Description

Technical Field

[0001] This utility model belongs to the field of knitted fabric technology, specifically tensile knitted fabric. Background Technology

[0002] Knitted fabrics are widely used in outdoor equipment, industrial protection, and sportswear due to their softness, breathability, and comfort. However, these applications place high demands on the tensile strength, tear resistance, and structural stability of knitted fabrics. For example, outdoor tent fabrics need to withstand strong winds, industrial protective gloves need to resist mechanical friction and stretching, and sports compression garments need to accommodate large-scale limb movements and avoid permanent deformation. Traditional knitted fabrics are gradually becoming unable to meet these high-intensity usage requirements. Therefore, developing knitted fabrics that combine softness with excellent tensile strength has become a key direction for the industry.

[0003] In the existing technology, the tensile strength of knitted fabrics is mainly improved by selecting high-strength fiber materials, such as using single high-strength fibers like polyester and nylon to weave the fabric, or by simply blending high-strength fibers with elastic fibers to enhance the tensile strength of the fabric by utilizing the mechanical properties of the fibers themselves.

[0004] The existing technology has the following shortcomings: Most of them use single fiber blends or simple interweaving, without differentiated design for the performance requirements of knitted fabrics in different directions. For example, they only improve the overall tensile strength by blending, but it is difficult to take into account the elastic stretching requirements in the lateral direction and the load-bearing and tear resistance requirements in the longitudinal direction. This results in the fabric being prone to insufficient rebound after lateral stretching and local tearing when subjected to longitudinal force in actual use. In existing braided structures, fiber bundles with different functions are mostly simply superimposed or interwoven without a dedicated connecting and reinforcing structure. This makes it easy for relative slippage to occur between the bundles. Especially after long-term repeated stretching, the fabric is prone to loosening of coils and structural deformation, which in turn leads to a significant reduction in tensile strength. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a tensile-resistant knitted fabric, which solves the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tensile knitted fabric, comprising a fabric body, wherein the fabric body is woven from structural yarn bundles and traction yarn bundles, the structural yarn bundles are made of composite elastic fibers, the traction yarn bundles are blended yarns of high-strength polyester fibers and glass fibers, the fabric body is woven with a double rib structure, and a reinforcing yarn bundle is woven between the structural yarn bundles and the traction yarn bundles, the reinforcing yarn bundles being made of high-strength nylon fibers.

[0007] As a further embodiment of this utility model: the structural wire harnesses are interconnected by coils to form an elastic support structure in the transverse direction of the fabric.

[0008] As a further embodiment of this utility model: the traction harness and the wavy protrusion of the structural harness are interwoven and connected to form a tensile skeleton in the longitudinal direction of the fabric.

[0009] As a further embodiment of this utility model: the reinforcing wire harness is interlaced between the structural wire harness and the traction wire harness, and the reinforcing wire harness, the structural wire harness, and the traction wire harness form multiple interlacing points.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The structural harness made of composite elastic fibers, combined with a double rib structure, gives the fabric excellent lateral elasticity, preventing permanent deformation caused by stretching during use. The longitudinal tensile skeleton constructed by the traction harness of high-strength polyester fiber and glass fiber can significantly improve the longitudinal load-bearing capacity and tear resistance of the fabric, meeting the high-strength use requirements in outdoor, industrial and other scenarios. The interweaving of reinforcing strands made of high-strength nylon fibers between the structural and traction strands further enhances the overall structural stability of the fabric and reduces the risk of slippage between different strands. At the same time, the material properties of the three strands work together with the weaving structure to ensure that the fabric has high tensile strength while maintaining the softness and fit of knitted fabric, thus balancing practicality and comfort and making it more widely applicable.

