Such industrial operations are usually required not to wear gloves to reduce the risk of gloves being caught and causing hand injuries. However, if gloves are not worn, basic mechanical protection cannot be performed. Taking the metal cutting scene as an example, a large amount of sharp and sharp metal chips will fly out during the cutting process, causing cuts, punctures and other hand injuries.

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.
[0030] In the description of the present utility model, it should be noted that the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, it should be noted that the orientation or position relationship indicated by the terms "inside" and "outside" is based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, or the orientation or position relationship commonly understood by those skilled in the art. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the equipment or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. The term "and / or" when used to list two or more items means that any one of the listed items can be adopted by itself, or any combination of two or more of the listed items can be adopted.
[0031] The utility model provides an easy-to-wear and take-off glove with improved safety performance. Figures 1a-1f and Figure 5 As shown, the glove comprises a finger portion 1 and a palm portion 2, the glove has a tearable area 3 and a safety area 4, the tearable area 3 is arranged around at least one finger portion 1 and / or around the palm portion 2; the tearing force of the tearable area 3 is less than the tearing force of the safety area 4; and a safety reinforcement structure is provided between the tearable area 3 and the safety area 4.
[0032] The tearing force of the tearable area 3 of the glove is less than that of the safety area 4, so that when the glove is entangled in a machine, it can be easily torn and pulled apart from the tearable area 3 pre-set at the finger or palm, and the user can quickly pull the hand away to avoid the hand being entangled in the machine and causing serious dangerous accidents, thereby achieving safety protection. In particular, the safety reinforcement structure set between the tearable area 3 and the safety area 4 makes it easier to concentrate the tension in the tearable area 3, and the tension is more uniform in the tearable area 3, which is more conducive to tearing and pulling apart, thereby improving the safety performance (easy tearing performance) of the glove.
[0033] The tearable area 3 and the safety area 4 can be woven with the same yarn or different yarns, and the density of the tearable area 3 is smaller than that of the safety area 4. Preferably, the breaking force of the tearable area 3 is 20%-50% of the breaking force of the safety area 4, so that the tearable area 3 is softer than the safety area 4 and easier to tear and break. In order to make the tearable area 3 easy to tear and break, the breaking force of the tearable area 3 is preferably not more than 100N. It can be understood that the density of the tearable area 3 is less than the density of the safety area 4, including that the yarn density of the tearable area 3 is less than the yarn density of the safety area 4, and the tearable area 3 and the safety area 4 are woven with low-density yarn and high-density yarn respectively; also includes that the fabric density of the tearable area 3 is less than the fabric density of the safety area 4, the tearable area 3 is loosely woven, and the safety area 4 is dense and firm; also includes that the thickness of the tearable area 3 is less than the thickness of the safety area 4, and the woven yarn, the tightness of the woven and the woven thickness can be set as needed. In order to maintain wearing comfort, the inner surface of the glove can be kept flat during weaving.
[0034] Example 1
[0035] In this embodiment, if Figures 1a-1f As shown, the safety reinforcement structure is a sawtooth connection structure 41. Corresponding to the tearable area 3, the sawtooth connection structure 41 is arranged around the fingers or palms, which can increase the density of the junction of the tearable area 3, making it easier to concentrate the tension in the tearable area 3, which is more conducive to tearing. Figure 2 and Figure 3 As shown, the serrated connection structure 41 includes V-shaped serrations and wavy serrations, and the wavy serrations include trapezoidal serrations or arcuate serrations, etc., which are serrated structures capable of concentrating the pulling force on the tearable area 3 .
[0036] Specifically, the safety area 4 has a zigzag junction border, and the knitting loops of the tearable area 3 fill the space toward the zigzag junction border of the tearable area 3. The middle part of the safety area 4 can be woven normally, and the border of the safety area 4 is woven into a long zigzag (V-shaped) or wide wavy zigzag junction border through the tuck loop 411, and the space toward the zigzag junction border of the tearable area 3 is knitted and filled with low-density yarn loops of the tearable area 3.
