A NEW WAY TO THE OBJECTIVE HAND EVALUATION

摘要

In present paper a new method named BM technique leading to the objective hand evaluation is presented. The method is based on the evaluation of 8 measurable properties using instruments occurring commonly in textile laboratories. The properties were selected from four basic groups of properties corresponding to the hand sensory centre. As prediction equation the ordinal logistic regression was applied. At first the total hand value (THV) of 90 men suits was evaluated subjectively using the panel of 40 respondents and median category M of eleven degree ordinal scale was calculated for each fabric. From 90 fabrics the set of 80 ones was applied for creation of the prediction formulae. The rest 10 fabrics served for verification of prediction ability. Prediction ability of BM techniques was compared with the same approach but on the properties obtained from KES system. Also 2 types of prediction equation derived on the basis of analysis from BM properties were compared. Results flowing from both sets of properties and 4 equations show the comparable results. The most of 10 fabrics was objectively classified to the category M±1 in comparison with subjective evaluation.%V příspěvku je představena nová metoda (BM technika) pro objektivní hodnocení omaku. Je použito 8 vlastností. Pro konstrukci predikční rovnice byla použita ordinální logistická regrese. Výsledné predikce byly porovnány s výsledky z obdobné predikční rovnice, kde však byly pro konstrukci použity vlastnosti ze systému KES. Výsledky ukazují na dobrou predikční schopnost navrženého modelu.
