Inqubo ye-Sublimation
I-Sublimation iyinqubo yamakhemikhali. Ngamagama alula (r), yilapho okuqinile kuphenduka igesi, ngokushesha, ngaphandle kokudlula esigabeni soketshezi esiphakathi. Lapho ubuza ukuthi kuyini ukuphrinta kwe-sublimation, kuyasiza ukuqaphela ukuthi kubhekise kudayi uqobo. Lokhu futhi sikubiza ngokuthi-i-sublimation, njengoba kungudayi oshintsha isimo.
I-Sublimation Print ngokuvamile isho ukuphrinta kwe-sublimation, okungukuthi, ukuphrinta kwe-Thermal sublimation.
1. Ubuchwephesha bokuphrinta bokudlulisa obudlulisela iphethini yombala kwiphethini endizeni yezingubo noma ezinye i-receptors ngokusebenzisa izinga lokushisa eliphezulu.
2. Imingcele eyisisekelo: Ukuphrinta kwe-Sublimation ubuchwepheshe bokuphrinta bokudlulisa, okubhekisela ekuphrinteni ama-pigments noma amadayi ephepheni, irabha noma ezinye izithwali. Ngokwezidingo ezingenhla, iphepha lokudlulisa kufanele lihlangabezane nala mazinga alandelayo:
(1) I-Hygroscopicity 40--100g/㎡
(2) Amandla okudabula acishe abe ngu-100kg/5x20cm
(3) Ukungena komoya okungu-500---2000l/min
(4) Isisindo 60--70g/㎡
(5) ph inani 4.5--5.5
(6) Ukungcola akukho
(7) Iphepha lokudlulisa kungcono lenziwe nge-softwood pulp. Phakathi kwazo, i-pulp yamakhemikhali kanye ne-pulp yemishini ngayinye ingcono. Lokhu kungaqinisekisa ukuthi iphepha le-decal ngeke libe brittle futhi libephuzi uma liphathwa ngezinga lokushisa eliphezulu.
Dlulisa Ukuphrinta
Okungukuthi, ukuphrinta kokudlulisa.
1. Enye yezindlela zokunyathelisa zezindwangu. Yaqala ngasekupheleni kwawo-1960. Indlela yokunyathelisa lapho idayi ethile iqala ukunyatheliswa kwezinye izinto ezifana nephepha, bese iphethini idluliselwa kwendwangu ngokucindezela okushisayo nezinye izindlela. Isetshenziswa kakhulu ukuphrinta i-chemical fiber knitwear nezingubo. Ukuphrinta kokudlulisa kuhamba ngezinqubo ezifana ne-sublimation kadayi, ukufuduka, ukuncibilika, nokuxebuka kongqimba lukayinki.
2. Amapharamitha ayisisekelo:
Odayi abafanele ukuphrinta ukudluliswa kufanele bahlangabezane nemibandela elandelayo:
(1) Odayi bokuphrinta ukudluliswa kufanele bancishiswe ngokuphelele futhi bangagxili emicu engaphansi kuka-210 °C, futhi bangathola ukushesha kokuwasha nokushesha koku-ayina.
(2) Odayi bokuphrinta bokudlulisa bangakwazi ukuncibilika ngokuphelele futhi baguqulwe babe ama-macromolecule kadayi wesigaba segesi ngemva kokushiswa, ukujiya ebusweni bendwangu, futhi bangasakazeka ku-fiber.
(3) Udayi osetshenziselwa ukuphrinta ukudlulisa unokuhambisana okuncane kwephepha lokudlulisa kanye nokuhambisana okukhulu kwendwangu.
(4) Udayi wokuphrinta wokudlulisa kufanele ube nombala ogqamile nogqamile.
Iphepha lokudlulisa elisetshenzisiwe kufanele libe nezici ezilandelayo:
(1) Kumelwe kube namandla anele.
(2) Ukuhambisana koyinki wombala kuncane, kodwa iphepha lokudlulisa kufanele libe nokuhlanganisa kahle kukayinki.
(3) Iphepha lokudlulisa akufanele likhubazeke, libe brittle futhi libephuzi ngesikhathi sokunyathelisa.
