Abstract
A method for producing a preparation for fiber length measurement includes: a preliminary dispersion process of adding fibers and a dispersion medium with a viscosity of 500 Pa·s to 10,000 Pa·s to a sealable container so as to give a concentration of the fibers of 0.1% by mass or less and shaking the container to prepare a preliminary dispersion liquid; a dispensing process of dispensing part of the preliminary dispersion liquid to another sealable container; a dilution process of adding the dispersion medium to the dispensed preliminary dispersion liquid so as to give a concentration of the fibers of 0.005% by mass or less and shaking the container to prepare a dispersion liquid for measuring fiber length; and a casting process of spreading part of the dispersion liquid for measuring fiber length onto a base having light transparency.
