It is called thermosetting plastic because it doesn't change it's shape when heated.
Some more examples of thermosetting plastics are :
- melamine
- silicon
- epoxy
2.Cellulose
A number of glucose units make up the polymer cellulose.
3.Non biodegradable
Synthetic fibres are non biodegradable that is cannot be decomposed by bacteria and hence cause soil pollution
4.All of these
Synthetic fibre show properties of being flammable, wrinkle free,easy dry ,etc.
