Answer 2

Smart materials have properties which change in response to external stimuli.

Question 3

Describe photochromic textiles and suggest possibles uses.

This could be used for beachwear which responds to prolonged sun exposure.

Question 4

Describe phosphorescent dye and suggest possibles uses.

Answer 4

Phosphorescent dye causes fibres to glow in the dark.

This could be used for Halloween costumes or to make cyclists more visible at night.

Question 5

Describe microencapsulated textiles and suggest possibles uses.

Answer 5

This could be used for scented bedding, antibacterial fabrics, or mosquito repellent fabrics.

Question 6

Describe D30 and suggest possibles uses.

Answer 6

Answer 7

1. Thermochromic textiles.
2. Photochromic textiles.
3. Phosphorescent dyed textiles.
4. Microencapsulated textiles.
5. D30.
