He matera whakamahinga nui ā-mutunga te here rayon, he mea hou rā anō i whakarite i ngā pūnaha whenua me ngā pūnaha hokohoko. Ki te tirohanga i te here whatiwhati cellulose, e whakakotahi ana te here rayon i te waea o ngā pūnaha whenua me te whanonga o ngā pūnaha hanga iho. Ko te here ka hanga i roto i tētahi mātao matihiko, kei reira te kaihokohoko rākau rānei, ki tētahi āheinga cellulose whenua rānei, ka whakariterite haeretia chemically, ka whakawhanake hei herehere māku, mutu noa. E kitea ana ngā āhuatanga nui o ēnei herehere, inaianei ko te mahi pai rawa ki te whakapakari, ko te kuhu pai tonu ki te wai, ko te whakaaturanga rangi pai rawa hoki. I whakaaetia e te rayon i a ia i runga i te hanga whakamahere raima o nehe, e kitea ana i roto i ngā kākahu ahurea, i ngā whakapakanga whare, me ngā whakapakanga hokohoko. Ki te tirohanga i tana rārangi molekula nui, ka whai take te hiahia nui ki te whakapakari, ka whakamana hoki i te whanonga me te kaweke, ka pai noa ki ngā tikanga whakapae me ngā tikanga whakahaere. Ka whakaatu te whakaritenga o tēnei here i tana āhua whakamahinga nui, i te tino pai kē o tēnei kaiwhakarite i te noho tahi me ētahi atu here, ka hanga ai ngā kete me ngā āhuatanga pai ake. Ki te whakamahi mo ngā horopaki hokohoko, ka kitea te pai o te here rayon i roto i te whakapae, kei reira te āhua kikorangi me te āhua māku pai, ka puta ai ngā hua pai rawa. Kei te whakatika tonu te whakaritenga o tēnei matera ki ngā whakahaere taiao rerekē me ngā pora whakapio, ka whai take tonu te whakamahi ake i waenganui i ngā whakapakanga rima.
