Product Description

Reactive dyes are a grade of very shaded natural substances, basically utilized for tinting fabrics, that join themselves to their substances by a synthetic reaction that structures a covalent binding between the atom of color and the fiber. The color stuff subsequently turns into a part of the filament and is substantially less liable to be expelled by washing than are color stuffs that follow by assimilation.

The primary fiber receptive colors were intended for cellulose strands, and they are utilized for the most part along these lines. There are likewise economically accessible fiber reactive colors for polyamide and protein fibers. In principle, fiber reactive colors have been produced for different fibers, however the colors are not yet down to earth industrially. The colors include a reactive class that, when used to a filament in a feebly antacid color shower, frame a compound blend with the fiber. Further, reactive colors can additionally be utilized to color fleece and nylon, in the last case they are used under feebly acidic situations.

The most critical property of reactive colors is the generation of covalent ions with the substance to be shaded, i.e. the color structures a synthetic ion with cellulose that is the primary part of cotton strands.

Our colors are the most changeless of all color sorts. Dissimilar to different colors, it really frames a covalent ion with the protein or cellulose atom. Once the association is framed, what customers have is one particle, as the color atom has turned into a real part of the cellulose fiber particle. No big surprise customers can securely wash a fabric, which has been colored in splendid fiber reactive hues with white apparel, a hundred circumstances, without jeopardizing the whites at all - regardless of the possibility that it is all extraordinary brilliant hues, or even strong dark! Rather than every other color the reactive colors tie artificially to the fabrics fibers, altogether enhancing the item's shading balance and launderability. Along these lines responsive reactive coloring of cotton is as of now the most far reaching coloring procedure on the planet.

Reactive colors are the most widely recognized and tremendous usages colors everywhere throughout the world. The vast majority of the coloring working of inherent fiber is performed by reactive colors. These colors possess an overall acknowledgment to the coloring technologist for coloring cotton. Our colors are just class of colors that makes covalent connection with the filament and turns into a piece of it. This can be portrayed as:

Grouping of Reactive Dyes:

By relying upon synthetic composition reactive colors can be named:

  • Chlorotriazine Dyes (MCT)
  • Heterocyclic Helogen Containing Dyes (HHC)
  • Vinyl Sulphone Dyes (VS)
  • Mixed Dyes (MCT-VS)

By relying upon utilization techniques for temperature, reactive colors can be delegated:

1. Frosty brand reactive colors: This kind of reactive colors is used in low temperature that varies between 25-50 degree Celsius. They are exceedingly responsive with various sorts of fibers at this temperature. .

2. Medium brand reactive colors: This sort of colors is utilized in a median temperature differs from 40 – 60 degree Celsius.

3. Low brand reactive colors: This sort of colors possesses less reactivity features with fiber in examination with high and medium brand reactive colors. Coloring is completed on temperature that ranges from 60 to 90 degree Celsius.

Characteristics of reactive dyes:

  • Reactive color is water dissolvable, anionic in nature

  • It has much better light and wash fastness as well as substantivity

  • Alkaline state should be required for coloring

  • Electrolyte is should for exhaustion of colors in the fiber

  • A specific measure of colors are hydrolyzed amid application

  • Extensive variety of shading can be delivered with reactive colors

  • Similarly shabby in cost.
