What is hide in leather?
Hide (Extracting a particular portion from the skin)
Hide in leather is the portion extracted from an animal. The hide varies from animal to animal depending on the surrounding, environment, and climate change.
If the animal is living in cold areas it will have thick fur and the skin is protected well. Whereas in hot areas the animals may have less hair making them vulnerable to the environment.
Different animals produce different kinds of leather based on the above mentioned factors. Later on, the part of the skin is moved to grade process.
