Abstract
The invention relates to a method for rapid discrimination of polyvinyl chloride fibers in a garment fabric. The method comprises the following steps: scissoring and splitting the garment fabric into pieces so as to obtain composite fibers; preparing a sample from the composite fibers and testing the sample on an X-ray fluorescence spectrometer so as to obtain testing results; and observing whether elemental chlorine is included in the experimental results, and determining that the garment fabric contains the polyvinyl chloride fibers if elemental chlorine is included. The method employs the X-ray fluorescence spectrometer to test elements in the garment fabric; although the X-ray fluorescence spectrometer cannot determine elements like C, N and H in fibers like acrylic fibers, polyvinyl, terylene and chinlon, the X-ray fluorescence spectrometer can determine the characteristics of elemental Cl; so the method realizes high-precision high-efficiency discrimination of the polyvinyl chloride fibers in the garment fabric and can be extensively applied to detection of garment fabrics.
