Core-Sheath Continuous Filament Technology
PET Continuous Filament Felt yog tsim los nrog LMPET / PET core - sheath composite- spinning technology. Txhua qhov txuas txuas txuas ntxiv muaj qhov qis- melting-point copolyester sheath thiab cov pa siab siab -melting-point PET core.
Qhov ntev ntawm lub filament tuaj yeem ncav cuag qib kilometer, tsim ib qho kev txuas ntxiv txuas ntxiv thoob plaws hauv kev xav.
Thaum lub sij hawm kub nias, qhov qis - melting- taw tes sheath softens thiab bonds cov kev sib tshuam filament. Lub siab - melting -point PET core khaws nws daim ntawv txuas ntxiv thiab muab lub ntsiab ntxiv.
Cov qauv no tsis tas yuav muaj cov nplaum ntxiv los tsim peb - cov khoom siv nrog qhov tawv, toughness, thiab kev cuam tshuam lub zog. Cov khoom tuaj yeem muab tau raws li cov khoom siv raw zoo siab lossis ntxiv nias rau hauv cov khoom siv hauv tsheb thiab peb - qhov seem tsim.
Adjustable Sheath- mus rau -Core Structure
Cov ntaub qhwv tuaj yeem yog LMPET lossis CoPET nrog lub melting -point range ntawm 110-180℃. Cov kev xaiv muaj xws li 110 degree, 130 degree, 150 degree, thiab 180 degree.
PET core muaj qhov melting point ntawm 256-260 degree. Muaj cov ntaub qhwv- rau- qhov sib piv tseem ceeb muaj xws li 50:50, 30:70, 20:80, thiab 10:90. Siab-kawg daim ntawv thov tsheb feem ntau siv qhov sib piv ntawm 10:90 thiab 30:70.
Los ntawm kev hloov qhov sib piv ntawm sheath, filament fineness, raw-xav lub hauv paus hnyav, thiab kub- nias ceev, cov khoom tuaj yeem hloov kho rau qhov xav tau yooj yim, suab- nqus cov liners, lossis cov khoom siv nruj.
Ib tug concentric core-cov qauv sheath muaj, thaum lub eccentric qauv kuj raug txiav txim raws li kev tsim.
Dimensions thiab Structure Performance
Raw-xav lub hauv paus hnyav li ntawm 150 txog 2,000 g / m², thiab cov tuab tuab ntawm 3 txog 50 hli. Qhov dav dav yog 1.0-4.2 m, thaum cov khoom siv hauv tsheb feem ntau siv dav ntawm 2.2-3.2 m. Yob ntev li ntawm 50 mus rau 200 m.
Qhov ceev ntawm cov khoom siv siab yog 0.02-0.10 g / cm³. Tom qab kub nias, qhov ceev tuaj yeem ncav cuag 0.5-0.9 g / cm³. Porosity yog 85% -98%.
Rau qib 1,200 g / m², molded ntom yog 0.60-0.70 g / cm³ thiab tsim thickness yog 1.8-2.2 hli. Lub zog tensile yog 28-38 MPa, flexural zog yog 35-48 MPa, thiab Charpy cuam tshuam lub zog yog 35-45 kJ / m².
PET Continuous Filament Felt yog tsim rau lub cav undercovers, tsheb sab shields, roj teeb -pack covers, spare- log covers, seat backs, and door-panel frames.
Integrated Khoom thiab Moulding Support
Jiangsu Haokai ua tiav PET txuas ntxiv - cov khoom siv fiber ntau thiab chav - cov kab molding hauv xyoo 2025.
Lub Hoobkas tuaj yeem txuas txuas mus ntxiv- fiber ntau ntau lawm, molding, precision tuag txiav, thiab ua tiav- khoom soj ntsuam hauv ib qhov project workflow.
Lub hauv paus hnyav, sheath-rau-core piv, thiab kub- txheej txheem nias tuaj yeem hloov kho raws li cov khoom siv thauj khoom, thickness, curvature, thiab qhov chaw teeb tsa.
Lub tuam txhab txhawb kev tsim pwm, qauv, kuaj xyuas, me me -batch ntau lawm, thiab ntim khoom xa tuaj. Cov duab lossis cov yeeb yaj kiab tuaj yeem muab tau.
Tag nrho cov khoom tau txais 100% kev tshuaj xyuas ua ntej packing, thiab thib peb -kev soj ntsuam tog tau txais. Ntim rau cov yob dav thiab cov khoom molded tuaj yeem tsim nyob ib puag ncig shipping qhov ntev, kev tiv thaiv ntug, thiab cov xwm txheej stacking.
