Kev nthuav dav ntawm PU / Synthetic Tawv Rau Cov Khoom Siv Hnab
1.Composition & Structure
PU (Polyurethane) Synthetic Leather, tseem hu ua PU Leather lossis Artificial Leather, yog qhov tseem ceeb ntawm nws cov ntsiab lus polyurethane. Nws cov qauv feem ntau muaj ntau txheej txheej:
Base Fabric Layer: Qhov no yog lub hauv paus "skeleton" thiab kev txhawb nqa. Nws feem ntau yog ua los ntawm knitted, woven, los yog tsis yog -woven fabrics (xws li polyester, nylon, paj rwb, los yog blends). Lub hauv paus ntaub muab lub zog tensile, toughness, thiab seem stability.
Cov Txheej Txheem Nruab Nrab (Npuas Ncauj Txheej - Xaiv tab sis Feem Ntau): Muab tso rau ntawm lub hauv paus ntaub thiab txheej txheej. Cov txheej no feem ntau yog tsim los ntawm foaming polyurethane resin, tsim kom muaj cov qauv microporous. Nws yog ib qho tseem ceeb rau imparting softness, elasticity, plump handfeel (zoo li lub cev nqaij daim tawv tiag), thiab qee qhov thermal rwb thaiv tsev. Lub thickness thiab ntom ntawm cov txheej no ncaj qha cuam tshuam rau qhov kawg ntawm cov khoom firmness thiab resilience.
Nto Txheej / Txheej: Qhov no yog qhov tseem ceeb pom thiab tactile txheej. Cov tshuaj polyurethane resin yog siv rau lub hauv paus ntaub los yog npuas txheej ntawm txheej txheej (xws li, riam- txheej, cov menyuam- txheej) los yog impregnation. Cov txheej txheem tom qab muaj xws li coagulation, ntxuav, ziab, thiab feem ntau embossing (kom ua raws li cov tawv tawv zoo li pebbled, crosshatch, los yog rub-txog cov teebmeem, lossis lwm yam kev ua kom zoo nkauj) thiab ua kom tiav (xws li, dyeing, printing, spraying, polishing, matting, laminating). Qhov no ua rau qhov kawg "daim tawv nqaij" nrog cov xim tshwj xeeb, sheen, kev ntxhib los mos, thiab cov khoom nto.
Hauv cov ntsiab lus: PU Synthetic Leather yog cov khoom siv tawv tawv uas tsim los ntawm kev sib koom ua ke ntawm polyurethane resin thiab nws cov txheej ua npuas dej rau hauv cov ntaub los yog cov ntaub tsis yog -woven npuag substrate los ntawm impregnation lossis txheej txheej txheej, ua raws li tom qab- kev kho mob (embossing, deg xov).
