Description

Technical Field

[0001] This application belongs to the field of textile technology, specifically relating to color-blocking jacquard webbing and its preparation method. Background Technology

[0002] Jacquard webbing is commonly used to decorate textiles and garments. As an important textile decorative material, jacquard webbing is widely used in the decoration and functional components of clothing, bags, shoes, and hats. With consumers' increasing demands for product appearance quality, the color expressiveness and aesthetics of jacquard webbing have become crucial factors influencing product quality.

[0003] Conventional jacquard weave tape suffers from color variations due to the interplay of different colors, resulting in a less than ideal color in the finished tape and affecting its overall appearance. Traditional methods to improve color transparency in jacquard weave tape include increasing warp density, using different yarn thicknesses, and altering the weave structure. However, these methods have limitations and cannot fundamentally solve the color transparency problem.

[0004] When jacquard weaves are made by interweaving light and dark colored yarns, the lighter yarns lose their original color due to the influence of the darker yarns. This color seepage problem severely affects the color expression and aesthetics of the weave. Traditional methods to prevent color seepage, such as increasing density, can lead to yarn pilling and skipped yarns on the weave surface. Adjusting the yarn thickness still results in color seepage, and changing the weave structure can easily cause pilling and snagging. None of these methods can fundamentally eliminate the color seepage problem. Summary of the Invention

[0005] Based on this, one embodiment of this application provides a color-blocking jacquard webbing and a method for preparing the same.

[0006] This application provides a color-blocking jacquard webbing, which includes interwoven warp and weft yarns;

[0007] The warp yarns include an upper layer warp yarn, a lower layer warp yarn, and an isolation layer warp yarn; the isolation layer warp yarn is disposed between the upper layer warp yarn and the lower layer warp yarn, and the colors of the upper layer warp yarn and the lower layer warp yarn are isolated by the isolation layer warp yarn so that the colors of the upper layer warp yarn and the lower layer warp yarn do not affect each other;

[0008] The weft yarn includes an upper weft yarn and a lower weft yarn; the upper weft yarn is interwoven with the upper warp yarn and the isolation layer warp yarn, and the lower weft yarn is interwoven with the lower warp yarn and the isolation layer warp yarn.

[0009] In some embodiments, the upper warp yarn and the insulating layer warp yarn are both the color of the jacquard base color, and the lower warp yarn is the color of the jacquard pattern.

[0010] In some embodiments, the density of the warp yarns is 60 yarns / cm to 200 yarns / cm.

[0011] In some embodiments, the density of the weft yarn is 10 yarns / cm to 60 yarns / cm.

[0012] In some embodiments, the color-blocking jacquard weave is woven with a high-medium-low opening structure, so that the warp yarns can interweave at least three interlacing points.

[0013] In some embodiments, the weave structure of the isolation layer warp yarns of the anti-seepage jacquard webbing is at least one of the following: high-low structure, medium-high-low structure, three-medium-one-high structure, and three-medium-one-low structure.

[0014] In some embodiments, both the warp and weft yarns are made of high F-count yarns.

[0015] In some embodiments, the F-number specification yarn includes nylon yarn or polyester yarn.

[0016] In some embodiments, the nylon yarn has an F number ≥ 48F; the polyester yarn has an F number ≥ 36F.

[0017] In some embodiments, the materials of the upper warp yarn, the lower warp yarn, the insulating layer warp yarn, the upper weft yarn, and the lower weft yarn are each independently selected from one or more of cotton, linen, silk, wool, polyester fiber, nylon, and polyacrylonitrile fiber.

[0018] This application also provides a method for preparing the aforementioned color-blocking jacquard webbing, comprising the following steps:

[0019] It provides upper warp yarns, insulating layer warp yarns, and lower warp yarns;

[0020] The upper, lower, and higher opening head devices are used to interweave the upper warp yarns, the isolation layer warp yarns, and the lower warp yarns, forming at least three interweaving points. The upper and lower weft yarns are simultaneously fed using double weft needles, with the upper weft yarns interweaving with the upper warp yarns and the isolation layer warp yarns, and the lower weft yarns interweaving with the lower warp yarns and the isolation layer warp yarns, forming the color-blocking jacquard weave. The isolation layer warp yarns isolate the colors of the upper and lower weft yarns.

[0021] In some embodiments, the density of the upper warp, the insulating layer warp, and the lower warp is each independently 60-200 threads / cm.

[0022] In some embodiments, the density of the upper weft yarn and the lower weft yarn is independently 10 yarns / cm to 60 yarns / cm.

[0023] In some embodiments, the preparation method further includes a post-treatment step;

[0024] The post-processing steps include: pre-shrinking using a hot iron at a temperature of 100℃-150℃ and a speed of 7 r / min-8 r / min.

