A kind of fabric non-water printing and dyeing equipment and method thereof

Abstract

A waterless printing and dyeing equipment for fabrics and its method belong to the technical field of fabric treatment. The invention discloses a waterless printing and dyeing equipment for fabrics. A cloth guide pipe is provided for communicating with the outside world, and a motor is fixedly installed on the lower end wall of the dyeing chamber, and a first dyeing mechanism is fixedly installed on the upper end surface of the motor, and a second dyeing mechanism is installed at a corresponding position on the upper side of the first dyeing mechanism. At the same time, the present invention Also disclosed is a waterless printing and dyeing method using the waterless printing and dyeing equipment, using supercritical CO 2 Fluid carries out the waterless printing and dyeing of fabric, and the present invention utilizes supercritical CO 2 Fluid is used for fabric printing and dyeing, the process has high printing and dyeing efficiency, good printing and dyeing effect, does not require the participation of water medium and other chemicals, and has no pollution. The printing and dyeing equipment disclosed by the invention has a reasonable structure, can effectively ensure the printing and dyeing quality, and is easy to maintain and replace.

Description

technical field [0001] The invention belongs to the technical field of fabric treatment, and in particular relates to a waterless printing and dyeing equipment for fabrics and a method thereof. Background technique [0002] Today's society at home and abroad is paying more and more attention to global environmental issues, requiring manufacturers and processors to realize clean production in all aspects of product manufacturing and be responsible for the ecological environment. As an important link in the textile industry, dyeing and finishing processing currently has many problems. For example, the consumption of water resources is huge, and the types and quantities of chemicals used in the processing process are large. As a result, the discharged printing and dyeing wastewater usually contains a variety of high-concentration pollutants and seriously pollutes the environment. This situation is consistent with today's society's commitment to environmental protection. contra...

Problems solved by technology

For example, the consumption of water resources is huge, and the types and quantities of chemicals used in the processing process are large. As a result, the discharged printing and dyeing wastewater usually contains a variety of high-concentration pollutants and seriously pollutes the environment. This situation is consistent with today's society's commitment to environmental protection. contrary to the purpose of

[0003] At present, some printing and dyeing equipment use vacuum negative pressure adsorption to print and dye atomized dyes on fabrics, which reduces the discharge of printing and dyeing wastewater and the waste of dyes to a certain extent, but the dyes that can be selected for printing and dyeing through this technical solution must be Because it is easy to sublimate, the range of selection is small. At the same time, for fabrics of different materials, after level dyeing, the color fixing effect of the dyed goods is different, and the scope of application is small.
