Denim has a global presence, it not only exists in every country in the world, but in many of these it has become the single most common form of every day attire. It has now become a symbol of modeling and modern culture. Denim is a strong, durable fabric constructed in twill weave. Denims can be classified into several categories according to their dyeing, composition, spinning, finishing and embellishment used. Denim industry like any other textile and clothing products is largely fragmented. While the westerners were the major producers of denim in yesteryears, now Asian manufactures are contributing to about 50% of the world denim capacity. Most of the production in Asia is generated primarily in China and India. Now a day’s denim comes in all forms, looks and washes to match with every dress. It would be difficult to believe that the same denim was originally worn by miners on the west coast but in present it is found in everyone’s wardrobe.
