Brief overview of dyes and pigments

Color plays a key role in influencing our feelings, responses and actions towards people, things, and ideas.

Today's color is derived from pigments containing pigments and dyes. From ancient times, dyes have been used for dyeing, but at that time they were obtained from nature. Detection of coloring products made of coal tar and petroleum distillation resulted in a change of coloring. A wide range of dyes and dyes were available on the market, each of which had their own applications.

Coloring and coloring differ from each other, with a large difference in the water solubility of colorants, unlike its analogue, coloring. Coloring tends to the substrate and may be absorbed or chemically reacted with the substrate. There are several factors that determine the category of color, such as chemical structure, origin, nuclear structure, application methods and industry classification. One example of pigment and the corresponding substrate that can be given here is a direct pigment and its substrates are cellulose, cotton and blends. The staining methods today have also increased widely, including batik dyeing, bale dyeing, beam dyeing, chain dyeing and speck dyeing etc. Although pigments are used in varied applications today, a large part of it goes into the textile industry in the country while the remainder is used by the paper and leather industry.

Coloring agents against dyes are oil and water insoluble. Coloring is responsible for lending on several items; although her biggest consumer is the paint, printing ink and coating industry. The classification of pigments is based on their chemical composition, color, source and use. Based on chemical composition, pigments are divided into organic pigments and inorganic dyes. Coloring is divided into natural and synthetic based on their purchases. In addition to these classes, pigments are also classified in magnifying glasses, dyes and functional dyes after their use.

In the case of organic pigments, there are many of them, but many of them are barely used today or rarely used. Organic pigment manufacturers would list Phthalocyanine pigments, azo pigments, quinacridone dyes and water dyes as the most common ones in their class. These categories provide countless tones and colors for various applications of each category that contribute to different colors. Pigment Blue producers are therefore more concerned about producing Pthalocyanine classification of pigments that give green and blue tones.

Concepts of dyes and dyes are often used loosely to refer to colors seen in fabrics, food, paints, etc. but each of them differs from each other. In any case, the fact is that they both make the day the world much more colorful!
