Description

Technical Field

[0001] This utility model relates to an elastic webbing with ultraviolet light anti-counterfeiting function, belonging to the field of webbing production. Background Technology

[0002] Elastic webbing, as an accessory, has been widely used in textiles such as apparel, bags, and footwear. With the rapid development of the consumer market and the increasing demand for brand protection, elastic webbing anti-counterfeiting technology has become an indispensable and important link in the product supply chain, playing a particularly important role in product traceability and anti-counterfeiting verification.

[0003] However, traditional elastic webbing lacks effective anti-counterfeiting design, making it easy for products to be counterfeited. This causes significant problems and disputes for manufacturers, apparel brands, and consumers. Currently available anti-counterfeiting methods (such as printing ink, laser labels, and QR codes) are not only cumbersome and costly to implement on elastic webbing, but they also affect the overall aesthetics and comfort of the webbing. Furthermore, the anti-counterfeiting function is often compromised after repeated washing.

[0004] Therefore, there is an urgent need to develop a low-cost, high-efficiency elastic webbing with stable anti-counterfeiting function after multiple washes to meet the actual needs of apparel brands and consumers. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this utility model provides an elastic webbing with ultraviolet light anti-counterfeiting function. The technical solution of this utility model is as follows: An elastic webbing with ultraviolet anti-counterfeiting function includes a webbing body, which is integrally woven by a computerized jacquard weaving machine. The webbing body is made of interwoven warp and weft yarns. The warp yarns include fluorescent anti-counterfeiting yarn and non-fluorescent textile yarns that are the same color as the fluorescent anti-counterfeiting yarns under visible light. The fluorescent anti-counterfeiting yarns and the non-fluorescent textile yarns are interwoven through a structure set by a computerized jacquard program to form a hidden jacquard logo pattern.

[0006] Under natural light or ordinary white light, the appearance of the webbing body is dominated by the non-fluorescent textile yarn, and the jacquard logo pattern is not visible; under ultraviolet light, the fluorescent anti-counterfeiting yarn is excited to emit visible fluorescence, making the jacquard logo pattern visible.

[0007] The fluorescent anti-counterfeiting yarn is a yarn in which fluorescent rare earth materials are added to the spinning chips.

[0008] The warp yarns also include spandex-covered yarn and base pile yarn; the weft yarns are polyester low-elasticity yarns.

[0009] The spandex-covered yarn is woven in plain or modified plain weave to form the elastic skeleton of the webbing; the non-fluorescent textile yarn is woven in satin weave to form a smooth surface layer of the webbing; the fluorescent anti-counterfeiting yarn is controlled by a computer jacquard program to raise its warp heddles according to the shape of the logo pattern; the base pile yarn is woven in warp-compact plain or weft-compact plain weave to form a soft, skin-friendly layer of the webbing.

[0010] The weaving density of the webbing body is 13.0 to 17.0 stitches / cm.

[0011] The ribbon body is a colored woven ribbon made of colored yarn.

[0012] The webbing body has a single-layer structure or a multi-layer structure.

[0013] The jacquard logo pattern is a large jacquard logo pattern woven by a computer jacquard machine.

[0014] The advantages of this utility model are: Under normal natural light, the webbing appears as a comfortable, elastic webbing with a regular texture. However, when illuminated with ultraviolet (UV) light, the delicate logo pattern hidden within the elastic webbing becomes immediately and clearly visible, serving as an anti-counterfeiting measure. The webbing offers good overall comfort and aesthetics, effectively meeting consumers' high standards for comfort and appearance in apparel products and enhancing their overall quality.

[0018] The present invention will be further described below with reference to specific embodiments, and the advantages and features of the present invention will become clearer as a result of the description. However, these embodiments are merely exemplary and do not constitute any limitation on the scope of the present invention. Those skilled in the art should understand that modifications or substitutions can be made to the details and form of the technical solution of the present invention without departing from the spirit and scope of the present invention, but all such modifications and substitutions fall within the protection scope of the present invention.

[0019] See Figures 1 to 3This utility model relates to an elastic webbing with ultraviolet anti-counterfeiting function, comprising a webbing body 1, which is integrally woven by a computerized jacquard weaving machine. The webbing body 1 is composed of interwoven warp and weft yarns; the warp yarns include fluorescent anti-counterfeiting yarn and non-fluorescent textile yarns that are the same color as the fluorescent anti-counterfeiting yarn under visible light; the fluorescent anti-counterfeiting yarn and the non-fluorescent textile yarns are interwoven according to a structure set by a computerized jacquard program to jointly form a hidden jacquard logo pattern. The webbing body 1 is a yarn-dyed webbing woven with colored yarns. The webbing body 1 has a single-layer structure or a multi-layer structure.

