Introduction The dyes containing azo groups – N = N – are called Azoic Dye. These are not ready made dyes but are produced by reaction of two components – Diazocomponent or Base/Salt and coupling component (Napthol). Azoic dye also named as Napthol, Branthol, Magic and Ice color. Dye formation in fiber occurs on the basis of[…]
The textile industries dye polyester yarn or fabric use disperse dye for its versatile color. The dyes are hydrophobic, so the dispersing agent is required to spread the dye onto the yarn or fabric surface. Here high temperature and pressure are also required to fix the dye particles into the fibre molecules. The dyes hold[…]
Definition of Disperse Dye The term ‘Disperse dye’ is an organic coloring substance which is free from ionizing group are of low water solubility and are suitable for dyeing hydrophobic textile materials from colloid dispersion. It has low molecular weight and derivatives of Azo, Anthra – quinine, Di phynile amine and other component. Properties of[…]
Reactive dyes are special coloring agents that textile industries use for dyeing fibre, yarn, fabrics, and garments. These dyes are popular in the textile industry because they make colors that fix well and don’t fade quickly. Unlike other dyes that fix on the fabric’s surface, reactive dyes combine with the fabric’s molecules through a chemical[…]
Definition of Reactive Dye Reactive dyes are a class of colored compounds that chemically bind to fibers like cotton, rayon, or linen to impart color resistance to washing and fading. To apply reactive dyes properly, we need a process with controlled conditions. Usually, they are used in an alkaline bath with sodium carbonate or sodium[…]
