dryspun
Dryspun refers to fibers produced by the dry spinning process, in which a polymer solution is extruded from a spinneret into air and the solvent rapidly evaporates to form solid filaments. The filaments then travel through a drying or air-gap chamber before being wound. This method is contrasted with wet spinning, where the dope enters a coagulation bath, and with melt spinning, which uses molten polymer without a solvent.
In a typical dry-spinning setup, a dope containing a soluble polymer and a volatile solvent is prepared
Common materials used in dry spinning include cellulose acetate and certain other synthetic polymers that form
Historically, dry spinning became prominent in the production of acetate fibers in the early to mid-20th century
