Title:
CELLULOSE FIBERS, RESIN COMPOSITION, MOLDED ARTICLE, AND METHOD FOR PRODUCING CELLULOSE FIBERS
Document Type and Number:
WIPO Patent Application WO/2024/048626
Kind Code:
A1
Abstract:
Provided are a resin composition, a molded article, and a method for producing cellulose fibers. When dyed by a dye, the cellulose fibers have a ratio (L'/L) of the skin layer brightness (L') and the core layer brightness (L) of 0.70 or less. The skin layer brightness (L') and the core layer brightness (L) of the cellulose fiber cross section are obtained by measuring the R, G, and B values of each of the layers, and calculating using the formula of [(maximum value of the R, G, and B values)/255] * 100 [%].
