Description :

Perspirometer AND INCUBATOR

The Perspirometer applies a specified pressure to a package of test specimens separated by acrylic or glass plates. The spring loaded mechanism ensures the correct pressure is maintained when the loading Weight is removed. Two loading Weights are available to accommodate the requirements of the ISO and AATCC test methods.

Manufactured from high grade stainless steel, the Perspirometer is rigid and corrosion resistant.

The Incubator provides, and accurately maintains, the controlled environmental conditions for the duration of the test specified by the standards.

ISO Certificates of Calibration are available which provide validation of instrument performance and specification.

Colour Fastness to Perspiration, Water and Sea Water

To test colour fastness to perspiration, specimens (fabric, yarn or fibre) in contact with Multifibre Adjacent Fabric, are treated in two different solutions containing histidine, one alkaline and one acidic.

The specimens are subsequently drained and placed under constant pressure between separator plates in the Perspirometer. Up to 20 test specimens can be accommodated.

The units are then placed in an Incubator for 4 hours at 37˚C (body heat).

After drying, change in colour of the specimens and staining of the adjacent fabrics are assessed with Grey Scales.

Separate Perspirometer units must be used for alkaline and acidic tests to avoid chemical interaction.
