Description

Technical Field

[0001] This utility model belongs to the field of 3D spacer fabric technology, specifically relating to a noise-reducing and breathable 3D spacer fabric structure. Background Technology

[0002] 3D spacer fabric (commonly known as 3D mesh fabric) is widely used in automotive seats, mattresses, and other fields due to its excellent elasticity, support, and breathability. Its typical structure includes an upper mesh layer, a lower mesh layer, and a middle yarn connecting the two. However, in actual use, especially when the human body moves frequently or is subjected to pressure and deformation, the middle yarns rub against each other due to cross-contact, easily producing uncomfortable noises such as a "rustling" sound, seriously affecting riding comfort and the perceived quality of the product.

[0003] Currently, there are many 3D spacer fabrics on the market, with varying arrangements and densities of the yarns. The yarns generally employ a dense "C"-shaped or cross-laid support structure. To improve breathability, the density of the yarns is sometimes reduced to create ventilation channels. However, friction between the yarns in this type of 3D spacer fabric is unavoidable. To reduce friction and thus noise, some noise reduction solutions have emerged. Conventional solutions primarily focus on reducing the yarn density, but excessively reducing the density can lead to insufficient support and collapse. Slightly reducing the density doesn't eliminate noise issues and sacrifices some support and elasticity. Furthermore, traditional nodes use tight weaving or fusion bonding, resulting in poor extensibility, further exacerbating the rigid collisions and friction of the yarns under pressure.

[0004] In view of the aforementioned problems, it is necessary to design a 3D spaced fabric structure that can fundamentally suppress the friction of the central yarn and achieve a significant noise reduction effect without affecting the fabric's support and breathability. To this end, the applicant has ingeniously designed this technical solution. Utility Model Content

[0005] The objective of this invention is to provide a noise-reducing and breathable 3D spacer fabric structure that helps improve the arrangement of the center yarns and the connection structure of the nodes, effectively preventing the center yarns from contacting and rubbing against each other when under pressure, thereby significantly reducing noise during use; while also taking into account the breathability and support elasticity of the fabric.

[0006] The present invention achieves its objective as follows: a noise-reducing and breathable 3D spacer fabric structure, comprising a top mesh, a bottom mesh spaced below the top mesh, and a set of middle threads positioned between the top and bottom meshes and woven and fixed at both ends onto the top and bottom meshes respectively. The top mesh comprises a set of parallel, spaced, and staggered wavy-shaped mesh weaving skeletons; adjacent mesh weaving skeletons are connected at close proximity by a set of mesh connecting threads to form upper nodes; and a set of mesh holes is formed between adjacent mesh weaving skeletons. The bottom mesh comprises a set of parallel, spaced, and staggered wavy-shaped bottom mesh weaving skeletons; adjacent mesh weaving skeletons are connected at close proximity by a set of mesh connecting threads to form upper nodes; and a set of mesh holes is formed between adjacent mesh weaving skeletons. The lower mesh fabric weaving skeletons are connected to each other at close positions by a set of lower mesh fabric connecting wires to form lower nodes. A set of lower mesh holes is formed between two adjacent lower mesh fabric weaving skeletons. The upper mesh holes and lower mesh holes are arranged in an alternating vertical state. Two middle wires are connected to each upper node. The upper end of each middle wire is connected to the upper node, and the lower end is connected to the two adjacent lower nodes below. A breathable channel is formed between the upper mesh fabric connecting wire and the corresponding lower mesh fabric connecting wire. The middle wires are arranged in an X-shaped structure on the left and right sides of the upper and lower mesh fabrics, and are intersected and spaced apart. The adjacent intersecting middle wires are spaced apart along the left and right directions.

[0007] In a specific embodiment of this utility model, a breathable channel is formed between the connecting wire of the net fabric and the corresponding connecting wire of the lower net fabric. The distance between two adjacent net fabric weaving skeletons is increased by connecting them with a set of net fabric connecting wires, and the distance between two adjacent lower net fabric weaving skeletons is increased by connecting them with a set of lower net fabric connecting wires, thereby increasing the width of the breathable channel.

[0008] In another specific embodiment of this utility model, the middle yarn is a solid polyester monofilament, and the number of the middle yarn consists of three to six monofilaments.

[0009] In another specific embodiment of this utility model, the upper mesh hole and the lower mesh hole are one of the following: circular, elliptical, or parallelogram.

[0010] In another specific embodiment of this utility model, the middle wires are arranged in a tightly packed “C” shape on the front and back sides of the netting and the bottom netting.

[0011] In a further specific embodiment of this utility model, each upper node has at least one mesh fabric connecting wire, and each lower node has at least one lower mesh fabric connecting wire.

[0012] In a further specific embodiment of this utility model, the net fabric and the bottom fabric are each woven from a mixture of 600D DTY yarn and 900D DTY yarn, wherein the connecting yarn of the net fabric and the connecting yarn of the bottom fabric are composed of 600D DTY yarn.

[0013] The beneficial effects of this utility model after adopting the above structure are as follows: First, because the middle yarns are arranged in an "X" shape on the left and right sides of the top and bottom mesh fabrics, intersecting and spaced apart, and the middle yarns are spaced apart in the left and right directions, the intersecting and spaced middle yarns will not generate friction when squeezed, greatly reducing the noise caused by friction. Second, because the mesh fabric weaving skeleton is connected and spaced apart by mesh fabric connecting yarns, and multiple middle yarns are cross-supported between the top and bottom mesh fabrics, the width of the air passage is increased while improving the fabric's support and elasticity, effectively improving the fabric's air permeability, and indirectly increasing the distance between adjacent middle yarns, further reducing the friction between the middle yarns and thus effectively reducing noise.

