Cov xov tsis-ntaub yog cov ntaub -zoo li cov khoom siv ua los ntawm cov khoom siv fiber ntau (luv) thiab ntev fiber ntau (txuas ntxiv ntev), sib koom ua ke los ntawm tshuaj lom neeg, tshuab, kub lossis tshuaj kho. Lo lus yog siv rau hauv kev lag luam textile manufacturing los txhais cov ntaub, xws li muaj kev sib tw , uas tsis yog tus twg tsis xaws los yog xaws . Qee cov ntaub ntawv tsis muaj ntaub qhwv tsis muaj lub zog txaus tshwj tsis yog densified lossis txhawb nqa los ntawm thim rov qab. Nyob rau hauv xyoo tas los, tsis-woven tau dhau los ua lwm txoj rau polyurethane ua npuas ncauj.
Non-woven fabrics yog qhov dav txhais tau hais tias yog daim ntawv lossis web qauv sib khi ua ke los ntawm entangling fiber los yog filaments (thiab los ntawm perforating zaj duab xis) mechanically, thermally lossis chemically. Lawv yog cov tiaj tiaj lossis tufted ntxeem tau cov ntawv uas tau tsim ncaj qha los ntawm nyias cov nyias ua nyias, molten yas lossis yas zaj duab xis. Lawv tsis yog ua los ntawm kev xaws los yog xaws thiab tsis tas yuav hloov lub xov rau cov xov paj. Feem ntau, qee qhov feem pua ntawm cov ntaub ntawv rov ua dua tshiab thiab cov roj-cov khoom siv yog siv hauv cov ntawv tsis-qhwv. Qhov feem pua ntawm cov khoom siv rov ua dua tshiab sib txawv raws li lub zog ntawm cov khoom uas xav tau rau qhov siv tshwj xeeb. Tsis tas li ntawd, qee qhov ntaub ntawv tsis-woven tuaj yeem rov ua dua tom qab siv, muab cov kev kho mob thiab chaw kho kom zoo. Vim li no, qee qhov xav txog cov ntaub ntawv tsis muaj ntaub qhwv ntau dua rau qee yam kev siv, tshwj xeeb hauv cov teb thiab kev lag luam uas cov khoom siv pov tseg lossis cov khoom siv ib qho tseem ceeb, xws li tsev kho mob, tsev kawm ntawv, tsev laus thiab chaw nyob kom zoo.
Cov xov tsis-xaws tau tsim muaj kev ua qauv siv uas yog kev siv ib zaug, muaj kev txwv lub neej, lossis siv tau ntev heev. Cov ntaub qhwv tsis muaj txheej txheem muab cov haujlwm tshwj xeeb xws li kev nqus, ua kua pleev xim, tiv taus, ncab, muag muag, lub zog, nplaim taws rov qab, ntxuav kom zoo nkauj, cushioning, thermal rwb thaiv tsev, acoustic rwb thaiv tsev, pom, siv raws li cov kab mob thiab tsis haum. Cov khoom no feem ntau ua ke los tsim cov khaub ncaws kom haum rau cov haujlwm tshwj xeeb, thaum ua tiav cov txiaj ntsig zoo ntawm kev siv khoom-lub neej thiab tus nqi. Lawv tuaj yeem qog cov yam ntxwv, kev ntxhib los mos thiab lub zog ntawm ib txoj phuam uas tuab thiab tuaj yeem ua qhov loj xws li cov kab ntau tshaj. Ua ke nrog lwm cov ntaub ntawv lawv muab cov spectrum ntawm cov khoom uas muaj cov khoom sib txawv, thiab siv nyob ib leeg los yog cov khoom siv xws li khaub ncaws, khoom vaj khoom tsev, kev saib xyuas kev noj qab haus huv, engineering, kev lag luam thiab cov khoom lag luam.
