Color Fastness Perspiration Tester

Color Fastness Perspiration tester

Application:

Dyed & printed textile fabric & garments stain other materials when comes in contact with water and the human perspiration either acidic or alkaline. This important property of textiles is evaluated keeping the sample with adjacent fabrics wetted in perspiration solution under standard pressure. 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.

Usage:

To determine color fastness to water and perspiration in textiles. It’s also employed to predict the potential of white or pastelcoloured textiles to yellow in transit or storage.

Test procedure

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.
