when silk or wool are burnt, thy smell like burning hair However when cotton is burnt, it smells like burning paper Why
Paper is made out of plants. Cotton is also made out of plants. So they both give out similar fumes while burning as their origin comes from plants. Wool is made out of sheep and silk is made out of silk worms. They create hair like fibers which are woven to form silk.. fabric. That's why they give hair burning smell.
