Dab tsi yog spunbond newwoven cov khoom?
Spunbond Nonwovenyog hom khoom lag luam tsim los ntawm extruding Molten Thermoplastic polymer rau hauv cov filegents nruam, tom qab ntawd uas tsev ua ke los ua lub vev xaib. Nws yog ib qho ntawm feem ntau, ntau yam, thiab tus nqi-} cov tshuab ua tau zoo tsis muaj txiaj ntsig.
Xav txog nws ua tus txheej txheem uas tsim cov ntaub ncaj qha los ntawm cov pellets yas, hla cov kauj ruam ib txwm muaj ntawm cov xov paj thiab tom qab ntawd nws los yog knitting cov xov paj. Qhov tshwm sim yog cov ntaub uas ua rau cov neeg ua kom tsis muaj kawg tau tso tseg thiab fused ua ke.
Lub Spunbond Manufacturing: Kauj Ruam - - kauj ruam
Cov txheej txheem txuas ntxiv mus, nrawm, thiab ua tau zoo heev, uas ua rau nws tus nqi qis.
Polymer Pub:Cov txheej txheem pib nrog thermoplastic polymer granules (feem ntaupolypropylene - pp, tab sis kuj polyester - tus tsiaj, nylon, thiab lwm yam). Cov pellets no pub rau hauv ib tug extruder.
Extrusion:Lub polymer yog rhuab nyob rau hauv nruj tswj kom txog thaum nws dhau los ua ib qho kua ntoo thiab kua.
Lus Askiv Hais txog:Lub molten polymer yog tom qab ntawd tau yuam los ntawm cov spinneret - ib lub phaj hlau muaj ntau txhiab tus heev. Cov ntaub ntawv ua no ntau txhiab tus ua kua ntev ntev polymer filaments.
Attenuation (kos duab):Raws li cov filaments tawm ntawm spinneret, lawv tam sim ntawd tau kos tawm (ncab thiab thinned thiab thinned) los ntawm qhov siab {} ceev cov dej ntws ntawm cua txias. Cov txheej txheem no oriess cov polymer lwg me me, uas nce siab ntauLub zog tensilentawm cov filaments.
Web Tsim:Kev txuas ntxiv, tam sim no {- Cov filaments yog pw kom haum, sib sau ua ke, web- zoo li qauv. Randomness yog qhov tseem ceeb rau cov npuag lub zog muaj zog hauv txhua qhov kev qhia (isotropic zog).
Tsevneeg Khuv:Lub vev xaib xoob ntawm filaments yuav tsum tau sib raug zoo los muab kev ntseeg siab thiab muaj zog. Cov qauv feem ntau yogQhov Kev Sib Laj Thermal(Siv cov menyuam neeg calender):
Lub vev xaib dhau ntawm lub nip ntawm ob lub rollers.
Ib tus menyuam tau du, thiab lwm tus muaj cov qauv engraved (piv txwv li, cov ntsiab lus, pob zeb diamond).
Cov cua sov thiab lub siab ntawm cov ntsiab lus ntawm Faus cov filaments ua ke, tsim kom muaj zog tab sis hloov ntaub zoo. Qhov no yog vim li cas koj feem ntau pom cov xim tsaus muag ntawm lub hnab ntim khoom pov tseg lossis cov txheej sab hauv ntawm lub pawm.
Winding:Cov ntaub ua tiav lawm yog qhov txhab rau hauv jumbo yob rau kev hloov pauv hloov mus rau tom cov khoom muag zaum kawg.
Cov yam ntxwv tseem ceeb thiab cov txiaj ntsig zoo
Spunbond Nonwovens yog tus nqi rau ib pawg ntawm cov khoom uas ua rau lawv zoo tagnrho rau ntau cov ntawv thov.
| Tus yam ntxwv | Hom kom zoo dua & vim li cas nws tseem ceeb |
|---|---|
| Siab zog & ruaj khov | Cov filaments nruam tsim cov ntaub npuag nrog cov tensile zoo heev, kua muag, thiab tawg lub zog. Nws yog ntau zog tshaj ntub - laid lossis qhuav - laid tsis muaj qhov hnyav. |
| Tus nqi - ua hauj lwm zoo | Lub siab - ceev cov txheej txheem los ntawm cov ntaub ntawv ua tiav los ntawm cov ntaub ntawv tiav los ua tiav cov ntaub ua nws heev yig rau kev loj heev rau cov khoom siv. |
| Porosity & Porimity | Qhov qhib, Randed web qauv tso cai huab cua thiab noo vapor kom dhau los yooj yim. |
| Tshuaj Kuj | Tshwj xeeb tshaj yog thaum ua los ntawm polypropylene, nws tiv taus ntau cov acids, alkalis, thiab cov kuab tshuaj. |
| Lub teeb yuag | Nws tuaj yeem tsim nyob rau hauv qhov hnyav qis heev (piv txwv li, 10 grams ib square meter {} gsm) thaum tseem tswj lub zog muaj zog. |
| Softness | Niaj hnub nimno Spunbond ntaub ua haujlwm tuaj yeem tsim cov khoom siv los ua qhov muag muag heev, uas yog qhov tseem ceeb rau cov khoom lag luam tu cev. |
| Dej Xiav Dej | Polypropylene is inherently hydrophobic (water-repelling), making the fabric an excellent barrier to liquids. |
