The device is comprehensive in function, novel in design, helps with sleep quality, and has high use value.

[0004] Although the above-mentioned prior arts have produced good practical effects on the improvement direction of fabrics, since special fabrics are required to have many special functions, a simple stacking layer structure will not only increase the cost but also make the fabric itself too thick and difficult to process, and the pattern is not easy to handle. Summary of the invention

[0005] The purpose of the present invention is to provide an antibacterial and wear-resistant textile fabric and a preparation method thereof, so as to solve the problem that although the existing technology proposed in the above background technology has produced good practical effects on the improvement direction of the fabric, due to the large number of special functions required for special fabrics, the simple stacking layer structure will not only increase the cost but also cause the fabric itself to be too thick and difficult to process, and the pattern is difficult to handle.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an antibacterial and wear-resistant textile fabric, comprising an inner layer and a polyvinyl chloride outer layer constituting the fabric and the polyvinyl chloride fabric as a whole, and a core layer wrapped between the inner and outer layers, and the three layers are reinforced and connected by sutures, and the core layer is a double-layer composite structure, wherein the core layer also includes a reinforcement mechanism, which enhances the wear resistance of the fabric by stacking up and down, and the reinforcement mechanism is used to adjust the thickness of the core layer.

[0007] As a further feature, the core layer is a composite structure composed of upper and lower double-layer sheet structures, the edges of the composite structure are sealed, and the middle forms a hollow body formed by the upper and lower double-layer sheets and surrounding sealing lines.

[0008] As a further feature, the hollow body is provided as a single body, and the core layer sheet structures on the upper and lower sides of the hollow body are fixed on the outer layer and the inner layer of polyvinyl chloride respectively.

[0009] As a further feature, the hollow bodies are evenly distributed, wherein the hollow bodies are separated by sutures or adhesives, wherein the separations are also used to connect with the outer and inner layers of polyvinyl chloride.

[0010] As a further feature, the reinforcement mechanism comprises two upper and lower groups of metal parts with filamentary structures, the metal parts comprise a first metal strip and a second metal strip, wherein the vertical projections of the two groups of metal strips are staggered.

[0011] As a further feature, the metal part is made of a memory alloy material, which can deform or restore its pre-deformation state at room temperature or high temperature.

[0012] As a further feature, the first metal strip and the second metal strip are located on the top wall and the bottom wall inside or outside the core layer, respectively.

[0013] As a further feature, a through hole is provided on the surface of the polyvinyl chloride outer layer, and a through hole is provided below the corresponding position of the through hole, which vertically penetrates the core layer and is not connected to the hollow body.

[0014] As a further feature, the core layer is provided with air holes communicating with the hollow body, and the air holes are also consistent with the hemispherical bodies arranged in the inner layer and the polyvinyl chloride outer layer.

[0015] The beneficial effects of the present invention are: redesigning the functional layer structure inside the fabric, being able to achieve multiple effects through the reinforcement mechanism and the structural design of the core layer, taking into account the functional effects such as the wear resistance of the fabric while ensuring that the fabric itself is not too thick or has problems with the pattern being difficult to handle, as shown in the following content.

[0016] 1. The structural design of the core layer and the hollow body, in conjunction with the design of the reinforcement mechanism, can, on the one hand, utilize the reinforcement mechanism in the core layer to reinforce the overall structural strength of the fabric or cloth, and on the other hand, can utilize the reinforcement mechanism to improve the wear resistance of the cloth. At the same time, the thickness of the core layer can be adjusted through the reinforcement mechanism, so that the core layer has the function of improving the thermal insulation effect.

[0017] Furthermore, by designing the first metal strip and the second metal strip to be in the form of a memory alloy material, on the one hand, its high rebound effect can be utilized to increase the bending and wear resistance and impact resistance of the fabric itself; on the other hand, the change in the specific ambient temperature can be utilized to guide the deformation of the core layer to achieve different effects.

[0018] 2. The design of multiple groups of through-hole structures such as air holes can, on the one hand, reduce the overall weight of the fabric and reduce the burden of wearing. On the other hand, the hole design can make the holes become air flow channels when the metal strips are in the corresponding state, thereby increasing the breathability of the fabric.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 8 , the present invention provides the following technical solutions:

