Textile Dyes

Textile Dyes Organic molecules used in the dyeing and colouring of textile materials are called dyes. The permanent colouring of textile material is called dyeing, while the colouring substances themselves are called dyes. Professionals in the textile sector are researching the dyes used in the industry. For years, people have obtained various paints and dyes to colour objects and clothing around them. According to data obtained from historical studies, the first dyes used historically include indigo obtained from indigofera plants, alizarin obtained from rubia tinotoium, chrome yellow obtained from soil, schweinfurt green, turmeric and similar substances. By 1856, synthetic dye production had begun. Today, synthetic dyes are mostly used. However, natural dyes are still utilized in the colouring of handcrafted products such as carpets and kilims.

Advantages and Disadvantages of Natural Dyes

Natural dyes and synthetic dyes each have their own advantages and disadvantages. Looking at the advantages of natural dyes, first, some dyes in this category have quite high fastness values. However, some likewise have quite low fastness values. At the same time, natural dyes are considerably more economical. The fading levels of natural dyes are also generally such that they do not damage other colours and do not disturb colour harmony. Looking at the disadvantages of natural dyes, it is difficult to achieve all desired colours with these dyes. Especially in some rural areas, it is difficult to find plants that provide the desired colour. Furthermore, these plants need to be harvested during their flowering period and it is not always possible to obtain them. The colour range of natural dyes is also quite narrow, and the presence of tannins, cellulose and other substances from plants in the environment can damage the colour and complicate the process.

Advantages and Disadvantages of Synthetic Dyes

Regarding synthetic dyes, their richness in colour variety, bright colours, short dyeing process and constant availability are among their positive characteristics. At the same time, under the same conditions they can produce the same result and dye fibres more easily. Looking at the negative characteristics of synthetic dyes, fading occurs when working with those that have low fastness values, and these fadings disrupt colour harmony in other areas. At the same time, they are more expensive than natural dyes. The most important point to consider in textile dyes is suitability to the raw material to be applied. Not every dye is suitable for every raw material. For this reason, the areas of use of dyes vary according to their types. For example, pigment dyes are used in textile materials composed of synthetic fibres, particularly polyamide, polyester, cotton fibres and their blends. Regarding basic dyes, they are used in textile materials composed of cotton, viscose, modal and polyacrylonitrile fibres. Since compatibility between raw material and dye is an important matter, it is quite important to know which textile material each dye used is utilized in.