[0037] Preferably, the safety area 4 is formed by twisting the first yarn and the second yarn and then weaving them; the tearable area 3 is formed by weaving the second yarn; the zigzag connecting boundary is formed by twisting the first yarn and the second yarn and then weaving them through a collection loop 411, so that the tearable area 3 is smaller in density, weaker, and easier to tear and break than the safety area 4.
[0038] Specifically, the first yarn is formed by twisting a first wire and a second wire; the first wire includes a glass fiber core wire and a 60-90D first covering wire coated on the glass fiber core wire; the second wire is a 50-100D ultra-high molecular weight polyethylene wire; the twist of the first yarn formed by twisting is 500-800 twists / m; the second yarn includes a 20-40D spandex core wire and a 50-100D second covering wire coated on the spandex core wire. The first covering wire and the second covering wire can use nylon wire, polyester wire, polypropylene wire or acrylic wire as covering wires, preferably, the first covering wire and the second covering wire use the same wire. The high-density safety area 4 plays a role in anti-cutting and wear-resistant, and the anti-cutting performance can reach EN388 anti-cutting level 5. The low-density tearable area 3 plays a basic connection, which can be torn by tension in the event of an emergency clamping accident, and the hand can be quickly pulled out.
[0039] Specifically, the finger portion 1 of the glove has a thumb portion and four finger portions; the tearable area 3 is arranged at the root knuckles of each finger portion 1; and / or, the tearable area 3 is arranged at the first knuckle of the thumb; and / or, the tearable area 3 is arranged at the first knuckles of the four fingers; and / or, the tearable area 3 is arranged at the second knuckles of the four fingers; and / or, the tearable area 3 is arranged at the palm joint; and / or, the tearable area 3 is arranged at the palm portion 2 between the root of the thumb and the wrist.
[0040] The safety area 4 of the glove is harder, and the tearable area 3 is softer. When operating with the hand, the joints of the fingers and the palm joints (the part where the palm is bent when making a fist) need to move. Setting the tearable area 3 at the finger joints and palm joints is conducive to joint movement, which can improve the comfort of using the gloves and the flexibility of hand operation. Depending on the usage scenario, the tearable area 3 can be set at at least one joint of at least one finger 1, or at the palm joint, or at the palm 2 between the base of the thumb and the wrist. The setting position of the tearable area 3 at each finger joint, palm joint, and other parts of the palm can be set separately or combined with each other.
[0041] In most uses, most areas of the gloves are at risk of being caught in the equipment. In order to improve the safety protection effect, in one embodiment, Figure 1a As shown, the tearable area 3 is arranged at the thumb (each knuckle from the fingertip downward is respectively arranged as the first knuckle and the root knuckle) and the root knuckles of the four fingers (each knuckle from the fingertip downward is respectively arranged as the first knuckle, the second knuckle and the root knuckle). When the finger part of the glove is caught in the device, it can be torn and pulled apart from the root knuckle, and the user's fingers are more easily separated from the finger part 1 of the glove, so as to fully protect the hand. In another embodiment, as Figure 1b As shown, a tearable area 3 can be provided on the palm part 2 at the same time. For example, when the back of the palm part is rolled into the device during hand grasping operation, the tearable area 3 provided on the palm part 2 can be torn and pulled apart, so that the fingers can be easily pulled out of the glove. In particular, when the wrist of the glove is relatively long, the time of pulling the hand out of the wrist can be saved. In other embodiments, in order to improve the comfort of use and enhance the protective effect, such as Figure 1c-1f As shown, a tearable area 3 can also be provided at each knuckle of each finger portion 1. In this way, when metal processing involves rotation and rolling, once the front section of the glove is entangled by the machine, the glove can be quickly torn and the user's hand can be immediately pulled out, thus preventing major accidents such as mechanical crushing.
