Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of alpaca hair dyeing, in particular to a dyeing device and process for improving the rubbing fastness of alpaca hair. BACKGROUND

[0002] Alpaca hair is a natural animal fiber derived from alpacas in South America, belonging to a kind of camelid fiber, mainly produced in Peru, Argentina and other places, with an average fineness of 22-30 microns, having a hollow medullary cavity structure, giving it lightness, high warmth retention, low allergenicity, anti-staining and wear resistance, etc. Dyeing rubbing fastness refers to the ability of a textile to resist color loss or transfer when subjected to external force rubbing, and is one of the core indicators for evaluating dyeing quality. Alpaca hair in nature lacks yellow, red, purple, blue, green, navy and other color shades, and needs to be dyed. Due to the difficulty of dyeing the coarse cavity fibers in alpaca hair, the rubbing fastness of medium and dark colors is extremely poor. The existing technology uses low-temperature dyeing and high-temperature fixing, cooperates with high-standard fastness dyes for alpaca hair dyeing, and adds dyeing auxiliaries that can open the scales of alpaca hair at low temperature, NA2SO4 auxiliaries to remove surface float color, and smoothing agents that can improve rubbing fastness, so that the rubbing fastness of alpaca dyeing products can pass the textile color fastness test and meet the standard of rubbing color fastness. Alpaca hair fiber has low natural crimping degree, and the fiber is flat and stacked after wetting, with relatively small fiber gap. Under wet conditions, the scale layer of alpaca hair fiber absorbs water and expands, further compressing the fiber gap. At the same time, the medullary cavity of the fiber forms an internal water column after absorbing water, temporarily "locking" the water, delaying the lateral diffusion of water flow between fibers, making it difficult for water flow to completely penetrate the fiber during dyeing, especially the water flow at the top of the dyeing cylinder, which is easy to form a "dead water zone". The water flow is poor, and the dye is only attached to the surface layer of the fiber, without sufficient diffusion to the scale layer and cortex layer. At the same time, the dye adsorption capacity of the top fiber is lower than that of the bottom, which is easy to form color difference. The color difference area has lower dye adsorption capacity, and the proportion of residual float color is higher, which reduces the dyeing rubbing fastness. Therefore, we propose a dyeing device and process for improving the rubbing fastness of alpaca hair. SUMMARY

[0019] The porous pipe 12 is fixedly installed with a liquid injection pipe 13 at the upper end, and the inner cylinder 14 is fixedly installed with an inner square clamping piece 17, which is sleeved on the liquid injection pipe 13. A square groove 18 is arranged between the inner wall of the inner square clamping piece 17 and the outer wall of the liquid injection pipe 13. The fixed plate 5 is provided with a rotating disc 7 for supporting the inner cylinder 14. A plurality of rolling balls 9 are arranged between the rotating disc 7 and the fixed plate 5. The lower end of the rotating disc 7 and the upper end of the fixed plate 5 are both provided with limiting grooves 8 for limiting the rolling balls 9. Four magnetic blocks 10 are fixedly installed on the rotating disc 7. The lower end of the inner cylinder 14 is provided with four clamping grooves 16 corresponding to the magnetic blocks 10. Four magnetic plates 11 magnetically attracted to the magnetic blocks 10 are fixedly installed on the fixed plate 5. The magnetic blocks 10, the clamping grooves 16 and the magnetic plates 11 are all arranged in a circumferential arrangement with an included angle of 90 degrees. The upper cover 2 is fixedly installed with a motor 27 at the top. The motor 27 stops and reverses regularly, and the rotation amplitude is a whole number each time. The motor 27 is fixedly installed with a rotating shaft 28 at the output end. The rotating shaft 28 is provided with a sleeve 32. The lower end of the sleeve 32 is provided with a square corresponding to the square groove 18. The rotating shaft 28 is fixedly installed with an electromagnetic strip 29 inside the lower end. The electromagnetic strip 29 generates a magnetic field when the motor 27 works. The lower end of the rotating shaft 28 is symmetrically and slidingly installed with two magnetic rods 30 magnetically repelled to the electromagnetic strip 29. The electromagnetic strip 29 and the two magnetic rods 30 are both fixedly connected with second springs 31. Two first spiral grooves 34 and two second spiral grooves 35 are arranged on the inner wall of the sleeve 32. The