Color Fastness Perspiration Tester For Textiles Or Leather UNI EN ISO 105- E04
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). ( need equip with dry oven)
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.
