Cashmere plays an important role in luxury factory due to its characteristic. In frame of "green economy", many companies start to produce and market recycled cashmere textiles [1]. In order to have a correct identifiation of fiers, NIR spectroscopy can be applied to analyze and distinguish virgin and recycled cashmere fiers. Since no signifiant diffrences can be seen in the recorded spectra, the PCA analysis combined with the SIMCA method allows the classifiation of the fiers in two distinct classes. Quantitative analysis was carried out using samples obtained by carefully mixing known amounts of recycled and virgin cashmere fiers.

Abstract
Cashmere plays an important role in luxury factory due to its characteristic. In frame of "green economy", many companies start to produce and market recycled cashmere textiles [1]. In order to have a correct identifiation of fiers, NIR spectroscopy can be applied to analyze and distinguish virgin and recycled cashmere fiers. Since no signifiant diffrences can be seen in the recorded spectra, the PCA analysis combined with the SIMCA method allows the classifiation of the fiers in two distinct classes. Quantitative analysis was carried out using samples obtained by carefully mixing known amounts of recycled and virgin cashmere fiers. These preliminary results confimed that the NIR coupled with chemometric methods might be a useful tool for a rapid screening of cashmere fiers quality.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
