I. Incamake y'ikoranabuhanga ryo gucapa Sublimation
Gucapa sublimation ni ubwoko bushya bw'uburyo bwo gucapa bushingiye ku miterere ya sublimation y'amabara atatanye. Ihame nyamukuru ni ugucapa amabara atatanye kuva ku buryo bukomeye kugera ku buryo bushyushye binyuze mu bushyuhe bwinshi (180-230℃), yinjira mu nsinga za sintetike hanyuma agakomera. Kuva aho yatangiriye mu nganda mu myaka ya 1970, ubu buryo bwabaye uburyo bwiza bwo gucapa ku myenda ya polyester na polyester-spandex bitewe n'uko ibungabunga ibidukikije (nta gukaraba, nta gusohora amazi mabi) no kugaragaza imiterere yayo neza.
Uburyo bwo gukoresha imyenda ya polyester ni ikintu gikomeye cyane, kuko imiterere yayo ya molekile mu kwaguka kw'ubushyuhe bwinshi, kugira ngo byorohereze kwinjira kwa molekile z'irangi; kandi imyenda ya polyester-Spandex (polyester ivanze irimo spandex) igomba kwemeza ko ingano ya polyester itari munsi ya 70%, kugira ngo irangi ryinjire neza. Ugereranyije n'uburyo busanzwe bwo gucapa ecran, icapiro rya Sublimation rishobora gukora amasaha 72 adahinduka, umuvuduko ushobora kugera kuri 2000-3000 m / h, kandi imiterere ifite ubushobozi bukomeye bwo gushyira mu byiciro, ingaruka z'amabara zigera kuri 256.
II. Inzira n'ikoranabuhanga ry'ingenzi
1. Mbere yo kuvurwa no guhitamo ibikoresho
Imyenda iboshywe na Polyester-Spandex igomba gutekwa neza, igashushanywa neza kandi ingana kugira ngo ikemure ibibazo byo gusimbuka no gupfundika impande. Gukoresha imashini icapa ifite uburyo bwo kwinjira bishobora kunoza uburyo imyenda igenda neza kandi bigabanye ibara. Impapuro zo kwimura zikozwe mu Buholandi zifite ubushyuhe bwinshi kandi zisizwe na silicone layer kugira ngo zongere ubushobozi bwo kurekura irangi.
2. Gushushanya no gucapa hakoreshejwe ikoranabuhanga
Nyuma yo kurangiza igishushanyo mbonera binyuze muri porogaramu ya CAD, umutwe w’icapiro wa 720dpi x 720dpi ukoreshwa mu gucapa wino y’irangi ikwirakwizwa ku mpapuro zo kohereza. Hakwiye kwitabwaho igishushanyo mbonera cy’indorerwamo (horizontal flip) kugira ngo kijyane n’icyerekezo cyo kohereza gikurikiraho, mu gihe hagenzurwa ubukana bw’iwino buri hagati ya 3-10mPa-s kugira ngo hirindwe ko umutwe w’icapiro ufunga.
3. Uburyo bwo kohereza ubushyuhe mu gikoresho cyo gusohora
Ubushyuhe bwo kohereza ubusanzwe bushyirwa kuri 180-210°C, igitutu kigenzurwa kuri 10-12kPa, kandi igihe kigahindurwa kikagera ku masegonda 20-45 bitewe n'ubunini bw'imyenda. Ibikoresho bikoresha umwuka udafite igitutu (13.3kPa) bishobora kunoza cyane uburyo irangi ryinjiramo, cyane cyane ku myenda ya polyester-spandex ifite ubukana bwinshi kugira ngo hirindwe gukomera kw'intoki. Dufashe urugero rw'imyenda ya polyester-spandex, polyester nyinshi ishobora gukoreshwa hamwe n'ibipimo bya 180-210°C/30s, mu gihe imyenda ya siporo ifite ubukana bwinshi isaba igihe gito kugira ngo spandex idakwirakwira.
4. Gusoza no kugenzura ubuziranenge
Gushyira ubushyuhe bwinshi (150-180℃ / iminota 2) birakenewe nyuma yo kwimura kugira ngo hongerwe ubushyuhe bw'amabara, kandi ubushyuhe bwo gukaraba bushobora kugera ku rwego rwa 4-5, naho ubushyuhe bwo gukaraba bushobora kugera ku rwego rwa 4. Itandukaniro ry'amabara ΔE (<1.5) rigaragazwa na spectrophotometer, kandi uburebure bw'amabara y'ibara busesengurwa hakoreshejwe spectroscopy ya infrared kugira ngo harebwe ko ishusho iramba.
