Ether ea seluloseke lentsoe le kopaneng bakeng sa mefuta e fapaneng ea lintho tse tsoang ho cellulose ea tlhaho (k'hothone e hloekisitsoeng le pulp ea lehong, jj.) ka ho etherification. Ke sehlahisoa se entsoeng ka ho nkeloa sebaka ha lihlopha tsa hydroxyl ka karolo e itseng kapa ka botlalo ka har'a li-macromolecule tsa cellulose ke lihlopha tsa ether, 'me ke derivative e tlase ea cellulose. Kamora ho etherification, cellulose e qhibiliha ka metsing, e qhibilihisa litharollo tsa alkali, le li-solvents tsa organic, 'me e na le thepa ea thermoplastic. Ho na le mefuta e mengata ea li-ether tsa cellulose, tse sebelisoang haholo liindastering tse kang kaho, samente, liphahlo, meriana, lijo, peterole, lik'hemik'hale tsa letsatsi le letsatsi, masela, ho etsa pampiri le likarolo tsa elektroniki. Ho ea ka palo ea lintho tse nkeloang sebaka, e ka aroloa ka li-ether tse le 'ngoe le li-ether tse tsoakiloeng, 'me ho ea ka ionization, e ka aroloa ka li-ether tsa cellulose tsa ionic le li-ether tsa cellulose tse seng tsa ionic. Hona joale, ts'ebetso ea tlhahiso ea lihlahisoa tsa ionic tsa ionic tsa cellulose tsa ionic e se e butsoitse, e bonolo ho e hlahisa, 'me litšenyehelo li tlase haholo. Thibelo ea indasteri e tlase haholo, 'me e sebelisoa haholo-holo masimong a li-additives tsa lijo, li-additives tsa masela, indasteri ea lik'hemik'hale ea letsatsi le letsatsi, jj. Ke sehlahisoa se seholo se hlahisoang 'marakeng.
Hona jwale, sehlopha se sehololi-ether tsa seluloseLefatšeng ke CMC, HPMC, MC, HEC, jj. Har'a tsona, CMC e na le tlhahiso e kholo ka ho fetisisa, e etsang hoo e ka bang halofo ea tlhahiso ea lefats'e, ha HPMC le MC li etsa hoo e ka bang 33% ea tlhoko ea lefats'e, 'me HEC e etsa hoo e ka bang 13% ea 'maraka oa lefats'e. Tšebeliso ea bohlokoa ka ho fetisisa ea Carboxymethyl cellulose (CMC) ke sesepa, se etsang 22% ea tlhoko ea 'maraka o theohelang. Lihlahisoa tse ling li sebelisoa haholo-holo lisebelisoa tsa kaho, lijo le meriana.
