Beschreibung
Zusammenfassung:	Inventia se refera la un fir poliesteric polifilamentar, netorsionat din polietilentereftalat, destinat a fi prelucrat prin tricotare si tesere, caracterizat prin aceea ca are finetea de 50...100 dtex. 16,20,24,32 filamente, tenacitatea minim 4,2 g/dtex. un numar de împâslituri de 18...50/m, alungire relativa la rupere de 10...24% si se obtine prin filarea unei topituri din granule de polietilentereftalat precristalizate la un grad de cristalinitate de minim 25%, uscate pâna la maxim 80 ppm umiditate, topitura fiind mai întâi filtrata, iar filamentele formate sunt evitate, antistatizate, etirate si trecute printr-un dispozitiv prin care se insufla aer cu presiunea de 3...4,5 at si temperatura de 18...30 degree C.
