Chidule chachidule cha utoto wa reactive
Zaka zoposa 100 zapitazo, anthu ankakhulupirira kuti apanga utoto umene ungagwirizane ndi ulusi, ndipo zimenezi zimathandiza kuti nsalu zotayidwa zikhale zochapira bwino.Mpaka 1954, Raitee ndi Stephen a Bnemen Company adapeza kuti utoto womwe uli ndi gulu la dichloro-s-triazine ukhoza kugwirizana kwambiri ndi magulu oyambira a hydroxyl pa cellulose pansi pamikhalidwe yamchere Pamodzi, kenako kudayidwa mwamphamvu pa ulusi, pali gulu la utoto wokhazikika womwe ungathe. kupanga covalent zomangira ndi ulusi kudzera chemical reaction, amatchedwanso reactive dyes.Kutuluka kwa utoto wokhazikika kwatsegula tsamba latsopano la mbiri yachitukuko cha utoto.
Chiyambireni kupangidwa kwa utoto wokhazikika mu 1956, kukula kwake kwakhala kotsogola.Pakali pano, utoto wapachaka umatulutsa ulusi wa cellulose padziko lonse lapansi umapanga zoposa 20% za utoto uliwonse womwe umatulutsa pachaka.Udaya wokhazikika ukhoza kukula mwachangu chifukwa cha izi:
1. Utoto ukhoza kuchitapo kanthu ndi ulusi kuti upange mgwirizano wolumikizana.M'mikhalidwe yabwinobwino, mgwirizano woterewu sudzasiyanitsidwa, kotero utoto wokhazikika ukadayidwa pa ulusi, umakhala ndi mphamvu yodaya bwino, makamaka yonyowa.Kuphatikiza apo, pambuyo popaka utoto ulusiwo, sudzavutitsidwa ndi kuwala kopepuka ngati utoto wina wa vat.
2. Ili ndi magwiridwe antchito abwino kwambiri, mtundu wowala, kuwala kwabwino, kugwiritsa ntchito bwino, chromatography yathunthu, komanso mtengo wotsika.
3. Ikhoza kupangidwa kale ku China ndipo imatha kukwaniritsa zofunikira zamakampani osindikizira ndi opaka utoto;ntchito zake zambiri sizingagwiritsidwe ntchito popaka utoto wa ulusi wa cellulose, komanso utoto wa ulusi wa mapuloteni ndi nsalu zina zosakanikirana.
Mbiri ya utoto wokhazikika
Kuyambira zaka za m'ma 1920, Ciba yayamba kufufuza za utoto wa cyanuric, womwe umagwira ntchito bwino kuposa mitundu yonse yachindunji, makamaka Chloratine Fast Blue 8G.Ndi kuphatikiza kwa molekyulu yamkati yopangidwa ndi utoto wabuluu wokhala ndi gulu la amine ndi utoto wachikasu wokhala ndi mphete ya cyaniric mumtundu wobiriwira, ndiye kuti utotowo uli ndi atomu ya klorini yosalowa m'malo, ndipo pansi pazifukwa zina, imatha The element. zomwe zinapanga mgwirizano wogwirizana, koma sizinazindikiridwe panthawiyo.
Mu 1923, Ciba anapeza kuti utoto wa asidi wotchedwa monochlorotriazine wopaka ubweya, umene umatha kunyowa kwambiri, choncho mu 1953 anapanga utoto wamtundu wa Cibalan Brill.Nthawi yomweyo, mu 1952, Hearst adapanganso Remalan, utoto wokhazikika waubweya, pamaziko owerengera magulu a vinyl sulfone.Koma mitundu iwiri ya utotoyi sinali yopambana kwambiri panthawiyo.Mu 1956 Bu Neimen pomalizira pake adatulutsa utoto woyamba wa thonje, wotchedwa Procion, womwe tsopano ndi utoto wa dichloro-triazine.
Mu 1957, Benemen anapanga utoto wina wa monochlorotriazine, wotchedwa Procion H.
Mu 1958, Hearst Corporation idagwiritsa ntchito bwino utoto wa vinyl sulfone-based reactive dyes popaka ulusi wa cellulose, wotchedwa Remazol dyes.
