Textile Instruments Perspiration Color Fastness Test ISO 105
Perspirometer
Application
Perspiration Tester to determine colour fastness test to water, sea
water, perspiration fastness in textiles and sublimation during
storage. Perspiration tester consists of 2 stainless steel frame
with 21 acrylic separator plates to hold 20 samples. Thus the both
ISO/AATCC test methods can be done in one time. 20 plastic basins
are equipped for pre-treatment of samples.
A precise oven is required.
Color Fastness of dyed or printed fabrics against perspiration is
determined by exposing the fabric sample to the action of both
alkaline and acidic reagents while in contact with undyed adjacent
fabrics is placed between plastic plates under a fixed load inside
an oven maintained at 370 centigrade. The apparatus used for this
test is called the Perspirometer.
consists of a number of acrylic plates and which can be kept in
suitable loading frame. The loading frame consists of two steel
plates between which the acrylic plates placed. The test specimen
are stitched between suitable white cloth pieces and dipped in
either alkaline or acidic test solutions.

Principles
To test colour fastness to perspiration, specimens (fabric, yarn or
fiber) in contact with multifiber fabric are treated in two
different solutions. One solution is acid and one solution is
alkaline. The specimens are subsequently drained and placed under a
specific load between the separator plates. The units are placed in
an oven for a pre determined length of time, after which time the
units are removed from the oven. The specimens are removed from the
separator plates and placed in an oven/incubator to dry after which
they are assessed with grey scales.
Note for testing colour fastness to cold water, the same apparatus
is used and the solutions are substituted for distilled water.

Preparation of test solutions
Solutions should be made up immediately prior to use as the
chemicals can degrade over time.
- Alkaline solution (makes 1 Litre)
0.5 g of l-histidine monohydrochloride monohydrate
(C6H9O2N3.HCl.H2O)
5 g of sodium chloride
(Na Cl) either
5g of disodium hydrogenorthophosphate dodecahydrate
or 2.5 g of disodium hydrogen orthophosphate dihydrate
The solution is brought to pH 8.0 with 0.1 mol sodium hydroxide
solution.
- Acid solution (makes 1 Litre)
0.5 g of l-histidine monohydrochloride monohydrate
(C6H9O2N3.HCl.H2O)
5 g of sodium chloride
(Na Cl)
2.2 g of sodium dihydrogen orthophosphate dihydrate(NaH2PO4.2H2O)
The solution is brought to pH 5.5 with 0.1 mol sodium hydroxide
solution.

What is perspiration fabric?
Perspiration fastness refers to the ability not to fade and not to
stain when dyed fabric is perspired. People's sweat consists of
complicate composition, and its main composition is salt. Sweat is
divided into acidity and basicity due to difference of people.
