Kupanga kwa mafakitale kwa nsalu zopanda nsalu zakhala zikuchitika kwa zaka pafupifupi 100.Kupanga mafakitale a nsalu zopanda nsalu m'lingaliro lamakono kunayamba kuonekera mu 1878, ndipo kampani ya ku Britain William Bywater inapanga makina opambana a singano padziko lapansi.Zowona zenizeni zopanda nsalu zamakono zopanga mafakitale zidayamba pambuyo pa Nkhondo Yachiwiri Yapadziko Lonse, kumapeto kwa nkhondoyo, zinyalala zapadziko lonse lapansi zikudikirira kuwuka, kufunikira kwa nsalu zosiyanasiyana kukukula.Pankhaniyi, nsalu zosalukidwa zidakula mwachangu, mpaka pano zakhala ndi magawo anayi:
Choyamba, nthawi ya embryonic, ndi kumayambiriro kwa zaka za m'ma 1940-50s, mabizinesi ambiri a nsalu amagwiritsa ntchito zipangizo zodzitetezera pa alumali, kusintha koyenera, kugwiritsa ntchito ulusi wachilengedwe kupanga zinthu zopanda nsalu.Panthawi imeneyi, kokha United States, Germany ndi United Kingdom ndi mayiko ena ochepa mu kafukufuku ndi kupanga nsalu sanali nsalu, mankhwala ake makamaka wandiweyani wadding kalasi ya nsalu sanali nsalu.Chachiwiri, nthawi yopangira malonda ndi kumapeto kwa zaka za m'ma 1950-kumapeto kwa zaka za m'ma 1960, panthawiyi makamaka pogwiritsa ntchito teknoloji yowuma komanso teknoloji yonyowa, pogwiritsa ntchito ulusi wambiri wamankhwala kuti apange zopanda nsalu.
Chachitatu, nthawi yofunika yachitukuko, kumayambiriro kwa zaka za m'ma 1970-mochedwa m'ma 1980, panthawiyi polymerization, extrusion yathunthu ya mizere yopanga anabadwa.Kukula kofulumira kwa ulusi wapadera wosalukitsidwa, monga ulusi wochepa wosungunuka, ulusi wolumikizana ndi kutentha, ulusi wa bicomponent, ulusi wapamwamba kwambiri, ndi zina zambiri.Panthawi imeneyi, kupanga padziko lonse nonwovens anafika matani 20,000, linanena bungwe mtengo wa madola oposa 200 miliyoni US.Iyi ndi mafakitale atsopano okhudzana ndi mgwirizano pakati pa petrochemical, mankhwala apulasitiki, mankhwala abwino, opanga mapepala ndi mafakitale a nsalu, omwe amadziwika kuti sunrise industry m'makampani a nsalu, malonda ake akhala akugwiritsidwa ntchito kwambiri m'magawo osiyanasiyana a chuma cha dziko.Pamaziko a kukula kofulumira kwa kupanga ma nonwovens, ukadaulo wa nonwovens wapita patsogolo kwambiri, zomwe zakopa chidwi cha dziko lapansi, ndipo gawo lopangira zinthu zopanda nsalu lakulanso mwachangu.Chachinayi, nthawi yachitukuko chapadziko lonse lapansi, koyambirira kwa 1990 mpaka pano, mabizinesi omwe sialukidwa akhala akutukuka kwambiri.Kudzera luso luso zida, kukhathamiritsa kwa dongosolo mankhwala, luntha zida ndi chizindikiro msika, teknoloji nonwoven amakhala patsogolo ndi okhwima, zipangizo amakhala apamwamba kwambiri, zipangizo nonwoven ndi ntchito mankhwala bwino kwambiri, mphamvu kupanga ndi mndandanda mankhwala kupitiriza kukula, latsopano mankhwala, matekinoloje atsopano ndi ntchito zatsopano zimatuluka chimodzi ndi china.
