Description

Technical Field

[0001] The invention relates to the technical field of composite textile fabrics, in particular to a modified composite textile fabric and a preparation method thereof. Background Art

[0002] The technical problems of traditional textiles are poor bonding fastness and easy delamination, which affects subsequent cutting, dyeing and other processing, and is only suitable for low-strength market demand. In addition, adhesive penetration will increase the stiffness of the fabric and reduce skin affinity, making it unfavorable for use; In order to solve the above technical problems, fiber modification technology is generally used now, because fiber modification technology can improve hydrophilicity and softness, and also improve thermal insulation performance; The existing textile fabrics still have the following technical problems when used, such as: 1. Existing textile fabrics are generally bonded with water-based glue during manufacturing. Bonding with glue will affect its air permeability. This is because after bonding multiple layers of fabrics, the pores of the originally breathable fabrics will be penetrated by the glue due to the bonding of the glue, resulting in a decrease in air permeability. 2. When using existing textile fabrics, due to the use of glue for bonding, their air permeability decreases, and thus the air exchange between the inside and outside of the fabric cannot be improved, which is not conducive to heat dissipation and is not conducive to use by athletes; Therefore, a modified composite textile fabric and a preparation method thereof are needed to solve the above problems. Summary of the invention

[0003] The purpose of the present invention is to provide a modified composite textile fabric and a preparation method thereof, so as to solve the problem mentioned in the above background technology that the air permeability of the existing textile fabric decreases and the air exchange inside and outside the fabric cannot be improved, so that it is not conducive to use by athletes.

[0004] To achieve the above object, the present invention provides the following technical solutions: A modified composite textile fabric comprises a core layer and an outer layer and an inner layer respectively arranged on both sides thereof, wherein the upper surface of the core layer and the upper surface of the inner layer are evenly distributed with upper raised circles, and the lower surface of the core layer and the lower surface of the outer layer are evenly arranged with lower raised circles, wherein the upper raised circles on the upper surface of the core layer correspond one-to-one with the lower raised circles on the lower surface of the outer layer, and the lower raised circles on the lower surface of the core layer correspond one-to-one with the upper raised circles on the upper surface of the inner layer, and the core layer, the outer layer and the inner layer are evenly arranged with air cavities inside, and the core layer, the outer layer and the inner layer are also provided with ventilation holes running through the inner and outer sides thereof.

[0005] Preferably, the upper raised circles on the upper surface of the core layer and the lower raised circles on the lower surface of the core layer are also arranged in one-to-one correspondence, and the air cavities arranged on the core layer, outer layer and inner layer are all arranged in one-to-one correspondence with the upper raised circles or the lower raised circles.

[0006] Preferably, the number of groups of the air holes is set to be the same as the number of the upper raised circles, and each group of air holes is evenly distributed in the corresponding upper raised circle or lower raised circle, and the air holes are also set through the corresponding air cavity.

[0007] Preferably, the inner diameter of the upper raised circle matches the outer diameter of the lower raised circle, so that the upper raised circle can be engaged with the corresponding lower raised circle.

[0008] Preferably, the air cavity is disc-shaped, which facilitates deformation of the air cavity and promotes the exchange of gas inside and outside the air cavity.

[0009] Preferably, the upper and lower surfaces of the core layer are connected to the outer layer and the inner layer by using water-based glue.

[0010] Preferably, the surfaces of the air holes and the air cavities are provided with a hydrophobic layer to prevent the air holes and the air cavities from being blocked by the water-based glue.

[0011] Preferably, the area enclosed by all upper protrusions provided on the core layer is no more than 1 / 4 of the upper surface area of ​​the core layer, so as to ensure that the core layer is stably connected to the outer layer and the inner layer through the water-based adhesive.

[0012] A method for preparing a fabric, the method comprising the following steps: Step 1: Material preparation: the inner layer is made of modified modal cotton fiber and cotton fiber blended to improve antibacterial properties, skin affinity and comfort; the outer layer is made of modified graphene to reduce the friction coefficient and improve wear resistance; the core layer is made of antistatic composite fiber to improve stain resistance and antistatic properties; Step 2: Apply a layer of water-based glue on the upper and lower surfaces of the core layer, and attach the outer layer and the inner layer to the upper and lower surfaces of the core layer respectively to make the three composite; Step 3: Move the outer layer and the inner layer so that the upper raised circle on the upper surface of the core layer is engaged with the lower raised circle on the lower surface of the outer layer, and the lower raised circle on the lower surface of the core layer is engaged with the upper raised circle on the upper surface of the inner layer; Step 4: Shake the laminated core layer, outer layer and inner layer to remove the water-based glue remaining in the vents and air cavities to prevent the vents and air cavities from being blocked; Step 5: Dry at 60-80℃; Step 6: Use dense fine needles to poke the composite fabric to prevent the fabric from becoming airtight after the water-based glue solidifies, so that the fabric can have a certain degree of air permeability except for the locations where the air holes are set.

