Synthetic tawv yog cov khoom siv uas simulates cov qauv thiab cov khoom ntawm ntuj tawv los ntawm cov khoom siv hluavtaws. Nws yog feem ntau siv los hloov cov tawv tiag tiag thiab muaj qhov zoo ntawm cov nqi tswj tau, kho tau zoo, thiab kev sib txawv ntawm ib puag ncig. Nws cov txheej txheem tseem ceeb suav nrog peb cov kauj ruam: kev npaj substrate, txheej txheej lamination, thiab nto tiav. Cov hauv qab no yog ib qho kev ntsuam xyuas los ntawm cov txheej txheem kev faib tawm mus rau cov txheej txheem cov ntsiab lus:

Daim ntawv thov: Ordinary PU tawv substrate
-Island-hauv-Hiav txwv fiber ntau spinning:
PET (Island) / PA ( hiav txwv) sib xyaw spinning yog ua, thiab "hiav txwv" tivthaiv yog yaj los ntawm hnyav los ua 0.01-0.001 dtex microfibers. Daim ntawv thov: Core substrate rau microfiber tawv (simulated tawv collagen fibers)
2. Cov txheej txheem ntub dej (Key Breathable Technology):
Lub hauv paus ntaub yog impregnated nrog PU slurry → immersed nyob rau hauv ib tug DMF / H₂O coagulation da dej → DMF precipitates los tsim ib tug microporous qauv (pore loj 5-50μm).
Nta: Breathable thiab ya raws-permeable (> 5000g / m² / 24h), haum rau high-end khau tawv thiab automotive interiors.
- Txheej txheem qhuav:
-Tom qab txheej, PU slurry yog kub-cua qhuav (120-180 ° C) kom evaporate cov kuab tshuaj thiab tsim ib zaj duab xis.
-Feature: High du nto, haum rau lub nra thiab cov khoom siv hluav taws xob. 3. Nto tiav
Embossing: High-temperature pressing (150 ° C) nrog steel pwm tsim ib simulated cowhide/crocodile tawv zoo nkauj, haum rau lub rooj zaum fabrics thiab khau uppers.
Printing: Gravure / digital inkjet luam ntawv tsim cov xim gradient thiab cov qauv kev cai, haum rau cov hnab tes zam thiab khaub ncaws.
Polishing: Sanding nrog ib tug emery roller (800-3000 grit) tsim ib tug waxy, ntxhov siab vim, haum rau vintage rooj tog tawv.
Cov Txheej Txheem Ua Haujlwm: Ntxiv nano-SiO₂ / fluorocarbon resin tsim hydrophobic (hu rau lub kaum sab xis> 110 °) thiab cov nyhuv tiv thaiv fouling, haum rau cov khoom siv sab nraum zoov thiab khoom siv kho mob.
III. Cov txheej txheem tshiab tshiab
1. 3D Printing Additive Manufacturing
- Siv TPU / PU composite filament, ncaj qha luam ntawv ntawm hollow "bionic tawv" txo qhov hnyav los ntawm 30% thiab txhim kho kev ua haujlwm zoo (xws li Adidas Futurecraft 4D khau sab saud). 2. Bio-based Synthetic tawv txheej txheem
- Base Fabric: Pob kws Fiber Non-Woven Fabric (PLA)
- Txheej: Dej-raws li Polyurethane (PU) Derivative los ntawm Castor Roj
Nta: Biochar Cov ntsiab lus> 30%, Compostable (piv txwv li, Bolt Xov Mylo ™)
3. Ntse Responsive Txheej
- Cov Khoom Siv Thermodynamic: Microcapsules Encapsulating Thermosensitive Pigments (xim hloov pauv ± 5 ° C)
- Photoelectric Txheej: Embedded Conductive Fibers, Kov-Controlled Illumination (Interactive Panels hauv Automotive Interiors)
IV. Kev cuam tshuam ntawm txheej txheem ntawm kev ua haujlwm
1. Tsis txaus Coagulation ntub dej: Tsis zoo Micropore Connectivity → Txo cua permeability. Kev daws: DMF Concentration Gradient Control (5% -30%).
2. Rov qab siv cov ntawv tso tawm: Txo cov ntaub ntawv ntshiab. Kev daws: Siv Txhua Yob ≤3 Sijhawm (2μm Qhov Tseeb).

- Xaiv cov yuam sij:
- Siab hnav tsis kam → Microfiber tawv (tuag zog> 80N / mm);
- Ib puag ncig qhov tseem ceeb → Dej-raws li PU + cov ntaub ntawv siv dua tshiab (Blue Label certified);
- Tshwj xeeb nta → Ntxiv nano-coatings (hydrophobic/antibacterial/thermosensitive).
Cov txheej txheem yav tom ntej yuav nrawm rau kev hloov kho digital (xws li AI-powered kev ntxhib los mos tsim) thiab xoom-pollution manufacturing (kaw-loop hnyav rov qab).
