A press-bonded body or a method for producing the same is provided, such that the press-bonded body is a press-bonded body of at least one of a base material selected from the group consisting of non-woven fabric, stretched porous film, and fiber. The base material contains a fluorine resin (except for polytetrafluoroethylene) having a —CF2- group content of 85% by mass or greater. Polytetrafluoroethylene fibrils bond fibers constitute the base material, and in relation to the entirety of the fibrils, the proportion of the number of fibrils that are oriented at an angle of 45° to 90° relative to the direction of the fibers constituting the base material is 50% or greater.

According to one embodiment, a fiber sheet includes a plurality of fibers. The plurality of fibers are in a closely-adhered state. All of the following (1) to (3) are satisfied, where F1 is a tensile strength in a first direction, and F2 is a tensile strength in a second direction orthogonal to the first direction: (1) F2>F1; (2) F1 is 1 MPa or more; and (3) F2/F1 is 2 or more.

Methods are directed to the use of a supercritical fluid for finishing a target material with a finishing material. One or more variables selected from temperature, pressure, flow rate, and time are manipulated to increase efficiencies in the finishing process. As temperature or pressure are decreased causing a change in the density of a supercritical fluid carbon dioxide, which in turn causes a precipitation of dissolved material finish with the carbon dioxide, other variables are maintained above threshold values to increase the uptake of the material finish by the target material. This improvement reduces time by limiting cleaning processes of the system, saves materials used in the cleaning process, and saves energy used to achieve cycles of the process, in aspects.
