OLEOPHOBIC COATINGS AND WIPES AND APPLICATORS USED TO PRODUCE THEM
Certain embodiments described herein are directed to wipes and coating materials that can be used to provide an oleophobic surface coating on one or more surfaces of an article. In some examples, the wipe may retain the coating material and can transfer at least some of the coating material to a surface where it can be heat cured to provide the oleophobic coating. In some instances, the wipe can provide an oleophobic surface coating with easy-to-clean performance for at least one cycle and up to ten cycles.

TUNING SURFACE PROPERTIES OF MELT BLOWN POLYESTER FIBERS BY HYDROLYSIS AND SOLUTION GRAFTING
Described herein is a continuous process fear modifying the properties of polyester and polyester based fibers, such as a poly(butylene terephthalate) (PBT) fiber, comprising subjecting the PBT fiber to alkaline hydrolysis, and optionally further comprising functionalizing the PBT fiber by solution grafting such as fluorination. The alkaline hydrolysis and optionally subsequent functionalization such as fluorination process can be continuous, following the melt blowing/spinning or spun-bonding process. Also described is a nonwoven PBT fiber mat obtained by the surface modification process. Further described is a filtration device comprising the nonwoven PBT fiber mat.
