What is the material from lobsters and crabs that can be made into cloth.?

The material from lobsters and crabs that can be made into cloth is called chitin, which is a natural polymer found in the exoskeletons of these crustaceans. Chitin can be processed to create chitosan, a biodegradable substance that can be spun into fibers and used to make textiles. This innovative use of marine byproducts contributes to sustainable fashion alternatives.
