Nonwoven npuag yog cov ntaub zoo li cov ntaub ntawv ua los ntawm cov fibers ntev, sib koom ua ke los ntawm kev siv tshuaj lom neeg, khoom siv hluav taws xob, kev kho cua sov los yog hnyav. Lub sij hawm yog siv nyob rau hauv kev lag luam textile manufacturing los qhia cov ntaub, xws li kev xav, uas tsis yog woven los yog knitted. Cov ntaub ntawv tsis-woven feem ntau tsis muaj zog tshwj tsis yog tias muaj zog los yog txhawb nqa los ntawm kev txhawb nqa. Nyob rau hauv xyoo tas los no, nonwovens tau dhau los ua lwm txoj rau polyurethane ua npuas ncauj.
Hauv tsab xov xwm no, peb yuav tshawb txog lub ntsiab lus ntawm cov ntaub tsis-woven thiab muab qee qhov piv txwv. Tsis tas li ntawd, peb yuav qhia qee qhov tseeb nthuav txog cov ntaub tsis-woven. Cia peb pib!
Hauv kab ntawv no peb yuav npog:

Tshawb nrhiav qhov sib txawv ntawm cov ntaub tsis-Woven
Non-woven fabrics yog dav siv nyob rau hauv kev ua lag luam niaj hnub no vim lawv versatility thiab yooj yim ntawm ntau lawm. Lawv yog tsim los ntawm kev sib txuas cov fibers ua ke yam tsis muaj kev sib tsoo los yog kev siv phau ntawv koom nrog. Hauv seem no, peb yuav tshawb txog ntau yam ntawm cov ntaub tsis-woven muaj nyob hauv khw thiab lawv cov kev siv tshwj xeeb.
Hom Tsis-Woven Fabrics
Cov ntaub tsis-woven tuaj yeem muab faib ua ntau hom nyob ntawm cov khoom siv thiab cov txheej txheem ntawm kev tsim khoom. Qee yam tseem ceeb ntawm cov ntaub tsis-woven muaj xws li:
- Spunbond Non-Woven Fabric: Hom no tsis-woven npuag yog tsim los ntawm melting thiab extruding polymer rau hauv zoo filaments. Cov filaments no ces muab tso rau ntawm ib txoj siv conveyor thiab sib txuas ua ke siv lub zog kub. Spunbond non-woven fabrics muaj zog, nyias, thiab zoo tagnrho rau siv nyob rau hauv kev tsim kho, kev nyab xeeb, thiab kev siv.
- Meltblown Non-Woven Fabric: Hom non-woven npuag no yog tsim los siv cov txheej txheem zoo xws li spunbond non-woven fabric. Txawm li cas los xij, cov filaments luv dua thiab zoo dua, ua rau cov ntaub npuag zoo dua thiab ntau dua. Meltblown non-woven fabrics feem ntau yog siv rau hauv cov khoom kho mob thiab tu cev vim lawv muaj peev xwm lim tawm cov khoom me me.
- Needle Punch Non-Woven Fabric: Hom non-woven npuag no yog tsim los ntawm kev hla cov fibers los ntawm ntau cov koob uas yuam kom cov fibers sib cuam tshuam thiab sib koom ua ke. Koob punch non-woven fabrics muaj zog, ruaj, thiab zoo meej rau kev siv hauv cov khoom uas xav tau ib puag ncig huv thiab nyab xeeb.
- Npuag Laid Non-Woven Fabric: Hom non-woven npuag no yog tsim los ntawm kev hloov cov khoom ntuj lossis hluavtaws fibers rau hauv slurry. Cov slurry yog ces kis tawm ntawm ib txoj siv conveyor thiab dhau los ntawm ib tug series ntawm rollers kom tshem tawm cov dej ntau dhau. Cov ntaub ntub dej tsis-woven feem ntau yog siv rau hauv kev tsim cov ntaub so, lim dej, thiab lwm yam khoom uas yuav tsum muaj cov khoom muag muag thiab nqus tau.
