More than 500 years ago, the Italian navigator Columbus discovered the New World. The sails used for sailing ships at that time were made of a very tough and practical rough cloth. This rough fabric was originally produced in a small town in France, NIMES, so it was named "Serge De Nimes" in French and then referred to as DENIM.
And three hundred and sixty years later, a Jewish businessman in the United States, Levi Strauss, introduced a rough woven canvas into the United States, thus creating a historic page of jeans and establishing a mythical kingdom of cowboy culture.
The myth kingdom of Levi's cowboys began in San Francisco, USA, and made the first LeviS jeans for the miners who used to make tents. It was a tough and durable overall, because it fits the needs of the workers. It was quickly welcomed, which led to a series of evolutions. Jeans were originally made in brown, and later changed to dark blue twill denim.
Denim is mainly made of cotton. It also develops a variety of raw material structures. It is blended with cotton, wool, silk and hemp natural fibers. It is also blended with chemical fiber, and uses elastic yarn, tight crepe, fancy yarn and other raw materials. The higher the content of spandex, the greater the elasticity. Yarn support has 7*7, 7*6, 7*8, 10*7 and other specifications. The structure is generally twill (2/1, 3/1, 1/3), broken twill, and the radial tightness is greater than Latitude.
The color of denim has evolved from vulcanization and indigo to light blue, black, white, and color.
There are many processes for finishing denim, which is an important part of the development of denim series. Among them are: enzymes, stone grinding, sandblasting, cat whiskers, silicone oil, bleaching, coloring, snow washing.
