CREATE DESIGN WITH BLOCK PRINTING – VEGETABLE / WOODEN BLOCKS (Lab Manual)



Aim:

To print the given cotton material using Wooden / Vegetable blocks with the required portion of fabrics (All over design and Border design).

Recipe:

  • Dyes = 4gm

  • Urea = 10gm

  • Thickener = 50gm

  • Resist salt=1gm

  • Soda ash=6gm

  • Additional water = as required.


Preparation of thickener:

  • 16 gm of starch and 200cc water are taken in bowl.

  • Heat is applied and solution is stirred continuously until a thick viscose solution is obtained.

  • By continuous stirring and boiling a specific viscosity is obtained.

  • The heat application is stopped otherwise viscosity falls down. So temperature is maintained strictly.

Preparation of printing paste:

  1. At first we take required amount of dyestuffs in a bath.

  2. Then little amount of water is added into the bath for mixing these dyes. And start stirring for mixing the three types of dye.

  3. Then required amount of urea is added into the dye bath.

  6. After mixing finally required amount of alkali is added to the dye bath and mix them with the help of stirring.


Printing process:

Block printing method:

  1. The fabric which will be printed is placed on the printing table.

  2. The printing paste is put on the tray box.

  3. The block is selected and it is touched with print paste.

  4. The fabric which will be printed is placed on the printing table.

  5. The printing paste is put on the tray box.

  6. The block is selected and it is touched with print paste.

Result:

The given cotton sample material was printed by using Wooden / Vegetable blocks with the required portion of fabrics (All over design and Border design).
