These dyes have better fastness properties than levelling acid dyes, and have reasonable wet fastness, particularly if alkaline milling is to take place in a subsequent process. Super milling acid, or neutral dyeing, dyes are applied in a similar way to milling acid dyes, except that greater control over the strike rate of the dye is exercised.
Dyeing is the application of dyes or pigments on textile materials such as fibers, yarns, and fabrics with the goal of achieving color with desired color fastness.Dyeing is normally done in a special solution containing dyes and particular chemical material. Dye molecules are fixed to the fibre by absorption, diffusion, or bonding with temperature and time being key controlling factors.

The indigo dye product itself is highly sustainable; it is safe enough to be widely used as a food colorant. However, the indigo dyeing process is criticized for poor sustainability, primarily because sulfur reducing compounds and large amounts of problematic wastewater are still required with current dyeing methods.

Don't waste your time and money using the improper dye type, our guide will walk you through everything.
The process of using acid dyes predominantly takes place in water, when the acid dye is dissolved and therefore able to interact with the material being colored. Historically, acid dyes were most commonly used to dye materials consisting of protein fibers. The acidic pH of the dye-bath allows the dye molecules to bond to the protein fibers.
Dyeing and printing processes are value-added treatments for most textile materials. A dyeing process is the interaction between a dye and a fibre, as well as the movement of dye into the internal part of the fibre. Generally, a dyeing process involves adsorption (transfer of dyes from the aqueous solution onto the fibre surface) and diffusion (dyes diffused into the fibre).
Aug 23, 2013· Milling acid dyes; Super-milling acid dyes.

Combined in trichromatic shades, the items dyed with leveling acid dyes should not be machine dyed or washed in warm water. Instead, the washing needs to be done in cool water through dry-cleaned/hand washed process. Milling Acid Dyes : Mainly used for self shading, wet fastness of these dyes is available in medium to high range.
In fact, mordant dyes are often referred to as chrome dyes. The metal in pre-metallised dyes is incorporated into the dye molecule during the manufacturing process. Acid dyes are usually sodium salts of sulphonic acids, or less frequently of carboxylic acids, and are therefore anionic in aqueous solution. They will dye fibres with cationic sites.
