ʻO nā mea hana ʻili biobased USDA i hōʻoia ʻia i ka ʻili maiʻa vegan maikaʻi maikaʻi ʻia ʻo ka ʻili ʻohe ʻohe fiber bio-based ʻili maiʻa ʻili huaʻai.

ʻO ka ʻili PU kahi ʻano ʻili synthetic, nona ka inoa piha he polyurethane synthetic leather. He ʻili hana ia i hana ʻia mai ka resin polyurethane a me nā mea hoʻohui ʻē aʻe ma o ke ʻano o nā hopena kemika. ʻO kaʻili PU kahi kokoke loa i kaʻili maoli i ka nānāʻana, ka manaʻo a me ka hana, no laila ua hoʻohana nuiʻia i nā lole, nā kāmaʻa, nā lako, nāʻeke a me nā māla'ē aʻe.

ʻO ka mea mua, ʻo ka mea maka o ka ʻili PU ka nui o ka polyurethane resin, ʻo ia ka polymer compound me ka elasticity maikaʻi a me ke kūpaʻa ʻana, a hiki ke hoʻohālikelike i ke ʻano o ka ʻili maoli. Ke hoʻohālikelike ʻia me ka ʻili maoli, ʻoi aku ka maikaʻi o ke kaʻina hana o ka ʻili PU, ʻaʻole pono ka nui o ka hulu holoholona, ​​​​e hōʻemi i ka pōʻino i nā holoholona, ​​​​a pili pū me ka manaʻo o ka hoʻomohala hoʻomau i ka nohona hou.

ʻO ka lua, he nui nā waiwai maikaʻi o ka ʻili PU. ʻO ka mea mua, ʻo ka pale ʻana i ka lole. Ua mālama kūikawā ʻia ka ʻili PU e hoʻomaʻemaʻe i ka ʻili, ʻoi aku ka maikaʻi o ka lole a me ka waimaka, a ʻoi aku ka lōʻihi. ʻO ka lua o ka hana wai. Hoʻomaʻamaʻa pinepine ʻia ka ʻili o ka ʻili PU me ka wai ʻole, kahi mea paʻakikī i ka wai ke komo a maʻalahi hoʻi e hoʻomaʻemaʻe. He mea kūpono ia no nā lako, nā noho kaʻa a me nā mea ʻē aʻe. Eia kekahi, loaʻa i ka ʻili PU nā hiʻohiʻona o ka palupalu maikaʻi, ke ʻano māmā, a me ka hana maʻalahi, hiki ke hoʻokō i nā pono o nā hoʻohana like ʻole.
Eia kekahi, maikaʻi loa ke ʻano o ka ʻili PU. No ka mea he mea hana kanaka ka ʻili PU, hiki ke pena ʻia, paʻi ʻia a me nā hana ʻē aʻe e like me ka makemake o nā mea hoʻolālā. Loaʻa iā ia nā kala momona a me nā ʻano like ʻole, hiki ke hoʻokō i nā pono aesthetic o nā mea kūʻai like ʻole. I ka manawa like, hiki i ka ʻili o ka ʻili PU ke hoʻohālikelike i ka ʻili maoli, e ʻoi aku ka ʻoiaʻiʻo a paʻakikī ke hoʻokaʻawale i ka ʻoiaʻiʻo mai ka hoʻopunipuni.

Ma keʻano holoʻokoʻa, ʻo ka ʻili PU kahi mea ʻili synthetic maikaʻi loa me ka hana kūlohelohe maikaʻi, ke kūpaʻa ʻana, ka hana wai a me ka hiʻohiʻona maikaʻi loa.
