Yuav ua li cas PP Spunbond Nonwoven Npuag Ua Tshuab ua pp spunbond nonwoven ntaub?

Lub pp spunbonded nonwoven fabric uas ua los ntawm PP Spunbond Nonwoven Cov Ntawv Ua Kev Siv Lub Tshuab yog ib daim ntaub uas tsim ua tsis muaj spinning thiab weaving, thiab tsuas yog cov luv luv fibers lossis filaments oriented lossis randomly txheej txheem tsim lub web qauv. Tom qab ntawd nws yog txhawb los ntawm mechanical, kub-nplaum los yog tshuaj txoj kev. Lub pp spunbonded non-woven npuag yog pw tom qab lub polymer tau raug extruded thiab stretched rau daim nruam filaments nruam. Cov yeeb yaj kiab tau muab tso rau hauv net, thiab lub vev xaib ces nws tus kheej. Cohesion, thermal bonding, chemical tsevneeg lossis kev ua kom muaj zog tuaj yeem ua rau lub vev xaib rau hauv cov ntaub qhwv tsis-khaus.

Thaum PP PP spunbond nonwoven npuag tsim cav ua ib co ntaub nonwoven, nws tsis yog tias cov iav yog interwoven thiab braided ua ke, tab sis cov fibers yog ncaj qha ua ke ua ke los ntawm lub cev txhais tau tias. Cov txheej txheem tsis-woven lov los ntawm cov qauv siv tshuaj ua ke, thiab muaj cov yam ntxwv ntawm cov txheej txheem luv luv, ceev ceev ntau lawm, cov zis muaj nqis, luv nqi, daim ntawv thov dav, thiab ntau qhov chaw ntawm raw cov ntaub ntawv. Nws muaj zog, siab kub, kev laus ua hauj thiab kev ua haujlwm. UV, siab elongation, ruaj ntseg thiab ua tsis taus pa, kev tiv thaiv corrosion, hluav taws rwb thaiv tsev, tiv thaiv mite, tsis yog lom.

Cov ntaub ntub dej uas ntub tsis-woven yog qhib cov khoom siv ciaj rau cov dej nruab nrab rau hauv cov dej ua ke, thiab tib lub sij hawm sib tov sib txawv ntawm cov khoom siv fiber ntau los ua ib qho kev lag luam raug rho tawm, thiab tshem tawm cov kua pulp yog thauj mus rau web tsim mechanism, thiab cov fibre yog netted nyob rau hauv ib lub xeev ntub. Ua kom zoo rau hauv ib lub ntaub, tus spunbonded nonwoven npuag yog pw tom qab lub polymer tau raug extruded thiab stretched rau daim nruam filaments. Cov yeeb yaj kiab tau muab tso rau hauv lub vev xaib, thiab lub vas sab yog qhov sib npaug, thev plaub ua ke, sib koom ua ke lossis ua haujlwm. Qhov txuj ci tseem ceeb ua rau lub vas sab rau hauv cov ntaub qhwv tsis yog.