first and last opening angles of the two first spiral grooves 34 and the two second spiral grooves 35 are both 180 degrees. The rotation directions of the first spiral grooves 34 and the second spiral grooves 35 are opposite. The first end of each first spiral groove 34 coincides with the first end of one of the second spiral grooves 35, and the last end coincides with the last end of the other second spiral groove 35. Two sliding rods 38 for guiding the sleeve 32 are symmetrically and slidingly installed inside the sleeve 32. The sleeve 32 is fixedly connected with a third spring 33 between the upper end and the inner wall of the top of the upper cover 2. Two vertical grooves 40 for limiting the sliding rods 38 and an annular groove 41 are arranged inside the upper cover 2. The annular groove 41 is communicated with the bottoms of the two vertical grooves 40, and the depth of the annular groove 41 is greater than that of the vertical grooves 40. The two sliding rods 38 are respectively located at the last ends of the two first spiral grooves 34. Each sliding rod 38 is fixedly connected with a fourth spring 39 between the sleeve 32. A guide plate 36 for guiding the magnetic rod 30 is rotatably installed at the intersection of each first spiral groove 34 and second spiral groove 35. A baffle 37 for limiting the magnetic rod 30 is rotatably installed at the last end of each first spiral groove 34 and each second spiral groove 35. In the initial state, the motor 27 does not work, the electromagnetic strip 29 does not generate a magnetic field, the magnetic rods 30 are not subjected to magnetic repulsion, and the second springs 31 pull the magnetic rods 30 back to the rotating shaft 28. The sleeve 32 is pulled back to the upper cover 2 by the third spring 33. The two sliding rods 38 are located at the top of the corresponding vertical grooves 40. The motor 27 will start while the circulating pump 3 works. The electromagnetic strip 29 will be electrified and generate a magnetic repulsion to the magnetic rods 30.The magnetic rod 30 will move to the inner wall of the sleeve 32 against the elastic force of the second spring 31, and will be inserted into the first end of the corresponding first spiral groove 34. With the motor 27 driving the rotating shaft 28 to rotate forward, through the limiting of the vertical groove 40 to the slide rod 38, the sleeve 32 will first slide downward and be inserted into the square groove 18, at the same time, the magnetic rod 30 will move along the first spiral groove 34, and when passing through the intersection of the first spiral groove 34 and the second spiral groove 35, it will push the guide plate 36 to rotate into the second spiral groove 35, preventing the magnetic rod 30 from moving into the second spiral groove 35. When the magnetic rod 30 moves to the end of the first spiral groove 34, the slide rod 38 will move into the annular groove 41, at this time, the end of the magnetic rod 30 will push against one end of the slide rod 38, making the other end of the slide rod 38 extend and be inserted into the annular groove 41, preventing the elastic force of the third spring 33 from pulling the sleeve 32 to retract upward, at the same time, the corresponding baffle 37 limits the end of the magnetic rod 30, preventing the magnetic rod 30 from entering the second spiral groove 35, and making the magnetic rod 30 drive the sleeve 32 to rotate forward together, the sleeve 32 will drive the inner cylinder 14 to rotate forward together, preventing the dye liquid from always impacting a certain part of the fiber through the holes on the porous pipe 12, reducing the situation of fiber breakage and entanglement. When the motor 27 drives the rotating shaft 28 to rotate forward for a certain number of turns, it will stop timing, at this time, the electromagnetic strip 29 will not be energized to generate a magnetic field, the two magnetic rods 30 will retract into the rotating shaft 28, and the end of the slide rod 38 will not be limited, the elastic force of the fourth spring 39 will pull the slide rod 38 to retract into the sleeve 32 to the initial state. Since the rotating shaft 28 rotates for a full number of turns, the opening and closing angle of the first spiral groove 34 is 180 degrees, at this time, the slide rod 38 will be located at the communication between the vertical groove 40 and the annular groove 41, the elastic force of the third spring 33 will pull the sleeve 32 and the slide rod 38 to move upward and reset. Since the opening and closing angle of the first spiral groove 34 and the second spiral groove 35 is 180 degrees, the two first spiral grooves 34 are located on the same straight line, and the two second spiral grooves 35 are also located on the same straight line. After the sleeve 32 is reset, the