Description

Technical Field

[0001] The invention relates to the technical field of textile machinery, in particular to a yarn collecting system with inkjet dyeing function and an operating method thereof. Background Art

[0002] The textile industry has always been an important part of the global economy. With the advancement of technology and the diversification of consumer demand, the requirements for textiles are becoming higher and higher. Modern consumers not only pursue the functionality and comfort of fabrics, but also attach great importance to the color and appearance of fabrics. Although traditional dyeing methods, such as dip dyeing and spray dyeing, have met market demand to a certain extent, these methods have many shortcomings, such as high water consumption, high wastewater discharge, poor dyeing uniformity, etc., especially today with the increasing awareness of environmental protection, these problems have 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 machines can produce large areas of fabric in a short time by using multiple groups of yarns. However, traditional warp knitting technology can only produce products of a single color or simple pattern. To achieve more complex designs or color gradient effects, additional dyeing or printing processes are required after weaving, which undoubtedly increases production costs and complexity.

[0004] In addition, for certain types of yarn, such as transparent monofilament (such as polyester monofilament), due to its inherent colorlessness and transparency, it faces more challenges when using traditional dyeing methods. In order to make transparent monofilament have the desired color, special dyes and dyeing processes are often required, which may make the dyeing process more complicated and difficult to control the consistency and stability of the color. Yarns with too high elasticity or yarns that are prone to shrinkage due to high-temperature dyeing are not suitable for traditional post-dyeing, which can easily lead to problems such as texture deformation and unqualified color fastness.

[0005] In recent years, with the development of digital technology, some new concepts and technologies have been introduced into the textile industry, such as digital inkjet printing technology. This technology was originally used mainly for printing 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 achieve highly customized pattern design and can quickly change different patterns, greatly improving production flexibility.

[0006] However, current inkjet printing technology is mainly used on finished fabrics. There is relatively little research on direct color processing during the yarn production and weaving process, especially on how to dye independent yarns for warp knitting, which requires a large number of yarns to be woven simultaneously.

[0007] In summary, how to achieve a more environmentally friendly and economical solution for dyeing multi-color and complex patterns during yarn weaving while ensuring production efficiency has become one of the urgent problems to be solved in the current textile industry, especially in the field of warp knitting. Summary of the invention

[0008] In order to solve the technical problem of realizing color treatment in the yarn production and weaving process in the above-mentioned prior art, the present invention provides a yarn collecting system with inkjet dyeing function and an operating method thereof.

[0009] [The present invention discloses a yarn collection system with inkjet dyeing function] A yarn collecting system with inkjet dyeing function comprises three parts: a collecting plate, a dyeing system and a dye bin, wherein the collecting plate is provided with a plurality of threading holes, the dyeing system comprises a control terminal, a print head and a feed pipe, each threading hole on the collecting plate is provided with at least one print head, and each of the print heads is connected to the dye bin through at least one feed pipe, the control terminal is arranged on the outside of the collecting plate, the control terminal is connected to each print head and independently controls each print head to perform a dyeing operation on the yarn passing through the corresponding threading hole.

[0010] On the basis of the above basic technical scheme, multiple wire collecting plates can also be arranged side by side to form a wire collecting plate group for coordinated spray dyeing operations. The multiple wire collecting plates are spaced a certain distance apart and the positions of the wire threading holes on the wire collecting plates correspond one to one, so that the yarn can pass through each wire collecting plate straight and smoothly from the wire threading hole. Each wire threading hole on the wire collecting plate is provided with at least one print head, and all the print heads on each wire collecting plate only control one color of dye for spray dyeing operations, and multiple wire collecting plates cooperate with each other to complete the multi-color spray dyeing operation of the yarn.

[0011] On the basis of the basic technical solution, the solution of the wire collecting plate group can also be replaced by the solution of the print head group, that is, a plurality of pluggable print heads are set at the print head position corresponding to each wire threading hole, and the plurality of print heads constitute a printing group, and each print head in each printing group is connected to the dye bin through a feed pipe, and each print head only controls one color of dye for spraying operation, and the plurality of print heads in each printing group cooperate with each other to complete the multi-color spraying operation of the yarn.

[0012] On the basis of the above three schemes, the base fabric of the threading hole is provided with a waste collecting trough, the tail end of the waste collecting trough is connected with a waste pipe, and is connected with a waste bin arranged outside the equipment through the waste pipe.