Mu 1959, Sandoz ndi Cargill anatulutsa mwalamulo utoto wina wa gulu, womwe ndi trichloropyrimidine.Mu 1971, pamaziko awa, ntchito yabwino ya utoto wa difluorochloropyrimidine idapangidwa.Mu 1966, Ciba anapanga utoto wonyezimira wozikidwa pa a-bromoacrylamide, umene umagwira ntchito bwino pa utoto wa ubweya, umene unayala maziko ogwiritsira ntchito utoto wothamanga kwambiri paubweya m’tsogolo.
Mu 1972 ku Baidu, a Benemen adapanga utoto wokhala ndi magulu awiri osinthika, omwe ndi Procion HE, pamaziko a utoto wamtundu wa monochlorotriazine.Utoto wamtunduwu wapita patsogolo kwambiri potengera kuyambiranso kwake ndi ulusi wa thonje, kuchuluka kwa fixation ndi zina.
Mu 1976, Buneimen adapanga gulu la utoto wokhala ndi magulu a phosphonic acid monga gulu logwira ntchito.Ikhoza kupanga mgwirizano wa covalent ndi ulusi wa cellulose pansi pa zinthu zopanda alkali, makamaka zoyenera kupaka utoto ndi utoto wobalalika mu kusamba komweko Kusindikiza kwa phala komweko, dzina la malonda ndi Pushian T. Mu 1980, kutengera utoto wa vinyl sulfone Sumifix, Sumitomo. Corporation of Japan idapanga utoto wamagulu a vinyl sulfone ndi monochlorotriazine double reactive group.
Mu 1984, Nippon Kayaku Corporation inapanga utoto wokhazikika wotchedwa Kayasalon, womwe unawonjezera nicotinic acid m'malo mwa mphete ya triazine.Imatha kuchitapo kanthu molumikizana ndi ulusi wa cellulose pansi pa kutentha kwambiri komanso kusalowerera ndale, kotero ndiyoyenera kuyika nsalu za polyester / thonje zosakanikirana ndi kutentha kwambiri komanso kuthamanga kwambiri njira imodzi yopaka utoto yobalalitsa / utoto wokhazikika.

Mapangidwe a utoto wokhazikika
Reactive dyeing supplier amakhulupirira kuti kusiyana kwakukulu pakati pa utoto wotakataka ndi mitundu ina ya utoto ndikuti mamolekyu awo amakhala ndi magulu omwe amatha kulumikizana ndi magulu ena a ulusi (hydroxyl, amino) kudzera mu reaction yamankhwala Otchedwa reactive gulu).Mapangidwe a utoto wokhazikika amatha kuwonetsedwa ndi njira iyi: S－D－B－Re
Mu chilinganizo: S-madzi sungunuka gulu, monga sulfonic asidi gulu;
D——Dye matrix;
B——Gulu logwirizanitsa pakati pa utoto wa makolo ndi gulu logwira ntchito;
Gulu loyambiranso.
Nthawi zambiri, kugwiritsa ntchito utoto wokhazikika paulusi wansalu kuyenera kukhala ndi izi:
Kusungunuka kwamadzi kwakukulu, kukhazikika kwakukulu kosungirako, kosavuta ku hydrolyze;
Lili ndi reactivity mkulu kwa CHIKWANGWANI ndi mkulu kukonza mlingo;
Kugwirizana kwa mankhwala pakati pa utoto ndi fiber kumakhala ndi kukhazikika kwa mankhwala, ndiko kuti, chomangiracho sichophweka kutha panthawi yogwiritsira ntchito;
Diffusability wabwino, utoto wabwino wa mulingo komanso kulowa kwa utoto wabwino;
Kuthamanga kosiyanasiyana kodaya, monga kuwala kwa dzuwa, nyengo, kuchapa, kupaka, kukana kutsuka kwa chlorine, ndi zina.
Utoto wosasunthika ndi utoto wa hydrolyzed ndi wosavuta kutsuka mutapaka utoto, osadetsa;
Kudaya ndikwabwino, kumatha kudayidwa mwakuya ndi mdima;
Zomwe zili pamwambazi zimagwirizana kwambiri ndi magulu ogwira ntchito, otsogolera utoto, magulu osungunuka m'madzi, ndi zina zotero. Pakati pawo, magulu ochitapo kanthu ndi maziko a utoto wokhazikika, womwe umasonyeza magulu akuluakulu ndi katundu wa utoto wosungunuka.
