The discovery and invention of any thing has its contingency and inevitability. The invention of reactive dyes also has inevitable accidents. Since the release of the first reactive dyes, it has been 60 years old. In these 60 years, reactive dyes To make the color of textile printing become colorful; reactive dyes have changed the color of the world.
Missing with reactive dyes
Ciba: In 1923, Ciba found that the acid monochlorotriazine dye was used for dyeing wool and in 1953 invented the Cibalan Brill dye.
IG: In 1932, IG dyed wool with Supraamine Orange R of chloroacetamide.
Hearst: A azo dye of the β-sulfate ethyl sulfone group was produced in 1949.
First reactive dye patent
In 1954, IDRattee and WEStephen of the Imperial Chemical Industry (ICI) discovered that the dichloro-triazine dye was covalently bonded to cellulose fibers under alkaline conditions, so the application was made. The first reactive dye patent.
Ps: I have to say about British Imperial Chemistry (ICI), founded in 1926, the UK's largest chemical producer, one of the world's largest chemical monopoly groups. Everyone may not be familiar with ICI, but everyone should be familiar with it. As early as the beginning of the 19th century, ICI came to Shanghai to open a foreign bank, the name is Bu Nemen. In 1993, ICI's dye division was reorganized into the company. Then BASF acquired the dye division of Bu Nemen-Jerikang, and then in October 2000, DyStar acquired BASF's dye division. Finally, everyone knows that in 2010 China Longsheng acquired DyStar dyes. . (There are too many questions, sorry! Continue to talk down)
First reactive dye commodity
60 years ago, the British ICI company officially released the first reactive dyes in 1956, the international dye index number: C.I. Reactive Red 1. Dye trade name: Procion RED MX-2B. The dye brand is also Puschian, and then the world of reactive dyes begins.
Classic dye brand
After ICI released the reactive dyes in the UK, Ciba and Hearst couldn't sit still. The dyes that they found to dye wool could be covalently reacted with cellulose fibers through alkaline treatment. Therefore, the classic dye brand was born. Up:
Remazol: In 1958, Hearst successfully used vinylsulfone-based reactive dyes for the dyeing of cellulose fibers, called Remazol dyes. This classic dye is now owned by DyStar.
Cibacron: In 1958, Ciba named its reactive dye Cibacron, now owned by Huntsman.
Drimarene: In 1959 Sandax and the dye that officially produced another reactive group, the trichloropyrimidine type, named Drimarene, Clariant's classic dye brand, now Returned to the company.
History of reactive dyes in China
China began researching reactive dyes in 1957 and developed the first reactive dye on January 1, 1958, synchronizing with the world! In April 1958, Chen Zhizhen of Shanghai Taixing Dyestuff Factory successfully developed cyanuric chloride. In 1959, Cheng Lubo of Dalian Institute of Technology and Zhu Zhenghua of East China Institute of Chemical Technology successfully developed β-sulfate ethyl sulfone, which was quickly put into production. Shanghai Dyeing Eight Factory became the earliest professional factory for reactive dye production in China!
