Ink absorbing body, ink tank, ink-jet cartridge and ink-jet printing apparatus
First Claim
1. An ink absorbing body in an ink tank for use in an ink let printing apparatus, said ink absorbing body comprising fibers with capillary force between said fibers for storing ink,wherein said fibers exhibit a hydrophobic characteristic relative to the ink, and wherein on a surface of said fibers, before filling the ink into the ink tank, a nonionic surfactant is deposited within a range of 0.002 to 0.2 wt % relative to a weight of the ink, wherein the surfactant reduces influences of the ink absorbing body on characteristics of the ink retained by the ink absorbing body.

Abstract
An ink absorbing body stores an ink injected into an ink tank for an ink-jet with capillary force between fiber. On a surface of said fiber before filling the ink, a surfactant is deposited within a range of 0.002 to 0.2 wt % relative to a weight of the ink or in a range of 0.01 to 0.5 wt % relative to a weight of the fiber.

20. A production process of an ink tank for use in an ink let printing apparatus which includes an ink absorbing body comprised of fibers with capillary force between said fibers and a casing to house said ink absorbing body and having an atmosphere communicating portion, said fibers exhibiting a hydrophobic characteristic relative to the ink, comprising the steps of:
-
depositing a nonionic surfactant on a surface of said fibers before filling the ink tank with ink, the nonionic surfactant being deposited within a range of 0.01 to 0.5 wt % relative to a weight of the fiber, wherein the surfactant reduces influences of the ink absorbing body on characteristics of the ink retained by the ink absorbing body;
inserting said ink absorbing body into said casing; and
injecting ink into said ink absorbing body. - View Dependent Claims (21, 22)