This application, through its three-layer structure design and isolation layer technology, effectively solves the color-transmitting problem caused by the mutual influence of light and dark colored yarns in traditional jacquard webbing, resulting in a webbing color that better conforms to standard colors and is cleaner and more aesthetically pleasing. The isolation layer in the three-layer structure effectively blocks the mutual penetration of colors between the upper and lower warp layers, fundamentally solving the color-transmitting problem.

[0030] The present application will be further described in detail below with reference to the embodiments and examples. It should be understood that these embodiments and examples are for illustrative purposes only and are not intended to limit the scope of the present application. The purpose of providing these embodiments and examples is to enable a more thorough and comprehensive understanding of the disclosure of the present application. It should also be understood that the present application can be implemented in many different forms and is not limited to the embodiments and examples described herein. Those skilled in the art can make various modifications or alterations without departing from the spirit of the present application, and the equivalent forms obtained also fall within the protection scope of the present application. Furthermore, numerous specific details are set forth in the following description to provide a fuller understanding of the present application. It should be understood that the present application can be implemented without one or more of these details.

[0031] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0032] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0033] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0034] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0036] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element present. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not indicate the only possible implementation. In this application, "optionally," "optionally," and "optional" mean that they are optional, that is, they are selected from either "present" or "absent." If multiple "optional" statements appear in a technical solution, unless otherwise specified and there are no contradictions or mutual constraints, each "optional" statement is independent.

[0037] The term "three-layer structure" refers to a fabric structure with three layers—upper, middle, and lower—formed during the weaving process. In this field, the three-layer structure is achieved through a special weaving technique, where the upper warp yarns form the surface layer of the weave, the lower warp yarns form the bottom layer, and the middle yarns act as an insulating layer connecting the upper and lower layers. This structure enhances fabric strength, improves appearance, and enables special functions in the textile industry. Specifically, in this application, the main function of the three-layer structure is to isolate the colors of the upper and lower layers through the insulating layer, preventing color bleeding.

[0038] The term "intermediate layer warp" refers to the intermediate layer of yarn placed between the upper and lower warp yarns of a webbing. Its main function is to connect the upper and lower layers and provide insulation. In textile weaving, the intermediate layer warp is usually the same or similar in color to the upper warp yarn to ensure a consistent appearance. The weave structure of the intermediate layer warp can take various forms, such as high-low, medium-high-low, and three-medium-one-high / three-medium-one-low structures, etc. These structures effectively achieve the color isolation function.

[0039] The term "double-weft weaving" refers to a special weaving technique developed from traditional single-weft weaving. In single-weft weaving, one weft needle interweaves with the upper and lower warp yarns to form the fabric; while in double-weft weaving, two weft needles, namely the upper weft needle and the lower weft needle, interweave with the upper and lower warp yarns respectively to form the fabric. Alternatively, the upper weft needle can interweave with the lower warp yarn, and the lower weft needle can interweave with the upper warp yarn. This weaving method enables the effective construction of multi-layer structures and is one of the key processes for achieving the three-layer structure's colorfastness in this application.

[0040] The term "high-medium-low shedding structure" refers to a weaving structure in jacquard weaving equipment where the shedding of the hermite fibers can form a weaving structure with three different positions: high, medium, and low. Traditional jacquard equipment typically uses a high-low shedding structure, which can only form two interlacing points; while the high-medium-low shedding structure can form three interlacing points, making the fabric structure more complex and three-dimensional. In this application, the high-medium-low shedding structure is an important equipment condition for realizing three-layer weaving, which can enhance the isolation effect of the separating layer.

[0041] The term "F-count yarn" refers to yarn fineness and bulkiness, a technical parameter used in the textile industry. A higher F-count indicates better bulkiness and covering power. In this field, high-F-count yarn typically refers to specialty yarns with an F-count 2-3 times that of ordinary yarns, offering superior coverage and softness. Using high-F-count yarns effectively improves the colorfastness of webbing, resulting in a smoother, more even surface and purer colors.

[0042] This application provides a color-blocking jacquard webbing, which includes interwoven warp and weft yarns;

[0043] The warp yarns include an upper layer warp yarn, a lower layer warp yarn, and an isolation layer warp yarn; the isolation layer warp yarn is disposed between the upper layer warp yarn and the lower layer warp yarn, and the colors of the upper layer warp yarn and the lower layer warp yarn are isolated by the isolation layer warp yarn so that the colors of the upper layer warp yarn and the lower layer warp yarn do not affect each other;

[0044] The weft yarn includes an upper weft yarn and a lower weft yarn; the upper weft yarn is interwoven with the upper warp yarn and the isolation layer warp yarn, and the lower weft yarn is interwoven with the lower warp yarn and the isolation layer warp yarn.

[0045] This application effectively solves the color seepage problem caused by the mutual influence of light and dark colored yarns in traditional jacquard webbing through a three-layer structure design and isolation layer technology. This makes the webbing color more consistent with standard colors and cleaner, more aesthetically pleasing. The isolation layer in the three-layer structure effectively prevents the colors of the upper and lower warp yarns from penetrating each other, fundamentally solving the color seepage problem.

