Document Type and Number:
Japanese Patent JP3782772
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a sheet which can fully demonstrate the capability of charcoal and to provide a manufacturing method for such a sheet.
SOLUTION: A blend material of charcoal granules and thermoplastic resin granules is laid on the surface of a first nonwoven fabric layer G1, the laid blend material is covered with a second nonwoven fabric layer G2 to construct a three-layer structure S, and, after the three-layer structure S is heated to a temperature of such an extent wherein the shape of the thermoplastic resin granules remains, the pressurization processing and cooling processing are provided for the three-layer structure S. By this, the charcoal granules will not be covered by the resin and be made possible to demonstrate fully its adsorbent ability on harmful substances, and moreover there is no coming-off of the charcoal granules.
