Experiment Name :

Scouring and bleaching of 100% cotton knitted fabric of single stage.

Theory :
In this experiment scouring and bleaching is done together.Scouring is done to remove fats and oils from textile materials.By doing this process textile materials become more absorbable then before.Bleaching is done to remove natural colour.By doing this process textile materials become luster and white then before.So after finishing this process textile materials are ready for dyeing besides bleaching process impart and permanent whiteness of textile materials. 

Nature of sample :
The sample that we have taken a cotton fabric.It is carded yarn's fabric and knitted fabric.

Instruments required : 
1. Gas burner
2.water
3.Thermometer
4.Glass rod
5. Scissor etc.

Process sequence : 
Grey fabric - Scouring and bleaching(25 min) - Cold wash - Hot wash - Cold wash - Drawing .


Recipe : 
Drtergent = 1 g/L (stock solution- 1%)
NaoH = 2 g/L ( stock solution- 2%)
H2O2 = 4 g/L (stock solution- 2%)
Stabilizer = 1 g/L (stock solution- 1%)
Temperature = 100' C
Time = 25 min
Sample wt = 5 gm
M:L = 1:40


Calculation :
Sample wt = 5 gm
M:L = 1:40
Amount of total liquor = 5 X 40 ml = 200 ml
Detergent = (200 X 1) / (1000 X 1%) = (200 X 1 X 100) / (1000 X 1) = 20 ml 
NaoH = (200 X 2) / (1000 X 2%) = (200 X 2 X 100) / (1000 X 2) = 20 ml
H2O2 = (200 X 4) / (1000 X 2%) = (200 X 4 X 100) / (1000 X 2) = 40ml
Stabilizer = (200 X 1) / (1000 X 1%) = (200 X 1 X 100) / (1000 X   1) = 20 ml
Total water = 200 ml - (20 + 20 + 40 +20) ml = 100 ml


Procedure : 
First we have to take total liquor in a glass. In the glass we have to take the sample. After taking all these we have to heat the glass in 25 min. In heating process we have to shake total liquor by glass rod in time to time.

Conclusion : 
Scouring and bleaching is very important in textile industries for many purposes. In this experiment we came to know how to do bleaching and scouring. We think, this experiment will be very helpful in our future working life.

Salt = 2 g/L (stock solution- 1%)
Temperature = 100' C
Time = 20 min
Sample wt = 5 gm
pH=7-8.5
M:L = 1:40


Calculation :
Sample wt = 5 gm
M:L = 1:40
Amount of total liquor = 5 X 40 ml = 200 ml
Direct dye = (5 X 1%) / 1%  = 5 ml 
Wetting agent = (200 X 1) / (1000 X 1%) = (200 X 1 X 100) / (1000 X 1) = 20 ml
Salt = (200 X 2) / (1000 X 1%) = (200 X 2 X 100) / (1000 X 1) = 40 ml
Total water = 200 ml - (5 + 20 + 40) ml = 135 ml


Procedure : 
First we have to take total liquor in a glass. In the glass we have to take the sample. After taking all these we have to heat the glass in 20 min. In heating process we have to shake total liquor by glass rod in time to time.After finishing this process we have found a color fabric.
