Hoʻohana ʻia ka ʻōmaʻomaʻo alkaline i ke kala ʻana i nā fiber acrylic, siliki, hulu hipa, diacetate a me nā pulupulu.ʻOi aku ka maikaʻi o ka hoʻoluʻu ʻana i nā fibers acrylic a me ka diacetate i ka lā a me nā mea wikiwiki ʻē aʻe (kopa, ʻili hou, etc.).ʻOi aku ka maikaʻi o ka wikiwiki o ka hulu hipa i hoʻoluʻu ʻia, ke silika, a me ka pulupulu.Hiki ke kala ʻia i ka ʻili, ka pepa, ka hemp, ka ʻohe, ka lāʻau, a me nā mea ʻē aʻe, a me ka hana ʻana i ka loko kala.Ma hope o ka ʻili fibre acrylic ma hope o ka dyeing alkaline fuxing, hiki ke loaʻa ke kala ʻeleʻele, a hoʻomaikaʻi ka wikiwiki.He kala maʻamau no ka hoʻoholo ʻana i ka waiwai saturation o nā fibers acrylic a me ka coefficient saturation o cationic dyestuff.
