Surface treated fiber body, liquid container using fiber absorber and method for producing fiber absorber for use in liquid ejection

摘要

A fiber body which exhibits sufficient ink supplying characteristics for keeping up with the trend toward diversification of ink and high printing speed while ensuring an easy and simple ink injection operation and a liquid container having the same. The ink tank 1 has a PP fiber body (crosshatched area of the figures) 2, as a negative pressure generating member for an ink jet head which ejects liquid to perform recording, arranged almost all over the interior thereof, so as to allow the fiber body to hold a liquid to be supplied to an ink jet head. On the top of the tank casing, provided is an atmosphere communication port 3. And as a PP fiber body 2, used is an assembly of intertwined PP fibers of which surface has been subjected to surface treatment of giving hydrophilic nature thereto. <IMAGE>
