    摘要： The invention discloses a waterless fiber dyeing method using supercritical carbon dioxide fluid as medium. Dry fibers are tightly loaded layer by layer in a porous yarn cage. After dyeing, the fibers are cleaned to remove unfixed dyes by an online way, thereby obtaining waterless dyed dry fiber products with good quality. With the supercritical carbon dioxide dyed by a dye, the invention can not only solve the problems of high energy consumption, high discharge, high pollution in the traditional dyeing process, but also obtain better dyeing effect. The invention has a simple process and convenient operation, which can effectively realize dry dyeing processing. The reaction is mild, avoiding the use of a large amount of water, heat and additives in high concentration, which has the features of being high efficiency and environmentally friendly.

    摘要： A method of photocatalytic white discharge printing for achieving patterns on textiles includes: substrates are closely integrated with patterned printing plates, or patterned printing plates are fixed in one side or both sides of the substrates; then put them in a reactor equipped with a light source and occupied by the photocatalytic white discharging formulation. The method has the characteristics of simple process, short processing, easy controlling and wide adaptability, along with eliminations of the need for printing pastes and expensive printing apparatuses, so as the complicated process in the conventional printing method. Additionally, photocatalytic solution can be reused, avoiding generous applications of chemical agents and waste discharges in the conventional printing method. It is also beneficial to cutting costs, along with significant advantages of energy saving, emission reduction and cleaner production.

    摘要： The invention relates to a multi-pipe quantitative medium filling system of a supercritical fluid waterless dyeing machine. The system comprises a supercritical fluid medium reservoir, a stop valve, and a medium filter sequentially connected by a high-pressure main pipe, and at least two filling branches independent of each other and connected to the medium filter. Each filling branch includes a booster pump, a supercritical fluid high-pressure mass flowmeter, a ball valve, and a dyeing unit sequentially connected along a medium forward direction by a high-pressure branch pipe. By using a mass-measurement filling system having multiple branches independent of each other, the invention can effectively realize simultaneous and accurate quantitative medium filling for separate dyeing units and differentiated filling for dyeing units with different medium masses, thus overcoming disadvantages such as unreliability, inaccuracy and low use efficiency of a conventional method, and also making a dyeing operation simple and scientifically feasible.

    摘要： The present invention relates to a waterless fiber dyeing method using a mixed fluid medium, in which supercritical carbon dioxide fluid medium is mixed with steam to form a mixed fluid medium, so that the waterless fiber dyeing effect to natural fibers is improved. The method of the invention can effectively modify the hydrophobic supercritical carbon dioxide fluid medium and improve the polarity thereof, thereby increasing the solubility of polar dye under the dyeing condition and simultaneously expanding the fiber. Thus, the present invention significantly improves the dyeability and dyeing behavior of the hydrophilic fibers in supercritical carbon dioxide fluids. The invention has the advantages of simple process, convenient operation and low energy consumption, and avoids consuming a large amount of water resources and discharging pollutants in the traditional process, and has the characteristics of environmentally friendly and high efficiency.
