Step 2
Step 3
Sketch a care label suitable for a wool jumper.
Answer
When sketching a care label, include the following points:
-
Washing -
- Instructions: Machine wash on a gentle cycle with cold water.
- Explanation: This helps prevent shrinkage and maintain the shape of the wool.
-
Drying -
- Instructions: Lay flat to dry.
- Explanation: Hanging may cause the fabric to stretch.
-
Ironing -
- Instructions: Use a cool iron if necessary.
- Explanation: High heat can damage the wool fibres.
-
Bleaching -
- Instructions: Do not bleach.
- Explanation: Bleach can weaken wool and cause discoloration.
Step 4
Describe a fabric test that could be carried out in order to identify wool.
Answer
A useful fabric test to identify wool involves the 'burn test':
- Apparatus: Use a pair of tweezers, a non-flammable surface, and a lighter or matches.
- Method: Cut a small piece of the fabric and carefully hold it with tweezers. Ignite the fabric and observe its behavior:
- If it burns slowly and leaves a crispy residue, it is likely wool.
- The smell of burning hair is a strong indicator of wool as it is a protein-based fibre.
