Description

Technical Field

[0001] This utility model relates to the field of liquid cooling technology, specifically to a jacquard fabric. Background Technology

[0002] Jacquard fabric is a type of textile with unique textures and patterns. Its patterns are not formed through post-processing techniques such as printing or embroidery, but are directly woven during the weaving process through changes in the structure of the warp and weft yarns. Depending on the weaving method, jacquard fabrics can be divided into woven jacquard, warp-knitted jacquard, and weft-knitted jacquard. Weft-knitted jacquard fabrics typically exhibit better elasticity in both the horizontal and vertical directions, while warp-knitted and woven jacquard fabrics have relatively limited elasticity in these directions. Fine-check jacquard fabric, as a type of jacquard fabric, features a unique, dense check pattern created by interlacing warp and weft yarns according to a predetermined large jacquard weave pattern. The yarn count is fine, requiring high-quality raw materials. However, in practical applications, existing fine-check jacquard fabrics, while possessing advantages in aesthetics and unique texture, still have shortcomings in structural stability and durability. Specifically, when these jacquard fabrics are subjected to snagging, friction, or other forms of physical damage during use, once a local yarn breaks or shifts, the damage point tends to expand easily. Especially when pulling on a single yarn in a damaged area, the yarn can easily continue to come loose, leading to a disarray in the overall fabric structure. This phenomenon not only affects the fabric's appearance but, more importantly, weakens its overall bonding performance and structural integrity, thus significantly reducing the fabric's actual lifespan and application value. 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 jacquard fabric that can improve the overall connection performance and structural integrity of the jacquard fabric after it has been physically damaged.

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

[0005] Technical Solution 1: A jacquard fabric, comprising a fabric body formed by interlacing warp and weft yarns, the fabric body comprising: a core yarn layer; at least one set of outer warp yarns, the outer warp yarns being arranged around the core yarn layer and interlacing with the core yarn layer; at least one set of outer weft yarns, the outer weft yarns being arranged around the core yarn layer and interlacing with the core yarn layer and the outer warp yarns; and a plurality of end fixing sleeves, the inner cavity of each end fixing sleeve respectively accommodating and binding at least one end of the outer warp yarn and / or at least one end of the outer weft yarn.

[0006] Technical Solution 2 based on Technical Solution 1: The plurality of end fixing sleeves are arranged in an array or linear arrangement along the edge or predetermined area of ​​the main body of the fabric.

[0007] Technical solution three, based on technical solution one or two: Each of the aforementioned end fixing sleeves is a tubular body with a predetermined inner cavity profile and wall thickness.

[0008] Technical Solution 4 based on Technical Solution 1: The main body of the fabric is further provided with an edge reinforcement strip on its outer periphery, and the edge reinforcement strip is connected to at least a portion of the plurality of end fixing sleeves.

[0009] Technical Solution 5 based on Technical Solution 1: The at least one set of outer weft yarns includes a first outer weft yarn group and a second outer weft yarn group, the two sets of weft yarns being symmetrically or alternately arranged relative to the core yarn layer; and / or, the at least one set of outer warp yarns includes a first outer warp yarn group and a second outer warp yarn group, the two sets of warp yarns being interwoven with the outer weft yarn group according to a predetermined weaving pattern.

[0010] Technical Solution Six based on Technical Solution Five: At least part of the yarns in the first outer weft yarn group, the second outer weft yarn group, the first outer warp yarn group, and the second outer warp yarn group are composite yarns, and each composite yarn includes a core yarn and at least one outer covering layer covering the core yarn.

[0011] Technical solution seven based on technical solution six: the core yarn of the composite yarn is made of conductive fiber material, and the outer covering layer is made of cotton fiber material or chemical fiber material.

[0012] Technical solution eight based on technical solution one: The core yarn layer is composed of one or more parallel yarns, or is composed of a pre-formed yarn sheet with mesh pores.

[0013] Technical solution nine based on technical solution three: The tubular body is composed of at least one of thermoplastic polymer, thermosetting resin or metal material.

[0014] Technical solution ten based on technical solution four: The edge reinforcing strip is a strip-shaped woven or non-woven fabric with a predetermined thickness and width, which is fixedly connected to at least a portion of the plurality of end fixing sleeves through stitches, adhesive layers or partial heat-fused connections.

