Description
Technical Field
[0001] The utility model relates to the technical field of protective articles, in particular to a pair of safety gloves with a coating which are easy to put on and take off. Background Art
[0002] In many mechanical processing operations, there are often operating scenes such as rollers and conveyor belts. 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. At the same time, metal cutting fluid splashes onto the hands, causing redness, swelling and even ulceration of the skin. In response to the above problems, it is very necessary to design a glove that is easy to put on and take off and has high-performance mechanical protection. Utility Model Content
[0003] In order to solve the above technical problems, the utility model provides a safety glove with a coating that is easy to put on and take off. The glove has a tearable area and a safety area. The tearing force of the tearable area is smaller than the tearing force of the safety area. A first coating is arranged in the safety area, and a second coating is arranged in the tearable area. When the first coating is dipped, the second coating is separated from the first coating to prevent the first coating from adhering to the tearable area and affecting the easy tearing performance of the tearable area, so that the tearable area can be easily torn and pulled apart.
[0004] The utility model solves the technical problem by adopting the following technical solutions:

[0021] 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.
[0022] 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.
[0023] The utility model provides a safety glove with a coating that is easy to put on and take off, referring to Figure 1 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 smaller than the tearing force of the safety area 4; the outer surface of the safety area 4 is provided with a first coating 5; the outer surface of the tearable area 3 is provided with a second coating 6 different from the first coating 5, and the tearing force of the second coating 6 is smaller than the tearing force of the first coating 5.
[0024] The breaking force of the tearable area 3 of the glove is smaller than that of the safety area 4, so that when the glove is entangled in the machine, it can be easily torn and pulled apart from the tearable area 3 pre-set at the fingers or palms, 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.
[0025] According to the functional requirements of the gloves, the safety area 4 of the gloves usually needs to be provided with a first coating 5. Preferably, the first coating 5 is a wear-resistant layer, which can improve the wear resistance and durability of the gloves. For example, the first coating 5 can be made of wear-resistant materials such as nitrile rubber, latex or polyurethane. Generally, the first coating 5 is made by dipping the gloves in a glue solution of the wear-resistant material, making the glue solution adhere to the safety area 4 and then drying it, so that the wear-resistant material is bonded and fixed to the safety area 4. In order to prevent the glue solution of the first coating 5 from adhering to the tearable area 3 when the gloves are dipped in the glue solution of the first coating 5, a second coating 6 different from the first coating 5 can be pre-set on the outer surface of the tearable area 3 before dipping the glue solution of the first coating 5, so as to form a mask on the tearable area 3. Specifically, the second coating 6 can be directly applied to the outer surface of the tearable area 3 of the glove, or the yarn of the tearable area 3 can be pre-soaked in the slurry of the second coating 6 to form the second coating 6 on the yarn surface, and then the yarn with the second coating 6 is used to weave the tearable area 3. In this way, when the gloves are dipped, the mask formed by the second coating 6 can isolate the glue of the first coating 5, and the glue of the first coating 5 will not adhere to the tearable fabric area after the hydrophobic treatment, and the outer surface of the tearable area 3 will not be affected by the adhesion of the tearable area 3 by the glue. At the same time, the second coating 6 forms a thinner mask on the tearable area 3, and its own breaking force is smaller than the breaking force of the first coating 5, so the second coating 6 has little effect on the breaking force of the tearable area 3.
[0026] The solvent of the glue solution for making the first coating 5 is mostly an aqueous solvent, and the first coating 5 is an aqueous functional coating. Accordingly, the second coating 6 is a hydrophobic layer, which can also play a waterproof role when the gloves are used. When the solvent of the glue solution for making the first coating 5 is an oily solvent, the first coating 5 is an oily functional coating, and accordingly, the second coating 6 is an oleophobic layer.
[0027] When the gloves are dipped in glue, the finger portion 1 and the palm portion 2 are generally dipped in the glue, and the wrist portion 7 may not be immersed in the glue. According to needs, the safety area 4 may be fully dipped in glue, or partially dipped in glue, such as 1 / 2 dipping, 2 / 3 dipping, 3 / 4 dipping, etc., so that the first coating 5 covers the outer surface of part of the safety area 4. Similarly, the second coating 6 may be provided on the outer surface of the safety area 4 not covered by the first coating 5 to prevent the glue of the first coating 5 from adhering to the part of the safety area 4 that does not need to be dipped in glue during dipping.