[0046] In some embodiments, the upper warp yarn and the insulating layer warp yarn are both the color of the jacquard base color, and the lower warp yarn is the color of the jacquard pattern.

[0047] This color scheme ensures the purity of the base color and the vibrancy of the pattern colors, enhancing the visual appeal of the webbing. Specifically, the upper warp and the outer layer warp can be made of light-colored yarns such as white or light gray, while the lower warp can be made of dark-colored yarns such as black or dark blue, creating a striking color contrast.

[0048] In some embodiments, the density of the warp yarns is 60 yarns / cm to 200 yarns / cm.

[0049] In some embodiments, the density of the weft yarn is 10 yarns / cm to 60 yarns / cm.

[0050] Specifically, the warp density can be selected from any value among 60 threads / cm, 80 threads / cm, 100 threads / cm, 120 threads / cm, 140 threads / cm, 160 threads / cm, 180 threads / cm, and 200 threads / cm; the weft density can be selected from any value among 10 threads / cm, 20 threads / cm, 30 threads / cm, 40 threads / cm, 50 threads / cm, and 60 threads / cm. A reasonable density configuration ensures the tightness and strength of the webbing.

[0051] In some embodiments, the color-blocking jacquard weave employs a high-medium-low opening structure, allowing the warp yarns to interweave at least three interlacing points. This high-medium-low opening structure creates a more complex three-dimensional structure, enhancing the isolation effect of the insulating layer. Specifically, the high-medium-low opening structure can be achieved using a high-medium-low opening head-operated machine, such as a high-medium-low opening jacquard head-operated machine.

[0052] In some embodiments, the isolation layer of the anti-seepage jacquard webbing has an organizational structure of at least one of the following: high-low structure, medium-high-low structure, three-medium-one-high structure, and three-medium-one-low structure.

[0053] In some embodiments, both the warp and weft yarns are high-filament (F) yarns. Specifically, the high-filament yarn can be 2-3 times the F number of ordinary yarns, such as 40D / 2 nylon yarn or 75D / 1 polyester yarn.

[0054] In some embodiments, the F-number specification yarn includes nylon yarn or polyester yarn.

[0055] In some embodiments, the nylon yarn has an F number ≥ 48F; the polyester yarn has an F number ≥ 36F.

[0056] In some embodiments, the materials of the upper warp yarn, the lower warp yarn, the insulating layer warp yarn, the upper weft yarn, and the lower weft yarn are each independently selected from one or more of cotton, linen, silk, wool, polyester fiber, nylon, and polyacrylonitrile fiber.

[0057] This application also provides a method for preparing the aforementioned color-blocking jacquard webbing, comprising the following steps:

[0058] It provides upper warp yarns, insulating layer warp yarns, and lower warp yarns;

[0059] Using a high, medium, and low opening head device, the upper warp yarn, the insulating layer warp yarn, and the lower warp yarn are interwoven to form at least three interlacing points; and

[0060] The upper and lower weft yarns are fed simultaneously using double weft needles. The upper weft yarns interweave with the upper warp yarns and the isolation layer warp yarns, and the lower weft yarns interweave with the lower warp yarns and the isolation layer warp yarns to form the color-blocking jacquard weave. The isolation layer warp yarns isolate the colors of the upper and lower weft yarns.

[0061] This application employs a double-weft weaving method, where the upper weft needles interweave with the upper warp yarns, and the lower weft needles interweave with the lower warp yarns, thus achieving an effective three-layer structure and enhancing the webbing's colorfastness.

[0062] In some embodiments, the density of the upper warp, the insulating layer warp, and the lower warp is each independently 60-200 threads / cm.

[0063] In some embodiments, the density of the upper weft yarn and the lower weft yarn are each independently between 10 yarns / cm and 60 yarns / cm. Specifically, the warp density can be selected from any value among 60 yarns / cm, 80 yarns / cm, 100 yarns / cm, 120 yarns / cm, 140 yarns / cm, 160 yarns / cm, 180 yarns / cm, and 200 yarns / cm; the weft density can be selected from any value among 10 yarns / cm, 20 yarns / cm, 30 yarns / cm, 40 yarns / cm, 50 yarns / cm, and 60 yarns / cm.

[0064] In some embodiments, a post-processing step is also included.

[0065] In some embodiments, the finishing step includes: pre-shrinking using a heat press at a temperature of 100℃-150℃ and a speed of 7 r / min-8 r / min. This finishing process stabilizes the webbing structure and improves product quality. Specifically, the heat press temperature can be selected from any value among 100℃, 110℃, 120℃, 130℃, 140℃, and 150℃.

[0066] In some embodiments, the ratio of light-colored yarn to dark-colored yarn used in the manufacturing process is 2:1. A reasonable yarn ratio configuration optimizes the colorfastness. Specifically, the light-colored yarn can be white nylon yarn, spandex, etc., and the dark-colored yarn can be black polyester yarn, etc.
