Yuav ua li cas lub plawv txheej meltblown daim ntaub ntawm lub npog qhov ncauj tsim?

Cov ntaub ntawv nonwoven yog dab tsi?

Raws li lub teb chaws tus qauv GB/T {{{0}}}, cov ntaub ntawv uas tsis yog-woven, feem ntau hu ua non-woven fabrics, xa mus rau cov nplooj ntawv thiab fibers ua los ntawm oriented los yog randomly teem fibers ua ke nrog ib leeg los ntawm kev sib txhuam, cohesion los yog bonding los yog ib tug ua ke ntawm txoj kev no. Netting los yog batting (tsis suav cov ntawv, woven fabrics, tufted fabrics, stitchbonded fabrics nrog stitched yarns thiab ntub milled felts). Cov fibers siv tau yog cov fibers ntuj lossis tshuaj fibers; lawv tuaj yeem yog cov fibers luv, filaments lossis cov khoom fibrous tsim ntawm qhov chaw. Txhawm rau kom paub qhov txawv ntawm cov ntaub ntawv ntub dej los ntawm cov ntawv, nws tseem tau teev tseg tias fibers nrog qhov sib piv ntau dua 300 tus lej rau ntau dua 50 feem pua ​​​​ntawm tag nrho cov khoom, lossis fibers nrog qhov sib piv ntau dua 300 tsuas yog tus account rau ntau tshaj. 30 feem pua ​​​​ntawm tag nrho cov huab hwm coj. Txawm li cas los xij, cov uas nws qhov ceev tsawg dua 0.4g / cm3 yog cov ntaub ntawv tsis-woven, txwv tsis pub lawv yog ntawv.

Lub "lub plawv txheej" meltblown daim ntaub ntawm daim npog qhov ncauj

Cov qhov ncauj qhov ntswg feem ntau yog tsim los ntawm peb txheej ntawm cov ntaub tsis woven, cov txheej sab hauv thiab sab nrauv feem ntau yog spunbond ntaub (S), thiab "lub plawv txheej" yog meltblown nonwoven fabric (M), uas yog cov khoom tseem ceeb rau lub npog ntsej muag kom ua tiav. lub barrier tiv thaiv muaj nuj nqi. Tseem muaj SMS, SMMS, SSMMS thiab lwm yam ntawm spunmelt composite nonwovens.

Cov yam ntxwv ntawm cov khoom siv nonwoven

1. Cov ntaub ntawv ntawm plaub cov ntaub ntawv hloov tau yooj yim ntawm cov tsoos textiles, plastics, tawv thiab ntawv. Kev siv thev naus laus zis sib txawv txiav txim siab qhov ua tau zoo ntawm cov ntaub ntawv tsis-woven. Qee cov ntaub ntawv nonwoven zoo li cov tsoos textiles, xws li spunlace nonwoven cov ntaub ntawv; ib co zoo li ntawv, xws li cov ntawv qhuav nonwoven cov ntaub ntawv; thiab qee qhov zoo li tawv, xws li cov ntaub ntawv tsis-woven. Base PU tawv thiab lwm yam.

2. Cov tsos thiab cov qauv ntawm cov ntaub ntawv tsis-woven muaj ntau yam. Kev sib txawv ntawm cov khoom siv raw thiab kev siv tshuab siv hauv cov ntaub ntawv nonwoven txiav txim siab qhov sib txawv ntawm cov tsos thiab cov qauv ntawm cov ntaub ntawv nonwoven. Los ntawm cov qauv kev pom, feem ntau cov ntaub ntawv tsis-woven yog cov qauv fiber ntau. Muaj ib txheej nyias mesh geometric qauv nyob rau hauv uas fibers yog teem nyob rau hauv ob qhov ntev, thiab network geometric qauv nyob rau hauv uas fibers yog teem nyob rau hauv peb qhov ntev. Qee cov fibers yog entangled nrog fibers. Cov qauv tsim fiber ntau, qee qhov yog cov qauv uas cov fibers sib txuas ntawm cov ntsiab lus sib txuas, qee qhov yog cov kab sib txuas fiber ntau uas kho cov ntsiab lus fiber ntau txuas nrog cov tshuaj nplaum, thiab qee qhov yog cov kab hluav taws xob fiber ntau. Cov qauv geometric tsim los ntawm kev sib sau ua ke; los ntawm qhov pom ntawm qhov pom, cov ntaub ntawv tsis-woven yog ntaub-zoo li, mesh-zoo li, xav-zoo li, ntawv-zoo li, thiab lwm yam.

3. Ntau yam ntawm cov khoom ntawm cov ntaub ntawv nonwoven. Vim muaj ntau haiv neeg ntawm kev xaiv raw khoom thiab kev siv thev naus laus zis, kev ua haujlwm ntawm cov ntaub ntawv tsis-woven yog khi rau ntau haiv neeg. Qee cov khoom siv tau yooj yim heev thiab qee qhov nyuaj heev; qee cov ntaub ntawv muaj zog heev thiab qee qhov tsis muaj zog; qee cov ntaub ntawv yog ntom thiab qee qhov yog fluffy heev; Tab sis nyias nyias. Yog li ntawd, qhov kev ua tau zoo ntawm cov khoom siv tuaj yeem tsim raws li kev siv cov khoom siv tsis-woven, thiab tom qab ntawd cov txheej txheem thev naus laus zis thiab cov ntaub ntawv raw tuaj yeem raug xaiv thiab txiav txim siab.

Classification ntawm cov ntaub ntawv nonwoven

Cov hom ntawm cov ntaub ntawv nonwoven tuaj yeem muab faib ua raws li txoj hauv kev tsim lub vev xaib, txoj kev txhawb nqa lossis siv. Raws li txoj kev tsim lub vev xaib, nws tuaj yeem muab faib ua lub vev xaib qhuav (cov tshuab siv lub vev xaib, lub vev xaib huab cua), lub vev xaib ntub dej (rotary web method, inclined web method) thiab polymer spun web (spun-bonded method, yaj-blown method), zaj duab xis splitting txoj kev, electrostatic method). Raws li txoj kev txhawb nqa, nws tuaj yeem muab faib ua cov cuab yeej cuab tam (txoj kev punching txoj kev, txoj kev spunlace, txoj kev stitching), thermal bonding (kub dov txoj kev, cua kub txoj kev, ultrasonic bonding txoj kev) thiab tshuaj bonding (dipping, txau, ua npuas ncauj, luam ntawv, kuab tshuaj, thiab lwm yam). Raws li kev siv, nws tuaj yeem muab faib ua cov khoom siv kho mob thiab huv, lim cov ntaub ntawv, cov khoom siv geosynthetic, cov khoom siv tsheb, cov ntaub ntawv siv, cov khoom siv hluav taws xob thiab hluav taws xob, cov khoom ntim khoom, cov khoom siv ua liaj ua teb thiab cov khoom siv kho kom zoo nkauj hauv tsev, thiab lwm yam. txhua yam ntawm peb lub neej niaj hnub.
