Method for manufacturing an absorbent fibre layered product
Abstract
(57) A summary and the purpose Offer the method of manufacturing simply the fiber layer equipped with large absorption capacity, and the absorbency fiber layer by it. Composition In the method of manufacturing an absorbency fiber layer (15), at least one material layer (16) which consists of mixtures of a natural fiber like a wood fiber and a plastic fiber is fabricated by dry pressing process technology, The mixture of a natural fiber or a natural fiber, and a plastic fiber and other material layers (17) which consist of super-absorbency material (18) are formed on the above-mentioned layer, and a fiber layer (15) is pasted up with heat. Super-absorbency material (18) is added by the 2nd material layer (17) formed in the dry pressing process process, 押 pressure of the upper surface of a fiber layer is carried out after that, and in order that the undersurface may compress the material layer (16) which is humidified and does not include super-absorbency material and may make it a liquid distribution layer, it is compressed by the high temperature calendering.
