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.

Supercritical fluid (SCF) is used to scour a target material to leave scour elements, such as oligomers and oils from the target material. Carbon dioxide (CO.sub.2) is introduced into a pressure vessel also containing the target material to be scoured. The CO.sub.2 is raised in temperature and pressure to a SCF state. The CO.sub.2 is recirculated within the pressure vessel to scour the target material. An exchange of the CO.sub.2 is occurs allowing for the scoured elements to be removed from the CO.sub.2 and therefore from within the pressure vessel. Operation variables such as temperature, pressure, time, internal flow rate, and CO.sub.2 exchange are adjusted to achieve a scouring of the target material.

Methods are directed to the use of a supercritical fluid for finishing a target material with a finishing material. One or more variables selected from temperature, pressure, flow rate, and time are manipulated to increase efficiencies in the finishing process. As temperature or pressure are decreased causing a change in the density of a supercritical fluid carbon dioxide, which in turn causes a precipitation of dissolved material finish with the carbon dioxide, other variables are maintained above threshold values to increase the uptake of the material finish by the target material. This improvement reduces time by limiting cleaning processes of the system, saves materials used in the cleaning process, and saves energy used to achieve cycles of the process, in aspects.

Methods are directed to the use of a supercritical fluid for performing a dyeing of a material such that dye from a first material is used to dye a second material. A supercritical fluid is passed through a first material in a pressurized vessel. The supercritical fluid transports the dye from the first material to at least a second material causing a dye profile of the second material to change as a result of dye from the first material perfusing the second material.
