Abstract

The invention relates to the technical field of textile dyeing and finishing, and discloses a digital transfer printing method using plant dye ink. The method comprises the following steps: (1) coating the surface of blank paper with a paste material, drying and calendering to obtain transfer paper; (2) mixing a humectant with a part of ultrapure water to obtain a humectant solution, mixing a plant dye with a part of ultrapure water to obtain a plant dye color paste, adding the plant dye color paste, a surface tension regulator, a viscosity regulator, a pH buffer agent, an antiseptic bactericide and the rest ultrapure water into the humectant solution, stirring, and carrying out ultrasonic treatment, and carrying out filtering through a water-based filter membrane to obtain plant dye ink; (3) spraying and printing the plant dye ink onto transfer paper, forming a printing pattern on the transfer paper, attaching the dry fabric to the printing surface of the transfer paper, then ageing, and stripping the fabric from the transfer paper to obtain a transfer printing fabric; and (4) washing the transfer printing fabric, and carrying out color fixation treatment. The method has the advantages of simple process, high controllability and the like.

Description

technical field [0001] The invention relates to the technical field of textile dyeing and finishing, in particular to a digital transfer printing method using vegetable dye ink. Background technique [0002] Digital transfer printing has the characteristics of high printing precision and strong three-dimensional pattern, and is suitable for small batch, multi-variety, and quick-response production methods. The earliest digital transfer printing invented is sublimation transfer printing, which uses sublimation disperse dye ink to print thermoplastic fabrics such as polyester, and is good at printing moiré and gradient patterns. But this method is not suitable for natural fiber fabrics such as cotton, linen, silk. [0003] Wet transfer printing is suitable for natural fiber fabrics. Before printing, the fabric should be pre-wetted. The dye on the carrier is dissolved by the water on the fabric surface and migrates to the fabric under the capillary effect. Therefore, wet tran...
