The stab-proof gloves of the present invention are provided with a fingertip extension surface, which can provide more space for finger movement. Moreover, since the stab-proof layer is connected to the inner and outer layers through the lugs, the stab-proof layer body of the fingertip extension surface can be spliced ​​with the stab-proof layer body of the back and palm of the hand, so that the two stab-proof layers do not overlap, reducing the thickness after splicing and improving comfort. In addition, the fingertip extension surface can cover the fingertip, reducing the risk of protection performance.

[0032] (4) The present invention has a simple structure and low cost. While having good anti-puncture performance, it can improve the flexibility of human joint movements, thereby improving human comfort.

[0033] (5) This invention can be applied partially or fully to any protective equipment, is highly practical, and is suitable for widespread promotion and use. Attached Figure Description

[0044] The present invention will be further described below through specific embodiments, but this is not a limitation of the present invention. Those skilled in the art can make various modifications or improvements based on the basic idea of ​​the present invention, but as long as they do not depart from the basic idea of ​​the present invention, they are all within the protection scope of the present invention.

[0045] As shown in Figures 1 to 8, this invention provides a stab-proof glove, comprising a back of the hand 1 and a palm side 2. The front part of the back of the hand 1 and the palm side 2 is the finger part 3, and the back part is the palm part 4. The rear end of the palm part 4 is the wrist part. Both the back of the hand 1 and the palm side 2 are made of a stab-proof fabric structure that combines comfort and stab resistance. The finger part 3 and the palm part 4 of the back of the hand 1 and the palm side 2 are respectively joined together at the edge to form a stab-proof glove.

[0046] The stab-resistant gloves of this invention utilize a stab-resistant fabric structure that combines comfort and stab resistance. It comprises an inner layer 5, an outer layer 7, and a stab-resistant layer 6 located between them. The edges of the inner layer 5 and the outer layer 7 are connected together. The stab-resistant layer 6 primarily provides cut and stab resistance (the stab-resistant fabric also has cut resistance). It can be made of a stab-resistant material with a Young's modulus of 5–1000 MPa, such as plain weave fabric, double-sided cotton knit fabric, or cut- and stab-resistant fabric with internal steel or tungsten wire reinforcement. In this embodiment, the stab-resistant layer 6 is a single layer. The outer layer 7 primarily functions as abrasion-resistant, slip-resistant, flame-retardant, fire-resistant, and protects the stab-resistant layer. The inner layer 5 primarily functions as a skin-friendly absorbent material. The stab-resistant layer 6 consists of a body 61 and several lugs 62 disposed on the edge of the body 61. In this embodiment, the lugs 62 are 4mm long and 5mm wide. The distance between adjacent lugs 62 can be determined according to actual conditions. In this embodiment of the stab-resistant glove, the lugs are distributed across the entire palm surface. In a top view of the palm surface, the lug structures are distributed not only on both sides of each finger, but also at the center of each finger and along the contour edge of the entire palm surface. The body 61 and the lugs 62 are integrally made of the same stab-resistant material. In other embodiments, the body and the lugs can be made of different materials. In this embodiment, the inner layer 5 and the outer layer 7 are the same size, and the size of the body 61 is smaller than the size of the inner layer 5 and the outer layer 7. The lugs 62 are fixed together with the inner layer 5 and the outer layer 7, and there is no direct connection between the body 61 and the inner layer 5 and the outer layer 7.

[0047] In this embodiment, the inner layer 5, the puncture-resistant layer 6, and the outer layer 7 are connected by sewing, specifically using a computerized pattern sewing machine. The presser foot of the computerized pattern sewing machine is a hollow circle with a diameter of 2.5–3 mm, and the sewing needle is located at the center of the circle. The distance between the edge of each layer and the seam is 2–2.5 mm; when the distance between the edge of each layer and the seam is 3–3.5 mm, it can be ensured that the stitching is not exposed after the piece is turned over; if the distance between the edge of each layer and the seam exceeds 3.5 mm, because there is too much material excess after turning over, it will cause the material to be rough and uncomfortable to hold.

