Aiming at the problems of poor objectivity,low efficiency and low accuracy in the identification methods of down feath-er species,an identification method used by near infrared spectroscopy was proposed in this study.The structural composition,chemical and optical properties of goose feather,goose plush,duck feather and duck plush were quantitative evaluated by the near infrared spectrum.Moreover,the feasibility of the method was confirmed by principal component analysis.The results indicated that the comprehensive recognition degree of transmission infrared spectrum is 50％～60％,and the comprehensive recognition degree of diffuse infrared spectrum is 70％～80％.The near infrared spectroscopy method can qualitatively identify the category of down feathers.This identification method is conducive to improve the product quality assurance of plush,safeguard the rights and interests of consumers,promote the standardized development of the market,and provide reference for practitioners and testing per-sonnel in related industries.
