Abstract

Inventia se refera la un procedeu ce include spalarea granulelor de polimer cu azot topirea si încalzirea dozarea topiturii si a fluidului de calibrare filarea si calibrarea si formarea firelor extirarea în doua trepte termofixarea racirea spalarea si bobinare. Se revendica si o instalatie de realizare a procedeului. Inventia se aplica în industria filarii fibrelor chimice textile.The invention relates to a process comprising washing the polymer granules with nitrogen melting and heating dosing the melt and calibrating fluid filaments and calibrating and forming the yarns extrusion in two steps thermal setting cooling cooling and winding. An installation for carrying out the process is also claimed. The invention is applied in the chemical fiber spinning industry.
