Abstract
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.
Claims45
A method for activating durable water repellency, the method comprising:
- depositing within a pressure vessel an article having one or more fibers wherein the one or more fibers of the article are bound with a durable water repellant;
- processing the article with a densified fluid to remove contaminants;
- and
- energizing the durable water repellant bound to the one or more fibers of the article.
A method for durable water repellant application, the method comprising:
- depositing within a pressure vessel an article having one or more fibers;
- processing the article with a densified fluid to remove contaminants wherein the densified fluid includes a durable water repellant;
- and
- energizing the durable water repellant bound to the one or more fibers of the article.
A durable water repellant activation system, the system comprising:
- a pressure vessel operable to hold a densified fluid at hyper-atmospheric pressure;
- a storage tank fluidly coupled to the pressure vessel for storing the densified fluid;
- a distillation system fluidly coupled to the pressure vessel and the storage tank wherein the distillation system is operable to remove suspended and dissolved contaminants from the densified fluid;
- and
- an article having one or more fibers wherein the one or more fibers of the article are bound with a durable water repellant and wherein interaction between the article and the densified fluid within the pressure vessel energizes the durable water repellant.
A durable water repellant application system, the system comprising:
- a pressure vessel operable to hold a densified fluid at hyper-atmospheric pressure wherein the densified fluid includes a durable water repellant in solution;
- a storage tank fluidly coupled to the pressure vessel for storing the densified fluid;
- a distillation system fluidly coupled to the pressure vessel and the storage tank wherein the distillation system is operable to remove suspended and dissolved contaminants from the densified fluid;
- and
- an article having one or more fibers wherein the one or more fibers of the article bind with the durable water repellant and wherein interaction between the article and the densified fluid within the pressure vessel energizes the durable water repellant bound to the one or more fibers.