[0016] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. However, the description of the embodiments is not a limitation on the technical solution. Any formal but not substantive changes made based on the concept of this utility model should be considered within the protection scope of this utility model.

[0017] In the following description, all directional or positional concepts involving up, down, left, right, front, and back are based on... Figure 1 The positions shown are for reference only and should not be construed as a particular limitation on the technical solutions provided by this utility model.

[0018] Please see Figures 1 to 5 This utility model relates to a noise-reducing and breathable 3D spacer fabric structure, including a net fabric 1 and a lower net fabric 2 spaced below the net fabric 1, and a set of middle yarns 3 disposed between the net fabric 1 and the lower net fabric 2 and woven and fixed at both ends on the net fabric 1 and the lower net fabric 2 respectively.

[0019] The technical innovation of this utility model lies in the following: the aforementioned netting 1 includes a set of parallel, staggered, wave-shaped netting woven skeletons 11. Adjacent netting woven skeletons 11 are connected at close proximity by a set of netting connecting wires 12 to form upper nodes 100. A set of netting holes 13 are formed between adjacent netting woven skeletons 11. The aforementioned lower netting 2 includes a set of parallel, staggered, wave-shaped lower netting woven skeletons 21. Adjacent lower netting woven skeletons 21 are connected at close proximity by a set of lower netting... Connecting wires 22 are connected to form lower nodes 200. A set of lower mesh holes 23 are formed between two adjacent lower mesh fabric weaving skeletons 21. The upper mesh holes 13 and lower mesh holes 23 are not directly opposite each other, but are arranged in an alternating vertical state. Two middle wires 3 are connected to each upper node 100. The upper end of each middle wire 3 is connected to the upper node 100, and the lower end is connected to the two adjacent lower nodes 200 below. The middle wires 3 are arranged in an X-shaped structure on the left and right sides of the upper and lower mesh fabrics 1 and 2, and are intersected and spaced apart. The adjacent intersecting middle wires 3 are spaced apart along the left and right directions (e.g., ...). Figure 3 (As shown).

[0020] Please see Figure 1 and combined Figure 3 The aforementioned net fabric connecting wire 12 and the corresponding lower net fabric connecting wire 22 form a breathable channel 4. The upper and lower sides of the breathable channel 4 correspond to the net fabric connecting wire 12 and the lower net fabric connecting wire 22 at their respective positions. The distance between two adjacent net fabric weaving frames 11 is increased by connecting them with the net fabric connecting wire 12, and the distance between two adjacent lower net fabric weaving frames 21 is increased by connecting them with the lower net fabric connecting wire 22, thereby increasing the width of the breathable channel 4.

[0021] Please see Figure 1 The aforementioned middle yarn 3 is a solid polyester monofilament, and a strand of the aforementioned middle yarn 3 consists of three to six monofilaments. In this embodiment, a strand of the aforementioned middle yarn 3 preferably consists of four monofilaments.

[0022] Please see Figure 1 and Figure 4 , Figure 5 The aforementioned mesh opening 13 and lower mesh opening 23 are one of a circle, an ellipse, or a parallelogram. In this embodiment, the aforementioned mesh opening 13 and lower mesh opening 23 are preferably elliptical.

[0023] Please see Figure 2 and Figure 3 The aforementioned middle wire 3 is arranged in a tightly packed “C” shape on the front and back sides of the upper and lower mesh fabric 1 and the lower mesh fabric 2.

[0024] Please see Figure 1 Each of the aforementioned upper nodes 100 has at least one netting connecting wire 12, and each of the aforementioned lower nodes 200 has at least one lower netting connecting wire 22. In this embodiment, each of the aforementioned upper nodes 100 has four netting connecting wires 12, and each of the aforementioned lower nodes 200 has four lower netting connecting wires 22.

[0025] In this embodiment, the aforementioned net fabric 1 and lower net fabric 2 are each woven from a mixture of 600D DTY yarn and 900D DTY yarn, wherein the aforementioned net fabric connecting yarn 12 and lower net fabric connecting yarn 22 are composed of 600D DTY yarn.

[0026] Please continue reading. Figures 1 to 5 When the aforementioned net fabric 1 is pressed down and the middle yarn 3 is squeezed, the aforementioned middle yarn 3 bends under pressure. Some of the aforementioned middle yarn 3 bends into the ventilation channel 4. However, because the distance between the two adjacent net fabric weaving skeletons 11 is increased by the net fabric connecting wire 12, and the distance between the two adjacent lower net fabric weaving skeletons 21 is increased by the lower net fabric connecting wire 22, the width of the aforementioned ventilation channel 4 is greatly extended. At the same time, the adjacent intersecting middle yarns 3 are spaced apart in the left and right directions, so that the intersecting positions do not contact each other. Therefore, the aforementioned bent middle yarns 3 will not affect the ventilation effect of the ventilation channel 4, nor will they cause mutual friction and noise. This effectively solves the problems of insufficient breathability and easy noise generation when squeezed in current 3D spacer fabrics. For example, the 3D spacer fabric of this utility model can be used in the backrest padding of car seats. Compared with the original technology, it can reduce annoying friction noises such as rustling, and can also maintain the breathability of the backrest.

[0027] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0028] In summary, the technical solution provided by this utility model makes up for the shortcomings of the prior art, successfully completes the utility model task, and faithfully realizes the technical effects described by the applicant in the above technical effect column.
