Synthetic dehwe chinhu chinoteedzera chimiro uye zvimiro zveganda rechisikigo kuburikidza neyakagadzirwa synthesis. Inowanzo shandiswa kutsiva dehwe rechokwadi uye ine mabhenefiti emitengo inodzoreka, inogadzirika kuita, uye kusiyana kwezvakatipoteredza. Iyo yakakosha maitiro inosanganisira matanho matatu: substrate kugadzirira, coating lamination, uye pamusoro pekupedzisira. Inotevera iongororo yakarongeka kubva kuclassification system kune iyo process details:
1. Core Classification yeSynthetic Leather
Mhando: Nubuck dehwe
Nubcuk dehwe/Yangba dehwe
Suede dehwe
Dehwe rakaiswa jecha/Dehwe rine chando
Space dehwe
Brushed PU dehwe
Varnish yeganda
Patent dehwe
Yakashambwa PU dehwe
Kupenga-bhiza dehwe
Blushed dehwe
Dehwe remafuta
Dhonza-up effect yeganda
PVC yeganda rekugadzira: jira rakarukwa/risina kurukwa + PVC paste, isingapindi mvura uye isingapfeki, inodhura, asi isingafemeki zvakanaka. Inokodzera zvifukidzo zvefenicha uye mukwende wakaderera.
Yakajairika PU yematehwe: jira risiri-rakarukwa + polyurethane (PU) coating, rakapfava uye rinofema, asi rinowanzo kuchembera uye kuputika. Bhutsu kumusoro, zvipfeko zvembatya
Fiber yeganda: Island-in-the-sea microfiber + impregnated PU, inotevedzera dehwe pore chimiro, abrasion uye kubvarura kuramba, yakakodzera shangu dzemitambo yepamusoro uye zvigaro zvemotokari.
Eco-synthetic dehwe: Yakadzokororwa PET base jira + mvura-yakavakirwa PU, biodegradable, yakaderera-VOC emissions, yakakodzera eco-hushamwari mabhegi uye zvigadzirwa zvekuzvara.
II. Core Production process Tsananguro Yakadzama
1. Substrate Kugadzirira Maitiro
Non-woven carding:
Polyester/nylon staple fibers anoiswa makadhi muwebhu uye anoroverwa tsono kuti asimbise (huremu 80-200g/m²).
Kushandisa: Yakajairika PU yematehwe substrate
-Island-in-the-sea fiber spinning:
PET (chitsuwa) / PA (gungwa) composite spinning inoitwa, uye chikamu che "gungwa" chinonyungudutswa ne solvent kuumba 0.01-0.001 dtex microfibers. Chishandiso: Core substrate ye microfiber yematehwe (yakafananidzwa yeganda collagen fibers)
2. Wet Process (Kiyi Inofema Technology):
Base jira rakaiswa nePU slurry → kunyudzwa muDMF/H₂O coagulation bath → DMF inonaya kuita microporous chimiro (pore size 5-50μm).
Zvimiro: Inofema uye mwando-inopindika (> 5000g/m²/24h), yakakodzera kune yakakwirira-yekupedzisira shangu dehwe uye motokari mukati.
- Dry process:
-Mushure mekuputira, iyo PU slurry inopisa-mhepo yakaomeswa (120-180 ° C) kuti ibudise iyo solvent uye kugadzira firimu.
-Zvinhu: Yakanyanya kutsetseka pamusoro, inokodzera mukwende uye zvemagetsi zvigadzirwa casings. 3. Surface Kupedzisa
Embossing: Kutsikirira kwepamusoro-soro (150 ° C) nesimbi mold inogadzira yakafananidzirwa yedehwe remombe / ngwena yeganda, inokodzera machira esofa uye pamusoro shangu.
Kudhinda: Gravure/digital inkjet kudhinda kunogadzira gradient mavara uye tsika mapatani, akakodzera mabhegi emafashoni uye zvipfeko.
Kupukuta: Sanding ine emery roller (800-3000 grit) inogadzira waxy, kushushikana mhedzisiro, yakakodzera kune vintage fenicha dehwe.
Functional Coating: Kuwedzera nano-SiO₂/fluorocarbon resin inogadzira hydrophobic (contact angle> 110 °) uye anti-fouling effect, yakakodzera midziyo yekunze uye mishonga yekurapa.
