In order to block the sunlight, the aperture of the air holes cannot be too large, and the aperture of the air holes needs to be minimized as much as possible. The air holes with small apertures block the air, which in turn has a negative effect on the air permeability of the air holes, reduces the air permeability of the fabric, and reduces the air permeability of the air holes. Therefore, it is necessary to reduce the degree of air permeability blocked by the aperture problem of the air holes;
[0004] Therefore, it is necessary to improve existing knitted fabrics. Utility Model Content

[0032] It should be noted that the directional nouns "inside" and "outside" in the present invention are described relative to the use status of the fabric. Specifically, the fabric in this embodiment on the side close to the user is described as the "inside", and the fabric in this embodiment on the side away from the user is described as the "outside". The above descriptions are for the convenience of description and cannot be understood as the specific structure of the present invention.
[0033] The following will be combined with the attached Figure 1-10 The utility model is further described with examples.
[0034] It should be noted that, in order to clearly express the structure of each part of the utility model, the microstructure of the wiring logic of the wire is omitted in the figures disclosed in the utility model, and only the macrostructure of the fabric after molding is shown.
[0035] This embodiment discloses a breathable knitted fabric.
[0036] In order to block the sunlight, the aperture of the ventilation holes on the fabric cannot be too large. The aperture of the ventilation holes needs to be minimized as much as possible. However, the ventilation holes with small apertures block the air, which in turn has a negative effect on the breathability of the fabric and reduces the breathability of the ventilation holes. To solve the above problem, refer to Figure 1-10 A breathable knitted fabric comprises a surface layer 1, a middle layer 2 and a bottom layer 3. The surface layer 1 is sewn to the outer side of the middle layer 2, the surface layer 1 is the fabric layer far away from the user, the bottom layer 3 is sewn to the inner side of the middle layer 2, the bottom layer 3 is the fabric layer that is most close to the user, the surface layer 1 and the middle layer 2 are connected by sewing technology, the middle layer 2 and the bottom layer 3 are connected by sewing technology, the surface layer 1 is sewn with outer air holes 4, the middle layer 2 is sewn with middle air holes 5, and the bottom layer 3 is sewn with bottom air holes 6, the hole cross-sectional areas of the outer air holes 4, the hole cross-sectional areas of the middle air holes 5, and the hole cross-sectional areas of the bottom air holes 6 decrease in sequence, the outer air holes 4, the middle air holes 5, and the bottom air holes 6 are all formed by sewing technology, when the user uses it, the air passes through the outer air holes 4 of the surface layer 1 and then enters the middle air holes 5 of the middle layer 2 , and finally comes into contact with the user's skin through the bottom ventilation holes 6 of the bottom layer 3. The effect is that the apertures of the holes through which the air passes are from large to small. The outer ventilation holes 4 with the largest aperture reduce the fabric's barrier to air. The fabrics of the middle layer 2 and the bottom layer 3 themselves have gaps formed by sewing, hereinafter referred to as middle gaps and bottom gaps. Most of the air entering the outer ventilation holes 4 will pass through the middle ventilation holes 5, and a small part will pass through the middle gaps. Finally, most of the air passes through the bottom ventilation holes 6, and a small part passes through the bottom gaps, and then the air comes into contact with the user. The width of the air channel from the outside to the inside gradually decreases, which optimizes the gas flow rate and improves the ventilation effect. While improving the shading effect of the fabric, it reduces the fabric's barrier to air, improves the breathability of the fabric, and improves the user's sense of freshness when using it.
[0037] Due to its breathable properties, breathable knitted fabrics can provide users with a refreshing and ventilated wearing feeling. However, when users wear the fabrics, their skin will inevitably sweat, which will affect their wearing feeling. Therefore, in order to solve the above problem, the bottom layer 3 of this embodiment is sewn from bamboo charcoal fiber threads. The raw materials of the bamboo charcoal fiber threads include bamboo charcoal fibers, and bamboo charcoal fibers have excellent moisture absorption, perspiration and antibacterial properties. When the user's skin sweats, it can effectively absorb sweat on the body surface and transfer the sweat on the body surface to the middle layer 2 and the surface layer 1, and then discharge the sweat. At the same time, bamboo charcoal fibers can control bacterial growth and reduce odor generation, which helps users inhibit bacterial invasion, so that bamboo charcoal fibers can provide users with a comfortable wearing experience.
[0038] When users wear clothes, whether in daily life or in daily exercise, they require the clothes to have a certain wear resistance, otherwise the clothes will be easily damaged by friction. Therefore, the knitted fabric of this embodiment is required to have a certain wear resistance. In order to solve the above problem, the surface layer 1 of this embodiment is sewn from polyester wire. The raw materials of the polyester wire include polyester. Polyester has good wear resistance and durability, which makes the knitted fabric not easy to wear or break. At the same time, polyester has good wrinkle resistance, which can reduce the possibility of wrinkles on the knitted fabric during daily use of users and improve the aesthetics of the knitted fabric.
