Well this is news! Very many basic words in the Romanian language are of Greek origin, so your first statement doesn't really add up. But that's probably a different thread.ă is pronounced like e from English article the.
There are very few words in Romanian which have Greek origin. There are much more in Aromanian, for example...
However, most of the Romanian words related with classic fabric manufacturing are of Latin origin (aţă = line, iţă = shaft, lână = wool, pânză = cloth, fir = stitch etc.) (non-neologisms, of course). Some of the newest materials are of other origins (especially Turkic) but I can't figure out any of Greek origin, as far as I know.
