Abstract
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.
Claims6
A method of dyeing a material, the method comprising:
- positioning a first sacrificial material with a first dye profile and a target material with a second dye profile in a common pressure vessel such that the first sacrificial material is in contact with the target material;
- introducing carbon dioxide (“CO2”) within the pressure vessel such that the CO2 achieves a supercritical fluid (“SCF”) state while in the pressure vessel;
- and
- perfusing, with SCF CO2, the target material with dye from the first sacrificial material dye profile.
