Abstract:
Nanofiber that keep crystallinity are obtained from a cellulose material under light load. The nanofiber are obtained by treating a material containing cellulose with 4% by mass or more and 9% by mass or less of an aqueous alkali metal hydroxide solution to produce alkali cellulose, reacting the alkali cellulose with carbon disulfide to give cellulose xanthate, and defibrating the cellulose xanthate. Then, the xanthate is treated with acid or heat to be regenerated into cellulose nanofiber.

Claim (Index 5):
The cellulose xanthate nanofiber according to  claim 4 , having an average degree of xanthation of 0.1 mol % or more and 33.3 mol % or less, an average fiber length of 2 \u03bcm or more and 100 \u03bcm or less, and an average fiber diameter of 3 nm or more and 250 nm or less.
