Explanation: Wool traps air, a good insulator, which reduces loss of body heat.
Question 11 of 25
Most synthetic fibres are made from chemicals obtained from:
Cotton plants
Petroleum

Silk cocoons
Explanation: Synthetic fibres are manufactured from chemicals mostly derived from petroleum.
Question 12 of 25
A material made of many small units joined into long chains is called a:
Polymer
Mixture
Solution
Crystal
Explanation: Synthetic fibres are polymers — long chains of many joined units.
Question 13 of 25
Which synthetic fibre is stronger than a steel wire of the same thickness?
Acrylic
Nylon
Rayon
Cotton
Explanation: Nylon is exceptionally strong, stronger than steel wire of equal thickness.
Question 14 of 25
Polyester clothes need little ironing because polyester is:
Wrinkle-resistant
Heavy
Absorbent

Explanation: Synthetic fibres melt and can stick to the skin, unlike cotton, which burns to ash.
Question 20 of 25
Which property tells us how well a fibre soaks up sweat?
Strength
Cost

Heat resistance
Explanation: Moisture absorption describes how well a fibre soaks up water and sweat.
Question 21 of 25
A fabric made by mixing two or more different fibres is called a:

Wool
Silk
Cotton
Jute
Explanation: Terycot is a blend of polyester and cotton.
Question 23 of 25
Fibres are blended mainly to:

Make them weaker
Remove all colour
Explanation: Blending combines the desirable properties of each fibre while reducing weaknesses.
Question 24 of 25
Woollen clothes should be washed in:
