Summary: | To provide an aqueous cleaning liquid which can prevent reduction in the discharge performance of ink even when resumption of discharge of ink is tried, or the operation temperature of an ink jet recording device changes within the temperature range between 10°C and 40°C.SOLUTION: An aqueous cleaning liquid cleans a surface to which aqueous ink is discharged in an ink jet recording device. Specifically, the aqueous cleaning liquid includes nonionic surfactant, glycols and glycol ether. The nonionic surfactant includes amine type surfactant. The viscosity (25°C) of the aqueous cleaning liquid at drying is equal to or greater than 9 mPa s and equal to or less than 13 mPa s. The E/R value in Andrade's equation is equal to or greater than 3.15×10mPa s×K and equal to or less than 3.45×10mPa s×K.SELECTED DRAWING: Figure 4
【課題】インクの吐出の再開を試みた場合であっても、また、インクジェット記録装置の動作温度が10℃以上40℃以下の温度範囲で変化した場合であっても、インクの吐出性能の低下を防止可能な水性洗浄液を提供する。【解決手段】水性洗浄液は、インクジェット記録装置において水性インクが吐出される面を洗浄する。詳しくは、水性洗浄液は、非イオン性界面活性剤と、グリコール類と、グリコールエーテル類とを含有する。非イオン性界面活性剤は、アミン型界面活性剤を含む。乾燥時の水性洗浄液の粘度(25℃)が、9mPa・s以上13mPa・s以下である。アンドレード式におけるE/R値が、3.15×103mPa・s×K以上3.45×103mPa・s×K以下である。【選択図】図4 |
