Lo lus nonwoven txhais tau tias tsis yog "woven" lossis "knit", tab sis cov ntaub yog ntau dua.Non-woven yog cov qauv textile uas ncaj qha tsim los ntawm fibers los ntawm kev sib txuas los yog kev sib txuas los yog ob qho tib si.Nws tsis muaj cov qauv geometrical, es nws yog qhov tshwm sim ntawm kev sib raug zoo ntawm ib leeg thiab lwm tus.Cov hauv paus ntsiab lus ntawm nonwovens tej zaum yuav tsis meej tab sis lo lus "nonwoven fabrics" yog coined nyob rau hauv 1942 thiab tau tsim nyob rau hauv lub tebchaws United States.
Non-woven fabrics yog ua nyob rau hauv 2 txoj kev tseem ceeb: lawv yog felted los yog lawv yog bonded.Felted non-woven npuag yog tsim los ntawm txheej txheej nyias, tom qab ntawd siv cov cua sov, noo noo & siab kom ntsws & compress cov fibers rau hauv daim ntaub tuab matted uas yuav tsis ravel lossis fray.Ib zaug ntxiv, muaj 3 txoj hauv kev tseem ceeb ntawm kev tsim cov khoom siv tsis-woven: qhuav Laid, ntub dej & Direct spun.Nyob rau hauv Dry Laid Non-woven Fabric manufacturing process, ib lub vev xaib ntawm cov fibers tau muab tso rau hauv lub nruas thiab cov cua kub yog txhaj rau cov fibers ua ke.Nyob rau hauv cov txheej txheem ntawm Wet-Laid Non-woven Fabric manufacturing txheej txheem, lub vev xaib ntawm cov fibers yog tov nrog cov kuab tshuaj softening uas tso tawm cov kua nplaum zoo li cov khoom uas khi cov fibers ua ke thiab tom qab ntawd lub vev xaib tau muab tso rau kom qhuav.Nyob rau hauv Direct Spun Non-woven Fabric manufacturing process, cov fibers yog spun rau ib txoj siv conveyer thiab cov nplaum yog txau rau ntawm cov fibers, uas tom qab ntawd nias rau daim ntawv cog lus.(Thaum cov thermoplastic fibers, kua nplaum tsis tas yuav tsum tau.)
Cov khoom siv tsis-woven
Txhua qhov chaw koj zaum lossis sawv tam sim no, tsuas yog them nyiaj saib ib puag ncig thiab surly koj yuav pom tsawg kawg ib daim ntaub tsis-woven.Nonwoven fabrics nkag mus rau ntau yam kev lag luam nrog rau kev kho mob, khaub ncaws, tsheb, pom, kev tsim kho, geotextiles thiab tiv thaiv.Ib hnub dhau ib hnub kev siv cov ntaub tsis-woven yog nce thiab tsis muaj lawv peb lub neej tam sim no yuav dhau los ua qhov tsis nkag siab.Yeej muaj 2 hom nonwoven ntaub: Durable & pov tseg.Nyob ib ncig ntawm 60% ntawm cov ntaub nonwoven yog ruaj thiab so 40% yog pov tseg.
Ob peb Innovation hauv Non-woven Industry:
Kev lag luam tsis-woven yog ib txwm ua kom muaj txiaj ntsig nrog lub sijhawm xav tau kev tsim kho tshiab thiab qhov no tseem pab txhawb kev lag luam.
Surfaceskins (Nonwovens Innovation & Research Institute- NIRI): Nws yog cov tshuaj tua kab mob lub qhov rooj thawb cov ntaub qhwv & rub cov tes uas tau tsim los tua cov kab mob & cov kab mob hauv lub vib nas this tseem ceeb, ntawm ib tus neeg siv thiab lwm tus dhau los ntawm lub qhov rooj.Yog li nws pab tiv thaiv kev kis kab mob thiab kab mob ntawm cov neeg siv.
Reicofil 5 (Reifenhäuser Reicofil GmbH & Co. KG): Lub tshuab no muab cov tshuab ua haujlwm zoo tshaj plaws, txhim khu kev qha thiab siv tau zoo uas txo cov khoom nyuaj los ntawm 90 feem pua;nce cov zis mus txog 1200 m / min;streamlines lub sij hawm txij nkawm;txo lub zog noj.
