Abstract
The present invention provides a method for determining the functionality remaining in a functional fabric, the method comprising the steps of: providing a used 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 a magnified 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.
