Attempts have been done to make clear the physical frictional meaning of smooth slicky feeling so called "Numeri" between wool fabrics and to evaluate the "Numeri" feeling of knitted fabri cs as mechanical characteristics, which had been judged with a sensory panel test by human hand.<BR>Analizing the fingers' action of handling at "Numeri" sensory test, it is realized that "Numeri" of knitted fabrics depends on the dynamic frictional behavior between fabrics under finger pressure of 300 up to 1300 g.<BR>This frictional "Numeri" characteristics can be duplicated in figure by means of enlarged measurement of stic-slip friction-slip distances curve by a specially designed heavy loading frictional tester between knitted fabrics. Moreover, the rate of frictional depression at slipping (NI) of an enlarged curve shows good agreement with "Numeri" marks of sensory test.<BR>The heavier the loading, the more distinguishable th difference of this frictional character among test samples as same as high fingers' pressure is found to judge the slight difference of "Numeri" by hand.
