He kūlana hoʻoheheʻe maikaʻi loa ʻo Reactive Dyeing i ka wai.Ke hilinaʻi nui nei nā mea hoʻonanea i ka pūʻulu ʻakika sulfonic ma ka mole kala e hoʻoheheʻe ʻia i ka wai.No ka meso-temperature reactive dyes i loaʻa nā hui vinylsulfone, koe naʻe nā pūʻulu ʻakika sulfonic Eia kekahi, ʻo kāna β-ethylsulfone sulfate he hui hoʻoheheʻe maikaʻi loa.I loko o ka wai hoʻoheheʻe wai, ʻo nā ion sodium ma ka pūʻulu ʻakika sulfonic a me ka hui -ethylsulfone sulfate e hana i ka hopena hydration e hana ai ka wai i ka anion a hoʻoheheʻe ʻia i loko o ka wai.ʻO ka waihoʻoluʻu ʻana o nā mea hoʻoheheʻe reactive e hilinaʻi ʻia i nā ion maikaʻi ʻole o nā mea pena e hoʻoluʻu ʻia i ka fiber.ʻOi aku ka hoʻoheheʻe ʻana o nā mea hoʻonaninani reactive ma mua o 100 g/L.
He 200-400 g/l ka solubility o ka hapa nui o nā wai, a hiki i kekahi mau kala ke hiki i ka 450 g/l.
Akā i ke kaʻina hana kala, e emi ana ka solubility o ka wai ma muli o nā kumu like ʻole (a i ʻole hiki ke hoʻoheheʻe ʻia).
Ke emi ka solubility o ka wai, e hoʻololi kekahi hapa o ka wai mai ka ion maikaʻi ʻole hoʻokahi a hiki i nā ʻāpana, a e hoʻemi nui ʻia ka hoʻoiho ʻana ma waena o nā ʻāpana.
ʻO nā ʻāpana a me nā ʻāpana e huki kekahi i kekahi e hana i ka agglomeration
Ma kēia ʻano hoʻohuihui, ʻākoakoa nā ʻāpana kala i mau ʻāpana, a laila i ʻāpana, a hope i nā flocs.ʻOiai ʻo ka floc he hōʻiliʻili ʻoluʻolu, ma muli o ka papa pālua uila i hana ʻia e nā hoʻopiʻi maikaʻi a me nā hoʻopiʻi maikaʻi ʻole a puni ia, he paʻakikī i ka ikaika ʻoki o ka wai wai kala maʻamau e decompose ia, a ua maʻalahi ka floc ma ka lole.ʻO ka ua ma ka ʻili, ka hopena i ka ʻili a i ʻole ka ʻili.
Ke loaʻa ka hoʻohuihui like ʻana o ka wai, e emi ana ka wikiwiki o ka waihoʻoluʻu, a e hoʻoulu ʻia nā ʻokoʻa o nā ʻili, nā ʻili, a me nā ʻili.No kekahi mau mea hoʻonanea, e hoʻolalelale nā flocs i ka hui ʻana ma lalo o ka ikaika ʻoki o ka wai ʻona, e hoʻomaloʻo ai a paʻakai.Ke pau ka paʻakai, e māmā loa ka waihoʻoluʻu, a ʻaʻole hoʻi i hoʻoluʻu ʻia, ʻoiai inā i hoʻoluʻu ʻia, e lilo ia i mau ʻeleʻele koʻikoʻi a me nā pila.
Hoʻoluʻu Waikani
ʻO nā kumu o ka hoʻohui ʻana i ke kala
ʻO ke kumu nui ka electrolyte.I ke kaʻina hana kala, ʻo ka electrolyte nui ka dye accelerant (sodium sulphate powder a me ka paʻakai).Aia i loko o ka mea hoʻoheheʻe wai i nā ion sodium, a ʻoi aku ka haʻahaʻa o ka ion sodium i loko o ka mole kala ma mua o ka mea o ka accelerant wai.ʻO ka helu like o nā ion sodium a me ka ʻike maʻamau o ka accelerator i ka wā o ke kaʻina hana kala maʻamau, ʻaʻole ia e pili nui i ka solubility o ka wai i loko o ka ʻauʻau wai.
Eia nō naʻe, ke piʻi aʻe ka nui o ka mea hoʻonaninani hoʻonaninani, hoʻonui pū ka ʻike o nā ion sodium i ka hopena.ʻO ka nui o ka sodium iions e keʻakeʻa i ka ionization o nā ion sodium ma luna o nā pūʻulu i hoʻoheheʻe ʻia o nā molekala wai, a laila e hōʻemi i ka solubility o ka wai.
Ke ʻoi aku ka nui o ka hoʻopaʻa ʻana o ka mea hoʻoheheʻe kala ma mua o 200 g/L, e loaʻa ka hapa nui o nā kala i nā degere like ʻole o ka hōʻuluʻulu ʻana.
Ke ʻoi aku ka nui o ka hoʻopaʻa ʻana o ka mea hoʻoheheʻe kala ma mua o 200 g/L, e loaʻa ka hapa nui o nā kala i nā degere like ʻole o ka hōʻuluʻulu ʻana.
Ke ʻoi aku ka nui o ka mea hoʻolalelale i ka 250 g/L, e hoʻoikaika ʻia ke kiʻekiʻe o ka agglomeration, e hana mua i nā agglomerates, a laila e hana koke i nā agglomerates a me nā floccules ma lalo o ka ikaika shear of the dye solution.No kekahi mau wai waihoʻoluʻu me ka haʻahaʻa haʻahaʻa, ua paʻakai ʻia kekahi hapa o ia mea a maloʻo hoʻi.
He ʻokoʻa ka pale ʻana i ka hoʻohui ʻana a me ka paʻakai ʻana i nā wai waihoʻoluʻu me nā ʻano molekala like ʻole.ʻO ka haʻahaʻa o ka solubility, ʻoi aku ka maikaʻi o ka anti-aggregation a me ka paʻakai paʻakai.
Hoʻoholo nui ʻia ka solubility o ka wai e ka helu o nā pūʻulu waikawa sulfonic i loko o ka mole kala a me ka helu o β-ethylsulfone sulfates.
I ka manawa like, ʻoi aku ka nui o ka hydrophilicity o ka mole kala, ʻoi aku ka kiʻekiʻe o ka solubility, a me ka haʻahaʻa o ka hydrophilicity, ʻoi aku ka haʻahaʻa o ka solubility.(ʻO ka laʻana, ʻoi aku ka hydrophilic o nā wai me ka hoʻolālā azo ma mua o nā wai me kahi ʻano heterocyclic.) Eia kekahi, ʻoi aku ka nui o ka molecular structure o ka wai, ʻoi aku ka haʻahaʻa o ka solubility, a me ka liʻiliʻi o ka molecular structure, ʻoi aku ka kiʻekiʻe o ka solubility.
ʻO mākou kahi mea hoʻolako Reactive Dyeing.Inā he koi kāu no kā mākou huahana, e ʻoluʻolu e kelepona mai iā mākou.
