Holoi enzyme

Ma ke kaʻina hana holoi enzyme, hana nā cellulases i ka cellulose i ʻike ʻia ma luna o ka pulupulu pulupulu, e hoʻokuʻu ana i ka wai indigo mai ka lole. Hiki ke hoʻololi ʻia ka hopena i loaʻa ma ka holoi ʻana i ka enzyme ma o ka hoʻohana ʻana i ka cellulase o ka pH neutral a i ʻole acidic a me ka hoʻokomo ʻana i ka hoʻonāukiuki mechanical hou e like me nā pōpō kila.

Hoʻohālikelike i nā ʻenehana ʻē aʻe, ʻoi aku ka maikaʻi o ka holoi ʻana i ka Enzyme ma mua o ka holoi ʻana i ka pōhaku a i ʻole ka holoi wai wai no ka mea ʻoi aku ka maikaʻi o ka wai. ʻO nā ʻāpana pumice koena mai ka holoi ʻana i nā pōhaku e koi ana i ka nui o ka wai e hoʻopau ʻia, a ʻo ka holoi ʻana i ka waika e pili ana i nā pōʻai holoi he nui e hana i ka hopena i makemake ʻia.[5] ʻO ka substrate-specificity o nā enzymes e hoʻomaʻemaʻe i ka ʻenehana ma mua o nā ʻano hana ʻē aʻe o ka hana denim.

Loaʻa iā ia nā pōʻino, ma ka holoi ʻana i ka enzyme, ʻo ka wai i hoʻokuʻu ʻia e ka hana enzymatic e waiho hou i ka textile ("back staining"). Ua hoʻohewa nā loea holoi holoi ʻo Arianna Bolzoni lāua ʻo Troy Strebe i ka maikaʻi o ka denim holoi ʻana i ka enzyme i hoʻohālikelike ʻia me ka denim holoi pōhaku akā ʻae lākou ʻaʻole e ʻike ʻia ka ʻokoʻa e ka mea kūʻai maʻamau.

A e pili ana i ka Moʻolelo, I ka waena o 1980s, ka ʻike ʻana i ka hopena o ke kaiapuni o ka holoi ʻana i ka pōhaku a me ka hoʻonui ʻana i nā lula kaiapuni i koi ai i kahi koho hoʻomau. Ua hoʻokomo ʻia ka holoi ʻana i ka enzyme ma ʻEulopa i ka makahiki 1989 a ua lawe ʻia ma ʻAmelika Hui Pū ʻIa i ka makahiki aʻe. Ua lilo ka ʻenehana i kumuhana o ka noiʻi ʻepekema ikaika loa mai ka hopena o 1990s. I ka makahiki 2017, ua hoʻomohala ʻo Novozymes i kahi ʻenehana e pīpī pololei i nā enzyme ma luna o ka denim i loko o kahi ʻōnaehana mīkini holoi pani e kūʻē i ka hoʻohui ʻana i nā enzymes i kahi mīkini holoi hāmama, e hoʻemi hou i ka wai e pono ai no ka holoi enzyme.
