Application of Ultrasound and Microwaves during Treatment of Fabrics with Liquid-Repellent Finishes,

Abstract

Two types of military fabric were treated with a liquid-repellent fluorochemical finish in the presence of high-frequency sonic energy (ultrasound) over a range of frequencies and power levels. Fabric properties such as physical strength, liquid repellency, and durability of repellency to laundering and wearing were evaluated following treatment to determine the effects of using ultrasound during the finishing process. A second series of tests was carried out to determine whether microwave energy could be employed for the purpose of ensuring a more uniform impregnation of the fabrics, as well as to accelerate the drying and curing processes.
