The mechanical actions involved in recycling cashmere fibers, notably from woven fabrics, cause fiber damage. There are three distinct forms of damage: partial cleavages, axial fractures, and short fibers. Fisher's discriminant analysis techniques are applied to two groups of cashmere fibers, new and recycled. The discriminant function is tested on additional samples from the two groups, all of which are correctly allocated. Thus, the model is apparently capable of distinguishing between new and recycled cashmere fibers.
