Types of Dyes are Used for Different Textile Fibers
Fabrics look attractive due to vivid colors. We can’t imagine them without it. Dying process makes the yarns, fibers and fabrics colorful by using either synthetic or natural dyes.
With time, the methods have evolved tremendously, and we have more sophisticated and automated ways to accomplish the task.
In the textile making process, dyes can be introduced at several levels:
- Prepared fabric
- Finished goods
Fastness and color quality depends on many aspects:
- Selection of proper dye
- Choice of the dying method
Types of dyes
In the broader sense, any material that adds color to the textile is called dye. The color is incorporated into the fibers by absorption, dispersion or chemical reactions sometimes.
Dyes differ in several aspects from each other:
- Resistance to sunlight
- Gas, alkalis and other agents
- Reaction to cleaning or bleaching agents
The method of application also affects its durability and fixation. Some examples of dyes and their uses are:
These dyes are ideal for animal fibers like wool. They are not used in cotton or linen usually. If required, then mordant is used in the process. Fixatives are necessary to increase fastness.
They are made from natural ingredients. The direct printing approach is used for dying the stuff. When it is done on colored fabric, it is called overprinting.
Thickening agent (preferably starch) is used in a limited quantity of water, and dye is dissolved. Some other agents are gums and alginates.
Basic dyes are ideal for acrylic fibers. The use of mordant is mandatory while using basic dyes. It is nothing but a chemical agent that forms an insoluble compound with the dye.
Basic dyes are used for in dying cotton, linen, nylon, polyesters and modacrylics with mordant in a small percentage. They aren’t fast to light, perspiration or washing on other fabrics, though.
Basic dyes are used for giving the ‘after treatment’ to the fabrics that have already been dyed using acid dyes.
Synthetic dyes are classified into several categories based on the method of application and chemical composition.
- Direct dyes: They are used for dying silk, wool, nylon, and rayon.
- Sulfur dyes: Ideal for cotton and linen as the colors are fast.
- Disperse dyes: Can be used for dyeing acrylic and nylon.
The pigments are used for coloring wool and cotton due to the excellent lightfastness. Resins are used for fixing pigments on the fabrics.
Many other dyes are also there used in the fabric industry based on requirement.
