1. Action of water:
Natural fibres absorb water quite efficiently whereas synthetic fibres do not. Other synthetic polymers also do not absorb water. You have already learnt that clothes made of fabrics that absorb water are more comfortable to wear than clothes made of materials that do not
2 Action of heat and flame:
Most synthetic polymers are heat sensitive. On being heated, they melt, and at higher temperatures they burn.
Vegetable fibres are heat resistant—they do not melt. Nor do they catch fire as easily. Animal fibres are heat sensitive.
