Ukuthuthukiswa kokuqala kanye nokusetshenziswa kwe-polypropylene fiber kwaqala ngo-1960s.Uma kuqhathaniswa neminye imicu yokwenziwa evamile nesetshenziswa kabanzi njenge-polyester fibre ne-acrylic fibre, ukuthuthukiswa nokusetshenziswa kwe-polypropylene fiber kuqale sekudlule isikhathi uma kuqhathaniswa.Ngesikhathi esifanayo, ngenxa yokukhishwa kwayo okuncane nokusetshenziswa kwayo, ukusetshenziswa kwayo kwakungebanzi kakhulu ekuqaleni.Njengamanje, ngokusungulwa okusha okuqhubekayo kwesayensi nobuchwepheshe, ucwaningo oluqhubekayo nokuthuthukiswa kanye nokuthuthukiswa kwezinto ezintsha zendwangu, izinqubo ezintsha nobuchwepheshe obusha, ucwaningo nokuthuthukiswa nokukhiqizwa kwe-polypropylene fiber kancane kancane kunakwa futhi isetshenziswa, ikakhulukazi ezikhathini zamuva nje. iminyaka engamashumi amabili, isivinini sokukhula kwayo siyashesha, futhi kancane kancane sekuyifayibha entsha ethandwa kakhulu emkhakheni wezindwangu.
I-polypropylene fiber yigama lokuhweba le-polypropylene fiber, futhi iyi-polymer ephezulu eyenziwe nge-propylene njenge-monomer.Kuyi-molecule engeyona i-polar.I-polypropylene fiber ine-gravity ethize ekhanyayo engu-0.91, engu-3/5 kakotini ne-viscose fiber, 2/3 we-wool ne-polyester fiber, kanye no-4/5 we-acrylic fiber ne-nylon fiber.Inamandla amakhulu, amandla e-fiber eyodwa angu-4.4 ~ 5.28CN/dtex, ukubuyiswa komswakama ophansi, ukumuncwa okuncane kwamanzi, ngokuyisisekelo amandla afanayo amanzi kanye namandla omile, kanye ne-wicking enhle, ukumelana nokugqoka okuhle nokuqina.Kodwa-ke, kusukela ekuhlaziyweni kwesakhiwo sayo se-macromolecular, ukuzinza kwayo ekukhanyeni nasekushiseni akulungile, kulula ukuguga, futhi indawo yayo yokuthambisa iphansi (140℃-150℃).Ngesikhathi esifanayo, ukwakheka kwawo kwamangqamuzana akunawo amaqembu ahambisana nama- molecule kadayi, ngakho ukusebenza kwawo kokudaya akulungile.(Okwamanje, emthonjeni wokuphotha wemicu, izinhlobo ezihlukahlukene zemicu ye-polypropylene ekhanyayo zingenziwa ngokungeza i-masterbatch yombala.)
