Ukukhishwa ukotini nezinye i-cellulosic fibers

I-scouring iyinqubo emanzi ebaluleke kakhulu esetshenziswa ezintweni zendwangu ngaphambi kokudaya noma ukuphrinta.Ikakhulukazi kuyinqubo yokuhlanza lapho kukhishwa khona izinto zangaphandle noma ukungcola.Inqubo yokuhlanza, ngenkathi ihlanza i-α-cellulose, idlulisela uhlamvu lwe-hydrophilic kanye nokungena okudingekile ezinkambisweni ezilandelayo (i-bleaching, i-mercerizing, ukudaya noma ukuphrinta).Ukukhuhla okuhle kuyisisekelo sokuqeda ngempumelelo.Ukusebenza kwenqubo yokukhuhla kwehlulelwa ngokuthuthuka kokumanzisa kwezinto ezikhuhliwe.

Ikakhulukazi, ukukhuhla kwenziwa ukuze kukhishwe amafutha angafuneki, amafutha, amawax, ukungcola okuncibilikayo nanoma yikuphi ukungcola okuyizinhlayiyana noma okuqinile okunamathela emiculweni, okungase kuphazamise inqubo yokudaya, ukuphrinta nokuqeda.Inqubo empeleni iqukethe ukwelashwa ngensipho noma okokuhlanza okune-alkali noma ngaphandle kokwengezwa.Ngokuya ngohlobo lwefayibha, i-alkali ingase ibe buthakathaka (isb. isoda ash) noma iqine (i-caustic soda).

Lapho kusetshenziswa insipho, amanzi athambile ayadingeka.I-ion yensimbi (Fe³⁺kanye noCa²⁺) ekhona emanzini aqinile futhi i-pectin kakotini ingakha insipho engancibiliki.Inkinga inzima kakhulu lapho ukukhuhla kwenziwa ngenqubo eqhubekayo ehilela ukugeza kwe-padding lapho isilinganiso sotshwala siphansi kakhulu kunenqubo ye-batch;i-chelating noma i-ejenti yokuthungatha, isb, i-Ethylenediaminetetraacetic acid (EDTA), i-Nitrilotriacetic acid (NTA), njll., ingasetshenziswa ukuvimbela ukwakheka kwe-scum kanye nefilimu.I-detergent yokwenziwa yekhwalithi ephezulu inikeza ibhalansi enhle ngokumanzisa, ukuhlanza, ukufaka i-emulsifying, ukuhlakazeka kanye nezakhiwo ezikhipha amagwebu, ngaleyo ndlela unikeze ikhono elihle lokuhlanza.Izihlanzi ze-anionic, ezingezona i-ionic noma imixube yazo, imixube yezihlanzi ezisiza ukuncibilika nezinsipho zisetshenziswa kakhulu ekukhunjweni.Ukuze kusheshiswe inqubo yokuhlanza, ngezinye izikhathi kusetshenziswa ama-ejenti okumanzisa ngokuhlanganyela nezincibilikisi eziphezulu zokubilisa (i-cyclohexanol, i-methylcyclohexanol, njll.) ngezinye izikhathi, kodwa inqubo ingase ingabi ne-eco-friendly.Umsebenzi wezincibilikisi ukuncibilikisa amafutha namawakisi angancibiliki.

Abakhi bayengezwa kubhavu obilisa i-kier ukwandisa umsebenzi wensipho noma okokuhlanza.Lawa ngokuvamile usawoti onjenge-borates, i-silicates, i-phosphates, i-sodium chloride noma i-sodium sulphate.I-sodium metasilicate (Na₂SiO₃, 5h₂O) ingasebenza futhi njengesihlanzi kanye nesigcinalwazi.Umsebenzi wesigcinalwazi ukushayela insipho isuka esigabeni samanzi iye endaweni yokubona indwangu/yamanzi futhi ngenxa yalokho kwandise ukugcwala kwensipho engutsheni.

Ngesikhathi ubiliswa ukotini nge-caustic soda, umoya ovalelwe ungase ubangele i-oxidation ye-cellulose.Lokhu kungase kuvinjwe ngokwengezwa kwe-ejenti yokunciphisa kancane efana ne-sodium bisulphite noma i-hydrosulphite otshwaleni bokukhuhla.

Izinqubo zokukhuhla zezinto ezihlukene zendwangu ziyahlukahluka kakhulu.Phakathi kwemicu yemvelo, ukotini oluhlaza utholakala ngendlela ehlanzekile kakhulu.Inani eliphelele lokungcola okufanele lisuswe lingaphansi kuka-10% wesisindo esiphelele.Noma kunjalo, ukubilisa isikhathi eside kuyadingeka njengoba ukotini uqukethe ama-wax anesisindo samangqamuzana aphezulu, okunzima ukuwasusa.Amaprotheni aphinde alale emgodini omaphakathi we-fiber (lumen) okungenakufinyeleleka kalula kukhemikhali esetshenziswa ukukhuhla.Ngenhlanhla i-cellulose ayithinteki ngokwelashwa isikhathi eside ngesisombululo se-caustic kuze kufike ekugxilweni kuka-2% lapho ungekho umoya.Ngakho-ke, kungenzeka ukuguqula konke ukungcola ngesikhathi sokukhuhla, ngaphandle kwezindaba zemvelo zombala, kube yifomu encibilikayo, engagezwa ngamanzi.

Ukukhipha imicu ye-cellulosic ngaphandle kukakotini kulula kakhulu.Imicu ye-bast efana ne-jute ne-fl ax ayikwazi ukuhluzwa ngokwehlukana ngenxa yamathuba okususwa kwezakhi ezimbalwa ezingenazo i-fibrous ngokulimala okuwumphumela kwento.Lezi zivame ukuhluzwa kusetshenziswa insipho noma okokuhlanza kanye nomlotha wesoda.I-Jute ivame ukusetshenziswa ngaphandle kokuhlanzwa okwengeziwe, kodwa i-fl ax ne-ramie kuvame ukuhluzwa futhi kuvame ukwenziwa mhlophe.I-Jute yokudaya i-scoured ngaphambili kodwa kusele amanani amaningi e-lignin, okuholela ekusheshiseni ukukhanya okungekuhle.

Njengoba ukungcola okungokwemvelo okufana ne-cotton wax, izinto ze-pectic kanye namaprotheni zihlotshaniswa ikakhulukazi ngaphakathi kodonga oluyinhloko, inqubo yokukhuhla ihlose ukususa lolu donga.
