Abstract: Scale pattern of cashmere are studied under light microscope. Scale pattern gene codes are used to describe the scale shape of fiber. The framework and classification of scale pattern gene code is studied. The correlation of scale pattern gene code is also studied. The results show that at the 0.05 level, the correlation between most scale pattern gene codes is significant. Only several correlations are not significant at the 0.05 level. These results imply that the overlaps exist in the recognition mechanism for different scale pattern gene code, which provide a direction in finding optimal gene group for the identification of cashmere.

Key words: cashmere, wool type fiber, scale, pattern gene code, identification
