Dab ntawv DTF: Yuav ua li cas los txiav cov ntawv xim tshaj tawm li tib txhua hnub
Dab Ntawv DTF Yog Twg Thiab Nws Siv Li Cas Thiab Transfer Film?
DTF (Direct-to-Film) dab ntawv, cov ntawv siv rau kev xa tawm yog ib qho siv zoo uas muaj ntau qhov hauv nws: ua los ntawm PET Film raws li qhov chaw pib, adhesive coating thiab release layer. Thaum pib, nws siv kev xa tawm los ntawv thiab tom qab ntawd nws siv hluav taws los tso cai rau kev xa tawm. Qhov zoo tshaj ntawm DTF release paper yog tias nws muaj ib qho adhesive film, uas ua rau qhov teeb meem uas cov transfer film uas ua tib zoo siv rau DTG printing thiab dye sublimation, xav tau kev ua ntej thiab kev ua tom qab tso rau hauv qhov chaw.
| Feature | DTF daim ntawv | Txav Film |
|---|---|---|
| Qauv | Ntau npaug nrog kev siv cov roj adhesive | Ib npaug polymer |
| Kev hloov adhesive | Txhob ntawv | Xav tau ib qho ua ntej |
| Laij tawm Txoj kev | Heat-activated powder bonding | Kev ntxhov siab adhesive |
| Cov khoom siv Compatible | Cotton, polyester, blends | Tsuav nyob rau cov ntaub ntawv tshwj xeeb |
DTF xov tooj ua rau ntauv ntauv muaj qhob (40% siab dua) kom ntauv ntauv hauv qab tshuab (55% cotton/45% polyester).
Qhov cai nrog cov adhesive thiab cov ntaub qab tshuab rau ua kom ntauv ntauv zoo
Cov adhesive ua kom cov ntawv hluav taws mus rau hauv qab tshuab, cov ntauv ntauv zoo tshaj yog 0.3mm. Cov ntaub qab tshuab (18–22% silicone) ua kom cov ntawv tshuab tso tawm sai thiab zoo, tso cai rau cov ntaub ntauv ntauv zoo (0.1mm rau ntawv thiab cov ntaub ntauv ntauv zoo).
Cov cai tseem ceeb hauv kev tshuab ntauv ntauv:
- Adhesive sov mus rau ib qho chaw 160–165°C , ua kom cov ntawv ntauv ntauv zoo
- Cov ntaub qab tshuab ua kom muaj qhob (32–35 mN/m)
- Cov cai ua rau ntauv ntauv zoo 94-98% kev zoo siab ntawm lub ntsiab lus nyob rau hauv CMYK + White prints
Kev nqis no pab kom zoo siab, tso cai 50+ cov ntaub qab tshuab tsis txawv lossis dhos mus.
Cov khoom lag luam thiab kev xa mus rau DTF Printing
Kev xa cov khoom tshuab, tawv, thiab cov khoom siv rau kev nqus
DTF printing xav tau cov khoom lag luam ua haujlwm:
- Cov tshuab tawv paj rwb (six-channel: CMYK + white)
- 1200–2400 DPI kev ua haujlwm rpuv cov nta ntawv ntau
- Ink siv hluav taws xob (300% kev txhaws hauv qhov test)
- Tso kov tshuab ua haujlwm (110–120°C rau 2–3 feeb) rpuv 4.5/5 kev ua haujlwm huv
DTF Transfer Film thiab Powder: Sib phim cov khoom nrog DTF Paper
Txhim kho kev ua haujlwm los ntawm sib phim cov khoom sib raug:
| Kev Nyob Huv Khoom | Powder Siab (50µm) | Powder Thaj (65µm) |
|---|---|---|
| Zoo Li Cas | Kev Sau Siab Ntau | Thaj Lub Ntawv Sau Rau Kev Haus |
| Kev Teeb Tsa Txoj Keb | 145°C | 160°C |
| Ntau Ntim Ntau Txaj | 40+ | 25+ |
Tsis txhob siv cov duab pleev xim silicone nrog cov ntshav hlau ua ntej—qee cov neeg ua rau 37% cov kev phom sij hawm ua kom nyob .
Yuav ua li cas los tsim ib qhov chaw ua haujlwm uas muaj peev xwm kho kom zoo thiab muaj peev xwm zoo dua DTF Chaw Sau Ntshav
Ib qhov chaw ua haujlwm uas tau kho siab:
- Kho 24" loj dua tus kho tshuav ($1,800)
- Heat press ob theem ($700)
- Powder shaker/curing combo unit ($500)
Txhob Txhob 40–60% kev huv rau kev tiv thaiv ntawm cov duab ntawv. Cov neeg siv hais tias 23% siab dua kev tsim khoom nrog cov chaw ua haujlwm sab nraud.
Kauj Ruam Los Kauj Ruam DTF Qhia Cov Lus Txog Kev Huv Siab
Los ntawm Kev Sau Los Txog Qhia: Pov Tawm Cov Ntaub Ntawv Rau Kev Huv Siab
- 300+ DPI qhov chaw (cov ntaub ntawv vector xav tau rau kev hloov pauv ntau dua)
- Kev sau kab ntawv rau kev ua haujlwm rpuv kev ua kom yog raws li qhov chaw tswj
- Lub hom phiaj siv sijhawm CMYK (20–25% ntawv ua haujlwm rau cov ntawv hlau xim ntsuab)
Kev sau rau hauv DTF Paper: Zoo tshaj plaws
- Kuv 1.5–2mm lub qhov rai ntawm qhov chaw printhead thiab lub ntawv
- Sau nyob rau 25–28°C rpuv kev tshuag zoo tshaj plaws
- Ua 55–65% ink density rpuv rau kev ua siab thiab ua kev hlav dav
Kev ua kom sov thiab kev nyob ntawm qhob
| Qauv | Optimal Range | Puas yog li cas rau kev ua kom nqus |
|---|---|---|
| Lub qhob me me | 150–200 microns | Tiv thaiv kev tsis pom meej |
| Kev nqis siab | 0.8–1.2 bar | Paub txog cov khoom sib npaug |
| Nruab cov roj hmab | 12–15 seconds | Zog siab tus ntsuas |
