Dab tsi yog non-woven fabric manufacturing process?
Web tsim
Nonwovens web tsim yog thawj kauj ruam hauv cov txheej txheem tsim khoom, uas yog hais txog kev tsim cov fiber ntau webs los ntawm kev siv tshuab lossis tshuaj siv los ntawm fibers lossis cov ntaub ntawv hmoov. Cov txheej txheem muaj xws li cua kub sib sau, acupuncture forming, spunlace forming, thiab spinning.
Kev sib txuas hauv Web
Web bonding yog hais txog kev sib xyaw ntawm cov fibers lossis cov ntaub ntawv los tsim cov ntaub tsis-woven nrog ib lub zog. Cov txheej txheem muaj xws li thermal bonding, chemical bonding, thiab pressure bonding.
Kev kho mob tiav
Tom qab cov ntaub ntawv tsis-woven yog sib txuas, txhawm rau hloov mus rau nws daim ntawv thov hauv ntau qhov chaw, kev kho tiav yuav tsum tau nqa tawm kom muab ntau yam khoom, xws li: hydrophilic, dej repellent, nplaim hluav taws, antibacterial, deodorant, anti-aging. , anti-slip, thiab lwm yam .. Kev ua tiav suav nrog embossing, luam ntawv, laminating, txheej thiab lwm txoj kev.
Hloov pauv
Tom qab cov kauj ruam saum toj no, cov ntaub tsis-woven tuaj yeem txiav lossis hloov mus rau hauv cov khoom tsim nyog, xws li txheej txheej ntawm cov ntaub so ntswg, txheej txheej ntawm cov ntaub qhwv, cov hnab tsis-woven, txheej txheej ntawm lub qhov ncauj qhov ntswg, thiab lwm yam.
Nonwovens yog siv nyob rau hauv ntau hom kev siv, cov hauv qab no yog qee qhov sib xws:
Cov khoom siv kho mob: cov ris tsho phais, lub kaus mom phais, lub qhov ncauj qhov ntswg, cov ntaub qhwv kom tsis muaj menyuam, thiab lwm yam.
Cov khoom siv hauv tsev: wallpaper, curtains, nplooj ntawv, lawn npog, ntaub pua plag, qhov rais ntaub, chav ua noj so, thiab lwm yam.
Cov khoom siv: lim cov ntaub ntawv, cov ntaub ntawv thermal rwb thaiv tsev, cov ntaub ntawv tsis zoo hauv tsev, cov khoom siv hauv tsheb, cov khoom ntim, thiab lwm yam.
Cov khoom siv ua liaj ua teb: cov yeeb yaj kiab ua liaj ua teb, cov hnab ntim txiv hmab txiv ntoo, cov kab mob tiv thaiv kab mob khi daim ntaub, cog hnub ci net, tsev cog khoom npog daim ntaub, thiab lwm yam.
Cov khoom tiv thaiv ib puag ncig: cov hnab khib nyiab, ib puag ncig lub hnab yuav khoom, cov thawv ntim khoom noj, thiab lwm yam.
Textiles: ris tsho hauv qab, khau, hnab looj tes, kaus mom, khaub ncaws, thiab lwm yam.
Spunbond txoj kev ntawm cov khoom tsis woven
Spun-bonded non-woven fabrics yog tsim los ntawm kev tso cov filaments rau hauv lub vev xaib tom qab cov polymer tau raug extruded thiab ncab los ua ib qho txuas txuas ntxiv, thiab tom qab ntawd sib txuas los ntawm nws tus kheej, thermally bonded, chemically bonded los yog mechanically reinforced los ua lub vev xaib mus rau hauv ib qho chaw. non-woven npuag. Cov txheej txheem no tuaj yeem siv cov ntaub ntawv sib txawv los tsim cov ntaub tsis-woven nrog cov khoom sib txawv, xws li polypropylene, polyester, thiab lwm yam. Cov txheej txheem ntawm spunbond nonwoven npuag feem ntau suav nrog cov kauj ruam hauv qab no:
1. Kev xaiv fiber ntau thiab pretreatment: Kev xaiv cov fibers yog ib qho tseem ceeb heev, thiab cov khoom sib txawv yuav tsum tau xaiv raws li kev siv thiab kev xav tau sib txawv. Hauv pretreatment, cov fibers yog ntxuav, qhuav thiab lwm yam.
2. Spinning ntawm fibers: Cov fibers yog spun los ntawm lub tshuab textile los tsim ib lub web fiber.
3. Kev kho mob Bonding: Lub web fiber yog sib txuas ua kom cov fibers sib txuas. Cov txheej txheem kev sib txuas tuaj yeem siv tshuaj sib txuas, thermal bonding lossis mechanical bonding.
4. Kev ua tiav cov khoom tiav: Cov khoom sib txuas fiber ntau tau ua tiav rau hauv cov khoom tiav xws li winding thiab txiav los ua cov ntaub tsis-woven ntawm cov duab sib txawv.
Spunbond non-woven fabrics muaj cov yam ntxwv ntawm kev nqus dej zoo, muaj zog huab cua permeability, softness thiab kev nplij siab, thiab yog siv dav hauv kev kho mob, tu cev, khoom vaj khoom tsev, khaub ncaws, ntim thiab lwm yam.
Spunlace txoj kev ntawm non-woven ntau lawm
1. Pub paj rwb
Thaum lub sijhawm ua haujlwm no, cov neeg ua haujlwm muab cov paj rwb nyoos rau hauv pem teb hauv qab cov tshuab. Lub feeder ces cia li ntes cov fiber ntau thiab thauj mus rau cov channel rau cov txheej txheem tom ntej.
2. Txawv teb chaws fiber ntau sorting
Thaum lub sij hawm tus txheej txheem no, lub txawv teb chaws fiber sorter tshem tawm txawv teb chaws teeb meem, me me ntawm hlau thiab me me daim ntawm paj rwb noob. Txawm li cas los xij, cov txheej txheem no tsuas yog tshem tawm ib feem ntawm cov impurities, thiab thaum kawg cov khoom tiav yuav tsum tau kuaj xyuas kom tshem tawm cov teeb meem ntawm daim ntaub.
3. Carding
Lub tshuab carding stretches thiab so cov paj rwb fibers kom tag nrho cov fibers tau nteg tawm zoo li ib daim ntawv; Tom qab ntawd lawv raug hloov mus rau qhov txheej txheem hla-lapping. Lub luag haujlwm tseem ceeb yog tshem tawm cov impurities hauv cov fibers dua thiab comb cov fibers (xws li combing plaub hau) kom lawv zoo zoo.
4. Hla-lapping
Nyob rau hauv lub tshav pob ntawm nonwoven fabric ntau lawm tam sim no, muaj ob hom nteg nets. Ib tug yog ncaj nteg net, lwm tus yog cross nteg net. Yog vim li cas rau kev xaiv cross-ntes mesh yog tias lub zog tensile ntawm ntoo khaub lig-ntev mesh yog 1-2 npaug ntawm cov kab ncaj nraim. Tab sis qhov tsis zoo yog qhov hnyav tsis sib xws
5. Cov txheej txheem kev teeb tsa
Hauv cov txheej txheem no, cov paj rwb fiber ntau yog ncab 2-3 zaug. Cov nyhuv ntawm qhov nro no yog ua kom lub vev xaib nonwoven ntau dua, nrog qhov hnyav nruab nrab zoo dua thiab lub zog tensile zoo dua hauv CD thiab MD.
6. Spunlace
Spunlace yog qhov txuas tseem ceeb tshaj plaws hauv kev tsim khoom. Nyob rau hauv kev kub siab, koob dej hla los ntawm cov paj rwb net, ua rau cov paj rwb fiber ntau nruj entangled, thiab thaum kawg tsim rau hauv ib lub spunlace nonwoven ntaub. Lub fluff thiab thickness ntawm cov paj rwb muaj peev xwm tswj tau los ntawm kev kho lub siab.
7. Yob
Tom qab spunlace, cov khoom yuav dov mus rau hauv ib lub yob.
8. tshuaj dawb thiab ziab
Txij li thaum peb siv cov paj rwb nyoos fibers, yam peb tsim yog cov paj rwb nyoos. Tam sim no, paj rwb yog grey. Cov txheej txheem no hu ua bleaching thiab ziab. Grey xim paj rwb yob yuav nkag mus rau hauv ntab. Nyob rau hauv lub lauj kaub bleaching, peb siv hydrogen peroxide kom bleach nyob rau hauv qhov kub thiab txias rau 4 teev. Tom qab bleaching, laps yog qhuav thiab ntim.
9. Kev tshuaj xyuas cov ntaub ntawv hauv computer
Peb muaj 23 daim ntaub tshuaj xyuas tshuab, tswj lub computer. Yog tias muaj qhov tsis xws luag, lub tshuab yuav cia li nres thiab ceeb toom rau cov neeg ua haujlwm nrog lub teeb dawb (tso pom qhov tsis xws luag nyob rau pem hauv ntej) thiab lub teeb xiav (pom qhov tsis xws luag nyob rau sab nraub qaum), thiab lub tshuab yuav rov ua haujlwm tom qab cov khoom tsis raug xaiv. .
10. Txiav
Kho cov riam thiab txiav raws li qhov dav xav tau ntawm cov neeg siv khoom sib txawv. Thaum txiav, ob tus neeg ua haujlwm yuav ntsuas thiab sau qhov dav ntawm qhov txiav ua ke kom ntseeg tau tias qhov dav ntawm cov khoom zoo ib yam.
11. Cov khoom tiav - ntim
Ntim raws li kev ntim khoom ntawm cov neeg siv khoom sib txawv.