[0028] 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 less than that of the safety area 4. Preferably, the tearing force of the tearable area 3 is 20%-50% of the tearing 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 tearing force of the tearable area 3 does not exceed 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 weaving and the woven thickness can be set as needed. In order to maintain wearing comfort, the inner surface of the glove is kept flat during weaving.
[0029] In one embodiment, the safety area 4 is formed by weaving the first yarn and the second yarn, and can be formed by twisting the first yarn and the second yarn and then weaving them, or can be formed by weaving U2, with the second yarn inside and the first yarn outside; the tearable area 3 is formed by weaving the second yarn, and the tearable area 3 is smaller in density and weaker than the safety area 4, and is easier to tear and break.
[0030] 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, polyester, polypropylene or acrylic 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 cut resistance and wear resistance, and the cut resistance performance can reach EN388 cut resistance level 5. After the nitrile rubber coating is set, the wear resistance can reach EN388 wear resistance level 4; the low-density tearable area 3 plays a basic connection role, and can be torn by tension in the event of an emergency clamping accident, and the hand can be quickly pulled out.
[0031] 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 knuckle of the four fingers; and / or, the tearable area 3 is arranged at the second knuckle 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 portion 7.
[0032] 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 glove and the flexibility of hand operation. According to 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 7. 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.
[0033] 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, refer to Figure 1As 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 involved in the device, it can be torn and pulled off 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. The tearable area 3 can also be arranged on the palm part 2 at the same time. For example, when the back of the palm part is involved in the device during the hand grasping operation, it can be torn and pulled off from the tearable area 3 arranged on the palm part 2, so that the fingers can be easily pulled out of the glove, especially when the wrist part 7 of the glove is relatively long, the time of pulling the hand out of the wrist part 7 can be saved. In order to improve the comfort of use and strengthen the protection effect, the tearable area 3 can also be arranged on each knuckle of each finger part 1. For example, when handling metal processing and other work involving rotation and rolling, once the front section of the glove is entangled in the machine, the glove can be quickly torn and the user's hand can be pulled out immediately to prevent major accidents such as mechanical crushing.
[0034] In order to improve the comfort of using the gloves, the width of the tearable area 3 is set to 3-5mm, which is conducive to the movement of the 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 second coating 6.
[0035] Generally, the first joint of the thumb and the second joint of the fourth finger have greater mobility, so the width of the tearable area 3 set at the first joint of the thumb and the second joint of the fourth finger is greater than the width of other tearable areas 3, or multiple groups of tearable areas 3 are set at the first joint of the thumb and the second joint of the fourth finger, preferably, two groups are set, 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.
[0036] 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.
[0037] 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 detach in the event of a pinching accident. For example, the breaking force of ordinary dipped gloves without tearable area 3, dipped gloves without hydrophobic pretreatment, and dipped gloves with hydrophobic pretreatment are tested, where the lower clamp clamps the palm and the upper clamp clamps the tip of the middle finger. The breaking force of the tested gloves is shown in Table 1.
[0038] Table 1 Gloves breaking force test table
[0039] Tearable area Hydrophobic pretreatment Dipping Breaking force / N none none yes 291.8 have none have 101.5 have have have 81.5
[0040] As can be seen from Table 1, when the gloves with tearable area 3 and no hydrophobic pretreatment are worn on the hand model and immersed in the glue, the safety area 4 and the tearable area 3 are both immersed in the glue, and the breaking force is about 100N. Although it is much lower than the breaking force of 291.8N of ordinary nitrile dipped gloves, it is still quite laborious to break. After the tearable area 3 is hydrophobic pretreatment and not immersed in the glue, the breaking force of the gloves is reduced to about 80N, which 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 hand can be quickly pulled out. They have excellent anti-slip properties and good comfort.
[0041] 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.
