Study Notes

Chemicals and Dyes Used in Textile Industry

The textile industry relies heavily on dyes and chemicals to produce fabrics with desired colors, textures, and properties.

Sources of Dyes

Natural dyes are derived from plants, insects, and minerals, such as indigo, madder, and weld.
Synthetic dyes are manufactured from petroleum-based chemicals, offering a broader range of colors and higher colorfastness.

Uses of Dyes in Textile Industry

Dyes are used to impart color, aesthetic appeal, and functionality to fabrics, making them suitable for various applications.
Different types of dyes, such as acid, basic, mordant, and vat dyes, are used for specific fibers, like cotton, wool, and silk.
Dyes can also influence fabric properties, such as wrinkle resistance, water repellency, and UV protection.
