Oil and stain resistance are desirable attributes of fabrics—in the garments we wear to protect us, well, against ourselves! Everyone drops, spills, or sits on some type of soil medium at some point in time. While these “accidents” are harmless, they can be the source of angst when the soil medium stays on the fabric as a stain. Sometimes, stains that can’t be removed may cause the garment to no longer be used and, ultimately, discarded.

Oil Repellency: Hydrocarbon Resistance
The textile industry needed a test to detect the performance of the soil release finishes. The test for judging how well a finish performed was developed by A-A-T-C-C’s Committee on Stain Resistance; it’s called RA 56, Test Method 118. Oil Repellency: Hydrocarbon Resistance, has been edited, reaffirmed and used since 1966.
Soil Release: Oily Skin
Being able to figure out whether or not a fiber, fabric or finish stained by an oily soil medium can be removed in laundering is a desirable attribute that a consumer can see.
Stain Release: Grass/Other Soils
Stain release performance after laundering became an important function because the textile-finishing chemistries that were used to create smoothness appearance and dimensional stability also create an affinity for retaining oily stains.