[0048] A fingertip extension surface 9 is added between the back of the hand 1 and the finger portion 3 of the palm side 2, as shown in Figure 3. The fingertip extension surface 9 adopts the aforementioned stab-resistant fabric structure. The front and rear edges of the fingertip extension surface 9 are sewn together with the edges of the finger portion 3 of the back of the hand 1 and the palm side 2, respectively. In Figure 3, the middle position of the fingertip extension surface 9 corresponds to the fingertip, and the two sides correspond to the sides of the finger. One end of the fingertip extension surface 9 extends from the inside of the index finger to the inside of the little finger and to the other end. The fingertip extension surface 9 can provide more space for finger movement. As shown in Figure 5, since the stab-resistant layer 6 is connected to the inner layer 5 and the outer layer 7 through the lug 62, not only can the body 61 of the stab-resistant layer 6 of the fingertip extension surface 9 be spliced ​​with the body 61 of the stab-resistant layer 6 of the back of the hand 1 and the palm side 2, so that the two stab-resistant layers do not overlap, reducing the thickness after splicing and improving comfort, but the fingertip extension surface 9 can also cover the fingertip, reducing the risk of damage to the protective performance.

[0049] The wrist of the back of the hand 1 and the palm of the hand 2 uses a wrist extension surface 10. The wrist extension surface 10 adopts the above-mentioned anti-puncture fabric structure. The front edge of the wrist extension surface 10 is sewn together with the rear edge of the palm of the back of the hand 1 and the palm of the hand 2, which can improve the flexibility of wrist joint movement while providing good anti-puncture effect.

[0050] In the stab-proof glove of the present invention, the edges of two stab-proof fabric structures are sewn together (such as the palm part of the back of the hand and the palm side of the hand being sewn together, the finger part and the fingertip extension surface being sewn together, and the wrist extension surface and the palm part being sewn together), and the lugs located at the sewn edges of the two stab-proof fabric structures are staggered, that is, the lugs of the stab-proof layers of the two stab-proof fabric structures are not sewn together correspondingly.

[0051] The "operational dexterity" (also referred to as "dexterity," "flexibility," or "agility") of the stab-resistant gloves of this invention is tested according to Section 6.2 of European Standard EN420:2003, and the level of dexterity is assessed according to Section 5.2 of EN420:2003. First, five solid stainless steel nails, each 40mm in length and with diameters of 5mm, 6.5mm, 8mm, 9.5mm, and 11mm respectively, are placed flat on a table. A trained operator, wearing the test glove, must smoothly and effortlessly pick up three stainless steel nails consecutively with their gloved index finger and thumb within 30 seconds, without any other assistance. The smaller the diameter of the nail that can be picked up, the higher the dexterity of the glove; conversely, the larger the diameter, the lower the dexterity. The test results are shown in the table below:

[0052] Table 1: Minimum diameter of stainless steel nails that can be picked up from different samples and corresponding dexterity level determination

[0053] Test instructions:

[0054] Glove A is a 360-degree all-around stab-proof glove. Its entire palm and back of the hand are constructed by stitching the inner layer, stab-proof layer and outer layer along the edges. The gloves are made by stitching the palm and back of the hand materials together and then turning them inside out.

[0055] Glove B is a needle-resistant glove from Mechanix Wear. Only the entire palm surface uses an inner layer, a puncture-resistant layer, and an outer layer that are stitched together along the edges, or glued together in pairs. The back of the hand does not use puncture-resistant material.

[0056] Glove C is a HexArmor needle-resistant glove. Its entire palm surface is made by stitching and gluing together an inner layer, a puncture-resistant layer, and an outer layer along the edge, while the back of the hand does not use puncture-resistant material.

[0057] Glove D is a HexArmor PointGuard 6044 puncture-resistant glove. The entire palm is made by stitching the inner layer, puncture-resistant layer and outer layer along the edge. The back of the hand is not made of puncture-resistant material.

[0058] Glove E is a 360-degree all-around stab-proof glove made with the "lug" structure of the present invention. The palm and back of the hand are made by stitching an inner layer, a stab-proof layer and an outer layer together. The stitching method of the stab-proof layer and the inner and outer layers adopts the lug structure disclosed in this application.

[0059] The test results above show that the gloves sewn with the lug structure of the present invention can ensure the flexibility of the gloves very well. At the same time, the puncture-proof layer will not slip or lose its position during use because of the lug positioning, and the protection is also more guaranteed.

