Processing fiber spinning

Fiber processing, spinning, dry In dry spinning a plastic solution is extruded (metering pumped) through a spinneret. The filaments exit the spinneret through a gas-heated cabinet where the solvent is rapidly removed from the plastic filaments. The suitable solvent is filtered and recovered for further use in-line. Filaments end up at the driven haul-off roll. 

Fiber processing, spinning, jet For most purposes this process is similar to fiber spinning. Hot gas jet spinning uses a directed blast or jet of hot gas to pull molten plastic from a die lip and extending it into fine fibers. 

Fiber processing, spinning, raw nucleation The mechanism by which stress-induced crystallization is initiated usually during fiber spinning or hot drawing. 

Fiber processing, spinning, reaction A liquid polymer is extruded through a spinneret plate and encounters a chain extending cross-linking component producing a filament.
