Abstract
A transplanar liquid transport tester for fabrics, comprising a liquid reservoir; a liquid-permeable support member having a first surface for supporting a fabric test sample, and a second surface for interfacing with liquid in the liquid reservoir; and means for maintaining a constant hydrostatic pressure in the liquid reservoir at the second surface of the support member for replenishing liquid through the support member to the first surface during testing.
Claims26
A method of characterising liquid or moisture transmission properties of a fabric, the method comprising the steps of:
- filling a container with a test liquid,
- delivering said test liquid from said container towards said fabric for transmission of said test liquid from a testing apparatus externally of the apparatus through said fabric,
- supplying said test liquid from a source reservoir to said container to replenish liquid lost from said container due to transmission of moisture through said fabric, and
- measuring the amount of liquid loss from said source reservoir to determine the moisture transmission characteristics of said fabric,
- wherein the share of the container is reconfigurable to simulate a plurality of postures of a human being.
A fabric characterization apparatus for characterising the respiratory or moisture transmission properties of a fabric, the apparatus comprising:
- a container for receiving a test liquid and for supplying said test liquid to a fabric of which the moisture transmission properties are to be characterised,
- a source reservoir for supplying said test liquid to said container for replenishing said container with said test liquid to compensate for loss of said test liquid from said container, and
- a monitoring device for recording and monitoring the supply of the replenishing liquid from said source reservoir to said container,
- wherein the share of the container is reconfigurable to simulate a plurality of postures of a human being.
