A Acid Dye - It is applied to polyamide fibers from acidic solutions. Essentially a synthetic dye, it is used for dyeing of silk, wool and nylon.
Affinity - In dyeing field, affinity means preferential attraction of dye towards fiber other than for solution of dye bath. With dye having strong affinity, it easily leaves dye solution of dispersion and gets attached to fiber that is put for dyeing process.
Aniline - Aniline is commonly used term in synthesis of dyes. With chemical formula of C6H7N, it is known as aniline oil and finds usage as a synonym for synthetic dyes.
Azo - Azo refers to chemical compound containing double nitrogen atoms with double bond between them (-N=N-). These dyes form largest group of dyes and display stability, strength, light-fastness and also respond well to mixing. Azo dyes can be found among dye classes of direct, acid, basic, reactive and disperse.
B Basic Dye - Generally Basic dyes are cationic dyes that are able to react with acidic groups on fibers.
Bi-Functional Reactive Dye - These dyes have in them the potential to react with fiber in more than a single way.
Binder - It is a colorless material which is used to attach pigment to fabric. Binders act like "glues" and help in holding the pigment in place. Some popular examples include paints that have pigments mixed with binders.
C Cation - it is a positively charged ion. A large number of chemicals that find application in textile processing are referred as cationic.
Cellulose - It is a polymer comprising of large numbers of units with each having general formula represented by C6H10O5.
Chromophore - It is a color-bearing compound that has special properties which is found in organic molecule that makes it appear colored.
Colour Index - It is a publication that is jointly introduced by Society of Dyers and Colorists of Great Britain and American Association of Textile Chemists and Colorists.
Chrome - It is any salt of chromium which finds usage in tanning and dyeing process.
D Direct Application - It’s a method which is used for describing process where solution of dye is locally applied to different fabric areas like painting, squirting, spraying, stamping
Direct Dye - It is a dye which is carried out by immersing fiber in dye solution without any need of other chemicals for bonding dye to fibers.
Disperse Dye - These dyes are found in dye bath as kind of suspension/dispersion of microscopic particles and have only a minuscule amount in true solution at any given moment of time.
E Enzyme - These are type of protein that are presently popularly used in the field of textile processing. These perform role of catalyst in biochemical reaction. Some of popular examples include Amylase - applied for de-sizing and Cellulose - Used in modification of cellulosic fabrics.
Exhaust Dyeing - This type of dyeing finds usage in denoting application of dye bath of moderately larger liquor to goods ratio in a situation where fiber is immersed for a while. It allows dye molecules to exit bath and get attached to fibers.
