Inayiloni iyi-polymer, okusho ukuthi iyipulasitiki enesakhiwo samangqamuzana senani elikhulu lamayunithi afanayo ahlanganiswe ndawonye.Isifaniso singaba ukuthi kufana nje neketanga lensimbi, elenziwe ngezixhumanisi eziphindaphindayo.Inayiloni iwumndeni wonke wezinhlobo ezifanayo zezinto ezibizwa nge-polyamides.
Esinye sezizathu zokuthi kukhona umndeni wamanylon ukuthi i-DuPont inelungelo lobunikazi befomu lokuqala, ngakho abaqhudelana nabo kwadingeka beze nezinye izindlela.Esinye isizathu ukuthi izinhlobo ezahlukene ze-fiber zinezakhiwo ezihlukene kanye nokusetshenziswa.Isibonelo, i-Kevlar® (impahla ye-bulletproof vest) kanye ne-Nomex® (indwangu engashi yamasudi ezimoto zomjaho namagilavu kahhavini) kuhlobene ngamakhemikhali nenayiloni.
Izinto zendabuko ezifana nokhuni nokotini zikhona emvelweni, kuyilapho inayiloni ingekho.Ipolymer enayiloni yenziwa ngokusabela ndawonye ama-molecule amabili amakhulu ngokuqhathaniswa kusetshenziswa ukushisa okungaba ngu-545°F kanye nokucindezela okuvela kuketela lamandla ezimboni.Lapho amayunithi ehlangana, ayahlangana ukuze akhe i-molecule enkulu nakakhulu.Le polymer eningi iwuhlobo oluvame kakhulu lwenayiloni—olwaziwa ngokuthi inayiloni-6,6, equkethe ama-athomu ekhabhoni ayisithupha.Ngenqubo efanayo, okunye ukuhlukahluka kwenayiloni kwenziwa ngokusabela kumakhemikhali ahlukene okuqala.
Le nqubo idala ishidi noma iribhoni yenayiloni ehlukaniswa ibe ama-chips.Lawa ma-chips manje asewumkhiqizo wazo zonke izinhlobo zemikhiqizo yansuku zonke.Kodwa-ke, izindwangu zenayiloni azenziwa ngama-chips kodwa zenziwe ngemicu yenayiloni, eyimicu yepulasitiki.Le ntambo yenziwa ngokuncibilikisa ama-chip enayiloni bese uwadweba nge-spinneret, okuyisondo elinezimbobo ezincane.Imicu yobude nobukhulu obuhlukene yenziwa ngokusebenzisa izimbobo ezinosayizi abahlukene futhi iwakhiphe ngesivinini esihlukene.Uma imicu eminingi isongwe ndawonye isho ukuqina nokuqina kwentambo.
