Polyester, iav Fiber, Tshuaj Fibers, thiab lwm yam.
Polyester yog ntau hom hluavtaws fiber ntau thiab ua lub npe lag luam rau polyester fiber hauv kuv lub tebchaws. Nws yog fiber ntau-forming polymer-tshwj xeeb polyethylene terephthalate (PET)- tsim los ntawm esterification (los yog transesterification) thiab cov tshuaj tiv thaiv polycondensation, siv purified terephthalic acid (PTA) los yog dimethyl terephthalate (DMT) thiab ethylene glycol (EG) raw cov ntaub ntawv.
Cov iav fiber ntau yog ib qho inorganic, tsis yog -cov khoom siv hlau uas muaj cov khoom zoo heev thiab yog ib feem tseem ceeb ntawm cov iav fiber ntau. Nws lub npe lus Askiv yog "iav fiber ntau." Nws muaj pes tsawg leeg feem ntau suav nrog silicon dioxide, aluminium oxide, calcium oxide, boron oxide, magnesium oxide, sodium oxide, thiab lwm yam. Nws yog tsim los ntawm cov iav hlaws los yog cov iav siv dua tshiab ua cov khoom siv raw, ua tiav los ntawm ntau cov kauj ruam suav nrog siab - kub melting, kos duab, winding, thiab weaving. Qhov kawg tso zis muaj xws li ntau yam khoom siv; txoj kab uas hla ntawm ib lub iav fiber ntau filament feem ntau yog nyob ntawm ob peb microns mus rau ntau dua nees nkaum microns- sib npaug li kwv yees li 1/20 txog 1/5 lub thickness ntawm tib neeg cov plaub hau. Txhua pob ntawm cov fibers nyoos muaj ntau pua lossis ntau txhiab tus neeg filaments. Cov iav fiber ntau feem ntau yog siv los ua cov khoom siv txhawb zog hauv cov khoom sib xyaw, xws li hluav taws xob rwb thaiv tsev, thermal rwb thaiv tsev, thiab hauv Circuit Court board substrates, nrhiav kev siv dav thoob plaws ntau lub teb chaws kev lag luam.
Cov tshuaj fibers yog cov fibers uas tsim los siv cov khoom siv ntuj tsim los yog cov khoom siv hluavtaws ua cov khoom siv raw. Raws li lub hauv paus chiv keeb ntawm cov ntaub ntawv raw, cov tshuaj fibers tuaj yeem muab faib ua ob pawg: "regenerated fibers" (los yog cov khoom siv fiber ntau), uas tau muab los ntawm cov khoom siv ntuj tsim, thiab "synthetic fibers," uas tau muab los ntawm cov khoom siv hluavtaws polymeric.
