Application
The Standard Dry-Cleaning Machine is specifically designed for conducting physical index tests on various fabrics and garments after they are washed with detergent or organic solvent and dried in an oven. This machine is the only model that fully complies with all major dry-cleaning standards, accurately simulating the standard dry-cleaning conditions.
Testing Method
Test Principle
The Fabric Dimension Variance Rate test measures the dimensional stability of fabric after dry cleaning, specifically assessing shrinkage or elongation caused by dry cleaning with tetrachloroethylene. This test simulates repeated dry-cleaning cycles (usually not more than 5 times) to determine how garments hold up to the cleaning process.
Test Sample Preparation
- Garments are tested as they are.
- The sample size should not be less than 500mm x 500mm.
- Fabric edges must be wrapped with polyester yarn to prevent edge stripping.
- Ensure the sample is placed flat and tension-free for accurate measurement.
- Samples should be conditioned at 21°C (±1) and 65% relative humidity (±2) for at least 24 hours before testing.
Test Procedure
- Moisturize Samples: Immerse the sample in the mixture of Span80 and tetrachloroethylene, maintaining the solvent temperature at (30±3)°C.
- Emulsion Preparation: Turn off the filter path and start the dry-cleaning process, adding the emulsion slowly.
- Operation: Run the machine for 15 minutes without the filter path engaged.
- Solvent Removal: Centrifuge the sample for 2 minutes to remove excess solvent, then rinse with tetrachloroethylene for 5 minutes.
- Drying: Dry the sample at temperatures not exceeding 80°C. After drying, blow ambient air for 3-5 minutes to cool the sample.
- Post-Treatment: Measure the change rate in fabric size after post-treatment.
