Description

Technical Field

[0001] The invention relates to the technical field of yarn dyeing and finishing, in particular to a single yarn dyeing and finishing device. Background Art

[0002] Yarn dyeing usually adopts the yarn aggregate dyeing method, which is further subdivided into cheese dyeing, warp beam dyeing and hank dyeing.

[0003] Among them, cheese dyeing is a more commonly used method for dyeing yarn aggregates, and its process flow includes: raw yarn, loose winding, chamfering, yarn loading, pretreatment, dyeing, dehydration, drying, winding, and packaging. Cheese pretreatment and cheese dyeing are to wind the yarn on a perforated bobbin according to a certain density to form loose yarn, and then put the loose yarn into a cylinder, inject working fluid, seal it, increase temperature and pressurize it for operation. The following technical defects exist in the actual production process: vat dyeing is an intermittent production due to its sealed operation, and its efficiency is low. In addition, during the operation, as the working liquid is consumed, the concentration of dyes or auxiliaries gradually decreases, which can easily cause inconsistent reactions of the working liquid from beginning to end; the steric hindrance between yarns and the air layer between yarns will hinder the infiltration of the working liquid, which will also lead to inconsistent reaction probability and rate, resulting in differences in dyeing and finishing quality; in order to allow the working liquid to penetrate the entire cheese yarn layer, the pressure of the working liquid needs to be reasonably adjusted. If the pressure is too small, it is difficult for the working liquid to penetrate the entire cheese yarn layer. If the pressure is too large, the yarn layer will be disturbed, and the dyeing quality is difficult to guarantee; due to the steric hindrance between the cheese yarn layers, in addition to making it difficult for the working liquid to penetrate, it takes a long time, and the washing, dehydration and drying burdens are heavy, part of the working liquid will be intercepted, which not only increases the ineffective consumption of the working liquid and energy consumption, but also increases the workload of washing, dehydration and drying, resulting in high water consumption and energy consumption; cheese yarn is dyed in one vat with one color, and it is difficult to achieve colorful coloring.

[0004] Warp beam dyeing is a process in which the raw yarn is wound around a perforated coil by a loose warping machine to form a loose warp beam, which is then mounted on the yarn carrier of the dyeing machine and placed in the warp beam dyeing machine. A pump is used under high temperature and high pressure conditions to completely penetrate the rolled yarn with the dye liquid. Its technical defects are similar to those of cheese yarn dyeing.

[0005] Hank dyeing is to reel the yarn on a reel to form a hank, then dye it, steam it, wash it with water, dry it, and finally wind the hank to form a cheese yarn. Its technical defects are that it cannot be mass-produced on a large scale, the yarn batches vary greatly, it is easy to have color changes, it consumes a lot, it has serious strength damage, it has a narrow range of application, and the final feel of the fabric is poor.

[0006] In order to solve the technical problems existing in the above-mentioned yarn aggregate dyeing method, the relevant technology provides a series of single yarn dyeing and finishing methods. For example, Chinese patents CN201811644160.4 and CN201910857266.0 proposed a single yarn dip dyeing and winding process, CN200410028019.3 and CN202110715238.2 proposed a single yarn local spray dyeing process, CN201410189024.6 and CN202010656914.9 proposed a single yarn spray dyeing and drying process, CN202110396082.6 and the like proposed a single yarn dip dyeing, drying and winding process, CN202110424932.9 proposed a single yarn pad dyeing, drying and winding process, CN202010227256.1 proposed spray dyeing, steaming and drying processes, and CN202211368845.7 proposed single yarn sizing, drying, warping and steaming processes.

[0007] In the process of implementing the relevant technology, the inventors found that the above technical solution has the following technical problems: 1. The yarn is stretched and tightened. After dyeing, the yarn needs steaming or drying time to fix the color. If the yarn is stretched and tightened at high speed, the drying equipment and steaming equipment will be bulky, with low energy utilization, large investment and high operating costs. During the stretching and tightening process, the yarn is stretched and traction and friction increases, resulting in yarn strength loss and serious pilling.

