, 2021 Cellulose is environmentally friendly material that has brought new possibilities for light guiding and manipulation. Regenerated cellulose fibers and methylcellulose fibers have been demon-strated. These optical fibers are not competing in optical telecommunication with glass optical fiber and polymer optical fibers.

Cellulose fibers as Reinforcement in Composites: Determination of the stiffness of cellulose fibers
Composites Science and Technology, 1986Abstract A new method for the determination of the elastic modulus of cellulose fibers is presented. Cellulose fibers separated by different pulping processes were fractionated in order to get the same aspect ratio. Composites were prepared under well-controlled conditions, by impregnating unoriented, laboratory-made handsheets with liquid ...

Adhesion of cellulose fibers in paper
Journal of Physics: Condensed Matter, 2012The surface topography of paper fibers is studied using atomic force microscopy (AFM), and thus the surface roughness power spectrum is obtained. Using AFM we have performed indentation experiments and measured the effective elastic modulus and the penetration hardness as a function of humidity.

AbstractThe temperature dependence of the brittleness of cellulose fibers was studied by the breaking twist angle method. The selected fibers were purified ramie cells, the same cells after fibrous acetylation to form the triacetate, annealed acetylated ramie cells, and mercerized ramie cells.

AbstractRuland's concept of an isotropic disorder function is applied to estimate the disorder parameter and the degree of crystallinity in a few cellulosic fibers: two cottons, native ramie, and a high‐tenacity rayon. The results indicate an increase in disorder without any change in crystallinity on mercerization of native celluloses.

Although the term “cellulosic fibers” is frequently used, the type is massively dominated by cotton. Other fibers which have been embodied as cellulosic are viscose rayon, linen, cuprammonium rayon, and jute and these can be dyed with dyes related to those used on cotton. Paper and leather can also be dyed similarly.
