Problems solved by technology

However, the use of supercritical carbon dioxide dyeing technology to dye warp beams still has problems such as large batches, low penetration rate of dye solution, uneven dyeing, etc., and it is still impossible to achieve high-quality dyeing production
In addition, supercritical carbon dioxide anhydrous dyeing process mostly adopts hot oil bath heating method, which consumes a lot of energy and has a strong smell. It is the main energy-consuming component in supercritical fluid dyeing equipment.
These outstanding problems have greatly limited the application of supercritical carbon dioxide dyeing in beam dyeing

Embodiment 1

[0037] The present invention combines the attached figure 1 , 2 , 3 for explanation.

[0038] A supercritical carbon dioxide warp beam dyeing rack, comprising a central support tube 17 and a rotating disk 19, the central support tube 17 is a hollow porous structure; the hole diameter is 5mm. Such as image 3 As shown, the rotating disc 19 is a hollow cylinder with four holes on the upper part of the hollow cylinder, and a short shaft 24 is connected to the lower part of the hollow cylinder, such as figure 1 As shown, the warp beam dyeing rack takes the central support tube 17 as the center, and sequentially includes the central support tube 17, the three-arm shaft 18, the warp shaft support shaft 16, the warp shaft 15, and the porous outer cover 14 from the inside to the outside; the three-arm shaft is three Hollow tube, the hollow tube is a porous structure; the hole diameter is 1mm.

[0039] Such as figure 2 As shown, the bottom of the central support tube 17 and the ...

Embodiment 2

[0046] Such as figure 1 As shown, a supercritical carbon dioxide beam dyeing kettle includes a movable sealing cover 9 and a cylinder body 10, the movable sealing cover 9 is fixed by a positioning pin 8, and is connected with the end face 6 of the dyeing kettle body through a quick-opening clamp 7; the cylinder body 10 is provided with a heating jacket 3; the upper end of one side of the heating jacket 3 is provided with a heating medium outlet 21, and the lower end of the other side is provided with a heating medium inlet 4; the upper part of the cylinder body 10 is provided with a carbon dioxide fluid outlet 5; Be fixedly provided with the warp beam dyeing rack in embodiment 1, cylinder body bottom is provided with hole, and hollow rotating shaft (23) top passes this hole, is threadedly connected with the minor axis (24) in the warp beam dyeing rack. The hollow rotating shaft is connected with the motor outside the cylinder body, and the bottom of the rotating shaft is conn...

Embodiment 3

[0051] 5kg reactive disperse red dye is put into the dye still, and 120kg wool is put into the dyeing still of embodiment 2 through beam. Turn on the refrigeration system, when the pressure of the storage tank drops to 4.2-4.6MPa, the liquid level of the storage tank rises to 422-424mm, and start to introduce carbon dioxide gas. Then, turn on the heater and steam pump to heat the temperature to 96-98°C, start the high-pressure pump to pressurize to 23-24MPa; ~45min. After dyeing, turn off the high-pressure pump, motor, heater and steam pump, release the pressure, lower the temperature and keep it at 3.5-4MPa, 35-38°C to recover carbon dioxide and dye, and take out the dyed wool warp beam. After dyeing, the color fastness to washing of the yarn reaches grade 3-4, the color fastness to rubbing is grade 4, and the color fastness to light and weather can reach grade 4.

Abstract

The invention discloses a supercritical carbon dioxide beam dyeing frame, dyeing kettle and dyeing method. The dyeing frame comprises a central supporting pipe (17) and a rotating disc (19), the rotating disc (19) is of a hollow cylinder structure, four holes are formed in the upper portion of the rotating disc, a short shaft (24) is arranged on the lower portion of the rotating disc in a communicated mode, and the beam dyeing frame comprises the central supporting pipe (17), a three-arm shaft (18), a beam supporting shaft (16), a beam (15) and a porous cover in sequence from inside to outside with the central supporting pipe (17) as the center; the bottom of the hollow rotating shaft is connected with a carbon dioxide fluid pipe through a rotary sealing device. According to the beam dyeing frame, dyeing kettle and dyeing method, the central supporting pipe and the three-arm shaft rotate in the circumferential direction, large impact force is generated by the carbon dioxide fluid by means of the centrifugal force, dye passes through yarn rapidly, and the dye permeability is improved. According to the steam heating type supercritical carbon dioxide beam dyeing kettle, high-temperature steam inside a textile mill is utilized, a steam heating mode is adopted, and the heat utilization rate is high.

Description

technical field [0001] The invention relates to a supercritical carbon dioxide beam dyeing frame, a dyeing kettle and a dyeing method. Background technique [0002] Traditional textile dyeing mainly uses water as the medium, uses a large amount of chemical substances such as dyes and auxiliaries, and consumes a large amount of water. It is a dyeing technology with high energy consumption, high pollution, and high emissions. It not only causes serious pollution to the environment, but also restricts sustainable development of the textile printing and dyeing industry. With the rapid development of modern science and technology, supercritical fluid technology has been increasingly valued by countries all over the world, and has been gradually applied to many industries such as chemical industry, biology, hygiene, food, printing and dyeing, and new materials. Supercritical carbon dioxide anhydrous dyeing technology is considered as a "green and sustainable development technolog...