Xaiv Txoj Cai Tsis-Woven Fabric
Thaum xaiv cov ntaub tsis-woven, nws yog ib qho tseem ceeb uas yuav tau xav txog kev siv tshwj xeeb thiab cov kev xav tau ntawm cov neeg siv kawg. Qee yam uas yuav tsum xav txog muaj xws li:
- Lub zog thiab Durability: Qee hom tsis-woven fabrics muaj zog thiab ruaj khov dua li lwm tus, ua rau lawv zoo tagnrho rau kev siv hauv cov khoom uas yuav tsum tau muaj zog thiab kav ntev.
- Absorbency: Cov ntaub ntub dej tsis-woven yog qhov zoo tshaj plaws rau kev siv hauv cov khoom uas yuav tsum tau muaj qib siab absorbency, xws li cov ntaub so ntswg thiab cov lim dej.
- Kev huv huv thiab kev nyab xeeb: koob punch non-woven fabrics yog zoo meej rau siv nyob rau hauv cov khoom uas xav tau ib tug huv si thiab nyab xeeb ib puag ncig, xws li cov khoom kho mob thiab tu cev.
- Softness thiab Comfort: Meltblown non-woven fabrics yog zoo tagnrho rau siv nyob rau hauv cov khoom uas yuav tsum tau ib tug mos mos thiab xis cov ntaub ntawv, xws li cov pawm thiab feminine tu cov khoom.
Yuav ua li cas Nonwoven Fabric yog tsim
Ib txoj kev nrov rau kev tsim cov ntaub nonwoven yog txheej txheem spunbond. Cov txheej txheem no suav nrog extruding polymer resin los ntawm lub nozzle los tsim cov filaments. Cov filaments yog ces muab tso rau hauv ib txoj siv txav, qhov uas lawv tau sib koom ua ke siv thermal lossis tshuaj sib txuas. Lub vev xaib ntawm cov fibers tom qab ntawd raug mob rau hauv yob thiab tuaj yeem ua tiav rau hauv cov khoom tiav.
Txheej txheem Meltblown
Lwm txoj hauv kev los ua cov ntaub nonwoven yog cov txheej txheem meltblown. Cov txheej txheem no suav nrog extruding polymer resin los ntawm lub nozzle thiab tom qab ntawd siv cua kub kom ncab thiab tawg cov filaments rau hauv cov fibers zoo heev. Tom qab ntawd cov fibers tau muab tso rau hauv ib qho kev txav mus los, qhov chaw uas lawv tau sib koom ua ke siv thermal bonding. Lub vev xaib ntawm cov fibers tom qab ntawd raug mob rau hauv yob thiab tuaj yeem ua tiav rau hauv cov khoom tiav.
Txoj kev Drylaid
Cov txheej txheem drylaid yog lwm txoj hauv kev los tsim cov ntaub nonwoven. Cov txheej txheem no suav nrog kev tso cov fibers rau hauv txoj siv txav thiab tom qab ntawd siv daim ntawv qhia hnub los khi cov fibers ua ke. Cov fibers tuaj yeem tsim los ntawm ntau yam khoom siv, nrog rau cov paj rwb, thiab cov ntaub npuag tuaj yeem siv rau ntau yam kev siv.
xaus
Yog li, non-woven txhais tau tias yog ntaub uas tsis woven. Nws tuaj yeem ua los ntawm fibers lossis yas thiab tuaj yeem siv rau ntau yam. Nws yog ib qho khoom siv zoo rau kev ua cov khoom uas yuav tsum tau mos los yog absorbent. Yog li, lwm zaus koj yuav tsum yuav ib yam dab tsi, koj tuaj yeem txiav txim siab rau koj tus kheej yog tias tsis yog-woven yog qhov kev xaiv zoo. Tej zaum koj yuav xav tsis thoob los ntawm qhov koj tuaj yeem nrhiav tau!
