Description

Technical Field

[0001] The invention belongs to the technical field of polyester cloth, and in particular relates to a production method of digital transfer printing polyester cloth. Background Art

[0002] Digital waterless printing refers to the printing of various fiber fabrics, including various plant fibers and fabrics blended with chemical fibers, protein fibers and their blends. Since the advent of inkjet sublimation transfer paper, it has ushered in a new era of digital printing of polyester fiber fabrics due to its convenience and clean production. People naturally think of copying the process to other fiber fabrics such as cotton fibers, so various attempts have emerged, and innovators have come one after another, with a lot of exciting and sighing lessons. The American "Onestep Papers" company invented a cotton inkjet sublimation transfer paper, which is first coated with a layer of wax on the original paper surface, and then coated with a thin layer of sublimation dye receiving glue layer. When used, print the thermal transfer ink on the glue layer, and then attach the printed surface to the cloth surface for thermal sublimation transfer, so that the glue penetrates into the fabric, and it looks like a polyester cloth with thermal sublimation transfer. Because it is hot-tear by hot-melt wax, the cloth feels slippery like wax, but it is still as stiff as canvas. Those skilled in the art are in urgent need of developing a production method for digital transfer printing polyester cloth to meet existing usage requirements and market demand. Summary of the invention

[0003] The purpose of the present invention is to provide a production method of digital transfer printing polyester fabric to solve the above technical problems.

[0004] A method for producing a digital transfer printed polyester fabric comprises the following steps: (1) Preparation of polyester grey fabric: subjecting the polyester grey fabric to plasma treatment; (2) Drawing, coloring, and printing on water transfer paper, adjusting the humidity of the water transfer paper, and the water transfer paper; (3) Transferring: placing the polyester grey fabric and the water transfer paper on the machine, squeezing out the moisture between the polyester grey fabric and the water transfer paper, and pricking out the raised blisters with a needle. After air drying for 6 to 8 hours, place the paper in a 60 to 65°C oven and bake for 20 to 30 minutes. Then, spray 90 to 95°C hot water on the back of the transferred water transfer paper to dissolve it and tear off the base paper. Place the paper in a 140 to 150°C oven and bake for 10 to 20 minutes. (4) Varnishing: Dry the varnish on the surface of the transfer pattern.

[0005] Furthermore, the water transfer paper comprises base paper, water-soluble glue, and resin ink, and the thickness of the water transfer paper is 0.3-0.5 mm.

[0006] Furthermore, the polyester grey fabric has a unit area mass of 100-200 g / m 2 .

[0007] Furthermore, the varnish is polyurethane varnish, and the amount of varnish is 6-10 g / m 2 .

[0008] Furthermore, the plasma treatment power is 80-120 W, the pressure is 30-40 Pa, and the treatment time is 20-30 s.

[0009] Furthermore, the transfer temperature is 210-215° C., and the transfer time is 20-25 s.

[0010] The present invention has the following beneficial effects: The invention discloses a production method of digital transfer printing polyester cloth. The method comprises the following steps: under computer control, according to pattern design requirements, ink containing a colorant is sprayed on water transfer paper containing water-soluble glue by digital inkjet printing to form a required pattern, and then steps such as transfer, hot water dissolution, air drying, drying, and varnishing are adopted. The water transfer paper has a large code surface density, is not easy to produce wrinkles, and has high production efficiency. The base paper is torn off by hot water dissolution, and the operation is simple. During transfer, disperse dyes in resin ink are sublimated and transferred. Since the affinity between the dye and the polyester grey cloth is greater than the interaction force between the dye and the water-soluble glue, the dye is adsorbed and dyed on the polyester to complete printing. The varnish on the surface of the transfer pattern is dried, and the transfer pattern is wear-resistant and not easy to change color, so as to obtain the digital transfer printing polyester cloth.
