Method for producing cellulose nanofibers
An object of the present invention is to provide an efficient method for producing cellulose nanofibers, without N-oxyl compounds such as TEMPO remaining in the cellulose nanofibers. Provided is a method for producing cellulose nanofibers, the method including: oxidizing a cellulose raw material with hypochlorous acid, or a salt thereof, having an available chlorine concentration of from 14% by mass to 43% by mass, to produce an oxidized cellulose; and fibrillating the oxidized cellulose into nanofibers.

NANOCELLULOSE COMPOSITIONS AND PROCESSES TO PRODUCE SAME
A composition comprising nanocellulose is disclosed, wherein the nanocellulose contains very low or essentially no sulfur content. The nanocellulose may be in the form of cellulose nanocrystals, cellulose nanofibrils, or both. The nanocellulose is characterized by a crystallinity of at least 80%, an onset of thermal decomposition of 300° F. or higher, and a low light transmittance over the range 400-700 nm. Other variations provide a composition comprising lignin-coated hydrophobic nanocellulose, wherein the nanocellulose contains very low or essentially no sulfur content. Some variations provide a composition comprising nanocellulose, wherein the nanocellulose contains about 0.1 wt % equivalent sulfur content, or less, as SO.sub.4 groups chemically or physically bound to the nanocellulose. In some embodiments, the nanocellulose contains essentially no hydrogen atoms (apart from hydrogen structurally contained in nanocellulose itself) bound to the nanocellulose. Various compositions, materials, and products may incorporate the nanocellulose compositions disclosed herein.