(4) Iphepha lokudlulisa kufanele libe ne-hygroscopicity efanele. Uma i-hygroscopicity impofu kakhulu, izobangela ukuthi uyinki wombala udlulele; uma i-hygroscopicity inkulu kakhulu, izobangela ukuguqulwa kwephepha lokudlulisa. Ngakho-ke, i-filler kufanele ilawulwe ngokuqinile lapho ikhiqiza iphepha lokudlulisa. Kufaneleka kakhulu ukusebenzisa i-semi-filler embonini yamaphepha.
I-Sublimation vs Ukudlulisa Ukushisa
- Siyawubona umehluko phakathi kwe-DTF ne-Sublimation.
- I-DTF isebenzisa ifilimu ye-PET njengendawo esetshenziswayo, kuyilapho i-Sublimation isebenzisa iphepha njengendawo esetshenziswayo.
I-2.Print Runs - Zombili izindlela zifaneleka kahle emibhalweni emincane yokuphrinta, futhi ngenxa yezindleko zokuqala ze-dayi-sub, uma uzophrinta isikibha esisodwa njalo ezinyangeni ezimbalwa, ungathola ukudluliswa kokushisa kangcono kuwe.
3.Futhi i-DTF ingasebenzisa uyinki omhlophe, kanti i-Sublimation ayisebenzisi.
4. Umehluko omkhulu phakathi kokudluliswa kokushisa kanye ne-sublimation ukuthi nge-sublimation, uyinki kuphela odlulisela kokubalulekile. Ngenqubo yokudlulisa ukushisa, ngokuvamile kunesendlalelo sokudlulisa esizodluliselwa ezintweni ezibonakalayo futhi.
5.Ukudluliswa kwe-DTF kungafinyelela izithombe zekhwalithi yesithombe futhi kuphakeme kune-sublimation. Ikhwalithi yesithombe izoba ngcono futhi icace ngokwengeziwe ngokuqukethwe okuphezulu kwe-polyester kwendwangu. Ku-DTF, umklamo osendwangu uzwakala uthambile uma uthintwa.
6. Futhi i-Sublimation ayisebenzi endwangu kakotini, kodwa i-DTF itholakala cishe kuzo zonke izinhlobo zendwangu.
I-Direct to Garment (DTG) vs i-Sublimation
- I-Print Runs - I-DTG iphinde ifanele ukugijima kokuphrinta okuncane, okufana nokuphrinta kwe-sublimation. Uzothola nokho ukuthi indawo yokuphrinta idinga ukuba ncane kakhulu. Ungasebenzisa udayi-sub ukuze umboze ngokuphelele ingubo ngokuphrinta, kuyilapho i-DTG ikukhawulela. Uhhafu wemitha yesikwele kungaba ukusunduza, kuyancomeka ukuthi unamathele ku-11.8″ kuya ku-15.7″.
- Imininingwane - Nge-DTG uyinki uyahlakaza, ngakho ihluzo nezithombe ezinemininingwane zizovela zenziwe ngamaphikiseli amaningi kunalokho okwenzeka esikrinini sekhompyutha yakho. Ukuphrinta kwe-sublimation kuzonikeza imininingwane ebukhali neyinkimbinkimbi.
- Imibala - Ukufiphala, ukukhanya nama-gradient akukwazi ukukhiqizwa kabusha ngokuphrinta kwe-DTG, ikakhulukazi engutsheni enemibala. Futhi ngenxa yama-palettes ombala asetshenziswe imifino ekhanyayo namapinki, nemibala yensimbi ingaba yinkinga. Ukuphrinta kwe-sublimation kushiya izindawo ezimhlophe zingaphrintiwe, kuyilapho i-DTG isebenzisa oyinki abamhlophe, abawusizo uma ungafuni ukuphrinta ezintweni ezimhlophe.
- Ubude Obude - I-DTG isebenzisa uyinki ngokuqondile engutsheni, kuyilapho ngokuphrinta kwe-sublimation uyinki uba yingxenye yengubo unomphela. Lokhu kusho ukuthi ngokuphrinta kwe-DTG ungathola ukuthi umklamo wakho uzoguga, uqhekeke, ucwebe, noma ukhuhle ngokuhamba kwesikhathi.
