(1) dyeable polypropylene fiber
Polypropylene fiber tsis muaj affinity roj molecules, thiab nws cov molecular aggregation qauv yog ze heev. Pa polypropylene fiber ntau feem ntau nyuaj rau zas. Tam sim no, feem ntau ntawm cov polypropylene fiber muag nyob hauv kev lag luam yog xim los ntawm cov xim ua ntej spinning, tab sis cov chromatography tsis tiav, uas tsis tau sau, thiab cov kev txwv hauv ntau hom ntaub. Yog li ntawd, yuav ua li cas thov lub niaj hnub dyeing technology rau polypropylene fiber tau ua ib qho kev txhawj xeeb. Tam sim no, ntau hom dyeable polypropylene fiber ntau tau tsim. Cov yees no yuav muab faib ua ob pawg: ib qho yog copolymerization ntawm polymer lossis monomers muaj Pro roj pawg mus rau molecular saw ntawm polypropylene kom nws dyeable, thiab ob yog puas ntsoog thiab txo cov compact aggregation qauv ntawm macromolecules ntawm polypropylene los ntawm ib tug muab xaim hlau xaim. Cov polymers uas muaj cov niam txiv roj yog sib xyaw rau hauv cov polypropylene fiber kom daim fibers tsim ib co submicro discontinuities nrog siab zog interfacial, kom cov roj yuav nkag mus rau hauv cov fiber ntau thiab muab nrog cov pro roj pawg.
(2) industrial polypropylene filament thiab siab muaj zog polypropylene fiber
Muaj cov tshuaj polypropylene thiab lub zog siab polypropylene xa mus rau tag nrho cov polypropylene filament lwm yam tsis yog khaub ncaws. Nws cov khoom siv technology thiab kev siv cov cuab yeej no yog qhov txawv ntawm cov khaub ncaws. Siv lub tshuab polypropylene los yog siab muaj zog polypropylene fiber yuav tau los ntawm kev tswj cov spinning, ncab thiab cua sov txoj kev los ntawm kev xaiv cov polymer thiab ntau dua cov qauv polypropylene raw cov ntaub ntawv thiab kev txhim kho ntxiv thiab crystallinity ntawm macromolecule saw. Nws txoj kab ntim, qhov muaj zog thiab qhov yuav tsum muaj siab, thiab qhov loj hlob thaum tawg thiab qhov nce feem ntau tsawg.
