Abstract

Inventia se refera la un procedeu de obtinere a unui fir polifilamentar poliesteric constînd în filarea la temperaturi de 275 + - 3 degree C a unei topituri ce contine 5 100% materiale refolosibile de la faza de filare-etirare, plastcompactate cu o turatie a snecului de 1 719 RPM granulate, postpolicondensate într-un uscator rotativ, timp de 10-24 h, temperatura agentului de încalzire de 215-230 degree C, pîna la I.V.= 0,840 + - 0,2, topite în extruder cu temperaturile în cele 5 zone de 272-278 degree C, 282-288 degree C, 287-293 degree C, 282-288 degree C, 277-285 degree C, firele polifilamentare rezultate fiind etirate la un raport de etirare de 5,7-5,8 la temperatura galetilor de 97-103 degree C, 125-135 degree C, 220-230 degree C si apoi prelucrate în conditii în sine cunoscute.The invention relates to a process for obtaining a polyester polyfilament yarn consisting of a 275 + - 3 ° C coiling of a melt containing 5 100% of reusable materials from the spinning-etiquette phase, plastic-compacted with a speed of the sink 1 719 RPM granulates, post-polarized in a rotary dryer for 10-24 hours, heating agent temperature 215-230 ° C, up to IV = 0.840 ± 0.2, melted in extruder with temperatures in the 5 zones 272-278 degrees C, 282-288 degrees C, 287-293 degrees C, 282-288 degrees C, 277-285 degrees C, the resulting polyfilamentary threads being etched at an ejection ratio of 5.7-5.8 at bucket temperature 97-103 degrees C, 125-135 degrees C, 220-230 degrees C and then processed under conditions known per se.
