As the drycleaning industry attempted to return to normality, it is time to check the drycleaning quality. We would want to know that we are returning the garment to a new and original condition ready for wearing. The drycleaned garment should be bright, white and free of stains. There are many ways the drycleaner can check the quality of the drycleaning system. The drycleaner must be aware of factors that contribute to redepostion.
- White cotton fabric test
Run a white cotton fabric in a light load. Compare it to the uncleaned fabric for graying, difference in color and redepostion.
- Silk fabric test
Run a small silk fabric in a drycleaning load. If the fabric becomes badly wrinkled, it is a sign of moisture.
- Solvent color
The color of the working tank should be amber color of beer but no darker.
- Cloudy Solvent
Cloudy or milky solvent means water is present.
- Solvent temperature
The higher the solvent temperature, the higher the chance is for dye bleeding, wrinkling and redeposition. Over 90℉ means hot solvent.
- Filter pressure
If the pressure is too high, it means the filters are clogged. If the pressure is too low, it means a hole in the filter or a faulty pump.
- Solvent flow
Check the time it takes to fill the wash wheel with solvent through the filters. If it takes more than one minute, you have a poor solvent flow.
Classify according to color and fabric. Remember red, vivid color, suede, leathers and spandex blended fabrics are bleeding problems.
