Non-woven, tseem hu ua non-woven, yog ua los ntawm cov kev coj ua los yog kev siv roj, yog ib tiam tshiab ntawm cov phooj ywg zoo phooj ywg, nrog rau kev noo, ua pa, yoog, tsis muaj hluav taws, yooj yim zom, non-toxic non -txim, xim nplua nuj, nqi qis, rov ua dua thiab lwm yam. Xws li kev siv polypropylene (pp khoom) pellets li raw cov ntaub ntawv, kub kub yaj, spinneret, paving, kub coiling nruam ntau ntawm ib kauj ruam. Vim lub tsos ntawm daim ntaub thiab ib co kev ua tau zoo thiab hu ua daim ntaub.
Cov From Polpropylene spinning ncaj nraim rau hauv cov nyiaj kub, qhov zog ntawm qhov khoom yog zoo dua li cov khoom siv ntawm cov khoom siv fiber ntau, lub zog ntawm cov uas tsis yog directional, ntsug thiab kab sab siv zoo li. 8, nyob rau hauv kev tiv thaiv ib puag ncig, kev siv tam sim no siv cov ntaub qhwv raw li polypropylene, thiab hnab yas ntawm cov ntaub ntawv raw yog polyethylene, tab sis ob lub npe zoo li cov npe, tab sis cov qauv tshuaj sib txawv heev. Polyethylene chemical qauv muaj kev ruaj ntseg muaj zog heev, nyuab nyuab heev rau kev thuam, yog li lub hnab yas xav tau 300 xyoo los zom mus; thiab polypropylene chemical qauv tsis muaj zog, molecular saw yog yooj yim tawg, uas yuav ua tau zoo degraded, thiab hauv daim ntawv tsis-toxic mus rau lub voj voog tom ntej ntawm qhov chaw, ib Non-Woven Khw Hnab rau hauv 90 hnub yuav tsum tau kiag li decomposed. Thiab Cov Khw Muag Khoom Uas Tsis Muaj Woven yuav rov qab siv ntau tshaj 10 zaug, qhov chaw muaj paug thaj chaw tom qab muaj cov pa phem tsuas yog 10% ntawm cov hnab yas
Nonwovens qhuav fiber ntau yog polypropylene (PP), polyester (Petrus). Tsis tas li ntawd, muaj nylon (PA), viscose fiber, acrylic, sponge (HDPE), polyvinyl chloride (PVC). Raws li daim ntawv thov yuav tsum, cov ntaub ntawv tsis yog cov muab faib ua cov ntawv thov ib zaug thiab ua ob sab.
Tam sim no, tib neeg tsim fibers tseem yog thawj cov khoom uas tsis yog-khaus, thiab ua ntej 2007, qhov teeb meem no yuav tsis muaj qhov hloov loj. 63% ntawm cov fibers siv nyob rau hauv cov khoom ntawm nonwovens thoob ntiaj teb yog polypropylene, 23% polyester, 8% viscose, 2% acrylic fiber, 1.5% polyamide, thiab ntxiv 3% fiber.
