Embodiment 1
[0031] Step 1: Prepare transfer substrate
[0032] Using water as a solvent, stir the substrate at room temperature with an electric stirrer at a speed of 500 rpm for 3 hours to prepare a light yellow viscous transfer substrate with a viscosity of about 500 mPa·s. The substrate formula is: 0.5% guar gum, 0.5% tamarind, 1% water-soluble polyester hot melt adhesive, 0.5% sodium carbonate, 0.5% urea, 0.5% glycerin, and 0.5% dicyandiamide.
[0033] Step 2: Paper Coating
[0034] The substrate is evenly coated on the paper surface with a squeeze roll coater, and the coating thickness is 0.2 mm.
[0035] Step 3: Drying and calendering
[0036] Dry the paper in an oven at 40° C. for 30 minutes, take it out, and then calender it at room temperature with a pressure of 2 MPa to prepare dry heat transfer printing paper.
[0037] Ink-jet the above printing paper with reactive dye ink to prepare ink-jet dry heat transfer printing paper. Then heat and press the unpretreated dry silk fab...
Embodiment 2
[0039] Step 1: Prepare transfer substrate
[0040] Substrate formula: sodium carboxymethylcellulose 6%, water-soluble polyester hot melt adhesive 4%, sodium trichloroacetate 5%, urea 5%, glycerin 5%, dicyandiamide 4%.
[0041] Using water and ethanol as solvents, the above substrate was stirred at room temperature with an electric mixer at a speed of 800 rpm for 6 hours to produce a milky white viscous transfer substrate with a viscosity of about 5000 mPa·s.
[0042] Step 2: Paper Coating
[0043] Use a coating machine to evenly coat the substrate on the surface of the paper with a coating thickness of 1 mm.
[0044] Step 3: Drying and calendering
[0045] Dry the paper in an oven at 70° C. for 10 minutes, take it out, and then perform calendering at room temperature with a pressure of 0.1 MPa to prepare dry heat transfer printing paper.
[0046] Ink-jet the above printing paper with reactive dye ink to prepare ink-jet dry heat transfer printing paper. Then heat and press ...
Embodiment 3
[0048] Step 1: Prepare transfer substrate
[0049] Substrate formula: sodium alginate 3%, water-soluble polyamide hot melt adhesive 3%, sodium bicarbonate 1.5%, trisodium phosphate 1.5%, urea 4%, dicyandiamide 1%.
[0050] Using water and isopropanol as solvents, the above substrate was stirred with an electric stirrer at 600 rpm for 4 hours at room temperature to produce a light yellow viscous transfer substrate with a viscosity of about 3000 mPa·s.
[0051] Step 2: Paper Coating
[0052] The substrate is evenly coated on the paper surface with a squeeze roll coater, and the coating thickness is 0.5 mm.
[0053] Step 3: Drying and calendering
[0054] Dry the paper in an oven at 60° C. for 15 minutes, take it out, and then calender it at room temperature with a pressure of 0.5 MPa to prepare dry heat transfer printing paper.
[0055] Ink-jet the above printing paper with reactive dye ink to prepare ink-jet dry heat transfer printing paper. Then the dry modal / milk silk blend...
