Description

Technical Field

[0001] The invention relates to a stab-proof fabric structure having both comfort and stab-proof performance, and also relates to stab-proof gloves made of the stab-proof fabric structure. Background Art

[0002] For protective equipment such as stab-proof gloves and stab-proof clothing, the function of preventing punctures from sharp objects is very important. The stab-proof materials used in existing protective equipment often have very limited elasticity, because too high elasticity will cause the pores of the material to deform and expand, allowing sharp objects such as needles to pass through easily. However, applying stab-proof materials with very limited elasticity to human joints will hinder joint movement, thereby reducing the flexibility of joint movement and greatly reducing human comfort.

[0003] The stab-proof fabric structure used in existing protective equipment is that the inner layer, the stab-proof layer and the outer layer are sewn together along the edges. When the joints move, the stab-proof layer will inevitably be pulled, and the stab-proof layer will hinder the pulling due to its limited elasticity, resulting in obstructed movement of the joints.

[0004] In order to solve the above problems, the existing method is to sew the outer layer and the inner layer together and reduce the size of the middle stab-proof layer and sandwich it between the outer layer and the inner layer. Since there is no fixation between the stab-proof layer and the outer layer and the inner layer, the stab-proof layer can slide between the two layers, so it will not hinder the movement of human joints and can improve human comfort. However, this method has the following defects:

[0005] ⑴The puncture-proof layer may slide during use, bringing risks to the protective performance.

[0006] (2) The stab-proof layer may curl, which may bring risks to the protective performance and reduce human comfort. Summary of the invention

[0007] The first object of the present invention is to provide a stab-proof fabric structure which has a simple structure, low cost, good stab-proof performance and can improve the flexibility of human joint movements, thereby improving human comfort and having both comfort and stab-proof performance.

[0008] The first object of the present invention is achieved through the following technical measures: a stab-proof fabric structure with both comfort and stab-proof performance, comprising an inner layer, an outer layer and a stab-proof layer therebetween, wherein the edges of the inner layer and the outer layer are connected together, and characterized in that the stab-proof layer comprises a main body and a plurality of lugs arranged on at least a part of the edge of the main body, the area being called a connecting area, the lugs being fixed together with the connecting parts of the inner layer and the outer layer, and there is no connection between the edge of the main body in the connecting area and the inner layer and the outer layer.

[0009] The stab-proof layer of the present invention is connected to the inner layer and the outer layer through the lugs, so that the stab-proof layer is partially fixed. When in use, the stab-proof layer can be in a predetermined position without sliding, and the stab-proof layer is prevented from rolling inward, so that the reliability of needle puncture prevention can be ensured. At the same time, when the present invention is applied to the joints of the human body, it can be stretched by the lugs without hindering the joint movement when the human joint moves. Therefore, any stab-proof material with no elasticity or very limited elasticity can be used in positions where the flexibility of human body movements is required, such as the back of the hand, the knuckles of the gloves and the elbow joints of the stab-proof clothing, so as to meet the flexibility requirements of joint bending, etc. Another example is the production of 360-degree all-round cut and stab-resistant gloves, that is, the entire palm and the back of the hand need to use inelastic or very limited elastic stab-resistant materials; in addition, when the present invention is applied to protective equipment, two pieces of stab-resistant fabrics are butt-jointed and sewn, because the stab-resistant layer of each piece of stab-resistant fabric is sewn together with the inner layer and the outer layer through the lugs, so that the bodies of the stab-resistant layers of the two pieces of stab-resistant fabrics are spliced ​​together, compared with the existing stab-resistant fabrics in which the inner layer, the stab-resistant layer and the outer layer are sewn together along the edges of the three, the thickness of the present invention after the two pieces of stab-resistant fabrics are spliced ​​together is reduced, thereby improving comfort.

[0010] When the present invention connects and sews two identical stab-proof fabric structures, the two stab-proof fabric structures are connected in a connection area in a manner that the inner layer, the outer layer and the lugs are sewn together, and in the connection area, the edge of the body of the stab-proof layer is not connected to the inner layer and the outer layer, while outside the connection area, all the edges of the body of the stab-proof layer are sewn together with the inner layer and the outer layer, or part of the edges of the body are sewn together with the inner layer and the outer layer, or the edges of the body are not sewn together with the inner layer and the outer layer.

