Problems solved by technology

[0003] Wool fabric is loved by people because of its good warmth retention, soft wool, good elasticity, and strong heat insulation performance. Among them, during the production and processing of wool fabric, people will print and dye wool fabric. The traditional dyeing technology still places a single piece of wool fabric in the dyeing vat for dyeing, but this dyeing technology is not only slow and inefficient, which affects the dyeing effect, but also the uniformity of dyeing is not very good, and the remaining Dye waste liquid will be discharged randomly, which not only pollutes the environment, but also wastes water resources

Embodiment 1

[0038] The invention discloses a wool fabric high-pressure water-saving jet dyeing technology and vaporized water recovery system. The specific steps are as follows:

[0039] Step 1, adding dye and water into the dye vat for mixing;

[0040] Step 2: Heating the dyeing solution to 40°C at a rate of 2°C / min, while adjusting the pressure in the high-pressure cavity of the dyeing shell to 22MPa, and adjusting the temperature in the high-pressure cavity to 40°C;

[0041] Step 3: Transport the wool fabric into the high-pressure chamber, use a centrifugal pump to suck the dye in the dye tank, and then the centrifugal pump transports the dye to the nozzle in the high-pressure chamber, and the nozzle will uniformly jet-dye the wool fabric;

[0042] Step 4. Transport the jet-dyed wool fabric to the low-pressure chamber of the dyeing shell. The pressure in the low-pressure chamber is 0.13MPa and the temperature is 20°C. The water attached to the surface of the wool fabric is vaporized, a...

The technology provided by the invention has the advantages of high dyeing uniformity, water resource saving and high production efficiency, etc.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a wool fabric high-pressure water-saving jet dyeing technology and a vaporized water recovery system. Background technique [0002] Printing and dyeing, also known as dyeing and finishing, is a processing method and a general term for pretreatment, dyeing, printing, finishing, washing, etc. The undergraduate dyeing and finishing major has now been merged into the light chemical engineering major. In the Neolithic Age years ago, our ancestors were able to dye linen red with hematite powder. The primitive tribes living in the Nomuhong area of ​​the Qaidam Basin in Qinghai could dye wool yellow, red, brown, and blue. In the Shang and Zhou dynasties, the dyeing technology continued to improve, and full-time officials "dyeers" were set up in the palace handicraft workshops to "hand-dye grass" to manage the dyeing production, and the dyed colors were also excellent. Increasing. By t...
