Dyeing And Bleaching Paper 2 WASSCE (SC), 2016

Question 6

 

(a) Define the term plain dyeing.

(b) List five techniques of tying a fabric.

(c) Arrange sequentially, eight steps to achieve crackles in a waxed fabric decoration.

Observation

 Candidates’ performance was above average in this question. This might be as a result of the popularity of the question with the candidates. However, some candidates failed to arrange sequentially the steps to achieve crackles in a waxed fabric decoration. This made them to lose some marks. They were expected to respond to the question in the following manner:

 

(a) Plain dyeing is a process of decorating fabrics into a monochromatic/one colour scheme in a dye bath/ solution.

 

(b) - Folding;

- Marbling/Squeezing/Crumpling;

- Pleating;

- Splashing;

- Twisting/Spiral;

- Knotting/Tied circles;

- Clamping;

- Clump tying;

- Stitching/Sewing;

- Spraying;

- Bunching;

- Concentric squares;

- Concentric circles;

- Bolting/Sandwiching/Criss-crossing.

 

(c) - Get all materials ready such as fabric, wax, dyes, chemicals, bowls, etc.

- Plan and transfer the design on fabric.

- Melt the wax to normal temperature.

- Apply the melted wax on the fabric.

- Prepare cold dye bath/ solution.

- Squeeze/fold/twist the waxed fabric to achieve crackles.

- Dip the waxed fabric into the cold dye bath/ solution and leave for a while.

- Remove the fabric to oxidize.

- Dewax the dyed fabric.

- Rinse and dry under shade.

- Iron the fabric.

- Package the fabric.
