Dab tsi yog cov ntaub nonwoven? Ib tug ua tiav cov lus qhia
Lub ntsiab
Nonwoven Web kev tsim yog ua tiav los ntawm txoj kev ntawm peb txoj kev tseem ceeb, uas yog, ntub nteg, thiab spun yaj. Txhua txoj kev suav nrog cov txheej txheem sib txawv ntawm kev sib cav sib ceg polymer lossis fibers nyob rau hauv daim ntawv txuas ntxiv rau cov ntawv thov. Cov txheej txheem ntawm cov txheej txheem qhuav los ua cov txheej txheem ntawm cov fibers lossis dispersing lawv mus rau ib txoj hlua ntawm cov txheej txheem no tsuas yog nws siv cua rau dispersing cov fibers. Lub nteg nteg teeb tsa ncua cov khoom siv raw hauv dej thiab tso nws los ntawm txoj siv sia ntawm txoj hlua khi rau kev tsim ib daim ntawv. Lub spun yaj txoj kev sib txawv hauv lub polymer no tau yaj thiab nteg tawm ncaj qha rau hauv txoj siv sia hauv cov lus no yog spun sib raug zoo thiab yaj. Cov hau kev no sib txawv ntawm cov kab ke ntawm cov fibers, txoj kev siv, thiab cov khoom siv, thiab txhua yam tsim nyog rau cov ntawv thov hauv kev tu cev, kev tsim kho, thiab cov ntawv kho mob.
Cov Tseem Ceeb
Nonwoven webs yog tsim los ntawm kev sib txuas ntawm peb cov txheej txheem yooj yim, uas yog, nteg ntaug, thiab spun yaj.
Qhuav nteg muaj kev txiav txim siab ntawm cov fibers thiab huab cua {{0} tso cov tswv yim uas siv cov cua.
Ntub nteg cov txuj ci tshem tawm cov fibers rau hauv dej da dej thiab disperses lawv mus rau ib txoj siv sia.
Spun yaj tau entailed melting ntawm yaj ntawm polymers thiab extruding filaments ncaj qha rau txoj siv sia.
Cov neeg nyiam tshaj plaws spun melt ntau yam yog spun bonding thiab yaj tshuab.
Cov qauv sib txawv tsim cov vev xaib uas tau taw qhia thiab sib khi ua ke.
Muaj txhua cov txheej txheem tau muaj kev siv tshwj xeeb hauv kev lag luam sib txawv.
Cov Tshawb Nrhiav Tseem Ceeb
Txuas ntxiv nonwoven npuag tsim cov txheej txheem ua kom yooj
Txij li thaum muaj peb qhov sib txawv nonwoven web sib sau tshuab los xaiv, cov khoom siv tau yooj yim los ntawm cov neeg muab khoom raws li qhov kawg- siv daim ntawv thov. Qhuav laid webs, piv txwv, tuaj yeem tsim tsim rau loft thiab hnov, ntub dej rau smoothness thiab sib npaug dispersal ntawm cov fiber ntau, thiab spun yaj rau qhov pom kev thiab lub zog. Cov versatility no tau hais tias tsis muaj kev sib koom ua ke tag nrho cov kev lag luam.
CUA - Cov txheej txheem nce cov txheej txheem fiber ntau ntxiv
Piv rau cov txheej txheem ua kom qhuav, huab cua {{0} tso cov txheej txheem ntawm cov pob zeb ua ntej kev tswj hwm kev tswj hwm kev ua haujlwm fiber ntau thiab ntom ntom ntom. Qhov qauv no txhim kho cov ntawv sib txawv thiab tso cai rau kev siv ntau hom ntawm cov fibers, tau tsim nyog nws ua eco- Tus phooj ywg thiab tsim nyog rau kev siv nyob rau hauv cov khoom lag luam uas tsis huv.
Ntub nteg cov txheej txheem muaj cov kev sib tw fiber ntau
Vim tias cov txheej txheem ntub dej tshem tawm cov dej hauv dej, nws muaj peev xwm ua tau rau lawv kom muaj kev sib tw ntawm ib txoj siv sia thiab tsim cov khaub ncaws tuab ntawm cov tuab tuab. Qhov no yog daim ntawv -}- Cov ntawv thov cov ntaub ntawv zoo tshaj plaws uas zoo tshaj plaws rau qhov twg cov kev ua haujlwm uas yog qhov tseem ceeb.
Spun yaj technology ua rau hloov dua siab tshiab los ntawm polymer rau fiber ntau
Hauv spun melt ntau lawm, npaj cov nqaij nyoos yog silestepped los ntawm ncaj qha melting ntawm polymer resins thiab extruding lawv mus rau hauv filaments, mob rau hauv cov webs. Qhov kev hloov pauv ncaj qha no tso cai rau ntau dua ntau lawm thiab rau kev tswj hwm ntawm kev siv, xws li hauv kev phais mob khaub ncaws hnav thiab muaj cov ntxaij vab tshaus.
Spun bonding thiab yaj tshuab: tau muaj txoj hauv kev
Spun Bonding thiab yaj tshuab yog ob qho tib si hauv spun melt tsev neeg tab sis kev sib txawv ntawm cov ntsiab lus ntawm cov lus ntawm cov lus qhia. Spun Bonding tsim cov filaments txuas ntxiv rau kev tsim cov webs zoo thiab khov kho, thaum yaj yaj tsim cov plaub hau uas zoo tshaj rau kev lim. Kev xaiv ntawm cov hau kev yog ua raws li qhov kawg- cov neeg tau txais khoom ntawm cov ua tau zoo.
Kev Ua Haujlwm thiab Fiber Qhia Kev cuam tshuam rau Lub Vev Xaib
Cov txheej txheem tau xaiv rau kev tsim kho web muaj cov nyhuv rau cov kev qhia fiber ntau thiab qhov no ntxiv cuam tshuam rau cov yam ntxwv kho tshuab ntawm ntau, thiab permeability. Qhuav Laid webs, tej zaum yuav muaj ntau cov kev qhia fiber ntau thiab siv tau ntau yam, thaum muaj cov ntaub ntawv yaj ua kom zoo dua rau kev txhim kho lub zog thiab lub zog.
Lub vev xaib tsis ua haujlwm tsim kev tsim kho tshiab thoob plaws kev lag luam
Nkag siab txog cov txheej txheem tsim kom muaj cov tuam txhab tsim kom muaj kev tsim kho hauv cov khoom tsim qauv, sib txuas los yog hloov kho cov ntaub ntawv qib siab los tsim cov ntaub ntawv qib siab. Kev nrhav kev tsim hluav taws xob pab txhawb kev lag luam xws li kev kho mob (piv txwv li, muaj kev kho lub ntsej muag, thiab kev tsim kho, ua kom pom kev zoo ntawm cov khoom siv science hauv kev tsim niaj hnub no.