III. Innovative Process Mabudiro
1. 3D Printing Additive Manufacturing
-Kushandisa TPU/PU composite filament, kudhinda zvakananga kwe "bionic leather" isina huremu inoderedza huremu ne30% uye inovandudza kusimba (semuenzaniso, Adidas Futurecraft 4D shangu yepamusoro). 2. Bio-based Synthetic Leather Process
-Base Fabric: Chibage Fiber Chisina-Ruka Fabric (PLA)
-Kupfekedza: Mvura-Yakavakirwa Polyurethane (PU) Inotorwa kubva kuCastor Oiri
Zvimiro: Biochar Zvemukati> 30%, Compostable (semuenzaniso, Bolt Threads Mylo™)
3. Smart Inopindura Coating
- Thermodynamic Material: Microcapsules Encapsulating Thermosensitive Pigments (Muvara Shanduko Threshold ±5°C)
- Photoelectric Coating: Embedded Conductive Fibers, Touch-Controlled Illumination (Interactive Panels muMotokari Interiors)
IV. Impact of Process on Performance
1. Insufficient Wet Coagulation: Yakashata Micropore Connectivity → Yakaderedzwa Mhepo Permeability. Mhinduro: DMF Concentration Gradient Control (5% -30%).
2. Kushandisazve Pepa Rokusunungurwa: Yakaderedzwa Kujeka Kwekujeka. Mhinduro: Shandisa Imwe neimwe Roll ≤3 Nguva (2μm Kururama).
3. Solvent Residue: Yakawandisa VOCs (> 50ppm). Mhinduro: Kushambidza mvura + vacuum devolatilization (-0.08 MPa)
V. Environmental Upgrade Mazano
1. Raw Material Kutsiva:
- Solvent-based DMF → Mvura-based Polyurethane (90% VOC kuderedza)
- PVC Plasticizer DOP → Citrate Esters (Isina-chepfu uye Biodegradable)
2. Kudzokorodza Dombo reDehwe:
-Kupwanya zvimedu → Kudzvanya-kudzvanya mumasevhisi akadzokororwa (semuenzaniso, EcoCircle ™ tekinoroji, 85% yekudzoreredza mwero)
VI. Mamiriro ekushandisa uye Sarudzo Kurudziro
High-end Mota Zvigaro: Microfiber Leather + Wet-Process PU, Abrasion Resistance > 1 Million Times (Martindale)
Zvipfeko zvePanze Zvisina Mvura: Kutakurisa Coating + Fluorocarbon Surface Kurapa, Hydrostatic Pressure Resistance > 5000 Pa
Medical Antimicrobial Protective Gear: Nanosilver Ion-Impregnated Microfiber Leather, Antibacterial Rate > 99.9% (ISO 20743)
Fast Fashion Eco-Hushamwari Mabhegi | Yakagadzirwazve PET Base Fabric + Mvura-Yakavakirwa Dry Coating | Carbon Footprint <3 kg CO₂e/㎡ Pfupiso: Iwo musimboti wekugadzirwa kwematehwe ari musanganiswa we "structural biomimetic" uye "performance optimization."
-Basic process: Wet-process pore kugadzirwa kunoteedzera chimiro chinofema cheganda, ukuwo yakaoma-maitiro ekubatisa anodzora kurongeka kwepamusoro.
-Simudzira nzira: Microfiber substrates inosvika pakunzwa kwedehwe rechokwadi, ukuwo bio-based/hungwaru machira anowedzera miganhu inoshanda.
-Sarudzo Makiyi:
- Yakanyanya kupfeka inodzivirira zvinodiwa → Microfiber dehwe (kubvarura simba> 80N/mm);
-Kukosheswa kwezvakatipoteredza → Mvura-yakavakirwa PU + yakadzokororwa base jira (Blue Label yakasimbiswa);
- Akakosha maficha → Wedzera nano-coatings (hydrophobic/antibacterial/thermosensitive).
Mafambiro eramangwana ano mhanyisa akananga kudhijitari (yakadai seAI-powered mameseji kugadzirwa) uye zero-kusvibisa kugadzira (yakavharwa-loop solvent kupora).