[0011] The stab-proof layer of the present invention comprises two or more layers, and the lugs of each stab-proof layer overlap or stagger with each other.

[0012] The present invention provides at least one first functional layer between the stab-proof layer and the outer layer, and the edge of the first functional layer is fixed to the connecting parts of the outer layer and the inner layer and the connecting parts of the outer layer, the inner layer and the stab-proof layer lugs.

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

[0014] The present invention provides at least one second functional layer between the stab-proof layer and the inner layer, the second functional layer includes a body and a plurality of 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 with or are staggered with the lugs of the stab-proof layer, and there is no connection between the body of the second functional layer and the inner layer, the outer layer, the lugs of the stab-proof layer and the edge of the first functional layer.

[0015] The present invention provides at least one first functional layer between the stab-proof layer and the outer layer, the first functional layer comprising a main body and a plurality of lugs provided on the edge of the main body, the lugs of the first functional layer being fixed together with the connecting parts of the inner layer and the outer layer, the lugs of the first functional layer being overlapped with or staggered with the lugs of the stab-proof layer, and there being no connection between the main body of the first functional layer and the lugs of the inner layer, the outer layer and the stab-proof layer.

[0016] In the present invention, at least one second functional layer is arranged between the stab-proof layer and the inner layer, and the edge of the second functional layer is fixed to the connection part between the outer layer and the inner layer.

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

[0018] The layers of the invention are connected by sewing, specifically by sewing with a computer pattern machine, the presser foot of the computer pattern machine is a hollow circle with a diameter of 2.5-3mm, and the sewing needle is at the center of the circle. The distance between the edge of each layer and the seam line of the invention is 2-2.5mm; when the distance between the edge of each layer and the seam line of the invention is 3-3.5mm, it can be ensured that the press line is not exposed after the stitching is turned over; if it exceeds 3.5mm, because there is too much material surplus after turning over, the material will scratch and hit the hand, and the comfort is poor.

[0019] The lug of the present invention has a length of 4 to 5 mm and a width of 5 to 10 mm.

[0020] The body and the lug of the present invention are made of the same stab-proof material in one piece.

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

[0022] The second object of the present invention is to provide a stab-proof glove made using the stab-proof fabric structure.

[0023] The second object of the present invention is achieved by the following technical measures: a stab-proof glove made of the above-mentioned stab-proof fabric structure, comprising a back of the hand and a palm surface, the front part of the back of the hand and the palm surface is a finger part, the rear part is a palm part, and the rear end of the palm part is a wrist part, characterized in that the back of the hand and the palm surface both adopt the stab-proof fabric structure, and the finger parts and palm parts of the back of the hand and the palm surface are respectively aligned and sewn together at the edge position to obtain the stab-proof glove.

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

[0025] The present invention is provided with a fingertip extension surface, which can provide a larger activity space for the fingers, and because the stab-proof layer is connected to the inner layer and the outer layer through the lug, not only can the stab-proof layer body of the fingertip extension surface 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 of the body after splicing and turning over, thereby improving comfort, but also the fingertip extension surface can cover the fingertips, thereby reducing the risk of protective performance.

[0026] The wrist of the back and palm of the present invention uses a wrist extension surface, the wrist extension surface adopts the stab-proof fabric structure, and the front edge of the wrist extension surface is sewn together with the rear end edge of the palm of the back and palm.

[0027] The edges of the two stab-proof fabric structures of the present invention are sewn together, and the lugs located at the sewn edges of the two stab-proof fabric structures are staggered.

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

[0029] (1) The stab-proof layer of the present invention is connected to the inner layer and the outer layer through the lugs, so that the stab-proof layer is partially fixed. When in use, the stab-proof layer can be in a predetermined position without sliding, and the stab-proof layer is prevented from rolling inward, so that the reliability of needle puncture protection can be ensured. At the same time, the present invention is applied to the joints of the human body. When the joints of the human body move, the stab-proof layer can be stretched by the lugs without hindering the movement of the joints. Therefore, any stab-proof material with no elasticity or very limited elasticity can be used in positions where the flexibility of human body movements is required, such as the back of the hand, the knuckles of the gloves and the elbow joints of the stab-proof clothing, so as to meet the flexibility requirements of joint bending.

