Embodiment 1
[0025] Embodiment 1 is a towel temperature-sensitive printing process disclosed by the present invention, and the specific steps of the printing process are as follows:
[0026] Step 1 is to prepare printing paint: 65 parts of modified silicone resin emulsion, octanol with a mass ratio of 0.2:0.4:0.4, 2 parts of a mixture of bisphenol A and pararosaniline hydrochloride, 0.7 parts of polyacrylate, trimerized Mix 0.7 parts of sodium phosphate, 18 parts of ethanol-water mixture, and 2 parts of carbonic acid solution with a concentration of 0.03mol / L, mix and stir, and heat for 3 hours, and the heating temperature is 60°C. Repeatedly add ethanol-water during the heating and stirring process The mixed solution is used to adjust the viscosity of the printing paint, and then the material is discharged after cooling down to below 35°C;
[0027] Step 2 is printing paint coating: apply the uniformly mixed printing paint on the surface of the towel gray cloth, and the number of coating l...
Embodiment 2
[0029] Example 2, the difference from Example 1 is that 2 parts of carbonic acid solution with a concentration of 0.03mol / L are deleted in step 1.
Embodiment 3
[0030] Example 3, the difference from Example 1 is that in step 1, 1 part of carbonic acid solution with a concentration of 0.03 mol / L is added.
