|Reactive Bi-Functional Series
The increase in dyeing cotton fabric and has excellent water solubility. This method is useful for dyeing fatigue. With two active and is suitable for continuous dyeing. It is characterized by excellent performance in all applications. According to the needs of our customers can benefit variations in color.
Reactive dyes are a class of organic materials very colorful , primarily used for coloring fabrics , which attach themselves to substrates via a chemical reaction to form a covalent bond between the molecule of dye and fiber . Dyestuff thus becomes a part of the fiber and less likely to be removed by washing of the dyes that are committed by the adsorption of so much.
Reactive dyes are more durable fibers for all types of dye. Unlike other dyes , which actually forms a covalent bond with cellulose or protein molecule. Once formed the union , what you have is a single molecule, as the dye molecule has become part of the molecule cellulose fibers themselves . No wonder you can safely wash your dress has been dyed in bright fiber reactive colors with white clothes , a hundred times , without compromising the eggs at all - even if it's all the bright colors , or even solid black ! In contrast to all other dyes reactive dyes chemically bond to textile fibers and significantly improve the color stability of the product and the washing capacity . The reaction die cotton therefore the process is currently most prevalent tissue death in the world.