[0039] When the knitted fabric of the present embodiment is used to make clothes for summer use, the body's heat dissipation demand increases due to the high weather temperature in summer. If the knitted fabric can improve its heat dissipation performance, the user's comfort will also be improved. To achieve the above purpose, the middle layer 2 of the present embodiment is sewn from ice silk wire, and the raw materials of the ice silk wire include ice silk. Ice silk has good heat dissipation performance and moisture absorption and perspiration characteristics, can quickly take away the heat from the user's skin surface and quickly absorb sweat. Therefore, ice silk makes the knitted fabric give the user a cool and refreshing feeling when worn in summer, helps to keep the user's body dry and comfortable, and improves the user's comfort level.
[0040] After the bottom layer 3 absorbs sweat, as the sweat flows in the bottom layer 3, the sweat will be absorbed by the middle layer 2. In order to enhance the flow efficiency of sweat between the bottom layer 3 and the middle layer 2, the present embodiment also includes a winding wire 7 for connecting the bottom layer 3 and the middle layer 2. The winding wire 7 is wound between the bottom layer 3 and the middle layer 2 through the bottom air vents 6 and the middle air vents 5. Through the above arrangement, the user's sweat can be absorbed not only through the bottom layer 3, but also through the winding wire 7, thereby realizing a variety of sweat absorption methods, thereby improving the sweat absorption rate and improving the user's wearing comfort.
[0041] As before, the winding thread 7 not only serves to connect the bottom layer 3 and the middle layer 2, but also serves to conduct the user's sweat to the middle layer 2, thereby reducing the amount of sweat in the bottom layer 3. In order to further improve the sweat conductivity of the winding thread 7, the winding thread 7 of this embodiment is sewn with cotton thread. The raw material of the cotton thread is cotton. Cotton has good moisture absorption properties and can quickly absorb body sweat, and then conduct the sweat from the user's skin through the bottom layer 3 to the middle layer 2, and then to the surface layer 1, thereby improving the absorption rate of the user's skin sweat. At the same time, the cotton fiber is soft to the touch, which can improve the user's wearing comfort.
[0042] In order to further improve the conductivity of sweat between the middle layer 2 and the surface layer 1, so that it can be absorbed by the fabric, thereby reducing the possibility of sweat blocking the breathability of the fabric, in order to solve the above problem, the middle layer 2 and the surface layer 1 of this embodiment are sewn together, and the sewing line between the middle layer 2 and the surface layer 1 is cotton thread. Through the above arrangement, the conductivity of sweat between the middle layer 2 and the surface layer 1 is improved, thereby improving the sweat conductivity of the fabric, thereby reducing the possibility of sweat blocking the breathability of the fabric and affecting the breathability of the fabric.
[0043] Since the surface layer 1 is usually stretched along with the user's movements when the user uses the knitted fabric, it is necessary to improve the elasticity of the polyester wire used in the fabric in the structure of the surface layer 1 itself. To solve the above problem, the cross-section of the outer air vents 4 of this embodiment is rhombus-shaped. The rhombus-shaped outer air vents 4 are more flexible due to the variability brought by their shape. The fabric can be stretched along the diagonal of the rhombus, thereby improving the elastic effect of the fabric.
[0044] Since the middle layer 2 absorbs sweat from the bottom layer 3 during use of the fabric, it also needs to play a breathable role. In order to further enhance the above-mentioned role of the middle layer 2, the cross-section of the middle air holes 5 in this embodiment is square, and the opening area of the outer air holes 4 is larger than the opening area of the middle air holes 5. The square middle air holes 5 form a regular grid structure on the surface of the middle layer 2, so that air can flow through the fabric more evenly, thereby improving the overall breathability uniformity. The square middle air holes 5 can reduce the tightness of the fabric, making the fabric softer and more comfortable. The presence of the middle air holes 5 makes the fabric more elastic and more suitable for the body curve of the user.
[0045] Since the bottom layer 3 not only has the functions of ventilation and sweat absorption, but also helps the user to block light and avoid light, and the middle layer 2 has the middle air holes 5 that play a greater ventilation role. The middle air holes 5 have a larger aperture to increase the ventilation effect, which in turn affects the light-blocking property of the fabric. Therefore, the light-blocking property of the fabric needs to be improved through the bottom layer 3. To solve the above problem, the cross-section of the bottom air holes 6 of this embodiment is circular, and the bottom air holes 6 are inscribed in the middle air holes 5. Through the above arrangement, the bottom air holes 6 are smaller than the middle air holes 5, thereby improving the light-blocking property of the bottom layer 3 and the light-blocking property of the fabric.
[0046] It should be noted that the air blocking effect of the fabric produces: the blocked air that cannot come into contact with the user is originally blocked in the outermost layer of the fabric. Through the arrangement of the present embodiment, although part of the blocked air will be blocked by the fabric in the end, a part of it is blocked in the bottom layer 3 of the fabric, and this position is closer to the user than in the outermost layer of the fabric, i.e., the surface layer 1, so the cool feeling of the air perceived by the user will be more obvious. That is, the effect of the present embodiment includes improving the user's perception of the cool feeling of the blocked air by reducing the distance between the blocked position of the blocked air and the user's skin, thereby improving the user's wearing feel similar to the perception of the breathability of the fabric.
[0047] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