[0013] Based on the above three schemes, another spray-dyeing setting method is provided, that is, the spray-dyeing system is not arranged on the wire collecting plate, but a printing bracket is movably connected to the wire collecting plate, and the printing bracket movably connected to the wire collecting plate covers at least one area of ​​the wire collecting plate, and a front-to-back through-spray-dyeing channel is arranged at a position corresponding to the wire threading hole of the wire collecting plate, and each spray-dyeing channel is provided with at least one print head, and each print head is connected to the dye bin through at least one feed pipe, and the print heads are connected to the control terminal.

[0014] On the basis of the previous technical solution, a waste collection trough is provided at the bottom of the spray-dyeing channel on the printing bracket. The waste collection trough is connected and penetrated inside the printing bracket, and is connected to the waste bin through a waste pipe at the bottom of the printing bracket, so as to collect the dye waste generated during the spray-dyeing operation and transport it to the waste bin.

[0015] On the basis of the above technical solution, the number of the multiple print heads or print head groups arranged in each wire threading hole or dyeing channel is three and they are distributed in an isosceles triangle around a center point.

[0016] On the basis of the above technical solution, a color fixing device can be arranged at the rear end of the spray dyeing system, and the color fixing device is a drying device and / or an air drying device.

[0017] [The present invention also discloses an operation method of a yarn collecting system with inkjet dyeing function] An operating method of a yarn collecting system with inkjet dyeing function: S1: The wire collecting plate is arranged on the textile equipment, and the printing head or the printing group is connected to the dye bin through the feeding pipe; the waste collecting tank is connected to the waste bin through the waste pipe, and the control terminal is connected to each printing head; S2: Connect the yarn to the textile equipment through the threading holes of the thread collecting plate according to the design, so that each yarn corresponds to a printing head or printing group; S3: Turn on the textile equipment, and the textile equipment controls the yarn traction mechanism to pull the yarn forward; the control terminal controls the dye bin to output a specified amount and color of dye according to a preset spraying scheme, and transports the dye to the print head or printing group through a feed pipe to inkjet dye the yarn, so that the yarn is spray-dyed with the specified color according to the design.

[0018] The present invention proposes a yarn collection system with inkjet dyeing function and an operation method thereof, aiming to overcome the problems of low efficiency, high cost and environmental pollution existing in traditional dyeing methods. Compared with the existing dyeing technology, the present invention has the following significant beneficial effects: 1. Efficiency improvement: The present invention realizes the process of directly dyeing the yarn during the weaving process by setting a spray dyeing system on the yarn collecting plate. The woven fabric directly has the final color pattern effect, which reduces many subsequent processing steps required in the traditional production process, shortens the production cycle, and improves production efficiency.

[0019] 2. Environmental protection and energy saving: Traditional dyeing methods often require the use of a large amount of chemical reagents and produce a large amount of wastewater discharge. The technical solution of the present invention directly sprays the dye on the yarn by accurately controlling the spray amount of the dye, reducing the use of a large amount of chemical reagents and the generation of wastewater for rinsing. At the same time, a waste ink collection tank is set up to effectively recycle unused dyes in the surrounding area, reducing the waste of dyes and greatly reducing the pollution impact on the environment.

[0020] 3. Cost reduction: The technical solution of the present invention directly performs inkjet dyeing of yarns during the weaving production process, without the need for subsequent additional traditional dyeing treatment, thus reducing the investment of a large amount of manpower and physical resources; at the same time, the control terminal accurately controls the quantitative output of the dye, reducing unnecessary dye waste, and the waste collection tank's recycling and reuse of waste ink also greatly reduces dye waste, significantly reducing production costs.

[0021] 4. Color accuracy and consistency: The jet dyeing system is equipped with a print head at the position corresponding to the threading hole, which can accurately spray the specified amount and color of dye according to the design requirements, ensuring the consistency and accuracy of dyeing. Whether observed from close or far distance, the dyed yarn can show a natural and harmonious gradient effect.

[0022] 5. Ease of operation: The operation method of the present invention is simple and easy. You only need to replace the traditional wire collecting plate with the wire collecting plate with the spray dyeing system of the present invention or directly connect the printing bracket to the traditional wire collecting plate, and correctly connect the control terminal to pass the yarn according to the traditional process requirements. The entire spray dyeing operation realizes automated production and reduces the difficulty of operation.

[0023] In summary, the present invention not only simplifies the production process and reduces the cost, but also improves the environmental protection and market competitiveness of the product, and provides a new dyeing solution for the textile industry. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will describe the implementation methods of the present invention in detail with reference to the accompanying drawings and embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. It should be noted that as long as there is no conflict, the various embodiments of the present invention and the various features in the embodiments can be combined with each other, and the technical solutions formed are all within the protection scope of the present invention.

