    摘要： A supercritical fluid dyeing and finishing system has a fabric warp beam dyeing kettle. A fabric warp beam dyeing and finishing unit is arranged in the fabric warp beam dyeing kettle. An external magnetic transmission device II is arranged outside the fabric warp beam dyeing kettle. The fabric warp beam dyeing and finishing unit includes a porous pipe I and a porous pipe II. The porous pipe I and the porous pipe II are connected with an inlet of the fabric warp beam dyeing and finishing unit through a bearing I and a bearing II. A fluid ejector is connected with the inlet of the fabric warp beam dyeing and finishing unit and disposed in the vicinity of the porous pipe I and the porous pipe II.

    摘要： A method and kit for producing reversibly dyed soft contact lenses. The contact lenses are submerged in saline solution and a dye is added to the saline solution, either directly or by means of a strip that has been impregnated with the dye. Preferred dyes include the common dyes sodium fluorescein, lissamine green, and rose bengal. After a period of time, the lens absorbs the dye and can be removed from the solution and placed on the eye. Once the lens is illuminated with ultraviolet light, it will glow or fluoresce. This creates a dramatic effect, particularly in dimly lit areas. The dyeing method does not utilize heat and thus is reversible. Soaking the lens in additional saline solution for a period of time will cause the dye to return to its non-dyed state.

    摘要： Various types of fibers, especially fibers which can ordinarily only be dyed with some difficulty, are dyed in a relatively short period of time at a relatively low temperature by using a dye bath in which the dye is dissolved in concentrated sulfuric acid, and in which a buffering compound, such as an alkali salt of a weak acid, is preferably added.

    摘要： The invention relates to a separation, recycling and self-cleaning system of a supercritical fluid dyeing machine. The system includes a supercritical fluid medium reservoir, one or more parallel dyeing units, a high-pressure pump, a primary separator, a secondary separator and a membrane separator sequentially connected. A dyeing medium and residual dye in dyeing units can be efficiently separated and recycled simultaneously, and when the separation and recycling is finished, each dyeing unit can be directly opened so that the dyeing units and products can be cleaned after dyeing, thereby improving the production and processing efficiency of supercritical fluid waterless dyeing and achieving simple operations, complete separation, stability and reliability and a blowback self-cleaning. The invention has a broad application prospect and practical significance in fundamentally addressing generation and emission of pollutants in the textile printing and dyeing industry and realizing energy conservation, consumption reduction, emission reduction and clean production.
