In the sale of clothing using electronic commerce, it is difficult to convey the fabric hand information of clothing to consumers. In this report, we investigated how the fabric hand of clothes is expressed in actual e-commerce. In addition, a student awareness survey revealed what kind of information consumers are looking for when purchasing clothes through e-commerce. As a result, the fabric hand was expressed mainly on the “product image” and “product description” on the EC site. In some cases, the fabric hand was expressed by about 3 levels of indicators, but no objective indicators were found. Consumers were looking for more information about the fabric hand in e-commerce. More detailed information was sought on the “thickness” and “transparency”, “drape” and “Hari” of the fabric. From the above, the challenge in e-commerce is to express the fabric hand using objective indicators of the physical properties of the fabric so that it can be easily communicated to consumers.

In this study, a polyurethane (PU) resin is synthesized using a new type of polycarbonate diol (PCD) that contains isosorbide (ISB），which is a plant-derived raw material. The synthesized PU resin is applied to the skin layer of synthetic leather. The characteristics of the synthesized PU resin are investigated. The glass transition temperature (Tg) of the synthesized PU resin is 78°C, which is extremely high. In addition, when the synthesized PU resin is mixed with conventional PU resin, wrinkles can be formed on the surface of the synthetic leather according to the required usage ratio. Although it affects the surface texture of the synthetic leather, the flexing endurance test performed at -10°C shows a practically usable region.
