Description

Technical Field

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

[0002] The technical problems existing in traditional textiles are poor bonding fastness and easy delamination, which affect subsequent processing such as cutting and dyeing, and are only suitable for low-strength market demands. In addition, the penetration of adhesives will increase the stiffness of the fabric and decrease the skin-friendly property, making it unfavorable for use.

[0003] To solve the above technical problems, fiber modification technology is generally adopted now. This is because fiber modification technology can improve hydrophilicity and softness, and can also improve the heat preservation performance.

[0004] When the existing textile fabrics are in use, the following technical problems still exist, such as:

[0005] 1. When the existing textile fabrics are manufactured, water-based glue is generally used for bonding. Using glue for bonding will affect its air permeability. This is because after multi-layer fabrics are bonded, the originally breathable fabric will have its pores penetrated by the glue, resulting in a decrease in air permeability.

[0006] 2. When the existing textile fabrics are in use, due to the use of glue for bonding, their air permeability decreases, and thus the air exchange inside and outside the fabric cannot be improved, which is not conducive to heat dissipation and is thus not conducive to the use of athletes.

[0007] Therefore, a modified composite textile fabric and a preparation method thereof are needed to solve the above problems. Summary of the Invention

[0008] The purpose of the present invention is to provide a modified composite textile fabric and a preparation method thereof, so as to solve the problems of the existing textile fabrics with decreased air permeability and inability to improve the air exchange inside and outside the fabric, which are not conducive to the use of athletes as mentioned in the above background art.

[0009] To achieve the above purpose, the present invention provides the following technical solutions:

[0010] A modified composite textile fabric includes a core layer, an outer layer and an inner layer respectively arranged on both sides of the core layer. Upper convex rings are evenly distributed on the upper surfaces of the core layer and the inner layer, and lower convex rings are evenly arranged on the lower surfaces of the core layer and the outer layer. Among them, the upper convex rings on the upper surface of the core layer correspond to the lower convex rings on the lower surface of the outer layer one by one, and the lower convex rings on the lower surface of the core layer and the upper convex rings on the upper surface of the inner layer correspond to each other one by one. Air cavities are evenly arranged inside the core layer, the outer layer and the inner layer, and air-permeable holes penetrating through the inner and outer sides of them are also arranged on the core layer, the outer layer and the inner layer.

[0011] Preferably, the upper convex rings on the upper surface of the core layer and the lower convex rings on the lower surface of the core layer are also arranged in one-to-one correspondence, and the air cavities provided on the core layer, the outer layer, and the inner layer are all arranged in one-to-one correspondence with the upper convex rings or the lower convex rings.

[0012] Preferably, the number of groups of the ventilation holes is set to be the same as the number of the upper convex rings, and each group of ventilation holes is evenly distributed in the corresponding upper convex ring or lower convex ring, and the ventilation holes also penetrate through the corresponding air cavity.

[0013] Preferably, the inner diameter of the upper convex ring is matched with the outer diameter of the lower convex ring for enabling the upper convex ring to be engaged with the corresponding lower convex ring.

[0014] Preferably, the air cavity is disc-shaped, which is convenient for the air cavity to deform and promotes the gas exchange between the two sides inside and outside the air cavity.

[0015] Preferably, both the upper and lower surfaces of the core layer are connected to the outer layer and the inner layer by water-based glue.

[0016] Preferably, hydrophobic layers are provided on the surfaces of the ventilation holes and the air cavities to prevent the water-based glue from blocking the ventilation holes and the air cavities.

[0017] Preferably, the area enclosed by all the upper convex rings provided on the core layer is not greater than 1 / 4 of the area of the upper surface of the core layer, which is used to ensure the stable connection between the core layer and the outer layer and the inner layer through the water-based glue.

