Description

Technical Field

[0001] This invention relates to the field of suede preparation technology, and in particular to a suede structure for abrasion-resistant gloves and its preparation process. Background Technology

[0002] Suede is a general term for leather with a fine, napped surface. It includes suede with some or all of the grain removed (for the front) and nubuck (for the flesh side). It is mostly made from pigskin, cowhide, and sheepskin using the chrome tanning method. Suede is only napped and dyed, without any finishing. It has good hygiene properties but is not easy to maintain. However, its common qualities are fine and even nap, colorfastness, good water resistance, and no greasy feel. Therefore, it is widely used to make suede, clothing, and gloves.

[0003] Gloves are used for hand warmth or occupational protection. As technology advances, people's demands for hand safety and comfort have increased, leading to higher requirements for gloves. Consequently, the structure and design of gloves need to be continuously updated and improved to meet the expectations and needs of users, addressing various issues such as wearing comfort, anti-static properties, and abrasion resistance.

[0004] Chinese Patent Publication No. CN202247481U, published on May 30, 2012, discloses a high-abrasion-resistant microfiber suede, comprising a base layer composed of bundled microfibers, the surface of which is covered with an organosilicon film. The drawback of this technical solution is that while the high-abrasion-resistant microfiber suede undergoes hydrophobic and lubricating treatments to make its structure more compact, pressure-resistant, and abrasion-resistant, thus improving material stability, and utilizes the high-density nylon bundled microfibers and the internal polyurethane foam coated with abrasion-resistant particles to ensure abrasion resistance, the structure lacks corresponding design for limiting the base layer and the organosilicon film. It can only be considered a common sewing and bonding method. Therefore, during use, external forces can cause the base layer and the organosilicon film to detach, directly affecting the performance of the suede.

[0005] In summary, a structure can be designed to reduce the probability of separation between the substrate layer and the silicone film layer, thereby ensuring the performance of suede. Summary of the Invention

[0006] The present invention aims to overcome the shortcomings of the prior art in not making further connection structures for the limiting connection between the base layer and the organosilicon film layer, and provides a structure for wear-resistant suede gloves and its preparation process that can reduce the probability of suede becoming loose due to external forces.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A suede structure for abrasion-resistant gloves includes a base layer and two abrasion-resistant layers. The base layer has two abrasion-resistant grooves symmetrically distributed at its upper and lower ends. Several abrasion-resistant blocks are installed on the base layer, evenly distributed between the two abrasion-resistant grooves. The two abrasion-resistant layers are symmetrically distributed with the base layer as the base layer, and the abrasion-resistant layers match the abrasion-resistant grooves.

[0009] This design allows the base layer and two wear-resistant layers to be connected to form a suede-like material. The base layer has two wear-resistant grooves, symmetrically distributed at its upper and lower ends. Several wear-resistant blocks are also installed on the base layer, not only evenly distributed but also positioned between the two wear-resistant grooves. This ensures the two wear-resistant layers are symmetrically distributed with the base layer as the foundation, and the wear-resistant layers are matched to the wear-resistant grooves. Therefore, when connecting the wear-resistant layers and the base layer, the wear-resistant layers can be moved and pressed down towards the wear-resistant grooves until they meet, at which point the connection is completed. In this way, when using a suede structure composed of a wear-resistant layer and a base layer, the base layer is not only protected by the wear-resistant layer to prevent damage when subjected to external forces, but the wear-resistant blocks on the base layer also alleviate the external forces caused by friction. Of course, the wear-resistant grooves here further limit the wear-resistant layer. Together with the connection between the wear-resistant layer and the base layer, this enhances the mutual limiting effect between the wear-resistant layer and the base layer, reducing the possibility of the wear-resistant layer and the base layer separating under the action of external forces. This reduces the probability of the suede becoming loose due to external forces.