[0060] The distribution of lugs on gloves is not affected by glove size. Considering that glove size greatly affects finger length (for example, each finger of an XL glove is significantly longer than that of an XS glove), we will now use the L size (the most common size) in Chinese sizing as an example to introduce the distribution density of lugs. The distribution density of lugs in other sizes of gloves can be adjusted slightly according to the actual situation. In size L gloves, for the middle and ring fingers, the lugs are distributed at a density of 3-5 on each side. For the index finger, the lugs on the side between the index and middle fingers are distributed at a density of 3-5, while the density on the other side can be slightly higher, reaching 3-8. The lugs on the side between the little and ring fingers are distributed at a density of 2-3, while the other side, connecting to the entire contour of the palm, can have 4-8 lugs. The outer side of the thumb, connecting to the outer contour of the palm, can have 3-6 lugs. Each fingertip only needs one lug. The side of the thumb connecting to the web of the thumb has 2-3 lugs. The bottom contour of the palm has 1-2 lugs for slight fixation. The distribution of lugs is exactly the same for the left and right palms. For very small gloves, such as size XS, 1-2 lugs can be reduced as needed to avoid overcrowding and reduced glove flexibility. In addition, relevant technicians can adjust the density of the lugs according to the actual product. For example, when making a pair of stab-proof gloves with a 5-layer stab-proof material, the distribution density of the lugs in each layer of stab-proof material can be appropriately reduced, and the lugs in each layer can be staggered slightly when sewing. This avoids the situation where each layer is too densely packed with lugs, causing the 5 layers to be sewn together in the same way as the traditional "sewing around the edge", which would reduce the flexibility of the product.

[0061] When two identical stab-resistant fabric structures are joined and sewn together, the two stab-resistant fabric structures are connected in the connection area by sewing the inner layer, outer layer and lug together. In the connection area, the body edge of the stab-resistant layer is not connected to the inner and outer layers. Outside the connection area, all the body edges of the stab-resistant layer are sewn together to the inner and outer layers, or part of the body edge is sewn together to the inner and outer layers, or the body edge is not sewn to the inner and outer layers.

[0062] In other embodiments, the puncture-resistant layer can be two or more layers. When stacked, the lugs of each puncture-resistant layer can overlap or be staggered. For all layers, the lugs of each layer can be staggered, staggered by one layer, staggered by two layers, or all overlapping. There are various sewing methods that can be selected according to the sewing worker's habits.

[0063] In other embodiments, at least one first functional layer is provided between the stab-resistant layer and the outer layer. The first functional layer may be a heat-insulating or radiation-resistant functional layer. The edge of the first functional layer is fixed together with the connection parts of the outer and inner layers (and simultaneously connected to the lugs of the stab-resistant layer). When the elasticity of the first functional layer is limited, the first functional layer may adopt a lug structure. The first functional layer includes a body and a plurality of lugs provided on the edge of the body. The lugs of the first functional layer are fixed together with the connection parts of the inner and outer layers. The lugs of the first functional layer and the lugs of the stab-resistant layer overlap or are staggered, and there is no connection between the body of the first functional layer and the lugs of the inner, outer, and stab-resistant layers.

[0064] In other embodiments, at least one second functional layer is provided between the puncture-resistant layer and the inner layer. This functional layer is typically a special material whose function is affected when punctured or cut. For example, a wearable, flexible, pulse-sensing functional fabric layer. This fabric, if punctured or cut, may be unable to accurately sense the pulse and function properly, therefore it must be placed below the puncture-resistant layer. If the function is not significantly and measurably affected by puncture or cut, then the functional layer can be placed between the outer layer and the puncture-resistant layer. The edge of the second functional layer is fixed together with the connection point of the outer layer and the edge of the first functional layer (or the lug of the first functional layer) (and simultaneously connected to the lug of the puncture-resistant layer). When the elasticity of the second functional layer is limited, the second functional layer may adopt a lug structure. The second functional layer includes a body and several lugs provided on the edge of the body. The lugs of the second functional layer are fixed together with the connecting parts of the inner layer, the outer layer, and the edge of the first functional layer. The lugs of the second functional layer overlap or are offset from the lugs of the anti-stab layer, and there is no connection between the body of the second functional layer and the lugs of the inner layer, the outer layer, the anti-stab layer, and the edge of the first functional layer; or the lugs of the second functional layer are fixed together with the connecting parts of the inner layer and the outer layer, the lugs of the second functional layer overlap or are offset from the lugs of the first functional layer and the anti-stab layer, and there is no connection between the body of the second functional layer and the lugs of the inner layer, the outer layer, the anti-stab layer, and the lugs of the first functional layer.

