Predictability between Sensory Factors and Physical Properties of Clothing during Exercise in a Cold Environment

Subjective responses on 19 sensory descriptors were ob-tained by exposing subjects in a cold environment of 14℃and 32％ RH,wearing T-sbirts made from eight fab-rics.Three factors were extracted from the sensory re-sponses using factor analysis.On the other hand,an ex-tensive range of fabric physical properties was tested onthe same eight types of fabric,including six types ofmeasurements on fabric transport properties and seventypes of measurements on fabric mechanical behavior.By principal component analysis,ten independent factorswere extracted from the objectively measured physical properties. Canonical correlation analysis is applied to the sen-sory factors and the physical factors to study relation-ships between objective measurements of the physicalproperties of fabrics and subjective sensory responses.Two canonical correlation coefficients were found to be highly significant(P 0.97). Canonical redundancy analysis showed that canoni-cal variables of the objective physical factors o
