In the previous report the authors studied the anisotropic tensile and bending properties of the outer material and interlining of lapel. In the present paper the authors have studied the effect of padding stitches on the constancy of the dimension of the lapel and found the increase of the thickness, the contraction of the width, the elongation of the length, and the change in the bending modulus, of the combined material sewed by padding stitches. The padding stitches were sewed by hand and by machine. The machine-made stitches were blind stitches and zigzag sewing. The results obtained are as follows : 1. The combined material is lengthened or contracted by the padding stitches. Therefore the seam allowance at the lapel line should be appropriately adjusted according to the different kinds of interlining. 2. The bending modulus of the combined material depends on the padding stitch method. 3. The significant effect of the padding stitches on the bending modulus of the materials is observed in the case of the machine-sewed padding stitches.
