What is sublimation fastness tester?

Scorch Tester Sublimation Fastness Tester apply to textile assist color change or transfer capacity under heating condition, simulate textile being ironing and under high temperature & humidity dyeing color fastness to sublimation degree in daily life.

Features of Sublimation Fastness Tester

01

Testing the effect of direct heat on the dyestuff.
02

Up to 250°C temperature range. 3 pairs, 6 heat pads. 10 to 60 seconds contact timer.
03

Individual 3 temperature controllers with sensors.Upper and lower heat board control temperature separately , accurate temperature control, timing alert, control testing time exactly.

04

Can test entire range of temperature in a single test. Individual 6 temperature controllers with sensors.
05

Single work station easy for operation, high cost performance, Multi work station type can raise the efficiency and also meet M&S standard.
06

Heating board distance is adjustable, suitable for specimen of different thickness, high efficient insulation material ensures the safety operation.

Features of Sublimation Fastness Tester

◪1. Scorch & Sublimation Tester equip with digital temperature controller, customer can set test temperature according to requirements.
◪2. Equipped with digital timing controller, can control heating time strictly.
◪3. Scorch and sublimation tester can do textile test under three conditions, they are:
(1) Dry Pressing: The dry specimen is pressed with a heating device of a specified temperature, time and weight;
(2) Damp Pressing: The dry specimen is covered with a wet, undyed cotton cloth and pressed with a heating device of a specified temperature, time and weight;
(3) Wet Pressing: The wet specimen is covered with a wet, undyed cotton cloth and pressed with a heating device of specified temperature and weight.

How Sublimation Fastness Tester Works?

1. 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.

2. The fabric pieces should be picked up immediately. The undyed fabric pieces will be stained by the dyes.

3. This gives the sublimation fastness properties for the range of temperature 130°C to 250°C in one test.

4. A ready comparison of sublimation fastness properties at various temperatures is hence available.
