Indwangu engalukiweyakhiwe ngemicu eqondisayo noma engahleliwe.Isizukulwane esisha sezinto zokuvikela imvelo, ezivikela umswakama, eziphefumulayo, ezivumelana nezimo, ezilula, ezingashi, ukubola kalula, ezingenabuthi futhi ezingacasuli, ezinombala ocebile, intengo ephansi, ezigaywa kabusha, njll. Ukuze isibonelo, ama-polypropylene (pp material) ama-granules asetshenziswa kakhulu njengezinto ezingavuthiwe, ezikhiqizwa inqubo yesinyathelo esisodwa esiqhubekayo sokuncibilika kwezinga lokushisa eliphezulu, ukuphotha, ukubeka, ukucindezela okushisayo nokubopha.Ibizwa ngendwangu ngenxa yokubukeka kwayo nezinye izakhiwo.
Njengamanje, imicu eyenziwe ngumuntu isabusa ukukhiqizwa kwezindwangu ezingalukiwe, futhi lesi simo ngeke sishintshe kakhulu kuze kube ngu-2007. I-63% yemicu esetshenziswaindwangu engalukiweukukhiqizwa emhlabeni wonke polypropylene, 23% polyester, 8% viscose, 2% fibre acrylic, 1.5% polyamide, futhi 3% asele eminye imicu.
Eminyakeni yamuva, ukusetshenziswa kweizindwangu ezingalukiweezintweni zokumuncwa ezihlanzekile, izinto zokwelapha, izimoto zokuhamba, nezinto zendwangu yezicathulo kuye kwanda kakhulu.
Ukuthuthukiswa kwezentengiselwano kwemicu eyenziwe umuntu kanye nokusetshenziswa kochwepheshe kwezindwangu ezingalukiwe: Ngenxa yokusungulwa kwezivumelwano zomnotho zamazwe ngamazwe, ukuhweba kwama-microfibers, imicu eyinhlanganisela, imicu ebolayo kanye nezinhlobo ezintsha zemicu ye-polyester sekukhulile.Lokhu kunomthelela omkhulu ezindwangu ezingezona ezilukiwe, kodwa kunomthelela omncane ezembathweni nasezindwangu ezilukiwe.Ukushintshwa kwezindwangu nezinye izinto ezisetshenziswayo: Lokhu kuhlanganisa izindwangu ezingalukiwe, izindwangu zokuluka, amafilimu epulasitiki, igwebu le-polyurea, ukhuni olukhuni, isikhumba, njll. Lokhu kunqunywa izindleko nokusebenza kwezidingo zomkhiqizo.Ukwethulwa kwezinqubo zokukhiqiza ezintsha, ezonga kakhulu futhi eziphumelelayo: okungukuthi, ukusetshenziswa kwezindwangu ezintsha ezincintisanayo ezingalukiwe ezenziwe ngama-polymers, kanye nokwethulwa kwemicu ekhethekile nezithasiselo zendwangu ezingalukiwe.
Imicu emithathu emikhulu esetshenziswa ekukhiqizweni kwendwangu engalukiwe i-polypropylene fiber (62% yenani lonke), i-polyester fiber (24% yenani eliphelele) kanye ne-viscose fiber (8% yesamba).Kusukela ngo-1970 kuya ku-1985, i-viscose fiber yayisetshenziswa kakhulu ekukhiqizweni okungeyona i-nonwoven.Kodwa-ke, kule minyaka engu-5 yakamuva, ukusetshenziswa kwe-polypropylene fiber kanye ne-polyester fiber sekuqalile ukubusa emkhakheni wezinto ezihlanzekile zokumuncwa kanye nezindwangu zezokwelapha.Emakethe yokuqala yokukhiqiza indwangu engalukiwe, ukusetshenziswa kwenayiloni kukhulu kakhulu.Kusukela ngo-1998, ukusetshenziswa kwe-acrylic fiber kuye kwanda, ikakhulukazi emkhakheni wokukhiqiza isikhumba sokwenziwa.
