Abstract
Description
Technical Field
[0001] This invention relates to an integrated spraying and printing weaving system and process, belonging to the field of textile weaving. Background Technology
[0002] With the rapid development of the textile industry, consumers have increasingly higher demands for the aesthetics and functionality of fabrics. Traditional fabric dyeing methods, such as immersion dyeing and spray dyeing, while achieving color changes, often involve complex processes, high costs, and environmental impacts. Furthermore, these traditional methods may also affect the fabric's hand feel and durability.
[0003] While weft knitting offers high production speed and flexibility, it still has limitations in color processing. Traditional weft knitting techniques can mostly only produce products with a single color or simple patterns. To achieve more complex designs or color gradient effects, additional dyeing or printing processes are required after weaving. This not only increases production costs and complexity but can also lead to problems such as uneven dyeing.
[0004] To simplify production processes and reduce environmental pollution, the textile industry has been seeking methods to achieve color changes directly during weaving. For example, inkjet printing disperses pigment into tiny droplets using a spray gun or atomizer, uniformly spraying them onto the material surface to achieve a gradient effect from one color to another. However, this method is not only labor-intensive and resource-intensive but can also lead to environmental pollution and increased costs. On the other hand, while jacquard weaving can create gradient effects on fabrics through combinations of different yarns and stitch patterns, its drawing efficiency is low, requiring extensive manual drawing, which prolongs the production cycle, and the jacquard effect appears unnatural upon close inspection.
[0005] In recent years, with the development of digital inkjet printing technology, its application in the textile industry has become increasingly widespread. The advantages of digital inkjet printing technology lie in its ability to achieve highly customized pattern designs and the quick change of different patterns, greatly improving production flexibility. However, current inkjet printing technology is mainly applied to finished fabrics, with relatively little research on direct color processing during online production.
[0006] Furthermore, the post-dyeing treatment of yarn is also a crucial step. In traditional dyeing processes, the yarn's tension and crimp can change due to variations in moisture levels after dyeing, necessitating re-warping to restore tension consistency and morphological stability. This process not only increases production steps but can also potentially affect the quality of the final product.
[0007] To overcome these problems, researchers began exploring methods to integrate dyeing functions into weft knitting machines. Currently, some research focuses on how to place inkjet devices at different locations on the weft knitting machine to achieve online dyeing. However, these methods lack precise color control, require color matching specialists, and result in high costs and complex processes. Summary of the Invention
[0008] To address the shortcomings of existing technologies, the purpose of this invention is to provide an integrated spraying and printing weaving system and process.
[0009] To achieve the above objectives, the present invention provides the following technical solution: an integrated spraying and printing weaving system, comprising the following components according to the yarn entry and exit sequence: yarn tube; The inkjet printing module prints and colors each yarn output from the yarn spool using the same or different inks. The electronic yarn storage device is located after the inkjet printing module and serves as an intermediate yarn storage link between the printed yarn and the yarn fed before weaving. A weaving module, located after the electronic yarn storage device, is used to weave the yarn printed by the inkjet printing module into a fabric.
[0010] Furthermore, the integrated spraying and printing weaving system also includes an electronic yarn feeder, which is located between the electronic yarn storage device and the weaving module, and is used to dynamically adjust the yarn feeding rhythm according to the actual yarn consumption rate during weaving.
[0011] Furthermore, the electronic yarn feeder also includes a first parameter, which dynamically adjusts the yarn feeding rhythm by converting the fabric pattern and weave structure into loop lengths and synchronously calculating yarn consumption to match the actual yarn consumption rate during the weaving process.
[0012] Furthermore, the inkjet printing system can be connected to the weaving module in different ways, specifically including: Standalone connection mode: A single inkjet printing system is connected to a single weaving module, processing one yarn at a time; Multi-machine parallel mode: Multiple inkjet printing systems are connected in parallel to a single braiding module to meet the printing needs of multiple yarns; Multi-yarn processing mode: A single inkjet printing system processes multiple yarns simultaneously.
