The oxidized sodium carboxymethylcellulose (O-CMC) fibers have been successfully synthesized via the oxidation-etherification method. Subsequently, the O-CMC fibers are characterized by Fourier transform infrared (FT-IR), 13C nuclear magnetic resonance (13C-NMR) and X-ray diffraction (XRD).

Anisotropic Viscosities of Oriented Discontinuous Fiber Laminates
Journal of Composite Materials, 1992Two theories have been compared for the prediction of the effective vis cosities of laminates made up of layers of oriented discontinuous fiber assemblies sus pended in a viscous fluid. In the first theory, the layers are constrained to exhibit identical strain-rate components, while in the second theory the individual layers are assumed to be ...

Enzymatic treated viscose fibers functionalized by chitosan
TAPPI Journal, 2018Our research focused on the sorption properties of enzymatically treated viscose/chitosan and viscose fibers treated with enzymes and chitosan. To improve sorption properties of viscose fibers and to obtain the characteristics similar to viscose/chitosan fibers, we performed two different treatments.

Enlarging of an optical fiber preform with viscose silica fiber
Journal of Non-Crystalline Solids, 1994Abstract Visil is a viscose silica fiber invented by Kemira Oy, Finland. The fiber contains up to 30% silica. The sodium and iron ions can be washed away from the fiber. When applying it to optical fiber preform production, the VISIL fiber is wound around the preform after which the preform is heated to remove organic material.

Thermal properties of flame retardant viscose fibers
Journal of Thermal Analysis, 1980This paper discusses the problem of the thermal properties of flame retarding additives based on phosphazene derivatives and of the commercial agents TomflamB, FlammexT23P and StockhausenW-20949, as well as of flame resistant viscose fibers containing the above agents.

Degradation of viscose fibers during acidic treatment
Cellulose, 2015Novel developments in the fiber sector require additional investigation of their behaviour during the production process. In the core step of the viscose process, cellulose fibres are regenerated in an acidic spinning bath. To investigate the influence of hemicellulose content and temperature on the kinetics of fiber degradation, standard and ...

Viscosity of fiber preloads affects food intake in adolescents
Nutrition, Metabolism and Cardiovascular Diseases, 2009Dietary fiber that develops viscosity in the gastrointestinal tract is capable of addressing various aspects of food intake control. The aim of this study was to assess subsequent food intake and appetite in relation to the level of viscosity following three liquid preloads each containing 5 g of either a high (novel viscous polysaccharide; NVP ...

Investigating the Biodegradation Potential of Viscose Fiber
2023Fibres are considered biodegradable when they can be naturally decomposed, either in the presence of oxygen (aerobically) by microorganisms into carbon dioxide, water, mineral salts, and biomass, or in the absence of oxygen (anaerobically) into carbon dioxide, methane, mineral salts, and biomass.

Carboxymethylcellulose (CMC) fibers have been successfully prepared from viscose fibers through the process of alkalization-etherification. Parameters including reaction temperature, mass ratio of NaOH to the viscose fibers, and mass ratio of the viscose fibers to ethanol are studied.