[0010] Preferably, a hard wear-resistant block and an insert are installed on the wear-resistant layer. The hard wear-resistant block is fitted onto the top of the wear-resistant layer, and the insert is placed at the bottom of the wear-resistant layer. The position of the insert corresponds vertically to the position of the hard wear-resistant block, and the insert matches the wear-resistant groove. This design, by installing the hard wear-resistant block and the insert on the wear-resistant layer—the hard wear-resistant block fitting onto the top of the wear-resistant layer and the insert at the bottom—allows the hard wear-resistant block to be placed at the outer end of the suede and the insert at the inner end of the suede when connecting the wear-resistant layer and the base layer. The position of the insert corresponds vertically to the position of the hard wear-resistant block, and the insert matches the wear-resistant groove. In other words, when connecting the wear-resistant layer and the base layer, the insert needs to be inserted into the wear-resistant groove. The cooperation between the wear-resistant groove and the insert ensures proper positioning of the wear-resistant layer and the base layer. In this way, when using the installed and connected suede, external objects can first come into contact with the hard abrasion-resistant block, reducing the probability of damage caused by external objects contacting the abrasion-resistant layer. When an external object comes into contact with the hard abrasion-resistant block, the hard abrasion-resistant block will sense the external force applied by the external object. With the arrangement of the insert and the hard abrasion-resistant block, the insert can concentrate the external force and embed it into the base layer, that is, concentrate the force at the abrasion groove. With the abrasion-resistant block, the force can be smoothly discharged to protect the suede and reduce the probability of the suede loosening due to external forces.

[0011] Preferably, the substrate layer is provided with a number of slots, which are symmetrically distributed at the front and rear ends of the wear-resistant groove. The slots are connected to the wear-resistant groove. The insert is equipped with a number of limiting blocks, which are symmetrically distributed at the front and rear ends of the insert. The limiting blocks correspond one-to-one with the slots, and the limiting blocks are detachably connected to the insert. This design incorporates several slots symmetrically distributed at both ends of the wear-resistant groove on the substrate layer, all of which are connected to the groove. Several limiting blocks, also symmetrically distributed at both ends, are installed on the insert. When the wear-resistant layer moves towards the substrate layer—that is, when the insert is inserted into the wear-resistant groove—the position of the limiting blocks corresponds to the position of the slots. These limiting blocks are detachably connected to the insert, allowing for immediate manipulation to insert them into the slots. This further enhances the connection and limiting function between the insert and the substrate layer, ensuring the insert is more stably positioned within the wear-resistant groove. This also strengthens the connection between the wear-resistant layer and the substrate layer, reducing the probability of them separating under external forces.

[0012] Preferably, the limiting block has a convex cross-sectional shape, with the width of its rear end greater than its front end, and the slot matches the front end of the limiting block. This design, by setting the limiting block's cross-sectional shape to a convex shape and ensuring the rear end is wider than the front end, along with the slot matching the front end, enhances the mutual limiting effect between the limiting block and the slot when the limiting block is inserted into the slot. This reduces the probability of external force causing the limiting block to disengage from the slot.

[0013] Preferably, the wear-resistant block has a cavity, and wear-resistant particles and fire-retardant particles are installed on the wear-resistant block. Each type of particle comprises a plurality of wear-resistant particles and fire-retardant particles. The wear-resistant particles are evenly distributed on the outer surface of the wear-resistant block, and the fire-retardant particles are fitted inside the cavity. This design, by providing a cavity in the wear-resistant block, allows for the installation of multiple wear-resistant and fire-retardant particles. The wear-resistant particles are evenly distributed on the outer surface of the wear-resistant block, while the fire-retardant particles are fitted inside the cavity. Thus, when the suede is subjected to external force, the wear-resistant layer is pressed down towards the base layer; that is, when the insert is pressed against the wear-resistant groove, the insert first contacts the wear-resistant particles, reducing the probability of damage to the wear-resistant block due to contact and compression from the insert. Furthermore, the arrangement of the fire-retardant particles inside the cavity of the wear-resistant block also prevents the wear-resistant block from being directly flattened by the compression of the insert, thereby affecting the working and practical effect of the base layer. At the same time, the wear-resistant block, under the influence of extrusion pressure, can also squeeze the fireproof particles out of the cavity and place them in the matrix layer to enhance the fireproof effect of the matrix layer.

