Problems solved by technology

The shortcomings of this technology using thermal transfer inkjet printing are: the cost of transfer paper is relatively high, and the process flow is relatively long. In addition to the printer, drying equipment and pressing machines are also required, which require more equipment and occupy an area. Larger, high cost of printing process, waste transfer paper will pollute the environment

Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. Sublimation ink direct printing process of the present invention comprises the following steps:

[0014] 1. Apply slurry on the polyester fiber cloth to prevent the sublimation ink from penetrating when it is printed on the surface of the polyester fiber cloth. Use an electric padding car, such as the PB-1 electric uniform padding car of Taiwan Rapid Company. The line speed of the process position is greater than 0 to 18 meters per minute, and the excess rate is 70%, and the excess rate=the weight of the slurry on the cloth / the weight of the cloth itself, and it is dried at no more than 100 ° C according to the prior art.

[0015] The slurry is composed of the following mass ratios: 1-2% water-soluble high molecular polymer, 0.5-1% waterproofing agent, 0.5-1% anti-swimming agent, 0.5% anti-reducing agent, 0.1-1% preservative, The rest is water....

Abstract

The invention discloses a thermal sublimation ink as well as a direct printing technology and equipment. The invention aims to solve the technical problem that the printing cost of polyester fiber cloth is lowered. The thermal sublimation ink comprises the following components in percentage by weight: 20-35% of dispersed dye, 5-10% of dispersing agent, 15-25% of organic solvent, 0.4-1.5% of surfactant, 0.1% of preservative and 40-59.5% of deionized water. The printing technology disclosed by the invention comprises the following steps: coating slurry on the polyester fiber cloth; and printing the thermal sublimation ink on the polyester fiber cloth by a printing machine. The equipment disclosed by the invention is characterized in that a printing system is composed of a printing head and an ink supply system connected to the printing head. Compared with the prior art, the thermal sublimation ink is characterized in that the thermal sublimation ink is directly printed on the sized polyester fiber cloth, the ink develops color on the cloth to form an image. The technical process is short, thus the production efficiency is greatly improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to a synthetic fiber printing ink, printing process and equipment, in particular to an ink for direct printing on polyester fiber cloth by using a printer, as well as the printing process and equipment. Background technique [0002] In the prior art sublimation inkjet printing process on polyester fiber cloth, the printing pattern is first printed on transfer paper, and the transfer paper and polyester fiber cloth are hot-pressed or hot-rolled at 210°C for about 3 minutes. The disperse dye is sublimated and transferred from the paper to the polyester fabric to complete the printing process. The shortcomings of this technology using thermal transfer inkjet printing are: the cost of transfer paper is relatively high, and the process flow is relatively long. In addition to the printer, drying equipment and pressing machines are also required, which require more equipment and occupy an area. Larger, high cost of printing process, and...