[0013] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0014] like Figures 1-5 As shown, this utility model provides a technical solution: Tensile knitted fabric includes fabric body 1, which is woven from structural yarn bundle 2 and traction yarn bundle 4. Structural yarn bundle 2 is made of composite elastic fiber, and traction yarn bundle 4 is a blended yarn of high-strength polyester fiber and glass fiber. Fabric body 1 is woven with a double rib structure, and a reinforcing yarn bundle 3 is woven between structural yarn bundle 2 and traction yarn bundle 4. The reinforcing yarn bundle 3 is made of high-strength nylon fiber. Specifically, the structural wire bundle 2 made of composite elastic fiber, combined with the double rib structure, can give the fabric 1 excellent lateral elasticity and avoid permanent deformation due to stretching during use. The longitudinal tensile skeleton constructed by the traction wire bundle 4 made of high-strength polyester fiber and glass fiber can significantly improve the longitudinal load-bearing capacity and tear resistance of the fabric 1, meeting the high-strength use requirements in outdoor, industrial and other scenarios. The reinforcing wire harness 3 made of high-strength nylon fiber interweaves between the structural wire harness 2 and the traction wire harness 4, which can further enhance the overall structural stability of the fabric 1 and reduce the risk of slippage between different wire harnesses. At the same time, the material properties of the three wire harnesses and the weaving structure work together to ensure that the fabric 1 has high tensile strength while maintaining the softness and fit of the knitted fabric, taking into account both practicality and comfort, and making it more widely applicable. The structural wire harness 2 is interconnected by coils to form an elastic support structure in the transverse direction of the fabric 1. The traction wire harness 4 is interwoven with the wavy protrusion of the structural wire harness 2 to form a tensile skeleton in the longitudinal direction of the fabric 1. The reinforcing wire harness 3 is inserted between the structural wire harness 2 and the traction wire harness 4, and the reinforcing wire harness 3, the structural wire harness 2 and the traction wire harness 4 form multiple interlacing points. Specifically, the structural wire harness 2 is first laid out horizontally and interlocked with coils to form a continuous elastic support structure. At the same time, the traction wire harness 4 is precisely interwoven with the wavy protrusion of the structural wire harness 2 in the longitudinal direction to build a longitudinal tensile skeleton. Then, the reinforcing wire harness 3 is inserted between the structural wire harness 2 and the traction wire harness 4 to ensure that it forms multiple interlacing points with both. Finally, the overall weaving of the fabric 1 is completed through the coordinated operation of the knitting equipment. It can be cut and applied according to actual needs. The transverse elastic support structure formed by the coil sleeve of the structural wire harness 2 allows the fabric 1 to have good lateral elasticity, adapt to tensile deformation during use and rebound quickly. The longitudinal tensile skeleton formed by the interlacing connection of the traction wire harness 4 and the wavy protrusion of the structural wire harness 2 can greatly improve the longitudinal tensile strength of the fabric 1 and avoid longitudinal tearing under stress. The multiple interlacing points formed by the reinforcing wire harness 3 and the other two wire harnesses can organically combine the transverse elastic support and the longitudinal tensile skeleton into a whole, reduce the relative slippage between the wire harnesses, and further enhance the structural stability and overall tensile performance of the fabric 1. This makes the fabric 1 have better comprehensive mechanical properties while having both transverse elasticity and longitudinal strength, meeting the usage requirements in various scenarios. The working principle of this utility model is as follows: First, a structural bundle 2 made of composite elastic fiber serves as the transverse elastic core, and a traction bundle 4 made of high-strength polyester fiber and glass fiber blend serves as the longitudinal tensile core. The two bundles are woven into fabric 1 through a double rib structure. The structural bundle 2 forms an elastic support structure in the transverse direction of fabric 1 by interlocking loops, providing transverse stretching and rebound capabilities for fabric 1. The traction bundle 4 is interwoven with the wavy protrusions of the structural bundle 2, forming a tensile skeleton in the longitudinal direction of fabric 1, laying the foundation for the longitudinal tensile and tear resistance of fabric 1. Secondly, the reinforcing wire bundle 3 made of high-strength nylon fiber is interwoven between the structural wire bundle 2 and the traction wire bundle 4, and forms multiple interlacing points with the two, which can organically connect the transverse elastic support structure and the longitudinal tensile skeleton into a whole, effectively reducing the relative slippage between different wire bundles, avoiding structural separation when subjected to force in a single direction, and further improving the overall structural stability of the fabric 1. It is worth mentioning that the elasticity of the structural wire harness 2, combined with the stretching advantage of the double rib structure, can prevent the fabric 1 from being permanently deformed due to stretching during use. The high-strength blended material of the traction wire harness 4 can maximize the longitudinal load-bearing capacity. The high wear resistance and high toughness of the reinforcing wire harness 3 fills the performance gap at the connection between the transverse and longitudinal wire harnesses. The three work together to allow the fabric to maintain softness and fit while having high tensile strength. Finally, the knitting process of each yarn bundle is precisely controlled by the knitting equipment 1. First, the horizontal elastic support structure of the structural yarn bundle 2 and the longitudinal tensile skeleton of the traction yarn bundle 4 are knitted synchronously. Then, the reinforcing yarn bundle 3 is interwoven to form a reinforcement, ensuring that the fabric 1 can stably perform comprehensive mechanical properties in various scenarios, taking into account both practicality and user comfort.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