[0015] 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:

[0016] Technical Solution 1 provides a jacquard fabric that improves overall connectivity and structural integrity after physical damage. The core yarn layer in the fabric body forms the foundation of the entire fabric, providing a relatively stable reference level for the arrangement and interweaving of the outer yarns. The outer warp and weft yarns, arranged and interwoven around this core yarn layer, construct the basic shape and initial integrity of the fabric through their interlacing points, which transmit and distribute stress between the yarns. Furthermore, the inner cavity of each end-fixing sleeve accommodates and binds the end of the outer warp or weft yarn. This design effectively anchors the yarn ends. When the fabric is subjected to external pulling forces or suffers damage such as snagging or yarn breakage, the yarn ends, due to the physical constraint of the end-fixing sleeves, cannot easily slip out of the fabric structure or be further pulled out. This end-anchoring mechanism works synergistically with the interlacing structure between the yarns: the interlacing first bears and distributes some of the stress, while the end-fixing sleeves provide restraint at the ends where the yarns are most prone to unraveling. In traditional fabrics, once the yarn ends become unsupported, localized damage can easily escalate due to a chain reaction, leading to widespread fraying and structural disarray. However, in this solution, because the yarn ends are fixed, even if a yarn breaks, the broken end is confined to the vicinity of the fixing sleeve, preventing adjacent yarns from easily loosening or coming loose. This effectively controls localized damage within a smaller area, maintaining the overall connectivity and structural integrity of the fabric, thereby extending its actual service life.

[0017] In technical solution two, the arrangement of multiple end-fixing sleeves is limited to an array or linear arrangement along the edge of the fabric body or a predetermined area. This regular arrangement makes the constraint of the yarn ends by the end-fixing sleeves more uniform and comprehensive. For example, when the end-fixing sleeves are set along the edge of the fabric, the weakest and most easily worn edge areas of the fabric can be directly reinforced, improving the durability of the edges. If the end-fixing sleeves are arranged along specific areas inside the fabric body, such as the outline of the pattern or areas that are frequently subjected to stress, targeted reinforcement can be achieved for these critical areas, preventing structural damage caused by stress concentration.

[0018] In technical solution three, the shape of each end-fixing sleeve is further defined as a tubular body with a predetermined inner cavity contour and wall thickness. The tubular end-fixing sleeve structure ensures that the end-fixing sleeve can stably and effectively accommodate and restrain the yarn end. The predetermined inner cavity contour can be adapted according to the thickness and quantity of the fixed yarn to achieve a tight fit to the yarn end, reducing unnecessary yarn movement within the sleeve and thus providing reliable fixation. Simultaneously, the predetermined wall thickness of the tubular body ensures its mechanical strength and rigidity, making it less prone to significant deformation or damage when subjected to yarn tension or external physical forces, ensuring the long-term effectiveness and reliability of the end-fixing function.

[0019] Technical solution four adds a feature where the fabric body has edge-reinforcing strips along its outer periphery, and these strips are connected to at least a portion of multiple end-fixing sleeves. The edge-reinforcing strips provide additional structural support to the fabric's edge area. Working in conjunction with the end-fixing sleeves, they enhance the overall strength and tear resistance of the fabric edges. The end-fixing sleeves primarily lock the ends of the yarns constituting the fabric body, preventing them from slipping off the edges; while the edge-reinforcing strips connect these fixed points or areas, forming a more continuous and robust edge protection system. This system can more effectively distribute and withstand tensile, frictional, and other external forces applied to the fabric edges. This combined structure not only further reduces wear and damage to the fabric edges but also improves the overall durability and appearance retention of the fabric.

[0020] Technical Solution Five further specifies the specific configuration of the outer weft yarn group and the outer warp yarn group. For example, the two weft yarn groups can be symmetrically or alternately configured relative to the core yarn layer, and the two warp yarn groups can be interwoven with the weft yarn group according to a predetermined weave pattern. The symmetrical or alternately configured yarn groups allow the fabric to exhibit more balanced mechanical properties in different directions, reducing the possibility of stress concentration. Interweaving according to a predetermined weave pattern ensures a sufficient number and reasonable distribution of bonding points between the yarns, thereby improving the overall strength and deformation resistance of the fabric. Furthermore, the above-mentioned specific configuration, in conjunction with the end fixing sleeves, allows the end fixing sleeves to anchor the yarn ends, better maintaining the integrity of this optimized structure. Therefore, the fabric exhibits better structural stability and durability when subjected to external forces.

