Denim Fabric Evolution and History of Washing
More than 500 years ago, Italian navigator Columbus discovered the New World. The sails for the sailing ships at that time were made of a very tough and practical rough cloth. This coarse cloth originated in a French town of NIMES, so it was named "Serge De Nimes" in French and was later referred to as "DENIM".
After 306 years, a Jewish businessman in the United States, Levi Strausss, introduced a rough canvas into the United States, creating a historic page for jeans and establishing a mythical kingdom of cowboy culture.
The mythical kingdom of Levi'S cowboys began in San Francisco, United States. The rough canvas originally used to make tents produced the first LeviS jeans for the miners at the time. It was a tough and durable workwear because it suits the needs of workers. Quickly welcomed, which led to a series of evolution. Jeans were primarily brown, and they were later changed to denim, a denim fabric that became familiar to people.
