Abstract
Inventia se refera la un procedeu pentru obtinerea fibrelor poliamidice termostabile, utilizate, în special, pentru realizarea de fire cu destinatii tehnice, caracterizat prin aceea ca, în scopul asigurarii unei bune proprietati de stabilitate la actiunea agentilor oxidanti si a aerului în conditii de temperaturi ridicate, în prima faza se obtin granule pudrate cu o cantitate mare de amestec termostabilizant, iar apoi acestea sunt topite si introduse în polimer, proportia de componenti în polimerul filat-exprimat în greutate fata de polimer-fiind de 0,0103...0,0187% acetat cupric ca agent de cuplare, 0,0294...0,0129% clorura de sodiu sau clorura de potasiu sau iodura de potasiu ca agent de disproportionare, 0,0025...0,01% epsilon-caprolactama ca agent de complexare si 0,1...0,02% stearat de butil ca agent de plastifiere.
