が、逆に不離布の強度がラミネート層の強度に依存する
ために引裂強度が低下するという問題がある。For this purpose, for example, some methods have been devised, such as dispersing a thermal adhesive binder in a non-woven fabric and heat-treating it to soften the fibers and threads, or laminating plastic on the surface of the non-woven fabric. Since the bonding between the fibers and yarns is only partial on a microscopic level, it is not possible to improve the 1!1 strength as much as desired, and the 711 strength of laminated products is not as good as the above to some extent. However, since the strength of the non-release fabric depends on the strength of the laminate layer, there is a problem in that the tear strength decreases.
