What is "Dry Spinning" - Definition & Explanation

Dry spinning uses a solvent that evaporates in air. The dissolved polymer is extruded through the spinnerette into a chamber of heated air or gas, the solvent evaporates, and the fibre forms. The solvent is generally recovered for reuse. Acrylic is produced by dissolving the polymer in dimethyl formamide before dry spinning. Other fibres formed by dry spinning include acetate, triacetate, spandex, and aramid. The evaporated solvent is drawn upwards by the air stream, for collection and recycling, but almost impossible to contain all solvent within system.
In the dry spinning process, polymer is dissolved in a solvent before being spun into warm air where the solvent evaporates. This leaves the fibrous polymer ready for drawing.
