Top 10 Questions for Dye Expert Interview

1. What are the different types of dyes used in the textile industry?

• Acid Dyes: Used for dyeing wool, silk, and nylon. They are water-soluble and applied in an acidic environment.
• Basic Dyes: Used for dyeing cotton, linen, and paper. They are water-soluble and applied in a neutral or slightly alkaline environment.
• Direct Dyes: Used for dyeing cotton, linen, and rayon. They are water-soluble and applied directly to the fabric without the need for a mordant.
• Disperse Dyes: Used for dyeing synthetic fibers such as polyester and nylon. They are insoluble in water and are applied using a carrier solvent.
• Fiber-Reactive Dyes: Used for dyeing cotton, linen, and rayon. They react chemically with the fibers to form a covalent bond.
