The present disclosure addresses the problem of providing a method for imparting liquid repellency to fibers even when the amount of water and/or a surfactant is reduced, preferably without using water and/or a surfactant. Provided is a method for producing liquid-repellent fibers, the method comprising a fiber treatment step in which supercritical carbon dioxide is used as a treatment medium and a fiber base material is treated with a repellent containing a liquid-repellent compound, whereby liquid repellency can be imparted to the fibers even when the amount of water and/or a surfactant is reduced, preferably without using water and/or a surfactant.

The novel flexible electrodes disclosed herein utilize the low bending stiffness of electrospun nanofiber mats to achieve the material properties required for surgical implantation and sustained bidirectional communication with peripheral nerves without compromising electronic functionality. According to certain embodiments disclosed herein, implantable neural electrode probes are provided which comprise a polymeric substrate having proximal and distal ends, an electrode interface at the proximal end of the substrate; at least one neural contact at the distal end of the substrate; and electrically conductive traces formed on the fibrous substrate providing electrical communication between the at least one neural contact and the electrode interface, wherein the substrate comprises a nonwoven mass of polymeric nanofibers.

A barrier fabric suitable as a backsheet for an underpad configured for a low air loss bed, in which the barrier fabric comprises a first nonwoven fabric including outermost spunbond layers and two or more fine-fiber containing nonwoven layers. Each of the nonwoven layers being treated with a non-fluorinated barrier coating (NFBC).

A textile treatment emulsion formulation includes a silicone-(meth)acrylate copolymer, a surfactant, water and a blocked isocyanate and method for its preparation are disclosed. The textile treatment emulsion may be used in a method including coating the emulsion formulation on a textile and heating the textile to dry the emulsion formulation. This method renders the textile oil repellent.
