Kupanga kwa mafakitale a nonwovens kwakhalapo kwa zaka pafupifupi zana.Kupanga kwa mafakitale kwa nsalu zopanda nsalu m'lingaliro lamakono kunayamba kuonekera mu 1878, pamene kampani ya ku Britain William Bywater inapanga bwino makina okhomerera singano padziko lapansi.
Zopanga zenizeni zamakono zamakampani a nonwovens zidangoyamba pambuyo pa Nkhondo Yachiwiri Yapadziko Lonse.Kumapeto kwa nkhondo, dziko lawonongeka, ndipo kufunika kwa nsalu zosiyanasiyana kukuchulukirachulukira.
Pazifukwa izi, ma nonwovens adakula mwachangu ndipo adutsa magawo anayi mpaka pano:
1. Nthawi yophukira ndi kuyambira kuchiyambi kwa 1940 mpaka pakati pa 1950s.Mabizinesi ambiri opangira nsalu amagwiritsa ntchito zida zodzitetezera zomwe zidapangidwa kale kuti zisinthidwe moyenera ndikugwiritsa ntchito ulusi wachilengedwe kupanga zida zosalukidwa.
Panthawi imeneyi, maiko ochepa okha monga United States, Germany ndi United Kingdom anali kufufuza ndi kupanga nsalu zosalukidwa, ndipo zopangidwa zawo makamaka zinali zokhuthala ndi zokhuthala ngati nsalu zosalukidwa.
Chachiwiri, nthawi yopanga malonda ndi kuyambira kumapeto kwa zaka za m'ma 1950 mpaka kumapeto kwa zaka za m'ma 1960.Panthawiyi, teknoloji youma ndi teknoloji yonyowa imagwiritsidwa ntchito makamaka, ndipo ulusi wambiri wa mankhwala amagwiritsidwa ntchito popanga zinthu zopanda nsalu.
3. Nthawi yofunikira yachitukuko, kuyambira kumayambiriro kwa zaka za m'ma 1970 mpaka kumapeto kwa zaka za m'ma 1980, panthawiyi, mizere yambiri yopangira ma polymerization ndi extrusion inabadwa.
Kukula mwachangu kwa ulusi wapadera wapadera womwe siwowongoka, monga ulusi wosungunuka, ulusi wolumikizana ndi matenthedwe, ulusi wa bicomponent, ulusi wa ultrafine, ndi zina zotere, zalimbikitsa kupita patsogolo kwa mafakitale osawoka.
Panthawi imeneyi, kupanga padziko lonse lapansi kosaluka kunafika matani 20,000 ndipo mtengo wake unaposa madola 200 miliyoni aku US.
Ili ndi bizinesi yomwe ikubwera potengera mgwirizano wa petrochemical, mankhwala apulasitiki, mankhwala abwino, makampani opanga mapepala ndi mafakitale a nsalu.Amadziwika kuti ndi makampani opanga nsalu.ntchito.
4. Pamaziko a kukula kosalekeza kwa kupanga nsalu zosalukidwa, ukadaulo wosalukidwa wapita patsogolo kwambiri nthawi imodzi, zomwe zakopa chidwi padziko lonse lapansi, komanso malo opangira zosaluka. nsalu yakulanso mofulumira.
Chachinayi, nthawi yachitukuko chapadziko lonse lapansi, kuyambira koyambirira kwa 1990 mpaka pano, mabizinesi osalukitsidwa adapangidwa modumphadumpha.
Kupyolera mu luso laukadaulo la zida, kukhathamiritsa kwa kapangidwe kazinthu, zida zanzeru, komanso kuyika chizindikiro pamsika, ndi zina zambiri, ukadaulo wopanda nsalu wakhala wotsogola komanso wokhwima, zida zakhala zotsogola kwambiri, magwiridwe antchito azinthu zosalukidwa ndi zinthu zakhala. zakhala bwino kwambiri, ndipo mphamvu yopanga ndi mndandanda wazinthu zakhala zikukulitsidwa mosalekeza.Zatsopano, matekinoloje atsopano, ndi mapulogalamu atsopano amatuluka chimodzi ndi china.
Panthawiyi, ukadaulo wopangira ma spin-forming and melt-blown nonwovens walimbikitsidwa ndikugwiritsidwa ntchito mwachangu popanga, ndipo opanga makinawo akhazikitsanso mizere yonse yopangira ma spin-forming ndi kusungunula-kuwombedwa kosaluka pamsika.
Ukadaulo wa drylaid nonwovens nawonso udapita patsogolo kwambiri panthawiyi.