[0018] A preparation method of a fabric, the preparation method comprising the following steps:

[0019] Step 1: Material preparation, the inner layer is made of a blend of modified modal cotton fiber and cotton fiber to improve antibacterial property, skin-friendly property and comfort, the outer layer is made of modified graphene to reduce the friction coefficient and improve wear resistance, and the core layer is made of antistatic composite fiber to improve stain resistance and antistatic property;

[0020] Step 2: Brush a layer of water-based glue on the upper and lower surfaces of the core layer, and respectively attach the outer layer and the inner layer to the upper and lower surfaces of the core layer to make the three composite;

[0021] Step 3: Move the outer layer and the inner layer so that the upper convex rings on the upper surface of the core layer are engaged with the lower convex rings on the lower surface of the outer layer, and the lower convex rings on the lower surface of the core layer are engaged with the upper convex rings on the upper surface of the inner layer;

[0022] Step 4: Shake the core layer, the outer layer and the inner layer after attachment to shake out the water-based glue remaining in the ventilation holes and the air cavities to prevent blocking the ventilation holes and the air cavities;

[0023] Step 5: Dry at a temperature of 60 - 80 °C;

[0024] Step 6: Use dense thin needles to pierce the composite fabric to prevent the fabric from being airtight after the water-based glue solidifies, so that positions other than the positions where the ventilation holes are provided can also have a certain degree of air permeability.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: The modified composite textile fabric can ensure stable composite connection of the core layer, outer layer and inner layer, and can avoid the problem of poor air permeability caused by the water-based glue. In addition, when the fabric shakes, it can improve the heat exchange efficiency of the gas inside and outside the fabric, thereby helping to cool down, making it convenient for the exerciser to use:

[0026] 1. By providing ventilation holes and hydrophobic layers on the ventilation holes, it is possible to prevent the core layer, outer layer and inner layer from sticking at the positions of the ventilation holes, and to avoid the solidification of the water-based glue in the ventilation holes, so as to prevent the water-based glue from blocking the ventilation holes. Furthermore, after ensuring the stable composite connection of the core layer, outer layer and inner layer through the ventilation holes, the air permeability will not be affected by the water-based glue;

[0027] 2. By providing air cavities and hydrophobic layers in the air cavities, it is possible to prevent the water-based glue from solidifying in the air cavities, thereby avoiding the blockage of the air cavities by the water-based glue. When the fabric is used, the air cavities will be stretched due to shaking, so that the efficiency of external gas entering the air cavities can be improved. Furthermore, it is convenient for heat exchange of the air on both sides of the fabric, which helps to quickly absorb the heat released by the body, making it convenient for the exerciser to use.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figures 1-8 , the present invention provides the following technical solutions:

[0039] Embodiment 1: To solve the problem that the air permeability of conventional textile fabrics is affected after being compounded with water-based glue, resulting in poor air permeability of existing textile fabrics, the following technical solutions are provided. Specifically, a modified composite textile fabric includes a core layer 1 and an outer layer 2 and an inner layer 3 respectively disposed on both sides thereof. Upper raised rings 5 are uniformly distributed on the upper surface of the core layer 1 and the upper surface of the inner layer 3, and lower raised rings 6 are uniformly disposed on the lower surface of the core layer 1 and the lower surface of the outer layer 2. Among them, the upper raised rings 5 on the upper surface of the core layer 1 correspond to the lower raised rings 6 on the lower surface of the outer layer 2 one by one, and the lower raised rings 6 on the lower surface of the core layer 1 and the upper raised rings 5 on the upper surface of the inner layer 3 correspond to each other one by one. Vent holes 4 penetrating through the inner and outer sides are also provided on the core layer 1, the outer layer 2 and the inner layer 3.

