In the coated fabrics, the textile component provides such the mechnical properties as tensile strength and elongation, and the resin component plays a roll for protection against the environment to which the fabric is subjected. The changes in the mechanical property of woven fabric caused by coating finish are discussed in this study. Plain weave fabrics are calendered and then coated with polyurethane or acrylic resin on one side of it. The tensile, shearing and bending properties of the fabrics are measured. Each property is compared with that of original fabric. The summary of results is shown as follows. (1) The anisotropy of tensile property in plain weave fabric is reduced significantly after coating with a thin layer of resin. (2) The coating finish increases remarkably shear and bending rigidities of the base fabric. (3) The changes in mechanical property of the base fabric, such as above mentioned, become small by fluoro resin pretreatment. (4) The effect of resin coating on the structural deformation of the base fabric takes place sensitively in an early stage of tensile process.
