Structure and thermal properties of bamboo viscose, Tencel and conventional viscose fiber
Journal of Thermal Analysis and Calorimetry, 2007Comparative investigations of new regenerated cellulosic fibers, bamboo viscose fiber and Tencel, together with conventional viscose fibers have been carried out to explain the similarity and difference in their molecular and fine structure. The analyses jointly using SEM, XRD and IR reveal that all the three fibers belong to cellulose II.

Preparation and characterization of cyclotriphosphazenekeratin/viscose fibers
Fibers and Polymers, 2015The aim of this study is to develop a flame-retardant viscose fiber using the phosphazene derivative of a natural polymer. Hexachlorocyclotriphosphazene (HCCTP) and keratin were used as the raw materials to synthesize cyclotriphosphazenekeratin (CCTPK).

Reaction of Fire Retardants with Viscose Fiber
Fibre Chemistry, 2014IR spectroscopy, the calculated sorption coefficient for the reaction of viscose fiber with fire retardant, and the determined oxygen index of the modified fibers that characterized the flammability of the material were used to study the reaction of the fiber with dimethylmethylphosphonate derivatives.

Viscosity measurement using fiber bend loss sensor
2012 International Symposium on Optomechatronic Technologies (ISOT 2012), 2012A fluid viscosity sensor using bend loss theory is presented. The sensing principle makes use of the damping characteristic of a vibrating optical fiber probe with fix-free end configuration. By measuring the frequency response of the fiber probe, the viscosity can be determined from the displacement of the fiber. The physical and mathematical model of

Fibers and Polymers, 2013
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 ...
