Cov fibers tseem ceeb siv hauv cov ntaub tsis-woven yog polypropylene (PP) thiab polyester (PET). Tsis tas li ntawd, kuj muaj nylon (PA), viscose fibers, acrylic, ethylene (HDPE), thiab chloroprene (PVC). Raws li daim ntawv thov, cov ntaub tsis-woven tau muab faib ua ob pawg: pov tseg thiab ruaj khov.
Raws li cov txheej txheem ntau lawm, nws tau muab faib ua:
1. Spinning non-woven npuag: Spinning txheej txheem yuav tsum txau cov dej siab micro ntws mus rau ib los yog ntau txheej ntawm fiber ntau mesh, ua rau cov fibers intertwine thiab ntxiv dag zog rau lub mesh rau ib tug tej yam kev mob ntawm lub zog.
2. Thaum tshav kub kub bonded non-woven npuag: Thaum tshav kub kub bonded non-woven npuag yog hais txog qhov sib ntxiv ntawm cov fibers los yog hmoov kub yaj cov ntaub ntawv rau cov fiber ntau, uas yog ces rhuab, melted, thiab txias los tsim ib daim ntaub.
3. Pulp air flow net forming non-woven fabric: Air flow net forming non-woven fabric kuj hu ua daim ntawv tsis muaj plua plav lossis qhuav papermaking non-woven fabric. Nws siv cov tshuab nqus cua ntws los txhawm rau txhawm rau cov ntoo fiber ntau rau hauv ib lub xeev fiber ntau, thiab tom qab ntawd siv cov txheej txheem cua ntws los sib sau ua ke cov fibers ntawm cov ntaub thaiv npog, thiab cov fiber mesh yog ntxiv rau hauv daim ntaub.
4. Cov ntaub ntub dej tsis-woven: Cov ntaub ntub tsis-woven yog txheej txheem ntawm loosening fiber ntau cov ntaub ntawv muab tso rau hauv cov dej nruab nrab rau hauv ib qho fibers, thiab sib tov cov khoom siv fiber ntau sib txawv los tsim cov fiber ntau suspension slurry. Lub suspension slurry yog thauj mus rau lub web forming mechanism, thiab fibers yog ces ntxiv rau hauv ib daim ntaub nyob rau hauv ib tug ntub lub xeev.
5. Spunbonded non-woven npuag: Spunbonded non-woven npuag yog ib hom non-woven npuag uas yog tsim los ntawm extruding thiab stretching polymers rau hauv nruam filaments, uas yog nteg rau hauv ib lub web. Lub vev xaib yog tom qab ntawd nws tus kheej sib koom ua ke, thermally bonded, chemically bonded, los yog mechanically reinforced kom tig lub web rau hauv cov ntaub tsis-woven.
6. Melt blown non-woven npuag: Cov txheej txheem ntawm yaj tshuab tsis-woven npuag muaj xws li kev pub mis polymer, yaj extrusion, fiber ntau tsim, fiber ntau txias, mesh tsim, thiab kev txhawb zog.
7. Koob punched non-woven npuag: koob punched non-woven npuag yog ib hom txheej txheem qhuav tsis-woven npuag, uas siv cov nyhuv puncture ntawm koob los txhawb cov fluffy fiber mesh rau hauv ntaub.
8. Stitching non-woven fabric: Stitching non-woven fabric is a type of dry process non-woven fabric, uas siv warp knitted coil qauv los txhawb cov fiber ntau mesh, yarn txheej, cov ntaub ntawv tsis-woven (xws li cov ntawv yas, yas nyias hlau ntawv, thiab lwm yam) los yog lawv ua ke los ua cov ntaub tsis-woven.
9. Hydrophilic non-woven npuag: feem ntau yog siv los tsim cov khoom siv kho mob thiab kev noj qab haus huv kom ua tiav tes zoo dua thiab tsis txhob khawb ntawm daim tawv nqaij. Cov ntaub so ntswg huv thiab cov ntaub huv huv siv cov dej ua haujlwm ntawm cov ntaub tsis-woven.
