Non-destructive Identification and Mixture Ratio Analysis of Cotton-Polyester Blended Textile Products by IR Spectroscopy

Modern textiles often contain cotton-polyester products which must undergo quality assurance processes. The ability to identify the mixture ratio analysis of these products for the manufacturer is a great advantage. Preferably these methods should be non-destructive and calculated quickly. Infrared spectroscopy was used to identify textile products by absorption and soft independent modeling of class analogy. Mixture ratio analysis was conducted by analysis of the absorption spectrum and partial least squares regression. The accuracy of mixture ratio analysis has reached 2.4 %.
