Non-woven fabrics tsis muaj interwoven strands, tab sis muaj ib tug txheej txheem sab hauv. Cov ntaub no yog tsim los ntawm kev muab cov fibers ua ke thiab muab tso rau hauv cov ntaub nplaum zoo li cov khoom siv nrog cua sov, chemistry lossis siab. Contrary to tsoos cov ntaub ntawv, xws li paj rwb, linen, ntaub plaub thiab txhob lo lo ntxhuav; Non-woven fabrics tsis tas yuav xaws los yog weave xav, uas yog ib qho ntawm feem ntau piv txwv ntawm non-woven fabrics. Nws yog tsim los ntawm nplawm cov fibers hauv kev daws kom txog thaum lawv sib cuam tshuam rau hauv cov ntaub ntom ntom.
Muaj ntau cov ntaub ntawv tsis-woven, uas feem ntau txhais los ntawm txoj kev sib txuas ntawm fiber ntau ua ke: mechanical bonding (filament winding), chemical bonding (fibers are chemically bonded together by glue like compounds) los yog thermal bonding (tsis tshua muaj melting point fibers. thiab cov fibers yaj ib leeg los ntawm cua sov). Cov ntaub fabrics muaj me ntsis nyob rau hauv ntau tsuas yog hais tias lawv raug cais raws li nonwovens. Nonwoven Cheebtsam, xws li:; Kev xaiv fiber ntau, tsim lub vev xaib, kev sib txuas thiab kev ua tiav tuaj yeem hloov pauv mus rau kev tswj cov khoom siv los yog thim rov qab engineer fabrics raws li kev ua haujlwm.
Txawm hais tias nws tuaj yeem hais tau tias qee cov ntaub ntawv tsis-woven tuaj yeem pom hauv qhov xwm txheej, xws li kab laug sab webs, cocoons thiab noog zes, thawj pawg ntawm cov ntaub tsis-woven tau pib siv hauv kev tsim khoom hauv xyoo 1940.
Nonwovens yog sib dua thiab tsis muaj zog tshaj woven los yog knitted fabrics. Raws li cov khoom siv, cov khoom siv tsis-woven muaj kev nco tsis zoo thiab kev ntxuav tsis zoo, yog li nws tsis haum rau kev tsim cov khaub ncaws ruaj khov. Feem ntau cov ntaub tsis-woven yog siv rau kev siv pov tseg. Txawm li cas los xij, xav txog kev siv ntau yam thiab cov nqi tsim khoom tsawg ntawm cov khoom siv nonwovens, kev siv cov nonwovens kuj muaj qhov zoo.
Non-woven fabrics yog siv dav hauv kev lag luam sib txawv. Hauv kev lag luam kev kho mob, cov ntaub tsis-woven tsim cov khaub ncaws cais tawm, cov khaub ncaws phais thiab ntim khoom kho mob. Hauv kev lag luam ntaub pua plag, lawv tau siv los ua cov ntaub pua plag. Nws cov yam ntxwv kuj tau siv dav hauv kev ua liaj ua teb, kev tsim kho, tsheb thiab lwm yam lag luam.
Nyob rau hauv cov nqe lus ntawm kev zam, cov ntaub uas tsis yog-woven yog siv los tsim cov ntaub hauv ob sab phlu, rwb thaiv tsev thiab tiv thaiv khaub ncaws, khaub ncaws ua haujlwm, tshuaj tiv thaiv khaub ncaws, khau, thiab lwm yam.
