OBSERVATION

Question 4a i and ii was not answered very well, just few of the candidates did it well (what is scouring and singing); While the other questions in 4a was done well.

The expected answers are:


Scouring: It is the process of using hot soapy water to remove the natural grease and sweat from wool during the manufacturing of woollen fabric.

  1. Singeing: It is the process of using flame to burn off protruding ends of fibres after a fabric has been manufactured. 

  2. Printing: It is the process of adding colour and motifs to a fabric to make it attractive to consumers.
  3. Note: If candidate’s answer ends at ‘fabric’ deduct ½ mark.


  4. Knitting: It is the process of interlocking yarns into loops using special pins or machine.

4(b) Advantages of using polyester as curtain was done not too well by the candidates.

  • It drapes well.
  • It is strong and durable
  • It can be easily laundered.
  • It does not fade.
  • It does not crease.

 

4(c) Difference between felt and laminated fabrics was not answered very well
The expected answers are:
Felt fabric: It is a fabric made by fusing together fibres (usually woollen fibres) by using heat, pressure and moisture.


Laminated fabric: It is a fabric produced from at least two layers of material held together by heat fusion, adhesive, stitching or chemical tacking.
