The invention discloses efficient preparation technology of a resin interlining material. The preparation technology comprises the following steps: A, adding hydroxy propyl methylcellulose, polyvinyl alcohol, and fumed silica into a compounding tank, performing mixing, adding 1/2 purified water, and performing full stirring to obtain a mixture A; B, adding an aldehyde trapping agent, palmitic acid and citric acid in sequence to the mixture A, performing mixing, adding 1/4 purified water, and performing full stirring to obtain a mixture B; C, dissolving a blue and violet liquid with a small amount of warm water, and performing filtration; and D, adding the filtered blue and violet liquid to the mixture B, adding 1/4 purified water after mixing, performing heating at a low temperature of 50 DEG C in a water bath after mixing, performing slow cooling till the obtained product reaches the room temperature, and performing standing for 2 h to obtain the resin interlining material. The preparation technology is simple and is easy to achieve. The preparation technology allows the tear resistance of an interlining of a shirt to be improved, the washing shrinkage to be reduced, and the quality of the shirt to be improved.
