Description

Technical Field

[0001] This utility model belongs to the field of textile technology, specifically relating to a warping system with an inkjet printing module. 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 affect the fabric's feel and durability. In the field of warp knitting, although its production speed and flexibility are high, it still has certain limitations in color processing. Traditional warp 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 treatments are required after weaving. This not only increases production costs and complexity but may also lead to problems such as uneven dyeing. To simplify the production process and reduce environmental pollution, the textile industry has been seeking methods to achieve color changes directly during weaving. For example, inkjet technology disperses pigments 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 may also lead to environmental pollution and increased costs. On the other hand, although jacquard technology can create a gradient effect on fabrics through the combination of different yarns and stitch patterns, its drawing efficiency is low and it requires a lot of manual drawing, which prolongs the production cycle, and the jacquard effect looks unnatural when viewed up close.

[0003] 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. Furthermore, the post-dyeing treatment of yarn is also a crucial step. In traditional dyeing processes, the yarn's tension and crimp change due to variations in moisture after dyeing, requiring re-warping to restore tension consistency and morphological stability. This process not only increases production steps but can also affect the quality of the final product.

[0004] To overcome these problems, researchers began exploring methods to integrate dyeing functions into warp knitting machines. Currently, some research focuses on how to place inkjet devices at different locations on the warp knitting machine to achieve online dyeing. However, most of these methods fail to achieve continuous and independent dyeing of the fabric, resulting in uneven dyeing effects and unstable tension control. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of the embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] A warping system with an inkjet printing module 40, comprising, in sequence from yarn travel, a yarn supply module 10, a tension holding module, an inkjet printing module 40, and a warping module, wherein, for example... Figure 1 As shown:

[0037] Yarn supply module 10, which is located at the front end of the system, stores and supplies yarn to the system;

[0038] The tension maintaining module is located at the rear end of the yarn supply module 10. The tension maintaining module includes a yarn collecting plate 20 and a tension roller 30. After the yarn is output from the yarn supply module 10, it first passes through the yarn collecting plate 20 to be bundled and then enters the tension roller 30 for tension adjustment.

[0039] The inkjet printing module 40 includes a print control terminal 61 and an inkjet printing terminal 41. The inkjet printing terminal 41 is located at the rear end of the tension holding module and is wirelessly or electrically connected to the print control terminal 61. Figure 2 The inkjet printing terminal 41 shown includes a print head 45, a dye tank 49, and an ink supply tube 44. The print head 45 is connected to the dye tank 49 through the ink supply tube 44. The printing control terminal 61 is integrated on the main unit and is connected to the print head 45 in the inkjet printing terminal 41 via wireless or circuit connection.

[0040] Because the bundled yarns travel closely side-by-side, the inkjet printing terminal 41 cannot perform printing on a single yarn. It needs to print across at least a portion of the yarn, requiring the print head 45 to be able to move within a certain range. Therefore, the inkjet printing terminal 41 is also equipped with features such as… Figure 2 The sliding mechanism shown includes a sliding bracket 42 and a drive device 43. The drive device 43 is mounted on the print head 45 and is movably connected to the sliding bracket 42. This allows the drive device 43 to drive the print head 45 to reciprocate for wide-width printing. Due to the warping width, the reciprocating printing speed of the print head 45 may not match the yarn travel speed in some cases. Therefore, the setting of the inkjet printing terminal 41 will be as follows... Figure 3 The setup shown has two or more settings, and the yarn bundle 50 is spray-dyed in segments;

[0041] During actual equipment operation, the inkjet printing terminal 41 can be configured in different ways according to the actual on-site environment. The first way is as follows: Figure 1 As shown, an inkjet printing terminal 41 is independently installed at the rear end of the tension roller 30. After the yarn is adjusted by the tension roller 30, it enters the inkjet printing terminal 41 for inkjet dyeing. A waste ink collection tank 46 is provided at the bottom of the inkjet printing terminal 41 to collect the waste ink splashed outside the yarn area. The waste ink collected in the waste ink collection tank 46 is connected to the waste ink tank 48 for collection through the waste ink tube 47.

[0042] The second method is as follows Figure 4 As shown, the inkjet printing terminal 41 is mounted on the tension roller 30. While the yarn enters the tension roller 30 and the tension is adjusted, the inkjet printing terminal 41 performs inkjet dyeing on the yarn. A dye scraper 32 (e.g., ...) is tightly fitted onto the tension roller 31 of the tension roller 30. Figure 5 As shown), the dye doctor blade 32 can scrape off the waste ink adhering to the tension roller 31 in real time to prevent the waste ink from contaminating the yarn that subsequently enters the tension roller 30 for tension adjustment. A waste ink box 33 is provided at the bottom of the tension roller 31 to collect the waste ink scraped off the tension roller 31 by the dye doctor blade 32.

[0043] In order to prevent the yarn bundle 50 after tension adjustment from sagging due to excessive travel distance and tension change, the yarn from the tension holding module to the warping module is usually short. When the inkjet-dyed yarn is stored on the warp beam of the warping host 60 in the warping system, the ink will contaminate other yarns around it because it has not yet dried and fixed. Therefore, a drying device 80 is also provided at the rear end of the inkjet printing terminal 41. The drying device 80 is preferably a hot drying device to hot dry and fix the inkjet-dyed yarn, ensuring that the color of the dyed yarn is stable and will not contaminate the surrounding yarns. It is not recommended to use air drying equipment for the drying device 80 to prevent the yarn bundle 50 from changing tension during the air drying process.

[0044] During the warping process, the spacing between the yarns in the yarn bundle 50 is very short, and static electricity is generated due to friction during the journey, which affects the inkjet printing terminal 41's dyeing effect and the quality of the subsequent woven products. Therefore, an antistatic device 70 needs to be installed at the front or rear end of the inkjet printing terminal 41. When the warping system is equipped with a drying device 80, the antistatic device 70 is installed at the rear end of the drying device 80. To improve the quality of inkjet dyeing and subsequent woven products, the preferred solution is to install antistatic devices 70 at both the front end of the inkjet printing terminal 41 and the rear end of the drying device 80.

[0045] The warping system is equipped with a warping module at the end. The warping module includes a warping host 60 and a warp beam. The warp beam is rotatably connected to the warping host 60 and is used to store the yarn after tension adjustment and inkjet dyeing, in preparation for use on the machine.

[0046] As attached Figure 6 As shown, when only one inkjet printing terminal 41 is set in a single vertical direction, the yarn may not be dyed completely, that is, only a part of the upper surface of the yarn is dyed, while the rest is not dyed. Therefore, two or more inkjet printing terminals 41 can be set in the vertical direction, and the print heads 45 of the two inkjet printing terminals 41 are tilted relative to each other to form an angle between 30° and 120°. Through the cooperation of the two print heads 45, the dyeing area is larger than that of a single print head 45, and the dyeing effect of the yarn is better.

[0047] As attached Figure 7 As shown, when the yarn bundle 50 passes through the tension roller 30, if a single inkjet printing terminal 41 is only set on the top of the yarn, the inkjet printing terminal 41 may only print a portion of the upper surface of the yarn, leaving the lower surface unprinted. However, if the inkjet printing terminal 41 is only set on the corresponding lower surface of the yarn, the inkjet terminal below the yarn will spray dye vertically upwards, causing excess dye to fall and contaminate the print head 45, or the dye may be carried back to the subsequent portion of the yarn by the dye sprayed later during the fall, causing the yarn to become stained. To address the deviation, two tension rollers 31 can be configured on the tension roller 30, one at the yarn inlet and one at the yarn outlet. A pressure roller 34 is positioned below the two tension rollers 31, causing the yarn bundle 50 to travel in a "V" shape. Two inkjet printing terminals 41 are positioned opposite each other between the pressure roller 34 and the tension roller 31 at the yarn outlet. These two inkjet printing terminals 41 are located on both sides of the yarn bundle 50, ensuring that both sides of the yarn bundle 50 are evenly and accurately dyed.

[0048] An operation method of a warping system with an inkjet printing module 40: the yarn is drawn out from the yarn supply module 10, passes through the tension holding module and the inkjet printing module 40 and enters the warping module to complete the warping of the yarn bundle 50. When the yarn passes through the inkjet printing module 40, the inkjet printing module 40 performs inkjet dyeing on the yarn according to a preset inkjet scheme.

[0049] A drying device 80 is provided at the rear end of the inkjet printing module 40. After the yarn is dyed by inkjet printing module 40, it is dried and fixed by drying device 80.

[0050] Specifically:

[0051] S1. The pre-inkjet dyeing pattern file is imported into the printing control terminal 61 integrated on the warping host 60. The printing control terminal 61 converts the file into a control signal and transmits it to the inkjet printing terminal 41 via a wireless network or circuit. The print head 45 in the inkjet printing terminal 41 receives the instruction and moves to the starting position of the sliding bracket 42 via the drive device 43. At the same time, the ink dye in the dye tank 49 is delivered to the print head 45 through the ink supply tube 44 to prepare for the inkjet dyeing work.

[0052] S2. The yarn is conveyed from the yarn supply module 10, bundled into a yarn bundle 50 by the yarn collecting plate 20, and then subjected to the first static elimination device for the first static elimination. It then enters the tension roller 30 for tension adjustment. Once the yarn enters the tension roller 30, the print control terminal 61 sends a print command to the inkjet print terminal 41. The print head 45 in the inkjet print terminal 41 reciprocates on the sliding bracket 42 via the drive device 43, spraying the pattern from the pattern file onto the yarn bundle 50. Ink and dye splashed outside the area of ​​the yarn bundle 50 are collected by the waste ink collection tank 46 and transferred to the waste ink container 48 for storage via the waste ink pipe 47. It should be noted here that... When the inkjet printing terminal 41 is mounted on the tension roller 30, ink splashed outside the yarn bundle 50 area will adhere to the tension roller 31. After the ink-laden tension roller 31 rotates once, the ink cannot automatically detach from the tension roller 31 and will adhere to the yarn that subsequently enters the tension roller 30, causing color mixing and contamination. Therefore, a dye scraper 32 needs to be closely fitted on the tension roller 31 to scrape off the ink adhering to the tension roller 31. The dye scraper 32 is preferably located in the lower outer periphery area of ​​the tension roller 31. At the same time, a waste ink tank 48 is provided in the cavity area of ​​the tension roller 30 below the dye scraper 32 to collect the waste ink and dye scraped off by the dye scraper 32.

[0053] S3. After the dyed and tension-adjusted yarn bundle 50 is dried, fixed, and subjected to secondary static removal, it is stored on the warp beam that is rotatably connected to the warping host 60.

[0054] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
