Sublimation
Fastness Tester is a suitableinstrument for dyestuff manufacturers as well
as textile
processors for checking effects ofdry heat on dyestuff.
ð Sublimation fastness and staining effect properties
of individual dyes can be tested at various temperatures.
ð In a single test, entire range of effective
temperature can be tested. The heating pads are made up of hard chromed electrolyte copper for even and quick distribution of heat.
A = Upper Pad (With Undyed Fabric)
B = Specimen Pad
C = Temeprature Indicator (Digital)
ð Testing the effect of direct heat on the dyestuff.
ð 120°C up to 250°C temperature range.
ð 10 to 60 seconds contact timer.
ð Individual temperature controllers with sensors.
Specifications
of Sublimation Fastness Tester:
Temperature range for test
|
: 120°C up to 250°C
|
Temperature settings
|
: 150°C, 180°C & 210°C
on each pad or variable temp setting.
|
Power readout
|
: Digital display for each
pad.
|
Size of each pad
|
: 40 mm x 100 mm.
|
Timer range
|
: 10-60 sec.
|
Working
|
ð A dyed cloth piece is sandwiched between two undyed
pieces and placed to cover the heat pads and the test goes on for a pre-set
time period.
ð The fabric pieces should be picked up immediately.
The undyed fabric pieces will be stained by the dyes.
ð This gives the sublimation fastness properties for
the range of temperature 130°C to 250°C in one test.
ð A ready comparison of
sublimation fastness properties at various temperatures is hence available.
