Description

Technical Field

[0001] The invention relates to the technical field of yarn dyeing, in particular to a multi-component blended yarn jet dyeing device and a dyeing process thereof. Background Art

[0002] In recent years, the application field of fancy yarns has gradually expanded, and unique and high-end fancy yarn products on the market are changing with each passing day, such as coated bamboo yarn, sprayed wool belt yarn, high-count napped yarn, etc., which have broad application prospects. Multi-component fancy yarns are mainly viscose-covered polyester core-spun yarns, using high-strength and low-stretch polyester filaments, and covered with viscose fibers. There are even three kinds of yarns for combined core-spun, such as nylon, wool, and cotton. The core yarns are basically based on polyester core-spun, which are spun by spinning machines with certain technological content. They have the uniformity of filament yarns and the natural hairiness of short fibers. Some of them are as light as silk after weaving, and feel smooth. It can be basically consistent with the style of cotton clothing fabrics. Since the core yarns are mainly polyester, they have high strength, and their strength index is 40% to 60% higher than that of cotton yarns. They are uniform in yarn and the best yarn for non-ironing clothing. However, it is very difficult to dye multi-component cored wire. After repeated practice and research, effective exploration has been carried out in the selection of dyes, optimization of dyeing process, reproducibility of small samples to large samples, color difference and color flowers, and washboard marks after dyeing, and some good results have been achieved. However, it still has the following disadvantages: when dyeing multiple groups of yarns, the traditional immersion dyeing method is not uniform enough, resulting in incomplete internal coloring.

After a certain period of time, the dye in the dye shell 1 becomes more and more. At this time, the circulation pump 41 can be turned on to pump the dye in the dye shell 1 into the feed pipe 43, and then the feed pipe 43 circulates the dye into the dye tank 35 again.

[0026] 5. The yarn transmission mechanism 5 is arranged inside the dyeing material shell 1. The yarn transmission mechanism 5 includes a yarn roller 51. A main shaft 53 is fixedly passed through the yarn roller 51. A clamping rod 59 is fixed at both ends of the main shaft 53. A mounting shell 52 is arranged at both ends of the clamping rod 59. The mounting shell 52 is fixed on the outer wall of the dyeing material shell 1. An adjusting groove 54 is penetrated through the mounting shell 52. A limited stopper 55 is connected to the side of the mounting shell 52 away from the dyeing material shell 1 by bolts. A No. 1 motor 57 is installed on the top of the mounting shell 52. A No. 1 screw rod 56 is fixed at the output end of the No. 1 motor 57. The No. 1 screw rod 56 movably passes through the mounting shell 52. One end of the No. 1 screw rod 56 arranged inside the adjusting groove 54 is rotatably connected to the inner wall of the adjusting groove 54. A mounting member 58 is arranged on the part of the No. 1 screw rod 56 arranged inside the adjusting groove 54. The clamping rod 59 is correspondingly clamped in the mounting member 58. During use, the connection of the adjustment groove 54 can be maintained by removing the limit baffle 55. At this time, the height adjustment of the mounting member 58 can be achieved by rotating the No. 1 screw rod 56. After ensuring that the height of the mounting member 58 is aligned, the yarn roller 51 and the main shaft 53 can be installed.

[0027] The mounting member 58 comprises a sliding block 581, a movable rod 582 is horizontally passed through the sliding block 581, an adjustment plate 583 and a mounting block 585 are respectively fixed at both ends of the movable rod 582, a hand-held plate 584 is fixed on the outer side of the adjustment plate 583, a clamping groove 586 is provided on the side of the mounting block 585 away from the sliding block 581, the clamping groove 586 is correspondingly clamped with the clamping rod 59, and a spring 587 is sleeved on the movable rod 582 between the sliding block 581 and the mounting block 585; During use, after the height of the mounting piece 58 is aligned, the movable rod 582 can be pulled by the hand-held plate 584 to increase the distance between the mounting blocks 585, and the connecting rod 59 can be placed between two slots 586 in the same horizontal plane. Then, the hand-held plate 584 is released, so that the movable rod 582 returns to its original position under the elastic force of the spring 587, driving the mounting blocks 585 to approach each other, and connecting the connecting rod 59 between the slots 586, completing the fixation of the yarn roller 51 and the main shaft 53. At this time, the up and down movement of the mounting piece 58 can drive the movement of the entire yarn roller 51, thereby realizing the winding of the yarn for easy dyeing.

[0028] In the above embodiment, the spray-dyeing mechanism 3 is used to perform high-pressure spray-dyeing on multiple groups of yarns. The dye is sprayed onto the yarn at high speed through high pressure, so that the dye quickly penetrates the interior of the fiber, achieving a fast and uniform dyeing effect. The dyeing of multiple groups of yarns is undoubtedly more efficient and more uniform. During the spray-dyeing process, excess dye falls into the dye shell 1 and is recycled and reused by the circulation mechanism 4, effectively reducing the cost of the dyeing process. The design of the mounting member 58 facilitates the installation and disassembly of the entire yarn transmission mechanism 5, which is conducive to daily maintenance and yarn replacement.

[0029] Example 2 like Figure 5-11 As shown, a tension adjustment mechanism 6 is provided between one of the yarn transmission mechanisms 5 and the dye shell 1, and the tension adjustment mechanism 6 includes a bracket 61, the bracket 61 is fixed on the top of the dye shell 1, and an adjusting roller 62 is provided directly below the bracket 61, and side plates 63 are fixed on both sides of the adjusting roller 62, and guide rods 64 and second screw rods 65 are correspondingly inserted on the side plates 63 on both sides of the adjusting roller 62, the bottom of the guide rod 64 is fixed on the dye shell 1 and the guide rod 64 is movably inserted on the side plate 63, and a limit plate is provided on the top of the guide rod 64, the side plate 63 is threadedly inserted on the side plate 63 and the bottom is rotatably connected to the dye shell 1, the top of the side plate 63 passes through the bracket 61 and is fixed with a second motor 66, and the second motor 66 is installed on the bracket 61; During use, by turning on different No. 2 motors 66, the corresponding No. 2 screw rods 65 are driven to rotate, thereby achieving height adjustment of the adjusting roller 62, thereby compacting and loosening the yarn, completing the tension adjustment of the corresponding yarn, and avoiding the problem of affecting the remaining yarns due to the overall adjustment.

[0030] The number and position of the adjusting rollers 62 correspond to those of the yarn rollers 51, and the end surfaces of the adjusting rollers 62 and the yarn rollers 51 are provided with wire-binding grooves; By means of the provided bundle groove, the yarn is transmitted in the bundle groove during yarn winding, thereby preventing the yarn from being derailed from the yarn roller 51 and the adjusting roller 62 due to horizontal movement during the transmission process.

[0031] An auxiliary mechanism 7 is arranged between the yarn transmission mechanisms 5, and the auxiliary mechanism 7 comprises an inner shell 71, the inner shell 71 is fixed on the inner wall of the dye shell 1, a through groove 72 is formed through the bottom of the inner shell 71, a partition 73 is fixed between the through grooves 72, the bottom of the partition 73 is fixed on the dye shell 1, a wire binding mechanism 75 is arranged on one side of the partition 73, a door groove 76 is formed on the top of the inner shell 71, a groove 77 is formed on the door groove 76, and a sealing member 74 is arranged on the groove 77; The sealing member 74 includes a sealing door 741, one end of which is arc-shaped, and both sides of one end of the sealing door 741 are movably arranged on the door groove 76, and a movable groove 78 for the movement of the sealing door 741 is provided on the groove 77. A mounting seat 744 is provided on the top of the sealing door 741, and a movable shaft 745 is movably connected between the inner walls of the mounting seat 744, and a movable block 746 is fixed on the movable shaft 745, and a movable ball 747 is movably inserted on the movable block 746, and a connecting rod 743 is fixed to the other end of the movable ball 747, and an electric telescopic rod 742 is fixed to the end of the connecting rod 743 away from the movable ball 747, and the electric telescopic rod 742 is fixed to the mounting plate 2; The wire harness mechanism 75 is provided with two groups and is located directly below the dye tank 35. The wire harness mechanism 75 includes an electric push rod 751 and a wire harness plate 752 fixed to the output end of the electric push rod 751. The electric push rod 751 is fixed on the inner wall of the inner shell 71. During use, the design of the electric telescopic rod 742 and other structures can facilitate the opening of the corresponding sealing door 741. Specifically, by starting the electric telescopic rod 742, the connecting rod 743 is driven to extend and retract, and the movable ball 747 at one end of the connecting rod 743 is correspondingly rotatably connected with the movable block 746, so that the sealing door 741 can be rotated around one end thereof, thereby rotating the sealing door 741 to penetrate the dyeing condition of the yarn inside the inner shell 71; The design of the wire bundling mechanism 75 can monitor the looseness of the yarn at all times through the distance sensor. If the yarn becomes loose, it means that the position of part of the yarn from the distance sensor has changed. At this time, the electric push rod 751 will be started accordingly to drive the wire bundling plate 752 to move, thereby completing the adjustment of the looseness of the yarn.

