Abstract: This paper introduces a method of using supercritical carbon dioxide fluid for the waterproof and anti-mosquito finishing of fabrics. Through a self-designed high-pressure device, the supercritical carbon dioxide fluid can effectively bring the functional finishing agent to the fiber surface, and form film under a certain temperature condition, empowering the fabric good waterproof and anti-mosquito function.The overall process setting is environmentally friendly, simple and effective, providing a reference for the application of supercritical carbon dioxide fluid in the field of textile functional finishing.

Key words: supercritical carbon dioxide; water repellent; anti-mosquito; functional treatment