[0030] (2) When the present invention is applied to protective equipment, two pieces of stab-proof fabrics are butt-jointed and sewn together. Since the stab-proof layer of each piece of stab-proof fabric is sewn together with the inner layer and the outer layer through the lugs, the bodies of the stab-proof layers of the two pieces of stab-proof fabrics are spliced ​​together. Compared with the existing stab-proof fabrics in which the inner layer, the stab-proof layer and the outer layer are sewn together along the edges, the thickness of the present invention after the two pieces of stab-proof fabric are spliced ​​together is reduced, thereby improving comfort.

[0031] (3) The stab-proof gloves of the present invention are provided with fingertip extension surfaces, which can provide a larger activity space for fingers, and because the stab-proof layer is connected to the inner layer and the outer layer through the lugs, not only can the stab-proof layer body of the fingertip extension surface 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 of the body after splicing and turning over, improving comfort, but also the fingertip extension surface can cover the fingertips, reducing the risk of protective performance.

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

[0033] (5) The present invention can be partially or fully applied to any protective equipment, has strong practicality, and is suitable for wide promotion and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The present invention is further illustrated below through the description of specific implementation methods, 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 deviate from the basic idea of ​​the present invention, they are all within the protection scope of the present invention.

[0045] like Figures 1 to 8 As shown, a stab-proof glove of the present invention comprises a back side of the hand 1 and a palm side 2, the front part of the back side of the hand 1 and the palm side 2 is a finger part 3, the rear part is a palm part 4, the rear end of the palm part 4 is a wrist part, the back side of the hand 1 and the palm side 2 are both made of a stab-proof fabric structure with both comfort and stab-proof performance, the finger part 3 and the palm part 4 of the back side of the hand 1 and the palm side 2 are respectively aligned and sewn together at the edge position to obtain the stab-proof glove.

[0046] The stab-proof fabric structure with both comfort and stab-proof performance used in the stab-proof gloves of the present invention comprises an inner layer 5, an outer layer 7 and an stab-proof layer 6 therebetween. The edges of the inner layer 5 and the outer layer 7 are connected together. The stab-proof layer 6 mainly provides cut and stab-proof functions (the stab-proof fabric also has cut-proof functions). It can adopt a stab-proof material with a Young's modulus of 5 to 1000 MPa, such as plain fabric, double-sided cotton and wool knitted fabric, or cut and stab-proof fabric with steel wire or tungsten wire wrapped inside. In this embodiment, the stab-proof layer 6 is a single layer; the outer layer 7 mainly plays the role of wear resistance, anti-slip, flame retardant, fireproof and protection of the stab-proof layer; the function of the inner layer 5 is mainly to absorb sweat close to the skin. The stab-proof layer 6 is composed of a body 61 and a plurality of lugs 62 arranged on the edge of the body 61. In this embodiment, the length of the lugs 62 is 4 mm and the width is 5 mm. The distance between adjacent lugs 62 can be determined according to actual conditions. In the stab-proof gloves of this embodiment, the lugs are distributed on the entire palm surface. In the top view of the palm surface, the lug structure is not only distributed on both sides of each finger, but also distributed in the center of each finger and along the contour edge of the entire palm surface. The body 61 and the lugs 62 are made of the same stab-proof material. In other embodiments, the body and the lugs can also be made of different materials. The inner layer 5 and the outer layer 7 of this embodiment are the same size. The size of the body 61 is smaller than that of the inner layer 5 and the outer layer 7. The lugs 62 are fixed to the connection parts of 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 stab-proof layer 6 and the outer layer 7 are connected by sewing, specifically by using a computer pattern machine. The presser foot of the computer pattern machine is a hollow circle with a diameter of 2.5-3 mm, and the sewing needle is at the center of the circle. The distance between the edge of each layer and the stitching line is 2-2.5 mm; when the distance between the edge of each layer and the stitching line is 3-3.5 mm, it can be ensured that the stitching line is not exposed after turning over the body; if the distance between the edge of each layer and the stitching line exceeds 3.5 mm, because there is too much material surplus after turning over, it will cause the material to scratch and hit the hand, and the comfort is poor.

