Helo, reders welcome to “textile green”  today i m going to explain about reactive dyeing recipe. I m writing all information in this article with my personal view. so please read complete my article. In case of reactive dyeing, I m going to explain about reactive dyeing recipe.

Reactive Dyeing Recipe For Cotton materials

First of all I m going to explain about chemical which is used in reactive dyeing and reactive dyeing process also. No of chemicals are used in reactive dyeing and now I m going to explain about important chemicals. what is main functions of  chemicals which is used in reactive dyeing.
Here, I m going to explain about all chemicals which is used in reactive dyeing.

1. Wetting agent
2. Seqestering agent
3. Anti foaming agent
4. Dyes
5. Glauber salt
6. Soda ash
7. Lubricating agent
8. Temperature
9. Time
10. PH
1. Wetting agent       –    0.2  to  0.5  g/l
Fuction of wetting agent in reactive dyeing.
(a) Reduce the surface tension of outer fabric surface.
(b) increase the water absorbancy of fabric.
(c) many wetting agent are also work as a scouring agent.
2. Seqestering agent  –     1.0  to  2.0  g/l
Fuction of seqestering agent in reactive dyeing.
(a) Reduce the hardness of water approx 2 ppm which is able to reactive dyeing.
(b) seqestering agent also help in diffusion of dye in water.
3. Anti  foaming agent   –    0.5  to  1.0  g/l
(a)  the main function of foaming agent is it’s help in Reduce the foaming in water during dyeing.

4.  Dyes       -.             X% (as needed)

5. Glauber salt   –         Yg/l ( it’s based on depth of shad and for depper shad more salt is required)
(a) it is also known as exhausting agent. the main function of Glauber salt is exhaust the dye liquor in fabric surface.
6. Soda ash       –       Zg/l  (based on depth of shad)
 (a)the main function of soda ash is increase the alkalinity in dye bath.

(b) it help the maintain PH balance of the water.

(c) it also help  the dye bond to the fabric.

7. Lubricating agent     –       1.0  to  2.0 g/l

(a) Reduce the heat generated when surface move.

(b) Reduce the friction between surface in mutual contact.

(c) transmitting the force

(d) Reduce the heat and cooling the surface.

8. Temperature   –           50°C to 55°C

Reactive dyeing is done in room temperature

50°C to 55°C

9. Time.            30  –  60  minutes

in case of dyeing, fibre by absorption, diffusion or bonding time with temperature and time being key controlling factors.

10. PH              -.       10.5   to  0.5

(a) Controlling PH is very important in dye bath because it’s effect on the dyeing cycle.

(b) it is greatly influences the uptake of dye.

11.  MLR              –       1:5  to  1:0

It is the ratio of weight of the treatment solution in (liters) divided by the weight of the fibre in kg.

Thank you
