Dyeing hand sample machine and dyeing method thereof

Abstract

The invention discloses a dyeing hand sample machine comprising a dyeing kettle, a front end pipeline, a rear end pipeline, a dye recovering tank, a cold water thermostatic bath, a carbon dioxide high-pressure pump and a pressure reducing device, wherein the front end pipeline and the rear end pipeline are respectively communicated with the dyeing kettle; a carbon dioxide input port, the cold water thermostatic bath and the carbon dioxide high-pressure pump are arranged on the front end pipeline; a hot oil thermostatic bath is arranged between the carbon dioxide high-pressure pump and the dyeing kettle; the pressure reducing device is arranged on the rear end pipeline; the dye recovering tank is positioned at the rear end of the pressure reducing device; a recycling pipe, through which the front end pipeline is communicated with the rear end pipeline, is arranged between the front end pipeline and the rear end pipeline; and a recycling bump or a compressor is arranged on the recycling pipe. The dyeing hand sample machine has the advantages of complete functions, simplicity in operation and very high sample making speed, thereby filling a gap in the production of the supercritical dyeing industry.

Description

technical field [0001] The invention belongs to the field of fabric dyeing, and in particular relates to a dyeing sample machine and a dyeing method thereof. Background technique [0002] Most of the traditional fabric dyeing adopts wet dyeing process. For a long time, a large amount of waste water produced by wet dyeing has seriously polluted the environment. Although all enterprises have adopted water resource environment, it has endangered people's life and health. [0003] In order to reduce environmental pollution and save production costs, in recent years, people have devoted themselves to the research of applying supercritical fluid to waterless printing and dyeing technology. The supercritical fluid dyeing process uses the better mass transfer performance of a certain fluid in the supercritical state and the solubility of non-polar substances to dye synthetic fibers. It is a novel and environmentally friendly waterless printing and dyeing process. The dyeing process...

Problems solved by technology

[0004] However, although the current supercritical carbon dioxide dyeing technology has gradually matured from the technical experience of equipment development, it still cannot be applied industrially. The main reason is that there is no corresponding proofing machine, so that the direct dyeing process conditions cannot be obtained. Therefore, in order to bring advanced supercritical carbon dioxide dyeing technology into large-scale production as soon as possible, it is urgent to provide a proofing device for dyeing with supercritical carbon dioxide.
