Ukususela malunga nenkulungwane eyadlulayo, ii-nonwovens ziye zaveliswa kwimizi-mveliso. Ngomatshini wokuqala wehlabathi wokuhlaba inaliti ophumeleleyo owaphuhliswa ngo-1878 yinkampani yaseBritani uWilliam Bywater, ukuveliswa kwelaphu elingalukwanga ngokwendlela yale mihla kwaqhuba.
Kuphela kusemva kweMfazwe Yehlabathi II apho ishishini lelaphu elingalukwanga laqalisa ukuvelisa ngokwenene ngendlela yale mihla. Ihlabathi alinantsingiselo ngoku ukuba imfazwe iphelile, kwaye kukho imarike ekhulayo yeentlobo ezahlukeneyo zeempahla.
Ngenxa yoku, ilaphu elingalukwanga likhule ngokukhawuleza kwaye lidlule kwizigaba ezine ukuza kuthi ga ngoku:
1. Ukususela ekuqaleni kweminyaka yee-1940 ukuya phakathi koo-1950 lixesha lokukhula.
Uninzi lwabavelisi belaphu abangalukwanga basebenzisa izixhobo zendalo kunye nezixhobo zokuthintela esele zenziwe ukwenza uhlengahlengiso oluyimfuneko.
Ngamazwe ambalwa kuphela, kuquka iUnited States, iJamani, neUnited Kingdom, ebesenza uphando kunye nokwenza amalaphu angalukwanga ngeli xesha. Uninzi lweminikelo yabo yayingamalaphu ashinyeneyo angalukwanga afana namalulwane.
2. I-1960 kunye nokuphela kwe-1950 yiminyaka yemveliso yorhwebo. Izinto ezingalukwanga ngoku zenziwe kusetyenziswa imicu emininzi yeekhemikhali kwaye ngokuyintloko iindidi ezimbini zobuchwepheshe: zimanzi kwaye zomile.
3. Ngexesha lesigaba esibalulekileyo sophuhliso esisusela ebutsheni boo-1970 ukuya ekupheleni koo-1980, uluhlu olubanzi lwemigca yemveliso yepolymerization kunye nobuchule bokukhulisa bavele. Uphuhliso olukhawulezayo lwamalaphu amaninzi awodwa angalukwanga, aquka i-microfiber, ifayibha ephantsi enyibilikayo, ifayibha yokudibanisa i-thermal, kunye nefayibha ye-bicomponent, ikhuthaze ngokukhawuleza inkqubela yeshishini lezinto ezingalukwanga.
Eli licandelo elisaqalayo elisekwe kwintsebenziswano yepetrochemical, iplastiki, ifayini, iphepha, kunye namashishini amalaphu. Kushishino lwamalaphu, kubhekiselwa kulo “njengeshishini lokuphuma kwelanga.”
4. Amashishini angalukwanga aye anda kakhulu ngexesha lophuhliso lwehlabathi, elaqala ekuqaleni kweminyaka yee-1990 kwaye lisaqhubeka nanamhlanje.
Itekhnoloji yelaphu engalukiweyo ikhule ngakumbi kwaye iqolile, izixhobo ziye zaphucuka ngakumbi, ukusebenza kwezixhobo ezingalukiyo kunye neemveliso ziphuculwe kakhulu, kwaye umthamo wemveliso kunye nothotho lwemveliso ziye zanda ngokuqhubekayo ngokusungulwa kweteknoloji yezixhobo, ukulungiswa kobume bemveliso, izixhobo ezikrelekrele, uphawu lwentengiso, njl njl
Ukongeza kubavelisi boomatshini abazisa iiseti ezipheleleyo zokwenziwa kwelaphu elijikelezayo kunye nemigca yokuvelisa ilaphu elingalukwanga elinyibilikayo kwintengiso, eli xesha libone inkqubela ekhawulezileyo kunye nokusetyenziswa kobu buchwepheshe ekwenzeni ilaphu elingalukwanga.
Ngeli xesha, bekukho nenkqubela phambili ebalulekileyo kwitekhnoloji yee-nonwovens ezomileyo. Ilaphu le-spunlace elingalukwanga laziswa emarikeni, kwaye itekhnoloji enje ngebhondi eshushu eqengqelekayo kunye ne-foam impregnation bonding yamkelwa kwaye yenziwa yafana.