[0020] Because the fluorescent anti-counterfeiting yarn and the non-fluorescent textile yarn have the same color under visible light, and are interwoven with a specific structure using computer jacquard technology, the jacquard logo pattern is completely hidden in the overall appearance of the webbing under normal lighting conditions and cannot be detected by the naked eye. This effectively avoids the impact of anti-counterfeiting marks on the aesthetics of the product, while also enhancing the concealment and surprise of anti-counterfeiting.

[0021] Under ultraviolet (UV) light of a specific wavelength, the rare-earth fluorescent material in the fluorescent anti-counterfeiting yarn is instantly excited, emitting bright visible fluorescence (such as red, green, yellow, and blue), thus clearly and conspicuously revealing the hidden logo pattern. The verification process is fast, simple, contactless, and the developing effect is obvious, making it difficult to counterfeit.

[0022] The fluorescent anti-counterfeiting yarn is made by adding fluorescent rare earth materials during the spinning and slicing stage. The fluorescent properties are an inherent property of the material, not a coating of finishing agents. Therefore, its anti-counterfeiting function has good water resistance, abrasion resistance, and weather resistance. Even after multiple washes and long-term use, the anti-counterfeiting effect will not weaken or fall off, solving the problem of easy wear and tear and peeling of traditional printing and labeling methods.

[0023] The webbing body retains the original softness, high elasticity, and breathability of elastic webbing. The soft, skin-friendly layer made of the base pile yarn enhances wearing comfort, while the elastic skeleton made of spandex-covered yarn ensures the webbing's resilience and durability.

[0024] This anti-counterfeiting webbing completes the weaving of all functional structures in one go during the weaving process, eliminating the need for subsequent secondary processing steps such as printing, hot stamping, and lamination. This simplifies the production process, improves production efficiency, and facilitates large-scale automated production, thereby reducing unit production costs.

[0025] Under natural light or ordinary white light, the appearance of the webbing body 1 is dominated by the non-fluorescent textile yarn, and the jacquard logo pattern is not visible; under ultraviolet light, the fluorescent anti-counterfeiting yarn is excited to emit visible fluorescence, making the jacquard logo pattern visible.

[0026] The fluorescent anti-counterfeiting yarn is a yarn in which fluorescent rare earth materials are added to the spinning chips.

[0027] The warp yarns also include spandex-covered yarn and base pile yarn; the weft yarns are polyester low-elasticity yarns.

[0028] The spandex-covered yarn 2 is woven in plain or modified plain weave to form the elastic skeleton of the webbing; the non-fluorescent textile yarn is woven in satin weave to form a smooth surface layer of the webbing; the fluorescent anti-counterfeiting yarn 1 is controlled by a computer jacquard program to raise its warp heddles according to the shape of the logo pattern; the base pile yarn 3 is woven in warp-compact plain or weft-compact plain weave to form a soft, skin-friendly layer of the webbing.

[0029] By assigning plain weave, satin weave, jacquard, and heavy plain weave structures to the spandex-covered yarn, non-fluorescent textile yarn, fluorescent anti-counterfeiting yarn, and base pile yarn respectively, the webbing achieves precise allocation and efficient synergy in four major functions: elastic support, smooth appearance, anti-counterfeiting visibility, and skin-friendly comfort. Each layer of yarn performs its own function, together forming a complete multi-functional system.

[0030] The fluorescent anti-counterfeiting yarn is independently controlled by a computer jacquard program to precisely weave according to the shape of the logo pattern, ensuring a clear outline. Simultaneously, it is embedded within a smooth surface layer formed by a satin weave, achieving extremely high concealment under normal conditions.

[0031] The satin weave of the outer layer provides a smooth and flat visual effect and feel; the heavy flat weave of the skin-contact layer creates a soft and rich velvet texture, avoiding the discomfort that may be caused by the spandex skeleton layer directly contacting the skin. The overall wearing experience is significantly better than that of webbing with anti-counterfeiting features added through post-processing.

[0032] The non-fluorescent textile yarn is made of one or more of polyester, nylon, cotton, or PP.

[0033] The weaving density of the webbing body 1 is 13.0 to 17.0 needles / cm.

[0034] The jacquard logo pattern is a large jacquard logo pattern woven by a computer jacquard machine.

[0035] The webbing of this invention is woven in an integrated manner using a computerized jacquard loom. The specific manufacturing process is as follows: 1. Preparation for warping: The process of arranging all warp yarns neatly as required and winding them onto the warp head. According to an embodiment, the warp system includes: Spandex-coated yarn with skeleton: provides core elasticity and is coated with a specific ratio and twist.

[0036] Non-fluorescent textile yarn (face yarn): constitutes the main body of the ribbon's appearance, and its color is consistent with that of the fluorescent anti-counterfeiting yarn.

[0037] Fluorescent anti-counterfeiting yarn: The core material for anti-counterfeiting function, fluorescent rare earth materials have been incorporated into it during the spinning and cutting process.

