A nanofiber laminate sheet including a layer of a nanofiber of a water insoluble polymer and a layer of a water soluble polymer containing a cosmetic component or a medicinal component. The nanofiber is preferably colored. The layer of a water soluble polymer is preferably a layer of a nanofiber of the water soluble polymer containing the cosmetic component or the medicinal component. The nanofiber laminate sheet is suited for use as a cosmetic sheet for makeup.

Nanofiber laminate sheet

A nanofiber sheet including a nanofiber layer containing a polymeric nanofiber, a surface of nanofiber sheet being adhesive. The nanofiber preferably contains an adhesive component and a water insoluble polymer. The nanofiber sheet preferably has a water soluble layer containing a nanofiber containing a water soluble adhesive component and a water insoluble layer containing a nanofiber containing a water insoluble polymer laminated to each other. The nanofiber sheet preferably further includes a base layer located on one side of the nanofiber layer and an adhesive layer located on the other side of the nanofiber layer.

The present invention provides a method for manufacturing a film catalyst, including forming a catalyst layer on one side or each side of a base material to obtain a film catalyst, bending the film catalyst, and optionally cutting the film catalyst, wherein the bending step is conducted by bending the film catalyst with a bending tool composed of two gears that are oppositely arranged as meshing each other while a protective material having a compressibility of 40 to 95% is inserted between the catalyst layer of the film catalyst and the two gears.
