Description

Technical Field

[0001] This utility model relates to the field of heddle weaving technology, specifically to a high-elastic double-strand heddle weaving fabric. Background Technology

[0002] Double-ply interlaced heddle woven fabrics, due to their unique weaving structure, typically possess good dimensional stability, a certain degree of abrasion resistance, and a distinctive appearance, making them suitable for various textile applications. However, traditional double-ply interlaced heddle woven fabrics, due to limitations in yarn characteristics and weave structure, often fall short in terms of elasticity and breathability, making it difficult to meet the growing demands of modern clothing (especially sportswear and underwear) for high elasticity, high breathability, and a superior wearing experience. Utility Model Content

[0003] The purpose of this invention is to overcome the aforementioned defects or problems in the prior art and to provide a high-elastic double-strand heddle woven fabric, which can improve the technical problem that existing double-strand interlaced heddle woven fabrics are difficult to balance in terms of elasticity and breathability.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Technical Solution 1: A high-elastic double-strand heddle woven fabric, comprising: a woven body, which is a double-strand interlaced heddle woven fabric; at least one elastic sponge layer, which is bonded to at least one surface of the woven body; at least one spandex film, which is laminated to the outer surface of the elastic sponge layer; at least one elastic mesh film, which is laminated to the outer surface of the spandex film; wherein, the woven body and each of the elastic sponge layers together constitute a lower porous composite component having multiple through holes; the spandex film and the elastic mesh film together constitute a continuous and non-porous upper film composite component; at the interface between the upper film composite component and the lower porous composite component, a direct contact area is formed at the edge region of each of the through holes on the surface of the lower porous composite component, and a suspended area is formed above the opening of each of the through holes, where the upper film composite component crosses the opening, and the direct contact area and the suspended area are alternately arranged along the interface.

[0006] Technical Solution 2 based on Technical Solution 1: The two elastic sponge layers are respectively stacked and bonded to the two side surfaces of the woven body; the two spandex films are respectively stacked and bonded to the outer surface of the two elastic sponge layers; the two elastic mesh films are respectively stacked and bonded to the outer surface of the two spandex films.

[0007] Technical Solution 3 based on Technical Solution 2: The elastic sponge layer is bonded to the woven body through a hot-pressing composite process; the spandex film is bonded to the outer surface of one of the elastic sponge layers through a PUR adhesive bonding process; the elastic mesh film is bonded to the outer surface of the spandex film through a polyurethane adhesive bonding process.

[0008] Technical solution four, based on any one of technical solutions one to three, further includes an elastic edge banding, which is arranged along the periphery of the fabric body formed by the lower porous composite component and the upper thin film composite component, and covers the edge end face of the fabric body.

[0009] Technical solution five based on technical solution four: An elastic coating layer is provided on the outer surface of the elastic mesh film and the exposed surface of the elastic reinforcing edge structure, and the elastic coating layer continuously covers the surfaces to which they are attached.

[0010] Technical Solution Six based on Technical Solution One: The multiple through holes in the lower porous composite component form a hole array. The hole diameter, minimum wall thickness between holes, and arrangement density of the hole array are adapted to the double-strand yarn specifications and cross-hedral structure density of the woven body, so that the through-form of the hole array forms the geometric boundary of the suspended area in the interface.

[0011] Technical solution seven based on technical solution six: The elastic mesh film is made of a material containing thermoplastic polyurethane or thermoplastic polyester elastomer.

[0012] Technical solution eight based on technical solution seven: The elastic coating layer is formed by a composition containing polyurethane-based elastic material or silicone-based elastic material.

[0013] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following beneficial effects:

