The dyeing of cellulosic, protein, polyamide, polyester and acrylic fibres is outlined, along with the application of fluorescent brightening agents and the treatment of fibre blends. Machinery for the dyeing of fibre, yarn, fabrics and garments is also considered.

Which is the largest class of textile dyes?

They are water-soluble anionic compounds. This class of dyes is the largest dye class and used extnesively on cellulosics (cotton) when bright shades are desired. They can be very well applied to nylon, silk and wool. The auxiliaries required are sodium chloride, urea, sodium carbonate, caustic soda and buffers.

How are dyes different from natural and synthetic dyes?

CLASSIFICATION OF DYES : Dyes are classified as Natural and Synthetic dyes. Dyeing and printing are finishing processes that provide lasting beauty and delight to the textile fabrics by adding colour. Dyeing and printing differs in the method by which colour is applied to the fabric. CLASSIFICATION OF DYES