[0028] Meanwhile, in the following description, many specific details are set forth for the purpose of explanation to provide a thorough understanding of the embodiments of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without the specific details or the specific manner described herein.

[0029] [A yarn collection system with inkjet dyeing function provided by the present invention] A yarn collecting system with inkjet dyeing function comprises a collecting plate 1, a dyeing system 2 and a dye bin 3. The collecting plate 1 is provided with a plurality of threading holes 4, which are equidistantly distributed. The dyeing system 2 comprises a control terminal 5, a print head 6 and a feed pipe 7. Each threading hole 4 is provided with at least one print head 6, and each of the print heads 6 is connected to the dye bin 3 via at least one feed pipe 7. The control terminal 5 is connected to each print head 6 and independently controls each print head 6 to perform the dyeing operation.

[0030] In order to better perform fine printing and prevent the print head 6 from sticking to the print head 6 during the inkjet printing process due to the fiber filaments floating in the air in the production environment, affecting the accuracy of the printed color, a plurality of wire collecting plates 1 with print heads 6 can be arranged in parallel to form a combination for coordinated inkjet printing operations. Each of the print heads 6 arranged on the wire threading hole 4 is only connected to a feed pipe 7 connected to the dye bin 3, and each wire collecting plate 1 is connected to a dye bin 3 of different color dyes, that is, all the print heads 6 on each wire collecting plate 1 only perform inkjet printing operations of the same color, and coordinated inkjet printing between multiple wire collecting plates 1 is required to make the yarn have rich colors.

[0031] For example, the CMYK color scheme currently used in the market, the wire collecting plate 1 with the print head 6 is arranged horizontally on four sides, and the positions of the wire threading holes 4 on the four wire collecting plates 1 correspond one to one, to ensure that the yarn can pass through all four wire collecting plates 1 straightly, and the print head 6 on each wire collecting plate 1 is uniformly connected to one of the colors in CMYK for spraying operations. For example, the wire collecting plate 1 closest to the textile equipment is the No. 4 wire collecting plate 1, then the print head 6 on the front end No. 1 wire collecting plate 1 is only responsible for the color spraying operation of the C (cyan) part, the print head 6 on the No. 2 wire collecting plate 1 is only responsible for the color spraying operation of the M (magenta) part, the print head 6 on the No. 3 wire collecting plate 1 is only responsible for the color spraying operation of the Y (yellow) part, and the print head 6 on the No. 4 wire collecting plate 1 is only responsible for the color spraying operation of the K (black) part. If a color other than the four colors is to be sprayed, multiple collecting plates 1 are required to cooperate in the spraying. For example, when a section of yarn needs to be sprayed green, the No. 1 collecting plate 1 and the No. 3 collecting plate 1 are required to cooperate in the spraying of the yarn section that needs to be sprayed green.

[0032] Similarly, in order to reduce the use of the wire collecting plate 1, the print head 6 can also be configured. The printing group 8 will replace each print head 6 set on the wire threading hole 4 with a printing group 8 composed of multiple laterally plugged print heads 6. Each print head 6 in the printing group 8 is connected to the dye bin 3 through a feed pipe 7. Each print head 6 is connected to the dye bin 3 of a different color dye, that is, each print head 6 in the printing group 8 only performs a spray-dyeing operation of one color, and the multiple print heads 6 in the printing group 8 need to cooperate in the spray-dyeing work to make the yarn have rich colors.

[0033] A waste collecting trough 9 is provided at the bottom of the threading holes 4 of the above three combinations, and a waste pipe 10 is connected to the tail end of the waste collecting trough 9 , and is connected to a waste bin 11 through the waste pipe 10 .

[0034] In order to be compatible with the existing wire collecting plate 1, the present technical solution proposes that a printing bracket 12 can be movably connected to the wire collecting plate 1, and the printing bracket 12 movably connected to the wire collecting plate 1 covers at least one area of ​​the wire collecting plate 1, and a front-to-back through-spraying channel 13 is provided at a position corresponding to each wire threading hole 4 of the wire collecting plate 1, and each spraying channel 13 is provided with at least one print head 6, and each print head 6 is connected to the dye bin 3 via at least one feed pipe 7, and the print heads 6 are connected to the control terminal 5.

[0035] In order to prevent the print head 6 from being stuck to the print head 6 and affecting the accuracy of the printed color due to the fiber filaments floating in the air in the production environment during the inkjet printing process, the print head 6 on the printing bracket 12 can also be formed by multiple print heads 6 being horizontally plugged into a printing group 8.

