Abstract:Clothing pressures were measured in relation to the covered area at the waist for waistnipper and waistband at a reduction rate of 2.5%. A sensory test was carried out on subjects in relation to the clothing pressure. Clothing pressures at the waist line (W.L) for the waistband, for which the area covered at the waist was narrower than that for the waistnipper, were higher than those for the waistnipper in standing position at rest. For rightward bending movement, on the other hand, the pressure at the middle axillary line for the waistnipper was higher than that for the waistband. However, at other regions and for other movements, the pressure for the former was lower than that for the latter. Clothing pressure for waistband at the scapular line and at 3cm outside the posterior median line changed remarkably by respiration as compared to those at other regions. These changes were larger than those for the waistnipper.These results indicated that the pressures at the same reduction rate at the waist changed due to the difference in area covered at the waist, and that respiration and the ability of samples to follow bodily movement affected the clothing pressure. Subjects' evaluations of clothing pressure at W. L during sensory test were as follows: (1) No sense or no discomfort when pressure was 0-15 gf/em'; (2) negligible or only slight discomfort when pressure was 15-25 gf/cm2; (3) extreme discomfort when pressure exceeded 25 gf/cm2.

Waistband pressures were measured by a hydrostatic pressure-balanced method to deter. mine the feeling of wear comfort quantitatively. The pressure developed under the standing erect and natu ral respiration conditions and wearing a waistband with a reduction rate of 5.0% was only 17.5 •} 2.1 mmHg on the average. Under various body conditions (position, movement and respiration), the waistband
