Name of the Experiment: – Dyeing Jute yarn with Basic dye.
Introduction:
It is suitable for acrylic fibers (other fibers by mordanting). It reacts with acetic groups, or mordants a chemical which can react or complex with a chromophore to form an insoluble color in the fibre. It has good fastness properties on acrylic fibres.
Objects: The main object of this process is to dye yarn.
- To dye jute yarn.
- To know about Basic dyestuff.
- To know how it work.
- To have an idea of dyeing curve on jute yarn.
- To know about the recipe.
Recipe:
- Dyestuff = 1% owf.
- Acetic acid = 1 gm/l
- Sodium Acetate =2gm/l
- Temperature = 90° c-95ºc
- Time = 45 min
- M :L = 1: 20
Calculation: –
- Sample weight = 5 gm
- Here we shall prepare stock soln
- Acetic acid = (1×100)/(1000×1%) =10cc
- Sodium Acetate=(2×100)/ (1000×1%) =20cc
- Additional water require =100- (10+20+5) = 65 cc
Procedure : –
First required amount of dyestuff ,acetic acid agent is mixed in a closed vessel. Then additional water & Sodium Acetate are added to this mixture. Finally sample is taken in this soln and closed the open end of the vessel. Then vessel is kept on the rotadryer m/c and heated 90° c for 1 hour.
Then the vessel is open and the sample is drawn out and washed with water.
Precaution: –
- The sample should be kept uniformly in the mixture. Otherwise non-uniform dyeing will do.
- Amount of chemical and water must be accurate.
- Chemical must mix with water very well.
Conclusion: –
Dyeing is an important experiment in textile technology. Jute is the mostly used fibre from old ages to now. So, this experiment will do a great favor to us in future days.
