Basic mechanical properties and surface properties of sportswear fabrics are measured and those parameters are regressed with subjective values concerning extension recoverability and body motion restriction. Objective evaluation equations for items such as "Stretchy", "Recoverable", "Good handle", "Strong restriction", "Easy to move", are developed from the mechanical parameters.
　"Stretchy" sportswear fabrics are highly agreed with "Easy to move" fabrics, and are negatively coincident with "Strong restriction" fabrics in the point of correlation coefficients between subjective evaluation and the coefficients of those objective evaluation equations. These three items have high correlation with EMT-1 (maximum elongation in wale direction), and are determined mostly by the value. This result corresponds to the manner of subjective evaluation test, in which panels bend and stretch sportswear fabrics in wale directon with their elbows.
　"Recoverable" is decided mainly by maximum elongation in course direction.