[0032] The dye tank 35 is fixed to the sealing door 741 in the middle, and the sealing doors 741 on both sides of the dye tank 35 are respectively provided with a pretreatment mechanism 8 and a drying mechanism 9; The pretreatment mechanism 8 includes a plunger pump 81 and a material box 82 installed on the top of the plunger pump 81, and the bottom of the plunger pump 81 is fixedly connected to a spray plate 83; The drying mechanism 9 includes a hot air blower 91 and an air duct 92 connected to the output end of the hot air blower 91 . The air duct 92 is fixedly passed through the sealing door 741 and is connected to a blast plate 93 .

[0033] In the above embodiment, the design of the tension adjustment mechanism 6 can accurately adjust the tension of the yarn to avoid affecting the spray dyeing effect of the yarn due to different yarn tensions. Secondly, the design of the pretreatment mechanism 8 and the drying mechanism 9 can pretreat the yarn and dry and solidify it after dyeing to avoid color difference in dyeing.

[0034] Example 3 like Figure 1-11 As shown, in the present invention, an electric heating plate is correspondingly arranged on the inner wall of the inner shell 71 to adjust the temperature inside the inner shell 71 to achieve a better dyeing process. The specific dyeing process flow is as follows: The yarn is passed through the tension adjustment mechanism 6 and the two yarn transmission mechanisms 5 in sequence, and the yarn can be transmitted on the yarn roller 51 and the adjustment roller 62. The specific installation is as follows: by removing the limit baffle 55, the connection of the adjustment slot 54 can be maintained. At this time, the height adjustment of the mounting member 58 can be achieved by rotating the No. 1 screw rod 56. After ensuring that the height of the mounting member 58 is aligned, when the height of the mounting member 58 is aligned, at this time, the movable rod 582 can be pulled by the hand-held plate 584 to increase the distance between the mounting blocks 585, and the clamping rod 59 is placed between the two clamping slots 586 in the same horizontal plane. Then, the hand-held plate 584 is released, so that the movable rod 582 returns to its original position under the elastic force of the spring 587, driving the mounting blocks 585 to move closer to each other, and the clamping rod 5 9 is connected between the card slots 586 to complete the fixation of the yarn roller 51 and the main shaft 53. At this time, the up and down movement of the mounting part 58 can drive the movement of the entire yarn roller 51, so as to realize the winding of the yarn. During the winding process, the yarn should be selected to pass through the bottom of 62 and the top of 51 in turn, and the winding of the yarn is completed by alternating winding. During the transmission process, the yarn first passes directly under the pretreatment mechanism 8. At this time, the alkali and refining agent in the pretreatment mechanism 8 are used to pretreat the yarn to achieve the effect of removing oil, impurities and 98°C elasticity. During the treatment process, the insulation time of the electric heating plate in the inner shell 71 is controlled to be extended to 60 minutes, which can effectively ensure that the elastic force of the yarn is slowly and evenly released under high temperature conditions, thereby reducing the washboard marks and color difference quality problems. At the same time, it contains wool, velvet, and acrylic fiber core-spun yarn, and the treatment temperature is maintained at a maximum of 75 degrees; Afterwards, the yarn passes directly under the nozzle 34. At this time, the high-pressure pump 31 is started to pump the dye in the dye tank 35 into the output pipe 33, and then it is sprayed out at high speed through the nozzle 34, and the yarn directly under the nozzle 34 is subjected to high-pressure jet dyeing treatment. The dye sprayed out by the nozzle 34 at high pressure partially falls into the dye shell 1. After a certain period of time, the dye in the dye shell 1 becomes more and more. At this time, the circulation pump 41 can be started to pump the dye in the dye shell 1 into the feed pipe 43, and then the feed pipe 43 is circulated and input into the dye tank 35 again. Due to the provision of the partition 73, the waste liquid and impurities generated by the pretreatment will not be mixed with the excess dye in the spray dyeing process; After the dyeing process is completed, the yarn passes directly under the drying mechanism 9. At this time, the hot air blower 91 is turned on to generate hot air, which is transported by the air duct 92 to the blast plate 93 and blown out to dry and solidify the yarn, thus completing the yarn processing. For core-spun yarn dyeing polyester (wool, velvet, acrylic) process (medium and dark colors): the heating rate from 40 to 60°C is 2°C / min, and the heating rate from 60 to 98°C is 1°C / min. The glass transition temperature of polyester is generally 90°C. By using modified polyester as the raw material, it can be slowly colored at 60 degrees. In order to ensure quality and avoid color spots caused by fast coloring, the dyeing process requires that the temperature be slowly increased from 60°C to achieve slow dyeing under low temperature conditions. The pH value of 4-5 is the best coloring value for polyester. Medium and dark colors require 70 degrees reduction treatment to ensure the color fastness of nylon. Core-spun yarn dyeing and polyester process (light color series): the heating rate from 40 to 60°C is 2°C / min, and the heating rate from 60 to 98°C is 1°C / min. No reduction is required after dyeing, and the dyeing and washing can be directly dyed with viscose.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
