Kugadzirwa kwemaindasitiri kwemanonwovens kwave kuripo kweanoda kusvika zana remakore.Kugadzirwa kwemaindasitiri kwemachira asiri akarukwa mupfungwa yemazuva ano kwakatanga kuoneka muna 1878, apo kambani yeBritish William Bywater yakabudirira kugadzira muchina wekubaya tsono munyika.
Kugadzirwa kwemazuva ano kweiyo nonwovens indasitiri yakangotanga mushure meHondo Yenyika Yechipiri.Nekupera kwehondo, nyika yaparara, uye kudiwa kwemachira akasiyana kuri kuwedzera.
Pasi pemamiriro ezvinhu aya, nonwovens akakura nekukurumidza uye apfuura nematanho mana kusvika zvino:
1. Nguva yekutungira inobva mukutanga kwema1940 kusvika pakati pema1950.Mazhinji emabhizinesi emachira akashandisa akagadzirira-akagadzirwa ekudzivirira midziyo kuita shanduko yakakodzera uye kushandisa echisikigo fiber kugadzira zvisiri-yakarukwa zvinhu.
Munguva iyi, nyika shoma dzakaita seUnited States, Germany neUnited Kingdom ndidzo dzaitsvaga nekugadzira machira asiri akarukwa, uye zvigadzirwa zvawo aive akakora uye akakora semachira asina kuruka.
Chechipiri, nguva yekugadzirwa kwekutengeserana kubva pakupera kwema1950 kusvika pakupera kwema1960.Panguva ino, tekinoroji yakaoma uye tekinoroji yakanyorova inonyanya kushandiswa, uye nhamba huru yemakemikari fibers inoshandiswa kugadzira zvisiri-yakarukwa zvinhu.
3. Nguva yakakosha yekuvandudza, kubva kumavambo ekuma1970 kusvika kuma1980, panguva ino, mitsara yakakwana yekugadzirwa kwepolymerization uye extrusion nzira dzakazvarwa.
Iko kukurumidza kusimukira kweakasiyana akasiyana akakosha mafiber akasarudzika, akadai seakadzika anonyunguduka mafiibhi, anopisa anosunga faibha, bicomponent fibers, ultrafine fibers, nezvimwewo, zvakakurumidza kusimudzira kufambira mberi kweiyo nonwoven material industry.
Munguva iyi, kugadzirwa kwepasi rose kwepasi rose kwakasvika matani 20 000 uye kukosha kwakabuda kwakapfuura mazana maviri emamiriyoni emadhora ekuAmerica.
Iyi indasitiri iri kusimukira yakavakirwa pakubatana kwepetrochemical, makemikari epurasitiki, makemikari akanaka, indasitiri yemapepa uye indasitiri yemachira.Inozivikanwa seindasitiri yekubuda kwezuva muindasitiri yemachira.application.
4.Pahwaro hwekuenderera mberi kwekukura kwekumhanya kwekugadzirwa kwemachira asiri akarukwa, tekinoroji isina kurukwa yakafambira mberi zvakanyanya panguva imwe chete, izvo zvakwezva kutarisisa kwepasirese, uye nzvimbo yekugadzira isina kuruka. jira rakawedzerawo nekukurumidza.
Chechina, nguva yebudiriro yepasi rose, kubva kutanga kwema1990 kusvika parizvino, mabhizinesi asina kurukwa akagadzirwa nekusvetuka-svetuka.
Kuburikidza nehunyanzvi hwekuvandudza tekinoroji yemidziyo, optimization yechimiro chechigadzirwa, midziyo yakangwara, uye chiratidzo chemusika, nezvimwewo, tekinoroji isiri-yakarukwa yave yepamusoro uye yakakura, midziyo yave yakaomarara, kuita kwezvinhu zvisiri-yakarukwa uye zvigadzirwa zvave. yakavandudzwa zvakanyanya, uye huwandu hwekugadzira uye zvigadzirwa zvakatevedzana zvakaramba zvichiwedzerwa.Zvigadzirwa zvitsva, matekinoroji matsva, uye maapplication matsva anobuda chimwe mushure mechimwe.
Munguva iyi, tekinoroji ye-spin-forming uye melt-blown nonwovens yakasimudzirwa nekukurumidza uye kushandiswa mukugadzira, uye vagadziri vemichina vakatangisawo seti yakakwana ye-spin-forming uye yakanyungudika-inoputika-inoputika mitsara yekugadzira isina kuruka kumusika.
Iyo drylaid nonwovens tekinoroji yakaitawo budiriro yakakosha panguva iyi.
