Non-woven fabric / nonwoven fabric, raws li cov khoom siv tsis yog cov khoom siv ib txwm siv, yog cov khoom siv tseem ceeb thiab tseem ceeb hauv lub neej niaj hnub vim nws cov khoom tshwj xeeb thiab ntau yam kev siv. Nws tsuas yog siv lub cev los yog tshuaj txoj hauv kev los sib cog lus thiab sib cuam tshuam fibers ua ke, tsim cov ntaub nrog qee lub zog thiab softness. Muaj ntau yam khoom siv thev naus laus zis rau cov ntaub ntawv tsis-woven, thiab cov txheej txheem ntau lawm muab cov ntaub ntawv tsis-woven txawv cov yam ntxwv kom tau raws li ntau yam kev xav tau.
Hauv ntau qhov kev lag luam xws li lub neej niaj hnub, kev lag luam, thiab kev tsim kho, cov ntaub tsis-woven tuaj yeem pom ua si lawv lub luag haujlwm:
1. Hauv kev saib xyuas kev noj qab haus huv: daim npog qhov ncauj, lub tsho phais, cov khaub ncaws tiv thaiv, hnav khaub ncaws kho mob, cov ntaub so ntswg huv, thiab lwm yam.
2. Cov khoom siv lim: lim cua, lim kua, roj-dej separators, thiab lwm yam.
3. Geotechnical cov ntaub ntawv: kua dej network, anti-seepage membrane, geotextile, thiab lwm yam.
4. Khaub ncaws accessories: khaub ncaws hauv ob sab phlu, hauv ob sab phlu, lub xub pwg pluaj, thiab lwm yam.
5. Cov khoom siv hauv tsev: ntaub pua txaj, ntaub pua rooj, ntaub ntaub, thiab lwm yam.
6. Automotive sab hauv: lub rooj zaum hauv tsheb, qab nthab, ntaub pua plag, thiab lwm yam.
7. Lwm tus: cov khoom ntim, cov roj teeb cais, cov khoom siv hluav taws xob rwb thaiv tsev, thiab lwm yam.
Cov txheej txheem tseem ceeb ntawm cov ntaub tsis-woven muaj xws li hauv qab no:
1. Meltblown method: Meltblown method yog ib txoj hauv kev melting thermoplastic fiber ntau cov ntaub ntawv, txau tawm ntawm kev kub ceev los tsim cov filaments zoo, thiab tom qab ntawd khi lawv ua ke los tsim cov ntaub tsis-woven thaum lub caij txias.
-Cov txheej txheem ntws: polymer pub → yaj extrusion → fiber ntau tsim → fiber ntau txias → web tsim → reinforcement rau hauv ntaub.
-Features: Fine fibers, zoo pom kev ua tau zoo.
-Daim ntawv thov: Cov ntaub ntawv lim dej zoo, xws li lub qhov ncauj qhov ntswg thiab cov ntaub ntawv lim dej kho mob.
2. Spunbond txoj kev: spunbond txoj kev yog cov txheej txheem ntawm melting thermoplastic fiber ntau cov ntaub ntawv, tsim nruam fibers los ntawm high-ceev stretching, thiab ces txias thiab bonding lawv nyob rau hauv cov huab cua los ua cov ntaub ntawv uas tsis yog-woven.
-Cov txheej txheem ntws: polymer extrusion → stretching rau daim ntawv filaments → nteg rau hauv ib lub mesh → bonding (self bonding, thermal bonding, chemical bonding, or mechanical reinforcement). Yog hais tias ib puag ncig cov menyuam siv los siv lub siab, cov ntsiab lus kub kub tsis tu ncua (pockmarks) feem ntau pom ntawm cov ntaub npog.
-Feature: zoo mechanical zog thiab zoo heev breathability.
-Kev siv: khoom siv kho mob, khaub ncaws pov tseg, khoom siv hauv tsev, thiab lwm yam.
Muaj qhov sib txawv tseem ceeb hauv microstructure ntawm non-woven fabrics uas tsim los ntawm spunbond (sab laug) thiab cov txheej txheem meltblown ntawm tib lub teev. Nyob rau hauv txoj kev spunbond, cov fibers thiab fiber ntau qhov khoob yog loj dua cov uas ua los ntawm txoj kev meltblown. Qhov no kuj yog vim li cas meltblown non-woven fabrics nrog me me fiber ntau qhov chaw raug xaiv rau cov ntaub tsis-woven hauv lub qhov ncauj qhov ntswg.
