AATCC 130-2018 Soil Release: 0ily Stain Release Method.
1.1 This test method is designed to measure the ability of fabrics to release oily stains during homc laundering.
1.2 This test method is primarily for usc by fabric finishers to evaluate the likely performance of soil release finishes in actual use (sec 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 referee situations, or where standard specifications arc involved. 1993 AATCC Standard Reference Detergent or 2003 AATCC Standard Reference Liquid Detergent WOLI should be used (sec 12.R and 12.13).
1.3 The use of this test on garmcnts is not precluded.
2. PrincIple
2.1 A stain is applied to a test specimen. An amount of the staining substance is torced 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 shong a graduated series of stains.
3. Terminology
3.1 MIII, n.—dirt, oil or other substances not normally intended to be present on a substrate such as a textile material.
3.2 soil release, n. —the degree to which a soiled substrate approaches its original. unsoiled appearance as a result of a care procedure.
3.3 stain, n—a local deposit of soil or discoloration on a substrate that exhibits some degree of resistance to removal, as by laundering or drvcleaning.
4. Safety Precautions
NOTE: These safety precautions are for information purposes only. The precautions are ancillary to the testing proce durcs and are not intended to be all inclusive. It is the users responsibility to use safc and proper techniques in handling materials in this test method. Manufacturers MUST be consulted for specific dctails such as ma(crial safety data shccts and other manufacturers recommendations. All ()SHA 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 Refercuce Detcrgcni and the 2003 AATCC Standard Reference Liquid Detergent W( )H may cause irritation. (‘are should be taken to prevent exposure to skin and eyes.
43 Manufacturers safety recommendations should be followed when operating laboratory testing equipment.
