Mbiri ya Reactive Dyes

Ciba anayamba kuphunzira za utoto wa melamine m’zaka za m’ma 1920.Kuchita kwa utoto wa melamine ndikwabwinoko kuposa utoto wonse wachindunji, makamaka Chloramine Fast Blue 8G.Ndi utoto wabuluu wopangidwa ndi mamolekyu omangiriza omwe ali ndi gulu la amine ndi utoto wachikasu wokhala ndi mphete ya cyanuryl kuti apange kamvekedwe kobiriwira, ndiye kuti utotowo uli ndi maatomu a klorini osalowa m'malo, ndipo pansi pazifukwa zina, Imatha kuchitapo kanthu popanga zinthu zolumikizana. , koma sichidziwika.

Mu 1923, Ciba anapeza kuti utoto wa asidi-chlorotriazine umapaka ubweya wa ubweya kuti ukhale wonyowa kwambiri, choncho mu 1953, anatulukira utoto wa mtundu wa Ciba Lambrill.Nthawi yomweyo, mu 1952, Hirst adapanganso Remalan, utoto wokhazikika waubweya, potengera kafukufuku wamagulu a vinyl sulfone.Koma mitundu iwiriyi sinali bwino kwambiri panthawiyo.Mu 1956, Buneimen pomalizira pake adatulutsa utoto woyamba wa Procion wa thonje, womwe tsopano ndi utoto wa dichlorotriazine.

Mu 1957, Benemen adapanga utoto wina wa monochlorotriazine, Procion H.

Mu 1958, Hearst adagwiritsa ntchito bwino utoto wa vinylsulfone-based reactive dyes popaka ulusi wa cellulose, womwe ndi utoto wa Remazol.

Mu 1959, Sandoz ndi Cargill anatulutsa mwalamulo utoto wina wa gulu, trichloropyrimidine.Mu 1971, pamaziko awa, utoto wokhazikika wa difluorochloropyrimidine wokhala ndi ntchito yabwinoko unapangidwa.Mu 1966, Ciba adapanga utoto wokhazikika wotengera a-bromoacrylamide, womwe uli ndi zida zabwino zodaya paubweya ndikuyika maziko ogwiritsira ntchito utoto wothamanga kwambiri paubweya m'tsogolo.

Mu 1972, ku Baidu, a Benemen adapanga utoto wokhala ndi magulu awiri okhazikika otengera utoto wa monochlorotriazine, womwe ndi Procion HE.Utoto udawongoleredwa mopitilira muyeso wa reactivity ndi ulusi wa thonje komanso kuchuluka kwa fixation.

Mu 1976, Bunaimen adapanga kalasi ya utoto wokhala ndi magulu a phosphonic acid monga magulu okangalika.Ikhoza kupanga mgwirizano wa covalent ndi ulusi wa cellulose pansi pa mikhalidwe yopanda alkali, ndipo ndi yoyenera makamaka kusindikiza phala la kusamba, lomwe ndilofanana ndi kufalitsa utoto wa utoto.Dzina la malonda ndi Pushian t.Mu 1980, kutengera utoto wa vinyl sulfone Sumifix, Sumitomo Corporation yaku Japan idapanga vinyl sulfone Ndi utoto wamtundu wa monochlorotriazine wapawiri.

Mu 1984, Kampani ya Nippon Kayaku idapanga utoto wowoneka bwino wotchedwa Kayasalon, womwe udawonjezera cholowa m'malo mwa mphete ya triazine.Imatha kuchita mogwirizana ndi ulusi wa cellulose pansi pa kutentha kwambiri komanso kusalowerera ndale, ndipo ndiyoyenera kutentha kwambiri komanso kutulutsa kwamphamvu kwambiri / utoto wothira utoto wopaka utoto umodzi wansalu zophatikizika ndi thonje la polyester.

Ndife Reactive Dyes Suppliers.Ngati muli ndi chidwi ndi katundu wathu, chonde omasuka kulankhula nafe.
