Abstract
The invention relates to the field of textile dyeing, in particular to a continuous jig dyeing device for supercritical fluid and a dyeing technology. The double-integrated jig dyeing device or three-integrated jig dyeing device continuous jig dyeing device for supercritical fluid is composed of two or three integrated jig dyeing devices, filters, a booster, a supply tank, a buffering tank, switching valves, a supply valve, blow-off valves, an emptying valve, safety valves, a pressure display gauge, pressure control gauges, temperature control gauges, pipes and pipe fittings. The technology includes the steps that 1, system is initialized; the integrated jig dyeing devices are initialized; 3, feeding of supercritical fluid media, supercriticality and jig dyeing are carried out on the integrated jig dyeing devices; 4, feeding of supercritical fluid media, supercriticality and rinsing are carried out on the integrated jig dyeing devices again; 5, pollutants are discharged from the integrated jig dyeing devices. According to the device and the dyeing technology thereof, the process is simple and convenient to implement, preparation time before dyeing is short, equipment investment is small, production efficiency is high, operation cost is low, and emissions of the supercritical fluid media are low.
Description
[0001] 1. Technical field [0002] The invention relates to the field of textile dyeing, in particular to a supercritical fluid continuous dyeing device and a dyeing process. [0003] 2. Technical background [0004] The traditional water dyeing process will bring a large amount of industrial wastewater, and the water pollution problem seriously restricts the development of the traditional dyeing industry. At present, the proportion of water reuse in the traditional water dyeing production process is very low, and the cost of sewage treatment is high. [0005] Supercritical fluid dyeing uses supercritical fluid, especially supercritical carbon dioxide, to replace water as the carrier of dyes for dyeing, realizing anhydrous dyeing, thereby fundamentally solving the problem of water pollution in the dyeing industry, and has a good development and application prospect. [0006] Summarizing the characteristics of the existing supercritical fluid dyeing process, it can be seen that...
