Clothing Pressure due to Stretch Fabrics (Part 1)

Effecting Factors on the Clothing Pressure

Abstract

Function and comfort in wearing the stretch fabric garments are governed by the clothing pressure. This report deals with the relations between the clothing pressure caused by the hoop tension of three different types of nylon-polyurethane stretch fabrics such as hard, medial and soft nature, and the stress-strain properties of the fabrics. The regions on which clothing pressure had been sited were medium of the upper arm and of the thigh. Subjects were 20 female students. Results were as follows :
1. There was a linear relationship between clothing pressure and tensile-elongation of each fabric (γ=0.970.91). The slopes of the regression equations, however, being different among them, increased with the tensile-tension of the fabrics and decreased with the radius of curvature of the bodies.
2. A regression equation Y=0.579X+2. 085 was obtained between the measured clothing pressure and the estimated value that was calculated from the stress-strain properties of the fabrics and the curvature of the bodies by an equation N=P/dγ g/cm².
