Explanation:

answer 1

chracterstics of synthetic fibres

1 synthetic fibres are cheaper than natural fibres

2 synthetic fibres are stronger than natural fibres

3 they are more durable than natural fibres

4 synthetic fibres dry in less time

5 synthetic fibre are easy to use and wash

answer 2

thermosetting plastics

they cannot be bent easily and do not soften upon hearing

they used for making objects that may get hot on use

examples bakelite, resin

thermoplastics

they can be bent easily and soften upon heating

they are used in making objects that do not get too hot

example polythene , pvs

Answer 2

Characteristics of Synthetic Fibres:

• Synthetic fibres are cheaper than natural fibre.
• Synthetic fibres are stronger than natural fibre.
• Synthetic fibres are more durable than natural fibre.
• Synthetic fabrics are dried up in less time.
• Synthetic fibres are easy to maintain and wash.

Difference between Thermoplastic and Thermosetting plastic:

The primary difference between the two is that Thermoset is a material that strengthens when heated, but cannot be remolded or heated after the initial forming, while thermoplastics can be reheated, remolded, and cooled as necessary without causing any chemical changes.
