Kev lag luam tsim khoom ntawm nonwovens tau nyob ib ncig ntawm ze li ib puas xyoo.Kev lag luam tsim khoom ntawm cov ntaub tsis-woven hauv kev xav niaj hnub pib tshwm sim hauv xyoo 1878, thaum lub tuam txhab British William Bywater tau ua tiav lub koob punching tshuab hauv ntiaj teb.
Kev tsim khoom niaj hnub tiag tiag ntawm kev lag luam nonwovens tsuas yog pib tom qab Tsov Rog Ntiaj Teb Zaum Ob.Thaum kawg ntawm kev ua tsov ua rog, lub ntiaj teb yog nyob rau hauv kev puas tsuaj, thiab kev thov rau ntau yam textiles yog nce.
Raws li qhov xwm txheej no, nonwovens tau tsim sai heev thiab tau dhau los ntawm plaub theem txog tam sim no:
1. Lub sij hawm budding yog los ntawm thaum ntxov 1940s mus rau nruab nrab-1950s.Feem ntau ntawm cov tuam txhab textile tau siv cov cuab yeej tiv thaiv npaj ua kom tsim nyog thiab siv cov fibers ntuj los tsim cov ntaub ntawv tsis-woven.
Lub sijhawm no, tsuas yog ob peb lub tebchaws xws li Tebchaws Meskas, Lub Tebchaws Yelemees thiab Tebchaws Askiv tau tshawb nrhiav thiab tsim cov ntaub tsis-woven, thiab lawv cov khoom yog cov tuab thiab tuab zoo li cov ntaub tsis-woven.
Thib ob, lub sijhawm ua lag luam tsim khoom yog los ntawm qhov kawg ntawm xyoo 1950 mus rau qhov kawg ntawm xyoo 1960.Lub sijhawm no, kev siv tshuab ziab khaub ncaws thiab cov tshuab ntub dej feem ntau yog siv, thiab cov tshuaj fiber ntau yog siv los tsim cov ntaub ntawv tsis-woven.
3. Lub sijhawm tseem ceeb ntawm txoj kev loj hlob, txij li thaum ntxov 1970s mus rau lig 1980s, lub sij hawm no, ib tug ua tiav cov kab ntau lawm rau polymerization thiab extrusion txoj kev tau yug los.
Txoj kev loj hlob sai ntawm ntau yam tshwj xeeb nonwoven tshwj xeeb fibers, xws li qis melting point fibers, thermal bonding fibers, bicomponent fibers, ultrafine fibers, thiab lwm yam., tau sai txhawb txoj kev loj hlob ntawm nonwoven cov ntaub ntawv kev lag luam.
Lub sijhawm no, lub ntiaj teb nonwoven ntau lawm mus txog 20,000 tons thiab cov khoom tsim tawm tau tshaj 200 lab US dollars.
Qhov no yog ib qho kev lag luam tawm tshiab raws li kev koom tes ntawm petrochemical, yas tshuaj, tshuaj zoo, ntawv kev lag luam thiab textile kev lag luam.Nws yog lub npe hu ua lub hnub sawv kev lag luam hauv kev lag luam textile. "daim ntawv thov.
4.Rau lub hauv paus ntawm kev loj hlob tsis tu ncua ntawm cov ntaub ntawv tsis-woven, cov tshuab tsis-woven npuag tau ua ntau yam kev vam meej nyob rau tib lub sijhawm, uas tau nyiam thoob ntiaj teb kev saib xyuas, thiab thaj tsam ntawm cov khoom tsis-woven. ntaub kuj tau nthuav dav heev.
Plaub, lub sijhawm kev loj hlob thoob ntiaj teb, txij li thaum ntxov 1990s txog rau tam sim no, cov lag luam uas tsis yog-woven tau tsim los ntawm leaps thiab ciam teb.
Los ntawm kev siv thev naus laus zis ntawm cov khoom siv, kev ua kom zoo ntawm cov qauv khoom, cov cuab yeej ntse, thiab kev lag luam branding, thiab lwm yam., cov tshuab tsis-woven tau dhau los ua ntau dua thiab paub tab, cov cuab yeej tau dhau los ua cov khoom lag luam, kev ua haujlwm ntawm cov ntaub ntawv tsis-woven thiab cov khoom muaj. tau txais kev txhim kho zoo, thiab lub peev xwm ntau lawm thiab cov khoom lag luam tau txuas ntxiv nthuav dav.Cov khoom siv tshiab, thev naus laus zis tshiab, thiab cov ntawv thov tshiab tshwm sim ib qho tom qab.
Nyob rau lub sijhawm no, thev naus laus zis ntawm spin-forming thiab melt-blown nonwovens tau nrawm nrawm thiab siv rau hauv kev tsim khoom, thiab cov tuam txhab tsim khoom kuj tau tsim ua tiav cov txheej txheem ntawm spin-forming thiab yaj-blown nonwoven cov kab ntau lawm rau kev ua lag luam.
Cov tshuab drylaid nonwovens kuj tau ua tiav tseem ceeb hauv lub sijhawm no.