[0013] Compared with the prior art, the invention has the following beneficial effects: the modified composite textile fabric can ensure stable composite connection between the core layer, the outer layer and the inner layer, and can avoid the problem of poor air permeability caused by water-based glue. In addition, when the fabric is shaken, the heat exchange efficiency of the gas inside and outside the fabric can be improved, thereby helping to reduce the temperature, so that it is convenient for athletes to use: 1. By setting air holes and a hydrophobic layer on the air holes, the core layer, outer layer and inner layer can be prevented from sticking at the position of the air holes, and the water-based glue can be prevented from solidifying in the air holes, so as to prevent the water-based glue from clogging the air holes. Then, the water-based glue can pass through the air holes, ensuring that the core layer, outer layer and inner layer are stably compositely connected, and the air permeability will not be affected by the water-based glue; 2. By setting an air cavity and a hydrophobic layer in the air cavity, the water-based glue can be prevented from solidifying in the air cavity, thereby avoiding the water-based glue from clogging the air cavity. When the fabric is used, the air cavity will be stretched due to shaking, thereby improving the efficiency of external gas entering the air cavity, and then facilitating heat exchange between the air on both sides of the fabric, which helps to quickly absorb the heat released by the body, making it easier for athletes to use.

[0016] 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.

[0017] See also Figure 1-Figure 8 , the present invention provides the following technical solutions: Embodiment 1: In order to solve the problem that the air permeability of textile fabrics is affected after being compounded with water-based adhesive, so that the existing textile fabrics have poor air permeability, the following technical solution is provided, specifically, a modified composite textile fabric, including a core layer 1 and an outer layer 2 and an inner layer 3 respectively arranged on both sides thereof, the upper surface of the core layer 1 and the upper surface of the inner layer 3 are evenly distributed with upper raised circles 5, and the lower surface of the core layer 1 and the lower surface of the outer layer 2 are evenly provided with lower raised circles 6, wherein the upper raised circles 5 on the upper surface of the core layer 1 correspond one-to-one with the lower raised circles 6 on the lower surface of the outer layer 2, and the lower raised circles 6 on the lower surface of the core layer 1 correspond one-to-one with the upper raised circles 5 on the upper surface of the inner layer 3, and the core layer 1, the outer layer 2 and the inner layer 3 are also provided with air holes 4 running through the inner and outer sides thereof.

[0018] The upper raised circle 5 on the upper surface of the core layer 1 and the lower raised circle 6 on the lower surface of the core layer 1 are also arranged one by one, the number of groups of air holes 4 is set to be the same as the number of the upper raised circle 5, and each group of air holes 4 is evenly distributed in the corresponding upper raised circle 5 or the lower raised circle 6, the inner diameter of the upper raised circle 5 is consistent with the outer diameter of the lower raised circle 6, so that the upper raised circle 5 can be engaged with the corresponding lower raised circle 6, the upper and lower surfaces of the core layer 1 are connected to the outer layer 2 and the inner layer 3 by water-based glue, and the area enclosed by all the upper raised circles 5 arranged on the core layer 1 is not larger than the area of ​​the upper surface of the core layer 1 1 / 4, used to ensure that the core layer 1 is stably connected to the outer layer 2 and the inner layer 3 through the water-based glue. When in use, the upper raised circle 5 and the corresponding lower raised circle 6 are engaged to make up for the problem of insufficient connection between the core layer 1 and the outer layer 2 and the inner layer 3 caused by the provision of the air hole 4. The air hole 4 provided with a hydrophobic layer can prevent the water-based glue from solidifying at the position of the air hole 4, thereby preventing the water-based glue from clogging the air hole 4. The fabric can be ventilated through the air hole 4 when in use, thereby ensuring the air permeability of the fabric and preventing the problem of poor air permeability of the fabric due to the water-based glue.

[0019] Embodiment 2: In order to solve the problem that the previous wave compensation test bench does not simulate the influence of waves on the working platform in reality sufficiently, the following technical solution is provided. Specifically, air cavities 7 are evenly arranged inside the core layer 1, the outer layer 2 and the inner layer 3, and the air cavities 7 are penetrated by air holes 4.

[0020] The air cavities 7 arranged on the core layer 1, the outer layer 2 and the inner layer 3 are arranged one by one corresponding to the upper raised circle 5 or the lower raised circle 6. The air cavity 7 is disc-shaped, which is convenient for the deformation of the air cavity 7 and promotes the exchange of gas on both sides of the air cavity 7. The surfaces of the air holes 4 and the air cavities 7 are provided with a hydrophobic layer to prevent the water-based glue from blocking the air holes 4 and the air cavities 7. When in use, due to the provision of the air cavity 7, when the fabric shakes, the air cavity 7 will be pulled, thereby accelerating the gas on both sides of the air cavity 7 to enter the air cavity 7, thereby improving the heat exchange efficiency of the gas on both sides. When athletes use the fabric for exercise, the fabric will cause the fabric to shake continuously, which will help to speed up the heat dissipation, thereby helping athletes to use the fabric.
