Investigating Liquid CO2 to Clean Textiles and Basketry
AbstractThis presentation illustrates the use of micron-sized snow particles to transfer and displace particles of surface soiling on delicate textile and basketry surfaces. Liquid CO2 from a tank (with syphon) connected to a valve and a nozzle expands without exchanging heat, thus becoming a mixture of gaseous CO2 and dry ice that surrounds the soil particles with a gas envelope which slides over the object surface, and then the CO2 volatilizes into the air. This momentum transfer and displacement system is dry, non-conductive, nonabrasive, and non-toxic. Our process of testing this technique is described.