[0021] In technical solution six, at least a portion of the yarns constituting the outer warp and weft yarn group is defined as composite yarn, and each composite yarn includes a core yarn and at least one outer covering layer covering the core yarn. Using a composite yarn structure allows the yarns constituting the main body of the fabric to possess superior overall physical properties. The core yarn can be made of materials with high strength, high modulus, or other specific properties to primarily bear mechanical loads or achieve predetermined functions. The outer covering layer can be made of abrasion-resistant, soft, or specific hand-feeling materials to improve the surface characteristics and durability of the yarn and the final fabric. When the ends of these inherently enhanced composite yarns are secured with end-fixing sleeves, not only are the strength and durability of the yarn itself effectively utilized, but the stability of its ends is also ensured.

[0022] Technical Solution Seven specifically defines the material composition of the composite yarn: the core yarn is made of conductive fiber material, while the outer covering layer is made of cotton fiber material or chemical fiber material. This specific material combination allows the jacquard fabric to effectively integrate antistatic function while maintaining its basic properties as a textile. The core yarn, made of conductive fiber material, provides an effective path for the conduction and dissipation of static charge within the fabric. This significantly reduces or eliminates the accumulation of static electricity caused by friction, thereby improving comfort during wear or use and avoiding inconvenience caused by static electricity attracting dust. The outer covering layer, made of cotton fiber or chemical fiber material, ensures that the fabric has good hand feel, breathability (like the characteristics of cotton fiber) or easy care properties (like the characteristics of some chemical fibers), and can also provide a certain degree of physical protection for the internal conductive core yarn, helping to extend the effective life of its conductive function.

[0023] Technical Solution 8 further clarifies the specific structure of the core yarn layer, which consists of one or more parallel yarns, or a pre-formed yarn sheet with a grid-like structure. For example, the core yarn layer is composed of parallel yarns, and their uniform arrangement helps the outer yarns form an orderly and evenly stressed interlacing structure on it. When the core yarn layer is a yarn sheet with a grid-like structure, its planar stability and the pre-formed grid structure can more effectively guide and support the positioning of the outer yarns, contributing to the formation of a fabric body with a more uniform structure and more stable dimensions.

[0024] In technical solution nine, the tubular body constituting the end-fixing sleeve is specified to be made of at least one of thermoplastic polymers, thermosetting resins, or metal materials. This specific limitation on the tubular material ensures that the end-fixing sleeve itself possesses sufficient physical properties to fulfill its function. Thermoplastic polymers typically offer ease of processing and molding, relatively low cost, and a certain degree of toughness. Thermosetting resins generally possess high strength, hardness, and good heat resistance. Metal materials provide excellent strength, abrasion resistance, and rigidity. Depending on the end application of the fabric and the performance requirements of the end-fixing sleeve, selecting one or more of these materials ensures that the end-fixing sleeve is not easily damaged or deformed during long-term use, and can continuously and effectively bind the yarn ends, thereby guaranteeing the long-term maintenance of the overall fabric structural stability.

[0025] Technical Solution Ten further refines the structure of the edge reinforcement strip and its connection method with the end retaining sleeves. The edge reinforcement strip is specified as a strip of woven or non-woven fabric with a predetermined thickness and width, and it is clearly defined that it is fixedly connected to at least a portion of multiple end retaining sleeves through stitches, adhesive layers, or partial heat-fused connections, ensuring the reliability and effectiveness of the edge reinforcement measures. The predetermined thickness and width provide the strip with sufficient strength and coverage area to effectively protect the fabric edges. The defined connection method, such as stitching, bonding, or heat fusion, provides a strong bond, allowing the edge reinforcement strip and end retaining sleeves to form a stable whole.

