Determination of Color Fastness to Perspiration:
Method Followed: ISO 105 E04, AATCC: 15
Required Equipment: Perspirometer, Woven Dryer, Multifibre, Below mentioned Chemicals, Distilled water and Grey scale.
Working Procedure:
Taking the sample fabric from bulk and then conditioning for 04.30 to 06 hours
↓
Select the sample for test and cut the specimen in 04cm*10 cm.
↓
Attach with multi-fibre fabric of same size.
↓
Make-up solution with below chemicals:
For Acid:
L-histadine monohydrochloride: 0.5 gm/litre
Sodium Chloride: 5 gm/litre
Sodium dihydrogen orthophosphate dihydride: 2.2 gm/litre
For Alkali:
L-histadine monohydrochloride: 0.5 gm/litre
Sodium Chloride: 5 gm/litre
Di Sodium hydrogen orthophosphate 2-hydrate: 2.5 gm/litre
Water: 1000 cc
↓
Immerge the sample and Multifibre fabric into solution for 01 hours
↓01 sample 50 ml, Solution 1:50
Place in between the perspirometer plate and fix with proper weight.
Put into the perspirometer with 100% pick up
↓
Set the perspirometer in woven dryer at 37oC temp for 4 hours
↓
Out the perspirometer in woven dryer & set it another dryer
↓
Dry the sample at 60oC temp for 60 min
↓
Measurement with grey scale for shade change and staining.

As we all know, the color fastness to perspiration and the light fastness are closely related to our daily lives. So we need a professional Perspirometer to measure the color fastness test to water.
Perspirometer
Fabric Scale, to nicely determine the weight of the fabric, paper, cardboard, and film, etc. Fabric Weight Scale complies with ISO3801, ASTM D3776/2646, BS 3424/2471, etc. For more information, please click on https://www.testextextile.com/product/fabric-scale-tf120/
perspiration fastness tester test method includes AATCC, ISO, DIN, GB and etc ISO 105
