Lo lus nonwoven txhais tau tias tsis yog "woven" lossis "knit", tab sis cov ntaub yog ntau ntxiv. Non-woven yog cov qauv textile uas tsim los ntawm cov fibers los ntawm kev sib txuas lossis sib txuas lossis ob qho tib si. Nws tsis muaj cov qauv geometrical, es nws yog qhov tshwm sim ntawm kev sib raug zoo ntawm ib qho fiber thiab lwm qhov. Cov hauv paus tseeb ntawm nonwovens tej zaum yuav tsis meej tab sis lo lus "nonwoven fabrics" tau tsim nyob rau hauv xyoo 1942 thiab tau tsim nyob rau hauv Tebchaws Meskas.
Cov ntaub tsis-woven yog ua los ntawm 2 txoj kev tseem ceeb: lawv yog felted lossis lawv tau sib txuas. Cov ntaub tsis-woven felted yog tsim los ntawm kev txheej nyias nyias, tom qab ntawd siv cua sov, dej noo & siab kom ntsws & nias cov fibers rau hauv daim ntaub tuab matted uas yuav tsis ravel lossis fray. Dua li muaj 3 txoj hauv kev tseem ceeb ntawm kev tsim cov ntaub tsis-woven sib txuas: Qhuav Laid, Wet Laid & Direct Spun. Hauv cov txheej txheem tsim khoom Qhuav Laid Non-woven Fabric, lub vev xaib ntawm cov fibers raug tso rau hauv lub nruas thiab cua kub raug txhaj tshuaj kom sib txuas cov fibers ua ke. Hauv cov txheej txheem tsim khoom Wet-Laid Non-woven Fabric, lub vev xaib ntawm cov fibers yog sib xyaw nrog cov kuab tshuaj softening uas tso tawm cov khoom zoo li kua nplaum uas sib txuas cov fibers ua ke thiab tom qab ntawd lub vev xaib raug tso tawm kom qhuav. Hauv cov txheej txheem tsim khoom Direct Spun Non-woven Fabric, cov fibers raug tig rau ntawm txoj siv sia thiab cov kua nplaum raug txau rau ntawm cov fibers, uas tom qab ntawd nias kom sib txuas. (Hauv cov ntaub ntawv ntawm cov thermoplastic fibers, kua nplaum tsis tas yuav tsum muaj.)
Cov Khoom Uas Tsis Yog Xov
Txawm koj zaum lossis sawv ntsug li cas los xij, tsuas yog saib ib ncig thiab koj yuav pom tsawg kawg ib daim ntaub tsis-woven. Cov ntaub tsis-woven nkag mus rau ntau yam kev lag luam suav nrog kev kho mob, khaub ncaws, tsheb, lim dej, kev tsim kho, geotextiles thiab kev tiv thaiv. Txhua hnub kev siv cov ntaub tsis-woven nce ntxiv thiab yog tsis muaj lawv peb lub neej tam sim no yuav dhau los ua qhov tsis nkag siab. Yeej muaj 2 hom ntaub tsis-woven: Durable & Disposal. Kwv yees li 60% ntawm cov ntaub tsis-woven yog cov khoom siv ruaj khov thiab so 40% yog pov tseg.
Ob Peb Txoj Kev Tsim Kho Tshiab Hauv Kev Lag Luam Tsis-woven:
Kev Lag Luam Tsis-woven yeej ib txwm nplua nuj nrog cov kev hloov pauv uas xav tau lub sijhawm thiab qhov no kuj pab txhawb kev lag luam.
Cov tawv nqaij saum npoo (Lub Koom Haum Tsim Kho Tshiab & Tshawb Fawb Tsis-wovens- NIRI): Nws yog cov ntaub thaiv qhov rooj uas thawb thiab rub cov tes tuav uas tau tsim los tua cov kab mob thiab cov kab mob uas tau tso rau hauv vib nas this tseem ceeb, ntawm ib tus neeg siv thiab tus neeg tom ntej uas hla lub qhov rooj. Yog li nws pab tiv thaiv kev kis tus kab mob thiab cov kab mob ntawm cov neeg siv.
Reicofil 5 (Reifenhäuser Reicofil GmbH & Co. KG): Cov thev naus laus zis no muab cov kab tsim khoom zoo tshaj plaws, txhim khu kev qha thiab ua haujlwm tau zoo uas txo cov khoom tawv los ntawm 90 feem pua; nce cov zis tawm mus txog 1200 m / min; ua kom lub sijhawm txij nkawm yooj yim dua; txo kev siv hluav taws xob.
