This research carried out the comprehensive evaluation of double weft-knitted fabrics using the mathematical approach which is the product of the selected main mechanical characteristics and weighted factor vector(A). In this study, each mechanical characteristics which are resulted from the expecting 6 deformations of double knitted fabrics transformed into the meaningful value of hand scale by fuzzy transformation matrix(R). And another indispensible element is the weighted factor vector, which was deduced from a survey of panels of judges (N=30). The conclusions of this study give not only a similar tendency with KES-FB system, but also a reliable hand evaluation in industry, research and marketing.
