Abstract

PURPOSE:To improve solidity by producing a diaphragm from a material prepared by inserting a thermoplastic film between 2 fibrous layers containing water, laminating these films and unifying these by heating and pressing. CONSTITUTION:A natural fiber layer 1 or a mixed fiber layer 1 composing of natural and synthetic fibers is stuck to both the front and back surfaces of a thermoplastic film 2 such as polyprophylene and polyethylene and these are unified under heating and pressing by using the thermal adhesion of the film 2.
