Geotextile, tseem hu ua geofabric, yog ua los ntawm cov hluavtaws fibers los ntawm kev siv los yog xaws ntawm cov ntaub ntawv dej-permeable geosynthetic.Geotextile yog ib qho ntawm cov khoom siv tshiab geosynthetic, cov khoom tiav yog daim ntaub, dav dav yog 4-6 meters, qhov ntev yog 50-100 meters.Staple fiber needled nonwoven geotextiles muab faib ua polyester, polypropylene fiber, nylon, vinylon, ethylene fiber thiab lwm yam nonwoven geotextiles raws li raw cov ntaub ntawv.Cov yam ntxwv.ntawm geosynthetic yog dej permeability, corrosion kuj, hnav tsis kam, siab tensile zog, laus kuj thiab lwm yam.Geotextile yog ib hom geotechnical khoom siv dav hauv kev tsim kho txoj kev, reservoirs, tunnels, DAMS thiab lwm yam.Nws lub luag haujlwm tseem ceeb yog kev sib cais, pom, kua dej, ruaj khov thiab txhawb nqa.Vim nws txoj kev siv dav thiab qhov tseem ceeb, lub zog tensile, tawg lub zog, permeability thiab ntaub hnyav thiab lwm yam khoom yog qhov xav tau siab heev.Lub hnub qub koob ntawm Hengxiang koob yog qhov tsim nyog tshaj plaws rau kev tsim cov khoom muaj zog geotextile, tshwj xeeb tshaj yog rau kev tsim cov staple fiber ntau thiab spinning av nplaum daim ntaub yog pom tseeb dua.Lub hnub qub-zoo li tus koob ntawm plaub-sided nuv spines enables ib tug siab entanglement tus nqi thiab txo cov kev puas tsuaj rau cov fibers.Muaj ntau ntau hom fibers siv los tsim geotextiles, nyob ntawm seb daim ntawv thov tshwj xeeb.Feem ntau yog polyester, polypropylene, thiab nylon.Lub thickness ntawm fiber ntau yog nyob nruab nrab ntawm 4 thiab 10 danels, nrog rau qee cov khoom siv cov fiber ntau thicker.Qhov tob tob yog feem ntau 10 mus rau 12 hli, thiab qhov tob tob yog feem ntau 100 mus rau 400 koob ib C square meters.Spinning av nplaum daim ntaub feem ntau xav tau ib tug high-speed needling tshuab nrog ib tug ceev ntawm 2000 mus rau 3000 pos ib feeb, thiab lub needling ceev kuj tsawg.Feem ntau lub tshuab tseem ceeb yog 100 mus rau 300 pos ib C square metres, thiab qhov pom zoo xav tau qhov tob yog 10 mus rau 12 hli.
