Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabrics, and in particular to a vertical striped nonwoven fabric. Background Technology

[0002] Nonwoven fabric, as a type of nonwoven material, has many advantages such as simple manufacturing process, low cost, and good breathability, and has been widely used in many fields such as medical, hygiene, packaging, and decoration.

[0003] However, existing nonwoven fabric products have certain limitations in terms of structure and function. Ordinary nonwoven fabrics typically have a relatively flat surface and lack specific three-dimensional structures, which makes them less effective in certain applications, such as those requiring enhanced friction or directional liquid flow. For example, in medical and nursing products, designing the surface structure of nonwoven fabrics to guide the directional absorption of liquids can effectively improve the product's performance. Utility Model Content

[0004] Therefore, in view of the above problems, this utility model provides a vertical striped nonwoven fabric, which mainly solves the problem of poor performance caused by the structural deficiencies of nonwoven fabrics in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vertical striped nonwoven fabric includes a nonwoven substrate layer with a basis weight of 20 g / m² to 100 g / m². The surface of the substrate layer has several parallel and uniformly distributed vertical stripe structures, each with a width of 0.1 mm to 5 mm and a spacing of 0.5 mm to 10 mm between adjacent stripe structures. A composite structure is provided on the surface of the substrate layer between adjacent stripe structures. This composite structure includes several hot-pressing points arranged in rows, with the hot-pressing points of adjacent hot-pressing structures interleaved. The substrate layer comprises at least two types of nonwoven fibers with different diameters bonded together by thermal or chemical bonding. One type of nonwoven fiber has a diameter of 0.5 μm to 1.5 μm, and the other type has a diameter of 2.0 μm to 5.0 μm. The mass ratio of the two types of nonwoven fibers with different diameters in the substrate layer is 1:1 to 1:3.

[0007] Furthermore, the nonwoven fabric substrate layer is a single-layer structure or a multi-layer composite structure. When it is a multi-layer composite structure, at least one layer has a vertical stripe structure on its surface, and the layers are bonded together by adhesive, hot-melt or mechanical winding.

[0008] Furthermore, one surface of the nonwoven fabric substrate layer is provided with an antibacterial functional layer, the antibacterial functional layer including a coating layer coated with a silver ion antibacterial agent, wherein the silver ion antibacterial agent in the coating layer accounts for 0.5% to 3% of the mass of the antibacterial functional layer.

[0009] Furthermore, the thickness of the antibacterial functional layer is 5μm to 20μm.

[0010] Furthermore, the hot pressing point has a circular, elliptical, rectangular, trapezoidal, triangular, or semi-circular structure.

[0011] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: The vertical striped nonwoven fabric, with several parallel and evenly distributed vertical stripe structures on the surface of the nonwoven fabric substrate layer, can guide the directional flow of liquid. In medical and nursing products, it can achieve rapid absorption and directional guidance of liquid, avoid liquid diffusion, and improve the performance of the product. Meanwhile, the vertical stripe structure increases the friction of the nonwoven fabric surface, making it more effective in applications requiring anti-slip properties. Furthermore, the width of the vertical stripes ranges from 0.1mm to 5mm, and the spacing between adjacent stripes ranges from 0.5mm to 10mm. This reasonable size range can be adjusted according to different usage requirements, ensuring structural stability while meeting the requirements for liquid guidance and friction in various scenarios. The composite structure between adjacent vertical stripes includes several hot-pressing points arranged in rows with staggered hot-pressing points between adjacent structures. This enhances the strength and stability of the nonwoven fabric substrate layer, improving its durability. The staggered distribution of the hot-pressing points also helps improve the breathability and softness of the nonwoven fabric. Moreover, the nonwoven fabric substrate layer is composed of at least two types of nonwoven fibers with different diameters bonded together by thermal or chemical bonding, fully utilizing the advantages of different fiber diameters. Fine fibers improve the softness and fineness of the nonwoven fabric, while coarse fibers enhance its strength and stiffness, significantly improving the overall performance of the nonwoven fabric.

[0015] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0016] The embodiment of this utility model is as follows:

[0017] refer to Figure 1 , Figure 2 and Figure 3 As shown, a vertical striped nonwoven fabric includes a nonwoven substrate layer 1 with a basis weight of 20 g / m² to 100 g / m², preferably 55 g / m². The surface of the nonwoven substrate layer 1 has several parallel and uniformly distributed vertical stripe structures 2, formed by mechanical pressing, hot pressing, or ultrasonic pressing, preferably mechanical pressing. The width of each vertical stripe structure 2 is 0.1 mm to 5 mm, preferably 3 mm, and the spacing between adjacent vertical stripe structures 2 is 0.5 mm to 10 mm, preferably 8 mm. A composite structure is provided on the surface of the nonwoven substrate layer 1 between adjacent vertical stripe structures 2, the composite structure including several hot-pressing points 3 arranged in a row. The hot-pressing points 3 of two adjacent hot-pressing structures are staggered. The nonwoven fabric substrate layer 1 includes at least two types of nonwoven fabric fibers with different fiber diameters bonded together by thermal bonding or chemical bonding. Preferably, the two types of nonwoven fabric fibers with different fiber diameters are bonded together by thermal bonding, such that the two types of nonwoven fabric fibers with different fiber diameters are a first nonwoven fabric fiber 11 and a second nonwoven fabric fiber 12. The fiber diameter of the first nonwoven fabric fiber 11 is 0.5μm to 1.5μm, preferably 0.8μm, and the fiber diameter of the second nonwoven fabric fiber 12 is 2.0μm to 5.0μm, preferably 3μm. The mass ratio of the second nonwoven fabric fiber 12 to the first nonwoven fabric fiber 11 is 1:1 to 1:3, preferably 1:2.

[0018] This vertical striped nonwoven fabric features several parallel and evenly distributed vertical stripe structures 2 on the surface of the nonwoven fabric substrate layer 1. These structures guide the directional flow of liquid, enabling rapid absorption and directional guidance of liquids in medical and nursing products, preventing liquid diffusion and improving product performance. Simultaneously, the vertical stripe structures 2 increase the friction of the nonwoven fabric surface, making it more effective in applications requiring anti-slip properties. Furthermore, the width of the vertical stripe structures 2 ranges from 0.1mm to 5mm, and the spacing between adjacent vertical stripe structures 2 ranges from 0.5mm to 10mm. This reasonable dimensional range can be adjusted according to different usage requirements, ensuring structural stability while meeting the requirements for liquid guidance and friction in various scenarios. The composite structure between adjacent vertical stripe structures 2 includes several rows of adjacent... The staggered distribution of hot-pressing points 3 in the two hot-pressing structures enhances the surface strength and stability of the nonwoven fabric substrate layer 1, improving the durability of the nonwoven fabric. At the same time, the staggered distribution of hot-pressing points 3 helps to improve the breathability and softness of the nonwoven fabric. Furthermore, the nonwoven fabric substrate layer 1 is composed of at least two types of nonwoven fabric fibers with different diameters through thermal bonding or chemical bonding, which fully utilizes the advantages of fibers with different diameters. Fine fibers can improve the softness and fineness of the nonwoven fabric, while coarse fibers enhance the strength and stiffness of the nonwoven fabric, resulting in a significant improvement in the overall performance of the nonwoven fabric.

[0019] Furthermore, the nonwoven fabric substrate layer 1 is a single-layer structure or a multi-layer composite structure. When it is a multi-layer composite structure, at least one layer has a vertical stripe structure on its surface, and the layers are bonded together by adhesive, hot-melt or mechanical winding. The flexible structural design can be customized according to different application scenarios and performance requirements. For example, in situations where higher strength or special functions are required, a multi-layer composite structure can be used, and the optimal combination of performance can be achieved by reasonably setting the position of the vertical stripe structure.

[0020] Furthermore, one surface of the nonwoven fabric substrate layer 1 is provided with an antibacterial functional layer 4. The antibacterial functional layer 4 includes a coating layer coated with a silver ion antibacterial agent. The silver ion antibacterial agent in the coating layer accounts for 0.5% to 3% of the mass of the antibacterial functional layer, preferably 1.8%. The silver ion antibacterial agent has good antibacterial properties and can effectively inhibit the growth and reproduction of bacteria, reducing the risk of infection caused by bacterial growth during the use of nonwoven fabric, and improving the safety and hygiene of the product. It is particularly suitable for medical, hygiene and other fields with high hygiene requirements. The thickness of the antibacterial functional layer 4 is 5μm to 20μm, preferably 15μm. This thickness range ensures the antibacterial effect without significantly affecting the overall performance of the nonwoven fabric. An excessively thick antibacterial functional layer may increase costs and affect the softness of the nonwoven fabric, while an excessively thin layer may not achieve the ideal antibacterial effect. This thickness range achieves a balance between antibacterial performance and product performance.

[0021] Meanwhile, the hot pressing point 3 has a circular, elliptical, rectangular, trapezoidal, triangular, or semi-circular structure, preferably an elliptical structure. The angle between the major axis of the hot pressing point 3 and the horizontal line is 45°. The pressing points are evenly distributed, which can enhance the strength of the nonwoven fabric in a specific direction.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.
