Raws li PetroChina thiab Sinopec tau pib tsim cov kab ntau lawm, tsim thiab muag lub qhov ncauj qhov ntswg, txhua tus tau maj mam kawm tias lub qhov ncauj qhov ntswg thiab roj yog qhov sib txuas ntxiv."Los ntawm Roj rau Mask" qhia tag nrho cov txheej txheem los ntawm roj mus rau daim npog qhov ncauj ib kauj ruam.Propylene tuaj yeem tau txais los ntawm roj av distillation thiab tawg.Propylene tuaj yeem ua polymerized kom tau polypropylene, thiab polypropylene tuaj yeem ua ntxiv rau hauv polypropylene fiber, uas yog qhov peb feem ntau hu ua polypropylene.Polypropylene fiber ntau (polypropylene) yog lub ntsiab fiber ntau raw khoom rau zus tau tej cov non-woven fabrics, tab sis nws tsis yog tib yam raw khoom.Polyester fiber ntau (polyester), polyamide fiber (nylon), polyacrylonitrile fiber (acrylic fiber), viscose fiber, thiab lwm yam tuaj yeem siv los tsim cov ntaub tsis-woven.
Tau kawg, ntxiv rau cov tshuaj fiber ntau saum toj no, cov fibers ntuj xws li paj rwb, hemp, wool, thiab txhob lo lo ntxhuav kuj tuaj yeem siv los tsim cov ntaub tsis-woven.Qee tus neeg feem ntau xav txog cov ntaub tsis-woven ua cov khoom siv tshuaj fiber ntau thaum lawv hais txog cov ntaub tsis-woven, uas yog qhov kev nkag siab yuam kev ntawm cov ntaub tsis-woven.Zoo li cov ntaub peb niaj hnub hnav, cov ntaub tsis-woven kuj tau muab faib ua cov tshuaj fiber ntau uas tsis yog-woven fabrics thiab natural fiber non-woven fabrics, tab sis cov tshuaj fiber ntau tsis-woven fabrics muaj ntau dua.Kuv xav ceeb toom rau txhua tus ntawm no tias tsis yog txhua yam khoom hu ua "paj rwb" yog ua los ntawm "paj rwb" fibers.Tseem muaj qee cov paj rwb phuam nyob rau hauv kev ua lag luam uas tau ua los ntawm cov tshuaj fibers, tab sis lawv xav zoo li paj rwb., koj yuav tsum xyuam xim rau cov khoom xyaw thaum yuav khoom)
