Cov ntaub ntawv tseem ceeb ntawm ntawv, textiles thiab nonwovens feem ntau yog cellulose fibers.Qhov txawv ntawm peb cov khoom nyob rau hauv yuav ua li cas cov fibers ua ke.

Textiles, nyob rau hauv uas cov fibers tau tuav ua ke tsuas yog los ntawm mechanical entanglement (xws li weaving).

Daim ntawv, nyob rau hauv uas cellulose fibers yeej sib koom ua ke los ntawm qaug zog tshuaj hydrogen bonds.

- Hauv qhov sib piv, cov nonwovens tau sib koom ua ke hauv ib lossis ntau txoj hauv qab no:

- Muaj zog chemical bonding agent.Piv txwv li, hluavtaws cob, latex lossis hnyav.

Melting nyob ib sab fibers (thermal bonding).

-Random mechanical entanglement ntawm filaments.Piv txwv li: spinning lace bonding (xws li hydroentanglement), koob punching lossis stitch bonding.

Daim ntawv ntawm cov khoom tiav tsis-woven npuag yog raws li nram no:

- npog.Piv txwv li rau cov pawm.

- Geotextiles (geosynthetics).Piv txwv li, kom sib sau ua ke inclined ntiaj teb embankment los yog kom ntws dej hauv civil engineering.

- Daim ntawv tsim kho.Piv txwv li: ntoo ncej ru tsev, breathable ntawv (siv rau lub tsev phab ntsa), pem teb npog.

-Tyvek cov khoom.Piv txwv li, floppy disk bracket, hnab ntawv.

- lwm yam khoom.Piv txwv li: cov ntaub so ntub dej;Napkin;Cov tais diav;Tshuaj yej hnab;Hnav khaub ncaws;Kev kho mob (xws li phais lub tsho, daim npog qhov ncauj, lub kaus mom, khau npog, hnav lub qhov txhab);Cov lim dej (tsheb, khoom siv cua tshuab, thiab lwm yam);Roj teeb cais;Ntaub pua plag;Roj absorbent.

Txawm hais tias tsis-woven fabrics feem ntau suav hais tias yog cov khoom siv pov tseg, qhov tseeb, feem ntau ntawm lawv yog cov khoom siv ruaj khov.

Yuav siv cov nonwovens li cas?

Dhau li ntawm cov ntsiab lus yooj yim, cov ntaub tsim khoom siv no kuj qhib lub ntiaj teb tshiab rau txhua hom kev lag luam.

Cov ntaub ntawv tsis-woven tuaj yeem yog cov ntaub siv pov tseg nrog lub neej tsawg lossis cov ntaub siv tau ntev heev.Nonwoven fabrics muaj cov haujlwm tshwj xeeb, xws li absorbency, kua repellency, resilience, stretchability, softness, zog, nplaim retardancy, washability, cushioning, filterability, kab mob barrier thiab sterility.Cov yam ntxwv no feem ntau yog ua ke los tsim cov ntaub tsim nyog rau ib txoj haujlwm tshwj xeeb, thaum ua tiav qhov sib npaug zoo ntawm cov khoom siv lub neej thiab tus nqi.Lawv tuaj yeem ua raws li cov tsos, kev ntxhib los mos thiab lub zog ntawm cov ntaub, thiab tuaj yeem ua qhov loj li qhov tuab tshaj plaws.

Cov hauv qab no yog qee yam khoom uas tuaj yeem tau txais los ntawm kev siv nonwovens:

Kev nqus dej, cov kab mob thaiv, cushioning, nplaim retardancy, kua repellency, elasticity, softness, zog extension thiab washability.

Niaj hnub no, kev tsim kho tshiab ntawm nonwovens tau loj hlob sai nrog kev xav tau ntau ntxiv rau lawv, uas yuav luag muab qhov tsis muaj kev txwv rau ntau yam kev lag luam, suav nrog:

Kev ua liaj ua teb, npog, khaub ncaws hauv ob sab phlu, tsheb ru tsev, tsheb sab hauv, ntaub pua plag, civil engineering, fabrics, pov tseg cov pawm, hnab ntawv, tsev neeg thiab tus kheej cov ntaub ntub dej rau lub tsev ntim khoom, cov khoom siv tu cev, cov ntaub ntawv rwb thaiv tsev, cov khoom ntxhua khaub ncaws, cov khoom siv kho mob tsis muaj menyuam.
