Abstract
An elastically stretchable composite sheet that includes an elastic layer and an inelastic layer formed with stretchable fibers having a relatively small diameter and bonded to at least one surface of the elastic layer. In the inelastic layer bonded to the elastic layer is formed with thermoplastic synthetic fiber, at least 80% by weight of stretchable fibers includes thermoplastic synthetic fiber containing lubricant of 0.1˜5.0% by weight.
Claims4
An elastically stretchable composite sheet comprising:
- an elastic layer that is elastically stretchable in at least one direction;
- and
- an inelastic layer that is inelastically stretchable in said one direction and bonded to least one surface of said elastic layer, said inelastic layer comprising at least 80% by weight of thermoplastic synthetic fibers which contain about 0.1 to 5.0% by weight of a lubricant.
