Research status and prospect for cotton fiber maturity measurements

Cotton fiber maturity is very important for cotton-textile in raising efficiency,assuring the quality of fiber and end products.It is the main indicator of grades assessment in national cotton standard.The principle of cotton fiber maturity measurements and the current research situation at home and abroad are introduced with their virtues and drawbacks.Through a comparative analysis of various measuring methods in terms of speed,efficiency and accuracy,this paper points out that the image processing method based on the longitudinal image of the fiber is an effective way for realizing fast,objective and accurate measurement of cotton fiber maturity.There are bright prospects for the automatic measurement system based on image analysis.But the problems such as sharp image acquisition and feature parameters procurement are needed to be solved.
