Application
The Scorch Tester (Sublimation Fastness Tester) evaluates the color fastness and dimensional stability of fabrics under hot, dry conditions. It determines resistance to ironing and sublimation, ensuring high-temperature durability and color retention. Equipped with an adjustable heating plate temperature and test time, the device features a microprocessor temperature controller and a top plate with precisely controlled weight. Independent heating plates allow for individual control of test temperature and sample thickness.
Standards
- ISO 105
- BS 1006
- AATCC 92/114/117/133
- DIN 54022/54060
- JIS L0879/L0850/L0879
- GB/T 5718/6152BS EN 14878
- BS 5438 1989
Testing Method
- Turn on the power.
- Select the desired mode (ironing or sublimation). The corresponding indicator lamp flashes to signal heater activation.
- Set the test temperature according to the fiber type, garment material, or structure.
- Adjust the test time, typically 15 seconds under specified pressure and temperature.
- Once the temperature is reached, place the sample in the heating box:
- Dry pressing: Heat the dry sample directly without lining fabric.
- Tidal pressing: Cover the dry sample with a wet cotton-lined fabric.
- Wet pressing: Cover the wet sample with a wet cotton-lined fabric.
- Lower the heating plate, applying 4kPa pressure, and press the Start button.
- After the set time, lift the heating plate.
- Immediately assess color change using the corresponding gray sample card.
- Re-evaluate the sample after 4 hours in standard atmospheric conditions.
Results
- Discoloration assessment: Gray sample card 250
- Staining evaluation: Gray sample card 251
