Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric technology, and in particular to a high-strength, wear-resistant polyester needle-punched nonwoven fabric. Background Technology

[0002] Polyester needle-punched nonwoven fabric is a common type of nonwoven fabric that plays an important role in many industries. It is made primarily from polyester fibers through a needle-punching process. First, short polyester fibers undergo opening and carding processes to form a fiber web. Then, a needle-punching machine with needles repeatedly punctures the fiber web. The barbs on the needles cause the fibers to entangle, gradually strengthening the initially loose fiber web and ultimately forming a nonwoven fabric with a certain strength and thickness.

[0003] In the existing technology, many nonwoven fabrics have low strength, are easily torn, have limited application range, and lower the application requirements. In addition, the wear resistance of nonwoven fabrics after use is poor, resulting in a short product life. Therefore, it is necessary to design a high-strength wear-resistant polyester needle-punched nonwoven fabric to solve the above problems.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through the specific circumstances.

[0028] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] See Figure 1 , Figure 2 and Figure 3 This utility model provides a high-strength, wear-resistant polyester needle-punched nonwoven fabric, comprising:

[0030] The polyester needle-punched nonwoven fabric substrate 1 has an upper reinforcing layer 2 and a lower reinforcing layer 3 at its top and bottom, respectively. It should be noted that the polyester needle-punched nonwoven fabric substrate 1 is a nonwoven base layer made of polyester fiber as raw material through a needle-punching process. Polyester has the characteristics of high strength, good elasticity, wear resistance, and corrosion resistance, which makes the nonwoven fabric have good durability. The needle-punching process uses barbed needles to repeatedly puncture the fiber web, causing the fibers to entangle with each other, thereby combining the originally loose fibers into a sheet-like structure with a certain strength and thickness.

[0031] An intermediate layer 4 is provided on the upper reinforcing layer 2, an upper reinforcing layer 6 is provided on the intermediate layer 4, a flame-retardant layer 8 is provided on the upper reinforcing layer 6, and a wear-resistant layer 10 is provided on the flame-retardant layer 8.

[0032] A second intermediate layer 5 is provided on the lower reinforcing layer 3, a second lower reinforcing layer 7 is provided on the second intermediate layer 5, a second flame-retardant layer 9 is provided on the second lower reinforcing layer 7, and a second wear-resistant layer 11 is provided on the second flame-retardant layer 9.

[0033] Specifically, reinforcing ribs 12 are connected between the upper reinforcing layer 1 (2) and the upper reinforcing layer 2 (6), and reinforcing ribs 12 are connected between the lower reinforcing layer 1 (3) and the lower reinforcing layer 2 (7). Reinforcing filaments 13 are fixedly installed on the reinforcing ribs 12. The reinforcing ribs 12 are made of polyester fiber, and the reinforcing filaments 13 are made of aramid fiber. It should be noted that the polyester fiber reinforcing ribs and the aramid fiber reinforcing filaments work together. The reinforcing ribs 12 provide basic support, while the reinforcing filaments 13, with their high strength and high temperature resistance, further enhance the structural stability, effectively improve the tensile strength of the nonwoven fabric, and prevent it from being torn.

[0034] Specifically, reinforcing ribs 12 and reinforcing wires 13 are both located inside intermediate layer 4, and reinforcing ribs 12 and reinforcing wires 13 are both located inside intermediate layer 5. Intermediate layer 4 and intermediate layer 5 are both made of polyurethane. It should be noted that the good elasticity and flexibility of polyurethane allow intermediate layer 4 and intermediate layer 5 to withstand external compression and stretching and quickly return to their original shape, improving the comfort of using non-woven fabric. In addition, its abrasion resistance, chemical resistance and anti-aging properties help to extend the service life of the product.

[0035] Specifically, the upper reinforcing layer 12 and the lower reinforcing layer 13 are both made of glass fiber, while the upper reinforcing layer 26 and the lower reinforcing layer 27 are both made of basalt fiber. It should be noted that basalt fiber has high strength, high modulus, high temperature resistance, and chemical corrosion resistance, which further enhances the mechanical properties of the nonwoven fabric. It can maintain structural stability in harsh environments and enhance the overall durability and adaptability of the nonwoven fabric.

[0036] Specifically, flame-retardant layer 8 and flame-retardant layer 9 are both made of flame-retardant polypropylene fiber, while wear-resistant layer 10 and wear-resistant layer 11 are both made of nylon fabric. It should be noted that flame-retardant polypropylene fiber has flame-retardant properties and can effectively prevent the spread of fire when exposed to open flames or high temperatures, reducing the risk of non-woven fabric combustion. Nylon fabric has excellent wear resistance and can effectively resist frictional wear, reduce material damage caused by friction, and extend the service life of non-woven fabric in wear-prone environments.

[0037] Working principle:

[0038] The polyester needle-punched nonwoven fabric matrix 1 serves as the base layer. It is made of polyester fibers with high strength, good elasticity, wear resistance, and corrosion resistance through a needle-punching process, giving the nonwoven fabric a certain initial strength and thickness. The upper reinforcing layer 2 and the lower reinforcing layer 3 (made of glass fiber), as well as the upper reinforcing layer 6 and the lower reinforcing layer 7 (made of basalt fiber), further enhance the strength and rigidity of the nonwoven fabric from the upper and lower sides, respectively. The high strength and high modulus characteristics of glass fiber and basalt fiber enable the nonwoven fabric to disperse and withstand stress when subjected to external forces, making it less prone to deformation or damage, thus providing a solid foundation support for the entire structure.

[0039] The reinforcing ribs 12 (made of polyester fiber) and the reinforcing filaments 13 (made of aramid fiber) are located inside the intermediate layer 4 and the intermediate layer 5, forming a reinforced network structure. The reinforcing ribs 12 provide a basic support framework, while the reinforcing filaments 13, with their high strength and high temperature resistance, further enhance the stability of this network structure. When the nonwoven fabric is subjected to tensile force, the reinforcing ribs 12 and the reinforcing filaments 13 can effectively disperse the tensile force and prevent the nonwoven fabric from being torn, thereby improving the tensile strength of the nonwoven fabric.

[0040] Intermediate layer 4 and intermediate layer 5 are made of polyurethane, which has good elasticity and flexibility. When the nonwoven fabric is subjected to external pressure or stretching, the polyurethane intermediate layer can deform, absorb and buffer the external force, reduce the direct impact on other layers, and can quickly return to its original shape after the external force is removed, ensuring the shape stability and comfort of the nonwoven fabric. At the same time, the wear resistance, chemical resistance and anti-aging properties of polyurethane also help to extend the service life of the nonwoven fabric.

[0041] Flame-retardant layer 8 and flame-retardant layer 9 are made of flame-retardant polypropylene fibers. When exposed to open flames or high temperatures, the flame-retardant polypropylene fibers can play a flame-retardant role. Wear-resistant layer 10 and wear-resistant layer 11 are made of nylon fabric. Nylon has excellent wear resistance. When the non-woven fabric rubs against external objects during use, the nylon wear-resistant layer can directly bear the friction, reducing the wear on other internal layers. Its surface structure and material properties enable it to effectively resist friction loss, thereby extending the service life of the non-woven fabric in wear-prone environments and protecting the internal structure from damage.

[0042] The above provides a detailed description of a high-strength, wear-resistant polyester needle-punched nonwoven fabric provided by this utility model. Specific embodiments have been used to illustrate the principles and implementation methods of this utility model. The descriptions of these embodiments are merely for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
