ということも少なくなった。Furthermore, the paper-like material thus obtained is
It is made from silk, which is highly hygroscopic, lightweight, tough, and flexible, and the short silk fibers are welded to low-melting synthetic fibers, making it superior to conventional paper made from wood. It has high water resistance, mechanical strength, dimensional stability, etc., and the fibers do not shift during printing, and even when it gets wet, the strength and dimensional stability do not decrease like conventional paper. There is no more blurring of written letters, etc.