[0042] In order to improve the wear resistance and durability of the gloves, a wear-resistant layer 6 can be provided on the outer surface of the safety area 4. Preferably, a wear-resistant coating can be formed by dipping with a glue solution such as nitrile rubber, latex or polyurethane. According to needs, the safety area 4 can be dipped in glue in its entirety or in part, such as 1 / 2 dipping, 2 / 3 dipping, 3 / 4 dipping, etc. For example, the outer surface of the safety area 4 of the gloves can be dipped in a nitrile glue solution and then dried, which can further improve the wear resistance and durability of the safety area 4, and the wear resistance can reach EN388 wear resistance level 4, and the gloves can have a certain waterproof effect.
[0043] The glue for forming the wear-resistant layer 6 is mostly water-based glue. In order to prevent the water-based glue from adhering to the tearable area 3 when the glove is dipped in the glue, a hydrophobic layer 7 is provided on the outer surface of the tearable area 3. Figure 4 As shown, the area after hydrophobic pretreatment can form a mask to isolate the aqueous glue. During the process of dipping the glue, the aqueous glue will not adhere to the tearable fabric area after the hydrophobic treatment, and the tearing performance will not be affected by the adhesion of the tearable area 3 by the glue. At the same time, the hydrophobic layer is relatively thin, and its own breaking force is also smaller than the breaking force of the wear-resistant layer, so it has little effect on the breaking force of the tearable area 3. When the gloves are used, the hydrophobic layer 7 can also play a waterproof role. The hydrophobic layer 7 can be coated on the outer surface of the tearable area 3, or it can be infiltrated into the yarn of the tearable area 3 to form a hydrophobic isolation layer on the outer surface.
[0044] In order to improve the comfort of gloves, the width of the tearable area 3 is set to 3-5mm, which is conducive to the movement of finger joints and palm joints and improves the flexibility of hand operation. The tearable area 3 plays a basic connection role. The width of the tearable area 3 can be set to 3mm, 4mm, 5mm, etc. Setting a suitable tearable area 3 width can prevent the tearable area 3 from being too large, reducing the protective effect of the safety area 4, and prevent the tearable area 3 from being too small, affecting the comfort of use, and can also facilitate the coating of the hydrophobic layer 7.
[0045] Generally, the first joint of the thumb and the second joint of the fourth finger have greater mobility, such as Figure 1e and Figure 1f As shown, the width of the tearable area 3 arranged at the first knuckle of the thumb and the width of the tearable area 3 arranged at the second knuckle of the fourth finger are made greater than the width of other tearable areas 3, or multiple groups of tearable areas 3 are arranged at the first knuckle of the thumb and the second knuckle of the fourth finger, preferably, two groups are arranged, so that the area can be softer and easier to bend, thereby making it easier to reduce the tension of finger bending during work, improve the wearing comfort of the user, reduce fatigue, and improve work efficiency.
[0046] In order to improve the anti-slip effect of the gloves and improve the comfort of use, a bionic palm print design can be adopted, and an anti-slip palm print is set in the safety area 4. In this way, the anti-slip palm print can provide excellent anti-slip performance while improving wearing comfort, reducing user hand fatigue and improving work efficiency. The anti-slip palm print can be set into a variety of textures, for example, it can be set into a Y-shaped texture, a triangular texture, a circular radial texture or a staggered strip texture. The Y-shaped texture can improve the anti-slip ability in multiple directions and make the palm area have a certain stretchability; the triangular texture can improve the grip of workpieces with higher curvature; the radial area of the center of the circular radial texture is the main contact area, which can effectively enhance the anti-slip property of the contact area; the staggered strip texture can increase the anti-slip property in multiple directions.