[0008] 2. Dyeing method. Whether it is immersion dyeing or pad dyeing, as the dyeing proceeds, the concentration of each component of the dye solution will inevitably change, affecting the dyeing process and dyeing quality. The atomization device in spray dyeing has a complex structure, high energy consumption, poor permeability, and can only dye the surface, which is not suitable for yarn dyeing.

[0009] 3. Washing problems. When the yarn is stretched and run at high speed, the contact time between the yarn and the washing liquid is short, and the unfixed dyes in the yarn do not have sufficient time to be dissolved into the washing liquid, resulting in poor washing effect and efficiency, and high water consumption; when the yarn is stretched and run at low speed, the washing efficiency is low, which also causes high water consumption; the dyes and additives in the washing waste liquid are difficult to separate.

[0010] 4. The washing, steaming and drying devices in the dyeing and finishing equipment are independent of each other, and the utilization rates of water and heat energy are not high, resulting in a considerable amount of water and heat energy not being fully utilized and being discharged.

Figure 5 This is a partial schematic diagram of the water retaining trough device. Figure 6 This is a schematic diagram of the device of the second drying component.

[0042] In order to better illustrate the embodiment of the present invention, the working principle of the single yarn dyeing and finishing device provided by the present invention is shown as follows: After the yarn 200 is unwound from the original yarn bobbin 100, it is led to the yarn channel 310 of the multi-pass dyeing and finishing tube 300 through a series of yarn guide devices and redirected. The working liquid in the working liquid tank 340 is introduced into each liquid supply channel 320 on the side of the yarn channel 310 by the precision peristaltic pump 330, and each liquid supply channel 320 performs fine dyeing and finishing on the yarn 200 in the yarn channel 310. Then, the dyed and finished yarn 200 is input into the conveying assembly from the upper funnel unit 350, and is sent into the swinging device 430 by the overfeeding roller 420 for swinging treatment, and then is arranged in a single circle on the yarn carrier in a relaxed state. The yarn 200 is transported to the first drying channel 510 of the first box 500 after being fixed by the yarn-carrying mesh belt 400 and fixed by the yarn-fixing mesh belt 410. After the first heating devices 520 on the periphery of the first drying channel 510 generate heat and perform the first drying treatment on the yarn 200 in the first drying channel 510, the yarn 200 is output from the yarn delivery outlet at the bottom of the first drying channel 510 and enters the second box 600 under the joint fixed transportation of the yarn-carrying mesh belt 400 and the yarn delivery inlet, and enters the steaming cavity 610, and is heated by the second heating device 650 in the steaming cavity 610 and the steam generating device 640. After the steaming treatment, the yarn 200 is continuously transported by the yarn-carrying mesh belt 400 and the yarn-fixing mesh belt 410, and then outputted from the yarn delivery outlet below the steaming chamber 610 into the third box 700, and then enters the immersion tank 710 through the yarn delivery inlet; the immersion liquid in the immersion tank 710 fully immerses the yarn 200 under the action of the fourth heating device 730, and then the yarn 200 is outputted from the yarn delivery outlet above the immersion tank 710, and enters the water washing chamber 720 through the yarn delivery inlet below the water washing chamber 720; the yarn 200 in the water washing chamber 720 is transported from bottom to top in sequence under the transporting action of the transport unit. After passing through the upward Z-shaped water retaining grooves 740 and being washed by the washing liquid sprayed by the spray devices 750 during the transportation process, the yarn is output from the yarn delivery outlet above the water washing chamber 720 and enters the second drying channel 810 of the second drying component. After the fifth heating devices 820 on the periphery of the second drying channel 810 generate heat and perform a second drying treatment on the yarn 200 in the second drying channel 810, it is sent to the winding component under the fixed transportation of the yarn carrying mesh belt 400 and the fixed yarn mesh belt 410, and then under the winding action of the winding device 910, the yarn 200 is wound onto the yarn drum 900.

