Cov iav fiber ntau yog ib yam ntawm cov khoom siv tsis zoo uas tsis yog xim hlau nrog kev ua haujlwm zoo.Nws muaj ntau yam.Nws qhov zoo yog rwb thaiv tsev zoo, muaj zog tiv thaiv tshav kub, zoo corrosion kuj thiab siab mechanical zog, tab sis nws qhov tsis zoo yog brittleness thiab hnav tsis zoo.Nws yog ua los ntawm cov iav pob lossis cov iav khib nyiab los ntawm kev kub kub melting, kos duab, winding, weaving thiab lwm yam txheej txheem.Txoj kab uas hla ntawm nws cov monofilament yog los ntawm ob peb microns mus rau 20 microns.Txhua pob ntawm fiber ntau precursor yog tsim los ntawm ntau pua lossis ntau txhiab tus monofilaments.Cov iav fiber ntau feem ntau yog siv los ntxiv dag zog hauv cov khoom sib xyaw, cov khoom siv hluav taws xob rwb thaiv tsev thiab cov ntaub ntawv thermal rwb thaiv tsev, cov khoom siv hluav taws xob thiab lwm yam kev lag luam hauv lub tebchaws.Cov iav fiber ntau muaj qhov kub thiab txias dua li cov organic fiber ntau, tsis tuaj yeem tawg, corrosion kuj, zoo rwb thaiv tsev thiab suab rwb thaiv tsev, siab tensile zog thiab zoo hluav taws xob rwb thaiv tsev.Tab sis nws yog nkig thiab muaj kev hnav tsis zoo.Siv los ua cov yas muaj zog (saib daim duab xim) lossis cov roj hmab ntxiv, ua cov khoom siv ntxiv, iav fiber ntau muaj cov yam ntxwv hauv qab no, uas ua rau kev siv cov iav fiber ntau ntau dua li lwm hom fibers.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 muaj pes tsawg leeg, nws tuaj yeem muab faib ua alkali dawb, tshuaj tiv thaiv, siab alkali, nruab nrab alkali, siab zog, siab elastic modulus thiab alkali resistant iav fiber.
