  1. PURPOSE AND SCOPE:

    This method is designed to measure the ability of a fabric (which has been treated with soil release finish) to release stains during home laundering. This test method can also be used for evaluating effectiveness of laundry detergents and cleaners.
  2. PRINCIPLE:

    The various types of stains, as requested, are applied on the garments. After laundering, the degree of remaining stains are visually evaluated by comparing against AATCC standard replica.
  3. REFERENCE:

    AATCC Test Method 130-2010, Soil Release: Oily Stain Release Method.
  4. APPARATUS:

  5. PROCEDURE:

  6. EVALUATION:

    Compare the residual stains on the specimens with the stains in the AATCC standard stain release replica and assign a grade as follows:

    GRADE Standard
    Grade 5 Stain equivalent to Standard Stain 5
    Grade 4 Stain equivalent to Standard Stain 4
    Grade 3 Stain equivalent to Standard Stain 3
    Grade 2 Stain equivalent to Standard Stain 2
    Grade 1 Stain equivalent to Standard Stain 1

    Grade 5 represents the best stain removal and Grade 1 the poorest stain removal.
  7. REPORT:

    Calculate the average of 4 grades for each fabric (2 judgments on each of 2 specimens) to the nearest 0.1. This is the unit of measure for this test method.
  8. NOTE:
