Question 12

A clothing maker plans to make fleece jackets from used PET drinks bottles.

Why can the maker use the recovered bottles for this product?

[1]
A

Melted PET can be made into strong, flexible fibres, so it suits fleece clothing.

B

PET is a good conductor of heat, so fibres made from it keep the wearer warm.

C

Recycled PET is purer than new PET, so it suits clothing worn next to the skin.

D

Shredded PET flakes are already fibres, so they can be spun into yarn without melting.
