Kei te whakaatuhia te hoahoa hanganga o te kiriata turanga PET noa i te pikitia. Ko te kohu teitei PM12 me te iti
He rauemi whānuitia ngā kiriata polyester noa o te haze SFF51 i roto i te umanga tākai me te tā. He tino mārama te āhua o te kiriata, he iti hoki te haze, ā, ka taea te whakaatu pai i te āhua o te hua me te whakapai ake i te kounga o te tākai. I roto i tēnei whakataki tirotiro hua, ka ako atu tātou mō ngā āhuatanga o ēnei kiriata.
Ko ngā kiriata polyester noa e hangai ana ki te kohu teitei PM12 me te kohu iti SFF51 he mea hanga mai i ngā rauemi polyester kounga teitei, he tino pai ngā āhuatanga ā-tinana me te pumau matū. Nā ōna āhuatanga kohu teitei PM12 ka taea te whakaiti i te whakaputanga hiko pateko i te wā o te tukanga tākai me te whakapai ake i te whai huatanga o te tākai. Ka taea e te SFF51 kohu iti te whakaiti i te āhuatanga pōuriuri i runga i te mata o te kiriata, kia mārama ake ai, kia mārama ake ai te āhua o te hua.
I te wā e tirotirohia ana te hua, me aro nui ki te matotoru, te mārama, te kaha kume, te ātete wera me ētahi atu tohu o te kiriata. He pai te mahi a ngā kiriata polyester noa o te PM12 kohu teitei me te SFF51 kohu iti i roto i ēnei āhuatanga, ā, ka taea te whakatutuki i ngā hiahia rerekē mō te takai me te tā.
