Laminated nonwoven khoom
Txheej yog txheej txheem uas cov polymer yaj tau tso rau hauv lub substrate los ntawm lub tshuab txheej, thiab tom qab ntawd qhuav los ua ib zaj duab xis tiv thaiv ntawm lub substrate. High polymer films feem ntau yog polyethylene, polypropylene, lossis polyester, thiab muab faib ua cov yeeb yaj kiab dej thiab roj-raws li cov yeeb yaj kiab raws li lawv cov yam ntxwv. Cov txheej txheem dej-raws li txheej txheem yaj cov polymers siab hauv dej, tom qab ntawd coats cov kuab tshuaj ntawm cov ntaub, thiab thaum kawg tsim cov txheej txheej tiv thaiv los ntawm infrared ziab los yog ntuj ziab. Cov kuab tshuaj siv nyob rau hauv roj-raws li txheej tshuab yog tsuas yog UV photosensitive resin, uas tsuas yog qhuav los ntawm ultraviolet hluav taws xob. Cov txheej txheej oily muaj kev sib txhuam zoo thiab tuaj yeem siv tau ntev hauv ntau yam ecological lossis physicochemical ib puag ncig xws li infrared, ultraviolet, laser, cua, te, nag, daus, kua qaub thiab alkali.
Laminated nonwoven cov ntaub ntawv yog npaj los ntawm txheej nonwoven cov ntaub ntawv nrog siab polymer melts los yog cov kuab tshuaj, thiab yuav ua tau nyob rau hauv daim ntawv ntawm ib txheej los yog ob-txheej txheej, raws li qhia nyob rau hauv daim duab 1 thiab daim duab 2. Cov txheej txheej muaj peev xwm muab tau ib tug tej yam lub zog thiab khi lub nto fibers ntawm lub substrate, suppress kev sib nrig sib plam ntawm fibers, thiab txhim kho cov neeg kho tshuab cov khoom. Nyob rau tib lub sijhawm, kev siv cov yam ntxwv ntawm txheej txheej kuj tuaj yeem ua rau cov khoom siv nrog dej thiab roj repellent zog.
Hom ntawm cov ntaub ntawv laminated nonwoven
Tam sim no, cov substrates siv rau loj-scale siv laminated nonwoven cov ntaub ntawv yog tsuas yog koob punched nonwoven cov ntaub ntawv thiab spunbond nonwoven cov ntaub ntawv, nrog rau ib co siv hydroentangled nonwoven cov ntaub ntawv.
Laminated koob punched nonwoven khoom
Koob punched nonwoven cov ntaub ntawv yog tsim los ntawm fibers nrog peb-dimensional mesh qauv, uas muab koob punched nonwoven fabrics zoo permeability thiab pom kev ua tau zoo. Thaum lub sij hawm molding txheej txheem, rab koob pheej rov punctures lub web fibers, yuam cov fibers ntawm qhov chaw thiab hauv zos mus rau sab hauv ntawm lub web. Lub hauv paus fluffy lub vev xaib yog compressed, muab rab koob punched non-woven ntaub zoo heev txhua yam khoom. Txheej txheej ntawm rab koob punched cov ntaub ntawv uas tsis yog-woven nrog ib txheej ntawm high polymer zaj duab xis thiab molten zaj duab xis txheej tuaj yeem nkag mus rau hauv cov khoom siv sab hauv, txhim kho lub zog sib xyaw ntawm zaj duab xis txheej [5]. Rau ob lub ntsiab fiber ntau rab koob punched xav, molten zaj duab xis tsim ntau daim ntawv cog lus nrog cov fibers, ua rau cov khoom siv ntau compact.
Laminated spunbond nonwoven khoom
Spunbond nonwoven fabrics muaj cov khoom zoo xws li lub zog siab, du nto, mos tes xav, thiab ua haujlwm rau khoov thiab hnav, thiab tau siv dav hauv tsheb textiles. Cov fibers sab hauv ntawm spunbond nonwoven cov ntaub ntawv yog nruj nreem khi los ntawm dov cov ntsiab lus, thiab ib txheej ntawm high polymer yog sprayed rau saum npoo ntawm cov khoom. Lub molten zaj duab xis yog ib qho yooj yim rau kev sib txuas nrog cov fibers thiab dov cov ntsiab lus ntawm cov khoom siv spunbond, txhim kho kev ua tau zoo ntawm cov khoom laminated spunbond nonwoven.
Laminated hydroentangled nonwoven khoom
Cov txheej txheem txheej txheem ntawm hydroentangled nonwoven cov ntaub ntawv yog tias high-pressure ultra-fine dej dav hlau cuam tshuam lub web fiber, ua rau cov fibers nyob rau hauv lub fiber web mus entangle nrog ib leeg thiab tsim ib tug nruam nonwoven cov ntaub ntawv nyob rau hauv cov kev cuam tshuam ntawm lub dav hlau dej. Dej dav hlau nonwoven cov ntaub ntawv muaj zoo softness thiab elasticity zog. Piv nrog rau rab koob punched nonwoven cov ntaub ntawv nruj, lub zog ntawm rab koob dej cuam tshuam tsis muaj zog, ua rau qis qis ntawm cov fibers hauv cov dej koob punched nonwoven khoom, muab nws zoo dua breathability. Los ntawm kev siv cov txheej txheem txheej txheem, txheej txheej ntawm cov kua dej polymer siab yog coated rau saum npoo ntawm cov ntaub ntawv tsis yog cov ntaub ntawv, uas tsis yog tsuas yog muab cov yeeb yaj kiab tiv thaiv kev ua tau zoo, tab sis kuj muaj qhov ua tau zoo thiab tensile elasticity.
Dongguan Liansheng Nonwoven Technology Co., Ltd.tau tsim nyob rau hauv lub Tsib Hlis 2020. Nws yog ib tug loj-scale non-woven npuag ntau lawm enterprise integrating kev tshawb fawb thiab kev loj hlob, ntau lawm, thiab muag khoom. Nws tuaj yeem tsim ntau yam xim ntawm PP spunbond non-woven fabrics nrog qhov dav ntawm tsawg dua 3.2 meters los ntawm 9 grams mus rau 300 grams.
