Uphuhliso lokuqala kunye nokusetyenziswa kwe-polypropylene fiber kwaqala ngo-1960s.Xa kuthelekiswa nezinye iintsinga zokwenziwa eziqhelekileyo nezisetyenziswa ngokubanzi ezifana nefiber yepolyester kunye ne-acrylic, uphuhliso kunye nokusetyenziswa kwefiber yepolypropylene kuqale kade noko.Ngexesha elifanayo, ngenxa yemveliso encinci kunye nokusetyenziswa kwayo, isicelo sayo sasingekho kakhulu kwinqanaba lokuqala.Okwangoku, ngokuqhubeka ngokutsha kwesayensi kunye nethekhinoloji, uphando oluqhubekayo kunye nophuhliso kunye nophuculo lwemathiriyeli entsha yelaphu, iinkqubo ezintsha kunye nobuchwepheshe obutsha, uphando kunye nophuhliso kunye nokuveliswa kwefayibha ye-polypropylene ngokuthe ngcembe inikwa ingqalelo kwaye isetyenziswa, ngakumbi kutsha nje. iminyaka engamashumi amabini, isantya sayo sophuhliso siyakhawuleza, kwaye ngokuthe ngcembe iye yaba yifayibha entsha ethandwa kakhulu kwindawo yelaphu.
Ifayibha yePolypropylene ligama lokurhweba le-polypropylene fiber, kwaye yipolymer ephezulu eyenziwe nge-propylene njenge-monomer.Yimolekyuli engeyiyo ipolar.Ifayibha yePolypropylene inomxhuzulane ocacileyo we-0.91, eyi-3/5 ye-cotton kunye ne-viscose fiber, i-2/3 yoboya kunye ne-polyester fiber, kunye ne-4/5 ye-acrylic fiber kunye ne-nylon fiber.Inamandla amakhulu, amandla e-fiber enye ye-4.4 ~ 5.28CN / dtex, ukubuyiswa komswakama ophantsi, ukufunxwa kwamanzi amancinci, ngokusisiseko amandla afanayo amanzi kunye namandla omileyo, kunye ne-wicking efanelekileyo, ukuxhathisa okulungileyo kunye nokuqina.Nangona kunjalo, ukusuka kuhlalutyo lwesakhiwo sayo se-macromolecular, ukuzinza kwayo ekukhanyeni kunye nokushisa akubi, kulula ukuguga, kwaye indawo yayo yokuthambisa iphantsi (140 ℃-150 ℃).Kwangaxeshanye, imolekyuli yayo ayinamaqela ahambelana neemolekyuli zedayi, ngoko ke ukusebenza kwayo kokudaya kumbi.(Okwangoku, kumthombo ojikelezayo weentsinga, iintlobo ezahlukeneyo zeentsinga zepolypropylene eziqaqambileyo zinokwenziwa ngokongeza i-masterbatch yombala.)