Remodelling ™ Compound Hernia Patch (Shanghai Pine & Fais Fab Biotech): Nws yog ib qho electro-spun nano-scale thaj uas yog tus nqi-zoo absorbable biological graft thiab pab raws li ib tug loj hlob nruab nrab ntawm cov hlwb tshiab, thaum kawg biodegrading;txo tus nqi ntawm cov teeb meem tom qab kev ua haujlwm.
Kev thov thoob ntiaj teb:
Tuav yuav luag ib lub sijhawm tsis sib haum xeeb ntawm kev loj hlob dhau 50 xyoo dhau los, nonwoven tuaj yeem yog lub hnub tuaj ntawm kev lag luam textile thoob ntiaj teb nrog cov nyiaj tau los ntau dua li lwm yam khoom siv textile.Kev ua lag luam thoob ntiaj teb ntawm cov ntaub tsis-woven yog coj los ntawm Tuam Tshoj nrog kev lag luam sib koom ntawm ib puag ncig 35%, tom qab ntawd Europe nrog kev lag luam ntawm ib ncig ntawm 25%.Cov neeg ua si hauv kev lag luam no yog AVINTIV, Freudenberg, DuPont thiab Ahlstrom, qhov twg AVINTIV yog cov chaw tsim khoom loj tshaj plaws, nrog rau cov khoom lag luam feem ntau ntawm 7%.
Nyob rau lub sijhawm tsis ntev los no, nrog kev nce ntawm KEVIC-19, kev thov kev nyiam huv & 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 mus txog 10x rau 30x nyob rau hauv txawv teb chaws.
Raws li tsab ntawv ceeb toom ntawm lub ntiaj teb loj tshaj plaws kev lag luam tshawb fawb khw "Kev Tshawb Fawb & Kev Lag Luam", Kev Lag Luam Thoob Ntiaj Teb Nonwoven Fabrics suav txog $ 44.37 billion hauv 2017 thiab xav tias yuav ncav cuag $ 98.78 nphom los ntawm 2026, loj hlob ntawm CAGR ntawm 9.3% thaum lub sijhawm kwv yees.Nws kuj tseem xav tias kev lag luam tsis-woven ruaj yuav loj hlob nrog tus nqi CAGR siab dua.
Vim li cas Tsis-Woven?
Nonwovens yog cov tshiab, muaj tswv yim, ntau yam, siv tshuab siab, hloov tau, qhov tseem ceeb thiab decomposable.Hom ntaub no ncaj qha ua los ntawm fibers.Yog li tsis tas yuav tsum tau npaj cov txheej txheem xov paj.Cov txheej txheem tsim khoom yog luv & yooj yim.Qhov twg los tsim 5,00,000 meters ntawm woven npuag, nws yuav siv sij hawm ib ncig ntawm 6 lub hlis (2 lub hlis rau cov xov paj npaj, 3 lub hlis rau weaving ntawm 50 looms, 1 lub hlis rau xov & tshuaj xyuas), nws yuav siv sij hawm tsuas yog 2 lub hlis los tsim ib tug ntau npaum ntawm non-woven npuag.Yog li ntawd, qhov ntau lawm tus nqi ntawm woven npuag yog 1 mete / feeb thiab ntau lawm tus nqi ntawm knit fabric yog 2 meter / feeb, tab sis tus nqi ntau lawm ntawm non-woven npuag yog 100 meter / feeb.Ntxiv mus, tus nqi tsim khoom yog tsawg.Tsis tas li ntawd, cov ntaub nonwoven nthuav tawm cov khoom tshwj xeeb xws li lub zog siab dua, ua pa, nqus tau, ua haujlwm ntev, lub teeb yuag, hluav taws kub hnyiab, pov tseg thiab lwm yam. Vim tias tag nrho cov yam ntxwv zoo kawg li, textile sector yog txav mus rau cov ntaub tsis-woven.
Xaus:
Cov ntaub tsis-woven feem ntau hais tias yog yav tom ntej ntawm kev lag luam textile raws li lawv qhov kev thov thoob ntiaj teb & kev siv ntau yam tsuas yog nce siab & siab dua.
