Answer: The research and development of polymer dyeing auxiliaries in printing and dyeing has achieved clean printing and dyeing without pollution and zero emissions. As early as before the launch of the “263” special action, with the continuous improvement of environmental protection requirements and sustained high pressure, most printing and dyeing enterprises have realized the environmental bottlenecks they are facing and begun to actively seek ways out.

Answer: The advantages of waterless dyeing technology mainly lie in environmental protection and efficiency. Firstly, this technology does not require the use of water, thus significantly reducing the consumption of water resources and minimizing environmental pollution. Secondly, since there is no need for cleaning and drying after dyeing, it can save a lot of time and energy.

Answer: Currently, waterless dyeing technology has been applied in some textile enterprises. The newly developed waterless dyeing technology has introduced printing and dyeing technology, which once and for all solves the problem of printing and dyeing wastewater discharge. Green and recyclable organic solvents are used to replace water as active dyeing, fully replacing traditional water bath dyeing methods.

Answer: Save resources, reduce pollution, improve efficiency, promote green transformation, etc

Answer: Heat and pressurize CO2 to a supercritical fluid state that is neither gas nor liquid, and continuously circulate it between the fuel tank and the dyeing tank through a circulation pump. The supercritical CO2 fluid dissolves the fuel and dyes the fabric.

Answer: This technology uses critical CO2 as the dyeing medium to dissolve the fuel and deliver it to the fiber voids, allowing the fuel to quickly and evenly dye onto the fabric. After dyeing, CO2 can be fully separated from the fuel without the need for cleaning, drying, or other operations. Unused fuel can be recycled.
