Modeling the Melt Spinning of Polyethylene Terephthalate
(Sage Publications Ltd, 2000-04)
A model is formulated to describe quantitatively the melt spinning of a polyethylene terephthalate (PET) within the low range of take up velocities. The rheology of the polymer melt is described with the Phan-Thien and ...
Microstructure and texture of duplex stainless steel after melt-spinning processing
(ELSEVIER SCIENCE INC, 2008)
The microstructure and texture of melt-spun UNS S31803 (DIN W. Nr. 1. 4462) duplex stainless steel were analyzed after casting and solution treatment. The cast ribbons contained austenite (gamma) and ferrite (alpha or ...
A Numerical method for the Viscoelastic Melt Spinning Model with Radial resolutions of Temperature and Stress Fields
(American Chemical Society, 2002-06)
A numerical method to compute the viscoelastic melt-spinning model with radial resolutions of temperature and stress fields is formulated and applied to the low speed range. The starting framework is the reduction of the ...

Modeling Melt Spinning with Stress Induced Crystallization at High Take Up Velocities: Numerical Results for the PET Melt
(Asociación Argentina de Mecánica Computacional, 2002-11)
The purpose of this work is to present a 2-D thermo-rheological model for high take up velocities that can predict numerically in the filament domain, the axial velocity profile together with the radial and axial resolutions ...
Computational Model for Non-Isothermal Melt Spinning Flows: The Low Take Up Velocity Range
(Asociación Argentina de Mecánica Computacional, 2002-11)
This work shows the interrelation between non-isothermal melt spinning flows and the isothermal extensional flow described through rheometry. This analysis uses the iterative numerical algorithm presented by Ottone and ...
A Rheological Study of Isotactic Metallocene-Based Polypropylene Resins and the Mathematical Modeling of the Melt Spinning Process-Edición Única
(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2000-12-01)
A comprehensive rheological study of metallocene-based isotactic polypropylene resins was conducted
and the materials were processed into fibers by the industrial melt spinning process. The study also
includes the standard ...
Structural and thermal characterization of dioctadecyldimethylammonium bromide dispersions by spin labels
(Elsevier B.V., 2001-06-01)
Dioctadecyldimethylammonium bromide (DODAB) dispersions obtained by simply mixing the amphiphile in water, and by bath-sonication, were investigated by electron spin resonance (ESR) of stearic acids and their methyl ester ...