[0014] Preferably, the wear-resistant block has several evenly distributed limiting holes, with the wear-resistant particles positioned between adjacent limiting holes. This design, with its evenly distributed limiting holes and wear-resistant particles positioned between them, increases the probability of contact between the wear-resistant particles and the insert when the wear-resistant layer is subjected to external pressure (i.e., when the insert is subjected to external pressure), reducing the probability of damage to the wear-resistant block due to contact and pressure from the insert. Of course, these limiting holes also allow the fire-retardant particles within the cavity of the wear-resistant block to be squeezed out under pressure, thus enhancing the fire-retardant effect of the base layer, or more specifically, enhancing the fire-retardant effect of the suede.

[0015] Preferably, a limiting mesh is installed on the limiting hole. The upper end of the limiting mesh is connected to the outer surface of the wear-resistant block, and the lower end is connected to the inner surface of the wear-resistant block. The limiting mesh has several mesh holes, and the diameter of the fire-retardant particles is larger than the diameter of the mesh holes. This design, by installing the limiting mesh on the limiting hole, with the upper end connected to the outer surface of the wear-resistant block and the lower end connected to the inner surface of the wear-resistant block, effectively blocks the limiting hole, thereby reducing the probability of the fire-retardant particles in the cavity automatically escaping without external force. Furthermore, the limiting mesh has several mesh holes, and the diameter of the fire-retardant particles is larger than the diameter of the mesh holes, which enhances the blocking effect of the limiting mesh on the fire-retardant particles. Only when the wear-resistant block is subjected to compression, and the fire-retardant particles inside the wear-resistant block are affected by the force, can they break through the limiting mesh and detach from the cavity, thus enhancing the fire-retardant effect of the suede.

[0016] Preferably, the wear-resistant groove includes an opening and a bottom. The insert block is inserted into the wear-resistant groove through the opening, and its upper and lower ends are respectively positioned at the bottom of the two grooves. This design allows the insert block to be smoothly inserted into the wear-resistant groove through the opening, and the upper and lower ends of the wear-resistant block can be positioned at the bottom of the two grooves respectively. Thus, under the action of external force, the insert block can first contact the wear-resistant particles on the wear-resistant block, so that the external force can work in conjunction with the cavity of the wear-resistant block.

[0017] Preferably, a limiting band one and a limiting band two are fitted onto the outer edge of the base layer. The limiting band one is positioned at the junction of the upper end of the base layer and a wear-resistant layer, while the limiting band two is positioned at the junction of the lower end of the base layer and another wear-resistant layer. This design, by fitting the limiting band one and the limiting band two onto the outer edge of the base layer, with the limiting band one positioned at the junction of the upper end of the base layer and a wear-resistant layer, and the limiting band two positioned at the junction of the lower end of the base layer and another wear-resistant layer, not only reduces the probability of the suede separating from the base layer and the wear-resistant layer under external force, but also prevents foreign objects from touching the junction of the upper end of the base layer and a wear-resistant layer, as well as the junction of the lower end of the base layer and another wear-resistant layer, thus preventing damage.

[0018] This invention also provides a process for preparing a suede structure for abrasion-resistant gloves, specifically including the following steps:

[0019] Step 1: Make the wear-resistant block. First, make limiting holes and cavities on the wear-resistant block. Then, inject fireproof particles into the cavity. Install wear-resistant particles on the outer surface of the wear-resistant block. Then, install the upper limit net to limit the holes.

[0020] Step 2: Install the completed wear-resistant block onto the substrate layer, and make wear-resistant grooves at the top and bottom of the substrate layer respectively. The top and bottom of the wear-resistant block are placed at the bottom of the two wear-resistant grooves respectively, and slots are symmetrically made at the front and back ends of the wear-resistant grooves. This completes the production of the substrate layer.

[0021] Step 3: Install a hard wear-resistant block on the top of the wear-resistant layer, and install an insert block at the bottom of the wear-resistant layer. The front and rear ends of this insert block need to be equipped with limit blocks. The limit blocks are not only detachably connected to the insert block, but also correspond one-to-one with the slot. This completes the production of the wear-resistant layer.

