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.

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.

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.

Thermochromic cellulose fibers
Polymers for Advanced Technologies, 2007AbstractA method of obtaining thermochrome cellulose fibers has been developed. The basis technology used to form fibers was the Lyocell process. This method is based on spinning fibers from concentrated solvents of cellulose, using dry‐wet method in aqueous solidification bath. The cellulose solvent used in this process was N‐oxide‐N‐methylomorpholine

Trimethylsilyl cellulose as precursor to regenerated cellulose fiber
Journal of Applied Polymer Science, 1981AbstractTrimethylsilyl cellulose (TMSC) has been found to melt at 320–340°C in the absence of oxygen. When TMSC is prepared from chemical cellulose, using hexamethyldisilazane and a catalytic amount of chlorotrimethylsilane/pyridine in dimethylformamide, a thermoplastic material is obtained which may be melt spun into a fiber.

Dissolution of Cellulosic Fibers: Impact of Crystallinity and Fiber Diameter
Biomacromolecules, 2018With the aim of informing the selection of biomass pretreatment options and to assist in interpreting experimental results from different biomass/solvent combinations, this study addresses the impact of crystallinity and size on the kinetics of semicrystalline cellulose fiber swelling and dissolution.

AbstractCellulose fibers treated with different coupling agents based on trichloro‐s‐triazine have been evaluated in terms of their reinforcement effect on unsaturated polyesters. The treatment with coupling agents containing double bonds resulted in what we believe to be the formation of covalent bonds between fiber and matrix.

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.

Regenerated Cellulosic Fibers and Their Implications on Sustainability
2014This chapter discusses the present scenario and market trend of regenerated cellulosic fibers, and the properties of principal fibers existing in the market as well as some new fibers recently developed and yet to be explored. Production technologies of these fibers are discussed and their potential applications are presented.

Utilization of Purified Cellulose in Fiber Studies
1990Purified cellulose-type fiber products are widely used in experimental nutrition. Their use in a broad spectrum of studies may potentially lead to the acceptance of the misconception that the various commercially available cellulose products are equivalent. In this paper we have attempted to show that this is not the case.
