Dyes refer to colored organic compounds that can obtain color from fiber materials, but not all colored organic compounds can be used as dyes. Dyes are key substances that give colors to materials and processes, and are widely used in textiles, printing, leather, food and other fields. As dyes, there are generally four elements. In order to better understand and apply dyes, it is crucial to master the four major elements of dyes—Chroma
Dyes refer to colored organic compounds that can obtain color from fiber materials, but not all colored organic compounds can be used as dyes. Dyes are key substances that give colors to materials and processes, and are widely used in textiles, printing, leather, food and other fields. As dyes, there are generally four elements. In order to better understand and apply dyes, it is crucial to master the four major elements of dyes—Chroma,Ability to Color,Solubility and Color Fastness.
The dye must be able to produce a certain concentration of color (with a certain dyeing improvement rate)
Dyes have a certain binding force with textile materials, that is, affinity or directness.
Commonly known as dye strength, it is a comprehensive indicator of the coloring ability of commercial dyes.
Dyes can be dissolved directly in water or chemically dissolved in water.
Dyes are able to penetrate into fibers or matrices at a molecular level and interact with them to form chemical bonds.
The colors dyed by dyes on textile materials need to be durable and not easy to fade or change color.
During their use, textiles are subject to various external effects such as light, washing, ironing, sweat stains, friction, and chemicals. Some printed and dyed textiles also undergo special finishing processes, such as resin finishing, flame retardant finishing, sand washing, and grinding. Wool, etc., which requires the color and luster of printed and dyed textiles to maintain a certain degree of fastness.
In practical applications, these four elements influence and interact with each other. In order to achieve the best dyeing results, these four aspects must be considered comprehensively. For example, when selecting a dye, you must not only consider its color and light characteristics, but also combine the properties of the material and the expected use environment, select appropriate additives and processes, and adjust the concentration to achieve the ideal dyeing effect.
