Indwangu ye-polyester viscose iyimpahla yendwangu esebenzayo ehlanganiswe noma ehlanganiswe ne-polyester (i-polyester fiber) kanye ne-viscose ({0}}ifayibha ye-cellulose eyenziwe ngumuntu). Isetshenziswa kabanzi kwezembatho, izindwangu zasekhaya, nezindwangu zezimboni. Inani layo eliyinhloko lisekuhlanganiseni izici ezihambisanayo zemicu emibili, igcine amandla nokuqina kwe-polyester ngokunethezeka nokumuncwa komswakama we-viscose, okwenza inhlanganisela eyingqayizivele yezinzuzo zokusebenza.
Ngokusekelwe ezicini zempahla yokusetshenziswa, i-polyester ivamise ukubiza u-60%-80%, okwenza indwangu ibe mnandi, ingezwani{5}}izwe ukumelana, ukuwashwa kalula nokomiswa ngokushesha, nokuzinza kobukhulu. Indawo yayo yokuncibilika ephezulu (cishe ama-degree angu-255) iyenza imelane-nezinga lokushisa eliphezulu loku-ayina, okuyenza ifanelekele ukuwashwa njalo noma{10}}ukusetshenziswa isikhathi eside. U-20%-40% wokuqukethwe kwefayibha ye-viscose kuthuthukisa kakhulu isikhumba sendwangu{16}ukuzizwa kunobungane nokumunca umswakama kanye nokuphefumula. Ukubuyiswa komswakama we-Viscose kungafinyelela ku-13%, okwedlula kude i-polyester's 0.4%, kuthuthukisa ngempumelelo ukugxusha okuhambisana nezindwangu ezihlanzekile ze-polyester. Lo mklamo wesakhiwo uvumela izindwangu ze-polyester-viscose ukuthi zigcine izakhiwo zazo zokunakekelwa kalula ngenkathi zifana kakhulu nesipiliyoni sokugqoka semicu yemvelo.
Mayelana nokukhiqiza, lezi zindwangu zivame ukusebenzisa amasu okuphotha iringi noma{0}}avulekile{0}}amasu okuphotha ekugcineni ukuze kuthuthukiswe ukuhlelwa kwefayibha. Ukulungisa isilinganiso senhlanganisela kuvumela ukulawula okunembile kwezici zokusebenza: izinguqulo ezinokuqukethwe okuphezulu kwe-polyester zifanele ukugqokwa-izinhlelo zokusebenza ezingazweli njengezingubo zokusebenza nezangaphandle, kuyilapho izinguqulo ezinokuqukethwe okuphezulu kwe-viscose zivame ukusetshenziswa kumahembe nasekugqokeni okungavamile, lapho ukunethezeka kubaluleke kakhulu. Mayelana nokudaya, i-polyester idinga odayi abasabalalisa emazingeni okushisa aphezulu kanye nokucindezela okuphezulu, kuyilapho i-viscose ifanele igumbi-lokudayila izinga lokushisa elinodayi abasebenzayo. Ngakho-ke, izindlela zokudaya ezihlukanisiwe noma{6}}zokugeza zokugeza ziyadingeka ukuze kuqinisekiswe ukushesha kombala okungaguquki.
Amathrendi amanje embonini abonisa ukuthi i-polyester-indwangu ye-viscose ithuthukela ekusebenzeni kahle: ukungeza ama-antimicrobial kanye ne-UV{1}}engazweli ukuze kwandiswe inani elingeziwe, noma ukuxutshwa ne-spandex ukuze kuthuthukiswe ukunwebeka ukuze kuhlangatshezwane nezidingo zemakethe yezingubo zemidlalo. Ngokukhula kwezidingo zokuvikelwa kwemvelo, inhlanganisela ye-polyester egaywe kabusha kanye ne-lyocell ({3}}okungenye yesizukulwane esilandelayo se-viscose) nayo iyakhula, iqhubekisela lesi sigaba kwezindwangu ezisimeme. Izici zayo "zokusebenza okunokulinganisela nezindleko ezilawulekayo" ziyenza ikwazi ukuqhubeka nokuba nesikhundla esibalulekile phakathi-nobubanzi bemakethe yezindwangu.
