Abstract
Description
Technical Field
[0001] This utility model relates to the field of polyester webbing technology, specifically to a wear-resistant elastic polyester webbing. Background Technology
[0002] Abrasion-resistant elastic polyester webbing, as a textile accessory that combines elasticity and abrasion resistance, is widely used in clothing, bags, sports equipment, and industrial binding. During use, it frequently endures tensile deformation and external friction; therefore, the durability of elasticity and the abrasion resistance of the surface are core performance indicators affecting the webbing's user experience and service life, and are also key areas of focus in the design and production of this type of product.
[0003] In existing technologies, to impart elasticity to webbing, elastic threads are often only placed in the core layer without designing a reverse support and constraint structure for these threads. With this design, the elastic threads are prone to loosening or displacement after repeated stretching and deformation, leading to a gradual decrease in the webbing's elastic recovery ability and insufficient overall structural stability of the core layer. Furthermore, the connection between the core layer and the outer layer often employs a dense weaving method. This method generates strong mutual tensile forces between the core and outer layers during webbing deformation, limiting the elastic extension range of the webbing and easily causing loosening or even breakage at the interlayer connections. In addition, the outer layer of the webbing often uses polyester yarn with a conventional denier, which has weak abrasion resistance. After long-term use, the outer layer is prone to wear, pilling, and even damage, exposing the internal core layer and elastic components. This leads to frictional damage to the internal structure, ultimately shortening the overall service life of the webbing. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a wear-resistant elastic polyester webbing to solve the problem mentioned in the background art, where the internal structure is damaged by friction, ultimately shortening the overall service life of the webbing.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant elastic polyester webbing, comprising:
[0006] Core layer, the surface of which is covered with a surface layer;
[0007] Elastic polyester multifilament is disposed on the surface of the core layer. The elastic polyester multifilament is wound around the surface of the core layer. Polyester support yarn is wound around the surface of the elastic polyester multifilament. The winding direction of the polyester support yarn is opposite to the winding direction of the elastic polyester multifilament.
[0008] Connecting threads are provided on the inner wall of the surface layer. The connecting threads are spaced apart and distributed in a Z-shape. The core layer and the surface layer are woven together by the spaced connecting threads. High denier polyester yarn is interwoven and fixed on the surface of the surface layer.
[0009] Preferably, the polyester support filament has a non-circular cross-section, and the ends of the polyester support filament are all in contact with the outer surface of the elastic polyester multifilament, which can enhance the connection stability between the two and prevent loosening or separation during use, thereby improving the overall structural strength of the webbing.
[0010] Preferably, a polyester auxiliary filament is provided between the elastic polyester multifilaments. The polyester auxiliary filament is spirally wound around the outside of two adjacent elastic polyester multifilaments, which can further enhance the bonding force between the elastic polyester multifilaments, so that the highly elastic polyester multifilaments can work together better when subjected to force, and enhance the tensile strength of the webbing.
[0011] Preferably, the elastic polyester multifilament has a multi-strand twisted structure, and the elastic polyester multifilament is arranged radially around the center of the core layer. The multi-strand twisted structure gives the elastic polyester multifilament better elasticity and toughness, while the radial arrangement can evenly distribute the force, so that the webbing can withstand a certain amount of tension in different directions, thus improving its durability.
[0012] Preferably, the outer surface of the high-denier polyester yarn is covered with an abrasion-resistant fiber layer, which is fixed to the surface of the high-denier polyester yarn by winding. The winding method can ensure that the abrasion-resistant fiber layer is tightly bonded to the high-denier polyester yarn, and the abrasion-resistant fiber layer can effectively resist external friction and wear, thus extending the service life of the webbing.
[0013] Preferably, the high-denier polyester yarn is formed by twisting multiple polyester monofilaments together, and the twist direction of the multiple polyester monofilaments is opposite to the winding direction of the wear-resistant fiber layer, which makes the bond between the high-denier polyester yarn and the wear-resistant fiber layer stronger. When subjected to external force, it can better maintain the integrity of the structure and is less prone to delamination or detachment.
[0014] Compared with the prior art, this utility model provides a wear-resistant elastic polyester webbing with the following advantages:
[0015] This abrasion-resistant elastic polyester webbing features added elastic polyester multifilaments that directly provide basic elasticity. The opposite-direction winding design of the polyester support yarn and the elastic polyester multifilaments creates a reverse constraint on the elastic polyester multifilaments, enhancing the overall structural stability and elastic recovery durability of the core layer. The connecting yarn reduces the mutual pulling constraint between the core layer and the surface layer during elastic deformation, ensuring the strong connection between the layers. The high-denier polyester yarn directly improves the abrasion resistance of the surface layer, reducing wear and tear during use, thereby protecting the internal core layer, elastic polyester multifilaments, and polyester support yarn from external friction damage. This gives the webbing both good elasticity and excellent abrasion resistance, extending the service life of the polyester webbing. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] This utility model provides a technical solution: a wear-resistant elastic polyester webbing. (Please refer to...) Figure 1 It includes a core layer 1, and the surface of the core layer 1 is covered with a surface layer 2;
[0022] Please see Figure 2 Elastic polyester multifilament 3 is disposed on the surface of core layer 1. Elastic polyester multifilament 3 is wound around the surface of core layer 1. Polyester support filament 4 is wound around the surface of elastic polyester multifilament 3. The winding direction of polyester support filament 4 is opposite to the winding direction of elastic polyester multifilament 3.
