ʻO nā mea e hoʻohanaʻia nā mika i nā mea i hoʻohanaʻia ma nāʻano hana maʻamau i loko o nāʻano hana e komo pū ai, nā mea kanu a me nā meaʻai. ʻO ke kaʻina hana hana o ka eternase he paʻakikī he paʻakikī paʻakikī, pili i nāʻano he nui, a koi pono i nā loea he nui a me nā mea maʻamau. Ma kēiaʻatikala, e kūkākūkā mākou i nā kiko'ī e hana ai i ke kaʻina hana o nā nalo cellouse.
ʻO ka hana mua i ka hana hana cellouse eter e hana ana ka hoʻomākaukauʻana o nā mea hou o nā lako hana. Ua hoʻohanaʻia nā mea waiwai e hana i nā mea e hiki mai ana i nā mea e hiki mai ana mai ka ulu lāʻau a me ka cotton cotton. Ua kapaʻia ka lāʻau lāʻau a nānāʻia e wehe i kahi lepo nui,ʻoiai ke kaʻina o ka cotton i kahi pulu maikaʻi. A laila ua hōʻemiʻia ka pulp i ka nui e ka hoʻopiliʻana e kiʻi i kahi pauka maikaʻi. ʻO nā lāʻau lāʻau PWDDed a me Wīwī a laila e hoʻopiliʻia ka cotton i nāʻano kiko'ī e pili ana i nā waiwai i makemakeʻia ma nā huahana hope loa.
ʻO ke ala aʻe e pili ana i ke kaʻina hana o keʻano o nā mea hānai i huiʻia. Ua mālama muaʻia ka pulp me kahi maʻi alkaline (maʻamau sodium hydroxide) e wāwahi i ka hana ahi. ʻO ka hopena hopena i laila e mālamaʻia me ka sollent e like me ka mea e like me ka carbon disulfide e hana i ka cellulse xanthate. Ua laweʻia kēia lāʻau lapaʻau i loko o nā pahu me kahi neʻe mau loa o ka pulp. ʻO ka hopena o ka cellouse xanthate e hoʻopauʻia ma o kahi polokalamu extrusion e hana ai i nā filement.
Ma hope mai,ʻo nā file xanthate xanthate xanthate i loko o kahiʻauʻau e loaʻa ana i kaʻauʻau sulfuric sulfuric acid. ʻO kēia mau hopena i ka hoʻoponopono houʻana i nā kaulahao Xanthate Xantase Ua holoiʻia nā mea hou hou i hanaʻia me ka wai e wehe i nā mea i hala ma mua o ka hoʻopiliʻiaʻana. Hoʻohana ke kaʻina hana bleaching e hoʻohana ai i ka pohu hydrogen e keʻokeʻo i nā fibers, e holoiʻia me ka wai a me ka maloʻo.
Ma hope o ka maloʻoʻana o nā fibers cellouse, i lalo o ke kaʻina i kapaʻia he nui. ʻO ke kaʻina hoʻohui e pili ana i ka hoʻomakaʻana o nā hui o Enei, e like me Myyl, Evertl a iʻole nā hui hydryethyl Ke laweʻia nei keʻano o ka hoʻohanaʻana i ka hopena o kahi mea e ae a me ka mea i loko o ka maka o kahi e kū ana i kahi paʻa. Hoʻohana pinepineʻia nā hopena ma lalo o nā kūlana i hoʻopaʻaʻia ma lalo o nā kūlana i hoʻopaʻaʻia i keʻano a me ke kaomi e hōʻoia ai i nā huahana kiʻekiʻe a me ka maʻemaʻe.
I kēia manawa, aia ka Eter Cellulose ma keʻano o ke aniani keʻokeʻo. ʻO ka huahana i hoʻopauʻia e kauʻia i kahi papa hana o ka mana o ka mana kūpono e hōʻoia ai e hālāwai me ka mea makemake a me nā kiko'ī. A laila ua hoʻopauʻia a hoʻounaʻia i ka mea hoʻohana hope.
E hōʻuluʻulu i, e hana i ke kaʻina hana hana o ka celllouse e like me ka hana maʻamau, e hoʻonaninani, e like me ka hoʻomaʻamaʻa maikaʻiʻana. Pono ke kaʻina hana holoʻokoʻa i nā lako hana a me kaʻike i nā hopena o kemika a laweʻia ma lalo o nā kūlana paʻa. Ka hanaʻana i nā leka uila he hopena paʻakikī a me ka hoʻopauʻana i ka manawa, akā he mea nui ma nāʻoihana he nui.
