Silk Dyeing
Silk is dyed using various dyes such as acid dyes, metal-complex, reactive dyes etc. Silk offers a wide colouration possibility covering almost the entire spectrum of colours and hues due to its ready acceptability for a large range of dyestuffs. The exceptional capacity to absorb moisture from the air, the comparatively simple and orderly arrangement of fibroin molecular structure, and the abundance of hydrogen bonds and electrostatic bonds render silk fibre an ideally suited substrate with a very good dye affinity.
