Raws li cov duab thiab ntev, iav fiber ntau tuaj yeem muab faib ua fiber ntau txuas ntxiv, ruaj khov ntev fiber ntau thiab iav ntaub plaub. Raws li cov iav tivthaiv, nws tuaj yeem muab faib ua alkali-dawb, tshuaj-resistant, high-alkali, nruab nrab-alkali, siab-lub zog, high-elasticity modulus thiab alkali-resistant iav. Fiber, thiab lwm yam.
Cov iav fiber ntau tau muab faib ua ntau qib raws li muaj pes tsawg leeg, xwm thiab siv. Raws li tus qauv qib, E-chav kawm iav fiber ntau yog feem ntau siv thiab dav siv hauv cov khoom siv hluav taws xob rwb thaiv tsev. S qib yog tshwj xeeb fiber. Txawm hais tias cov zis yog me me, nws tseem ceeb heev. Nrog lub zog super, feem ntau yog siv rau kev tiv thaiv tub rog, xws li lub thawv tsis muaj phom; Class C yog cov tshuaj tiv thaiv ntau dua li Class E, siv rau cov roj teeb cais, cov tshuaj lim dej; Class A yog alkaline iav fiber ntau, siv los tsim cov khoom siv ntxiv.
