Answer: (a) They have a uniform structure as they are man-made.

After scouring, wool fibres are often treated with grease extraction. Why is grease removed, and where is it commonly used?

1. Grease is removed to make wool softer, and is used in food processing.
2. Grease is removed to prevent fibre stickiness, and is used in skincare and lubricants.
3. Grease is removed to lighten the colour, and is used in making synthetic fibres.
4. Grease is removed to increase wool's elasticity, and is commonly used in paper production.

Answer: (b) Grease is removed to prevent fibre stickiness, and is used in skincare and lubricants.

A clothing company wants to manufacture woollen garments that are soft, warm, and resistant to shrinkage. However, during processing, they notice that some wool fibres have natural kinks and curls, making them difficult to blend evenly. Which technique should be applied to improve the fibre quality before spinning?

1. Blending with synthetic fibres to straighten out the wool strands
2. Combing and carding to separate short and long fibres and align them
3. Scouring with stronger detergents to remove the natural kinks in wool
4. Direct spinning without processing to retain the natural structure

Answer: (b) Combing and carding to separate short and long fibres and align them