[0014] Technical Solution 1 provides a high-elastic double-strand heddle woven fabric, which effectively improves the technical problem of existing double-strand heddle woven fabrics struggling to balance elasticity and breathability. In this technical solution, the fabric structure is divided into a lower porous composite component with multiple through-holes and a continuous, non-porous upper film composite component. Compared to existing technologies that simply laminate an elastic film onto the surface of the woven fabric, resulting in poor breathability, or those that perforate ordinary elastic composite fabrics, potentially causing the film to tear, collapse, or cause discomfort at the hole edges, this solution creates a direct contact area at the interface between the upper film composite component and the lower porous composite component, at the edge region of each through-hole on the surface of the lower porous composite component. An additional suspended area is formed above each through-hole opening, allowing the upper film composite component to cross the opening. The direct contact area and the suspended area are alternately arranged along the interface, forming a non-homogeneous interface structure. This heterogeneous interface structure is key to achieving both high elasticity and high breathability in this solution: the spandex film and elastic mesh film in the upper film composite component ensure the overall tensile resilience of the fabric; while the through-holes in the lower porous composite component, and the suspended area formed above the through-holes in the upper film composite component, together constitute effective air and moisture circulation channels, significantly improving the fabric's breathability. Simultaneously, because the upper film composite component forms a direct contact area with the lower solid part at the edge of the through-holes, it provides stable support for the film, preventing collapse or damage due to stress concentration in the pore area, thus ensuring the stability and durability of the structure. Therefore, this technical solution does not improve the problems of existing double-strand cross-woven fabrics through a simple composite structure of different layers, but rather organically combines different layers with specific physical structures. By forming an innovative interface structure between the upper film composite component and the lower porous composite component, it successfully combines the elastic component and the breathable structure, overcoming the shortcomings of existing technologies that cannot effectively balance these two aspects of performance.

[0015] In technical solution two, a symmetrical multi-layered composite structure is adopted, specifically by incorporating an elastic sponge layer, a spandex film, and an elastic mesh film on both sides of the woven fabric, further optimizing the overall performance of the fabric. This symmetrical structure results in a more uniform stress distribution when the fabric is subjected to external forces, and the deformation and recovery characteristics exhibit better consistency and balance in the two main directions of the fabric. Simultaneously, the soft touch provided by the elastic sponge layer on both sides and the elasticity provided by the elastic film layer ensure a similar comfortable wearing experience regardless of which side of the fabric comes into contact with the skin.

[0016] In technical solution three, a hot-pressing composite process is used between the elastic sponge layer and the woven body, a PUR adhesive bonding process is used between the spandex film and the elastic sponge layer, and a polyurethane adhesive bonding process is used between the elastic mesh film and the spandex film. The selection and application of these specific bonding processes ensure a stable, strong, and clearly defined bond between the composite layers, guaranteeing the effective formation and functionality of both the direct contact area and the suspended area. This stable interlayer bonding also prevents interlayer separation or bubbling that may occur during use due to repeated stretching, bending, or washing, thus ensuring the durability of the fabric's overall mechanical properties and appearance quality.

[0017] In technical solution four, an elastic edging structure is set around the perimeter of the fabric body to cover its edge faces, effectively protecting the fabric edges. The edges of multi-layered composite fabrics are often structurally weak points, prone to delamination, yarn slippage, or wear. The elastic edging not only physically covers and fixes these edge faces, preventing these problems, but also adapts to the elastic deformation of the fabric body, avoiding localized stress concentration or wrinkles caused by a mismatch between the edging material and the elasticity of the fabric body. This significantly improves the fabric's durability and overall aesthetics.

[0018] In technical solution five, an elastic coating layer is applied to the exposed surfaces of both the elastic mesh film and the elastic reinforced edging structure, further enhancing the surface properties and durability of the fabric. The elastic coating layer forms a continuous protective film on the surfaces it adheres to, effectively improving the wear resistance and scratch resistance of these areas, and imparting certain stain resistance or easy-to-clean properties. Simultaneously, the elasticity of the coating layer itself works in synergy with the elasticity of the base material, helping to maintain the smoothness and elastic recovery of the fabric surface, improving the fabric's hand feel and appearance, and providing further protection for the internal elastic mesh film and edging structure.

[0019] In technical solution six, by adapting the pore size, minimum inter-pore wall thickness, and arrangement density of the through-hole array in the lower porous composite component to the specifications of the double-strand yarn and the density of the interlaced heddle structure of the woven body, a good match between the through-hole structure and the characteristics of the base fabric is ensured. This adaptation allows the opening of the through holes to effectively form the suspended areas in the aforementioned interface, thereby ensuring excellent air permeability, without excessively weakening the structural strength of the woven body, avoiding fabric tearing or deformation problems caused by improper opening. Reasonable inter-pore wall thickness and arrangement density ensure the mechanical stability of the lower porous composite component, enabling it to effectively support the upper film composite component and coordinate with the inherent texture and mechanical properties of the woven body, thereby optimizing the overall balance of strength, elasticity, and air permeability of the fabric.

