What was the development of dyeing and weaving technology in ancient America?

The dyeing and weaving process in ancient America was extremely developed, which played an important role in the history of the development of dyeing and weaving process design in the world. Due to the dry natural environment in the desert area and the funeral custom of ancient Indians wrapping corpses with fabric, which is made of high-quality cotton yarn and alpaca hair and has good firmness, the fabric two thousand years ago is still as good as new. This kind of fabric can not only be used to make clothes and other daily necessities, but also play an important role in funerals, adult ceremonies, sacrifices and gifts. There was a great demand for this kind of fabric at that time. It takes 30 square meters of cotton cloth to wrap a mummy, and the custom there is that the best cloth must be given to the dead. The above social background has promoted the vigorous development of textile industry.
