Abstract

The present invention provides a method of measuring stain removal of multiple stains from stained fabric (1), wherein the stained fabric (1) comprises one or more different types of stains, wherein the stained fabric (1) is placed in an apparatus (2), wherein the apparatus (2) comprises: a wash bath (3); rotating drum (4); compressive roller (5); means of applying tension to the stained fabric (6); unstained static fabric (7); means of applying tension to the static fabric (8), which converts into abrasion force between stained fabric and static fabric; image capture means (9); and image analysis means (10), wherein the stained fabric (1) is secured under tension on the rotating drum (4), wherein during each rotation, each type of stain on the stained fabric (1) is repeatedly contacted to the wash bath (3) at least once per rotation, wherein during each rotation, each type of stain on the stained fabric (1) is contacted to the compressive roller (5) which applies a compressive force to the stain, characterized in that the image capture means (9) is positioned such that the image capture means (9) measures in real time the light absorbance of each type of stain on the stained fabric (1) at least once during each rotation, wherein the stained fabric (1) comprises a visual cue (11), wherein the image capture means (9) can identify the visual cue (11), and the image analysis means (10) can associate the measurement reading for a type of stain with the visual cue for that type of stain , and distinguish between different types of stain on the stained fabric and in this manner read multiple different types of stains or sets on the same stained fabric.
