The stiffness of fabrics was evaluated by means of heartloop method employing the draping quality as its measure. The change in the stiffness caused by laminating non-woven interlining was investigated. Six kinds of wool and cotton materials were used as the sample fabrics.
Effects of several factors such as the kind of texture, thickness and weight of fabrics on the stiffness and the feel of the material were also examined. The stiffness of the laminated fabric was found to be proportional to that of the outer fabric irrespective of the interlining. The increase in the stiffness caused by lamination varied with the angle between the directions of texture and of measurement. The stiffness showed its maximum in the direction of 30° for all materials studied, while values of stiffness larger than those expected from Peirce's equation were obtained in the 60° direction for all fabrics except plain-woven materials.
The possibility of presuming the stiffness of laminated fabrics was pointed out on the basis of the present results.
