ʻO nā mea waiʻona

  • Solvent dyes

    Nā wai hoʻoheheʻe

    ʻO ka wai hoʻoheheʻe he mea hoʻoheheʻe i hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik a hoʻohana pinepine ʻia ma ke ʻano he hopena i loko o ia mau mea hoʻoheheʻe.Hoʻohana ʻia kēia ʻāpana kala e kala i nā mea e like me ka waxes, lubricants, plastics, a me nā mea nonpolar-based hydrocarbon.ʻO kēlā me kēia mea pena i hoʻohana ʻia i ka wahie, no ka laʻana, e noʻonoʻo ʻia he mea hoʻoheheʻe a ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai.

  • Disperse dyes

    E hoʻopuehu i nā kala

    ʻO ka disperse dye kekahi ʻano mea lāʻau ʻaʻole i hui pū ʻia.ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai a hoʻohana ʻia no ke kala ʻana i nā mea textile synthetic.Loaʻa ka hopena maikaʻi loa i ka wā e make ai ke kaʻina hana i nā wela kiʻekiʻe.Ma ke ʻano kikoʻī, hiki i nā hāʻina ma kahi o 120°C a 130°C ke hiki i nā mea hoʻoheheʻe ke hana i ko lākou pae maikaʻi loa.

    Hāʻawi ʻo Hermeta i nā mea ʻulaʻula me nā ʻano hana like ʻole no ke kala ʻana i nā synthetics e like me ka polyester, nylon, cellulose acetate, vilene, synthetic velvets a me PVC.ʻAʻole ikaika loa ko lākou hopena ma ka polyester, ma muli o ke ʻano molekala, e ʻae wale ana i ka pastel a hiki i nā aniani waena, akā hiki ke hoʻokō ʻia ke kala piha i ka wā e paʻi ai ka wela me nā mea hoʻopuehu.Hoʻohana pū ʻia nā mea ʻulaʻula no ka paʻi sublimation o nā fibers synthetic a he mau kala i hoʻohana ʻia i ka hana ʻana i nā peni penikala "hao-on" hoʻololi.Hiki ke hoʻohana ʻia i loko o nā resins a me nā plastics no ka hoʻohana ʻana i ka ʻili a me ka hoʻohana kala maʻamau.

  • Metal Complex Dyes

    Nā Waikani Metala Paʻakikī

    ʻO ka wai waihoʻoluʻu paʻakikī metala he ʻohana o nā mea pena i loaʻa nā metala i hui pū ʻia me ka ʻāpana organik.He nui nā mea hoʻonaʻokoʻa azo, ʻoi aku ka nui o nā mea i loaʻa mai nā naphthols, e hana i nā paʻakikī metala ma o ka paʻakikī o kekahi o nā kikowaena azo nitrogen.ʻO nā kala paʻakikī metala he mau mea hoʻonanea i hoʻopaʻa ʻia e hōʻike ana i ka pili nui i nā fiber protein.I loko o kēia mea pena, ua hui pū ʻia hoʻokahi a i ʻole ʻelua mau molekule wai me ka ion metala.ʻO ka mole kala ka mea maʻamau he ʻano monoazo i loaʻa nā pūʻulu hou e like me ka hydroxyl, carboxyl a i ʻole amino, i hiki ke hana i kahi paʻakikī hoʻohui pū me nā ion metala hoʻololi e like me ka chromium, cobalt, nickel a me ke keleawe.
