    Abstract  Various detection technologies for plastic film foreign fibers in raw cotton were discussed.Physical properties of plastic film were introduced.Advantages and disadvantages of four existing plastic film foreign fiber detection technologies were analyzed,such as infrared detection,ultrasonic detection,transmission polarization detection and reflected polarization detection.In combination with domestic optical device processing level and cost control considerations,according to plastic film removal efficiency of various foreign fiber machines in actual use,it is considered that reflected polarization detection plastic film technology is the best solution for domestically produced foreign fiber machines.
