Typical Dyeing Recipe for Different Fibers and Dyes

Dyeing in textile is the process of coloration to textile materials like fibers, yarns, and fabrics. In this process different types of dyes and chemicals are used to produce different shades at different types of fabric. This process can be done by hand or by machine. Various types of dyeing recipe are used for different types of fiber. In this article I have given 6 typical recipes for different dyes and fibers.
