FTTS-FA-012 Oil Repellent Textiles
Oil Repellent Textiles resist oil penetration. Essentially they are fabrics, made of either natural or synthetic fibers, which have been saturated with oil repellent agent. Oil Repellent Textiles are found in apparel, work clothing, furniture coverings, home textiles…etc. They find applications anywhere fabric is at risk of contacting oil products.
With current technology in Taiwan, the initial oil repellency of Oil Repellent Textiles reaches grade 4 or above; having undergone 100 launderings, their oil repellency still reaches grade 3 or above (the test method employed is AATCC 118).
This criterion defines the evaluation and testing of oil repellency textiles. It is applicable to textiles finished with fluorochemical or other compounds capable of imparting a low energy surface.