[0023] Please see Figure 3 Connecting wires 5 are set on the inner wall of the surface layer 2. The connecting wires 5 are spaced apart and distributed in a Z-shape. The core layer 1 and the surface layer 2 are woven together by the spaced connecting wires 5. High denier polyester yarn 6 is interwoven and fixed on the surface of the surface layer 2.
[0024] The elastic polyester multifilaments 3 wound around the surface of the core layer 1 directly provide basic elasticity to the webbing. Meanwhile, the polyester support yarns 4 are wound around its surface in the opposite direction to the elastic polyester multifilaments 3, providing a reverse constraint without affecting elasticity. This prevents the elastic polyester multifilaments 3 from loosening and shifting during stretching or shrinking, thereby enhancing the overall structural stability and elastic recovery durability of the core layer 1. The connecting yarns 5, spaced apart and arranged in a Z-shape on the inner wall of the outer layer 2, enable the weaving connection between the core layer 1 and the outer layer 2. The Z-shaped structure itself has a certain amount of stretch allowance, and the spaced arrangement reduces the core layer's... The mutual tension and constraint between the core layer 1 and the surface layer 2 during elastic deformation ensures the firmness of the interlayer connection and further maintains the overall elasticity of the webbing, while preventing the layers from separating. The high-denier polyester yarn 6 interwoven and fixed on the surface of the surface layer 2, with its high strength and abrasion resistance, can directly improve the abrasion resistance of the surface layer 2, reduce the wear and tear of the surface layer 2 during the use of the webbing, and thus protect the internal core layer 1, elastic polyester multifilament 3 and polyester support yarn 4 from external friction damage. Ultimately, the webbing has both good elasticity and excellent abrasion resistance, extending its service life.
[0025] Please see Figure 2 The cross-section of the polyester support yarn 4 is non-circular, and the ends of the polyester support yarn 4 are in contact with the outer surface of the elastic polyester multifilament 3, which can enhance the connection stability between the two and prevent loosening or separation during use, thereby improving the overall structural strength of the webbing.
[0026] Polyester auxiliary yarns are provided between the elastic polyester multifilaments 3. The polyester auxiliary yarns are spirally wound around the outside of two adjacent elastic polyester multifilaments 3, which can further enhance the bonding force between the elastic polyester multifilaments 3, so that the highly elastic polyester multifilaments 3 can work together better when subjected to force, and enhance the tensile strength of the webbing.
[0027] The elastic polyester multifilament 3 has a multi-strand twisted structure, and the elastic polyester multifilament 3 is arranged radially around the center of the core layer 1. The multi-strand twisted structure gives the elastic polyester multifilament 3 better elasticity and toughness, while the radial arrangement can evenly distribute the force, so that the webbing can withstand a certain amount of tension in different directions, thus improving its durability.
[0028] Please see Figure 3 The outer surface of the high-denier polyester yarn 6 is covered with an abrasion-resistant fiber layer 7. The abrasion-resistant fiber layer 7 is fixed to the surface of the high-denier polyester yarn 6 by winding. The winding and fixing method can ensure that the abrasion-resistant fiber layer 7 is tightly bonded to the high-denier polyester yarn 6. The abrasion-resistant fiber layer 7 can effectively resist external friction and wear, and extend the service life of the webbing.
[0029] The high-denier polyester yarn 6 is formed by twisting multiple polyester monofilaments together, and the twist direction of the multiple polyester monofilaments is opposite to the winding direction of the abrasion-resistant fiber layer 7, which makes the bond between the high-denier polyester yarn 6 and the abrasion-resistant fiber layer 7 stronger. When subjected to external force, it can better maintain the integrity of the structure and is less prone to delamination or detachment.
[0030] This design features: Core layer 1 with multiple strands of twisted and radially arranged elastic polyester multifilaments 3 wound around its surface to provide basic elasticity, with spiral polyester auxiliary filaments interspersed to enhance bonding strength and tensile strength; Polyester support filaments 4 with a non-circular cross-section wound around its surface in the opposite direction to the elastic polyester multifilaments 3, with the ends abutting to enhance connection stability; Connecting filaments 5 with intervals and Z-shaped staggered distribution on the inner wall of surface layer 2 are woven to connect core layer 1 and surface layer 2; High-denier polyester yarn 6 formed by twisting multiple strands of polyester monofilaments on the surface of surface layer 2 with a twist direction opposite to the winding direction of abrasion-resistant fiber layer 7 is interwoven and fixed, and its outer surface is fixed to abrasion-resistant fiber layer 7 by winding to improve abrasion resistance, ultimately giving the webbing good elasticity and excellent abrasion resistance.