[0022] Step 4: Control the wear-resistant layer, allowing the insert block to pass through the slot and be placed inside the wear-resistant groove. Next, the limiting block can be controlled to be inserted into the slot, thus initially completing the limiting work of the wear-resistant layer. Then, the sewing and bonding work of the wear-resistant layer and the base layer is carried out. Finally, control the limiting band one and the limiting band two, so that the limiting band one is fitted at the upper end of the base layer and the connection between one wear-resistant layer, and the limiting band two is placed at the lower end of the base layer and the connection between another wear-resistant layer, thus completing the connection and installation work of the wear-resistant layer and the base layer.

[0023] The beneficial effects of this invention are: it can reduce the probability of suede becoming loose due to external forces; it facilitates the smooth operation of the wear-resistant layer and the base layer; and it has the effect of assisting external forces. Attached Figure Description

[0031] The invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 In the illustrated embodiment, a suede structure for abrasion-resistant gloves includes a base layer 1 and two abrasion-resistant layers 2. The base layer 1 has two abrasion-resistant grooves 4 symmetrically distributed at its upper and lower ends. Several abrasion-resistant blocks 5 are evenly distributed on the base layer 1, positioned between the two abrasion-resistant grooves 4. The two abrasion-resistant layers 2 are symmetrically distributed vertically with the base layer 1 as the base, and the abrasion-resistant layers 2 are matched with the abrasion-resistant grooves 4. Hard abrasion-resistant blocks 3 and inserts 6 are installed on the abrasion-resistant layers 2. The hard abrasion-resistant blocks 3 are fitted onto the top of the abrasion-resistant layer 2, and the inserts 6 are placed at the bottom of the abrasion-resistant layer 2. The positions of the inserts 6 correspond vertically to the positions of the hard abrasion-resistant blocks 3, and the inserts 6 are matched with the abrasion-resistant grooves 4. The substrate layer 1 has several slots 8, which are symmetrically distributed at both ends of the wear-resistant groove 4. The slots 8 are connected to the wear-resistant groove 4. The insert block 6 is equipped with several limiting blocks 7, which are symmetrically distributed at both ends of the insert block 6. Each limiting block 7 corresponds to one of the slots 8, and the limiting blocks 7 and the insert block 6 are detachably connected. The limiting block 7 has a convex cross-sectional shape, and the width of the rear end of the limiting block 7 is greater than the width of the front end. The slots 8 match the front end of the limiting block 7.

[0033] like Figure 2 , Figure 5 and Figure 6 As shown, the wear-resistant block 5 has a cavity 11. Wear-resistant particles and fire-retardant particles 12 are installed on the wear-resistant block 5. Each type of wear-resistant particle and fire-retardant particle 12 consists of a plurality of particles. The wear-resistant particles are evenly distributed on the outer surface of the wear-resistant block 5, and the fire-retardant particles 12 are fitted into the cavity 11. The wear-resistant block 5 has a plurality of limiting holes 9, which are evenly distributed. The wear-resistant particles are placed between adjacent limiting holes 9. A limiting mesh 10 is installed on the limiting holes 9. The upper end of the limiting mesh 10 is connected to the outer surface of the wear-resistant block 5, and the lower end of the limiting mesh 10 is connected to the inner surface of the wear-resistant block 5. The limiting mesh 10 has a plurality of mesh holes, and the diameter of the fire-retardant particles 12 is larger than the diameter of the mesh holes.

[0034] like Figure 1 , Figure 2 and Figure 3As shown, the wear-resistant groove 4 includes a groove opening and a groove bottom. The insert block 6 is inserted into the wear-resistant groove 4 through the groove opening. The upper and lower ends of the wear-resistant block 5 are respectively placed at the two groove bottoms. Limiting band one 13 and limiting band two 14 are fitted on the outer edge of the substrate layer 1. Limiting band one 13 is placed at the upper end of the substrate layer 1 and the connection between it and a wear-resistant layer 2. Limiting band two 14 is placed at the lower end of the substrate layer 1 and the connection between it and another wear-resistant layer 2.