III. Ibyiza bya tekiniki n'imbogamizi
Ibyiza.
1. Kurengera ibidukikije no gukora neza cyane: nta gukaraba, ugereranije n'amazi asanzwe yo gucapa, bigabanya 95%, imyuka ihumanya ikirere ya VOC yagabanutseho 80%.
2. Imiterere y'amabara: Imirongo mito cyane ya 0.1mm n'amabara arenga 90%, cyane cyane ko ari meza mu rumuri rw'icyuma, uburebure bw'urumuri n'izindi ngaruka zikomeye.
Inzitizi:
Imbogamizi za Fibre: Fibre karemano (nk'ipamba) zifite ibara riri munsi ya 30%, kandi spandex zirenga 30% mu mvange za polyester-spandex zizatuma ibara rigabanuka.
Ibiciro: Igiciro cy'impapuro zo kohereza giteranya 35%-40% by'ikiguzi cyose cyo gukora, kandi igiciro cy'irangi ritambitse kiri hejuru ya 20% ugereranyije n'irangi rikoreshwa mu gukora.
IV. Uburyo bushya bwo gukoresha
Ku ikusanyirizo ryayo ryo mu mpeshyi/impeshyi 2025, ikirango cy’Abataliyani La Perla gikoresha ikoranabuhanga ryo gushyushya ubushyuhe kugira ngo cyongere Monet's Water Lilies mu mwenda wo kogana wa polyester-ammonia (78% polyester + 22% spandex), ugenzurwa neza n’ubushyuhe kuri 230°C/28s, ku buryo ishusho igumana 95% by’amabara nyuma yo kwibizwa mu mazi yo mu nyanja inshuro 10.
Niba nawe ushakaumwenda wo kogana wo mu rwego rwo hejuruKugira ngo ubone icapiro rya sublimation, reba hano hepfo iyi link y'ibicuruzwa byacu:
V. Iterambere ry'ejo hazaza rijyanye n'iterambere
1. Kuvugurura inzira zikoreshwa mu kubungabunga ibidukikije
Ibyuka bihumanya ikirere bishobora kugabanukaho 42% hakoreshejwe amarangi akoreshwa mu binyabuzima (nk'ubwoko bwa Clariant's Vat Eden) n'imigozi ya polyester ikoreshwa mu kongera gukoreshwa. Umuryango w'Ubumwe bw'u Burayi urateganya gushyiraho ibiciro by'imyenda yacapwe mu buryo bw'ubushyuhe irimo polyester ikoreshwa mu kongera gukoreshwa irenga 30% guhera mu 2026.
Ubu Fuzhou Huasheng Textile ifite icyemezo cya GRS cyo gushyigikira ibikoresho bya polyester byasubiwemo. Twagiye duharanira ubucuruzi burambye kandi ibi si nk'icyerekezo cy'inganda gusa, ahubwo ni nk'icyerekezo cy'ejo hazaza.
Umwanzuro
Ikoranabuhanga ryo gucapa imyenda iboshye ya polyester/polyester-spandex ririmo kuvugurura inganda zo gucapa no gusiga amarangi ku myenda, rikagira imiterere y’ “ubuziranenge, imikorere myiza no gukomeza”. Hamwe n’ikoranabuhanga rya digitale, imikorere myiza, uburyo bwo guhuza ibintu, iyi gahunda izagaragaza ubushobozi bwinshi mu bijyanye no kwambara imyenda mu buryo bw’ikoranabuhanga, imyenda yo kwa muganga, nibindi, kugira ngo hatezwe imbere impinduramatwara mu nganda “z’imyenda + ikoranabuhanga”. Ibigo bigomba kwibanda ku guhindura ibikoresho mu buryo bw’ubwenge, ubushakashatsi no guteza imbere ibikoresho bibungabunga ibidukikije ndetse no guteranya ikoranabuhanga mu mpande zitandukanye, kugira ngo bibashe gufata iya mbere mu kuvugurura inganda ku isi.
Fuzhou Huasheng Textile ifite ubunararibonye bwinshi mu gukora, gukora ubushakashatsi no guteza imbere imyenda ya sublimation, ikaba igamije gutangaumwenda woroshye wo gukora imashini iboshye ya polyester/polyester spandexDore amwe mu mahuza y'imyenda yacu ikwiriye imyenda ya siporo ya sublimation.
