Abstract: At present, ring spinning, compact spinning, rotor spinning and air-jet spinning are the four main types of spinning menthods. By comparing the principle of the four spinning methods, the corresponding yarn and fabric, this paper analyzed air-jet yarn’s characteristics, and summarized its advantages in appearance evenness, pilling resistance, water absorption, resistance and skew reduction, etc. Based on the four spinning method’s yarn count range , the paper predicted the market structure of spinning in the future.The future development of air-jet vortex spinning was also viewed in terms of production cost.

Key words: air-jet spinning; yarn; knitted fabrics; spinning methods
