Problems solved by technology

Although these devices can improve the production efficiency and the dyeing effect of the dyed object through various measures from the structure, but because the supercritical fluid dyeing operation is a high-pressure operation, high-pressure equipment must be used, and these devices have high requirements for the tightness of the dyer. , it also requires a good quick-opening or reversing structure, which increases the complexity of the device structure and investment cost, and cannot realize large-scale continuous dyeing of the dyed object, which seriously restricts the popularization and application of this new technology

Abstract

The invention relates to the field of textile dyeing equipment, in particular to a jet device for supercritical fluid jet dyeing of yarns. According to the jet dyeing process, after installed in a supercritical fluid jet dying device, the jet device is connected with a supercritical fluid generation subsystem, a dye dissolution subsystem and a used fluid recovery and separation subsystem. According to the technical scheme, the jet device with or with no heating pipes comprises orifices, an orifice distribution pipe, high-pressure guide nozzles, a fluid distribution pipe, a fluid distribution pipe plug, low-pressure guide nozzles, a fluid inlet connecting pipe, a fluid outlet connecting pipe, a steam inlet connecting pipe and a steam outlet connecting pipe. By the use of the jet device, the problem that a high-pressure dyeing container is a necessity to the existing supercritical fluid jet dyeing device is solved; the jet device is simple in structure, safe and convenient to operate, good in dyeing uniformity and continuity, harmless to yarns under dyeing, and low in investment cost.

Description

1. Technical field [0001] The invention relates to the field of textile dyeing equipment, in particular to an injector for yarn dyeing by supercritical fluid spraying. 2. Technical Background [0002] The processing technology of traditional dyeing equipment has problems such as high water consumption, high energy consumption, long process, difficult sewage treatment and high cost. Supercritical fluid dyeing, especially supercritical carbon dioxide dyeing, uses supercritical fluid instead of water as the carrier of the dye to achieve water-free dyeing, thus fundamentally solving the problem of water pollution in the dyeing industry. At the same time, supercritical fluid dyeing technology has the advantages of supercritical fluid recycling, no pollution discharge, no drying of dyed objects, less fiber damage, simple and quick operation, high dyeing efficiency and low energy consumption, and has a good development and application prospect. [0003] At present, most of the sup...
