Kukura kwekutanga uye kushandiswa kwepolypropylene fiber kwakatanga muna 1960s.Zvichienzaniswa nemamwe akajairika uye anoshandiswa zvakanyanya mafiber ekugadzira akadai sepolyester fiber uye acrylic fiber, kusimudzira uye kushandiswa kwepolypropylene fiber kwakatanga kunonoka.Panguva imwecheteyo, nekuda kwekubuda kwayo kuduku uye kushandiswa, kushandiswa kwayo kwakanga kusina kunyanya kuwanda mukutanga.Parizvino, nekuenderera mberi kwekuvandudza kwesainzi uye tekinoroji, kuenderera mberi kwekutsvaga nekuvandudza uye kuvandudzwa kwezvinhu zvitsva zvemachira, maitiro matsva uye matekinoroji matsva, kutsvagisa nekusimudzira uye kugadzirwa kwepolypropylene fiber kunotariswa zvishoma nezvishoma uye kushandiswa, kunyanya munguva pfupi yapfuura. makore makumi maviri, kukurumidza kwekukura kwayo kuri kukurumidza, uye zvishoma nezvishoma yave yakakurumbira faibha nyowani mumunda wemachira.
Polypropylene faibha izita rekutengesa repolypropylene faibha, uye imhando yepamusoro yepolymerized ine propylene semonomer.Iyo isiri-polar molecule.Polypropylene faibha ine chiedza chakananga giravhiti ye0.91, inova 3/5 yedonje uye viscose fiber, 2/3 yemvere dzemakwai uye polyester fiber, uye 4/5 ye acrylic fiber uye naironi fiber.Iine simba rakakwirira, imwe fiber simba re 4.4 ~ 5.28CN / dtex, yakaderera mwando kudzoka, kunyura kwemvura shoma, kunyanya simba rakafanana rakanyorova uye kuoma kwesimba, uye wicking yakanaka, kupfeka kwakanaka kuramba uye kusimba.Nekudaro, kubva pakuongorora kwayo macromolecular chimiro, kugadzikana kwayo kuchiedza uye kupisa hakuna kunaka, iri nyore kuchembera, uye kupfava kwayo kwakadzikira (140 ℃-150 ℃).Panguva imwecheteyo, chimiro chayo chemolecular chinoshaya mapoka anowirirana nemamorekuru edhayi, saka kushanda kwayo kwedhayi kwakashata.(Parizvino, painotenderera sosi yemafibhi, marudzi akasiyana-siyana akajeka epolypropylene fibers anogona kugadzirwa nekuwedzera colorbatch.)