[0043] By adopting the single yarn dyeing and finishing device provided by the present invention to dye and finish the yarn, the following technical effects can be achieved: 1) Reduce energy consumption and improve the drying and steaming quality of yarn. Since the first water flow interlayer 530, the second water flow interlayer 620 and the immersion tank 710 are interconnected, the heat energy generated by the first heating device 520, the second heating device 650 and the steam generating device 640 can realize their corresponding drying, heating and steaming functions. The inner walls of the first box 500 and the second box 600 will also absorb the heat energy and transfer the heat energy into the water flow in the first water flow interlayer 530 and the second water flow interlayer 620 of the inner wall, and then the water flow carrying the heat energy is brought into the immersion tank 710 to irrigate the yarn. The yarn is immersed in water, thereby realizing the recycling of heat energy; further, since the water flow in the first water flow interlayer 530 and the second water flow interlayer 620 has a large specific heat, it stores heat energy and also reversely heats the first drying channel 510 and the steaming cavity 610 in the first box 500 and the second box 600, which can further reduce the energy consumption required for the first heating device 520, the second heating device 650, the steam generating device 640, the third heating device 641, and the fourth heating device 730 to maintain normal operation. In addition, the yarn is arranged in a single circle on the surface of the yarn-carrying mesh belt 400 in a relaxed state under the action of the yarn swinging device 430, which is easy for heat to enter and water to evaporate, and the drying rate is high; when the water level in the immersion tank 710 in the water washing component is higher than the yarn conveying outlet of the steaming cavity 610, a water seal can be formed on the steaming cavity to reduce the loss of heat energy and steam.

[0044] 2) While saving water resources for dyeing and finishing, the washing efficiency of the yarn is improved. Under the action of the yarn swing device 430, the yarn is arranged in a single circle on the surface of the yarn-carrying mesh belt 400 in a relaxed state, and the washing liquid can more easily enter the interior of the yarn, thereby decomposing the unfixed dye into the washing liquid and washing it out of the yarn, so that the washing efficiency of the yarn is higher; in addition, since the immersion tank 710 is connected to the steam chamber 610, the steam escaping from the steam chamber 610 or the condensed water generated flows back into the immersion tank 710 to play a washing role, thereby improving the utilization efficiency of water energy and increasing the washing effect; due to the upward Z-shaped water retaining groove 740, the liquid spraying device 7 After the washing liquid sprayed out from 50 rinses the yarn layer between the yarn-carrying mesh belt 400 and the fixed yarn mesh belt 410, the washing liquid is concentrated in the water retaining groove 740 and flows downward along the bottom plate of the water retaining groove 740, running opposite to the conveying unit, which can further rinse the subsequent yarn and improve the washing efficiency; the washing liquid flowing out from the upper water retaining groove 740 flows into the immersion groove 710 below, and can continue to be used for immersion washing of the yarn layer. In the above process, the washing liquid is rinsed, rinsed, and immersed in water, which can greatly increase the contact time between the washing liquid and the yarn, and further improve the washing efficiency.

[0045] 3) Water-heat internal circulation to achieve effective separation of dye auxiliaries and water. The water-washing waste liquid generated by the water-washing component is discharged into the steam generating chamber 640 through a valve, and steam is generated by heating to achieve effective separation of water and dyes, auxiliaries, salts and other dyeing and finishing agents. At the same time, the steam generated in the steam generating chamber 640 generates condensed water after steaming and flows back into the water-washing component for water washing. The water-washing waste liquid generated after the water washing operation repeats the above steaming, condensing and water-washing internal circulation operations, which not only saves a lot of water and heat resources, but also achieves effective separation of dyes, auxiliaries and water.

[0046] 4) Large-capacity, fast, continuous and efficient operation, wide applicability. Loose yarn stacking operation is conducive to increasing the yarn capacity per unit operating space, fully functioning, and fast and efficient operation. It also avoids problems such as yarn strength damage, pilling, etc. caused by tight and fast yarn operation, and is suitable for all kinds of yarns.