[0048] A fingertip extension surface 9 is provided between the finger portion 3 of the back of the hand 1 and the palm surface 2. Figure 3 As shown, the fingertip extension surface 9 adopts the above-mentioned stab-proof fabric structure, and the front and rear side 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 surface 2, respectively. Figure 3 The middle position of the middle finger tip extension surface 9 corresponds to the finger tip, and the two side positions correspond to the two sides of the finger. One end of the finger tip extension surface 9 extends from the inner side of the index finger to the inner side of the little finger and to the other end. The finger tip extension surface 9 can provide a larger activity space for the fingers, such as Figure 5 As shown, since the stab-proof layer 6 is connected to the inner layer 5 and the outer layer 7 through the lugs 62, not only can the stab-proof layer 6 body 61 of the fingertip extension surface 9 be spliced ​​with the stab-proof layer 6 body 61 of the back of the hand 1 and the palm surface 2, so that the two stab-proof layers do not overlap, reducing the thickness of the body after splicing and turning over to improve comfort, but also the fingertip extension surface 9 can cover the fingertips, reducing the risk of protection performance.

[0049] The wrist extension surface 10 is used on the wrist of the back side of the hand 1 and the palm side 2. The wrist extension surface 10 adopts the above-mentioned stab-proof fabric structure. The front edge of the wrist extension surface 10 is sewn together with the rear end edge of the palm of the back side of the hand 1 and the palm side 2, which can improve the flexibility of the wrist joint movement while playing a good stab-proof role.

[0050] In the stab-proof gloves of the present invention, the edges of the two stab-proof fabric structures are sewn together (for example, the palm of the back of the hand and the palm surface are sewn together, the finger portion and the fingertip extension surface are sewn together, and the wrist extension surface and the palm portion are 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" and "flexibility") of the stab-proof gloves of the present invention is tested according to Section 6.2 of the European standard EN420:2003, and the dexterity level is evaluated according to Section 5.2 of EN420:2003. First, five solid stainless steel nails with a length of 40 mm and diameters of 5 mm, 6.5 mm, 8 mm, 9.5 mm and 11 mm are placed flat on the table. A trained operator puts on the gloves to be tested and, without any other assistance, picks up the stainless steel nails three times in a row with the index finger and thumb after wearing the gloves smoothly, silkily and without mistakes within 30 seconds. The smaller the diameter of the stainless steel nail that can be picked up, the higher the dexterity of the glove, and vice versa. The test results are shown in the following table:

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

[0053]

[0054] Test description:

[0055] Glove A is a 360-degree all-round stab-proof glove. The entire palm surface and the entire back of the hand are structured by sewing the inner layer, the stab-proof layer and the outer layer along the edges, and then the palm surface and the back of the hand are sewn together and turned over to make the glove.

[0056] Glove B is a puncture-proof glove from Mechanix Wear. Only the entire palm surface has the inner layer, puncture-proof layer and outer layer fully sewn along the edges, or glued together in pairs. No puncture-proof material is used on the back of the hand.

[0057] Glove C is a HexArmor anti-puncture glove. The entire palm surface is made of an inner layer, an anti-puncture layer and an outer layer that are sewn and glued along the edges, while the back of the hand is not made of anti-puncture material.

[0058] Glove D is a PointGuard 6044 model of HexArmor's needle-puncture-resistant gloves. The entire palm surface is made of an inner layer, an anti-puncture layer and an outer layer sewn together along the edges, and no anti-puncture material is used on the back of the hand.

[0059] Glove E is a 360-degree all-round stab-proof glove made of the "bulge ear" structure of the present invention. The palm and the back of the hand are made by sewing the inner layer, the stab-proof layer and the outer layer, wherein the sewing method of the stab-proof layer and the inner layer and the outer layer adopts the lug ear structure disclosed in the present application.

[0060] The above test results show that the gloves sewn with the lug structure of the present invention can well ensure the flexibility of the gloves. At the same time, the anti-stab layer will not slide out of place during use because of the lug positioning, and the protective performance is also better guaranteed.

