Muri mortila yumye, cellulose ether ni inyongeramusaruro ikomeye ishobora kunoza cyane imikorere ya mortila yumye kandi ikagira ingaruka ku mikorere y’ubwubatsi bwa mortila. Methyl cellulose ether igira uruhare mu kubika amazi, gukuba, no kunoza imikorere y’ubwubatsi. Imikorere myiza yo kubika amazi ituma mortila itazatera gusya, gusya ifu no kugabanya imbaraga bitewe n’ibura ry’amazi n’amazi make ya sima; ingaruka zo gukuba Imbaraga z’imiterere ya mortila yumye ziyongera cyane, kandi kongeramo methyl cellulose ether bishobora kunoza cyane ubukana bw’urukuta rutose, kandi bikagira isano nziza n’ibintu bitandukanye, bityo bikanoza imikorere ya mortila yumye ku rukuta no kugabanya imyanda; byongeye kandi, bitandukanye Uruhare rwa cellulose mu bicuruzwa narwo ruratandukanye, urugero: cellulose mu matiles ashobora kongera igihe cyo gufungura no guhindura igihe; cellulose mu mortila ikoreshwa mu buryo bwa mashini ishobora kunoza imbaraga z’imiterere ya mortila yumye; mu kwihuza, cellulose igira uruhare mu gukumira gutuza, gutandukanya no gushyira mu byiciro.
Umusaruro wa eteri ya selulose ukorwa ahanini n'imigozi karemano binyuze mu gushonga kwa alkali, gukora interfying reaction (etherification), gukaraba, kumisha, gusya n'izindi nzira. Ibikoresho by'ingenzi by'imigozi karemano bishobora kugabanywamo: fibre y'ipamba, fibre ya sederi, fibre ya beech, nibindi. Ubunini bwa polymerization bwabyo buratandukanye, bizagira ingaruka ku bucucike bwa nyuma bw'ibicuruzwa byabo. Kuri ubu, abakora cellulose bakomeye bakoresha fibre y'ipamba (ibikomoka kuri nitrocellulose) nk'ibikoresho by'ibanze. Eteri za selulose zishobora kugabanywamo ionic na non-ionic. Ubwoko bwa ionic bugizwe ahanini n'umunyu wa carboxymethyl cellulose, naho ubwoko butari ionic bugizwe ahanini na methyl cellulose, methyl hydroxyethyl (propyl) cellulose, na hydroxyethyl cellulose. Su n'ibindi. Mu ifu yumye, kubera ko cellulose ya ionic (umunyu wa carboxymethyl cellulose) idahindagurika iyo hari iyoni za kalisiyumu, ntabwo ikoreshwa gake mu bicuruzwa by'ifu yumye nka sima yasinzwe nk'ibikoresho bya sima.
Uburyo amazi abikwamo muri selulosi nabwo bufitanye isano n'ubushyuhe bukoreshwa. Uburyo amazi abikwamo muri eteri ya methyl cellulose bugabanuka uko ubushyuhe bwiyongera. Urugero, mu mpeshyi, iyo hari izuba ryinshi, putty yo hanze irashyirwamo plaster, akenshi yihutisha ubushyuhe bwa sima na sima. Gukomera no kugabanuka k'umuvuduko wo kubikamo amazi bitera kumva ko imikorere y'ubwubatsi ndetse n'imikorere yo kurwanya gucikamo ibice bizagira ingaruka. Muri iki gihe, ni ngombwa cyane kugabanya ingaruka z'ubushyuhe. Hari igihe idashobora guhaza ibyifuzo by'ikoreshwa. Uburyo bumwe bwo kuvura bukorerwa kuri selulosi, nko kongera urugero rwa etherification, nibindi, kugira ngo ingaruka zo kubikamo amazi zikomeze kugira ingaruka nziza ku bushyuhe buri hejuru.
Kubika amazi muri selulosi: Ibintu by'ingenzi bigira ingaruka ku kubika amazi muri selulosi birimo ingano ya selulosi yongewemo, ubukana bwa selulosi, ubuto bwa selulosi, n'ubushyuhe bw'aho ikora.
Ubwinshi bwa selulose: Muri rusange, uko ubunini bw'amazi burushaho kwiyongera, ni ko ingaruka nziza zo kubika amazi, ariko uko ubunini bw'amazi burushaho kwiyongera, ni ko uburemere bwa selulose burushaho kwiyongera, ndetse no kugabanuka k'ubushonge bwayo, bigira ingaruka mbi ku mikorere y'ubwubatsi n'imbaraga za selulose. Uko ubunini bw'amazi burushaho kwiyongera, ni ko ingaruka zo gukomera ku selulose zigaragara cyane, ariko ntabwo bingana neza. Uko ubunini bw'amazi burushaho kwiyongera, ni ko selulose itose izaba ikomeye cyane. Mu gihe cyo kubaka, izafata ku gikoresho cyo gukurura kandi ifatanye cyane n'icyapa, ariko ntacyo bizafasha cyane mu kongera imbaraga z'imiterere ya selulose itose ubwayo, kandi imikorere yo kurwanya gushonga ntizagaragara mu gihe cyo kubaka.
Ubunini bwa selulosi: Ubunini bugira ingaruka ku gushonga kwa eteri ya selulosi. Selulosi isanzwe iba ifite utubumbe duto kandi yoroshye gukwirakwira mu mazi nta guhurirana, ariko igipimo cyo gushonga kiba gito cyane. Ntibikwiriye gukoreshwa mu gikoresho cy'ifu yumye. Bikorerwa mu rugo. Imwe muri selulosi irashyuha, ntabwo byoroshye gukwirakwira no gushonga mu mazi, kandi biroroshye guterana. Ifu nziza ihagije ni yo yonyine ishobora kwirinda guterana kwa eteri ya methyl cellulose iyo wongeyeho amazi kandi uvangavanga. Ariko eteri ya selulosi ikomeye ntabwo iba isesagura gusa ahubwo inagabanya imbaraga za selulosi. Iyo selulosi nk'iyo y'ifu yumye ikozwe ahantu hanini, umuvuduko wo guterana kwa selulosi yo mu gace uragabanutse, kandi imyanya igaragara bitewe n'ibihe bitandukanye byo guterana. Kubera igihe gito cyo kuvanga, selulosi ifite imiterere isaba ubunini bwinshi.