[0020] Technical Solution 7 specifies that the elastic mesh membrane is made of a material containing thermoplastic polyurethane or thermoplastic polyester elastomer. These polymeric elastomer materials themselves possess excellent tensile resilience, good abrasion resistance, flexural resistance, and processability. Applying such materials to the elastic mesh membrane ensures that the mesh membrane, while imparting good elasticity to the fabric, also possesses sufficient strength and durability to withstand stress changes during repeated use.

[0021] Technical Solution 8 specifies that the elastic coating layer is formed from a composition containing either polyurethane-based or silicone-based elastic materials. Polyurethane-based elastic materials typically possess excellent abrasion resistance, high elasticity, and good adhesion, forming a tough and elastic protective coating. Silicone-based elastic materials, on the other hand, are known for their excellent flexibility, hydrophobicity, weather resistance, and biocompatibility, providing fabric surfaces with a soft feel and some waterproof and breathable properties. Using these two types of materials to prepare the elastic coating layer allows for optimization of the fabric surface's durability, elasticity, feel, and functional characteristics according to specific needs, further enhancing the overall quality of the product.

[0033] Example

[0034] This utility model embodiment relates to a high-elastic double-strand heddle woven fabric, referring to... Figure 1 The woven fabric includes a fabric body 1 and an elastic binding 2, as shown in the figure. Figure 2 and Figure 3The fabric body 1 includes: a woven body 13, which is a woven fabric with double-strand interlaced heddles; at least one elastic sponge layer 12, which is bonded to at least one surface of the woven body 13; at least one spandex film 15, which is laminated to the outer surface of the elastic sponge layer 12; and at least one elastic mesh film 11, which is laminated to the outer surface of the spandex film 15. The woven body 13 and each of the elastic sponge layers 12 together constitute a lower porous composite assembly with a plurality of through-holes 14. The thin film 15 and the elastic mesh film 11 together constitute a continuous and non-porous upper thin film composite assembly; at the interface between the upper thin film composite assembly and the lower porous composite assembly, a direct contact area is formed at the edge region of each of the through holes 14 on the surface of the lower porous composite assembly, and a suspended area is formed above the opening of each of the through holes 14, where the upper thin film composite assembly crosses the opening, and the direct contact area and the suspended area are arranged alternately along the interface.

[0035] Specifically, the woven body 13 can be made of natural fibers such as cotton, linen, silk, and wool, or chemical fibers such as polyester, nylon, and polypropylene, or blended yarns of these fibers, and is manufactured through double-strand plying and heddle weaving. The double-strand plydle structure gives the woven body 13 a certain degree of stiffness and basic strength. The elastic sponge layer 12 can be made of porous materials with good softness and resilience, such as polyurethane sponge or latex sponge, and its thickness can be selected according to the softness requirements of the final product, for example, 0.5 mm to 3 mm. The spandex film layer is a polyurethane elastic fiber film with high elongation and high elastic recovery rate, and its thickness can be 15 micrometers to 50 micrometers. The elastic mesh film 11 is an elastic film with a mesh structure, and its mesh shape can be rhomboid, square, or hexagonal, etc. The width and thickness of the ribs can be adjusted according to the required support strength and elasticity. The through-holes 14 in the lower porous composite component can be formed by laser drilling, mechanical punching, or needle punching. The pore size and arrangement density are set according to the balance requirements of air permeability and structural strength. The continuous non-porous nature of the upper thin-film composite component ensures its integrity as an elastic functional layer and structural support layer. The direct contact area is the area where the solid parts between the upper thin-film composite component and the through-holes 14 in the lower porous composite component are tightly bonded by adhesive or hot-melt method. Structurally, this direct contact area is a closed or semi-closed annular or strip-shaped adhesive area surrounding the edge of each through-hole 14. Its width can be controlled according to the adhesive process and the required bonding strength, for example, from 0.2 mm to 1.0 mm, ensuring that the upper thin-film composite component is firmly anchored at the edge of the through-hole 14. The suspended area is the region formed by the upper thin-film composite component spanning the opening of the through hole 14, which is not in direct contact with the lower layer, thanks to its own tension and the support of the elastic mesh membrane 11. Structurally, this suspended area is a relatively flat or slightly curved thin-film bridging structure formed by the upper thin-film composite component above the opening of the through hole 14. Its span is the diameter of the through hole 14. A gap with a certain height is formed between this thin film and the bottom surface or opposite opening of the through hole 14 of the lower porous composite component. The height of this gap depends on the thickness of the lower porous composite component and the tension of the upper thin-film composite component.