[0061] The distribution position of the lugs on the gloves is not affected by the size of the gloves. Considering that the size of the gloves will greatly affect the length of the fingers of the gloves (for example, the length of each finger of the XL size gloves is significantly longer than that of the XS size), we will now take the L size (the most common size) in Chinese sizes as an example to introduce the distribution density of the lugs. The distribution density of the lugs in gloves of other sizes can be slightly adjusted according to the actual situation. In size L gloves, for the middle finger and the ring finger, the lugs are distributed on both sides of these two fingers with a density of 3-5 on each side; for the index finger, the lugs on one side of the gap between the index finger and the middle finger are distributed with a density of 3-5, while the density of the lugs on the other side of the index finger can be slightly larger, reaching 3-8; the lugs on one side of the gap between the little finger and the ring finger are distributed with a density of 2-3, and the other side connected to the entire outline of the palm side can be distributed with 4-8 lugs; the outer side of the thumb connected to the outer contour of the palm can be distributed with 3-6 lugs; only 1 lug is distributed on the fingertips of each finger; 2-3 lugs are distributed on the side of the thumb connected to the base of the thumb; 1-2 lugs are distributed at the bottom of the palm to slightly fix it; the distribution of the above lugs is exactly the same for the left and right palms. For gloves of very small size, such as size XS, 1-2 lugs can be appropriately reduced according to actual conditions to avoid the lugs being too crowded and reducing the flexibility of the gloves. 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 5 layers of stab-proof material, the distribution density of the lugs of each layer of stab-proof material can be appropriately reduced, and the lugs of each layer can be sewed slightly staggered to avoid the situation where the 5 layers are sewn together like the traditional "sewing a circle along the edge" due to excessive density of lugs on each layer, thereby reducing the flexibility of the product.

[0062] When two identical stab-proof fabric structures are connected and sewn together in the present invention, the two stab-proof fabric structures are connected in a connection area in a manner that the inner layer, the outer layer and the lugs are sewn together, and in the connection area, the edge of the body of the stab-proof layer is not connected to the inner layer and the outer layer, while outside the connection area, all the edges of the body of the stab-proof layer are sewn together with the inner layer and the outer layer, or part of the edges of the body are sewn together with the inner layer and the outer layer, or the edges of the body are not sewn together with the inner layer and the outer layer.

[0063] In other embodiments, the stab-proof layer can be more than two layers, and when stacked, the lugs of each stab-proof layer can overlap or stagger. For all layers, the lugs of each layer can be staggered, staggered every other layer, staggered every other two layers, or all overlapped together. There are many sewing methods, which can be selected according to the habits of the sewing workers.

[0064] In other embodiments, at least one first functional layer is provided between the stab-proof layer and the outer layer, and the first functional layer is a functional layer such as a heat-insulating layer or a radiation-resistant layer. The edge of the first functional layer is fixed to the connecting portion of the outer layer and the inner layer (and is connected to the lugs of the stab-proof layer at the same time); when the elasticity of the first functional layer is limited, the first functional layer may adopt a lug structure, and the first functional layer includes a body and a plurality of lugs provided on the edge of the body, and the lugs of the first functional layer are fixed to the connecting portion of the inner layer and the outer layer, and the lugs of the first functional layer overlap or stagger with the lugs of the stab-proof layer, and 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-proof layer.

[0065] In other embodiments, at least one second functional layer is provided between the stab-proof layer and the inner layer. This functional layer is usually a special material whose function is affected after being punctured or cut. For example, a wearable, flexible, functional fabric layer that can sense the human pulse. After being punctured or cut, this fabric may not be able to accurately sense the human pulse and cannot function normally to achieve its intended function, so it must be placed below the stab-proof layer. If the function of the functional layer is not significantly and measurably affected after being punctured or cut, then the functional layer can be placed between the outer layer and the stab-proof layer. The edge of the second functional layer is fixed to the connection between the edge of the first functional layer of the outer layer and the inner layer (or the lug of the first functional layer) (and the lug of the stab-proof layer is connected at the same time). When the elasticity of the second functional layer is limited, the second functional layer may adopt a lug structure, wherein the second functional layer includes a body and a plurality of lugs arranged 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 with or staggered with the lugs of the stab-proof layer, and there is no connection between the body of the second functional layer and the inner layer, the outer layer, the lugs of the stab-proof 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 with or staggered with the lugs of the first functional layer and the lugs of the stab-proof layer, and there is no connection between the body of the second functional layer and the inner layer, the outer layer, the lugs of the stab-proof layer, and the lugs of the first functional layer.

