Dyeing And Bleaching Paper 2 WASSCE (SC), 2016

Question 1

What is tie-dye?
State three differences between batik and tie-dye.
mention seven printing tools and materials.

Observation

The question was popular among the candidates and their performance was above average. However, some candidates’ failed in stating appropriately, the differences between batik and tie-dye. This makes them lose substantial marks, they were expected to respond to the question thus:

(a)      It is a dyeing method in which resist agents such as strings/thread/rope/twine/raffia or any other tying materials are used to tie portions of the fabric to prevent absorption/penetration of dye solution in order to create/form paterns/designs.
     (b)

S/N	BATIK	TIE-DYE
1.	It permits the application of wax/starch on fabric as resist agent.	It involves the use of strings/thread/rope/twine/raffia or any other tying materials to tie specific areas of the fabric to prevent absorption/penetration of dye solution.
2.	It involves the processes of dewaxing.	It involves the processes of untying/removal of strings/thread/rope/twine/raffia from fabric.
3.	Cold water is more preferable for dyeing a batik fabric to avoid dewaxing in the solution.	Warm water is preferable in tie-dyeing production.
4.	Production requires longer time.	Production takes less time.
5.	Drawing of preliminary sketches is often required.	Drawing of sketches is less important.
6.	Fabrics are heavier after production.	Fabrics retain almost the original weight after production.
7.	More intricate lines can be achieved.	Less intricate lines can be achieved.
8.	More pronounced crackles are created.	Less crackles are created.
9.	Freehand sketching of design is required.	Freehand sketching of design is required.
10.	More ideal for wall hanging.	Less ideal for wall hanging.
11.	More skill is required.	Less skill is required.
12.	Multiple designs can be achieved.	It has limited designs in production.
13.	Production is more expensive.	Production is cheaper.
14.	Materials for production are scarcely available.	Materials for production are readily available.
