Supercritical Carbon Dioxide as an Impregnation Medium for Producing Functional Materials in Textile Finishing

Supercritical carbon dioxide (scCO2) is an environmentally friendly technology and has properties such as high diffusivity, low surface tension, and simple solvent removal at the end of the process. It is used to overcome environmental pollution resulting from textile industries such as dyeing and finishing and adds a functional property to the material by using dyes that have functional properties or metal oxides from which we obtain treated fabrics such as antimicrobial, water and oil resistance, UV protection and flame-resistant fabrics. This paper discusses current research on the use of scCO2 as an impregnation medium in the production of various functional materials in order to stimulate further research on the use of scCO2 in textile finishing.