[0066] In other embodiments, the length of the lug is 4-5 mm, and the width is 5-10 mm. We stipulate that: taking the finger contour as the reference plane, the side that is perpendicular to the finger contour and protruding horizontally is the length of the lug, and the side that is parallel to the finger plane is called the width of the lug. According to this definition, the length of the lug ranges from 4 to 5 mm, and the width ranges from 5 to 10 mm. The reasons are as follows: 1) The lug and the inner layer and the outer layer are manually sewn. Considering the processing accuracy during sewing, the length of the lug cannot be too small, otherwise there may be leakage during sewing, but 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 it is easy to cause "broken line" after sewing because the length of the suture is too small, that is, the suture is too short to withstand the tension during use, and the width cannot be too large, otherwise the hand feel will be close to the traditional "sewing a circle along the edge" hard and stiff feeling.

[0067] The research and development process of the technical solution of this application is briefly described as follows: Initially, the applicant adopted the traditional sewing method, that is, the inner layer, the stab-proof layer and the outer layer, a total of three layers, were sewn together along the edges. However, because the stab-proof layer has basically no elasticity, after all three layers were sewn together along the edges, after putting on the gloves, the hands could not bend and clench into fists, and lost flexibility. Therefore, the traditional sewing process was ruled out; secondly, the applicant wanted to prepare 360-degree all-round stab-proof and cut-proof gloves, that is, the stab-proof function not only covers the entire palm surface, but also the entire back of the hand. Therefore, in many cases, the material structure of the back of the hand and the palm surface is a "three-layer" structure of the outer layer, the stab-proof layer and the inner layer. When the palm surface material and the back of the hand material are spliced ​​and sewn into gloves, if the traditional "sewing together along the edges" processing method is used, then the total number of layers sewn together is 6 layers, which will make the seams very thick, greatly reducing the comfort of the gloves when worn (the seams will be very scratchy and hit the hands). If other functional layers are used between the outer layer and the stab-proof layer or between the stab-proof layer and the inner layer, when the palm and the back of the hand are sewn together, according to the traditional method of "sewing a circle along the edge", the number of layers sewn together will exceed 6 layers, which will inevitably bring great discomfort to the subsequent use of the gloves. In addition, the material we use is stab-proof material itself. When the stab-proof layer, the outer layer and the inner layer are processed by sewing a circle along the edge, the sewing needle will be very difficult to penetrate the stab-proof layer, causing some positions to be unable to be sewn, or the sewing needle loss is extremely large, which brings great trouble to the mass production of gloves. Then, the applicant sewed the outer layer and the inner layer together, and the middle stab-proof layer was processed by not sewing and only being sandwiched by the outer layer and the inner layer. However, it was found that although this method can make the hand clenched into a fist, the stab-proof layer is only sandwiched in the middle and not fixed, and it will slide and dislocate during use, resulting in a lack of protective performance. In addition, the applicant found that the smaller the middle stab-proof layer is, the higher the overall flexibility is, but the larger the area of ​​protection loss is, the more dangerous it is. Therefore, the traditional sewing process cannot meet the requirements of both "high flexibility" and "large protection area coverage". In order to solve this technical problem, the applicant first starts from the goal of locally connecting and fixing the anti-stab layer and the inner layer and outer layer. In order to achieve local connection and fixation of the anti-stab layer, various connection forms are designed during the research and development period. After comparison and experimental verification of multiple schemes, it is finally determined that the anti-stab layer is connected and fixed with a lug structure, which can well meet the requirements of "high flexibility" and "large protection area coverage". Moreover, when the palm surface material and the back surface material are spliced ​​and sewn into gloves, the total number of layers actually sewn together is 4 layers, so that the thickness of the seam is small, which will not affect the comfort of the gloves when worn. In addition, sewing is easy, the sewing quality can be guaranteed, the needle loss can be reduced, and the mass production of gloves can be realized.