[0038] Base pile yarn: usually made of fine denier fiber (such as MICROFIBER nylon), used to form a soft, skin-friendly layer.

[0039] All warp yarns are prepared by the warping machine according to the preset type, number of yarns and arrangement order, and are ready to be woven.

[0040] 2. Threading heddles and reeds: Threading the heddle: The operator strictly follows the designed threading diagram, threading each warp yarn through the heddle eye in sequence. The heddle wires are mounted on the heddle frame, and their lifting and lowering movement will drive the warp yarns to form the shed.

[0041] Threading the reed: The warp yarns that have passed through the heddles are then threaded into the teeth of the reed in the order required by the reed insertion diagram. The function of the reed is to determine the width of the webbing (e.g., 25mm) and the warp density, and to tighten the weft yarns during beat-up.

[0042] 3. Programming and Weaving: Organizational Structure Design: In the MUCAD system of a computerized jacquard machine, different organizational patterns are designed according to the functional zones of the webbing: The spandex-covered yarn uses a plain weave structure with a tight structure to provide a stable elastic skeleton.

[0043] The non-fluorescent yarn uses a satin weave and has long floats to create a smooth, flat surface.

[0044] The fabric of the fluorescent anti-counterfeiting yarn is independently controlled by a computer jacquard program, which adjusts the rise and fall of each yarn in real time according to the shape of the logo pattern to weave the pattern.

[0045] The base pile yarn uses a flat weave, which causes the yarn to float on the reverse side of the webbing, creating a soft pile feel.

[0046] Weaving on the loom: Input the designed program (UPT format file) into the computerized jacquard loom. After the machine starts: The heald frame moves the warp yarns up and down according to the program instructions to form the shed.

[0047] A weft feeder (such as a weft hook) introduces the weft yarn (polyester low elasticity yarn) into the shed.

[0048] The reed swings forward, striking the weft yarn towards the weft end, where it interweaves with the warp yarn to form fabric.

[0049] The woven webbing is continuously pulled and wound up by take-up rollers, and the weaving density (e.g., 15.0 needles / cm) is controlled by adjusting the take-up speed.

[0050] 4. Post-processing: After weaving, the webbing is subjected to dry heat setting treatment as needed to stabilize its size, elasticity, and shape, ultimately producing the finished product.

[0051] The working principle of this utility model is as follows: 1. Covert mechanism (invisible under normal circumstances): Color matching: The key is that the fluorescent anti-counterfeiting yarn and the non-fluorescent textile yarn appear to be exactly the same color under visible light. This is the basis for achieving concealment.

[0052] Concealed Structure: Using computer jacquard technology, fluorescent anti-counterfeiting yarn is woven into a satin-textured surface layer composed of non-fluorescent yarns according to a specific organizational pattern. Under normal lighting, the human eye can only see the color and luster of the surface yarns and cannot distinguish the fluorescent anti-counterfeiting yarn of the same color embedded within, thus perfectly concealing the logo pattern.

[0053] 2. Developing mechanism (development under ultraviolet light): Photoluminescence: When the ribbon is irradiated with ultraviolet light (UV lamp) of a specific wavelength, the light energy is absorbed by the rare earth fluorescent material in the fluorescent anti-counterfeiting yarn, causing its atoms to transition to an excited state.

[0054] Energy release: Atoms in an excited state are unstable and will quickly transition back to the ground state, releasing the absorbed energy in the form of visible light. This phenomenon is called fluorescence. Therefore, fluorescent anti-counterfeiting yarn emits bright colors (such as red, green, blue, and yellow).

[0055] Pattern Presentation: At this point, only the fluorescent anti-counterfeiting yarn woven according to the preset logo pattern will emit light, while the surrounding non-fluorescent yarns remain unchanged. The contrast between light and dark makes the previously hidden pattern instantly clear, thus achieving the purpose of anti-counterfeiting verification. Once the ultraviolet light source is removed, the luminescence immediately stops, and the pattern disappears again.

[0056] 3. Durability mechanism (does not fail after washing): Material inherent properties: The fluorescent properties come from the rare earth materials added during the spinning stage. The fluorescent molecules have become part of the internal structure of the yarn, rather than a coating attached to the surface.

[0057] Stable physical properties: Therefore, this anti-counterfeiting function is not affected by physical actions such as washing and friction, and its lifespan is consistent with that of the webbing itself, solving the problem of easy wear and tear and detachment of traditional surface treatment anti-counterfeiting methods.

[0058] This invention uses an integrated weaving method to embed a fluorescent yarn into a regular yarn of the same color using a specific weave structure. Utilizing the difference in visual effects under visible and ultraviolet light, it achieves both everyday concealment and the ability to detect counterfeits. Simultaneously, its anti-counterfeiting performance is durable and long-lasting, without affecting the original elasticity and comfort of the webbing.

[0059] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
