Abstract
Inventia se refera la un fir poliesteric multifilamentar, cu finete si torsiune mari, constituit din polietilentereftalat, matisat cu 1,8..2,2% dioxid de titan, avand viscozitate specifica de 0,75..0,8 densitatea de lungimea a acestuia de 50..110 dtex, 16..32 filamente, tenacitatea de minimum 3,0 gf/drex, alungirea la rupere 23..46%, constructia termica de 200 grade C de 4..11%, 700-2800 torsiuni/m, uniformitatea de vopsire de min 90%, care se obtine prin filarea tipuri de granule de polietilentereftalat matiste cu o vîscozitate specifica de 0,78..0,83, precristalizate si uscate cu aer cu punct de roua de minim -30grade C, la 170..220grade C, topite într-un extruder la 288..310 grade C, jeturile formate fiind într-un extruder la 288..310grade C, jeturile formate fiind solidificate într-un canal de racire, prin insuflarea cu aer la viteza de 0,4..0,8 m/s temperatura de 22+- 2 grade C, umiditate relativa 55..70% filamentele rezultate, tratate cu emulsie de avivare si antistatizare si fixate.