[0065] In other embodiments, the length of the lug is 4-5 mm and the width is 5-10 mm. We define the lug as follows: with the finger contour as the reference plane, the side protruding horizontally perpendicular to the finger contour is the length of the lug, and the side parallel to the finger plane is called the width of the lug. According to this definition, the length of the lug is 4-5 mm and the width is 5-10 mm for the following reasons: 1) The lug and the inner and outer layers are sewn by hand. Considering the processing precision during sewing, the length of the lug cannot be too small, otherwise there may be gaps in the sewing. However, the length of the lug cannot be too large, otherwise the protective coverage area will be lost. 2) The width of the lug cannot be too small, otherwise, due to the short stitch length, it is easy to cause "stitch breakage", that is, the stitch is too short to withstand the tension during use. The width cannot be too large either, otherwise the feel will be close to the hard and stiff feeling of traditional "sewing around the edge".

[0066] The development process of this application's technical solution is briefly described as follows: Initially, the applicant used a traditional sewing method, which involved sewing the inner layer, puncture-resistant layer, and outer layer together along the edges. However, because the puncture-resistant layer has virtually no elasticity, after all three layers were sewn together along the edges, the hand could not bend and clench its fist when wearing the glove, resulting in a loss of flexibility. Therefore, the traditional sewing process was ruled out. Secondly, the applicant wanted to produce a 360-degree all-around puncture- and cut-resistant glove, meaning that the puncture resistance not only covered the entire palm but also the entire back of the hand. Therefore, in many cases, the material structure of the back of the hand and the palm is a "three-layer" structure of the outer layer, the puncture-resistant layer, and the inner layer. When sewing the palm and back of the hand materials together to make a glove, if the traditional "sewing together along the edges" processing method is followed, the total number of sewn layers would be 6, which would make the seams very thick, greatly reducing the comfort of wearing the glove (the seams would be very scratchy and uncomfortable on the hand). If other functional layers are used between the outer and puncture-resistant layers, or between the puncture-resistant and inner layers, then when the palm and back of the hand are sewn together, following the traditional "sewing around the edge" method, the number of layers will exceed six, inevitably causing significant discomfort during subsequent use of the glove. Furthermore, since the material used is puncture-resistant, processing the puncture-resistant layer with the outer and inner layers by sewing around the edge results in the needle being unable to penetrate the puncture-resistant layer in some areas, or causing significant needle wear, greatly hindering mass production of the glove. The applicant then sewn the outer and inner layers together, leaving the middle puncture-resistant layer unsewn, merely sandwiched between the outer and inner layers. However, it was found that while this method allows the hand to clench, the puncture-resistant layer, being sandwiched without fixation, will slip and shift during use, resulting in a loss of protective performance. In addition, the applicant found that the smaller the middle puncture-resistant layer, the greater the overall flexibility, but the larger the area of ​​lost protection, and the more dangerous it becomes. Therefore, traditional sewing techniques cannot meet the requirements of both "high flexibility" and "large protective area coverage". To solve this technical problem, the applicant first started with the goal of local connection and fixation between the puncture-resistant layer and the inner and outer layers. In order to achieve local connection and fixation of the puncture-resistant layer, various connection forms were designed during the research and development period. After comparing and verifying various schemes, it was finally determined that the puncture-resistant layer adopts a lug structure for connection and fixation, which can well meet the requirements of "high flexibility" and "large protective area coverage". Moreover, when the palm material and the back of the hand material are spliced ​​and sewn into gloves, the actual total number of layers sewn together is 4, which makes the thickness of the seam smaller and will not affect the comfort of wearing the gloves. In addition, sewing is easy, can ensure sewing quality, reduce needle wear, and realize the mass production of gloves.
