Abstract
It is necessary for a clothing design to predict and control the compound bending rigidity of the reinforced composite. The compound bending rigidity relates to the formability and form retention of the reinforced fabrics on a curved surface of garments. This paper aims to predict the compound bending rigidity of reinforced fabrics from those of each constitutional component. The results are summarized as follows :
(1) On the assumption that a face fabric, fusible interlinings and their composite fabrics are elastic, the compound bending rigigity can be predicted by applying the bending equation of combined beams. Correcting coefficients have been given for each construction of base fabrics of interlinings to predict the compound bending rigidity.
(2) The compound ratio of the bending rigidity is varied from 2.0 to 9.7 depending on the structure of base cloth of interlinings. These values are found to be closely related to the tensile properties of face fabrics and interlinings. An equation has been derived to represent the compound ratio by tensile strain at 100 gf/cm. The compound ratio tends to be lower as the tensile strain ε1 of interlinings is greater and the ratio εf2/εf1 of weft to warp tensile strains of face fabric is larger.
