AATCC 130:2018 pdf download.Soil Release: Oily Stain Release Method
1.1 This test method is designed to measure the ability of fabrics to release oily stains during home laundering.
1.2 This test method is primarily for use by fabric finishers to evaluate the likely performance of soil release finishes in actual use (see 12.1). If this test method is used as part of a contract between buyer and seller, or in any case where comparisons between laboratories are being made, the parties should agree to use the same ballast and detergent. In refree situations, or where standard specifications are involved. 1993 AATCC Standard Rekrence Detergent or 2003 AATCC Standard Reference Liquid Detergent WOB should be used (see 12.8 and 12.13).
1.3 The use of this test on garments is not precluded.
2. Principle
2.1 A stain is applied to a test specimen. An amount of the staining substance is forced into the fabric by using a specified weight. The stained fabric is then laundered in a prescribed manner and the residual stain rated on a scale from 5 to I by comparison with a stain release replica showing a graduated series of stains.
3. Terminology
3.1 soil n.- dirt, oil or other substances not normally intended to he present on a substrate such as a textile material.
3.2 soil release, n.-thc degree to which a soiled substrate approaches its original, unsoiled appearance as a result of a care procedure.

4. Safety Precautions
NOTE: These safety precautions are for information purposes only. The precautions arc ancillary to the testing proce dures and are not intended to be all inclusive. It is the user’s responsibility to use safe and proper techniques in handling materials in this test method. Manufacturers MUST be consulted for specific details such as material safety data sheets and other manufacturer’s recommendations. All OSIIA standards and rules must also be consulted and followed.
4.1 Good laboratory practices should be followed. Wear safety glasses in all laboratory areas.
4.2 The 1993 AATCC Standard Reference Detergent and the 2003 AATCC Standard Reference Liquid Detergent WOB may cause irritation. Care should be taken to prevent exposure to skin and eyes.