[0035] This invention also provides a process for preparing a suede structure for abrasion-resistant gloves, specifically including the following steps:

[0036] Step 1: Make the wear-resistant block 5. First, make the limiting hole 9 and cavity 11 on the wear-resistant block 5. Then, inject fireproof particles 12 into the cavity 11. Install the wear-resistant particles on the outer surface of the wear-resistant block 5. Then, the upper limit net 10 can be installed to limit the limiting hole 9.

[0037] Specifically, the process involves several steps. First, the wear-resistant block 5 needs to be manufactured. This block must withstand external crushing without breaking. Furthermore, the air pressure within the cavity 11 of the wear-resistant block 5 and the fire-retardant particles 12 must be compressed to allow the particles to be extruded. The material for the wear-resistant block 5 can be a soft, elastic rubber. The fire-retardant particles 12 are primarily composed of red phosphorus flame retardant, a mixture of magnesium hydroxide and aluminum hydroxide. Red phosphorus flame retardant is chosen for its high flame-retardant efficiency and low dosage. It has low smoke emission and low toxicity. When used in conjunction with magnesium hydroxide and aluminum hydroxide flame retardants, it can produce a synergistic effect and achieve a good flame retardant effect. On the wear-resistant block 5, it is necessary to open the limiting holes 9 and the cavity 11. There are several limiting holes 9, which are not only connected to the cavity 11, but also evenly distributed on the outer surface of the wear-resistant block 5. These limiting holes 9 are symmetrically distributed with the center of the wear-resistant block 5 as the base point, which increases the range of gas inlet and outlet channels inside and outside the wear-resistant block 5, and also makes the gas inlet and outlet state balanced. At the same time, fire-retardant particles 12 need to be placed inside the wear-resistant block 5 in advance to fill the cavity 11 of the wear-resistant block 5. Then, an upper limit net 10 is installed on the limiting hole 9 to limit the hole 9. The upper end of the limiting net 10 is connected to the outer side of the wear-resistant block 5, and the lower end is connected to the inner side of the wear-resistant block 5. The diameter of the mesh on the limiting net 10 is smaller than the diameter of the fire-retardant particles 12. This can prevent the fire-retardant particles 12 from automatically and randomly passing through the mesh of the limiting net 10 and leaving the cavity 11. Of course, the material of the limiting net 10 can still be soft rubber. The thickness of the soft rubber of the limiting net 10 needs to be smaller than the thickness of the soft rubber of the wear-resistant block 5. In this way, when the wear-resistant block 5 is squeezed, the cavity 11 is affected by air pressure and external force, and the space gradually decreases. The fire-retardant particles 12 will be pushed by the pressure, thereby breaking through the limiting net 10 and leaving the cavity 11, sticking to the base layer 1 to play a fireproof protection role for the base layer 1. Of course, there are several wear-resistant particles evenly distributed on the outer surface of the wear-resistant block 5. These wear-resistant particles can be made of hard rubber. Moreover, the distance between the wear-resistant particles and the inner surface of the wear-resistant block 5 can be greater than the distance between the outer and inner surfaces of the wear-resistant block 5. Under the action of external force, the insert block 6 will touch the wear-resistant particles first, so as to reduce the probability of the wear-resistant block 5 being damaged by friction.

[0038] Step 2: Install the completed wear-resistant block 5 onto the base layer 1, and make wear-resistant grooves 4 at the top and bottom of the base layer 1 respectively. The top and bottom of the wear-resistant block 5 are placed at the bottom of the two wear-resistant grooves 4 respectively, and slots 8 are symmetrically made at the front and back ends of the wear-resistant grooves 4. This completes the production of the base layer 1.

[0039] Specifically, after the wear-resistant block 5 is made, it can be installed on the base layer 1. Wear-resistant grooves 4 are opened at the top and bottom ends of the base layer 1, and the top and bottom ends of the wear-resistant block 5 are placed at the bottom of the two wear-resistant grooves 4 respectively. At the same time, slots 8 need to be symmetrically opened at the front and back ends of the wear-resistant grooves 4. These slots 8 are connected to the wear-resistant grooves 4.

[0040] Step 3: Install the hard wear-resistant block 3 on the top of the wear-resistant layer 2, and install the insert block 6 at the bottom of the wear-resistant layer 2. The front and rear ends of the insert block 6 need to be equipped with limiting blocks 7. The limiting blocks 7 are not only detachably connected to the insert block 6, but also correspond one-to-one with the slot 8. In this way, the work of making the wear-resistant layer 2 is completed.

[0041] Specifically, the next step is to install a hard wear-resistant block 3 on the top of the wear-resistant layer 2, and an insert block 6 is installed at the bottom of the wear-resistant layer 2. This hard wear-resistant block 3 needs to withstand the friction caused by external objects. It can be made of wear-resistant stainless steel, which is not only hard and not easily damaged, but can also be fitted onto the soft wear-resistant layer 2 for stitching. The insertion block 6 is positioned vertically opposite to the hard wear-resistant block 3 and matches the wear-resistant groove 4. This allows the insertion block 6 to be inserted into the wear-resistant groove 4 through its opening under the force applied to the hard wear-resistant block 3. This ensures that the end of the wear-resistant block 5 at the bottom of the groove 4 contacts the insertion block 6. Limiting blocks 7 need to be installed at both ends of the insertion block 6. Both the insertion block 6 and the limiting blocks 7 can be made of polyurethane, which has high strength, high wear resistance, and solvent resistance. Therefore, it will not come into contact with liquids (flame retardants are generally solid at room temperature, while magnesium hydroxide and aluminum hydroxide are precipitates; a mixture of these three forms a powdery solid, thus not affecting the polyurethane). Melting ensures that even if external liquid water seeps in, it will not affect the polyurethane. Of course, the connection between the limiting block 7 and the insert block 6 can be made by a compression spring to control the limiting block 7. The limiting block 7 not only needs to correspond one-to-one with the slot 8, but also has a convex cross-section. The width of the rear end of the limiting block 7 is greater than the width of the front end. The slot 8 matches the front end of the limiting block 7. Thus, after controlling the length of the two limiting blocks 7, the front end of the limiting block 7 can be inserted into the slot 8. With the cooperation of the limiting block 7 and the slot 8, the limiting work of the insert block 6 and the base layer 1 is performed, which prevents the insert block 6 from automatically detaching from the wear-resistant groove 4, thereby preventing the wear-resistant layer 2 and the base layer 1 from separating.

[0042] Step 4: Control the wear-resistant layer 2, allowing the insert block 6 to pass through the slot and be placed in the wear-resistant groove 4. Next, the limiting block 7 can be controlled to be inserted into the slot 8, thus initially completing the limiting work of the wear-resistant layer 2. Then, the sewing and bonding work of the wear-resistant layer 2 and the base layer 1 is carried out. Finally, control the limiting band 13 and the limiting band 2 14, so that the limiting band 13 is fitted on the upper end of the base layer 1 and the connection point of one wear-resistant layer 2, and the limiting band 2 14 is placed on the lower end of the base layer 1 and the connection point of another wear-resistant layer 2, thus completing the connection and installation work of the wear-resistant layer 2 and the base layer 1.

[0043] Specifically, under the control of the insert 6, the insert 6 passes through the groove of the wear-resistant groove 4 and is inserted into the wear-resistant groove 4, thereby controlling the length of the two limiting blocks 7 so that the limiting blocks 7 can be inserted into the slot 8. This is the initial work of limiting the wear-resistant layer 2. Then, the sewing and bonding work of the wear-resistant layer 2 and the base layer 1 can be carried out. This is a common connection work for suede, so there is no special attention required. However, the two wear-resistant layers 2 are symmetrically distributed on the base layer 1, that is, there are contact points between the upper end of the wear-resistant layer 2 and the upper end of the base layer 1, and between the lower end of the wear-resistant layer 2 and the lower end of the base layer 1. In order to reduce the possibility of the wear-resistant layer 2 and the base layer 1 separating under the action of external force, it is necessary to perform bonding work between the wear-resistant layer 2 and the base layer 1. After sewing and bonding, upper limit band 13 is fitted at the upper connection between the upper wear-resistant layer 2 and the base layer 1, and upper limit band 24 is fitted at the lower connection between the lower wear-resistant layer 2 and the base layer 1. This further ensures the connection between the wear-resistant layer 2 and the base layer 1. The upper limit band 13 and the upper limit band 24 can also be made of elastic soft rubber to control the loop area of ​​the upper limit band 13 and the loop area of ​​the upper limit band 24, so as to fit the connection between the wear-resistant layer 2 and the base layer 1.

