Kuprinda Nzira
Tekinoroji, kune nzira dzinoverengeka dzekudhinda, senge kudhinda kwakananga, kuburitsa kudhinda uye kuramba kudhinda.
Mukudhinda zvakananga, kudhinda paste kunofanira kutanga kugadzirirwa.Paste, senge alginate paste kana starch paste, inoda kusanganiswa muchikamu chinodiwa nedhayi uye mamwe makemikari anodiwa senge wetting agents uye fixing agents.Izvi zvinobva zvadhindwa pamucheka muchena wepasi maererano nemagadzirirwo anodiwa.Kune machira ekugadzira, iyo yekudhinda paste inogona kugadzirwa nepigment pachinzvimbo chedhayi, uye ipapo kudhinda paste kungave ne pigment, adhesives, emulsion paste uye mamwe makemikari anodiwa.
Mukudhinda kudhinda, jira repasi rinofanira kutanga rakadhayiwa nemuvara wepasi waunoda, uye ipapo ruvara rwepasi runobudiswa kana kusvibiswa munzvimbo dzakasiyana-siyana nekuridhinda nekapu yekubuda kuti usiye madhizaini anodiwa.Iyo dischargepaste inowanzogadzirwa neinoderedza ejenti senge sodium sulphoxylate-formaldehyde.
Mukuramba kudhinda.zvinhu zvinopikisa kudhayi zvinofanira kutanga kuiswa pamucheka wevhu, uye ipapo jira rinodhayiwa.Mushure mokunge jira rave rakadhayiwa, kupikisa kuchabviswa, uye magadzirirwo anoonekwa munzvimbo dzakadhindwa kupikisa.
Kunewo mamwe marudzi ekudhinda, semuenzaniso, sublistatic kudhinda uye kudhinda kweboka.Mukona, dhizaini inotanga kudhindwa papepa uyezve bepa rine magadzirirwo anotsikirirwa pamucheka kana zvipfeko zvakaita seT-shirts.Kana kupisa kunoshandiswa, magadzirirwo acho anotamirwa pamucheka kana nguo.Mukupedzisira, shourt fibrous zvinhu zvinodhindwa mumaitiro pamicheka nerubatsiro rwekunamatira.Electronstatic flocking inowanzoshandiswa.
Midziyo Yokudhinda
Kudhinda kunogona kuitwa neroller printing, screen printing kana, munguva pfupi yapfuura, inkjet kudhinda michina.
1. Roller Printing
Muchina wekudhinda weroller unowanzo sanganisira silinda hombe yepakati (kana inodaidzwa kuti mbiya yekumanikidza) yakavharwa nerabha kana matinji akati wandei emucheka-werineni akasanganiswa mucheka anopa silinda ine yakatsetseka uye inotsikirira elastic pamusoro.Mapepa emhangura akati wandei akanyorwa nemadhizaini anodhindwa anogadzikwa akatenderedza silinda yekumanikidza, roller imwe yeruvara rumwe nerumwe, inosangana nepumburu yekumanikidza.Sezvavanotenderera, imwe neimwe yakavezwa roller yokudhinda, inotyairwa zvakanaka, inotyairawo furnisher roller yayo, uye iyo yekupedzisira inotakura paste yekudhinda kubva mubhokisi reruvara kuenda kune yakavezwa roller yekudhinda.Chipenga chesimbi chinopinza chinonzi chekuchenesa chiremba blade chinobvisa paste yakawandisa kubva paprinting roller, uye imwe blade inonzi lint chiremba blade inokwenya chero lint kana tsvina inobatwa neinodhinda roller.Iro jira rinodhindwa rinodyiswa pakati pemapumburu ekudhinda uye silinda yekumanikidza, pamwe chete nemucheka wegrey wekudzivirira kudzivirira pamusoro pehumburumbira kuti isasvibiswa kana peta yemavara ikapinda mumucheka.
Roller kudhinda kunogona kupa chibereko chepamusoro-soro asi kugadzirirwa kweakavezwa kudhinda rollers kunodhura, izvo, chaizvoizvo, zvinoita kuti zvienderane nekugadzirwa kwenguva refu.Uyezve, iyo dhayamita yeinodhinda roller inoganhura saizi yemuenzaniso.
2. Screen Printing
Screen printing, kune rumwe rutivi, inokodzera maodha madiki, uye inonyanya kukodzera kudhinda machira akatambanudza.Mukudhinda skrini, zvisikirini zvakarukwa zvemesh zvinofanirwa kutanga zvagadzirirwa zvinoenderana nemagadzirirwo achadhindwa, imwe yeruvara rumwe.Pasikirini, nzvimbo dzisina pemese yemavara dzinofanira kupinda dzakaputirwa nefirimu isinganyungudika ichisiya yasara sikirini yakavhurika kuti inodhinda paste ipinde mazviri.Kudhinda kunoitwa nekumanikidza yakafanira kudhinda paste kuburikidza ne mesh pateni pajira riri pazasi.Chidzitiro chinogadzirwa nekuputira skrini ne photogelatin kutanga uye nekusimudzira mufananidzo wakashata wedhizaini pairi uye wozoisa pachena kuchiedza chinogadzirisa uye chisinganyunguke bhaisikopo rekuputira pachiratidziri.Iyo yekupfekedza inogezwa kubva munzvimbo dziya dzisina kuporeswa, zvichisiya mainterstices ari muchiratidziro akavhurika.Traditional screen printing is flat screen printing, asi rotary screen printing inofarirwawo zvakanyanya nekukura kukuru.