[0013] Furthermore, the weaving module is also equipped with a visual inspection and calibration module, which is used to identify the deviation between the position of a special color signal on the yarn and a specified position, and to adjust the yarn position accordingly. If the color signal lags behind the specified position, the visual inspection and calibration module sends a signal to the needle selection system of the knitting module, instructing it to knit a few more needles in advance to accelerate the arrival of the yarn and make the yarn catch up with the set position. If the color signal arrives at the designated position ahead of schedule, the visual inspection and calibration module sends a signal to the weaving module, instructing it to reduce the amount of yarn used by not weaving the floating thread, so that the yarn is synchronized with the designated position.
[0014] Furthermore, the integrated inkjet printing and weaving system also includes a learning module. This learning module performs comprehensive data analysis on the inkjet printing system by collecting printing parameters from the inkjet printing module, yarn feeding speed and rhythm data from the electronic yarn feeder, and detection results from the visual inspection and calibration module.
[0015] Furthermore, the inkjet printing module is equipped with a drying module for drying the printed yarn, a cleaning module for ultrasonically cleaning the dried yarn, and a lubrication module for lubricating the cleaned yarn.
[0016] Furthermore, the knitting module is specifically a weft knitting machine.
[0017] Furthermore, the inkjet printing module also includes a fixed-length yarn feeding module, which feeds yarn at a constant tension and length according to the yarn feeding instructions from the weaving module, and synchronizes the yarn feeding data to the learning module.
[0018] Furthermore, the inkjet printing module includes either a yarn storage device or a yarn collecting plate, and the yarn outlet end of the yarn storage device or the yarn collecting plate is provided with an inkjet printing yarn outlet structure. The inkjet-printed yarn structure includes an inkjet mount, a yarn channel on the inkjet mount, at least one inkjet ring on the inner wall of the yarn channel, a plurality of nozzles on the inner wall of the inkjet ring, an ink guide channel connected to the inkjet ring in the interlayer of the inkjet mount, an ink guide tube connected to the ink guide channel on the outer wall of the inkjet mount, a waste ink trough arranged longitudinally or transversely on the inner wall of the yarn channel, and an ink discharge tube connected to the waste ink trough on the outer wall of the inkjet mount.
[0019] Furthermore, the yarn storage device has a rotatable yarn storage cylinder inside, and a yarn positioning frame corresponding to the yarn storage cylinder is provided at the end of the yarn storage device. The yarn outlet end of the yarn storage device is connected to the yarn channel.
[0020] Furthermore, the inkjet printing module also includes a yarn collecting plate, which has a plurality of yarn outlet holes that communicate with the yarn channel.
[0021] Furthermore, an inkjet printing process includes the following steps: Step S1: Set the color in advance on the ink supply device connected to the ink guide tube; In step S2, a single yarn enters the inkjet printing module, is guided by the yarn storage device or yarn collection plate, and enters the inkjet printing yarn structure during the output process. It passes through the yarn channel and through the inkjet ring. The nozzles in the inkjet ring spray ink to color the yarn. Excess ink will flow into the waste ink tank and finally be discharged and recycled by the ink discharge pipe. After the yarn is colored, it passes through the drying module, cleaning module and lubrication module in sequence, and finally enters the electronic yarn storage device for buffer storage. Step S3: The electronic yarn storage device winds the yarn synchronously according to the printing speed of the inkjet printing module and stores a certain amount of yarn in advance. The electronic yarn feeder dynamically adjusts the yarn feeding rhythm according to the actual yarn consumption rate of the weaving module and inputs the yarn into the weaving module for weaving. In step S4, while the weaving module is weaving, the visual inspection and calibration module identifies the position of special color signals on the yarn, so that the yarn is synchronized with the specified position. The learning module extracts the yarn data from the above steps and the yarn length data woven by the weaving module, and places the batch of yarns into the printing device. After printing and numbering, the yarns are directly fed into the weaving module by the fixed-length yarn feeder for weaving processing.
[0022] The beneficial effects of this invention are: it simplifies the process by directly printing the weaving process with inkjet printing from a single yarn, improves the environmental friendliness and flexibility of printing, and also has the advantages of personalized customization, improved efficiency, reduced costs, and increased inventory and stocking rates. Inkjet printing can achieve precise point control.