[0044] First, the wear-resistant block 5 needs to be manufactured. This wear-resistant block 5 needs to withstand external crushing without breaking. Furthermore, the air pressure within the cavity 11 of the wear-resistant block 5 and the fire-retardant particles 12 need to be compressed so that the fire-retardant particles 12 can be extruded outwards. The material for the wear-resistant block 5 can be a soft, elastic rubber. The fire-retardant particles 12 are made primarily of red phosphorus flame retardant, a mixture of magnesium hydroxide and aluminum hydroxide. Red phosphorus flame retardant is chosen because it has high flame-retardant efficiency, requires only a small amount, and produces a rapid flame. With low smoke production and low toxicity, it can produce a synergistic effect when used in conjunction with magnesium hydroxide and aluminum hydroxide flame retardants to achieve a good flame retardant effect. On the wear-resistant block 5, it is necessary to open the limiting holes 9 and the cavity 11. There are several limiting holes 9, which are not only connected to the cavity 11, but also evenly distributed on the outer surface of the wear-resistant block 5. These limiting holes 9 are symmetrically distributed with the center of the wear-resistant block 5 as the base point, which increases the range of gas inlet and outlet channels inside and outside the wear-resistant block 5, and also makes the gas inlet and outlet state balanced. At the same time, fire-retardant particles 12 need to be placed inside the wear-resistant block 5 in advance to fill the cavity 11 of the wear-resistant block 5. Then, an upper limit net 10 is installed on the limiting hole 9 to limit the hole 9. The upper end of the limiting net 10 is connected to the outer side of the wear-resistant block 5, and the lower end is connected to the inner side of the wear-resistant block 5. The diameter of the mesh on the limiting net 10 is smaller than the diameter of the fire-retardant particles 12. This can prevent the fire-retardant particles 12 from automatically and randomly passing through the mesh of the limiting net 10 and leaving the cavity 11. Of course, the material of the limiting net 10 can still be soft rubber. The thickness of the soft rubber of the limiting net 10 needs to be smaller than the thickness of the soft rubber of the wear-resistant block 5. In this way, when the wear-resistant block 5 is squeezed, the cavity 11 is affected by air pressure and external force, and the space gradually decreases. The fire-retardant particles 12 will be pushed by the pressure, thereby breaking through the limiting net 10 and leaving the cavity 11, sticking to the base layer 1 to play a fireproof protection role for the base layer 1. Of course, there are several wear-resistant particles evenly distributed on the outer surface of the wear-resistant block 5. These wear-resistant particles can be made of hard rubber. Moreover, the distance between the wear-resistant particles and the inner surface of the wear-resistant block 5 can be greater than the distance between the outer and inner surfaces of the wear-resistant block 5. Under the action of external force, the insert block 6 will touch the wear-resistant particles first, so as to reduce the probability of the wear-resistant block 5 being damaged by friction.

[0045] After the wear-resistant block 5 is made, it can be installed on the base layer 1. Wear-resistant grooves 4 are opened at the top and bottom ends of the base layer 1, and the top and bottom ends of the wear-resistant block 5 are placed at the bottom of the two wear-resistant grooves 4 respectively. At the same time, slots 8 need to be symmetrically opened at the front and back ends of the wear-resistant grooves 4. These slots 8 are connected to the wear-resistant grooves 4.

