が多い。Conventionally, artificial leather has been produced by laminating a synthetic resin such as polyurethane on one side of a base fabric such as knitted fabric, woven fabric, or non-woven fabric, and artificial leather in which a synthetic resin layer is laminated on one side after the entire base fabric is impregnated with a synthetic resin solution. is known, but in the former, the back side is just a knitted fabric or non-woven fabric! It is exposed and can be distinguished from natural leather by looking at it, as well as impregnated cloth. 2 was also clearly distinguishable from natural leather in terms of appearance. Furthermore, these artificial leathers lack drapability in terms of texture, and especially those made from knitted fabrics are difficult to cut (cutting diagonally to the surface) when making T-shirts such as bags. Threads often come out due to skidding and spoil the appearance.

It is coated on release paper and reacted with the above to form a microporous urethane foam layer. Then, while it is still sticky, it is attached to the base fabric, heated and reacted, and then released with release paper. By peeling it off, or by directly applying the polyurethane-containing composition mixed with air in advance to the base fabric and heating and drying it.Furthermore, instead of applying the polyurethane-containing composition directly to the base fabric, first apply it on a release paper and heat it. A polyurethane layer is provided by drying and adhering to a backing fabric and completely peeling off the release paper.
