ʻO ka ʻokoʻa nui ma waena o nā pigments a me nā dyes ʻo kā lākou noi. Hoʻohana nui ʻia nā dyes no nā lole, ʻoiai ʻo nā pigments ʻaʻole nā leka.
ʻO ke kumu he ʻokoʻa nā pigments a me nā dyes no ka mea he pilina ko nā dyes, hiki ke ʻike ʻia hoʻi he pololei, no ka mea hiki ke hoʻopili ʻia a hoʻopaʻa ʻia nā lole a me nā dyes e nā molekala fiber; ʻAʻohe pilina o nā pigments no nā mea kala āpau, hilinaʻi nui i nā resins, nā mea hoʻopili, a me nā mea ʻē aʻe e hoʻoluʻu i nā huahana. Hoʻoikaika nā dyes i ka transparency a he ʻōlinolino maikaʻi ko lākou; Hoʻoikaika nā pigments i nā waiwai uhi a he kūpaʻa maikaʻi ko lākou.
ʻEkolu ʻokoʻa ma waena o nā pigments a me nā dyes:
ʻO ka ʻokoʻa mua ma waena o nā pigments a me nā dyes, ʻo ia ka Solubility like ʻole. ʻO ka ʻokoʻa nui ma waena o nā pigments a me nā dyes, ʻo ia ko lākou solubility. E like me ka mea i ʻike nui ʻia, ʻaʻole hiki ke hoʻoheheʻe ʻia nā pigments i nā wai, ʻoiai hiki ke hoʻoheheʻe pololei ʻia nā dyes i nā wai e like me ka wai, ka waikawa, a pēlā aku.
ʻO ka lua o ka ʻokoʻa ma waena o nā pigments a me nā dyes aia i kā lākou mau ʻano kala like ʻole. ʻO ka pigment kahi mea pauka kala e pono e ninini ʻia i loko o ka wai ma mua o ka kala ʻana. ʻOiai ʻaʻole ia e pala a hoʻoheheʻe ʻia i loko o ka wai, e hoʻopuehu like ʻia. Ma hope o ka hoʻowali like ʻana, hiki i nā mea hoʻohana ke hoʻomaka i ke kala ʻana me kahi palaki. ʻO ke ʻano kala o nā dyes, ʻo ia ke ninini iā lākou i loko o kahi wai, e kali a hiki i ka hoʻoheheʻe loa ʻia ʻana i loko o ka wai, a laila e kau i ka palaki i loko o ka wai no ka hoʻoluʻu ʻana, a laila e lawe i waho i ka palaki e palaki pololei a hoʻopili i ke kala.
ʻO ka ʻokoʻa hope loa ma waena o nā pigments a me nā dyes he mau hoʻohana like ʻole. Ma hope o ka heluhelu ʻana i nā ʻokoʻa ʻelua i luna, e nānā kākou i ka ʻokoʻa hope loa, ʻo ia ka noi. Hoʻohana nui ʻia nā pigments i nā uhi, nā ʻīnika, ka paʻi ʻana a me ka hoʻoluʻu ʻana, a pēlā aku; ʻO nā dyes, ma ka ʻaoʻao ʻē aʻe, hoʻohana pinepine ʻia i nā mea fiber, ka ʻenekinia kemika, a i ʻole ka hoʻonaninani hale.
Hiki i nā mea kūʻai ke koho i nā pigments a i ʻole nā dyes i ke kūʻai ʻana.
