I. Chidule cha ukadaulo wosindikiza wa Sublimation
Kusindikiza kwa sublimation ndi mtundu watsopano wa njira yosindikizira kutengera mawonekedwe a sublimation a utoto wofalikira. Mfundo yaikulu ndikuyika sublimation ya utoto mwachindunji kuchokera ku mkhalidwe wolimba kupita ku mkhalidwe wa gasi kudzera kutentha kwakukulu (180-230℃), komwe kumalowa mkati mwa ulusi wopangidwa ndikulimba. Kuyambira pomwe idayamba kugwiritsidwa ntchito m'ma 1970, ukadaulo uwu wakhala njira yabwino kwambiri yosindikizira nsalu zosakanikirana za polyester ndi polyester-spandex chifukwa cha kusamala kwake chilengedwe (popanda kutsuka, palibe kutuluka kwa madzi otayira) komanso mawonekedwe ake olondola kwambiri.
Kugwiritsa ntchito nsalu za polyester ndikodziwika kwambiri, chifukwa kapangidwe kake ka molekyulu kakukula kwa kutentha kwambiri, kuti kathandize kulowa kwa mamolekyu a utoto; ndipo nsalu za polyester-Spandex (zosakaniza za polyester zokhala ndi spandex) ziyenera kuwonetsetsa kuti kuchuluka kwa polyester sikochepera 70%, kuti zitsimikizire kuti utotowo umayamwa bwino. Poyerekeza ndi kusindikiza kwachikhalidwe, kusindikiza kwa Sublimation kumatha kupanga maola 72 mosalekeza, liwiro limatha kufika 2000-3000 m / h, ndipo mawonekedwe ake ali ndi mphamvu yowonjezereka, mphamvu ya gradient ya masitepe 256 amitundu.
II. Njira ndi ukadaulo wofunikira
1. Pre-mankhwala ndi kusankha zinthu
Nsalu zolukidwa ndi polyester-spandex ziyenera kuphikidwa bwino, kupangidwa ndi makulidwe osiyanasiyana kuti zithetse mavuto a weft skew ndi rolled edges. Kugwiritsa ntchito makina osindikizira a digito okhala ndi cholembera cholowera mkati kungathandize kuti nsaluyo ikhale yosalala bwino ndikuchepetsa kufananiza mitundu. Pepala losamutsira limapangidwa ku Holland lolimba kutentha kwambiri ndipo limakutidwa ndi silicone layer kuti liwonjezere mphamvu ya utoto kutulutsa.
2. Kapangidwe ka digito ndi kusindikiza
Mukamaliza kupanga mapangidwe pogwiritsa ntchito pulogalamu ya CAD, mutu wosindikizira wa 720dpi x 720dpi wolondola kwambiri umagwiritsidwa ntchito kusindikiza inki yopaka utoto papepala losamutsira. Chisamaliro chiyenera kuperekedwa pa kapangidwe ka chithunzi chagalasi (horizontal flip) kuti chigwirizane ndi njira yosamutsira yotsatira, pamene mukulamulira kukhuthala kwa inki pakati pa 3-10mPa-s kuti mutu wosindikiza usatseke.
3. Njira yosamutsira atolankhani kutentha
Kutentha kwa kusamutsa nthawi zambiri kumakhala pa 180-210℃, kuthamanga kumayendetsedwa pa 10-12kPa, ndipo nthawi imasinthidwa kukhala masekondi 20-45 kutengera makulidwe a nsalu. Zipangizo zopopera mpweya (13.3kPa) zimatha kusintha kwambiri momwe utoto umalowera, makamaka pa nsalu za polyester-spandex kuti zisamaume. Potengera nsalu za polyester-spandex mwachitsanzo, kuchuluka kwa polyester kungagwiritsidwe ntchito ndi magawo a 180-210°C/30s, pomwe zovala zamasewera zopopera mpweya zimafuna nthawi yochepa kuti spandex isawonongeke.
4. Kumaliza ndi kuwongolera khalidwe
Kukhazikika kwa kutentha kwambiri (150-180℃/2min) kumafunika mutasintha kuti muwonjezere kulimba kwa utoto, ndipo kulimba kwa kupukuta kumatha kufika pamlingo wa 4-5, ndipo kulimba kwa kusamba kumatha kufika pamlingo wa 4. Kusiyana kwa mtundu ΔE (<1.5) kumadziwika ndi spectrophotometer, ndipo kuzama kwa kulowa kwa mamolekyu a utoto kumafufuzidwa ndi infrared spectroscopy kuti zitsimikizire kulimba kwa kapangidwe kake.