[0036] In order to facilitate the collection of waste ink, a waste collection groove 9 is provided at the bottom of the spraying channel 13 of the printing bracket 12. The waste collection groove 9 is connected and penetrated inside the printing bracket 12, and is connected and penetrated at the bottom of the printing bracket 12, and is connected to the waste bin 11 through the waste pipe 10 at the bottom of the printing bracket 12.

[0037] In order to improve the uniformity of spraying, three print heads 6 or print groups 8 are arranged on each wire threading hole 4 or each spraying channel 13 of the printing support 12, and are distributed in an isosceles triangle around the center point.

[0038] In order to improve the color fixing effect, a color fixing device 14 may be further provided at the rear end of the spray dyeing system 2. The color fixing device 14 is a heat drying device and / or an air drying device.

[0039] [Operation method of a yarn collection system with inkjet dyeing function provided by the present invention] An operating method of a yarn collecting system with inkjet dyeing function: S1: Set the yarn collecting plate 1 between the yarn source (such as the yarn frame of the warp knitting machine) and the textile equipment, and connect the print head 6 or the print group 8 set on the threading hole 4 or the printing support 12 spraying channel 13 to the dye bin 3 through the feed pipe 7; connect the waste collection tank 9 to the waste bin 11 through the waste pipe 10, open the control terminal 5, and connect it to the spraying system 2; S2: Pass the yarn through the threading hole 4 of the thread collecting plate 1 according to the design and connect it to the textile equipment so that each yarn corresponds to a printing head 6 or a printing group 8; S3: Input the designed inkjet pattern file into the control terminal 5, start the textile equipment, and the textile equipment controls the yarn traction mechanism to pull the yarn forward; the control terminal 5 controls the dye bin 3 to transport the dye to the print head 6 or the printing group 8 through the feed pipe 7, and the control terminal 5 controls the print head 6 or the printing group 8 to perform precise inkjet dyeing operations according to the designed inkjet pattern, so that the yarn is spray-dyed with the specified color according to the design. Example

[0040] Reference Figure 1 , a yarn collecting system with inkjet dyeing function. The embodiments of the present application all take a creel-type warp knitting machine as the application scenario, and the inkjet solution is carried out based on the existing CMYK color matching solution.

Example

[0042] Reference Figure 2 On the basis of Example 1, in order to more accurately control the inkjet printing accuracy of the print head 6 and prevent the occurrence of color bleeding due to the contamination of the print head 6 caused by the stickiness of fiber micro-flocculation floating in the air in the actual environment, four wire collecting plates 1 can be used to independently control one color of CMYK for inkjet printing, and the print head 6 on each wire collecting plate 1 is only connected to one feed pipe 7 which is separately connected to one of the CMYK dye bins 3. When special color dyes are needed, the wire collecting plate 1 can also be added accordingly according to actual conditions; a color fixing device 14 is also provided at the rear end of the wire collecting plate 1 along the yarn travel direction. The color fixing device 14 can be a thermal drying device or an air drying device according to the actual production environment. When the yarn travels a short distance, it is recommended to use thermal drying equipment and air drying equipment at the same time. Example

[0043] Reference Figure 3On the basis of Example 1, in order to more accurately control the inkjet printing accuracy of the print head 6 and prevent the occurrence of color bleeding due to the stickiness of fiber micro-flocculation floating in the air in the actual environment, four print heads 6 can be used to form a printing group 8. Each print head 6 in the printing group 8 independently controls one color of CMYK for inkjet printing and each print head 6 is only connected to one feed pipe 7 that is separately connected to one of the CMYK dye bins 3. The shell of the print head 6 has a serial interface, which is convenient for adding or subtracting the print head 6 when the operation color dye needs to be increased or decreased. Example

[0044] Reference Figure 4 On the basis of Example 1, in order to facilitate the integration of the yarn collection system with inkjet dyeing function of the present application into the existing traditional collection board 1 for operation, the present application sets the dyeing system 2 in the printing bracket 12 which can be flexibly installed on the collection board 1, and the printing bracket 12 covers at least one area in the collection board 1. In this embodiment, the longitudinal printing bracket 12 is preferably used, that is, each printing bracket 12 longitudinally covers a longitudinal row of wire holes 4 of the collection board 1. The printing bracket 12 is provided with a front-to-back through-dyeing channel 13 at the position corresponding to each wire hole 4, so that the yarn can pass through the corresponding wire hole 4 and the dyeing channel 13, the print head 6 or the printing group 8 is arranged on the dyeing channel 13, and the bottom end of the dyeing channel 13 is also provided with a waste collection groove 9, the waste collection groove 9 in the printing bracket 12 connects and penetrates the waste collection groove 9 from top to bottom, and is connected to the waste pipe 10 at the bottom of the printing bracket 12, and the printing bracket 12 is connected to the waste bin 11 through the waste pipe 10. Example

