Abstract

A test body (10) for testing apparel items is described. The body has air entry means (20) for supplying conditioned gas into the inner of the test body, air exit means (30) for allowing the exit of said conditioned gas from the inner of the test body, and at least one perforation (60) through a side wall (50) of the test body (10) for allowing the conditioned air within the test body (10) to come into contact with an inner side of the apparel item. The pressure difference of said conditioned gas measured between the inner side of the apparel item and the air exit means is (30) less than 10%, preferably less than 5%, and more preferably substantially zero, when said conditioned gas has 0% humidity.

Claims

1. Test body having an inner and an outer side for testing apparel items having an inner side and an outer side, the test body comprising

an air entry for supplying conditioned gas into the inner of the test body,

an air exit for allowing the exit of said conditioned gas from the inner of the test body,

at least one perforation through a side wall of the test body for allowing said conditioned gas within the test body to come into contact with an inner side of the apparel item;

and

wherein pressure difference of said conditioned gas supplied into the inner of the test body during operation of said test body measured between the inner side of the apparel item and the air exit is less than 10% when said conditioned gas has 0% humidity and the humidity of the air on the outer side of said test body is 0%.

2. Test body according to claim 1 wherein the test body has a plurality of perforations in the side walls.

3. Test body according to claim 2 wherein the plurality of perforations are of a size and distribution to simulate sweat glands of a human body.

4. Test body according to claim 1 wherein the air entry means further comprises a distribution tube within the test body for evenly distributing the condition gas throughout the interior of the test body.

5. Test body according to claim 4 wherein the distribution tube is provided with at least one heating element for warming the distribution tube.

6. Test body according to claim 1 wherein the air exit means further comprises at least one extension tube in the inner of the test body.

7. Test body according claim 1 wherein the test body further comprises a ventilator situated in the inner of the test body for distributing the conditioned gas within the inner of the test body.

8. Test body according to claim 1 further comprising:

first temperature sensors in the test body for measuring the temperature of the conditioned gas within the test body.

9. Test body according to claim 1 further comprising:

first humidity sensors in the test body for measuring the humidity of the conditioned gas within the test body.

10. Test body according to claim 8 further comprising:

second temperature sensors on the outside of the side wall of the test body for measuring the temperature of the conditioned gas outside the test body.

11. Test body according to claim 9 further comprising

second humidity sensors on the outside of the side wall of the test body for measuring the humidity of the conditioned gas outside the test body.

12. Process for testing apparel items which comprises:

a) providing a test body defined in claim 1;

b) providing an item of apparel around the test body;

c) supplying conditioned air through the air entry and distribution tube;

d) collecting the conditioned gas as it passes out of the test body through the air exit;

e) measuring the humidity of the exited air;

wherein the pressure difference of the conditioned gas measured between the inner side of the apparel item and the air exit means is less than 10%.
