Ingasetshenziselwa ukuqeda amanzi kanye nobufakazi bamafutha wezindwangu ezihlukahlukene.Ngokushintsha ukwakheka kwe-fiber surface layer, futhi ngokunamathela ngokuqinile ku-fiber noma ngokuhlanganisa ne-chemical fiber, indwangu akulula ukumanziswa ngamanzi, uwoyela kanye namanye amabala, okunikeza indwangu ukumelana okuhle kakhulu kwamanzi namafutha, okungase afinyelele iBanga IV kanye neBanga VI ngokulandelana.I-agent ye-C6 engenawo amanzi kanye ne-oyili exosha i-oyili ayinayo umthelela omubi kwendwangu eqediwe, futhi ayithinti ukungena kwayo kwasekuqaleni nokuzizwa kwayo;Ukuwasha okuhle, indwangu iseyinhle kakhulu emanzini, amafutha kanye nokumelana nokungcola ngemva kokugeza okuphindaphindiwe;Ukuhambisana okuhle, kungasetshenziswa ekugezeni okufanayo nge-softener nezinye izinsiza zokuqeda;Ukuphepha nokuvikelwa kwemvelo, ngaphandle kwe-PFOA ne-PFOS (okuqukethwe kuphansi kunevelu yomkhawulo wokutholwa), ngokuhambisana nezindinganiso zokuthekelisa.
