In this study, a new measuring device has been developed to assess the formability of the curved surface of plane fabrics in relation to the pressure on fabrics. And then, the formability of five kinds of fabric was measured and assessed by this device.
An experiment has shown that creases were produced on fabrics at 0.094—0.134cm^-1in curvature, assuming that the maximum curvature of the curved surface on the human body is 0.2cm^-1. The value of the pressure applied on a fabric is 18-24g/cm², which was much lower than the 40g/cm²tolerable for the human body. A fabric should be finished to improve the formability without increasing the pressure on a fabric, provided that the pressure at which a crease is produced is a criterion of the formability of the curved surface.

This research aims to investigate the effect of physical properties of lining on wearing comfort. The survey on comfort sensations is carried out in summer and winter by wearer trial of skirts, linings of which are made of different types of fibre, and factors relating to wearing comfort are analyzed. Linings are conditioned under four cases corresponding to actual humidity and sweating conditions in summer and winter. Mechanical and surface properties and heat and water transport properties of lining are measured and these properties are related to comfort sensations. As a result, it is found that viscose and cuprammonium rayon are comfortable in summer by wearer trial. The cool/warm feeling is related to gmax and to heat loss, easiness of slip is related to friction coefficient, softness and tactile sensation are related to bending, shearing and compressional properties. It is shown that in summer viscose and cuprammonium rayon are cool and soft, and in winter silk is warm and clinging, and there is no difference among all materials except silk fabric.