[0050] Example

[0051] This embodiment relates to a jacquard fabric, see reference Figures 1 to 3 The jacquard fabric includes a fabric body 1 formed by interlacing warp and weft yarns. The fabric body 1 includes a core yarn layer 4, with at least one set of outer warp yarns arranged around and interlaced with the core yarn layer 4, and at least one set of outer weft yarns arranged around and interlaced with both the core yarn layer 4 and the outer warp yarns. Furthermore, the fabric body 1 also includes a plurality of end-fixing sleeves 3, the inner cavity of each end-fixing sleeve 3 respectively accommodating and binding at least one end of the outer warp yarn and / or at least one end of the outer weft yarn.

[0052] Specifically, refer to Figure 2 and Figure 3 The main body of the fabric 1 includes a core yarn layer 4 located in the central region. This core yarn layer 4 can be composed of one or more parallel yarns, such as ordinary cotton yarn or polyester filament, introduced parallel to each other during weaving as a base layer. Alternatively, the core yarn layer 4 can be a pre-formed yarn sheet with a mesh-like structure, such as a lightweight leno fabric, knitted mesh fabric, or a mesh film with a certain elasticity made from thermoplastic polymers such as polyurethane (TPU) through specific processes (such as meltblown nonwoven followed by hot pressing, film extrusion followed by perforation, or biaxial stretching to create perforations). This yarn sheet with a mesh-like structure allows the outer warp and weft yarns to partially embed or pass through during weaving, thus forming a tighter bond with the core yarn layer 4. Simultaneously, its planar stability and elasticity provide good skeletal support and a certain degree of resilience for the entire fabric.

[0053] Around the core yarn layer 4, at least one set of outer warp yarns and at least one set of outer weft yarns are arranged. Specifically, the outer weft yarns may include a first set of outer weft yarns 5 and a second set of outer weft yarns 6. These two sets of weft yarns can be arranged symmetrically with respect to the core yarn layer 4, i.e., one set is located on one side (e.g., above) of the core yarn layer 4, and the other set is located on the other side (e.g., below) of the core yarn layer 4, or they can be arranged alternately around the core yarn layer 4 on the same layer. Similarly, the outer warp yarns may also include a first set of outer warp yarns 7 and a second set of outer warp yarns 8. These outer warp yarns and outer weft yarns are interwoven with the core yarn layer 4 and with each other through specific jacquard weave patterns (e.g., plain weave, twill weave, satin weave, or more complex multi-layer weaves, combined weaves, etc.) to form the desired fine check or other jacquard patterns on the fabric surface.

[0054] Furthermore, at least a portion of these outer warp and weft yarns can employ a composite yarn structure. (See reference...) Figure 4 A schematic diagram of a typical composite yarn cross-section is shown, which includes a core yarn 9 located at the center and at least one outer covering layer disposed around the core yarn 9. Figure 4In this composite yarn, the outer covering layer is composed of a first covering yarn 10 and a second covering yarn 11. This composite yarn can be prepared using various spinning processes, such as core-spun spinning or cover spinning. To impart good antistatic properties to the jacquard fabric, the core yarn 9 is preferably made of conductive fiber materials, such as stainless steel fiber, carbon fiber, chemical fibers with a metal-plated surface, or inherently conductive polymer fibers. The outer covering layer is preferably made of cotton fiber materials to ensure the fabric's soft feel, moisture absorption, breathability, and skin-friendliness; of course, the outer covering layer can also be made of chemical fiber materials such as polyester fiber, nylon fiber, or blended yarns of these chemical fibers and cotton fibers to adjust other properties such as fabric strength and abrasion resistance. For example, a specific composite yarn could be: the core yarn 9 is a 20-micron diameter stainless steel filament, and the outer layer is double-wrapped with two strands of 32-count combed cotton yarn with opposite twist directions.

