Abstract

An ink tube (10) for an ink jet printer is formed by using a thermoplastic elastomer composition, having a Shore-A-hardness of not more than 70, which comprises an olefin thermoplastic resin and a rubber component, containing not less than 30 wt % of butyl rubber, which is dispersed finely by dynamic vulcanization the rubber component in the olefin thermoplastic resin. It is preferable to extrude the thermoplastic elastomer composition tubularly by a resin extrusion method.

Description

technical field [0001] The present invention relates to ink tubes for inkjet printers; in particular, the present invention relates to use in cleaning inkjet printer inkjet heads for removing waste ink from inkjet heads, or for removing ink from inkjet heads. The gutters are supplied to the ink tubes of the inkjet head. Background technique [0002] In an inkjet printer, ink tubes necessary for delivering ink are connected to an inkjet head. Such ink tubes are used to remove waste ink from the inkjet head when cleaning the inkjet head of the inkjet printer, or to supply ink from the ink tank to the inkjet head. [0003] The liquid ink printer using ink tubes proposed in JP-A-10-29317 is a liquid ink printer equipped with a liquid ink printing head and an ink circulation device. [0004] Since the ink must be sucked out while squeezing the hose when the ink is discharged, it is required that the hose must have good recovery performance after being deformed by extrusion, etc...
