Dab tsi yog Cov Piv Txwv Ntawm Cov Npuag Tsis-woven

Non-woven fabricsyog cov ntaub ntawv uas yog tsim los ntawm kev sib txuas los yog kev sib txuas fibers ua ke, tsis yog xaws los yog knitting. Cov ntaub no muaj ntau yam kev siv vim lawv cov khoom tshwj xeeb, xws li breathability, yooj, thiab durability. Nov yog qee qhov piv txwv ntawm non-woven fabrics:

Felt: Felt yog ib qho ntawm cov qauv qub tshaj plaws ntawm cov ntaub tsis-woven, ua los ntawm compressing thiab matting fibers ua ke. Nws yog feem ntau siv rau cov khoom siv tes ua, cov ntawv thov kev lag luam, thiab ua cov khoom siv hauv ob sab phlu.

Spunbond Nonwovens: Cov ntaub no yog tsim los ntawm extruding nruam filaments ntawm ib tug hluavtaws polymer, xws li polypropylene, thiab ces khi lawv ua ke. Spunbond nonwovens yog siv rau hauv ntau daim ntawv thov, nrog rau cov khoom siv tu cev, npog ua liaj ua teb, thiab ntim khoom.

Meltblown Nonwovens: Meltblown fabrics yog tsim los ntawm melting thermoplastic resin thiab extruding nws los ntawm me me nozzles los tsim microfibers. Cov microfibers no ces random nteg thiab sib koom ua ke los tsim cov ntaub nonwoven. Cov ntaub ntawv Meltblown feem ntau yog siv rau hauv cov qhov ncauj qhov ntswg kho mob thiab cov lim dej.

Needle-Punched Nonwovens: Hom nonwoven ntaub no yog tsim los ntawm mechanically interlocking fibers siv barbed koob. Koob-punched fabrics yog siv nyob rau hauv daim ntaub ntawv xws li geotextiles, automotive interiors, thiab felted ntaub pua plag.

Spunlace Nonwovens: Spunlace fabrics yog tsim los ntawm entangling fibers los ntawm high-pressure dej dav hlau. Cov txheej txheem no tsim cov ntaub nrog cov ntaub mos mos thiab zoo li cov ntaub. Spunlace nonwovens feem ntau siv rau hauv cov ntaub so ntswg kho mob, cov ntaub so ntswg ntawm lub ntsej muag, thiab cov ntaub so menyuam mos.

Airlaid Nonwovens: Airlaid fabrics yog tsim los ntawm dispersing fibers nyob rau hauv cov huab cua thiab ces khi lawv ua ke nrog kev pab los ntawm ib tug binding neeg sawv cev. Cov ntaub no yog siv rau hauv cov khoom xws li cov ntaub so ntswg nqus, cov khoom siv tu cev, thiab cov ntaub so ntswg.

Composite Nonwovens: Cov ntaub no muab ntau hom fibers thiab / lossis cov ntaub ntawv kom ua tiav cov yam ntxwv ua tau zoo. Piv txwv li, cov ntaub tsis sib xyaw ua ke yuav muaj cov txheej txheem ntawm cov khoom siv spunbond ua ke nrog cov txheej txheem yaj-tshuab rau kev txhim kho pom.

SMS (Spunbond-Meltblown-Spunbond): SMS yog cov ntaub ntawv uas tsis yog-woven feem ntau siv hauv cov khoom kho mob thiab tu cev. Nws muab cov khaubncaws sab nraud povtseg ntawm spunbond thiab yaj-tshuab cov ntaub ntawv kom ua tiav qhov sib npaug ntawm lub zog, thaiv lub zog, thiab ua pa.
