Polyester non-woven npuagfeem ntau yog hais txog cov ntaub polyester uas tsis yog-woven, thiab lub npe tseeb yuav tsum yog "non-woven fabric". Nws yog ib hom ntaub tsim yam tsis tas yuav tsum tau spinning thiab weaving. Nws tsuas yog orients los yog randomly npaj textile luv fibers los yog ntev fibers los tsim ib tug fiber network qauv, thiab ces siv txhua yam, thermal bonding, los yog tshuaj txoj kev los txhawb nws. Nws yog ib yam tshiab ntawm cov khoom siv fiber ntau nrog cov mos mos, breathable, thiab tiaj tus qauv, uas yog ncaj qha tsim los ntawm ntau yam fiber ntau mesh txoj kev thiab consolidation cov tswv yim siv high polymer slicing, luv fibers, los yog ntev filaments.
Polyester nonwoven npuag yog cov ntaub uas tsis yog-woven tsim los ntawm uniformly faib polyester filament ntawm lub khiav mesh ntaub nyob rau hauv ib tug tshwj xeeb kub thiab siab los ntawm cov khoom xws li ntsia hlau extruder thiab spinneret, tsim ib tug fluffy fiber mesh, thiab ces rov punctured los ntawm ib rab koob punching tshuab. Polyester non-woven npuag tsim los ntawm Jiamei Cov Khoom Tshiab muaj kev ua haujlwm zoo, dej zoo permeability, corrosion tsis kam, kev laus ua haujlwm, kev sib cais, tiv thaiv pom, kua dej, kev tiv thaiv, ruaj khov, ntxiv dag zog thiab lwm yam haujlwm, tuaj yeem hloov mus rau qhov tsis sib xws, tuaj yeem tiv thaiv kev puas tsuaj sab nraud thaum lub sij hawm tsim kho, creep yog me me, thiab tseem tuaj yeem tswj nws cov haujlwm qub nyob rau hauv lub sij hawm ntev load, yog li nws yog feem ntau siv raws li ru tsev.
Piv nrog rau lwm hom textile geotextiles thiab luv fiber ntau geotextiles,tsis woven polyestermuaj cov yam ntxwv hauv qab no:
(1) Lub zog tensile siab: Piv nrog luv fiber ntau geotextiles ntawm tib qib, lub zog tensile yog nce los ntawm 63%, lub kua muag kuj nce los ntawm 79%, thiab sab saum toj tawg kuj yog nce los ntawm 135%.
(2) Kev ua haujlwm kub zoo: Nws muaj qhov muag muag siab tshaj 238 ℃, thiab nws lub zog tsis txo qis ntawm 200 ℃. Tus nqi thermal shrinkage tsis hloov qis dua 2 ℃.
(3) Kev ua haujlwm zoo heev: Lub zog yuav tsis txo qis tom qab siv mus ntev.
(4) Muaj zog corrosion kuj.
(5) Zoo durability, thiab lwm yam.
Cov txheej txheem dej tsis sib cais muaj nyob nruab nrab ntawm lub ru tsev waterproof txheej thiab cov txheej tiv thaiv nruj saum toj no. Cov txheej txheem nruj ntawm qhov chaw (feem ntau yog 40mm tuab zoo sib sau ua ke) yuav raug thermal expansion thiab contraction deformation. Thaum tsim lwm cov txheej txheem ntawm cov txheej txheem dej, txhawm rau kom tsis txhob ua rau cov txheej txheem dej tsis zoo, polyester non-woven npuag feem ntau yog tsim los rau kev tiv thaiv tsim nyog, nrog qhov hnyav ntawm 200g / ㎡. Polyester non-woven npuag feem ntau yog qhov ntxeem tau thiab permeable nruab nrab, uas tuaj yeem sau cov dej thiab tawm ntawm cov av thaum faus rau hauv. Lawv tuaj yeem tsis tsuas yog ntws raws cov kev taw qhia perpendicular rau lawv lub dav hlau, tab sis kuj raws lawv lub dav hlau kev taw qhia, uas txhais tau hais tias lawv muaj kab rov tav ua haujlwm. Ntev filament geotextiles tau dav siv rau kev tso dej thiab sib sau ua ke ntawm lub ntiaj teb dams, roadbeds, tuav phab ntsa, thiab cov hauv paus av mos. Polyester non-woven npuag muaj lub zog tensile siab, zoo tshav kub tsis kam, zoo heev creep kev ua tau zoo, thiab muaj zog corrosion kuj. Zoo durability, siab porosity, thiab zoo hydraulic conductivity yog zoo tagnrho lim cov ntaub ntawv rau cog av. Yog li ntawd, nws yog dav siv nyob rau hauv lub tsev ru tsev vov tsev boards, asphalt txoj kev, txuas hniav, kev txuag dej thiab lwm yam kev tsim kho tej yaam num.
