Do you know that there is a plant which has no surface tension thereby the water droplet are seen on its leaf by this natural phenomena scientists and people have made raincoats.
Shubhanshu said:

Materials used to make raincoats have high surface tension because due to surface tension water droplets do not stick to the material.

Normally the surface tension of the materials are seems to be higher.

Because drops of water falls with high surface tension therefore they are spherical.

What is surface tension?

Your explaining the obvious, don't you think you should be explaining more about why it is water proof? what it is in a surface tension that makes it water proof? just saying.

Because surface tension is the main cause for the nature of angle of contact.

The force is acted by inner material of raincoat, so by newton's third law of motion, tension force acts opposite to driving force, and this tension force is acted by surface so called surface tension. It opposes and overcomes the driving force and so water particles don't stick to material rather they sticks to surface and hence surface tension of raincoat materials are higher than their inner material.

What is Tension?

Tension is a type of force which balances the other acting forces.
