Ukuveliswa kwemveliso yee-nonwovens sele kukho malunga nekhulu leminyaka.Imveliso yemizi-mveliso yamalaphu angalukwanga ngendlela yanamhlanje yaqala ukubonakala ngowe-1878, xa inkampani yaseBritani uWilliam Bywater yaphuhlisa ngempumelelo umatshini wokuhlaba inaliti ehlabathini.
Imveliso yokwenyani yanamhlanje yeshishini le-nonwovens yaqala kuphela emva kweMfazwe yesibini yeHlabathi.Ngokuphela kwemfazwe, ihlabathi lingamabhodlo, kwaye imfuno yeempahla ezahlukeneyo ziyanda.
Phantsi kwale meko, ii-nonwovens ziye zakhula ngokukhawuleza kwaye ziye zadlula kwizigaba ezine ukuza kuthi ga ngoku:
1. Ixesha lokukhula lisusela ekuqaleni kweminyaka yee-1940 ukuya kutsho phakathi koo-1950.Uninzi lwamashishini amalaphu asebenzisa izixhobo zokuthintela esele zenziwe ukwenza utshintsho olufanelekileyo kunye nokusebenzisa imicu yendalo ukwenza izinto ezingalukwanga.
Ngeli xesha, ngamazwe ambalwa afana ne-United States, iJamani kunye ne-United Kingdom ayephanda kwaye evelisa amalaphu angalukwanga, kwaye iimveliso zawo ubukhulu becala yayingamalaphu ashinyeneyo nangqindilili afana ne-batt angalukwanga.
Okwesibini, ixesha lemveliso yorhwebo livela ekupheleni kwe-1950 ukuya ekupheleni kwe-1960.Ngeli xesha, itekhnoloji eyomileyo kunye nethekhnoloji emanzi isetyenziswa ikakhulu, kwaye inani elikhulu lemicu yemichiza isetyenziselwa ukwenza izinto ezingalukwanga.
3. Ixesha elibalulekileyo lophuhliso, ukususela ekuqaleni kwe-1970 ukuya ekupheleni kwe-1980, ngeli xesha, isethi epheleleyo yemigca yokuvelisa i-polymerization kunye neendlela ze-extrusion zazalwa.
Uphuhliso olukhawulezayo lweentsinga ezikhethekileyo ezikhethekileyo ezingalukwanga ezikhethekileyo, ezinjengeentsinga ezisezantsi zokunyibilika, iintsinga ze-thermal bonding, ii-bicomponent fibers, i-ultrafine fibers, njl.njl., ikhuthaze ngokukhawuleza inkqubela yoshishino lwemathiriyeli engalukwanga.
Ngeli xesha, imveliso ye-nonwoven yehlabathi ifikelele kwiitoni ezingama-20,000 kwaye ixabiso lemveliso lingaphezulu kwe-200 yezigidi zeedola zaseMelika.
Eli lishishini elikhulayo elisekelwe kwintsebenziswano yepetrochemical, iikhemikhali zeplastiki, iikhemikhali ezilungileyo, ishishini lamaphepha kunye noshishino lwamalaphu.Yaziwa njengeshishini lokuphuma kwelanga kwishishini lelaphu.”isicelo.
4. Ngokwesiseko sokukhula okuqhubekayo ngesantya esiphezulu sokwenziwa kwelaphu elingalukwanga, itekhnoloji yelaphu elingalukwanga yenze inkqubela phambili enkulu ngaxeshanye, ethe yatsala umdla kwihlabathi liphela, kunye nendawo yemveliso engalukwanga. ilaphu liye landa ngokukhawuleza.
Okwesine, ixesha lophuhliso lwehlabathi, ukususela ekuqaleni koo-1990 ukuya kutsho ngoku, amashishini angalukwanga aphuhliswe ngokutsiba nemida.
Ngokusebenzisa izixhobo ezintsha zetekhnoloji, ukwenziwa ngcono kolwakhiwo lwemveliso, izixhobo ezikrelekrele, kunye nophawu lwentengiso, njl.njl., itekhnoloji engalukwanga iye yaphucuka kakhulu kwaye ikhulile, izixhobo ziye zaphucuka ngakumbi, ukusebenza kwezinto ezingalukwanga kunye neemveliso ziye zaphucuka. iphuculwe kakhulu, kwaye umthamo wemveliso kunye nothotho lwemveliso ziye zandiswa ngokuqhubekayo.Iimveliso ezintsha, itekhnoloji entsha, kunye nezicelo ezintsha zivela enye emva kwenye.
Ngeli xesha, itekhnoloji ye-spin-forming kunye ne-melt-blown nonwovens iye yakhuthazwa ngokukhawuleza kwaye yasetyenziswa kwimveliso, kwaye abavelisi boomatshini baye baqalisa iiseti ezipheleleyo ze-spin-forming kunye ne-melt-blown-blown nonwoven production lines to market.
Itekhnoloji ye-drylaid nonwovens nayo yenza inkqubela phambili ebalulekileyo ngeli xesha.
