Description

Rotary supercritical fluid counter-jet dyeing device and counter-jet dyeing process

One, the technical field

The invention relates to the field of textile dyeing equipment, in particular to a rotary supercritical fluid counter-jet dyeing device and a counter-jet dyeing process.

Second, background Art

With the rapid development of social economy, the requirements of people on the environment are higher and higher. In recent years, the annual discharge amount of the textile industry wastewater of China still accounts for about 10 percent of the total amount of the industrial wastewater of the year. The influence of the textile industry wastewater on the environment seriously restricts the development of the printing and dyeing process, the supercritical fluid dyeing technology uses fluid in a supercritical state to replace water as a dye carrier, redundant dye and supercritical fluid can be recycled, zero emission is realized, no pollution is caused, and the influence of the textile industry on the environment can be fundamentally solved. The supercritical fluid dyeing technology has the advantages of low energy consumption, high efficiency, simple operation, no need of drying fabrics, small fiber damage and the like, and has good industrial prospect.

The existing supercritical fluid dyeing device needs one or more high-temperature and high-pressure dyeing kettles, the manufacturing cost of the equipment is high, and although the application of the technologies such as laminate binding and the like can greatly reduce the manufacturing cost of the device, the supercritical fluid dyeing device still is one of the main limiting factors for popularization and application of the supercritical fluid dyeing technology. At present, various supercritical fluid dyeing devices reported at home and abroad are intermittent dyeing devices, an insurmountable gap exists between batch loading and unloading of fabrics and continuous production, and the intermittent dyeing device is another main limiting factor for hindering industrialization of a supercritical fluid dyeing technology. In the intermittent dyeing equipment, the fabric is in a static state, and even if a method of alternately changing the flow direction of the supercritical fluid and the like is adopted, the uniformity of fabric dyeing is difficult to ensure.

The patent office of the national intellectual Property office authorizes an invention patent with an announcement number of CN101798735B and a name of a supercritical fluid spray dyeing device at 23.11.2011, the device absorbs the advantages of a supercritical fluid spray coating technology and a traditional spray dyeing technology, overcomes the defect that a high-pressure dyeing device is required to be used in the conventional supercritical fluid dyeing device, but the device directly sprays supercritical fluid on fabrics without any shielding, has the defects of high jet pressure drop, small covering radius, non-compact structure and the like, and the fabrics are extremely easy to damage by high-pressure jet. Then, the patent office of the national intellectual property office authorizes an invention patent with an announcement number of CN103866515B, a name of sprayer for supercritical fluid spray-dyeing and an announcement number of CN103981661B and a name of novel sprayer for supercritical fluid spray-dyeing sequentially from 2015 9, 30 and 2016 01, 20, and respectively adopts a porous structure and a squirrel cage structure cloth dyeing device, the dyed cloth is wound on a hollow roller with a porous structure or a squirrel cage structure and continuously moves along with the rotation of the roller, and the supercritical fluid is sprayed to the hollow roller to complete dyeing. The porous structure cloth dyeing machine solves the supporting problem of the fabric in the supercritical fluid spray dyeing process, but the fabric and the roller do not move relatively, so that the fabric wound on the non-porous area of the roller is easy to dye poorly; the squirrel-cage cloth dyeing machine solves the problem that the support of the fabric and the roller do not move relatively. The single-side spray dyeing of the fabric is adopted in the above patents, so that the dyeing of two sides of the fabric has chromatic aberration, and the fabric is damaged due to excessive deformation under the action of high-speed jet flow, so that the final dyeing effect is influenced. The patent office of the national intellectual Property office in 2017, 06 and 23, authorizes an invention patent with the publication number CN105200686B and named as 'supercritical fluid counter-jet dyeing equipment', and sprays supercritical fluid dyeing liquid on two sides of the fabric simultaneously, so that tension generated in the fabric under the action of high-pressure jet flow is eliminated, and the two sides of the fabric are uniformly colored. Although continuous dyeing is realized by adopting the gradual air sealing device with the flat plate structure, the sealing effect of the sealing structure is still poor.
