- Cov cuab yeej zoo heev. Qee qhov kev ntsuas hauv tsev pom tau tias lub zog tensile yog 1.5-1.9 npaug ntawm qhov hnyav sib xws gram stapled koob-punched nonwoven geotextile. Qee cov ntaub ntawv txawv teb chaws qhia tau hais tias qhov sib txawv txawm tias loj dua. Lub zog thiab nkag khoom xws li kua muag thiab tawg yog tseem zoo dua cov ntawm cov luv luv-fiber koob-punched geotextiles.
- Qhov kev ua tau zoo hydraulic yog qhov sib npaug li cov staple fiber needled geotextile, thiab cov permeability coefficient yog tib qho kev txiav txim ntawm qhov ntau vim cov staple fiber needled geotextile. Raws li ntev raws li nws tau siv kom zoo, permeability coefficient tuaj yeem ruaj khov tom qab ib ntus, thiab cov av seem tsis ploj nrog dej ntws.
- Lub tshuab kiv nrawm nrawm, lub tshuab tso tawm ib zaug yog ntau dua li cov cuab yeej siv luv fiber ntau
