Qhov ntxov tshaj plaws kev loj hlob thiab kev siv ntawm polypropylene fiber ntau pib nyob rau hauv 1960s.Piv nrog rau lwm yam thiab dav siv hluavtaws fibers xws li polyester fiber thiab acrylic fiber, txoj kev loj hlob thiab kev siv ntawm polypropylene fibers pib lig.Nyob rau tib lub sijhawm, vim nws cov khoom siv me me thiab siv tau, nws daim ntawv thov tsis yog qhov dav heev nyob rau theem pib.Tam sim no, nrog kev nruam ntej ntawm kev tshawb fawb thiab thev naus laus zis, kev tshawb fawb txuas ntxiv thiab kev tsim kho thiab kho dua tshiab ntawm cov ntaub ntawv textile, cov txheej txheem tshiab thiab cov thev naus laus zis tshiab, kev tshawb fawb thiab kev tsim kho thiab tsim cov polypropylene fiber ntau tau maj mam them nyiaj rau thiab siv, tshwj xeeb tshaj yog nyob rau hauv tsis ntev los no. nees nkaum xyoo, nws txoj kev loj hlob sai, thiab nws tau maj mam dhau los ua ib qho tshiab fiber ntau hauv textile teb.
Polypropylene fiber yog lub npe lag luam ntawm polypropylene fiber ntau, thiab nws yog ib lub siab polymerized nrog propylene li monomer.Nws yog ib qho tsis-polar molecule.Polypropylene fiber muaj lub teeb tshwj xeeb lub ntiajteb txawj nqus ntawm 0.91, uas yog 3/5 ntawm paj rwb thiab viscose fiber, 2/3 ntawm ntaub plaub thiab polyester fiber, thiab 4/5 ntawm acrylic fiber thiab nylon fiber.Nws muaj lub zog siab, ib lub zog fiber ntau ntawm 4.4 ~ 5.28CN / dtex, tsis tshua muaj ya raws, kev nqus dej me me, qhov tseem ceeb tib lub zog ntub thiab qhuav lub zog, thiab zoo wicking, zoo hnav tsis kam thiab resilience.Txawm li cas los xij, los ntawm kev soj ntsuam ntawm nws cov qauv macromolecular, nws qhov ruaj khov rau lub teeb thiab cua sov yog qhov tsis zoo, nws yooj yim rau hnub nyoog, thiab nws qhov muag muag yog qis (140 ℃ - 150 ℃).Nyob rau tib lub sijhawm, nws cov qauv molecular tsis muaj pab pawg uas sib haum nrog dye molecules, yog li nws cov dyeing kev ua haujlwm tsis zoo.(Tam sim no, ntawm spinning qhov chaw ntawm fibers, ntau hom ci polypropylene fibers tuaj yeem tsim los ntawm kev ntxiv xim masterbatch.)
