ʻO nā waiʻawaʻawa kuʻuna e pili ana i nā mea hoʻoheheʻe wai e loaʻa ana nā pūʻulu ʻakika i loko o ke ʻano o ka wai, i hoʻoluʻu pinepine ʻia ma lalo o nā kūlana waikawa.
ʻO ka nānā ʻana o nā wai waika
1. ʻO ka mōʻaukala o nā wai waika
I ka makahiki 1868, ua ʻike ʻia nā wai waihoʻoluʻu ʻakika mua loa, ʻo ia ka triaromatic methane acid dyes, nona ka ikaika.kala ʻanahiki akā ʻilihune ka wikiwiki.
I ka makahiki 1877, ua synthesized i laila ka wai waihoʻoluʻu mua no ke kala hulu hipa, e like me ka ʻulaʻula A. Ua hoʻoholo ʻia ke ʻano kumu.
Ma hope o ka makahiki 1890, ua hana ʻia ka wai waihoʻoluʻu me ka anthraquinone.A ʻoi aku ka nui o ka chromatography piha.
I kēia manawa, aia ma kahi o nā haneli o nā ʻano wai waika, i hoʻohana nui ʻia i ka huluhulu, siliki a me ka nylon, etc.
2. ʻO nā hiʻohiʻona o nā waiʻona
Hoʻokumu ʻia ka pūʻulu ʻakika i nā mea waihoʻoluʻu ʻakika ma ka pūʻulu ʻakika sulfonic (-SO3H) a aia ma ke ʻano o ka paʻakai sodium sulfonic acid (-SO3NA) ma ka mole kala.A ua hoʻokumu ʻia kekahi ma ka sodium carboxylate (-COONa).
Hiki ke hoʻoheheʻe wai ʻia ka wai, ka waihoʻoluʻu ʻālohilohi, ka chromatography piha a me ke ʻano molekala maʻalahi ma mua o nā mea pena ʻē aʻe.No ka nele o ka ʻōnaehana conjugate lōʻihi i loko o nā molekala kala, ua haʻahaʻa ka pololei o nā wai waika.
3. The reaction mechanism of acid dyes
Huluhulu — NH3+ + -O3S — Wailu → Huluhulu — NH3+·-O3S — Waiole
Silika — NH3+ + -O3S — Wailu → Silika — NH3+·-O3S — Waiole
Nilona — NH3+ + -O3S — Wailu → Nylon — NH3+·-O3S — Waiole
Hoʻokaʻawale ʻana i nā wai waiʻakika
1.Classification e ka molecular structure of dye parent
■ Nā waihoʻoluʻu Azo (He 60% ka laulā ākea)
■ Nā mea hoʻoluʻu Anthraquinone (He 20% ka nui o nā moʻo uliuli a me ka ʻōmaʻomaʻo)
■ Nā wai methane triaromatic (He 10% moʻo ʻulaʻula a me ka ʻōmaʻomaʻo)
■ Nā waihoʻoluʻu Heterocyclic (He 10% ka moʻo ʻulaʻula a me ka poni.)
2.Hoʻokaʻawale ʻia e ka pH o nā mea pena
■ Nā waiʻakika i loko o ka ʻauʻau waika ikaika: ʻO ka waiʻona pH he 2.5~4.Maikaʻi ka wikiwiki māmā, akā maikaʻi ʻole ka wikiwiki o ka mālama ʻana i ka pulu.He nani ke kala kala a maikaʻi ka waiwai hoʻohālikelike.
■ Nā waiʻakika i loko o ka ʻauʻau waiuma nāwaliwali: ʻO ka waiʻona pH ʻo 4~5.He haʻahaʻa ka nui o ka pūʻulu ʻakika sulfonic i loko o ke ʻano molekala o ka wai.No laila ʻaʻole liʻiliʻi ka hoʻoheheʻe wai.ʻOi aku ka maikaʻi o ka hoʻokē ʻai ʻana ma mua o nā wai waika i loko o ka ʻauʻau waika ikaika, akāhoʻolikelikeilihune iki ka waiwai.
■ Nā waiʻakika i loko o ka ʻauʻau waiʻawaʻawaʻawaʻawaʻawaʻawa: ʻO ka waiʻona pH he 6-7.ʻOi aku ka haʻahaʻa o ka pūʻulu ʻakika sulfonic i loko o ka molecular structure o ka wai.He haʻahaʻa ka hoʻoheheʻe ʻia o nā wai a maikaʻi ʻole ka waiwai hoʻohālikelike.ʻAʻole lawa ka mālamalama o ka waihoʻoluʻu, akā kiʻekiʻe ka wikiwiki o ka lawelawe ʻana i ka pulu.
ʻO ka wikiwiki kala maʻamau o nā waiʻakika
1.Light fastness
ʻO ia ke kū'ē o ka waihoʻoluʻu o ka textile i ke kukui artificial.ʻO ka maʻamau e hoʻāʻo ʻia e like me ISO105 B02.
2.Ka wikiwiki kalae holoi
ʻO ia ke kūpaʻa o ke kala o ka lole i ka holoi ʻana ma lalo o nā kūlana like ʻole, e like me ISO105 C01\C03\E01, etc.
3.Color fastness i ka hamo
ʻO ia ke kūʻē ʻana o ke kala o ka textile i ka hana ʻānai ʻana.Hiki ke hoʻokaʻawale ʻia ʻo ka wikiwiki i ka hamo maloʻo a me ka wikiwiki i ka hamo pulu.
4.Color fastness i ka wai chlorine
Ua kapa ʻia ʻo ia ka colorfastness i ka wai loko chlorine.ʻO ka mea maʻamau, ʻo ia ke hoʻohālike i ka neʻe ʻana o ka chlorine i loko o kahi wai ʻauʻau e hoʻāʻo ai i ke kūʻē ʻana o ka lole i ka chlorine discoloration.No ka laʻana, ʻo ke ʻano hoʻāʻo ISO105 E03 (ʻO ka maʻi chlorine kūpono ʻo 50ppm.) He kūpono ia no nā lole ʻauʻau nylon.
5.Color fastness i ka hou
ʻO ia ke kūpaʻa o ke kala o ka textile i ka hou kanaka.Wahi a ka waika a me ka alkali o ka hou, hiki ke hoʻokaʻawale ʻia i ka wikiwiki o ka waihoʻoluʻu i ka ʻawaʻawa a me ka wikiwiki o ka waihoʻoluʻu i ka hou alkali.ʻO nā lole i hoʻoluʻu ʻia e nā waiʻawaʻa e hoʻāʻo ʻia no ka wikiwiki o ka waihoʻoluʻu i ka hoʻohu ʻana o ka alkali.
