Description

Retractable 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 retractable supercritical fluid counter-jet dyeing device and a counter-jet dyeing process.

Second, background Art

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 and no pollution are realized, the influence of the textile industry on the environment can be fundamentally solved, and the supercritical fluid dyeing technology has the advantages of low energy consumption, high efficiency, simplicity in operation, no need of drying fabrics, small fiber damage and the like, and has good industrial prospect. However, the existing supercritical fluid dyeing device must have one or more high-temperature and high-pressure dyeing kettles, so that the device manufacturing cost is high, the dyeing process cannot be continuous, the fabric coloring is difficult to be uniform, the batch loading and unloading of the fabric are limited, and the device becomes a bottleneck factor restricting the industrial popularization and application of the supercritical fluid dyeing technology.

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 intellectual Property of China issued an invention patent with an announcement number of CN103866515B and a name of 'an injector for supercritical fluid spray-dyeing' on 9/30/2015, which adopts a porous structure cloth dyeing device, the cloth to be dyed is wound on a hollow roller with a porous structure, and the cloth to be dyed 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. Then, the patent office of the national intellectual Property office of China also authorizes an invention patent with an announcement number of CN103981661B in 2016 (01/20/2016), which is named as a novel sprayer for spray-dyeing of supercritical fluid, and adopts a squirrel-cage structure cloth dyeing device, the dyed cloth is wound on a hollow roller with 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 squirrel-cage cloth dyeing machine solves the problem that the support of the fabric and the roller do not move relatively. However, the three patents adopt single-side spray dyeing of the fabric, which not only causes color difference in dyeing of two sides of the fabric, but also causes the fabric to be damaged due to excessive deformation under the action of high-speed jet flow, thereby affecting the final dyeing effect. The patent office of the national intellectual Property office reissues an invention patent with the publication number of CN105200686B named as 'supercritical fluid counter-jet dyeing equipment' in 2017, 06 and 23, 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 this patent adopts the atmoseal device step by step of dull and stereotyped structure, has realized the continuity dyeing, but seal structure's sealed effect is still relatively poor.