III. Ubwino ndi zofooka zaukadaulo
Ubwino.
1. Kuteteza chilengedwe ndi magwiridwe antchito apamwamba: palibe njira yotsukira, poyerekeza ndi madzi osindikizira achikhalidwe omwe amasunga 95%, mpweya wa VOC umachepetsedwa ndi 80%.
2. Mawonekedwe a utoto: mizere yopyapyala kwambiri ya 0.1mm komanso kukhuta kwa utoto kopitilira 90%, makamaka bwino pa kunyezimira kwachitsulo, kuwala kowala bwino komanso zotsatira zina zovuta.
Zoletsa:
Zoletsa za Ulusi: Ulusi wachilengedwe (monga thonje) uli ndi utoto wochepera 30%, ndipo mitundu yoposa 30% ya spandex mu polyester-spandex imapangitsa kuti mtundu usavutike kwambiri.
Zinthu Zokhudza Mtengo: Mtengo wa pepala losamutsira umakhala 35%-40% ya mtengo wonse wopangira, ndipo mtengo wa utoto wofalikira ndi wokwera ndi 20% kuposa utoto wosinthika.
IV. Zochitika zatsopano zogwiritsira ntchito
Pa zosonkhanitsira zake za masika/chilimwe 2025, kampani yaku Italy ya La Perla imagwiritsa ntchito ukadaulo wotenthetsera kutentha kuti ipange Monet's Water Lilies mu suti yosambira ya polyester-ammonia (78% polyester + 22% spandex), yomwe imayendetsedwa bwino ndi kutentha pa 230°C/28s, kotero kuti mawonekedwewo amasunga 95% ya utoto wake atamizidwa m'madzi a m'nyanja ka 10.
Ngati mukufunansonsalu yosambira yapamwamba kwambiriKuti musindikize sublimation, chonde onani ulalo wazinthu zathu pansipa:
V. Zochitika zamtsogolo pa chitukuko
1. Kusintha kwa njira zobiriwira
Utsi wa kaboni ukhoza kuchepetsedwa ndi 42% pogwiritsa ntchito utoto wosakaniza wa bio-based dispersive (monga Clariant's Vat Eden range) ndi ulusi wa polyester wobwezeretsedwanso. EU ikukonzekera kuyambitsa zokonda zamitengo ya nsalu zosindikizidwa za heat sublimation zomwe zili ndi polyester yobwezeretsedwanso yoposa 30% kuyambira 2026.
Fuzhou Huasheng Textile pakadali pano ili ndi ziphaso za GRS zothandizira zinthu zobwezerezedwanso za polyester. Nthawi zonse takhala odzipereka ku machitidwe abizinesi osamalira chilengedwe ndipo timaona izi osati ngati chizolowezi chokha, komanso ngati njira yosapeŵeka yamtsogolo yamakampani.
Mapeto
Ukadaulo wosindikiza nsalu zopangidwa ndi polyester/polyester-spandex ukusintha makampani osindikiza ndi kupaka utoto ndi makhalidwe a "kulondola, kuchita bwino komanso kukhazikika". Ndi ukadaulo wa digito, wogwira ntchito, kuya kwa kuphatikizana, njirayi idzawonetsa kuthekera kwakukulu m'munda wa zovala zanzeru, nsalu zamankhwala, ndi zina zotero, kuti ipititse patsogolo kusintha kwa mafakitale a "nsalu + ukadaulo". Mabizinesi ayenera kuyang'ana kwambiri pakusintha kwanzeru kwa zida, kafukufuku ndi chitukuko cha zinthu zosawononga chilengedwe komanso kuphatikiza ukadaulo wosiyanasiyana, kuti atsogolere pakukweza mafakitale padziko lonse lapansi.
Fuzhou Huasheng Textile ili ndi luso lochuluka pakupanga, kufufuza ndi chitukuko cha nsalu zogwiritsidwa ntchito popanga sublimation, zodzipereka kuperekaNsalu yapamwamba kwambiri ya polyester/polyester spandex yoluka yopangidwa ndi sublimationNazi maulalo ena a nsalu zathu zoyenera mayunifolomu amasewera a sublimation.
