The present invention provides a novel pretreating agent to improve the effect of ink-jet printing on polyester fabric and its application, and this invention belongs to the field of digital ink-jet printing. Stirring the dispersing agent, which includes many procedures of wetting agent and deionized water in a stirrer, adding nano-porous oxide dispersoid. Furthermore, keep stirring for 30 min and put the mixture in a sand mill to grinded for 2 h, then nano-porous oxide dispersoid is eventually got. The nano-porous oxide dispersoid work as pretreating agent, which used in the polyester fabric, is treated like pretreating agent during the padding process. By applying this technique into double-sided permeation ink-jet printing and direct-injection ink-jet printing, its pattern's definition, color depth and color saturation could be remarkable enhanced. This method has many advantages such as the craft is easy to handle as well as the operation is simplified, it is also suitable for batch production of the polyester fabric.
A polyester fabric pretreating agent, comprising 10-50 wt % nano-porous oxide dispersoid, 1-4 wt % antistatic agent, 1-5 wt % thickening agent, 1-5 wt % wetting agent, and water;
