Abstract

Procedeu pentru obtinerea unor corpuri tubulare plastifiate, pe baza de derivati ai celulozei, utilizate, în special, ca învelis sintetic pentru cîrnati, prin injectarea solutiei de celuloza printr-o duza de formare într-un lichid de coagulare, dupa care corpul tubular format se trece prin bai de regenerare si spalare, se trateaza cu o solutie apoasa acida a unui plastifiant secundar ca: glicerina, glicol, poliglicol si, în final, se usuca sub actiunea caldurii si apoi se umezeste cu apa.
