Non-woven fabric yog ib hom khoom siv textile uas yog tsim los ntawm kev sib txuas los yog kev sib txuas fiber ntau ua ke es tsis yog xaws los yog knitting ua ke. Cov txheej txheem kev sib txuas no tuaj yeem ua tiav los ntawm ntau txoj hauv kev, suav nrog kev siv tshuab, tshuaj lom neeg, thermal, lossis hnyav bonding. Non-woven fabrics yog tsim los ntawm fibers uas yuav ua tau ntuj (xws li paj rwb, ntaub plaub, los yog txhob lo lo ntxhuav) los yog hluavtaws (xws li polyester, polypropylene, los yog nylon).
Muaj ob peb yam ntxwv uas txhais cov ntaub tsis-woven:
Tsis muaj xov paj los yog xov: Tsis zoo li cov ntaub woven, uas yog tsim los ntawm interlacing yarns los yog threads, non-woven fabrics yog tsim ncaj qha los ntawm fibers uas yog bonded ua ke.
Random Fiber Orientation: Cov fibers hauv cov ntaub tsis-woven feem ntau yog teem caij los yog nyob rau hauv ib qho kev taw qhia kom ua tiav cov khoom xav tau xws li lub zog, absorbency, los yog pom.
Porosity: Cov ntaub tsis-woven feem ntau muaj cov qauv ntxeem tau uas tso cai rau huab cua, kua, lossis roj nkag mus. Lub porosity ntawm cov ntaub tsis-woven tuaj yeem tswj tau thaum lub sijhawm tsim khoom kom ua tiav cov qib tshwj xeeb ntawm breathability lossis pom.
Flexibility thiab Drape: Cov ntaub tsis-woven tuaj yeem sib txawv hauv qhov yooj yim thiab cov ntaub ntaub nyob ntawm seb hom thiab kev npaj ntawm fibers siv. Qee cov ntaub tsis-woven yog tawv thiab nruj, thaum lwm tus yog mos thiab hloov tau.
Kev siv ntau yam: Cov ntaub tsis-woven yog siv ntau yam kev siv, suav nrog cov khoom siv kho mob thiab phais (xws li lub ntsej muag phais thiab lub tsho), cov khoom siv tu cev (xws li cov pawm thiab cov ntaub so), pom cov xov xwm, tsheb sab hauv, geotextiles, thiab khoom siv.
Piv txwv ntawm non-woven fabrics muaj xws li:
Spunbond non-woven npuag: Ua los ntawm extruding nruam filaments ntawm hluavtaws fibers thiab ces khi lawv ua ke.
Meltblown non-woven npuag: Ua los ntawm extruding molten polymer los ntawm cov zoo nozzles thiab ces tshuab cov fibers mus rau ib tug collector screen los tsim ib tug random web.
Koob punched non-woven npuag: Ua los ntawm mechanically entangling fibers nrog barbed koob.
Cov ntaub ntub dej tsis-woven: Ua los ntawm kev tshem tawm cov fibers hauv dej, tsim lub vev xaib ntawm lub vijtsam, thiab tom qab ntawd txuas cov fibers ua ke nrog kev sib ntxiv ntawm cov ntawv khi.
Non-woven fabrics muaj qhov zoo xws li tus nqi-zoo, versatility, thiab muaj peev xwm ua kom haum rau cov khoom siv tshwj xeeb. Lawv tau siv dav hauv ntau qhov kev lag luam thiab txuas ntxiv mus nrhiav cov ntawv thov tshiab raws li kev siv thev naus laus zis.
