Procedure
- A test sample is clamped to the instrument base and a square of standard crocking cloth is fixed to a 16mm diameter, acrylic rubbing finger.
- The finger rests on the sample with a pressure of 900 grams force and traverses a straight path approximately 100mm long with each stroke of the arm.
- Established rating scales standardize evaluation and facilitate repeatable results.
- After testing textile materials, the crocking cloth is removed and compared against the AATCC Gray Scale for Staining or Chromatic Transference Scale.
- Based on this comparison, the operator assigns a grade to the color change or amount of color transfer