[0055] Multiple end fixing sleeves 3 are provided at the edges of the main fabric 1, especially at the ends of the outer warp and weft yarns. For example... Figure 3 As shown, the inner cavity of each end-fixing sleeve 3 is designed to accommodate and effectively bind the ends of these outer yarns. This binding can be achieved in various ways, for example, by having the inner diameter of the end-fixing sleeve 3 itself fit tightly with the outer diameter of the yarn end; or by locally heating the end-fixing sleeve 3 (if it is made of heat-shrinkable material) after the yarn end is inserted into the end-fixing sleeve 3 to shrink and tighten it around the yarn end; or by applying a small amount of adhesive to the yarn end before inserting it into the end-fixing sleeve 3. These end-fixing sleeves 3 are preferably arranged linearly and continuously or intermittently along the left and right edges of the fabric body 1. As another embodiment, if specific internal areas of the fabric also require enhanced structural stability, the end-fixing sleeves 3 can also be arranged in an array or a specific curved trajectory in these predetermined areas.

[0056] Each end-fixing sleeve 3 is tubular. The length of this tubular body is typically between 2 mm and 10 mm, and the wall thickness is typically between 0.1 mm and 1 mm. The inner contour of the tubular body can be circular, elliptical, flat, or square, to accommodate the cross-sectional shape of the yarn or yarn bundle being fixed. These tubular bodies can be made of at least one of thermoplastic polymers (such as polyethylene, polypropylene, nylon), thermosetting resins (such as epoxy resin), or metallic materials (such as aluminum, copper). For example, using thermoplastic polymers, tubular end-fixing sleeves 3 can be pre-formed using injection molding or extrusion processes, and then tightened by heating to shrink them; using thermosetting resins, liquid resin can be impregnated or dripped onto the yarn end and then cured; using metallic materials, small metal tubes or metal clamps can be made to mechanically press and fix the yarn end.

[0057] To further enhance the edge strength and durability of the fabric, refer to Figure 1 and Figure 2 The fabric body 1 has an edge reinforcement strip 2 along its outer periphery, particularly in the edge area where the end fixing sleeves 3 are located. This edge reinforcement strip 2 can be a strip of woven fabric (e.g., made of high-strength chemical fibers such as polyester and nylon) or nonwoven fabric (e.g., made of fibers such as polypropylene and polyester through needle punching, hydroentangling, or thermal bonding processes) with a thickness typically ranging from 0.3 mm to 1.5 mm and a width typically ranging from 8 mm to 25 mm. This edge reinforcement strip 2 forms a synergistically reinforced edge structure by connecting to multiple end fixing sleeves 3 (or at least a portion thereof) at the fabric edge. The connection method can be varied; for example, the edge reinforcement strip 2 can be sewn to the fabric edge using high-strength sewing thread; a hot melt adhesive film or liquid adhesive can be applied between the edge reinforcement strip 2 and the fabric edge, achieving a strong bond through hot pressing or room temperature curing; if both the edge reinforcement strip 2 and the end fixing sleeves 3 (or the yarn near them) are thermoplastic materials, an integrated connection can also be achieved using high-frequency welding or ultrasonic welding.

[0058] This embodiment relates to a jacquard fabric, wherein the core yarn layer 4 in the main body of the fabric 1 lays the foundation for the entire fabric, providing a relatively stable reference layer for the arrangement and interweaving of the outer yarns. The outer warp and weft yarns, arranged and interwoven around and with this core yarn layer 4, construct the basic shape and initial integrity of the fabric through their interlacing points, which transmit and distribute stress between the yarns. Based on this, the inner cavity of each end-fixing sleeve 3 accommodates and binds the end of the outer warp or weft yarn. This design effectively anchors the yarn ends. When the fabric is subjected to external pulling forces or suffers damage such as snagging or yarn breakage, the yarn ends, due to the physical constraint of the end-fixing sleeves 3, cannot easily slip off from the fabric structure or be further pulled out. This end-anchoring mechanism works synergistically with the interlacing structure between the yarns: the yarn interlacing first bears and disperses some of the stress, while the end-fixing sleeves 3 provide restraint at the ends where the yarns are most prone to unraveling. In traditional fabrics, once the yarn ends become unsupported, localized damage can easily escalate due to a chain reaction, leading to widespread fraying and structural disarray. However, in this solution, because the yarn ends are fixed, even if a yarn breaks, the broken end is confined to the vicinity of the fixing sleeve, preventing adjacent yarns from easily loosening or coming loose. This effectively controls localized damage within a smaller area, maintaining the overall connectivity and structural integrity of the fabric, thereby extending its actual service life.

[0059] 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.