[0040] The upper raised rings 5 on the upper surface of the core layer 1 and the lower raised rings 6 on the lower surface of the core layer 1 also correspond to each other. The number of groups of vent holes 4 is set to be the same as the number of upper raised rings 5, and each group of vent holes 4 is evenly distributed in the corresponding upper raised ring 5 or lower raised ring 6. The inner diameter of the upper raised ring 5 matches the outer diameter of the lower raised ring 6 for enabling the upper raised ring 5 to be engaged with the corresponding lower raised ring 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. The area enclosed by all the upper raised rings 5 provided on the core layer 1 is not greater than 1 / 4 of the upper surface area of the core layer 1 to ensure the stable connection of the core layer 1 with the outer layer 2 and the inner layer 3 through water-based glue. During use, by engaging the upper raised rings 5 with the corresponding lower raised rings 6, the problem that the connection between the core layer 1 and the outer layer 2 and the inner layer 3 is insufficient due to the provision of the vent holes 4 is compensated. The vent holes 4 provided with a hydrophobic layer can prevent the water-based glue from solidifying at the position of the vent holes 4, thereby preventing the water-based glue from blocking the vent holes 4. When the fabric is in use, it can breathe through the vent holes 4, thereby ensuring the air permeability of the fabric and preventing the problem that the air permeability of the fabric becomes poor due to the water-based glue.

[0041] Example 2: To solve the problem that the previous wave compensation test bench insufficiently simulated the influence of waves on the working platform in reality, the following technical solution is provided. Specifically, air cavities 7 are uniformly arranged inside the core layer 1, the outer layer 2, and the inner layer 3, and the air cavities 7 are penetrated by ventilation holes 4.

[0042] The air cavities 7 arranged on the core layer 1, the outer layer 2, and the inner layer 3 are respectively arranged in one-to-one correspondence with the upper convex rings 5 or the lower convex rings 6. The air cavities 7 are disc-shaped, which is convenient for the air cavities 7 to deform and promotes the gas exchange on both sides of the air cavities 7. Hydrophobic layers are arranged on the surfaces of the ventilation holes 4 and the air cavities 7 to prevent water-based glue from blocking the ventilation holes 4 and the air cavities 7. During use, due to the arrangement of the air cavities 7, when the fabric shakes, the air cavities 7 will be pulled, thereby accelerating the gas on both sides of the air cavities 7 to enter the air cavities 7, improving the heat exchange efficiency of the gas on both sides. When the exerciser uses this fabric for exercise, it will cause the fabric to shake continuously, which helps to accelerate heat dissipation and thus helps the exerciser use this fabric.

[0043] A preparation method of a fabric, the preparation method includes the following steps:

[0044] Step 1: Material preparation. The inner layer 3 is made of a blend of modified modal cotton fiber and cotton fiber to improve antibacterial property, skin-friendly property and comfort. The outer layer 2 is made of modified graphene to reduce the friction coefficient and improve wear resistance. The core layer 1 is made of antistatic composite fiber to improve stain resistance and antistatic property.

[0045] Step 2: Brush a layer of water-based glue on the upper and lower surfaces of the core layer 1, and respectively bond the outer layer 2 and the inner layer 3 to the upper and lower surfaces of the core layer 1 to make the three composite.

[0046] Step 3: Move the outer layer 2 and the inner layer 3 so that the upper convex rings 5 on the upper surface of the core layer 1 are engaged with the lower convex rings 6 on the lower surface of the outer layer 2, and the lower convex rings 6 on the lower surface of the core layer 1 are engaged with the upper convex rings 5 on the upper surface of the inner layer 3.

[0047] Step 4: Shake the bonded core layer 1, outer layer 2, and inner layer 3 to shake out the water-based glue remaining in the ventilation holes 4 and the air cavities 7 to prevent blocking the ventilation holes 4 and the air cavities 7.

[0048] Step 5: Dry at a temperature of 60 - 80 °C.

[0049] Step 6: Use dense fine needles to pierce the composite fabric to prevent the fabric from being airtight after the water-based glue solidifies, so that positions other than the positions where the ventilation holes 4 are provided can also have a certain degree of air permeability.
