NON-DESRTRUCTIVE EVALUATION OF FUNCTIONAL FABRICS

摘要

The present invention provides a method for determining the functionality remaining in a functional fabric, the method comprising the steps of: providing a functional fabric having a known original functionality, a current wear, and a current unknown functionality, providing a light source, providing a detector, optically measuring the current wear using the light source and the detector, and evaluating the current unknown functionality using a correlation that expresses the current unknown functionality as a function of the current wear, optionally the detector further comprises a digital camera, and wherein the method further comprises the step of: obtaining an image of the functional fabric and quantifying the fractal dimension using a box-method fractal analysis on the image. The method may be applied the insecticide treated fabrics. The present invention further provides a method for determining the amount of functional compound remaining in a functional fabric, the method comprising the steps of: providing a functional fabric having a functional compound, a known original functional compound loading, a current wear, and a current unknown functional compound loading, providing a light source, providing a detector, optically measuring the current wear using the light source and the detector, and means for evaluating the current unknown functional compound loading using a correlation that expresses the current unknown functional compound loading as a function of the current wear-based damage.
