Application and Activation of Durable Water Repellant Using a Densified Fluid
A pressurized system using densified fluid can apply and/or activate durable water repellant. Durable water repellant bound to fibers of an article of clothing can be activated by first removing contaminants via a pressurized densified fluid cleaning process and thereafter imputing energy into the durable water repellant via the article's interaction with the densified fluid and its gaseous rinse cycle.
1 . A method for activating durable water repellency, the method comprising:
depositing within a pressure vessel an article having one or more fibers;
introducing into the pressure vessel a densified fluid wherein the densified fluid includes a durable water repellant;
creating a mechanical interaction, apart from the pressure vessel, between fibers of the article, the densified fluid and the durable water repellant; and
energizing, within the pressure vessel, the durable water repellant bound to the one or more fibers of the article.
