Optical Fiber Probe for Viscosity Measurements
26th International Conference on Optical Fiber Sensors, 2018An optical fiber probe was developed for viscosity measurements. The sensor acts as a two-wave interferometer, sensible to the position of the fluid inside the cavity. Viscosity is measured through the fluid evacuation velocity.

Fire-Resistant Viscose Rayon Fiber Materials
Fibre Chemistry, 2016The possibility of directly controlling the structure and properties of viscose rayon fiber materials is considered here in the modification with flame retardants and fire retardant systems. The dependence is shown of the degree of crystallinity, the physicomechanical properties, and thermolysis and combustion indicators of the materials on their ...

"Polykon'' mosaic membranes reinforced with viscose fiber
Proceedings of the International Scientific and Technical Symposium «Improving energy and resource efficiency and environmental safety of processes and devices in the chemical and related industries» dedicated to the 110th anniversary of A. N. Planovsky : Vol. 2, 2021Some features of fabrication of "Polykon" mosaic membranes obtained by the "from anionite to cationite" technology are considered. The results of an experimental study of the physical and mechanical properties of a material as an object of ionic transfer are presented.

Design of viscosity-matched optical fibers
IEEE Photonics Technology Letters, 1992An optical fiber with a homogeneously viscous cross section can be designed for an arbitrary index profile by utilizing two kinds of dopant which have different effects on host material viscosity. Examples of designs are shown for silica-based fibers when GeO/sub 2/ and F are used as the dopants. >

Viscosity of curved fibers in suspension
Journal of Non-Newtonian Fluid Mechanics, 2002In this paper, the relationship between fiber shape and relative viscosity of a fiber suspension is explored. A numerical simulation has been used to model non-Brownian curved rigid fibers in suspension under the influence of Newtonian shear flow. Curvature in the simulated fibers was taken to represent general deformities of real fibers in suspension.

Tuning hardness of swollen viscose fibers
Bioinspired, Biomimetic and Nanobiomaterials, 2014Viscose fibers are man-made, regenerated cellulose fibers. They offer versatile uses ranging from hygiene articles to textiles and medical applications. The great advantage over natural pulp and cotton fibers are the possibilities to design the fibers’ cross-sections and modify the material by directly mixing additives to the viscose dope.

Viscosity as Related to Dietary Fiber: A Review
Critical Reviews in Food Science and Nutrition, 2006Viscosity is a physicochemical property associated with dietary fibers, particularly soluble dietary fibers. Viscous dietary fibers thicken when mixed with fluids and include polysaccharides such as gums, pectins, psyllium, and beta-glucans. Although insoluble fiber particles may affect viscosity measurement, viscosity is not an issue regards insoluble

Non-newtonian viscosity of fiber suspensions
Mechanics of Composite Materials, 1991It has been established that the introduction of fibers not only increases the viscosity of the matrix (a Newtonian liquid), but also leads to dependence of the viscosity on the shearing stress a viscosity anomaly [1-3]. At certain concentrations of monodisperse fibers and with certain viscosities of the matrix, a viscosity "superanomaly" has appeared,

The viscosity of fiber suspensions at low fiber volume fractions
Polymer Engineering & Science, 1981AbstractThe viscosities of suspensions of glass fibers in an aqueous solution of sucrose have been studied by use of a capillary viscometer. In the aligned condition in the capillary, the viscosity depends little on shear rate within the range studied or on fiber length, but increases with increasing volume fraction of the fibers.

Viscosity-matched single-mode fibers
1999 IEEE LEOS Annual Meeting Conference Proceedings. LEOS'99. 12th Annual Meeting. IEEE Lasers and Electro-Optics Society 1999 Annual Meeting (Cat. No.99CH37009), 2003We reviewed the viscosity characteristics and scattering characteristics of silica glasses. We also reviewed the viscosity-matching technique. This technique is very promising for realizing low-loss fiber where the difference between core and cladding viscosities is relatively large.