3. Inkjet Printing
Zvinogona kuonekwa kuti kune imwe roller printing kana screen-printing kugadzirira inguva uye mari inopedza kunyange zvazvo zvirongwa zveComputer Aided Design (CAD) zvakashandiswa zvakafara mumafekitari akawanda okudhinda kuti abatsire mukugadzirira kwekugadzira.Magadzirirwo anofanira kudhindwa anofanirwa kuongororwa kuti asarudze kuti ndeapi mavara angave akabatanidzwa, uye ipapo mapatani asina kunaka anogadzirirwa kune rumwe ruvara rweruvara uye oendeswa kune anodhinda rollers kana masikirini.Munguva yekudhinda skrini mukugadzirwa kwakawanda, kutenderera kana kufuratirwa, masikirini anofanirwa kuchinjwa uye kucheneswa kazhinji, zvinova zvakare nguva uye basa rinodya.
Kuti usangane nemusika wemazuva ano kudiwa kwekupindura nekukurumidza uye diki batch saizi inkjet yekudhinda tekinoroji iri kuwedzera kushandiswa.
Inkjet kudhinda pamachira kunoshandisa tekinoroji yakafanana neiyo inoshandiswa mukudhinda mapepa.Ruzivo rwedhijitari yedhizaini yakagadzirwa uchishandisa CAD system inogona kutumirwa kune inkjet printa (kana zvakanyanya kunzi dijitari inkjet printer, uye machira akadhindwa nawo anogona kunzi semachira edhijitari) zvakananga uye kudhindwa pamachira.Kuenzaniswa neyechinyakare matekinoroji ekudhinda, maitiro ari nyore uye nguva shoma uye hunyanzvi hunodiwa sezvo maitiro acho ari otomatiki.Uyezve, kusvibiswa kushoma kuchakonzerwa.
Kazhinji kutaura, kune maviri misimboti yekutanga inkjet kudhinda machira.Imwe ndeye Continuous Ink Jetting ( CIJ ) uye imwe inonzi "Drop on Demand" (DOD).Muchiitiko chekare, yakanyanya kudzvinyirira (yakatenderedza 300 kPa) inovakwa kuburikidza neingi yekupa pombi inomanikidza iyo ingi inoramba ichienda kumuromo, iyo dhayamita yaro inowanzosvika gumi kusvika zana micrometres.Pasi peiyo high frequency vibration inokonzerwa nepeizoelectric vibrator, iyo inki inozotyorwa kuita kuyerera kwemadonhwe uye inoburitswa kubva mumuromo nekumhanya kwakanyanya.Zvinoenderana nemagadzirirwo, komputa inotumira zvikwangwani kune electrode yekuchaja iyo inochaja nemagetsi madonhwe einki akasarudzwa.Kana uchipfuura nepama electrode anotsauswa, madonhwe asina kuchaja anoenda akananga mugomba rekunhonga nepo madonhwe einki akachajiwa achizotsauswa pajira kuti aite chikamu chepatani yakadhindwa.
Mune "kudonha pazvinoda", madonhwe einki anopihwa sezvinodiwa.Izvi zvinogona kuitwa kuburikidza ne electromechnical transfer nzira.Zvinoenderana nemapeteni anozodhindwa, komputa inotumira masaini masaini kune piezoelectric mudziyo uyo unozokanganisa uye unoburitsa kudzvanywa pakamuri yeinki kuburikidza neinochinjika yepakati zvinhu.Kumanikidza kunoita kuti madonhwe einki abudiswe kubva mumuromo.Imwe nzira inowanzoshandiswa muDOD tekinoroji iri kuburikidza nemagetsi ekupisa nzira.Mukupindura zviratidzo zvekombuta, hita inogadzira mabhubhu mukamuri yeinki, uye simba rakakura remafuro rinoita kuti madonhwe eingi abudiswe.
Iyo DOD tekinoroji yakachipa asi kumhanya kwekudhinda zvakare kwakadzikira pane iyo yeCIJ maitiro.Sezvo madonhwe einki achiramba achiburitswa, matambudziko ekuvhara mhino haaitike pasi pehunyanzvi hweCIJ.
Inkjet printers inowanzoshandisa musanganiswa wemavara mana, kureva, cyan, magenta, yero uye dema ( CMYK ), kudhinda magadzirirwo ane mavara akasiyana, uye saka mana anodhinda misoro inofanira kuunganidzwa, imwe yega yega.Zvakadaro mamwe maprinta ane 2*8 misoro yekudhinda kuitira kuti nedzidziso inosvika gumi nematanhatu mavara einki anogona kudhindwa.Iyo inodhinda sarudzo yeinkjet printer inogona kusvika 720 * 720 dpi.Iwo machira anogona kudhindwa neinkjet anodhinda anobva kune echisikigo shinda, sedonje, sirika nemvere dzemakwai, kusvika kune ekugadzira fibers, senge polyester uye polyamide, saka kune akawanda marudzi einki anoda kusangana nezvinodiwa.Izvi zvinosanganisira ingi dzinoshanda, ingi dzeasidhi, ingi dzekuparadzira uye kunyange ingi dzine pigmented.
Mukuwedzera kune machira ekudhinda, inkjet printers inogonawo kushandiswa kudhinda T-shirt, sweatshirts, polo shirts, kupfeka kwevana, apron uye tauro.
