Nui nā ʻano o nā mea pena, ʻōlelo mua ka mea hoʻolako wai hoʻoula hou e pili ana i nā pelo reactive, he mea maʻamau a hoʻohana maʻamau ka pelo reactive.
Wehewehe ʻana o nā mea hoʻonaninani
ʻO ka waihoʻoluʻu hou: ʻO ka wai hoʻoula hou, ʻike ʻia hoʻi ʻo reactive dye, kahi ʻano o ka wai e hoʻopili me nā fiber i ka wā o ke kala ʻana.Aia i loko o kēia ʻano mole kala ka hui i hiki ke hana kemika me ka fiber.I ka wā o ka hoʻoluʻu ʻana, hoʻopili ke kala me ka fiber, e hana ana i kahi paʻa covalent ma waena o nā mea ʻelua a lilo i mea holoʻokoʻa, kahi e hoʻomaikaʻi ai i ka wikiwiki i ka holoi ʻana a me ka hamo.
Hoʻokumu ʻia nā mea pena hoʻoula me nā mea pena makua, nā hui hoʻohui a me nā pūʻulu reactive.He azo, anthraquinone, phthalocyanine structure, etc. ʻO nā hui reactive maʻamau ka chlorinated junsanzhen (X-type a me K-type), vinyl sulfone sulfate (KN-type) a me ka hui pālua-reactive (M-type).Loaʻa i nā molekala kala ʻulaʻula nā hui kemika, hiki ke hana me ka pulupulu, ka hulu hipa a me nā mea ʻē aʻe i loko o ka hoʻonā wai e hana i kahi paʻa maʻamau, no laila ʻoi aku ka wikiwiki o ka holoi ʻana i ka lole i hoʻopau ʻia.
Hiki ke hoʻoheheʻe ʻia i ka wai a hiki ke hoʻopaʻa paʻa me nā fiber cellulose.Loaʻa iā ia ka waihoʻoluʻu ʻālohilohi, maikaʻi ka hoʻokō pae ʻana, hiki ke uhi i kekahi mau hemahema textile, a loaʻa ka wikiwiki kopa.Eia nō naʻe, ʻaʻole kūʻē ka hapa nui o nā mea pena i ka chlorine bleaching a paʻakikī i nā waikawa a me nā alkali.E noʻonoʻo i ka wikiwiki o ka wā ke hoʻoluli i nā kala māmā.Hiki i nā mea hoʻonanea ke kala i ka pulupulu, viscose, siliki, hulu hipa, nylon a me nā mea ʻē aʻe.

Ka hoʻokaʻawale ʻana o nā mea hoʻonaninani
Wahi a nā pūʻulu hana like ʻole, hiki ke hoʻokaʻawale ʻia nā mea hoʻonaninani i ʻelua mau ʻāpana: symmetric triazene type a me vinyl sulfone type.
ʻAno triazene symmetric: Ma kēia ʻano o ka wai hoʻoula hou, ʻoi aku ka ikaika o ke ʻano kemika o ka atom chlorine reactive.I ka wā kala, ua pani ʻia nā ʻātoma chlorine e nā fiber cellulose i loko o kahi ʻano alkaline a lilo i hui haʻalele.ʻO ka pane ʻana ma waena o ka waiʻona a me ka fiber cellulose, he bimolecular nucleophilic substitution reaction.
ʻAno Vinyl sulfone: ʻO ka pūʻulu reactive i loko o kēia ʻano mea hoʻoheheʻe reactive he vinyl sulfone (D-SO2CH = CH2) a i ʻole β-hydroxyethyl sulfone sulfate.I ka wā kala, hoʻopau ʻia ka β-hydroxyethyl sulfone sulphate i loko o ke ʻano alkaline e hana i ka hui vinyl sulfone, a laila hui pū ʻia me ka fiber cellulose a loaʻa i ka hopena nucleophilic hoʻohui e hana i ka pilina covalent.
ʻO nā ʻano mea like ʻole ʻelua ma luna nei nā mea pena hoʻoheheʻe nui me ka huahana nui loa ma ka honua.I mea e hoʻomaikaʻi ai i ka helu hoʻopaʻa ʻana o nā mea hoʻoheheʻe reactive, ua hoʻokomo ʻia ʻelua mau pūʻulu reactive i loko o nā molekole dye i nā makahiki i hala iho nei, i kapa ʻia ʻo nā mea hoʻoheheʻe ʻelua.
Hiki ke hoʻokaʻawale ʻia nā dyes reactive i kekahi mau pūʻulu e like me kā lākou mau pūʻulu reactive ʻokoʻa:
1. Loaʻa i nā mea hoʻonaninani X-type nā pūʻulu ikaika dichloro-s-triazine, he mau mea hoʻonaninani haʻahaʻa haʻahaʻa, kūpono no ke kala ʻana i nā fiber cellulose ma 40-50 ℃
2. Loaʻa i nā mea hoʻoheheʻe K-type he pūʻulu monochlorotriazine reactive, kahi mea hoʻonaninani wela kiʻekiʻe, kūpono no ka paʻi ʻana a me ka hoʻoluʻu pad o nā lole pulupulu.
3. KN type reactive dye loa'a ka hydroxyethyl sulfone sulfate reactive hui, nona ka mea wela o ke ano o ka wai hooluu.ʻO ke ana wela 40-60 ℃, kūpono no ka waihoʻoluʻu ʻana i ka pulupulu roll dyeing, ka waihoʻoluʻu ʻana i ke anuanu, a me ka waihoʻoluʻu ʻana i ka paʻi anti-dye;kūpono hoʻi no ke kala ʻana i nā lole hemp.
4. Loa'a i nā mea ho'olu'u 'ano M-type nā pū'ulu ho'ohenehene 'elua a no nā mea ho'onanea 'ano wela wela.ʻO 60 ℃ ka mahana o ke kala.He kūpono ia no ka pulupulu a me ka lole olonā ka hoʻoluʻu a me ka paʻi ʻana.
5. Loa'a i nā mea ho'olu'olu ke 'ano KE 'ano pū'ulu ho'ohenehene 'elua a no ke 'ano wela ki'eki'e ka wai ho'olu'u, kūpono no ka pena 'ana i ka pulupulu a me ka lole olonā.Ka wikiwiki kala
