As a way of fascinated yarn production, there were many attempts for the air-jet spinning innovations such as “Dupont” in 1956, “Rotofil” in 1971, “Toyada” in 1983, “Toray” in 1985, etc. But these methods had little commercial success. A renaissance in the historical development of air-jet spinning started with the MJS machine of the Japanese company Murata Machinery Ltd (Murata Jet Spinner). The company introduced its first air-jet spinning machine, Murata Jet Spinner, MJS 801, at the American Textile Machinery Exhibition in 1982 (ATME ’82). The machine contains a three-roll drafting system and is equipped with two air-jet nozzles that create air vortices rotating in opposite directions. In this system, the second nozzle creates false twist on the fiber bundle coming out of front roller. There is an air vortex between the front roller and the first nozzle which removes the twist and causes the edge fibers to be separated from the fiber bundle. So the edge fibers move to second nozzle in an untwisted form. However, the core fibers are directed to second nozzle in a twisted form. At the time of the second nozzle leaving, the core fibers are unwrapped and the edge fibers are twisted in the opposite direction. The system is stated to be suitable for processing man-made fibers and their blends with cotton; however, it was not capable of spinning 100% cotton or rich blends of cotton yarn [3]. Figure 1 displays the MJS yarn formation and the yarn structure in a detailed form.
