Claims (13)
1. Postupak za regeneraciju celuloznih vlakana iz tekstila koji sadrži i celulozu i sintetička vlakna, naznačen time da obuhvaća korake:
(a) tretiranja tekstila celuloznim otapalom koji sadrži aminoksid da bi se otopi celuloza na temperaturi od 40-120 °C, u trajanju 1-90 minuta i s koncentracijom celuloze u tekućoj fazi koja sadrži celulozu od 0,5-35 wt.%,
(b) odvajanje tekućoj faze koja sadrži celulozu od sintetičkih vlakana, dekantiranjem, centrifugiranjem ili filtracijom; i
(c) odvajanje tekuće faze koja sadrži celulozu od sintetičkih vlakana celuloze da bi se proizvela vlakna celuloze,
gdje se tekstil obrađuje s biokatalitičkim ili kemijskim pojačivačem otapanja prije ili tijekom koraka otapanja (a) kako bi se stupanj polimerizacije celuloze u rasponu 200-1200 izmjerio prema ASTM D1795.
2. Postupak sukladno patentnom zahtjevu 1, naznačen time da tekstil sadrži pamuk kao celulozna vlakna.
3. Postupak prema patentnom zahtevu 2, naznačen time da sintetička vlakna sadrže polietilen tereftalat, polipropilen i/ili poliamid, poželjno polietilen tereftalat.
4. Postupak sukladno bilo kojem od prethodnih patentnih zahtjeva, naznačen time da se korak (a) provodi na temperaturi od 85-100 ° C.
5. Postupak sukladno bilo kojem od prethodnih patentnih zahtjeva, naznačen time da se korak (a) provodi tijekom 30-60 minuta.
6. Postupak sukladno patentnom zahtjevu 1, naznačen time da je pojačivač otapanja enzim, poželjno je celuloza.
7. Postupak sukladno patentnom zahtjevu 1, naznačen time da je pojačivač otapanja oksidacijsko sredstvo.
8. Postupak sukladno patentnom zahtjevu 1, naznačen time da je pojačivač otapanja kiselina.
9. Postupak sukladno bilo kojem od prethodnih patentnih zahtjeva, naznačen time da se u koraku (a) doda antioksidans, poželjno propilgalat.
10. Postupak sukladno bilo kojem od prethodnih patentnih zahtjeva, naznačen time da otapalo celuloze sadrži N-metil morfolin N-oksid.
11. Postupak sukladno patentnom zahtjevu 10, naznačen time da se N-metil morfolin N-oksid koristi za smjesu s vodom.
12. Postupak sukladno bilo kojem od prethodnih patentnih zahtjeva, naznačen time da je koncentracija celuloze u tekućoj fazi koja sadrži celulozu 10-17 wt.%.
13. Postupak sukladno bilo kojem od prethodnih patentnih zahtjeva, naznačen time da se u koraku (c) tekuća faza koja sadrži celulozu pumpa kroz mlaznice, nakon čega slijedi ispiranje i sušenje dobivenih vlakana.
