摘要

The present invention is directed to a method and a system for the production of at least one polymeric yarn comprising means for mixing a polymer (1) with a first solvent yielding a mixture; means for homogenizing the mixture; means for rendering the mixture inert (21, 22, 23); means for dipping the mixture into a quenching bath (30), wherein an air gap is maintained before the mixture reaches the quenching bath (30) liquid surface forming at least one polymeric yarn; means for drawing (41) the at least one polymeric yarn at least once; means for washing (5) the at least one polymeric yarn with a second solvent that is more volatile than the first solvent; means for heating the at least one polymeric yarn (6); means for drawing at room temperature (7) the at least one polymeric yarn at least once; and means for heat drawing (8) the at least one polymeric yarn at least once.;The instant invention also concerns a system and method of dosing a polymer mixture with a first solvent into an extruder (26), a device (5), a system and a method of solvent extraction from at least one polymeric yarn, and a method and system of mechanical pre-recovery (4) of at least one liquid in at least one polymeric yarn.
