1. Gusukura bwa mbere (Intambwe yo gushonga): Tangira woza amazi akonje, hanyuma woza amazi ashyushye (40-50°C) mu gihe cy'iminota 10. Iki cyiciro kigamije gukuraho umunyu, alkali, n'irangi ridafite ifu ku buso bwa fibre, witegure gukoresha isabune neza kurushaho.
2. Kutagira aho bibogamiye (Ntabwo ari ngombwa): Niba irangi ridafite ubushobozi bwo kurwanya alkali, rishyire mu mwobo wa aside asetiki mbere yo kurisiga isabune kugira ngo hirindwe ko rihinduka hydrolysis kandi hirindwe impinduka z'ibara (urugero: irangi ritukura rihinduka umuhondo).
3. Uburyo bwo gusiga isabune: Iyi ntambwe ituma amarangi adafunze neza ava imbere muri fibre ajya hejuru no mu gikoresho cyo kumesa. Ubushyuhe bwiyongera butuma amarangi akwirakwira kandi bugagabanya uburyo akwirakwira mu irangi, bigatuma ritagenda neza. Irinde koza isabune isanzwe n'ibinyabutabire bitari ionic kuko bitihutisha uburyo akwirakwira mu irangi. Inyongera za cationic zishobora kunoza isuku ariko zishobora gutuma ritagenda neza. Ibikoresho byihariye bifite uburyo bwinshi bwo gukwirakwira mu irangi bishobora gukora ibintu bitandukanye kugira ngo bitazongera gukwirakwira mu irangi no kunoza uburyo bwo kuvura amazi vuba.
4. Gukaraba amazi ashyushye nyuma yo gukaraba: Karaba amazi ashyushye kuri dogere selisiyusi 70 mu gihe kitarenze iminota 10 kugira ngo wongere uvanemo irangi risigaye.
5. Gukaraba amazi akonje bya nyuma: Soza ukoresheje amazi akonje yo gukaraba.

Intego rusange ni ukugeranya pH y'imyenda hafi ya neutral. Menya neza ko electrolytes ziri mu gikoresho cyo gusukamo isabune zitarenga 2g/L, kuko bigabanya ikwirakwira ry'irangi rya hydrolyzed no kwihuta mu gukaraba. Alkali isigaye ishobora kugira ingaruka ku rumuri rw'amabara iyo yumye.

Kugira ngo habeho uburyo bufatika kurushaho, tekereza kuri izi ntambwe:

1. Koza amazi akonje (Uhambiriye imyenda): Komeza uhambire umwenda hanyuma woge n'amazi akonje atemba kugeza igihe amazi atangiye gushonga. Ibi bifasha kwirinda kwimuka kw'amabara no kwangirika kw'amabara, cyane cyane ahantu hera, kandi bigakuraho alkali y'ivu rya soda.
2. Amazi ashyushye Sukura hanyuma uhuze: Ongera ubushyuhe bw'amazi kugira ngo ashyushye kandi ufungure umwenda mu gihe woza.
3. Koza amazi ashyushye ukoresheje isabune: Karaba mu mazi ashyushye ukoresheje isabune yo koza amasahani cyangwa isabune yo kumesa imyenda. Amabwiriza ya mbere ya Procion MX atanga inama yo koza ku bushyuhe buri hafi kubira uko bishoboka kose, ariko inama zingirakamaro zikugira inama yo gukoresha amazi ashyushye cyane wishimiye. Iyi ntambwe ifasha gukuraho irangi ridafite ishingiro.
4. Koza amazi akonje: Oza n'amazi akonje nyuma yo gukaraba bishyushye.
5. Subiramo niba ari ngombwa: Subiramo ukore imyitozo yo gukaraba niba bikenewe kugeza igihe nta rindi rangi rivuyeho kandi igihe cyo gukaraba/gukaraba kimaze kuba cyiza.

Uburyo bwa nyuma bwo gushyushya kugira ngo irangi ritagorana

Gushyira ubushyuhe bwa nyuma bigira uruhare runini mu koza no kwihutisha imyenda ya siporo ya siporo irangi. Imashini ishyushya ifite uruhare runini mu gikorwa cyo gucapa sublimation. Bituma wino ya sublimation yinjira mu migozi y'ibikoresho. Ibi bituma habaho amashusho adahinduka gusa ahubwo aramba cyane. Wino iba igice cy'umugozi ubwawo. Bitandukanye n'uburyo gakondo aho wino iba iri ku buso bw'ibikoresho, sublimation ishyira igishushanyo mu migozi, yongera uburambe n'ubwiza bw'amaso.

Iyi gahunda ikubiyemo intambwe nyinshi z'ingenzi:

1. Gukwirakwiza irangi: Inki zo mu bwoko bwa Sublimation zirimo amarangi atatanye. Munsi Ubushyuhe 380–400°F (193–204°C) ubushyuhe, aya marangi ahinduka kuva ku kintu gikomeye kikajya kuri gaze.
2. Gufungura polimeri: Iyo ubushyuhe bwinshi bukabije, iminyururu ya polymer ya polyester irarekura. Ibi bituma molekile z'irangi ry'imyuka zinjira muri fibre.
3. Gukonjesha no Gufunga: Uko umwenda ukonje, iminyururu ya polymer irafunga, igafunga molekile z'irangi imbere mu nyubako. Ibi bivamo isano ihoraho idakaraba, iterwa no kwangirika, gushwanyagurika, no kwangirika n'imirasire y'izuba.

Ubwoko butandukanye bw'imyenda busaba imiterere yihariye yo gushyira ubushyuhe kugira ngo ibara rigumane neza:

Ubwoko bw'imyenda	Ubushyuhe (°F)	Igihe cyo gutura (amasegonda)	Urwego rw'umuvuduko	Gufata ibara nyuma yo gukaraba (%)
Polyester 100%	380–400	45–60	Hagati (≈40 psi)	90–95%
65/35 Poly-Cotton	375–385	50–60	Hagati (≈40 psi)	70–75%
50/50 Poly-Cotton	370–380	60–70	Hagati-Hejuru (≈50 psi)	50–55%
Ipamba 100% + Irangi	360–375	60–75	Hagati-Hejuru (≈50 psi)	65–70%

Urugero, amashati ya polyester yashyizwe mu bushyuhe kuri dogere 390 mu gihe cy'amasegonda 50 yagumanye ubushobozi bwo gukora neza no kumererwa neza ku kigero cya 90% nyuma yo kumesa inshuro 25. Amashati ya cotton atavuwe, hakoreshejwe uburyo bumwe, yageze ku bucucike bw'amabara bungana na 30% gusa, ahita ashira cyane nyuma yo kumesa inshuro 10 gusa. Ipamba ifite irangi rya poly yarushijeho kugumana ubushyuhe ku kigero cya 65–70%, ariko ibi byongereyeho hafi 20% by'ikiguzi cy'inyongera kuri buri gikoresho.
