1. Polypropylene Fiber yog dab tsi?
Polypropylene fiber, tseem hu ua polypropylene fiber, yog ib tug hluavtaws fiber spun los ntawm isotactic polypropylene, tau los ntawm polymerizing propylene.
Polypropylene fibers tuaj yeem muab faib ua cov fibers ntev, luv fibers, spunbond non-woven fabrics, meltblown non-woven fabrics, thiab lwm yam.
Polypropylene ntev fibers tuaj yeem muab faib ua cov fibers ntev ntev thiab nplua denier ntev fibers (monofilament fineness Tsawg dua los yog sib npaug rau 2.2 dtex, siv los tsim cov khaub ncaws, kho kom zoo nkauj, thiab qee cov khoom siv filament). Fine denier polypropylene ntev fibers muaj luster zoo, mos tes xav, zoo drape, thiab tsawg ntom, ua rau lawv haum rau knitting kev lag luam. Thaum interwoven nrog paj rwb, viscose filament, txhob lo lo ntxhuav, spandex, thiab lwm yam., los ua paj rwb-polypropylene thiab txhob lo lo ntxhuav-cov khoom siv polypropylene, lawv yog cov khoom siv zoo tshaj plaws rau kev ua siab -kawg sportswear, T-shirts, thiab lwm yam.
Cov txheej txheem ntau lawm ntawm polypropylene luv fibers feem ntau txais cov ntxeem tau, qis - nrawm, txheej txheem txuas ntxiv, piv txwv li, luv - spinning. Polypropylene luv fibers sib xyaw nrog paj rwb tuaj yeem ua rau hauv polypropylene- paj rwb ntaub thiab ntaub pua txaj; blended fibers nrog viscose tuaj yeem ua rau hauv daim pam; ntshiab thiab sib xyaw polypropylene yarns, polypropylene pam, ntaub pua plag, thiab polypropylene paj rwb wadding rau luam yeeb lim. Cov fiber ntau zoo rau cov khoom siv tu cev yog 1.5-2.5 dtex, thaum fiber ntau zoo rau hauv pem teb fabrics yog 5-10 dtex. Fiber ntev li ntawm 1.5 mus rau 200.0 hli. Qhov ntev ntawm cov fiber ntau txawv nyob ntawm seb nws xav siv. Cov fibers luv luv siv hauv pob zeb ntau yam ntawm 1.5 txog 200.0 hli, thaum cov siv hauv av npog thaj tsam ntawm 60.0 hli.
2. Cov yam ntxwv ntawm Polypropylene Fibers
(1) Lub teeb hnyav.Qhov ceev ntawm polypropylene fibers yog 0.90-0.92. Polypropylene muaj qhov qis tshaj g / cm3 cov ntsiab lus ntawm tag nrho cov tshuaj fibers, yog 20% sib zog dua nylon, 30% sib zog dua polyester, thiab 40% sib zog tshaj viscose fiber. Yog li ntawd, nws yog qhov zoo rau siv los ua cov khoom ntim rau lub caij ntuj no khaub ncaws los yog ntaub rau caij ski suits, mountaineering suits, thiab lwm yam.
(2) Lub zog muaj zog, zoo elasticity, hnav tsis kam, thiab corrosion kuj.Polypropylene muaj lub zog siab (ob qho tib si qhuav thiab ntub dej), ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev tsim nuv ntses nets thiab hlua; nws muaj kev hnav zoo thiab ua haujlwm zoo, nrog lub zog zoo ib yam li polyester thiab nylon, thiab tus nqi resilience piv rau nylon thiab ntaub plaub, ntau dua polyester thiab viscose fiber ntau; polypropylene muaj qhov tsis zoo ntawm qhov ruaj khov, nws yooj yim rau pilling thiab deformation, tiv taus cov kab mob thiab npauj; thiab muaj tshuaj tiv thaiv zoo dua li cov fibers dav dav.
(3) Nws muaj hluav taws xob rwb thaiv tsev thiab ua kom sov so.Polypropylene fiber ntau muaj qhov tiv taus siab heev (7 × 10¹⁹ Ω·cm) thiab thermal conductivity tsawg. Piv nrog rau lwm cov tshuaj fibers, polypropylene muaj qhov zoo tshaj plaws hluav taws xob rwb thaiv tsev thiab sov so lub zog, tab sis nws yog nquag siv hluav taws xob zoo li qub thaum ua.
(4) Cov cua sov tsis zoo thiab kev laus ua haujlwm.Polypropylene fiber ntau muaj qhov melting point tsawg. (165 ~ 173 degree) Polypropylene muaj kev ruaj ntseg tsis zoo rau lub teeb thiab cua sov, ua rau cov cua sov tsis zoo, tiv thaiv kev laus, thiab tsis muaj hlau tsis zoo. Txawm li cas los xij, nws cov khoom tiv thaiv - kev laus tuaj yeem txhim kho los ntawm kev ntxiv cov tshuaj tiv thaiv - kev laus thaum lub sij hawm tig.
(5) Tsis zoo hygroscopicity thiab dyeability.Polypropylene fiber ntau muaj qhov phem hygroscopicity thiab dyeability ntawm cov tshuaj fibers, yuav luag tsis muaj noo noo nqus, thiab nws cov dej noo rov qab yog tsawg dua 0.03%. Fine denier polypropylene muaj cov nyhuv wicking muaj zog, tso cai rau cov dej noo kom raug tshem tawm los ntawm cov capillaries hauv fiber ntau. Thaum ua rau hauv cov khaub ncaws, cov khaub ncaws hnav zoo dua, tshwj xeeb tshaj yog nrog ultrafine polypropylene fiber ntau, uas, vim nws qhov chaw nce ntxiv, tuaj yeem hloov tawm hws sai dua, ua kom cov tawv nqaij xis nyob. Vim tias cov fiber ntau tsis nqus dej noo thiab muaj qhov qis qis, cov ntaub ntawv polypropylene yooj yim los ntxuav thiab ceev - ziab.
Polypropylene muaj dyeability tsis zoo, uas ua rau lub teeb xim thiab tsis zoo xim ceev ceev. Ordinary dyes tsis tuaj yeem zas nws, thiab cov xim polypropylene feem ntau yog tsim los ntawm pre-spinning dyeing. Kev daws teeb meem dyeing thiab hloov kho fiber ntau tuaj yeem siv, nrog cov dye complexing agents ntxiv ua ntej yaj.
