Breathable bonding mesh, ua haujlwm txawv ntawm cov nplaum nplaum nplaum nplaum, yog cov txheej txheem thermoplastic web tsim los ntawm yaj- tshuab los yog reactive extrusion los pab txhawb cov khoom lamination thaum khaws cia cov macro-porosity ntawm cov cab kuj substrates. Los ntawm kev siv cov ntaub ntawv uas tsis yog -woven, randomized filament geometry, cov yeeb yaj kiab mesh no muab lub zog tev siab (15-30 N / 25mm) yam tsis muaj qhov sib txuas ntawm qhov sib txawv hauv cov ntaub qhwv. Qhov no tso cai rau kev hloov pauv tsis tu ncua ntawm cov vapor thiab huab cua ( ntsuas hauv $ cm ^ 3 / cm ^ 2 / s $), qhov kev xav tau tseem ceeb rau cov khau ua haujlwm siab thiab cov khoom siv sib xyaw ua ke uas cov txheej txheem thermal yog qhov tseem ceeb.
Porous Geometry thiab Structure Mechanics
Qhov "breathability" ntawm aKub Melt Webyog qhov tshwm sim ncaj qha ntawm nws qhov aperture piv thiab fiber ntau txoj kab uas hla. Tsis zoo li cov yeeb yaj kiab monolithic uas tsim ib qho kev thaiv tag nrho, cov qauv mesh muaj kev sib tshuamPolyamide (PA), Polyester (PES), los yogTPUfilaments uas nyob tsuas yog 30% mus rau 60% ntawm tag nrho cov cheeb tsam.
Filament Txoj kab uas hla:Feem ntau yog li ntawm 10µm mus rau 50µm kom sib npaug cov nplaum ntim nrog yooj.
Web Nyhav (gsm):Qhov hnyav dua (15-25 gsm) ua qhov tseem ceeb tshaj plaws hauv huab cua, thaum hnyav dua (40-80 gsm) yog siv rau cov khoom siv hnyav hnyav uas yuav tsum tau ua kom zoo dua.tensile zog.
Lub Hoobkas ncaj qha khoom ntawm Oeko-Tex tau ntawv pov thawj breathable mesh.

Sib npaug Adhesion nrog Moisture Vapor Transmission (MVT)
Thawj qhov kev sib tw engineering hauv [Insert Link:Mesh zaj duab xis] daim ntawv thov yog qhov "saturation point"-the theem uas nce nplaum hnyav inhibits breathability ntawm lub ntsej muag ntaub.
1. Tswj Thermal Flow
Thaumkub-nias kev sib txuas, qhov kub thiab txias yuav tsum tau ntsuas kom ncav cuag lub polymer lub softening point yam tsis tau mus txog lub xeev tag nrho cov kua. Qhov no ua kom cov filaments tuav lawv "web" architecture thiab tsis tawg mus rau hauv ib txheej txheej zaj duab xis.
2. Kev Tswj Siab
Nip siab yuav tsum tau tswj ntawm 2.0 thiab 4.0 bar. Lub siab ntau dhau ua rau cov molten polymer rau hauv cov ntaub lub qhov hws, txo cov huab cua permeability ntawm qhov kawg sib xyaw txog li 40%.
3. Substrate Synergy
Breathable mesh yog qhov zoo tshaj plaws thaum ua ke nrog qhib - cell foams lossis 3D-knit meshes. Piv txwv li, siv 15gsm TPU lub vev xaib los khi 3D-knit sab sauv khaws 90% ntawm cov khoom qub knit airflow thaum muab cov qauv kev txhawb nqa uas xav tau rau Tier-1 kis las khau.
Kev Siv Khoom Siv Scopes
Nkawm khau:Lamination ntawm breathable hauv ob sab phlu thiab ntiv taw -box reinforcements.
Khaub ncaws:Kev sib khi ntawm cov dej noo- cov khaubncaws sab nraud povtseg hauv hauv paus- khaub ncaws ncaws pob.
Automotive:Headliners thiab acoustic panels xav tau huab cua - pauv peev xwm.
Kev kho mob:Transdermal thaj backings thiab phais lub tsho lamination.
FAQ
Q1: Kuv yuav xaiv li cas ntawm PA thiab PES rau daim ntawv thov mesh?
Xaiv PA (Polyamide) rau qhov kub ua kom qis (95℃-}115 degree) thiab softness superior. Xaiv PES (Polyester) yog tias daim ntawv thov xav tau siab - ntxuav qhov kub (90 degree) lossis sib txuas rau PET-raws li cov khoom siv hauv tsev.
Q2: Puas yog koj lub mesh breathable ua raws li GRS cov qauv kev ruaj ntseg?
Yog lawm. Peb muabGRSCov ntawv pov thawj ntawm peb cov PES mesh ua los ntawm kev tshaj tawm - cov neeg siv khoom siv dua tshiab. Tag nrho cov variants kuj yogOeko-Tex Standard 100tau ntawv pov thawj, xyuas kom tsis muaj kev phom sij tshuaj lom neeg tsiv teb tsaws thaum ua haujlwm thermal.
Q3: Dab tsi yog qhov dav tshaj plaws rau kev lag luam lamination?
Peb cov qauv tsim dav yog 150cm, tab sis peb tuaj yeem muab kev cai slitting los ntawm 10mm mus txog 3200mm kom haum rau loj - nplai tsheb lossis cov kab sib xyaw.
