Olefin kev faib tawm ntaub
Olefin cov ntaub muaj cov ntaub thaiv tsis zoo, yog li cov kev siv tseem ceeb ntawm cov khaub ncaws yog cov kis las, gymnastics hnav thiab ris tsho hauv qab, thiab siv tseem ceeb yog cov ntaub tsis-ntaub thiab xov paj siv rau cov ntaub pua plag. Olefin cov npuag kuj tseem siv tau cov ntaub ua kom zoo nkauj, ntaub npuag kev lag luam (xws li cov phuam qhwv ntaub, hnab ntim khoom ntim) thiab geotextiles.
Olefin cov ntaub tuaj yeem muab faib ua cov fiber ntau ntev, luv luv fiber ntau, spunbond nonwoven npuag, meltblown nonwoven npuag, thiab lwm yam.
Olefin ntev fiber ntau tau muab faib ua cov plaub hau ntev uas zoo tib yam thiab cov nplua zoo ntawm cov plaub hau ntev (monofilament fineness ≤ 2. 2 dtex, uas tuaj yeem siv hauv kev tsim cov khaub ncaws thiab kho kom zoo nkauj thiab qee cov khoom lag luam ua tau zoo. zoo denier ntev cov xov paj tau zoo gloss, mos hnov thiab zoo drape., ntom ntuag, haum rau kev lag luam knitting, thaum sib xyaw nrog paj rwb, xov paj viscose, silk, spandex, thiab lwm yam rau hauv paj rwb npog acrylic, silk npog acrylic thiab lwm yam khoom, nws yog cov khoom siv zoo tshaj plaws rau kev ua cov kis las siab, T-shirts thiab lwm yam.
Feem ntau ntawm cov txheej txheem ntau lawm ntawm olefin staple fiber adopts ntxeem tau, ua kom qis-nrawm, txuas ntxiv cov txheej txheem, uas yog txoj kev luv luv spinning. Olefin luv luv fiber ntau ua ke nrog paj rwb tuaj yeem ua rau polypropylene paj rwb ntaub thiab cov ntawv, uas yog, fiber ntau thiab viscose blended tuaj yeem siv ua cov pam vov, olefin ntshiab thiab cov xov paj sib xyaw, olefin pam, ntaub pua av, thiab olefin paj rwb fume luam yeeb lim. Lub tuab ntawm cov fiber ntau rau cov khoom siv huv yog 1 .5-2. 5 dtex, thiab tuab ntawm cov fiber ntau rau cov ntaub hauv av yog 5-10 dtex. Cov duab fiber ntev yog 1 .5-200.0 hli, nyob ntawm kev siv cov khoom siv fiber ntau. Cov xov paj ntev ntev siv rau pob zeb ua haujlwm yog 1. 5-200.0 hli, qhov ntev siv rau cov pawm ntau yog feem ntau 40 .0 hli, thiab qhov ntev siv rau cov ntaub pua plag yog 60. 0 hli.
Spunbond tsis-ntaub npuag, tseem hu ua filament non-woven npuag, yog tsim los ntawm melting olefin raw khoom los ntawm extrusion spinning, ncab, mesh txheej, thiab cov nplaum ua. Nws muaj cov yam ntxwv ntawm kev ua luv luv, tsis tshua muaj nqi, khoom lag luam siab, kev ua tau zoo khoom thiab kev siv ntau yam. Olefin non-woven fabrics yog siv dav hauv ntau qhov chaw ntawm kev tsim khoom thiab lub neej (xws li cov khoom siv kho mob pov tseg thiab kev noj qab haus huv, pov tseg cov khaub ncaws tsis huv, khoom siv ua liaj ua teb, rooj tog ntaub, khau ntaub, thiab lwm yam).
Cov fibers tsim los ntawm cov yaj tshuab cov tshuab tsis-woven cov ntaub ua tau zoo heev (txog 0. 25 μm). Cov ntaub npuag yaj tau qhov tshwj xeeb ib cheeb tsam chaw, me me hws thiab cov porosity loj, yog li nws cov filterability, shielding zog thiab cov roj nqus cov khoom siv tau siv. Cov xov uas tsis-tsim los ntawm lwm cov txheej txheem sib cais yog qhov nyuaj rau muaj. Melt-blown non-woven fabrics yog dav siv hauv kev kho mob thiab kev noj qab haus huv, khoom siv rwb thaiv tsev thermal, cov ntaub ntawv lim dej thiab lwm cov teb.