[0030] Embodiment 1: The content disclosed in this embodiment is mainly to solve the problems existing in the prior art. For details, please refer to Figure 1-Figure 2 The content shown in the figure includes an inner layer 2 and a polyvinyl chloride outer layer 1 constituting the fabric and the polyvinyl chloride fabric as a whole, and a core layer 3 wrapped between the inner and outer layers, and the three layers are reinforced and connected by a suture line 4. The core layer 3 is a double-layer composite structure, wherein the core layer 3 also includes a reinforcement mechanism, which is stacked up and down to enhance the wear resistance of the fabric, and the reinforcement mechanism is used to adjust the thickness of the core layer 3. The fabric itself includes an inner layer 2 and a polyvinyl chloride outer layer 1. The core layer 3 is used as an intermediate structure between the two layers. Although it will increase the thickness and weight of the overall finished fabric to a certain extent, it can enhance the overall structural strength of the fabric. At the same time, a reinforcement mechanism is also arranged on the core layer 3, wherein the reinforcement mechanism can be a metal strip or metal sheet or other material with good toughness for enhancing the overall structural strength of the fabric. At the same time, since the reinforcement mechanism should also have the function of guiding the thickness of the core layer 3, the reinforcement mechanism should also have good elasticity, such as a metal wire, etc., which can guide the core layer 3 to undergo a large deformation or deformation under specified circumstances manually or by other means and maintain it in a predetermined shape.

[0031] The solution disclosed in this embodiment further discloses the detailed composition of the core layer 3, and enables the core layer 3 to have corresponding buffering and deformation functions, as shown in the following example. Figure 3As shown, the core layer 3 is a composite structure composed of an upper and lower double-layer sheet structure, the edges of the composite structure are sealed, and a hollow body 5 formed by the upper and lower double-layer sheets and the surrounding sealing lines is formed in the middle. The hollow body 5 is set individually, and the core layer 3 sheet structures on the upper and lower sides of the hollow body 5 are respectively fixed on the polyvinyl chloride outer layer 1 and the inner layer 2. The hollow bodies 5 are evenly distributed, and the hollow bodies 5 are separated by sutures or adhesives, and the separations are also used to connect with the polyvinyl chloride outer layer 1 and the inner layer 2. The core layer 3 itself can be airtight or air-permeable. The space of the hollow body 5 formed between the core layers 3 can just become the insulation space of the fabric itself, and improve the insulation effect by increasing the heat radiation penetration path. The difference is that the hollow bodies 5 with different distribution forms can bring relatively different effects. When the hollow body 5 is a single hollow structure in a single piece of fabric, the reinforcement and wear resistance of the core layer 3 used to form the space are better. When the hollow body 5 is cut into multiple spaces in the core layer 3 by sewing or bonding, such as Figure 3 As shown, the overall bending and stretching properties of the fabric formed are better.

[0032] The solution disclosed in this embodiment aims to improve the applicability of the fabric in special environments, such as Figure 4 As shown, the reinforcement mechanism includes two groups of metal parts with filamentary structures, the metal parts include a first metal strip 6 and a second metal strip 7, wherein the vertical projections of the two groups of metal strips are staggered, the metal parts are memory alloy materials, which will deform or restore the pre-deformation state at room temperature or high temperature, the metal parts include the first metal strip 6 and the second metal strip 7 located on the inner wall of the core layer 3, in the initial state, that is, when the thickness of the core layer 3 is small, the upper and lower layers of the core layer 3 are close to each other and the metal strips will also fit correspondingly, at this time, the overlapping metal strips will make the metal parts as a whole form a structure similar to a metal surface, so it can play a better wear and cut resistance effect compared with traditional cotton or chemical fiber materials, and because the metal strip itself is a material of memory alloy, it can be set to a material that can be deformed accordingly at low temperature or high temperature, and the reciprocating deformation characteristics of the two-way memory alloy are utilized to restore the initial state when the fabric is at room temperature or in a normal state under special environment, so that the core layer 3 can expand under specific conditions to increase the thermal insulation effect or shrink, the first metal strip 6 and the second metal strip 7 are respectively located on the top wall and the bottom wall inside or outside the core layer 3.

[0033] Embodiment 2: The solution disclosed in this embodiment is to further simply but effectively expand the effects of the core layer 3 and the hollow body 5. Specifically, Figure 7 and Figure 8As shown, a through hole 8 is provided on the surface of the polyvinyl chloride outer layer 1, and a through hole 9 is provided below the corresponding position of the through hole 8, which is vertically penetrated and opened on the core layer 3 and is not connected with the hollow body 5. The two hole structures are consistent with the protrusion 10 provided in the inner layer 2 from top to bottom. The core layer 3 is also provided with an air hole 11 connected with the hollow body 5, and the air hole 11 is also consistent with the hemispherical body 12 provided in the inner layer 2 and the polyvinyl chloride outer layer 1. When the core layer 3 is actively deformed or passively bent, the active deformation refers to the core layer 3 being deformed at the first metal strip 6. The core layer 3 is deformed under the guidance of the second metal strip 7, and the core layer 3 can undergo corresponding external deformation according to the distribution state of the metal strips. Passive deformation refers to when the fabric is near the wearer's bendable or movable joints, the user's movements will cause the core layer 3 to deform. In this process, on the one hand, the air flow can pass through the through hole 8 into the fabric to increase the breathability of the fabric itself. On the other hand, the air flow conveying effect generated by the air holes 11 during the deformation of the core layer 3 can also enhance the breathability.