[0046] Next, a hard wear-resistant block 3 needs to be fitted onto the top of the wear-resistant layer 2, and an insert block 6 needs to be installed at the bottom of the wear-resistant layer 2. This hard wear-resistant block 3 needs to withstand the friction caused by the contact of external objects. It can be made of wear-resistant stainless steel, which is not only hard and not easily damaged, but can also be fitted onto the soft wear-resistant layer 2 for stitching. The insertion block 6 is positioned vertically opposite to the hard wear-resistant block 3 and matches the wear-resistant groove 4. This allows the insertion block 6 to be inserted into the wear-resistant groove 4 through its opening under the force applied to the hard wear-resistant block 3. This ensures that the end of the wear-resistant block 5 at the bottom of the groove 4 contacts the insertion block 6. Limiting blocks 7 need to be installed at both ends of the insertion block 6. Both the insertion block 6 and the limiting blocks 7 can be made of polyurethane, which has high strength, high wear resistance, and solvent resistance. Therefore, it will not come into contact with liquids (flame retardants are generally solid at room temperature, while magnesium hydroxide and aluminum hydroxide are precipitates; a mixture of these three forms a powdery solid, thus not affecting the polyurethane). Melting ensures that even if external liquid water seeps in, it will not affect the polyurethane. Of course, the connection between the limiting block 7 and the insert block 6 can be made by a compression spring to control the limiting block 7. The limiting block 7 not only needs to correspond one-to-one with the slot 8, but also has a convex cross-section. The width of the rear end of the limiting block 7 is greater than the width of the front end. The slot 8 matches the front end of the limiting block 7. Thus, after controlling the length of the two limiting blocks 7, the front end of the limiting block 7 can be inserted into the slot 8. With the cooperation of the limiting block 7 and the slot 8, the limiting work of the insert block 6 and the base layer 1 is performed, which prevents the insert block 6 from automatically detaching from the wear-resistant groove 4, thereby preventing the wear-resistant layer 2 and the base layer 1 from separating.

[0047] Under the control of the insert 6, the insert 6 passes through the groove of the wear-resistant groove 4 and is inserted into the wear-resistant groove 4, thereby controlling the length of the two limiting blocks 7 so that the limiting blocks 7 can be inserted into the slot 8. This is the initial work of limiting the wear-resistant layer 2. Then, the sewing and bonding work of the wear-resistant layer 2 and the base layer 1 can be carried out. This is a common connection work for suede, so there is no special attention required. However, the two wear-resistant layers 2 are symmetrically distributed on the base layer 1, that is, there are contact points between the upper end of the wear-resistant layer 2 and the upper end of the base layer 1, and between the lower end of the wear-resistant layer 2 and the lower end of the base layer 1. In order to reduce the possibility of the wear-resistant layer 2 and the base layer 1 separating under the action of external force, it is necessary to perform bonding between the wear-resistant layer 2 and the base layer 1. After sewing and bonding, upper limit band 13 is fitted at the upper connection between the upper wear-resistant layer 2 and the base layer 1, and upper limit band 24 is fitted at the lower connection between the lower wear-resistant layer 2 and the base layer 1. This further ensures the connection between the wear-resistant layer 2 and the base layer 1. The upper limit band 13 and the upper limit band 24 can also be made of elastic soft rubber to control the loop area of ​​the upper limit band 13 and the loop area of ​​the upper limit band 24, so as to fit the connection between the wear-resistant layer 2 and the base layer 1.

[0048] To facilitate the application of suede in the manufacture of abrasion-resistant gloves, the base layer 1 can be made of high-density nylon, while the abrasion-resistant layer 2 can be made of an organosilicon film. This not only ensures a smooth and convenient connection between the base layer 1 and the abrasion-resistant layer 2, but also, after hydrophobic and lubricating treatment, results in a more compact structure, improved pressure and abrasion resistance, and enhanced glove stability and lifespan. The abrasion groove 4 further restricts the abrasion-resistant layer 2, enhancing the mutual restraint effect between the two layers under external force. This reduces the likelihood of the suede loosening due to external forces.
