The use of this dye is dangerous. this is because they contain toxic chemicals, so they should be used with extreme caution. the article on safety precautions are mentioned at the end, so be sure to read it before use
There are 3 main ingredients used for waxing,
Beeswax Paraffin Wax Rosin
These 3 ingredients to a specific ratio and melt well, and mix. After preparing in this way, use it to wax the silk cloth.
(If the beeswax is 25g-50g, take about 1Kg of paraffin wax and 20g of powdered rosins)
This method is not suitable for cotton fabrics.
Required materials
- Naphthol (ASSG, ASSW, ASG, ASBO)
- diazonium salt color(Red B, Geen BB or any other)
- Wine spirit (IPA)
- Caustic soda
- Hydrochemical
- Hot water
- Some pots
- A spoon
How to make
- Put the required amount of naphthol pigment in a basin. (About 50g of dye per yard of silk)
- Add about 20ml of Wine spirit and mix well with the pigment to make the dye easier to dissolve.
- Add about 20g-25g of the hydrochemical to the prepared mixture and mix again. (This Chemical packet can be kept for a maximum of 3days after opening because it can react with air)
- Then add some hot water to this naphthol mixture.
- Now take another bowl and add about 50g of caustic soda to it and mix it with normal water. (not cold or hot water)- Wear gloves when handling this.
- Then add this caustic soda mixture to the pre-prepared naphthol solution. ( Then the color of the solution changes)
- Now put regular water in a slightly larger container and add the finally prepared naphthol solution to it. ( This container will use for dyeing)
- Now put the waxed batik design into a naphthol dye solution, and soak for about 10 minutes.
- In the meantime, add the color (Red b or any) we want to dissolve with some regular water. (This pigment should be applied at about 100g per 1m of Silk fabric)
- After 10 minutes, remove the design from the naphthol solution. Then you can see that the color of the fabric has changed. If the color doesn’t vary, the naphthol is not applied correctly to the material.
- Remove the design from the solution and leave for a few minutes for the water to drain.
- Now put the design to the color(Red b or any other) solution to be prepared later.
