Stabilization of fabric surfaces

A textile fabric having improved properties, variously including surface stability, abrasion resistance, resistance to edge fraying, moisture control, and resistance to fluid penetration is created by introducing a polymeric solution or a plurality of low-melting particles suspended in a liquid into the textile fabric while leaving a plurality of surface fibers exposed and maintaining a textile feel on the surface.

Method of producing resin frame member for fuel cell and processing die

In a method of producing a resin frame member for a fuel cell, a processing die is used. The method includes a processing step of moving an upper die toward a lower die to thereby form an inclined surface on each of side parts of a resin film. In the processing step, shearing is performed while maintaining a predetermined clearance between the lower processing section and the upper processing section and in a state where each of the side parts is at least partially positioned at a cutout so that each of the side parts is inclined downward toward the inside. The cutout is formed by cutting off an edge part of a placement surface that is positioned on the lower processing section side.