[0023] This application achieves efficient, precise, and intelligent control of the inkjet printing system during yarn weaving through buffer adjustment of the electronic yarn storage device, dynamic yarn feeding of the electronic yarn feeder, real-time calibration of the visual inspection and calibration module, and intelligent optimization of the learning module. These innovative designs not only improve weaving efficiency and ensure precise matching between yarn supply and weaving needs, but also significantly enhance the consistency and stability of product quality, reduce defect rates and yarn waste. At the same time, the system can flexibly adapt to the needs of various production modes and different fabrics, reduce production costs, realize intelligent production, and provide strong support for efficient production in the textile industry.

[0026] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments. Specific implementation method one: Example 1: like Figure 1 As shown, the present invention provides a technical solution for an integrated spraying and printing weaving system: its components, according to the yarn entry and exit sequence, include: Yarn tube 1; Inkjet printing module 2 prints and colors each yarn output from yarn spool 1 using the same or different inks. The electronic yarn storage device 3 is located after the inkjet printing module 2, serving as an intermediate yarn storage link between the printed yarn and the yarn fed before weaving. The weaving module 5 is located after the electronic yarn storage device 3 and is used to weave the yarn printed by the inkjet printing module 2 into a fabric.
[0028] For ease of weaving, the weaving module 5 is specifically a weft knitting machine.
[0029] like Figure 4 or Figure 5 As shown, in order to realize yarn printing and weaving, the inkjet printing module 2 includes either a yarn storage device 21 or a yarn collecting plate 25, and the yarn outlet end of the yarn storage device 21 or the yarn collecting plate 25 is provided with an inkjet printing yarn outlet structure 24. like Figure 6As shown, the inkjet-printed yarn structure 24 includes an inkjet base 2401, a yarn channel 2402 on the inkjet base 2401, at least one inkjet ring 2403 on the inner wall of the yarn channel 2402, a plurality of nozzles 2404 on the inner wall of the inkjet ring 2403, an ink guiding channel 2405 connected to the inkjet ring 2403 in the interlayer of the inkjet base 2401, an ink guiding tube 2406 connected to the ink guiding channel 2405 on the outer wall of the inkjet base 2401, a waste ink tank 2407 arranged longitudinally or transversely on the inner wall of the yarn channel 2402, and an ink discharge tube 2408 connected to the waste ink tank 2407 on the outer wall of the inkjet base 2401.
[0030] To ensure yarn output, a yarn storage cylinder 22 is rotatably provided inside the yarn storage device 21. A yarn positioning frame 23 corresponding to the yarn storage cylinder 22 is provided at the end of the yarn storage device 21. The yarn outlet end of the yarn storage device 21 is connected to the yarn channel 2402. In addition, the inkjet printing module 2 also includes a yarn collecting plate 25, which is provided with a plurality of yarn outlet holes 26, which are connected to the yarn channel 2402.
[0031] Example 2: Example 2 describes a different connection method between the inkjet printing system of this application and the knitting module 5 (weft knitting machine): like Figure 1 and Figure 2 As shown, to improve weaving efficiency, the inkjet printing system can be connected to the weaving module 5 in different ways, specifically including: Single-machine connection mode: A single inkjet printing system is connected to a single braiding module 5 to process one yarn at a time; Multi-machine parallel mode: Multiple inkjet printing systems are connected in parallel to a single braiding module 5 to meet the printing needs of multiple yarns; Multi-yarn processing mode: A single inkjet printing system processes multiple yarns at the same time.
[0032] (1) Standalone connection mode: In stand-alone mode, a single inkjet printing system connects to the weft knitting machine to process a single yarn. This mode is suitable for small-scale production or scenarios requiring high-precision printing of a single yarn. For example, in the production of a small circular knitting machine (8 yarn feeders), stand-alone mode ensures the printing quality and color accuracy of each yarn. In this way, the inkjet printing system can accurately print and color the yarn according to the fabric pattern and weave structure. At the same time, the electronic yarn feeder 4 dynamically adjusts the yarn feeding rhythm according to the actual yarn consumption rate of the knitting module 5 to ensure the smooth progress of the knitting process.
[0033] (2) Multi-machine parallel mode: In multi-machine parallel mode, multiple inkjet printing systems are connected in parallel to the weft knitting machine to meet the printing needs of multiple yarns. This mode is suitable for large-scale production and multi-color fabric production scenarios. For example, when producing fabrics with complex patterns and multiple colors, assuming the weft knitting machine has more than 100 yarns, multiple inkjet printing systems can be connected in parallel to the machine simultaneously. Each inkjet printing system is responsible for printing different colors or different parts, achieving efficient yarn printing and knitting through collaborative work. In this mode, the learning module 7 can collect data from each inkjet printing system and the knitting module 5 to optimize printing parameters and yarn feeding rhythm, further improving production efficiency and product quality.
