Ib qho: Qhov ntom ntawm lub teeb yuag polypropylene fiber ntau yog 0.90-0.92 g / cm3, uas yog lub teeb ntawm tag nrho cov tshuaj fibers. Nws yog 20% sib dua li nylon, 30% sib zog dua polyester, thiab 40% sib zog dua viscose fiber. Yog li ntawd, nws yog qhov tsim nyog los siv los ua cov khoom siv rau lub caij ntuj no khaub ncaws lossis ntaub rau caij ski suits thiab mountaineering suits.
Ob: Lub zog muaj zog, zoo elasticity, hnav tsis kam thiab corrosion kuj:
Polypropylene muaj lub zog siab (zoo ib yam nyob rau hauv qhuav thiab ntub dej), thiab yog ib qho khoom siv zoo tshaj plaws rau kev ua nuv ntses nets thiab cables; Nws muaj kev ua kom zoo thiab ua haujlwm zoo, nws lub zog zoo ib yam li polyester thiab nylon, thiab nws cov nyiaj rov qab yog piv rau nylon thiab ntaub plaub. Qiv thiab viscose fibers yog loj dua; polypropylene fiber muaj qhov tsis zoo ntawm qhov ruaj khov, yooj yim rau pilling thiab deformed, tiv thaiv kab mob, thiab tsis npauj; tshuaj tiv thaiv zoo dua li cov fibers zoo tib yam.
Peb: Nws muaj hluav taws xob rwb thaiv tsev thiab sov so tuav:
Polypropylene fiber ntau muaj hluav taws xob tiv taus (7 × 1019Ω.cm) thiab thermal conductivity tsawg. Piv nrog rau lwm cov tshuaj fibers, polypropylene fiber ntau muaj hluav taws xob rwb thaiv tsev zoo heev thiab sov so, tab sis nws yooj yim los tsim hluav taws xob zoo li qub thaum ua.
Plaub: Tsis zoo kub tsis kam thiab kev laus ua haujlwm:
Polypropylene fiber ntau muaj qhov melting point (165 ~ 173 ° C) thiab tsis zoo stability rau lub teeb thiab cua sov. Yog li ntawd, polypropylene fiber ntau muaj cov cua sov tsis zoo thiab kev laus ua haujlwm, thiab tsis tiv taus ironing. Tab sis nws tuaj yeem txhim kho nws qhov kev tiv thaiv kev laus los ntawm kev ntxiv cov tshuaj tiv thaiv kev laus thaum lub sij hawm spinning.
Tsib: Tsis zoo hygroscopicity thiab dyeability:
Lub hygroscopicity thiab dyeability ntawm polypropylene fibers yog cov tsis zoo ntawm cov tshuaj fibers, yuav luag tsis muaj noo noo nqus, thiab nws cov noo noo regain tus nqi yog tsawg tshaj li 0.03%. Fine denier polypropylene muaj cov nyhuv wicking muaj zog, thiab dej vapor tuaj yeem raug tshem tawm los ntawm capillary hauv fiber ntau. Tom qab ua rau hauv cov khaub ncaws, qhov kev nplij siab ntawm cov khaub ncaws zoo dua, tshwj xeeb tshaj yog cov fiber ntau polypropylene, vim tias qhov chaw ntawm qhov chaw nce, tuaj yeem xa hws sai dua thiab ua kom cov tawv nqaij xis nyob. Vim tias cov fiber ntau tsis nqus dej noo thiab muaj qhov me me me, cov ntaub polypropylene muaj cov yam ntxwv ntawm kev ntxuav yooj yim thiab ziab sai.
Polypropylene muaj dyeability tsis zoo, lub teeb xim, thiab tsis zoo dye fastness. Cov roj qub qub tsis tuaj yeem dyed, thiab feem ntau ntawm cov xim polypropylene fibers yog tsim los ntawm cov xim ua ntej spinning. Nws tuaj yeem siv rau xim, hloov kho fiber ntau, thiab sib xyaw nrog cov roj complexing tus neeg sawv cev ua ntej yaj.
