List the advantages and disadvantages of synthetic fibres.

Advantages:

Most synthetic fibres do not absorb much moisture and do not allow for air circulation, making them hot and uncomfortable to wear.
Synthetic fibres such as polyester are not heat resistant and catch fire easily.
These fibres are strong and elastic, giving them bounce properties.
They don't wrinkle easily, and their colour and brightness last much longer than natural fibres like cotton.
Synthetic fibres are manufactured from petrochemicals and have a long shelf life in the environment. It degrades into microscopic particles known as microplastics, which pollute land and water bodies such as rivers, lakes, and oceans.
Using synthetic fibres such as nylon is stronger than many natural fibres such as silk or wool.
