TECHNICAL FIELD
[0001] The utility model relates to the field of textile machinery, specifically, a yarn collecting system with inkjet dyeing function. BACKGROUND
[0002] The textile industry has always been an important part of the global economy, with the progress of technology and the diversification of consumer demand, the requirements for textiles are also getting higher and higher. Modern consumers not only pursue the functionality and comfort of fabrics, but also pay great attention to the color and appearance effect of fabrics. Traditional dyeing methods, such as dip dyeing and spray dyeing, although meet market demand to some extent, these methods have many shortcomings, such as high water consumption, high wastewater discharge, poor dyeing uniformity, etc., especially in today's growing environmental awareness, these problems become more prominent.
[0003] In the field of warp knitting, due to its high production efficiency and strong flexibility, it has become an important branch of the textile industry. Warp knitting machine can produce large area of fabric in a short time by using multiple groups of yarns. However, traditional warp knitting technology can only produce products with single color or simple pattern, if more complex design or color gradient effect is required, additional dyeing or printing process is needed after weaving, which undoubtedly increases the production cost and complexity.
[0004] In addition, for some specific types of yarns, such as transparent monofilament (such as polyester monofilament), due to its colorless transparency, it faces more challenges when using traditional dyeing methods. In order to make the transparent monofilament have the required color, special dyes and dyeing process are often used, which may make the dyeing process more complex and difficult to control the consistency and stability of the color. Or the yarn is too elastic, or the high temperature dyeing is easy to shrink the yarn, which is not suitable for traditional post-dyeing, which may cause problems such as texture deformation, color fastness unqualified, etc.
[0005] In recent years, with the development of digital technology, some new concepts and technologies have also been introduced into the textile industry, such as digital inkjet printing technology. This technology is initially mainly used for printing on paper and flat materials, but due to its non-contact printing characteristics, it has also been gradually applied to textile printing. The advantage of digital inkjet printing technology is that it can realize highly customized pattern design, and can quickly change different patterns, greatly improving the flexibility of production.
[0006] However, the current inkjet printing technology is mainly applied to finished fabrics, and there is relatively little research on how to directly process the color during the yarn production and weaving process, especially for warp knitting, which requires a large number of yarns to be woven simultaneously.
[0007] In summary, how to ensure production efficiency while achieving more environmentally friendly, economic solution to realize multi-color, complex pattern dyeing in the yarn weaving process has become one of the problems to be solved in the current textile industry, especially in the warp knitting field.

[0066] Embodiment 6:
[0067] An operation mode of a yarn collecting system with inkjet dyeing function, specifically:
[0068] Step S1: The yarn collecting plate 1 is arranged between the creel and the warp knitting machine, and the print head 6 is connected to the control terminal 5, the dye tank 3 and the waste tank 11 respectively.
[0069] Specifically, first, the yarn collecting plate 1 is fixed on the support between the creel and the warp knitting machine, ensuring that the yarn collecting plate 1 is stable and does not shake. The height of the yarn collecting plate 1 should be set at a position where the yarn from the creel to the warp knitting machine can be kept as straight as possible, so that the yarn does not experience a sharp change in tension when passing through the dyeing system 2 of the yarn collecting plate 1.
[0070] The print head 6 or print group 8 arranged on the yarn collecting plate 1 or the print support 12 is connected to the dye tank 3 through the material conveying pipe 7 and connected to the control terminal 5 integrated on the warp knitting machine through the circuit, and the waste ink collecting groove arranged on the dyeing system 2 is connected to the waste tank 11 through the waste pipe 10.
[0071] Step S2: The yarn is connected to the warp knitting machine through the yarn passing hole 4 of the yarn collecting plate 1 according to the design requirements, so that each yarn corresponds to a print head 6 or print group 8.
[0072] Specifically, the yarn is sequentially passed through the corresponding yarn collecting plate 1 designated yarn passing hole 4 hole position and connected to the corresponding warp knitting machine knitting needle position according to the needs of the knitting design, so that the control terminal 5 can accurately dye the corresponding color on the yarn at the corresponding position during the dyeing operation.
[0073] Step S3: Start the warp knitting machine, and the traction mechanism of the warp knitting machine pulls the yarn forward to perform knitting operation; the control terminal 5 controls the dye tank 3 to output a specified amount and color of dye according to the preset dyeing scheme, and delivers the dye to the print head 6 or print group 8 through the material conveying pipe 7 to perform inkjet dyeing on the yarn, so that the yarn is dyed with the specified color according to the design.
[0074] Specifically, first, the power of the warp knitting machine is turned on, and the operating parameters of the warp knitting machine are set, including the running speed of the yarn, tension, etc. The running speed of the yarn should match the jet dyeing speed. Then the control terminal 5 is turned on, and the preset jet dyeing scheme is loaded, which includes the jet dyeing color parameters of each yarn, the jet amount of the dye, the jet time, etc. Then the warp knitting machine is started, and the traction mechanism of the warp knitting machine starts to pull the yarn forward, while the control terminal 5 starts to control the dye bin 3 to output a specified amount and a specified color of the dye according to the preset jet dyeing scheme, and the dye is transported to the print head 6 through the material conveying pipe 7. The print head 6 sprays the dye on the yarn when it passes according to the instruction of the control terminal 5. The jet amount and the jet time of the dye are accurately controlled by the control system according to the preset jet dyeing scheme, so as to ensure that each yarn can be dyed to the specified color. The dyed yarn continues to advance and passes through the fixing device 14 for fixing treatment, and then is pulled to the needle bed for knitting by the warp knitting machine.
[0075] It should be clear to those skilled in the art that the embodiments in the present application are only for more complete and comprehensive display of all technical elements of the present application, but in actual application process, since the print head 6 is small in size and the control terminal 5 is accurate in controlling the output amount of the dye, basically no dye is scattered outside the yarn, so the waste pipe 10 and the waste bin 11 are unnecessary technical features, and they appear in the embodiments only for the safest scheme, so the yarn yarn collecting system with inkjet dyeing function without the waste pipe 10 and the waste bin 11 is also within the protection scope of the present application.
[0076] The above describes the present application and its embodiments in a schematic manner, which is not restrictive, and the embodiments shown in the drawings are only one of the embodiments of the present application, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by it, without departing from the creative purpose of the present application, similar structural modes and embodiments can be designed without creativity, which should all belong to the protection scope of the present application.
