Qhov Tseem Ceeb Qhov txawv - Olefin vs Polypropylene
Olifin thiab polypropylene yog ob qib kev lag luam fibers uas tau siv dav rau ntau yam kev siv. Polypropylene fibers yog tsim los ntawm propylene molecules whereas olefin fibers yuav ua tau siv olefin molecules xws li ethylene thiab propylene. Qhov no yog qhov sib txawv tseem ceeb ntawm Olefin thiab Polypropylene.
Olefin yog dab tsi?
Olefin yog cov khoom siv hluavtaws ua los ntawm polyolefin molecules xws li polypropylene lossis polyethylene. Nws yog siv los tsim cov ntawv ntsa, ntaub pua plag, tsheb sab hauv, tiv thaiv khaub ncaws thiab hlua. Olefin muaj qee qhov kev cog lus zoo xws li lub zog, xim nrawm, thiab kev nplij siab. Tsis tas li ntawd, nws yog resistant rau abrasion, staining tshav ntuj, acids, fungi, thiab mildew. Olefin fibers degrade qeeb nyob rau hauv tshav ntuj thiab stain los ntawm roj.
YPolypropylene yog dab tsi?
Polypropylene (PP) lossis polypropene yog cov thermoplastic polymer uas yog tsim los ntawm polymerization ntawm propylene. Nws muaj ntau hom kev lag luam xws li ntim khoom, sau npe, tsim cov khoom yas, cov thawv rov qab siv tau, cov khoom siv kuaj, cov khoom siv tsheb, cov hais lus nrov, thiab cov ntawv sau. Nws yog resistant rau ntau yam tshuaj thiab yog rugged nyob rau hauv cov xwm. Tsis tas li ntawd, nws muaj qhov ntog heev uas tsis tso cai rau nws los koom nrog cov kua nplaum txaus. Cov txheej txheem vuam feem ntau yog siv los koom nrog cov ntaub ntawv polypropylene.
Qhov txawv ntawm Olefin thiab Polypropylene yog dab tsi?
qauv:
Olefin: Olefin fibers tuaj yeem muaj ntau lub qauv molecular vim ntau hom molecules tuaj yeem siv los tsim lawv. Piv txwv li; ethylene, propylene los yog lwm yam olefins. Ob hom polymers yog siv nyob rau hauv olefin fibers. Thawj, polyethylene, yog ib qho yooj yim linear qauv nrog rov qab units. Cov fibers no feem ntau yog siv rau cov hlua, twines, thiab cov ntaub siv hluav taws xob. Hom thib ob, polypropylene, yog cov qauv peb-dimensional nrog lub nraub qaum ntawm carbon atoms.
Polypropylene: Polypropylene yog tsim los ntawm polymerization ntawm propylene molecules.
Siv:
Olefin: Olefin tau siv ntau thaj chaw rau ntau yam kev siv hauv kev lag luam. Hauv kev lag luam khaub ncaws, nws yog siv hauv activewear, sportswear (socks) thiab thermal underwear (lining fabrics). Nws kuj tseem siv rau hauv cov khoom siv tsheb hauv qee yam khoom siv; Piv txwv li, cov khoom siv sab hauv siv los yog hauv cov khoom siv ncaws pob, pob tawb, lub rooj tsim kho, cov tsheb thauj khoom thiab cov khoom thauj khoom. Ntxiv mus, nws yog siv nyob rau hauv cov khoom vaj khoom tsev; Cov ntaub pua plag hauv tsev thiab sab nraum zoov, ntaub pua plag rov qab, phab ntsa npog thiab hauv rooj tog.
Polypropylene: Polypropylene tuaj yeem siv rau hauv ntim, sau npe, tsim cov khoom yas, cov thawv rov qab siv tau, cov khoom siv hauv tsev, cov khoom siv tsheb, lub suab nrov, thiab cov ntawv sau.
Properties:
Olefin: Olefin yog ib qho muaj zog, hnav, hnav tsis kam, thermally bondable thiab xis nyob. Nws kuj yog resistant rau tshav ntuj, av thiab staining. Olefin yog resistant rau deterioration ntawm tshuaj, perspiration, mildew, rot thiab huab cua. Nws kuj muaj cov khoom kom qhuav sai thiab muaj peev xwm muab cov khoom zoo thiab npog.
Tshwj xeeb, cov stains ntawm cov ntaub olefin tuaj yeem raug tshem tawm yooj yim los ntawm kev pom nrog dej sov thiab tshuaj ntxuav tes. Bleaches kuj siv tau yog tias xav tau. Cov ntaub no tuaj yeem ntxhua khaub ncaws thiab nws yuav tsum tau muab cov kab ziab los yog ziab nrog cov cua sov los yog tsis muaj cua sov tom qab ntxhua khaub ncaws. Olefin dries sai heev.
Polypropylene: Feem ntau, polypropylene yog cov khoom siv tau yooj yim, tsis tshua muaj ntom thiab tawv. Feem ntau ntawm cov khoom ntawm polypropylene zoo ib yam li polyethylene. Nws muaj ib pab pawg methyl ntxiv uas txhim kho cov neeg kho tshuab thiab thermal tsis kam tab sis txo cov tshuaj tiv thaiv. Polypropylene tiv taus cov rog thiab tag nrho cov tshuaj organic feem ntau, tshwj tsis yog cov oxidants muaj zog ntawm chav tsev kub.
