The Making of Jeans Jeans are trousers made from denim or dungaree cloth. It is very popular casual wear around the world. Firstly, jeans are made with two styles, indigo blue and brown cotton duck. However, the brown cotton duck material is too uncomfortable to be worn so it has been out of the market. Denim pants had been around as work wear for many years since 1600s in England. The fabric that called denim was the first use of rivets that created what we now call jeans. The traditional name of jeans is “waist overalls” which means “pants for work”. The word “ jeans” became more popular around 1960 when the baby-boom generation take it as their favorite pants. Blue jeans are made of 100 percent cotton, that includes the threads. Polyester blends are less popular compared to cotton made one . To make a jeans, demin was treated with a blue dye obtained from the indigo plant which had been used as a dye since 2500 B.C. in such diverse places as Asia, Egypt, Greece, Rome, Britain, and Peru. Blue jean manufacturers imported indigo from India until the 20th century, when synthetic indigo was developed to replace the natural dye.
