The invention sets forth a method for determining the hand quality of a fabric or other material. The invention establishes a new constant value to be applied to this determination. The constant value is referred to as the Quality Energy Value (hereinafter the "QE value") of a material. The QE value takes into account the reciprocatory motion actually used when rubbing a piece of cloth with a finger to subjectively determine the hand quality of a fabric. The invention utilizes a testing apparatus which simulates this sliding motion of finger on fabric. The QE value also advantageously takes into account the velocity at which the frictional properties of the fabric are measured. It has been found that the lower the QE value, the better the quality of the fabrics. Accordingly, using the method of the invention, a range of QE values may be established for a variety of fabrics, and, thereby, the relative hand qualities of the fabrics may be compared.
