Nomenclature of Dyes

In order to meet the requirements of production and application, the correct color and application performance of reactive dyes must be given special names for dyes.



The name of a dye often contains three parts, namely the title part, the color part, and the application identification part. The title part indicates the application category of the dye. The trade name or application category of the dye in the world represents the title of the dye, and the application category or property of the dye is used as the title in China.


The title of China's printing and dyeing dyes

There are 31 kinds of dyes in China, such as acid, acid complex, acid medium, neutral, direct, direct lightfast, direct blending, alkaline, cationic, active, reduction, soluble reduction, vulcanization, vulcanization reduction, dispersion, color Phenol, color base, color salt, polycondensation, fast pigment, etc.

The color part indicates the color of the dye on the fiber, which is basically the same at home and abroad.

my country has adopted 29 color names and 3 color adjectives:

Bright yellow, yellow, golden, dark yellow, orange, scarlet, red, pink, rose red, magenta, red purple, claret, purple, turquoise blue, blue, lake blue, brilliant blue, dark blue, green, brilliant green, dark green , Yellow brown, red brown, brown, dark brown, olive green, grass green, gray, black.


The application identification part uses letters to indicate shade, traits, application performance, etc. The meaning of commonly used letters has three aspects.

One.Indicates the quality of dye shade or color

A. The customary name code of the dye, such as lake blue A, acid scarlet A.

B means blue or cyan light

G means yellow or green light

R means red light

F means pure shade

D means dark or darker shade

T means dark

V means purple light

Y means yellow light

O means orange light

J means green light or yellow light


Two:Indicates the nature and purpose

AS insoluble azo dye naphthol series name, such as AS-D, etc.

B Double-s-triazine dyes, such as Megafix golden BES etc.

C means chlorine bleaching resistance, such as Vat Blue BC, used for cotton; insoluble azo dye hydrochloride, such as yellow base GC.

D is suitable for dyeing, high-temperature-resistant blended direct dyes, such as direct blended yellow D-RL; high-temperature disperse dyes, such as Dispersol orange D-G, can print vat dyes, such as vat brown RRD.

E E-type disperse dyes with good levelling properties, such as disperse yellow SE-RGFL; exhaustion dyes, such as Megafix yellow BES; expresses a deep color, such as vat blue ER.

Ex means high concentration.

F Fast color, such as disperse red FB; bright color, such as cationic pink

FG; Difluoro-chloropyrimidine reactive dyes, such as Reactive Red F-3B; means that the dye particles are fine, which means new.

H means good heat dyeing or heat resistance. Thermosetting reactive dyes, such as Pursian Violet H-3R; high temperature disperse dyes, such as Disperse Scarlet HBGL; suitable for dyeing cotton and wool interwoven fabrics; Ashlin class fastness, such as soluble vat orange HR; reactive dyes that are resistant to alkali hydrolysis .

HE has good dye exhaustion. Dichloro-s-triazine reactive dyes, such as Pushan Green H-E4BD I, are equivalent to the fastness of vat dyes, such as chromol AS-ITR, red base ITR, soluble vat blue IBC; the matrix is reduced Dyes, such as soluble vat orange IRK.

K thermosetting reactive dyes, such as reactive turquoise blue K-GL; vat dye cold dyeing methods, such as vat golden GK.

KD high temperature direct reactive dyes, such as reactive yellow KD-3G.

KE Dichloro-s-triazine reactive dyes, such as reactive brilliant red KE-3B KP Dichloro-s-triazine reactive dyes for printing, such as reactive blue KP-BR

KM is suitable for reactive dyes for high temperature dip dyeing, such as reactive bright yellow KM-7GKN vinyl sulfone reactive dyes, such as reactive brilliant blue KN-R


L Excellent light fastness, such as direct light fastness turquoise blue GL; low-temperature disperse dyes, such as Shangdaron yellow LR; bright and bright colors, such as cationic brilliant blue X-GRLL; leather spray dyes, such as leather spray yellow GL, etc.; dye uniform Good dyeability, suitable for dyeing hemp, indicating the solubility of the dye.

LL has excellent light fastness, such as cationic bright yellow X-7GLL.

M color matching dye; mixed reactive dyes with double reactive groups, such as reactive bright yellow M-7G; medium temperature disperse dyes, such as disperse yellow M-FL; excellent migration.

M type cationic dyes, such as cationic red M-RL; dimensional cotton blended fabric dyes, such as cobalt blue and black M-2G. MX common reactive dyes, such as Pushan Yellow MX-6G.

N standard dyeing method, such as vat blue RSN; standard strength, such as vat blue BCSN; dyes with similar application properties and the same chemical structure, such as reactive brilliant red K-2GN; indicating new or special shades that do not match the standard color card; black light.

O is derived from indigo, such as soluble reduced blue O4B obtained with bromoindigo; high concentration, such as acid mordant dark blue AGLO.

P For printing, such as reactive brilliant red K-2BP; reactive dyes containing phosphoric acid groups, such as reactive red

P-2B; paper dye; has good perspiration fastness, such as reactive turquoise blue K-GP; suspension pad dyeing vat dye; pure.

S high temperature type disperse dyes have high biochemical fastness, such as disperse dark blue S-GL; standard strength, such as Mikenthen blue BCS; dyeing silk, such as weak acid orange GS; easy to dissolve, excellent solubility; sulfate. SE medium-temperature disperse dyes, such as disperse yellow SE-FL.

T deep, such as disperse yellow T; disperse dyes for dyeing polyester-cotton blended fabrics, such as

Shangdablend Orange T-B; Reactive dyes containing phosphoric acid groups, such as Pushan Yellow T-4G.

U Dyes for blending or interlaced fabrics.

W Dyeing wool fabrics, such as weak acid brilliant blue GAW; can dye blended fabrics.