[0045] Reference Figure 5 On the basis of the above embodiments, in order to make the spraying more uniform, the print heads 6 or print groups 8 arranged on the threading hole 4 or the spraying channel 13 of the printing support 12 can be arranged in groups of three in an isosceles triangle. That is, assuming that the threading hole 4 uses the print head 6 for spraying printing, in order to spray more uniformly, three print heads 6 are arranged in an isosceles triangle around the threading hole 4 to spray the yarn with the same color at the same time; assuming that the printing support 12 uses the print group 8 for spraying printing, in order to spray more uniformly, three print groups 8 are arranged in an isosceles triangle around the threading hole 4 to spray the yarn with a uniform color at the same time, and the spraying channel 13 on the corresponding printing support 12 also uses the same setting. Example

[0046] Reference Figure 6 , an operation method of a yarn collecting system with inkjet dyeing function, specifically: Step S1: The yarn collecting plate 1 is arranged between the yarn frame and the warp knitting machine, and the print head 6 is connected to the control terminal 5, the dye bin 3 and the waste bin 11 respectively.

[0047] Specifically, the wire collecting plate 1 is first fixed on the bracket between the creel and the warp knitting machine to ensure that the wire collecting plate 1 is stable and does not shake. The height of the wire 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 will not produce a drastic change in tension when passing through the spray dyeing system 2 of the wire collecting plate 1.

[0048] The print head 6 or print group 8 arranged on the wire collecting plate 1 or the printing bracket 12 is connected to the dye bin 3 through the feed pipe 7 and is connected to the control terminal 5 integrated on the warp knitting machine through the circuit. The waste ink collection tank arranged on the inkjet system 2 is connected to the waste bin 11 through the waste pipe 10.

[0049] Step S2: The yarn is passed through the threading hole 4 of the thread collecting plate 1 and connected to the warp knitting machine according to design requirements, so that each yarn corresponds to a printing head 6 or a printing group 8.

[0050] Specifically, the yarn is passed through the corresponding designated threading holes 4 of the wire collecting plate 1 in sequence according to the needs of the weaving design and connected to the corresponding weaving needle positions of the warp knitting machine, so that the control terminal 5 can accurately spray the corresponding color on the yarn at the corresponding position during the spray-dyeing operation.

[0051] Step S3: Turn on the warp knitting machine, and the traction mechanism of the warp knitting machine pulls the yarn forward to perform weaving operations; the control terminal 5 controls the dye bin 3 to output a specified amount and color of dye according to a preset spraying scheme, and transports the dye to the print head 6 or the printing group 8 through the feed pipe 7 to inkjet dye the yarn, so that the yarn is spray-dyed with the specified color according to the design.

[0052] 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 and tension of the yarn. The running speed of the yarn should match the spraying speed. Then the control terminal 5 is turned on, and the preset spraying scheme is loaded. The spraying scheme includes the spraying color parameters of each yarn, the injection amount of the dye, the injection time and other parameters. Then the warp knitting machine is started, and the traction mechanism of the warp knitting machine begins to pull the yarn forward. At the same time, the control terminal 5 begins to control the dye bin 3 to output the specified number and color of dye according to the preset spraying scheme, and the dye is transported to the print head 6 through the feed pipe 7. According to the instructions of the control terminal 5, the print head 6 sprays the dye when the yarn passes by, and sprays the dye onto the yarn. The injection amount and injection time of the dye are accurately controlled by the control system according to the preset spraying scheme to ensure that each yarn can be dyed into the specified color. After the dyeing is completed, the yarn continues to move forward, passes through the color fixing device 14 for color fixing treatment, and is then pulled to the needle bed by the warp knitting machine for weaving.

[0053] Those skilled in the art should be clearly aware that the embodiments in the present application are only for a more complete and comprehensive display of all the technical elements of the present application. However, in actual use, due to the small size of the print head 6 and the precise control of the dye output by the control terminal 5, basically no dye scattered outside the yarn will be generated. Therefore, the waste pipe 10 and the waste bin 11 are non-essential technical features. They appear in the embodiments only to show the safest solution. Therefore, the yarn collection system with inkjet dyeing function that does not use the waste pipe 10 and the waste bin 11 is also within the protection scope of the present application.

[0054] The present invention and its embodiments are described schematically above, and the description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by it and designs a structural method and an embodiment similar to the technical solution without creativity without departing from the purpose of the invention, they shall all fall within the protection scope of the present invention.
