Deposition of Finishes and Dyes in Materials Dried Using Microwave Heating*

Abstract

The use of microwave heating for drying can enhance the uniformity of deposition of dyes and finishes in textile and other fibrous materials. The migration of dyestuff in bundles of textile fabric was measured and compared for samples dried using different rates of microwave and conventional surface heating. The microwave heating resulted in a much improved uniform deposition of dyes and finishes when compared to conventional surface heating.
