せている。BACKGROUND OF THE INVENTION Conventionally, nonwoven fabrics have generally been made by bonding natural or synthetic fiber webs with synthetic rubber or synthetic resin. In recent years, non-woven fabrics have become lightweight and inexpensive, so they can be used as disposable clothing, such as dresses and leisure shirts, by folding them into small, portable cans that can be easily carried.Their elasticity recovers the moment they are taken out. The shape has been restored to a functional state.

indicates the state returned to before deformation by heating. (1) A nonwoven fabric sheet is formed by joining a web of resin fibers having shape memory properties such as polynorbornene, random, cross, or parallel with a resin binder.

特性を多様化させることができる。Incidentally, the tree W having the above-mentioned shape memory property! In addition to fibers, ordinary natural or synthetic fibers can be mixed and used to impart directionality to the fibers, and by varying the thickness and amount, the shape memory properties can be diversified.

数秒の内に元の形状に戻すことができる。In addition, polynorbornene resin has low hardness and can be freely deformed at room temperature, but its glass transition point is around 85°C, which is considerably higher than that of general rubber, and its molecular weight is nearly 10 times, so it takes a long time to restore its shape. However, by adding external energy (for example, immersion in boiling water), the relaxation time can be drastically shortened.
It can be returned to its original shape within seconds.