[0034] (3) Multi-yarn processing mode: In the multi-yarn processing mode, one inkjet printing system processes multiple yarns simultaneously, connected to the weaving module 5. Taking a small circular knitting machine as an example, assuming it needs to process four yarns, two inkjet printing systems can be configured, each processing two yarns. This mode is suitable for scenarios requiring simultaneous printing of multiple yarns with the same or similar tasks, reducing redundant equipment configuration and improving equipment utilization. By processing multiple yarns simultaneously, the inkjet printing system can significantly improve production efficiency while ensuring print quality. Furthermore, the vision inspection and calibration module 6 can monitor the accuracy of yarn positions in real time, ensuring that multiple yarns maintain a consistent positional relationship during the weaving process.
[0035] Through the three connection methods mentioned above, the inkjet printing system can flexibly adapt to different production needs, achieving efficient and accurate yarn printing and weaving processes, thereby maximizing printing efficiency.
[0036] Example 3: like Figure 3 As shown, in order to improve yarn strength, the inkjet printing module 2 is equipped with a drying module for drying the printed yarn, a cleaning module for ultrasonic cleaning of the dried yarn, a lubrication module for lubricating the cleaned yarn, and a fixed-length yarn feeding module for feeding yarn at constant tension and length according to the yarn feeding instructions of the weaving module 5.
[0037] In this application, the temperature of the drying module is set to 80-120℃. Its internal hot air circulation system uses a heating device to heat the air to the set temperature (usually 80℃-120℃), so that the hot air circulates in the closed space. The flow of hot air not only removes the moisture from the surface of the yarn, but also causes the fiber molecules in the yarn to quickly arrange and fix under the action of high temperature and air flow, forming a stable morphological structure, thereby achieving rapid shaping and effectively removing excess moisture from the yarn.
[0038] In the cleaning module of this application, the brush rotation speed is 200-3000 rpm (the corresponding rotation speed is different depending on the yarn material, and is determined by a preset value). Through the high-speed rotation of the flexible brush, friction is generated with the yarn surface, and impurities and fuzz are peeled off from the yarn surface. This can effectively remove impurities and fuzz from the yarn surface, reduce the roughness of the yarn surface, improve the surface smoothness, and reduce the breakage rate during weaving.
[0039] In this application, the lubricant in the lubrication module is evenly sprayed onto the yarn surface through a micro-orifice nozzle, forming a thin lubricating layer. This reduces friction between the yarn and the weaving equipment, as well as between the yarns themselves, thereby lowering the coefficient of friction during weaving, reducing yarn wear, extending yarn lifespan, and improving weaving efficiency.
[0040] The fixed-length yarn feeding module in this application can perform constant tension fixed-length yarn feeding operation according to the yarn feeding instructions of the weaving module 5. By precisely controlling the yarn feeding length and tension, it ensures that the yarn maintains a consistent tension and length during the weaving process, thereby improving the weaving quality and efficiency. This precise yarn feeding mechanism can effectively reduce yarn waste, avoid weaving defects caused by uneven tension or inaccurate length, and ensure the quality and consistency of the fabric.
[0041] Example 4: In this embodiment, the inkjet printing system achieves precise matching and dynamic control of yarn during the weaving process through the collaborative mechanism between the electronic yarn storage device 3, the electronic yarn feeder 4, and the visual inspection and calibration module 6.
[0042] (1) Buffer adjustment of electronic yarn feeder: The electronic yarn storage device 3 serves as an intermediate yarn storage link between the printed yarn and the weaving process. Its winding speed is strictly synchronized with the printing speed of the inkjet printing module 2. In actual production, the electronic yarn storage device 3 stores a certain amount of yarn in advance to cope with the fluctuations in the amount of yarn used during the weaving process. This design aims to avoid unstable yarn supply caused by the imbalance between supply and demand by pre-storing yarn, thereby ensuring the smooth progress of the weaving process. In this application, the structure of the electronic yarn storage device 3 is similar to that of the yarn storage device 21, but its storage capacity and size are larger than those of the yarn storage device 21.
