Izingubo zemidlalo zibhekene nezinselele zokuqina okumanzi ngenxa yomswakama ophezulu kanye nokuchayeka kokujuluka. Lokhu kungasheshisa ukufuduka kodayi kanye nokudluliselwa kombala. Ukuqina kokuhlikihla okumanzi kuvame ukuba phansi ngoba amanzi athambisa udayi, okwenza kube lula ukuthi izinhlayiya zihlukane. Ukusetshenziswa kwezithako zokulungisa udayi kanye nezinto zokwenza ngemva kokwelashwa kungathuthukisa kakhulu izakhiwo zokuqina, ikakhulukazi ukotini kanye nezingxube. Lokhu kubhekana nalezi zinkinga ezingutsheni zezemidlalo.

Izilungisi zodayi ezithuthukisiwe, njenge-Disperse Dyes Fixer RG-E906, zenzelwe ukwakha izibopho eziqinile nama-molecule edayi endwangu. Le nqubo ivala umbala ngempumelelo. Iholela ekuthuthukisweni okukhulu kokuqina kwendwangu okumanzi. Lokhu kufaka phakathi ukuqina kwendwangu okuthuthukisiwe, ukuqinisekisa ukuthi izindwangu zigcina umbala wazo wokuqala ngemva kokugeza kaningi. Iphinde ithuthukise ukuqina kokujuluka, ivimbele ukuphuma kombala lapho ivezwa ukujuluka. Lokhu kubaluleke kakhulu ekugqokeni okusebenzayo.

Izinqubo Zokuhlanza Eziphumelelayo

Izinqubo zokuhlanza eziphumelelayo zibalulekile ekususeni amadayi angagxili ezimpahleni zemidlalo ezidaywe ngendlela eguquguqukayo. Lokhu kuvimbela ukopha kombala futhi kuqinisekisa ukuthi umbala awushiyi.

1. Ukuhlanza Kokuqala (Isigaba Sokuxubha): Qala ngokugeza ngamanzi abandayo, kulandelwe ukugeza ngamanzi ashisayo (40-50°C) imizuzu eyi-10. Lesi sigaba sihlose ukususa usawoti, ama-alkali, kanye nodayi abangagxilile ebusweni befayibha, ukulungiselela ukuhlikihla ngensipho okuphumelelayo.
2. Ukungathathi hlangothi (Ongakukhetha): Uma amadayi engakwazi ukumelana ne-alkali kahle, awasuse ebhavini le-acetic acid ngaphambi kokuwafaka ngensipho ukuze avimbele i-hydrolysis futhi agweme ukushintsha kombala (isb., amadayi abomvu aphenduka abe phuzi).
3. Inqubo Yokwenza Insipho: Lesi sinyathelo sikhuthaza ukusabalala kwamadayi angakaqiniwe afakwe i-hydrolyzed kusuka ngaphakathi kwefayibha kuya phezulu kanye nesisombululo sokuwasha. Ukushisa okwandayo kuthuthukisa ukusabalala futhi kunciphisa ukunamathelana kwedayi, kwandisa ukumuncwa. Gwema izihlanzi zensipho ezivamile kanye nama-surfactant angewona ama-ionic njengoba engasheshi ukusabalala. Izithasiselo ze-cationic zingathuthukisa ukuhlanza kodwa zingabangela ukuqiniswa kabusha. Izithasiselo ezikhethekile ezine-affinity ephezulu yedayi zingakha ama-complexes ukuvimbela ukumuncwa kabusha futhi kuthuthukise ukushesha kokwelashwa okumanzi.
4. Ukugeza Amanzi Ashisayo Ngemva Kokuhlanzwa: Geza ngamanzi ashisayo ku-70°C isikhathi esingaphezu kwemizuzu eyi-10 ukuze unciphise futhi ususe isixazululo sedayi esisele.
5. Ukugeza Amanzi Abandayo Kokugcina: Phetha ngokugeza ngamanzi abandayo.

Umgomo ojwayelekile ukuletha i-pH yendwangu eduze ne-neutral. Qinisekisa ukuthi ama-electrolyte esixazululweni sensipho awadluli ku-2g/L, njengoba lokhu kunciphisa ukusabalala kodayi okwenziwa nge-hydrolyzed kanye nokuqina kokuwasha. I-alkali esele ingathinta ukukhanya kombala lapho yoma.