ends of the two magnetic rods 30 will be aligned with the first ends of the two second spiral grooves 35, and then the motor 27 will drive the rotating shaft 28 to rotate reversely, the two magnetic rods 30 will be inserted into the corresponding first ends of the second spiral grooves 35 due to magnetic repulsion, and then with the reverse rotation of the rotating shaft 28, the two magnetic rods 30 will move along the corresponding second spiral grooves 35, which is the same as the forward rotation of the rotating shaft 28. The sleeve 32 will first move downward and be inserted into the square groove 18, and then drive the inner cylinder 14 to rotate reversely for a certain number of turns. With the continuous reverse rotation of the motor 27, the inner cylinder 14 will drive the fiber to rotate reversely for a certain number of turns, preventing the fiber from being continuously impacted in one direction, and also preventing the dye liquid in the dye vat 1 from always flowing in one direction, causing the fiber to be continuously washed in one direction and appear entangled and knotted. When the inner cylinder 14 rotates, the ball 9 can reduce the friction between the rotating disc 7 and the fixed plate 5, and through the limiting of the magnetic block 10 by the clamping groove 16, the rotating disc 7 will always rotate together with the inner cylinder 14. When the inner cylinder 14 is not installed, the magnetic block 10 will be attracted by the magnetic force of the magnetic plate 11, driving the rotating disc 7 to rotate, so that the magnetic block 10 is always aligned with the magnetic plate 11.Since the magnetic block 10 and the card slot 16 and the magnetic plate 11 are arranged in a circumferential arrangement with an included angle of 90 degrees, after the inner cylinder 14 is installed, the four card slots 16 will always be aligned with the four magnetic plates 11, facilitating the alignment of the four corners of the lower end of the sleeve 32 when inserted into the square slot 18.

[0020] A plurality of dye injection nozzles 43 are fixedly installed at the lower end of the upper cover 2, a plurality of liquid guide channels 42 are arranged in the upper cover 2, the liquid guide channels 42 correspond one-to-one to the dye injection nozzles 43, one end of each liquid guide channel 42 communicates with the sleeve 32, and the other end communicates with the corresponding dye injection nozzle 43. A plurality of liquid pushing plates 44 are slidingly installed in the upper cover 2, the liquid pushing plates 44 correspond one-to-one to the liquid guide channels 42, a wedge-shaped block 45 is fixedly installed at the upper end of each liquid pushing plate 44, and a fifth spring 47 is fixedly connected between each liquid pushing plate 44 and the inner wall of the upper cover 2. A plurality of wedge-shaped plates 46 that cooperate with the wedge-shaped blocks 45 are slidingly installed in the upper cover 2, the wedge-shaped plates 46 correspond one-to-one to the wedge-shaped blocks 45, and one end of each wedge-shaped plate 46 is located on the movement track of the sleeve 32. In the initial state, the third spring 33 pulls the sleeve 32 to retract into the upper cover 2, the upper end of the sleeve 32 is in contact with one side of the inclined surface of the wedge-shaped plate 46, the wedge-shaped plate 46 is pushed into the interior of the upper cover 2, and through the cooperation of the wedge-shaped plate 46 and the wedge-shaped block 45, the wedge-shaped block 45 drives the liquid pushing plate 44 to move downward, and the fifth spring 47 is stretched. When the sleeve 32 moves downward, the elastic force of the fifth spring 47 drives the wedge-shaped block 45 and the liquid pushing plate 44 to move upward, the end of the wedge-shaped plate 46 extends to the movement track of the sleeve 32, the dye in the multi-hole pipe 12 is injected into the sleeve 32 through the liquid injection pipe 13, and then flows into the upper cover 2 and along the liquid guide channel 42 into the dye injection nozzle 43. The dye injection nozzle 43 sprays the dye onto the upper end of the inner cylinder 14, improving the flowability of the dye at the upper end of the inner cylinder 14, so that the fibers in the inner cylinder 14 are dyed uniformly. When the motor 27 is stopped and reversed at a certain time, the sleeve 32 moves upward and again pushes the wedge-shaped plate 46 into the interior of the upper cover 2, the liquid pushing plate 44 moves downward quickly, pushing the dye to flow into the liquid guide channel 42, increasing the pressure of the dye injection nozzle 43 for pulse injection, slowing down the flow rate of the dye in the dye vat 1, and reducing the damage to the fibers when the inner cylinder 14 drives the fibers to reverse.