[0043] (2) The real-time yarn feeding speed of the electronic yarn feeder is adapted to the knitting speed: In order to dynamically adjust the yarn, the electronic yarn feeder 4 is located between the electronic yarn storage device 3 and the weaving module 5, and is used to dynamically adjust the yarn feeding rhythm according to the actual yarn consumption rate during weaving.
[0044] In order to match the actual yarn consumption rate, the electronic yarn feeder 4 also includes a first parameter. The first parameter converts the fabric pattern and weave structure into loop length and calculates the yarn consumption synchronously, thereby dynamically adjusting the yarn feeding rhythm to match the actual yarn consumption rate during the weaving process.
[0045] The electronic yarn feeder 4 features yarn length detection and precise control, dynamically adjusting the yarn feeding rhythm based on the actual yarn consumption rate of the knitting module 5. Specifically, it monitors the yarn feeding status of the printed yarn in real time through the pattern knitting processing software of the weft knitting equipment and the yarn feeding software of the yarn feeder. When pattern knitting requires rapid yarn use, the yarn feeder automatically increases the yarn feeding speed; conversely, when pattern knitting requires slow yarn use, the yarn feeder slows down the yarn feeding speed. In this way, the electronic yarn feeder 4 can balance yarn supply and demand in real time, maintaining precise synchronization between the printed yarn and the knitting yarn.
[0046] (3) Linkage calibration of the visual inspection calibration module and the needle selection system: To synchronize the yarn with the designated position, the weaving module 5 is also equipped with a visual detection and calibration module 6, which is used to identify the deviation between the position of a special color signal on the yarn and the designated position, and adjust the yarn position accordingly. If the color signal lags behind the specified position, the visual inspection and calibration module 6 sends a signal to the needle selection system of the knitting module 5, instructing it to knit a few more needles in advance to accelerate the arrival of the yarn and make the yarn catch up with the set position. If the color signal arrives at the designated position ahead of schedule, the visual inspection and calibration module 6 sends a signal to the weaving module 5, instructing it to reduce the amount of yarn used by not weaving the floating thread, so that the yarn is synchronized with the designated position.
[0047] On the weft knitting equipment, special color signals are set at specific positions of the yarn. Together with the independent yarn correction system with needle selection control and the visual inspection and calibration module 6 set on the equipment, the visual inspection and calibration module 6 accurately identifies the position of the special color signal on the yarn and links the needle selection system to control the length of the yarn.
[0048] This application achieves precise matching and dynamic control of yarn during the weaving process through the buffer adjustment of the electronic yarn feeder 3, the real-time yarn feeding speed adjustment of the electronic yarn feeder 4, and the linkage calibration of the visual inspection and calibration module 6 and the needle selection system. This collaborative mechanism not only improves weaving efficiency but also ensures the quality and consistency of the fabric.
[0049] Example 5: Based on embodiment 4, this application also employs a learning module 7. The learning module 7 performs comprehensive data analysis on the inkjet printing system by collecting the printing parameters of the inkjet printing module 2, the yarn feeding speed and rhythm data of the electronic yarn feeder 4, and the detection results of the visual inspection and calibration module 6.
[0050] (1) Data acquisition and preprocessing: Learning module 7 first collects printing parameters from inkjet printing module 2, including printhead drive waveform data (such as delay time, rise time, hold time, fall time, and hold voltage) and inkjet quality evaluation parameters (such as droplet velocity and droplet volume). At the same time, it obtains yarn feeding speed and rhythm data from electronic yarn feeder 4, and obtains detection results such as yarn position deviation and color signal position from vision inspection and calibration module 6. These data are preprocessed (such as noise reduction, filling missing values, and deduplication) to improve data quality.
[0051] (2) Data analysis and model building: Based on the collected data, the learning module 7 constructs an inkjet quality assessment model. This model is optimized through data mining and machine learning algorithms. For example, by calculating the vector mean and covariance matrix of each sampling point in the sample dataset, a Gaussian function is constructed to improve the stability and optimization efficiency of the model. In addition, the learning module 7 can also adjust the model parameters according to real-time feedback to adapt to different production needs.
