Dispersant or dispersing agent makes the dispersion process more stable and easier of solid material dispersed in liquid. Dispersing agent has effect on rate of dyeing. It increases the solubility of disperse dye as well as increases the dyeing rate up...
Before jumping into disperse dye, you have to understand the disperse dye definition. From the disperse dye definition, you will get to know about some basics of this dye. Then it will be easier for you to better understand the dye...
Dyeing of CDP with basic dye is a better choice in case of modified polyester. We all know that Disperse dye is used for polyester dyeing. But you will amaze to know that basic dye can also be used for polyester...
Dispersant or dispersing agent makes the dispersion process more stable and easier of solid material dispersed in liquid. Dispersing agent has an effect on the rate of dyeing. It increases the solubility of disperse dye as well as increases the dyeing...
Carrier method of dyeing for polyester fabric is done at atmospheric temperature with disperse dye. Disperse dyes are non-ionic in nature, almost insoluble and stay as finely divided aqueous dispersed form in water. These dyes have inherent affinity for polyester. In...
Polyester can be dyed in different method. Polyester fabric dyeing with high temperature is the best method that is basically followed in our industries. This process requires high temperature in between 130 -135℃. Also this requires high pressure up to 170...
For cellulosic material, reactive dye printing is an ideal process. But nowadays reactive dye is not only used in our conventional printing but also digital printing is carried out with reactive dye. In this article, we will discuss about reactive conventional...
Vat dye, one of the most important dye class, retains C=O chromophore in structure. This chromophore renders water insolubility. From an aqueous media, dyes are reduced and solubilized. In this state dyes show affinity for fibers. With higher strike rate, exhaustion...
Vat dyes are somewhat different from the other type of dyes. Because they are found in insoluble form. The dyeing procedure of vat dye is not as the same as the other dyes like reactive, direct, azoic, acid or basic dyes....
Acid dyes are mostly sulphuric or carboxylic acid salts and are essentially applied from an acidic bath and hence the name “acid dye”. Acid dyes have poor wash fastness but light fastness is quite good. Dyes possess affinity for protein fibers...
