Qhov zoo thiab tsis zoo los ntawm olefin ntaub
Olefin ntaub hais txog ntawm cov hluavtaws hluavtaws sib xyaw ua ke ntawm cov kab tawm macromolecules polymerized los ntawm olefins. Olefin yog ib tug txiv neej-ua fiber ntau uas nws cov fiber ntau tsim yog qhov ntev-cov xov hluavtaws polymer. Cov polymer no yog tsim tsawg kawg 85% los ntawm qhov hnyav ntawm ethylene, propylene lossis lwm yam olefin monomers, tab sis nws yog amorphous (tsis-crystalline) Tshwj tsis yog polyolefins ntawm cov roj hmab fibers, olefin cov ntaub muaj cov pas nrig zoo li tus qauv nrog du nto.
Olefin npuag yog lub teeb muaj fiber ntau nrog lub zog zoo thiab zoo hnav tsis kam. Cov fiber no tseem muaj cov tiv taus tiv tshav ntuj thiab huab cua. Olefin npuag yog yuav luag tag nrho cov hydrophobic (noo noo tsuas yog 0. 1), stains tuaj yeem tshem tawm tau yooj yim, ua rau cov tshuaj fiber no siv tau rau hauv cov ntaub pua tsev sab hauv / sab nraum zoov, chav dej thiab chav ua noj pua rooj tog thiab kho kom zoo nkauj sab hauv. Olefin cov ntaub tuaj yeem muab ntxuav thiab qhuav ntxuav kom huv. Txawm hais tias cov fiber no yog cov ntawv ua kua hydrophobic, nws muaj cov plaub hau zoo thaum nws yuag heev, thiab tib lub sij hawm, nws muaj cov khoom zoo ua tau zoo.
Vim tias cov khoom siv fiber no yuav luag muaj cov khoom siv hydrophobic, nws tsis zoo rau kev tsim cov khaub ncaws feem ntau. Thaum olefin ntaub yog sib xyaw nrog lwm cov ntaub, nws cov hydrophobicity thiab ntaub plaub ua rau nws haum rau cov khaub ncaws ua kis las thiab lwm yam kev ua haujlwm siab siv qhov tseeb ntawm cov ntaub. Olefin cov ntaub qhwv qee zaum tsim hluav taws xob zoo nkauj thiab pilling. Nws yuav tsum tau muab ironed, siv lub tshuab ntxuav thiab ziab ntawm qhov kub tsis tshua muaj (txog 150 ° F, piv txwv li 65 ° C) vim tias qhov muag muag ntawm cov fiber no tsawg heev.
