- Wool — comes from sheep, goats, yak, rabbits (angora), camel. Keeps you warm in winter.
- Silk — from silkworm cocoons. Smooth, lustrous, strong.
Animal fibres are made of protein (keratin in wool, fibroin in silk).
Wool traps tiny air pockets → insulates against cold. Silk thread is super thin yet strong.
Example
Kashmiri pashmina shawls come from a special mountain goat's fine underfur. A single silk cocoon yields about 1 km of thread!
💡 Tip:Wool burns with a hair-like smell (protein). Cotton smells like paper (plant matter).
