Abstract
Method for removing gaseous monomer emitted during the manufacture of polymer fibers include collecting the gaseous monomer in a suction nozzle constructed of smooth polymeric material having low heat conductivity to avoid monomer buildup therein and delivering same upwardly through a water trap to a transport duct which is kept sufficiently wet to receive and remove monomer solids carried in the water which flows by gravity in the duct.
