Abstract

Here we propose a new physical approach to the high-speed conformation of a Newtonian viscous liquid into a fiber (high speed fiber drawing), which suppresses all well-known axisymmetric and asymmetric instabilities during the fiber drawing. Our approach is based on the application of an appropriate gas pressure profile along the viscous jet or fiber axis, provided by a special subsonic micro-nozzle concentric with the fiber. The micro-nozzle design and optimization is mathematically provided.
