Problems solved by technology

[0005] Summarizing the characteristics of the existing supercritical fluid dyeing devices, it can be seen that due to the characteristics of the supercritical fluid itself, the dyeing device for supercritical fluid dyeing must use high-pressure equipment, and the sealing performance of the dyeing device is also very high. Very good quick opening or reversing structure, which increases the complexity of the device structure and investment cost, and cannot achieve continuous dyeing in large quantities, 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 supercritical fluid continuous dip dyeing equipment which is formed by a cleaning unit, a dip dyeing unit, a rinsing unit, working fluid air seal units, air seal units, a connecting plate, a sealing box, a sealing part and a pressure adjusting valve. The first air seal unit, the first working fluid air seal unit, the cleaning unit, the second working fluid air seal unit, the dip dyeing unit, the second working fluid air seal unit, the rinsing unit, the fourth working fluid air seal unit and the air seal unit are sequentially installed according to the direction of the supercritical fluid continuous dip dyeing process. Supercritical fluid flows in from one side of a continuous steeper and flows out from the other side after penetrating through a dyed object, and in the process, the dyed object is continuously steeped, which is beneficial for improving dyeing quality; meanwhile, by the adoption of a step-by-step pressure reducing air seal structure, continuous dyeing is achieved really, and the equipment is simple and compact in structure and excellent in manufacturability.

Description

[0001] 1. Technical field [0002] The invention relates to the field of textile dyeing equipment, in particular to a supercritical fluid continuous dipping equipment. [0003] 2. Technical background [0004] The problem of water pollution seriously restricts the development of traditional dyeing industry. Supercritical fluid dyeing uses supercritical fluid instead of water as the carrier of dyes for dyeing, realizing anhydrous dyeing, thus fundamentally solving the problem of water pollution in the dyeing industry, and has a good development and application prospect. [0005] Summarizing the characteristics of the existing supercritical fluid dyeing devices, it can be seen that due to the characteristics of the supercritical fluid itself, the dyeing device for supercritical fluid dyeing must use high-pressure equipment, and the sealing performance of the dyeing device is also very high. Very good quick opening or reversing structure, which increases the complexity of the dev...
