Njengesembozo esiguquguqukayo esinemisebenzi ewumongo yendawo yokukhosela nokuvikela, umlando woseyili ungalandelelwa emuva ezenzweni zakuqala zabantu ekuphenduleni izinselele zemvelo. Kusukela ekuqaleni kwesigaba sempucuko yasendulo, abantu bazama ukusebenzisa imicu yemvelo nezindlela ezilula zokucubungula ukuze bakhe imvula nomoya ovikelayo, benze isibonelo sikaseyili. Ngokuthuthuka kokutholwa kwezinto ezibonakalayo nezindlela zokucubungula, oseyili bashintsha kancane kancane besuka ezintweni eziphuthumayo zesikhashana bangena ezindleleni ezizinzile neziguquguqukayo zokukhiqiza kanye nentuthuko eqhubekayo yesikhathi sokuphila sansuku zonke.
Ngesikhathi sempucuko yezolimo, indwangu eqinile elukwe ngemicu yezitshalo efana ne-hemp, ukotini nefilakisi yayisetshenziswa kabanzi emhlabeni wonke. Wawungangenwa amanzi ngamafutha, izinhlaka, noma isikhumba sezilwane futhi wawusetshenziswa njengesembozo sezinqolobane, ukuthutha izimpahla, nendawo yokukhosela yesikhashana yamakamu amasosha. Izicelo ezifanayo zirekhodwa emibhalweni nezinsalela zaseGibhithe lasendulo, isiGreki sasendulo, nesiShayina sasendulo. Nakuba lawa maseyili okuqala ayengajwayelekile, asevele ahlanganisa umqondo owumongo wokusebenzisa indwangu ehlanganiswe nezinto ezisetshenziswa yi-hydrophobic ukumelana namanzi emvula, abeka isisekelo sokuziphendukela kwemvelo kwakamuva kwezobuchwepheshe.
INguquko Yezimboni yaletha ukukhuphuka okukhulu ekuthuthukisweni koseyili, ngokukhuphuka kwemishini yendwangu kanye nemboni yamakhemikhali. Kusukela ngekhulu le-19 kuya phambili, ukwamukelwa okusabalele komshini{2}}wokuluka ubuchwepheshe kwandise kakhulu ububanzi nokuminyana kwezindwangu eziyisisekelo, okuholela ekuthuthukisweni okuphawulekayo ekusebenzeni kahle kokukhiqiza. Ngaso leso sikhathi, kwavela okuphuma kwetiyela yamalahle, irabha, nezinsalela zokwenziwa zakuqala, okuhlinzeka izindwangu ezihlala isikhathi eside nezifanayo ezingangeni manzi kanye{4}}nezimbotshana zokubola. Ekuqaleni kwekhulu lama-20, izinto ezifana ne-polyvinyl chloride (PVC) zaqala ukusetshenziswa ezinkundleni zempi nezokuthutha, futhi ukumelana kwazo nesimo sezulu esihle namandla emishini kwasheshe kwaqashelwa, kuqhuba oseyili kusukela ekukhiqizweni okwenziwe ngezandla kuya{7}}ezisezingeni eliphezulu ekukhiqizeni izimboni.
Maphakathi-kuya{1}}sekupheleni kwekhulunyaka lama-20, ngokuvuthwa kwemboni ye-petrochemical kanye nokuthuthuka kwesayensi yezinto ze-polymer, izinhlobonhlobo zamaseyili ziye zahlukahluka kakhulu. Inhlanganisela yezindwangu zesisekelo se-polyester fibre ezinezingubo ezihambisana nemvelo ezifana ne-polyurethane (PU) ne-acrylic yavumela imikhiqizo ukuthi igcine amandla aphezulu ngenkathi inciphisa isisindo futhi ithuthukisa ukuguquguquka. Ngalesi sikhathi, ububanzi bokusetshenziswa koseyili banwetshwa kusukela kwezokuthutha ezivamile, indawo yokugcina impahla, nokuvikelwa kwezolimo ukuya ekuzijabulisa kwangaphandle, imicimbi yezemidlalo, ukwakhiwa kwesikhashana, kanye nokusabela ezimeni eziphuthumayo. Imisebenzi yabo iphinde yanwetshwa ukusuka endaweni yokukhosela ukuze ihlanganise izakhiwo eziyinhlanganisela ezifana nokuvikela umoya, ukugoba amalangabi, ukumelana ne-UV, kanye nokufakwa kwe-thermal.
Kuwo wonke umlando wawo, ukuvela kwamaseyili kuye kwaxhunyaniswa eduze nokuhlola kwesintu izakhiwo zezinto ezibonakalayo kanye nemizamo yaso yokuthuthukisa ukuguquguquka kwayo emvelweni. Kusukela ekuhlanganiseni okulula kwemicu yemvelo namafutha kuya ekukhiqizweni okunembayo kwezakhiwo zesimanje eziyinhlanganisela ye-polymer, oseyili ababonanga nje inqubekelaphambili yobuchwepheshe bezimboni kodwa baphinde babonisa izinguquko zezenhlalo-ezimweni zomnotho nezindlela zokuphila kuzo zonke izinkathi ezihlukene, baba umthwali wezinto ezibalulekile ukuze isintu sibhekane nemvelo futhi sandise indawo yayo.
