Dyeing is a method which imparts beauty to the textile by applying various colors and their shades on to a fabric. Dyeing can be done at any stage of the manufacturing of textile- fiber, yarn, fabric or a finished textile product including garments and apparels. The property of color fastness depends upon two factors- selection of proper dye according to the textile material to be dyed and selection of the method for dyeing the fiber, yarn or fabric. Dyes are used for coloring the fabrics. Dyes are molecules which absorb and reflect light at specific wavelengths to give human eyes the sense of color. There are two major types of dyes - natural and synthetic dyes.
The natural dyes are extracted from natural substances such as plants, animals, or minerals. Synthetic dyes are made in a laboratory. Chemicals are synthesized for making synthetic dyes. Some of the synthetic dyes contain metals too. And the solution pigmenting or dope dyeing is a kind of dye added to the solution before it is extruded through the spinnerets for making synthetic filaments. Dope dyed yarn is a synthetic yarn where the polymer, before the extrusion process, is mixed with dye and extruded fibers are then colored. This gives a yarn with excellent color fastness and light fastness characteristics.important to buy the equipment suitable for your business.
