Title:
FIBER HOLDER AND FIBER COLOR MEASURING METHOD
Document Type and Number:
WIPO Patent Application WO/2024/042934
Kind Code:
A1
Abstract:
This fiber holder comprises a support having a support surface that supports fibers subjected to color measurement, and a pair of protrusions provided on the support. The support surface is disposed between the pair of protrusions, and the fibers are disposed between the pair of protrusions so as not to go over the tops of the pairs of protrusions. The reflectance on the support surface with respect to light having wavelengths of 450 nm, 550 nm, and 650 nm is at least 60%, the luminous reflectance Y of the support surface is at least 60 (where the light source is a CIE standard light source D65, and the field of view is 10°), and the heights of the pair of protrusions with respect to the support are 1-3 mm.