[0052] (3) Parameter optimization and real-time adjustment: Based on the constructed model and real-time data, the learning module 7 optimizes the printing parameters of the inkjet printing module 2 to ensure the accuracy of yarn color and pattern. At the same time, it dynamically adjusts the yarn feeding speed of the electronic yarn feeder 4 to accurately match the actual yarn consumption rate of the weaving module 5 and avoid unstable yarn supply. The learning module 7 also calibrates the yarn position in real time based on the feedback from the visual inspection and calibration module 6 to ensure the accuracy of the yarn during the weaving process.
[0053] Through the aforementioned optimizations and adjustments, the learning module 7 achieves intelligent collaborative control among the inkjet printing module 2, the electronic yarn feeder 4, and the vision inspection and calibration module 6. This collaborative mechanism not only improves weaving efficiency but also significantly enhances the consistency and stability of product quality. For example, when producing fabrics with complex patterns, the learning module 7 can adjust the parameters of each module based on real-time data to ensure the printing and weaving accuracy of each yarn, thereby maximizing production efficiency.
[0054] In summary, Learning Module 7 provides powerful technical support for inkjet printing systems through intelligent data acquisition, analysis, and optimization, enabling them to flexibly respond to different production needs and achieve efficient and precise weaving processing. Specific Implementation Method Two: like Figure 7 As shown, an inkjet printing process includes the following steps: Step S1: Set the color in advance on the ink supply device connected to the ink guide tube 2406; In step S2, a single yarn enters the inkjet printing module 2, is guided by the yarn storage device 21 or the yarn collection plate 25, and enters the inkjet printing yarn structure 24 during the output process. It passes through the yarn channel 2402 and the inkjet ring 2403. The nozzles 2404 in the inkjet ring 2403 spray ink to color the yarn. Excess ink will flow into the waste ink tank 2407 and finally be discharged and recycled by the ink discharge pipe 2408. After the yarn is colored, it passes through the drying module, the cleaning module and the lubrication module in sequence, and finally enters the electronic yarn storage device 3 for buffer storage. Step S3: The electronic yarn storage device 3 winds the yarn synchronously according to the printing speed of the inkjet printing module 2 and stores a certain amount of yarn in advance. The electronic yarn feeder 4 dynamically adjusts the yarn feeding rhythm according to the actual yarn consumption speed of the weaving module 5 and inputs the yarn into the weaving module 5 for weaving. In step S4, while the weaving module 5 is weaving, the visual detection and calibration module 6 identifies the position of special color signals on the yarn, so that the yarn is synchronized with the specified position. The learning module 7 extracts the yarn data from the above steps and the yarn length data woven by the weaving module 5, and places the batch of yarns into the printing device. After printing and numbering, the yarns are directly fed into the weaving module 5 by the fixed-length yarn feeder for weaving processing.

An inkjet printing process, derived by operating the inkjet printing system according to any one of claims 1-9, the process comprising the following steps: Step S1: Set the color in advance on the ink supply device connected to the ink guide tube (2406); In step S2, a single yarn enters the inkjet printing module (2), and is guided by the yarn storage device (21) or the yarn collection plate (25) to enter the inkjet printing yarn structure (24) during the output process. It passes through the yarn channel (2402) and passes through the inkjet ring (2403). The nozzle (2404) in the inkjet ring (2403) sprays ink to color the yarn. Excess ink will flow into the waste ink tank (2407) and finally be discharged and recycled by the ink discharge pipe (2408). The colored yarn passes through the drying module, the cleaning module and the lubrication module in sequence, and finally enters the electronic yarn storage device (3) for buffer storage. Step S3, the electronic yarn storage device (3) winds the yarn synchronously according to the printing speed of the inkjet printing module (2) and stores a quantitative amount of yarn in advance. The electronic yarn feeder (4) dynamically adjusts the yarn feeding rhythm according to the actual yarn consumption speed of the weaving module (5) and inputs the yarn into the weaving module (5) for weaving. In step S4, while the weaving module (5) is weaving, the visual detection and calibration module (6) identifies the position of the special color signal on the yarn, so that the yarn is synchronized with the specified position. The learning module (7) extracts the yarn data from the above steps and the yarn length data woven by the weaving module (5), and places the batch of yarns in the printing device. After printing and numbering, the yarns are directly fed into the weaving module (5) by the fixed-length yarn feeder for weaving processing.
