The spinning fiber reaches its final velocity/final denier when the stress applied to the spinning filament is no longer sufficient to draw the fiber to a smaller diameter. Solvent evaporation proceeds from the fiber surface inwards, often leading to a skin-core structure with trapped solvent in ...
The fibers are typically between 10 and 50 μm in length. In the meltblown process, hot air is blown onto the polymer before cooling, which makes it possible to shrink the size of the fibers (0.6–10 μm). The diameter and properties of the fibers that are formed are strongly ...
1. A yarn formed of elastane fibers produced from polyurea polyurethane by dry spinning or wet spinning to form filaments, removing the spinning solvent, finishing, optionally twisting to form filaments, and winding the spun filaments, wherein ...

PURPOSE:To eliminate the gluing of fibers, and to stabilize the spinning step, by extruding a spinning solution of an acrylonitrile polymer into an inert gas, and by introducing the fiber bundle into a coagulant containing a surfactant. CONSTITUTION:A spinning solution of an acrylonitrile polymer ...
