FTTS-FA-012　Oil Repellent Textiles

Oil Repellent Textiles resist oil penetration. Essentially they are fabrics, either natural or synthetic fibers, that have been saturated with an oil repellent agent. Oil Repellent Textiles are found in apparel, work clothing, furniture coverings and home textiles and more. They find applications anywhere fabric is at risk of contacting oil products.

 

Taiwan technology for Oil Repellent Textiles earns not less than grade 4 initially, and after 100 launderings maintains at least grade 3 on an 8-point grade. The test method employed is AATCC 118.

Scope

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.
