History of yarn manufacturing draws our attention to the earliest days of the 19th century, when practically this was made possible by Ring Spinning. After this many developments have been made in terms of technology and improved process techniques have been adopted for the most efficient and convenient method of yarn manufacturing. So, what in fact the yarn is? "Yarn is a long continuous length of interlockedfibers, which may be used in various applications depending upon the intended end use.

There may be variety of yarns depending upon the manufacturing process for instance spun yarn, twist less yarn, fancy yarn, slub yarn, mélange yarn (Dyed yarn) and so on.

Indians were the pioneers in making the mélange yarn for the first time in 1980s. It may be defined as "the yarn produced by the combination of at least two or more than two fibers". Conventionally, the term mélange is used for such yarns which are produced by the combination of two fibers (whether of same type but different in color or type of fiber used is different). Further more, mélange yarn can be classified into two of its very basic types:

Blended Mélange Yarn: Such type of yarn in which different fibers are mixed/blended together in a certain fixed ratio for instance PC (Polyester Cotton blend) 50:50, PC 70:30, PV 80:20, CVC 40:60 etc.

Non-Blended Mélange Yarn: Yarn in which there are no different fibers blended together, but different colored fibers of same type are used to make the yarn e.g. 100% cotton dyed yarn, 100% bamboo yarn etc.