Remodelling™ Compound Hernia Patch (Shanghai Pine & Power Biotech): Nws yog ib daim electro-spun nano-scale patch uas yog ib qho khoom siv biologic graft uas pheej yig heev thiab tuaj yeem nqus tau thiab ua haujlwm ua ib qho chaw loj hlob rau cov cell tshiab, thaum kawg biodegrading; txo qhov nrawm ntawm cov teeb meem tom qab phais.
Kev Xav Tau Thoob Ntiaj Teb:
Tau 50 xyoo dhau los no, cov ntaub tsis yog woven tau loj hlob zoo heev, thiab qhov no yog qhov tseem ceeb tshaj plaws hauv kev lag luam textile thoob ntiaj teb. Tuam Tshoj yog tus thawj coj hauv kev lag luam nrog rau feem ntawm kev ua lag luam li ntawm 35%, tom qab ntawd yog Tebchaws Europe nrog rau feem ntawm kev ua lag luam li ntawm 25%. Cov neeg ua si tseem ceeb hauv kev lag luam no yog AVINTIV, Freudenberg, DuPont thiab Ahlstrom, qhov twg AVINTIV yog lub tuam txhab tsim khoom loj tshaj plaws, nrog rau feem ntawm kev ua lag luam li ntawm 7%.
Nyob rau lub sijhawm tsis ntev los no, nrog rau kev nce ntxiv ntawm cov neeg mob COVIC-19, qhov kev thov rau kev tu cev thiab cov khoom siv kho mob ua los ntawm cov ntaub tsis-woven (xws li: lub kaus mom phais, lub ntsej muag phais, PPE, apron kho mob, khau npog thiab lwm yam) tau nce txog li 10x txog 30x hauv ntau lub tebchaws.
Raws li daim ntawv tshaj tawm ntawm lub khw tshawb fawb kev lag luam loj tshaj plaws hauv ntiaj teb "Kev Tshawb Fawb & Kev Lag Luam", Kev lag luam thoob ntiaj teb Nonwoven Fabrics muaj nqis txog $ 44.37 billion hauv xyoo 2017 thiab xav tias yuav ncav cuag $ 98.78 billion los ntawm xyoo 2026, loj hlob ntawm CAGR ntawm 9.3% thaum lub sijhawm kwv yees. Nws kuj xav tias kev lag luam ruaj khov tsis-woven yuav loj hlob nrog tus nqi CAGR siab dua.
Vim li cas thiaj xaiv Non-Woven?
Cov ntaub tsis yog woven yog cov khoom tshiab, muaj tswv yim, siv tau ntau yam, siv thev naus laus zis siab, hloov tau yooj yim, tseem ceeb thiab lwj tau. Hom ntaub no yog tsim los ntawm cov fibers ncaj qha. Yog li ntawd, tsis tas yuav muaj cov kauj ruam npaj xov paj. Cov txheej txheem tsim khoom luv luv thiab yooj yim. Qhov twg los tsim 5,00,000 meters ntawm cov ntaub woven, nws siv sijhawm li 6 lub hlis (2 lub hlis rau kev npaj xov paj, 3 lub hlis rau kev xaws ntawm 50 lub looms, 1 lub hlis rau kev ua tiav & kev tshuaj xyuas), nws tsuas yog siv sijhawm 2 lub hlis los tsim cov ntaub tsis yog woven tib yam. Yog li ntawd, qhov twg qhov nrawm ntawm cov ntaub woven yog 1 mete / feeb thiab qhov nrawm ntawm cov ntaub knitted yog 2 meter / feeb, tab sis qhov nrawm ntawm cov ntaub tsis yog woven yog 100 meter / feeb. Ntxiv mus, tus nqi tsim khoom qis. Tsis tas li ntawd, cov ntaub tsis yog woven qhia txog cov yam ntxwv tshwj xeeb xws li lub zog siab dua, ua pa tau, nqus tau, ruaj khov, lub teeb yuag, qeeb hluav taws, pov tseg tau thiab lwm yam. Vim yog tag nrho cov yam ntxwv zoo kawg no, kev lag luam textile tab tom txav mus rau cov ntaub tsis yog woven.
Xaus lus:
Cov ntaub tsis-woven feem ntau hais tias yog yav tom ntej ntawm kev lag luam textile vim lawv qhov kev thov thoob ntiaj teb & kev hloov pauv tau tsuas yog nce siab & siab dua.
