"If you don't know where you are going, any road will get you there."
- Lewis Carroll in "Alice in Wonderland"
Either one of these famous quotes summarizes the textile industry's current approach to oleophobic fabric finishing. Having lost the industry staple, "C8" fluorocarbon, there are now any number of other approaches to oleophobic (oil-repellent) fabric finishing. Many are far inferior to C8, and there is much general confusion as to which to use.
The key is to know where you want to go - and then to take the right road. If rain protection is needed and oil repellency just seems like a nice add-on... perhaps better results will be obtained using our hydrocarbon-based, Evergreen™ technology. Surprisingly, adding oleophobic protection can actually make water repellency worse!
GTT's approach is to match the technology to the customer need, rather than to make a "one-size fits all" chemistry. If the product is disposable, nonwoven hospital gowns intended for worker protection... perhaps an fluorocarbon-based C6 add-on treatment is sufficient. Contact us for details on how to obtain oleophobicity using our water-free finishing technology.
All of our oleophobic treatments: 1) use our proprietary dry finishing technique, 2) are PFOA-free, 3) may be either thermally or plasma-cured, and 4) are also hydrophobic. Contact us for further information.
