A liquid container includes a negative pressure generating member containing chamber which contains therein a negative pressure generating member formed of a fiber material and provided with a liquid supplying portion and an atmosphere communication portion. A liquid containing chamber, provided with a communicating portion communicating with the negative pressure generating member containing chamber, forms a substantially hermetically sealed space and stores therein liquid to be supplied to the negative pressure generating member. A partition wall for partitioning the negative pressure generating member containing chamber and the liquid containing chamber and forming the communicating portion, is provided with a gas introduction blocking unit which cooperates with the partition wall and the liquid contained in the negative pressure generating member containing chamber to block the introduction of gas from the communicating portion into the liquid containing chamber, except during the supply of the liquid from the liquid supplying portion to the outside.

A forming method for a fiber aggregate in which fibers are heated to be welded with each other includes a heating step of applying upward heated air to a bottom of a block of the fibers to pass the heated air therethrough and to cause the block of fibers to float, wherein at least parts of fibers are melted while the block of fibers float, and a compression step of compressing substantially in a vertical direction the heated block of fibers into a desired height. The compressed block of fibers is cooled to solidify melted portions of the fibers at portions where the fibers intersect with each other.

摘要:
A method for manufacturing a fiber aggregate formed by fiber having reforming surface comprises the steps of providing a fiber surface having thermoplastic resin at least on the surface layer thereof with a hydrophilic processing liquid containing polymer having a first portion with more hydrophilic group than the surface, and a second portion having interfacial energy different from that of the hydrophilic group, and interfacial energy substantially equal to the surface energy of the fiber; orientating the second portion toward the fiber surface, while orientating polymer to the side different from the surface of the first group; and forming a fiber absorber by heating the fiber having the reformed surface in the step of orientating polymer to thermally bond the contact points of fibers themselves. With this method of manufacture, it becomes possible to enhance the uniform property of the fiber aggregate still more, which is formed subsequent to making the property of such fiber aggregate uniform per unit of single fiber or small aggregate existing in any one of stages before the formation thereof.
摘要:
There is disclosed a liquid supply method in which a bubble is prevented from being retained or accumulated in a communication part. An upper wall surface of a joint pipe for connecting a negative pressure control chamber container to an ink container is inclined upward to the ink container from the negative pressure control chamber container. Since the upper wall surface of the joint pipe is inclined, the bubble flows into the ink container without being retained or accumulated on the upper wall surface of the joint pipe during gas-liquid exchange.