[0036] The elastic edging 2 is disposed along the periphery of the fabric body formed by the lower porous composite component and the upper thin film composite component, and covers the edge end face of the fabric body. Specifically, the elastic edging 2 can be made of elastic webbing or elastic strips that match the elasticity of the fabric body, and is fixed to the edge of the fabric body by means of sewing, hot melt bonding, or ultrasonic welding. For example, spandex edging tape with a width of 1 cm to 2 cm can be selected, and the edging can be overlocked using a three-thread or four-thread overlock machine to ensure that the edging is firm and has good tensile recovery, effectively preventing the fabric edge from unraveling and curling. The edging structure is usually U-shaped or C-shaped in cross-section, covering the edge end of the fabric body within it.

[0037] In this embodiment, two layers of elastic sponge 12 are respectively stacked and bonded to the two side surfaces of the woven body 13; two spandex films 15 are respectively stacked and bonded to the outer surface of the two layers of elastic sponge 12; and two elastic mesh films 11 are respectively stacked and bonded to the outer surface of the two layers of spandex films 15. Specifically, this symmetrical stacking structure gives the inner and outer sides of the fabric body 1 similar structure and properties. For example, the thickness of the woven body 13 can be 0.3 mm to 1.0 mm, and each side is laminated with a layer of elastic sponge 12 with a thickness of 0.5 mm to 1.5 mm. Then, on the outside of each layer of elastic sponge 12, a layer of spandex film with a thickness of 20 micrometers to 40 micrometers and a layer of elastic mesh film 11 with a mesh density of 100 to 400 per square centimeter are sequentially laminated. This symmetrical structure makes the stress distribution on both sides of the fabric more uniform when it is bent or stretched, improving the overall durability and wearing comfort.

[0038] In this embodiment, the elastic sponge layer 12 is bonded to the woven body 13 via a hot-pressing composite process; the spandex film 15 is bonded to the outer surface of one of the elastic sponge layers 12 via a PUR adhesive bonding process; and the elastic mesh film 11 is bonded to the outer surface of the spandex film 15 via a polyurethane adhesive bonding process. Specifically, in the hot-pressing composite process, the elastic sponge layer 12 and the woven body 13 can be hot-pressed together at a certain temperature (e.g., 120°C to 160°C) and pressure (e.g., 0.2 MPa to 0.5 MPa) for 15 to 30 seconds to ensure a tight bond. PUR adhesive, or polyurethane reactive hot melt adhesive, has the characteristics of high initial tack, fast curing speed, and good bonding strength, and is suitable for bonding the spandex film layer to the porous elastic sponge layer 12. The amount of adhesive applied can be controlled between 20 and 50 grams per square meter. Polyurethane adhesives possess excellent elasticity and water resistance, making them suitable for bonding elastic mesh film 11 to spandex film layers. Application can be done by scraping or spraying, ensuring a uniform adhesive layer. These specific lamination processes guarantee a strong bond between the layers, preventing delamination.

[0039] Furthermore, an elastic coating layer is provided on the outer surface of the elastic mesh film 11 and the exposed surface of the elastic reinforcing edging structure, continuously covering the surfaces to which they are attached. Specifically, the elastic coating layer can be an elastic film with a thickness of 10 to 30 micrometers, formed by dip coating, scraping, or spraying processes. For example, liquid polyurethane prepolymer or silicone emulsion can be selected as the coating material to form a uniform coating on the outer surface of the elastic mesh film 11 and the elastic edging 2, and then cured by heating or room temperature. This coating not only improves the surface abrasion resistance but may also impart certain stain resistance and improved hand feel to the fabric.

[0040] Furthermore, referring to Figure 3 The multiple through holes 14 in the lower porous composite component form a hole array. The hole diameter, minimum wall thickness between holes and the arrangement density of the hole array are adapted to the double yarn specifications and cross-hedral structure density of the woven body 13, so that the through shape of the hole array forms the geometric boundary of the suspended area in the interface.

