Acid Dyes

Acid Dyes for Leather Acid dyes are considered very appropriate for the purpose of dyeing leather. This is due to the fact that these dyes can penetrate leather better than other types of dyes.

The acid dyes are usually applied under acidic conditions. The application of acid dyes on wool or nylon results in ionic bond or salt links between the anionic dye and the positively charged groups in the fiber under acidic conditions. In addition to ionic bonds, hydrogen bonds as well as Van der Waal’s forces may also be formed between the fiber polymer system and the acid dye molecules.

Acid Dyes Uses

Acid dyes have a variety of different uses. They are used in many different industries and sectors for various types of applications.

A few textile applications and uses according to the type of dye:

Fast Acid Dyes :

Used for dyeing or colouring non-washable knitting yarns, carpet yarns and piece goods. It is possible that a few pale-medium shades of fast acid dyes may be able to be hand washed.

Super Milling Dyes :

These can be used to impart bright shades onto products or materials like loose stock, sliver, and yarns that need high wet fastness. They can also be used to impart pale-medium shades that can be machine-washed.

Acid Levelling Dyes :

Such dyes can be used to dye or impart colour onto materials like carpet yarn, woollen and worsted fabrics, and such textile products that do not need washing and perspiration fastness.

Acid Milling Dyes :

This type of acid dye can be used to impart medium-heavy bright shades on products like piece goods and materials like carpet yarns, knitting yarns, and weaving yarns.

Metal Complex Dyes :

Due to their fastness properties, these acid dyes are used to dye womenswear and hosiery and other materials like leather, wood, metals, plastics, etc.

Applications

Acid dyes have a variety of different uses. They are used in many different industries and sectors for various types of applications.

A few textile applications and uses according to the type of dye:

Medical Industry :

Acid dyes are used in the field of Histology for the purposes of research or diagnosis. They are used to stain or colour basic tissue proteins in microscopic examinations.

Food Industry :

Acid dyes are used as food colouring in the food industry. They must be approved as being eligible for consumption before use. They are used in bread, condiments, frosting, etc.

Leather Colouration :

Due to acid dyes being resistant to migration, they are ideal to colour leather. Usually, all types of acid milling dyes and metal complex dyes are applicable here.

Dyeing of Fur Skins :

Due to a few of their properties like fastness, good exhaustion and combinability at 60 to 65 °C, and being able to impart only a light stain as well as trichromatic shades, acid dyes are good for fur skin dyeing.

Dyeing of Double Weave Cloths :

One of the dyes used to impart colour only double cloths are metal complex non-bleeding dyes. Double weave cloths or just double cloths are a type of woven textile where different sets of materials like sheep skins, weft yarns, etc are interconnected to form 2 layered cloths.

Wood Staining and Coating :

Wood is stained with colour to make it more attractive or to add colour to it. They can be stained in natural wood tones or another colour entirely. For this staining process, generally solvent soluble acid dyes are used. Acid dyes like metal complex dyes are also used to coat stained wood to increase durability and protection.

Fast Acid Dyes :

Used for dyeing or colouring non-washable knitting yarns, carpet yarns and piece goods. It is possible that a few pale-medium shades of fast acid dyes may be able to be hand washed.

Ink Formulation :

Acid dyes can also be used to make ink for different uses like ink-jet printers, ink pads, ink for ball pens, ink for markers, etc. coloured ink in trichromatic form can also be made.

Jute Dyeing :

Jute fabrics and fibres are generally highly demanded to be bright, wash fast and light fast. For this reason, acid dyes with good light fastness properties are used to dye jute.