[0047] Example 2
[0048] The other components of this embodiment are the same as those of embodiment 1, and the difference from embodiment 1 is that Figure 5 As shown, the safety reinforcement structure is a reinforcement ring 5, and the tensile force of the reinforcement ring 5 is greater than the tensile force of the safety area 4. Corresponding to the tearable area 3, the reinforcement ring 5 is arranged around the finger or palm. Compared with the safety area 4, the tensile resistance of the reinforcement ring 5 is further enhanced. The reinforcement ring 5 is more rigid and harder. The tearable area 3 is arranged between two reinforcement rings 5, and the density at the junction of the tearable area 3 is increased, so that the tension is more easily concentrated in the tearable area 3, which is more conducive to tearing and breaking. Reference Figures 1a-1f As shown, the arrangement positions of the tearable area 3 and the reinforcement ring 5 of this embodiment are the same as those of embodiment 1, and will not be repeated here.
[0049] Preferably, the safety area 4 is formed by weaving the first yarn and the second yarn after twisting or U2 weaving; the tearable area 3 is formed by weaving the second yarn; the reinforcing ring 5 can be formed by ordinary weaving after twisting the first yarn, the second yarn and the third yarn, or the inner, middle and outer layers are simultaneously weaved using the U3 process, and the density of the reinforcing ring 5, the safety area 4 and the tearable area 3 decreases in sequence, the tearable area 3 is weaker, easier to tear and break, and the weaving process is simpler. The reinforcing ring 5 can also be twisted by weaving the first yarn, the second yarn and the third yarn into a zigzag shape to further improve the tearability.
[0050] Specifically, the first yarn is formed by twisting a first wire and a second wire; the first wire includes a glass fiber core wire and a 60-90D first covering wire coated on the glass fiber core wire; the second wire is a 50-100D ultra-high molecular weight polyethylene wire; the twist of the first yarn is 500-800 twists / m; the second yarn includes a 20-40D spandex core wire and a 50-100D second covering wire coated on the spandex core wire; the third yarn is a 100-150D polyester yarn. The first covering wire and the second covering wire can use nylon wire, polyester wire, polypropylene wire or acrylic wire as covering wires, and preferably, the first covering wire and the second covering wire use the same wire. The high-density safety area 4 has the function of anti-cutting and wear-resisting, and its wear resistance can reach EN388 wear resistance level 4, and its anti-cutting performance can reach EN388 cut resistance level 5. The low-density tearable area 3 serves as a basic connection, which can be torn by tension in the event of an emergency entrapment accident, and the hand can be quickly withdrawn.
[0051] To evaluate the safety of gloves, you can refer to "ASTM D412-16 (2021) Standard Test Method for Tension of Vulcanized Rubber and Thermoplastic Elastomers" to test the breaking force of gloves. The smaller the breaking force, the higher the safety, that is, the gloves are easier to tear and the hands are easier to get out of the way when an accident occurs. For example, for ordinary dipped gloves without tearable area 3, hydrophobic pretreatment and dipped gloves, Figure 1c The tensile strength of the gloves without the safety reinforcement structure and the gloves with the safety reinforcement structure are tested, wherein the lower clamp clamps the palm part and the upper clamp clamps the tip of the middle finger. The tensile strength of the tested gloves when they are torn is shown in Table 1.
[0052] Table 1 Gloves breaking force test table
[0053] Tearable area Sawtooth connection structure Reinforcement ring Breaking force / N none none none 291.8 have none none 81.5 have V-Shape none 72.3 have Wave none 73.9 have none have 71.5
[0054] It can be seen from Table 1 that the breaking force of the gloves with tearable area 3 and no safety reinforcement structure is about 82N, which is much lower than the breaking force of 291.8N of ordinary nitrile dipped gloves. After the safety reinforcement structure is set in the tearable area 3 and the safety area 4, the breaking force of the gloves is further reduced to about 72N. The safety reinforcement structure is more conducive to tearing and breaking the tearable area 3. In normal use, the gloves are not easy to tear off and are easy to put on and take off. In the event of mechanical pinching, the gloves can be torn more easily and the hands can be quickly pulled out. They have excellent anti-slip properties and good comfort.
[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
