PRODUCTION METHOD FOR FIBROUS LAYERED PRODUCT, FIBROUS LAYERED PRODUCT PRODUCED THEREBY, LIQUID-STORING CONTAINER HOUSING FIBROUS LAYERED PRODUCT AND LIQUID DISCHARGE HEAD CARTRIDGE HAVING THE CONTAINER

摘要

PROBLEM TO BE SOLVED: To obtain a fibrous layered product not having the needless compressive set in a downward direction along the gravitational direction, having a uniform density, excellent in wettability to ink and useful e.g. for a liquid-holding container by controlling the influence of gravitation acting on a layered product made up from a fibrous material in a thermal process. SOLUTION: This fibrous layered product is obtained by controlling in a thermal process the influence of gravitation acting on a layered product made up from a fibrous material such as fibers made of a thermoplastic olefin-based resin and mutually put side by side in nearly the same direction. The process for controlling the influence of gravitation is performed through operation rotating the layered product made up from a fibrous material in which the central axis of the rotational operation intersects the direction of the fiber and also falls at right angles with the gravitational direction. A liquid-holding container preferably is constituted in such a way as to hold the fibrous layered product and to store a liquid used for recording, and a liquid jetting head cartridge equipped with both the above container and a liquid jetting head capable of jetting the liquid stored in the container preferably is manufactured.
