Abstract
A method and an apparatus for drying a piece of textile which is impinged upon by an air flow having a varied partial steam pressure to evacuate moisture. The method and apparatus are particularly suitable for drying a piece of textile with a layered structure having a semi-permeable membrane.
Claims19
A method for drying a piece of textile, wherein the piece of textile has a layered structure encompassing a semi-permeable membrane that allows water vapor to pass through but keeps out water in liquid form, the method comprising:
- generating an air flow having an oscillating partial water vapor pressure;
- and
- driving the water vapor out of the piece of textile through the semi-permeable membrane by impinging the piece of textile with the air flow,
- wherein the driving the water vapor out includes:
- evacuating moisture and generating a partial pressure gradient over the semi-permeable membrane,
- wherein the evacuating and the generating deliberately varies and disrupts a dynamic equilibrium in the semi-permeable membrane.
A method for drying a piece of textile, which includes a layered structure encompassing a semi-permeable membrane that allows water vapor to pass through the textile and prevents water in liquid form from passing through the textile, in a drying apparatus, the apparatus comprising a container for accommodating the piece of textile, an air flow generator, and a controller controlling the air flow generator,
- the method comprising:
- deliberately varying and disrupting a dynamic equilibrium in the semi-permeable membrane in the container and driving the water vapor out of the piece of textile through the semi-permeable membrane,
- wherein the deliberately varying and disrupting the dynamic equilibrium in the semi-permeable membrane and driving the water vapor out of the piece of textile includes:
- generating an air flow in the container having the piece of textile using the air flow generator, the generated air flow having an oscillating partial water vapor pressure;
- and
- evacuating moisture and generating a partial pressure gradient over the semi-permeable membrane by impinging the piece of textile in the container with the air flow.