[0041] For example, for a cotton double-strand interlaced heddle woven body 13 with a yarn specification of 40S / 2, its warp and weft density can be 120 threads per inch x 80 threads per inch. Based on this, the through holes 14 in the lower porous composite component can be designed as circular holes with a diameter of 0.5 mm to 1.5 mm and a hole spacing (distance between the centers of adjacent holes) of 2 mm to 4 mm, forming a quincunx or rectangular array of holes. This hole diameter and density ensures sufficient air permeability and creates a suitable span for the suspended area, while the solid portion (minimum wall thickness) between the holes maintains sufficient structural strength to support the upper film composite component and coordinate with the weave structure of the woven body 13, preventing fabric tearing due to excessively dense or large hole diameters. Structurally, the sidewall of each through hole 14 can be perpendicular to the fabric surface or slightly inclined depending on the perforation process. The solid portion between the holes is the area of ​​material that was not removed from the lower porous composite component, and its width is the minimum wall thickness between the holes, which can be, for example, 0.5 mm to 2 mm.

[0042] The elastic mesh film 11 is made of a material comprising thermoplastic polyurethane or thermoplastic polyester elastomer. For example, thermoplastic polyurethane elastomer particles of grade TPU-95A can be used, and the elastic mesh film 11 with a specific mesh structure can be formed by melt-blowing or lamination embossing processes. This material has a high elongation at break (e.g., greater than 400%) and good elastic recovery (e.g., greater than 95%), and excellent abrasion resistance and aging resistance. Alternatively, materials such as those from DuPont can also be used. This series of thermoplastic polyester elastomers also possesses excellent elasticity and durability. The ribs of this elastic mesh film 11 can have circular, flat, or irregular cross-sections, and the intersections between the ribs can be achieved through hot-melt bonding or integral molding.

[0043] Furthermore, the elastic coating layer is formed from a composition comprising a polyurethane-based elastic material or a silicone-based elastic material. For example, an aqueous polyurethane dispersion can be used as the coating liquid, wherein the polyurethane solid content is 30% to 50%, with the addition of appropriate leveling agents and crosslinking agents. The coating is then applied to the surfaces of the elastic mesh film 11 and the elastic edge banding 2 by a scraping method, and subsequently dried and cured at 80°C to 120°C. Alternatively, a two-component room-temperature vulcanizing silicone rubber coating can be selected, mixed according to a recommended ratio, and sprayed, then cured at room temperature for 24 hours. This coating layer not only enhances abrasion resistance, but the polyurethane coating also improves the surface tear resistance, while the silicone coating provides a soft, smooth feel and a certain degree of hydrophobicity.

[0044] This embodiment relates to a high-elastic double-strand heddle woven fabric, which effectively improves the technical problem of existing double-strand heddle woven fabrics that are difficult to balance elasticity and breathability. In this technical solution, the fabric structure is divided into a lower porous composite component with multiple through holes 14 and a continuous and non-porous upper film composite component. Compared with the existing technology that simply laminates the elastic film onto the surface of the woven fabric, resulting in poor breathability, or the problem that punching holes in ordinary elastic composite fabric may cause the film to tear, collapse, or cause discomfort at the edge of the holes, this solution forms a direct contact area at the interface between the upper film composite component and the lower porous composite component, at the edge area of ​​each through hole 14 on the surface of the lower porous composite component, and forms a suspended area above the opening of each through hole 14, with the upper film composite component spanning the opening. The direct contact area and the suspended area are arranged alternately along the interface, forming a non-homogeneous interface structure. This heterogeneous interface structure is key to achieving both high elasticity and high breathability in this solution: the spandex film 15 and elastic mesh film 11 in the upper film composite component ensure the overall tensile resilience of the fabric; while the through-holes 14 in the lower porous composite component, and the suspended area formed above the through-holes 14 in the upper film composite component, together constitute effective air and moisture circulation channels, significantly improving the breathability of the fabric. Simultaneously, because the upper film composite component forms a direct contact area with the lower solid part at the edge of the through-holes 14, it provides stable support for the film, preventing collapse or damage due to stress concentration in the porous area, thus ensuring the stability and durability of the structure. Therefore, this technical solution does not improve the problems of existing double-strand cross-woven fabrics through a simple composite structure of different layers, but rather organically combines different layers with specific physical structures. By forming an innovative interface structure between the upper film composite component and the lower porous composite component, it successfully combines the elastic component with the breathable structure, overcoming the shortcomings of existing technologies that cannot effectively balance these two aspects of performance.

[0045] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
