An acid dye is a dye that is typically applied to a textile at low pH. They are mainly used to dye wool, not cotton fabrics. [1] Some acid dyes are used as food colorants, [2] [3] and some can also be used to stain organelles in the medical field. Acid dyes are anionic, soluble in water and are essentially applied from acidic bath.
This range contains a mixture of 3 different dyes - direct, acid and disperse. Direct dyes are for cellulose based fabrics, acid dyes for wool and nylon and disperse for some plastics. None of these are reactive dyes and are less wash fast than the other ranges. It comes in 26 colours. [3]

These dyes, which are chemically similar to vat dyes, are developed by light instead of being applied in an oxygen-free bath and being developed in the fabric by exposure to oxygen. Inkodyes are true dyes, not fabric paints. A dye itself attaches to the fabric; fabric paint includes a glue-like binder, which imparts a stiffer feeling to the fabric.
Its chemical name is 1-(4-sulfo-1-napthylazo)-2-napthol-6,8-disulfonic acid, trisodium salt. Ponceau (17th century French for " poppy-coloured ") is the generic name for a family of azo dyes . Ponceau 4R is a strawberry red azo dye which can be used in a variety of food products, and is usually synthesized from aromatic hydrocarbons ; it is ...
Different classes of dyes are used for different types of fiber and at different stages of the textile production process, from loose fibers through yarn and cloth to complete garments. Acrylic fibers are dyed with basic dyes, while nylon and protein fibers such as wool and silk are dyed with acid dyes, and polyester yarn is dyed with dispersed ...
Martius yellow is an organic compound that once was used to protect wool from moths. It is prepared by nitration of naphthol. [1]Martius yellow stains have been used to stain erythrocytes yellow so that they contrast well with red fibrin in trichrome staining methods such as Lendrum's Picro Mallory and Slidder's Martius, Scarlet and Blue (MSB).
