This invention relates to polyester-based fibrous substrates being surface coated at least partially with a coating composition comprising perfluoropolyethers. Processes of application of the coating compositions are also provided. The polyester-based fibrous substrates after surface coating have improved wear and/or abrasion resistance relative to uncoated fibrous substrates.

Fibers sized with a coating of amorphous polyetherketoneketone are useful in the preparation of reinforced polymers having improved properties, wherein the amorphous polyetherketoneketone can improve the compatibility of the fibers with the polymeric matrix.

The present invention relates to a medical device. In particular, the present invention concerns a medical device which can be detected by means of magnetic resonance imaging (MRI).

Electrically conductive synthetic fiber and fibrous substrate (e.g. synthetic leather) are disclosed. The electrically conductive polymeric fiber and polymeric fibrous substrate are made electrically conductive by the use of an electrically conductive polymer disposed on the fibers and in contact with inorganic desiccant particles located at the surface of the fibers. The new material finds utility as an electrode for devices and as a resistive heating element, and as a pathway to efficient thermoelectrics.
