What is a Dye?

A dye is a colored substance that chemically bonds to the material it is applied to. This process, known as dyeing, imparts color to the material, making it visually appealing. Dyes are typically used in an aqueous solution and require a mordant to improve the fastness of the dye on the fiber.

Key Characteristics of Dyes:

  • Solubility: Dyes are soluble in water or other solvents.
  • Affinity: They have an affinity for the material they color.
  • Fastness: Dyes resist fading or washing out.

Types of Dyes

Dyes are categorized based on their chemical structure and application method. Here are some common types:

1. Acid Dyes

Acid dyes are anionic dyes used on protein fibers like wool and silk. They are applied in acidic conditions to enhance bonding.

2. Basic Dyes

Basic dyes are cationic dyes used on acrylic and modified nylon. They offer bright colors but have poor light fastness.

3. Direct Dyes

Direct dyes are used on cellulose fibers like cotton. They have good wash fastness but require mordants for better results.

4. Reactive Dyes

Reactive dyes form a chemical bond with the fiber, providing excellent color fastness. They are commonly used on cotton and other cellulose fibers. — Zendaya And Tom Holland: Are They Still Together?

5. Vat Dyes

Vat dyes are insoluble dyes that are made soluble during the dyeing process. They are known for their excellent color fastness and are used on cotton and other cellulose fibers.

Uses of Dyes
