Alfa Chemistry Supplies Varieties of Dyes for Industrial Use

November 24, 2020

Dyes are indispensable in our daily life because they are widely applied in manufacturing like paper, leather, fur, hair, drugs, cosmetics, waxes, greases, plastics and textile. In response to the growing demand for dyes, Alfa Chemistry, a New York-based chemical supplier, announced to offer rich choices of dyes that can be used in various industrial scenarios.   A dye is a colored substance that chemically bonds to the substrate to which it is being applied. Compared with dyes, pigments do not chemically bind to the material they color. Dyeing is believed to have originated in Neolithic times, about 4000 to 9000 years ago. Dyes are usually soluble in water. There are natural dyes and synthetic dyes. Most natural dyes have plant origin and can be extracted from roots, berries, bark, leaves, wood, fungi and lichens. However, most synthetic dyes are made synthetically from petrochemicals.   Alfa Chemistry provides many types of dyes, including acid dyes, azoic dyes, basic dyes, cationic dyes, coupler, direct dyes, disperse dyes, neutral dyes, pigments, reactive dyes, solvent dyes, sulfur dyes, vat dyes.   Application of different dyes   Acid Dyes Often used in the dyeing of fibers such as silk, wool, nylon, and modified acrylic fibers, and use neutral to acidic dye baths.   Basic Dyes Mainly used for the dyeing of acrylic fibers, wool and silk as well as paper coloring.   Disperse Dyes Commonly used to dye polyester, but they can also be used to dye nylon, cellulose triacetate and acrylic fibers.   Reactive Dye Regarded as the best choice for dyeing cotton and other cellulosic fibers in homes or art studios.   Sulfur Dyes A cheap choice to dye cotton with dark color.   To learn more about Alfa Chemistry’s varieties of dyes or if you have any questions about the application of dyes, please visit or just email at for suggestions.   About Alfa Chemistry It is always Alfa Chemistry’s goal to become a reliable partner for universities, research institutes as well as manufacturing companies, supplying a comprehensive range of chemicals like building blocks, reagents, catalysts and reference materials.
