Waterless printing and dyeing device and method for fabric

Abstract

The invention discloses a waterless printing and dyeing device and method for fabric, and belongs to the technical field of fabric treatment. The waterless printing and dyeing device for the fabric comprises a device body, wherein a dyeing cavity is formed in the hollow device body, a cloth guide pipe is arranged on the left end wall of the dyeing cavity and communicated with the outside, a motoris fixed on the lower end wall of the dyeing cavity, a first dyeing mechanism is fixed on the upper end surface of the motor, and a second dyeing mechanism is arranged in a corresponding position on the upper side of the first dyeing mechanism. The invention also discloses a waterless printing and dyeing method adopting the waterless printing and dyeing device. Waterless printing and dyeing of thefabric are performed with supercritical CO2 fluid. The fabric printing and dyeing is performed by supercritical CO2 fluid, the process is high in printing and dyeing efficiency and good in printing and dyeing effect, participation of a water medium and other chemicals is not needed, pollution is avoided, and the printing and dyeing device has reasonable structure, can effectively ensure printingand 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.
