PP spunbond nonwoven npuag yog hom nrov ntawm cov ntaub nonwoven uas tau siv dav hauv ntau yam xws li kev ua liaj ua teb, ntim khoom, kev kho mob, thiab lwm yam. Nws yog tsim los ntawm polypropylene polymers, uas yog hloov mus rau hauv lub web-zoo li qauv los ntawm ib tug complex txheej txheem.
PP spunbond nonwoven npuag yog tsim los ntawm thawj melting polypropylene pellets nyob rau hauv ib tug extruder. Lub melted polymer yog ces extruded los ntawm spinnerets los tsim ib lub web zoo li qauv. Lub vev xaib no txuas ntxiv ua tiav los ntawm kev ncab thiab txuas cov fibers ua ke los tsim cov ntaub muaj zog, ruaj khov.
Cov txheej txheem ntawm kev ncab thiab kev sib txuas cov fibers yog ib feem tseem ceeb ntawm cov txheej txheem tsim khoom. Nws suav nrog kev hla lub vev xaib los ntawm ntau cov chais, uas siv cov cua sov thiab lub zog kom fuse cov fibers ua ke. Qhov no tsim cov ntaub uas muaj zog, ruaj khov, thiab muaj lub zog tensile siab.
Thaum PP spunbond nonwoven npuag raug tsim, nws tuaj yeem ua tiav los muab nws cov khoom tshwj xeeb xws li dej tsis kam, hluav taws kub, thiab UV tsis kam. Nws kuj tseem tuaj yeem dyed, luam tawm, lossis laminated kom muab nws ua haujlwm ntxiv.
Hauv kev xaus, tsim PP spunbond nonwoven npuag yog txheej txheem nyuaj thiab nyuaj uas cuam tshuam nrog melting, extrusion, stretching, bonding, thiab xov. Txawm tias muaj kev nyuaj ntawm cov txheej txheem, cov khoom kawg yog cov ntaub ntawv zoo uas tau siv dav hauv ntau daim ntawv thov.