Ukuze uthole indlela ewusizo kakhudlwana, cabanga ngalezi zinyathelo:

1. Ukuhlanza Amanzi Abandayo (Kuboshwe Indwangu): Gcina indwangu iboshiwe bese ugeza ngamanzi abandayo agelezayo kuze kube yilapho amanzi eqala ukuphuma kahle. Lokhu kusiza ukuvimbela ukufuduka kombala kanye nokungcola, ikakhulukazi ezindaweni ezimhlophe, futhi kususe i-soda ash alkali.
2. Amanzi Afudumele Hlanza Futhi Uhlanganise: Khulisa izinga lokushisa lamanzi ukuze lifudumale bese ukhulula indwangu ngenkathi uhlanza.
3. Ukugeza ngamanzi ashisayo nge-detergent: Geza ngamanzi ashisayo usebenzisa insipho yokuwasha izitsha noma yokuwasha. Imiyalelo yokuqala ye-Procion MX isikisela ukuthi ugeze emazingeni okushisa aseduze nokubila ngangokunokwenzeka, kodwa izincomo ezisebenzayo zeluleka ukuthi usebenzise amanzi ashisayo kakhulu okhululekile ngawo. Lesi sinyathelo sisiza ukususa udayi okhululekile, ongaqinile.
4. Ukuhlanza Amanzi Abandayo: Hlanza ngamanzi abandayo ngemva kokugeza okushisayo.
5. Phinda uma kudingeka: Phinda umjikelezo wokuwasha uma kudingeka kuze kube yilapho kungasaphumi dayi futhi imijikelezo yokuwasha/yokuhlanza isicacile.

Ukushisa Kokugcina Kokuzinza Kwedayi

Ukushisa kokugcina kunegalelo elikhulu ekuhlanzweni nasekuqineni kwezingubo zemidlalo ezenziwe ngodayi. Umshini wokucindezela ukushisa udlala indima ebalulekile enkambisweni yokuphrinta i-sublimation. Iqinisekisa ukuthi i-inki ye-sublimation ingena emicu yento. Lokhu kuphumela ekuphrinteni okungabonakali nje kuphela kodwa futhi okuhlala isikhathi eside kakhulu. I-inki iba yingxenye ye-substrate ngokwayo. Ngokungafani nezindlela zendabuko lapho i-inki ihlala khona ebusweni bento, i-sublimation ifaka umklamo ngaphakathi kwemicu, ikhulisa ukuqina kanye nokukhanga okubonakalayo.

Le nqubo ihilela izinyathelo eziningana ezibalulekile:

1. Ukusabalala Kwedayi: Uyinki we-sublimation uqukethe amadayi ahlakazekile. 380–400°F (193–204°C) ukushisa, lawa madayi aguquka kusuka ekubeni yinto eqinile abe yigesi.
2. Ukuvulwa kwe-Polymer: Emazingeni okushisa aphezulu, izintambo ze-polymer ze-polyester ziyakhululeka. Lokhu kuvumela ama-molecule edayi angena ku-fiber.
3. Ukupholisa Nokukhiya: Njengoba indwangu iphola, amaketanga e-polymer ayavaleka, evala ama-molecule edayi ngaphakathi kwesakhiwo. Umphumela uba yisibopho esihlala njalo esimelana nokugezwa, ukuguguleka, kanye nokuvezwa yi-UV.

Izinhlobo ezahlukene zezindwangu zidinga izimo ezithile zokubeka ukushisa ukuze kufezwe ukugcinwa kombala okuhle kakhulu:

Uhlobo Lwendwangu	Izinga lokushisa (°F)	Isikhathi Sokuhlala (Amasekhondi)	Izinga Lokucindezela	Ukugcinwa Kombala Ngemva Kokuwasha (%)
I-Polyester engu-100%	380–400	45–60	Okuphakathi (≈40 psi)	90–95%
65/35 Ukotini Ohlanganisiwe	375–385	50–60	Okuphakathi (≈40 psi)	70–75%
50/50 Ukotini Ohlanganisiwe	370–380	60–70	Okuphakathi-Okuphezulu (≈50 psi)	50–55%
Ukotini ongu-100% + Ukugqoka	360–375	60–75	Okuphakathi-Okuphezulu (≈50 psi)	65–70%

Isibonelo, amashethi e-polyester ashiswa ngokushisa ku-390°F imizuzwana engama-50 agcina cishe u-90% wokucaca kanye nokudlidliza ngemva kokuwashwa izikhathi ezingama-25. Amashethi ekotini angalungiswanga, esebenzisa izilungiselelo ezifanayo, afinyelele kuphela ubuningi bombala obungaba ngu-30% kanye nokufiphala okukhulu ngemva kokuwashwa izikhathi eziyi-10 kuphela. Ukotini one-poly coating uthuthuke waba ngu-65–70% wokugcina, kodwa lokhu kwengeze cishe u-20% wezindleko ezengeziwe ngeyunithi ngayinye.
